Abstract
According to the Centers for Disease Control and Prevention (2012) African Americans
[AA] (444) have the highest prevalence of hypertension (HTN) when compared to Whites
(326) and Mexican Americans (283) The research team proposed a culturally-sensitive
educational intervention via tele-monitoring delivered by Advance Practice Nurses (APNs) in a
private family practice setting The goal is to reduce blood pressure (BP) readings in AA males
aged gt 40 years to within normal range of lt 12080 mmHg over a six-month period Stakeholders
include patients family members physician APNs and private practice staff Resistance may
come from staff and APNs because of additional work responsibilities in managing patients
Strengths of change include decreasing BP and reducing the sequelae associated with HTN
Following a rigorous and comprehensive search of the evidence since 2001 a total of 12 studies
were identified One study was a meta-analysis while the remaining eleven studies were
Randomized Control Trials Evidence across the studies supported the utilization of APNs and
tele-monitoring to reduce HTN amongst AA men aged 40 years and older
Rosswurm and Larrabeersquos framework was chosen to guide the EBPCP The setting will be
a medium size solo family practice office A purposive sample of 60 AA men will be recruited by
two APNs during a routine family practice visit encouraging participation in the intervention The
EBPCP will consist of a tailored culturally sensitive educational intervention incorporating tele-
monitoring by APNs The intervention will be measured using various instruments including BP
and weight via anthropometric measures exercise pattern (Lorig et al 1996) diet type and
frequency (ordinal scale) medication adherence (Moriskyrsquos scale) smoking and alcohol
consumption (self-reported on a nominal scale) and patient satisfaction (investigator-developed
open-ended questionnaire) These will be measured at baseline and again at one month three
months and six months Donabedienrsquos evaluation model will be used to evaluate the intervention
Problem Statement
The problem of interest for the proposed practice change is hypertension (HTN) HTN is
the number one silent killer among adults in the United States (US) According to the Centers for
Disease Control and Prevention [CDC] (2012) African Americans [AA] (444) have the highest
prevalence of HTN compared to Whites (326) and Mexican Americans (283) The World
Health Organization [WHO] (2011) attributes HTN as the leading cause of cardiovascular mortality
worldwide In 2008 the prevalence of HTN among adults aged 18 years and older was 68 million
(31) and has shown no improvement in the past decade Less than half of those with HTN have
their condition under control It affects one in three adults in the US and contributes to one out of
every seven deaths and nearly half of all cardiovascular disease--related deaths in the US In the
state of Ohio HTN is more prevalent among men (331) compared to women (304) when
considering races AAs have a higher prevalence (404) compared to whites (311) In 2010 the
related health care cost of HTN in the US was about $766 billion (CDC 2011) The American
Heart Association Institute of Medicine WHO and Healthy People 2020 aim to reduce the
prevalence of hypertension by assessing high risk factors providing education and eliminating
gaps in the treatment plan Although research on treatments is advancing disparities in HTN
exists among AAs which indicates a need for more evidence based research to close this widening
gap
Healthy People 2020 have included HTN reduction among its objectives The baseline rate for this
decade was 299 The target rate is projected to be 269 with an estimated 10 improvement
(Department of Health and Human Services 2012) This goal cannot be accomplished without turning the
focus onto the population group with the highest prevalence of HTN in the US which is largely constituted
by AA males aged 40 years and older AAs develop high blood pressure (BP) more often and at an earlier
age compared to whites and Mexican Americans (CDC 2012)
The American Heart Association (2012) describes HTN as an abnormal high measurement of the
force exerted on the arterial walls by the blood pumped from the heart Optimal blood pressure is less than
12080 mmHg HTN is defined as a consistent elevation of the systolic BP above 140 mmHg and a diastolic
BP above 90 mmHg Consequently when HTN is left untreated after a while sequelae can be detrimental
and multiple systems can be affected such as cardiovascular neurology renal ophthalmology
reproductive and respiratory High risk factors for high BP are advancing age obesity males AA heritage
family history of hypertension atherosclerosis diabetes smoking high-salt diet excessive alcohol
consumption and emotional stress (National Institute of Health 2012)
The possible interventions to encounter HTN are (1) The Dietary Approaches to Stop
Hypertension (DASH) eating plan DASH is a simple heart healthy diet that can help prevent or lower high
BP This diet is low in sodium cholesterol saturated and total fat and high in fruits and vegetables fiber
potassium and low-fat dairy products (2) Monitoring BP is important because high BP often has no
symptoms One way to improve BP is by tele-monitoring patients in the convenience of their homes
Interventions that use home BP tele-monitoring linked with patient feedback and medication titration can
enhance access and improve outcomes for adults with HTN (Bosworth 2011) (3) Education regarding
lifestyle modification such as eating a healthy diet maintaining a healthy weight calculating and
maintaining body mass index (BMI) within normal range engaging in moderate physical activity smoking
cessation limiting alcohol and medication adherence (4) Preventing and managing diabetes (5) Treating
high BP with medications and stressing the importance of medication adherence (CDC 2012)
The principle goal of treating HTN is to reduce the sequelae associated with HTN and to prevent
multiple system damage Although the recommended intervention varies and is dependent on the patientrsquos
age and severity of HTN experts believe that innovative tailored culturally sensitive educational
interventions via tele-monitoring are most effective in reducing high BP Based on these recommendations
we propose a six-month tailored culturally-sensitive educational intervention incorporating tele-monitoring
by APNs employed by a private practice The educational intervention will include diet management
engaging in moderate physical activity weight control medication adherence and assessment of lifestyle
changes (smoking cessation and limiting alcohol consumption) in comparison to standard educational
intervention of blood pressure management by APNs The proposed practice change delivered over a six-
month time period will be guided by asking clinical questions in PICOT format [P population of interest I
intervention or issue of interest C comparison of interest O outcome expected and T time for the
intervention to achieve the outcome] (Melnyk amp Fineout-Overholt 2011)
The purpose of this EBPCP delivered by APNs is to provide adequate management of HTN
resulting in decreased HTN among AA males aged 40 years and older Based on these recommendations
our PICOT question is In hypertensive AA males aged gt 40 years (P) what is the efficacy of a tailored
culturally-sensitive educational intervention via tele-monitoring by APNs employed by private practice (I) in
comparison to standard educational intervention of blood pressure management by APNs (C) in reducing
blood pressure readings within normal range of lt 12080 mmHg (O) over a six month period (T) (see
Appendix A)
Planning the Practice Change Team
There are several disciplines that must be included in planning this practice change The APNs
physician staff nurses nursing assistants billing and clerical staff all need to have input into the best way
to integrate the proposed practice change into the patientrsquos plan of care By including all levels of staff in
the planning the best methods of implementing and monitoring alternate BP measurements can be
determined
The key informants in implementing this practice change will include all levels of staff within the
primary care practice The APNrsquos salary which is approximately $92000 per year will be prorated for one
dayweek to oversee the proposed practice change from the onset to conclusion and to maintain the
integrity of data collection and data analysisinterpretation The APN and physician need to give guidance
on clinically acceptable BP readings and pharmacological management of HTN The staff nurses need to
provide information on the techniques on BP monitoring as well as support staff teaching Clerical staff and
nursing assistants will play an important role by providing feedback regarding the charting system and the
ease of being able to gather and provide information about BP readings from the patients to the APN
Finally the billing staff needs to provide information about the proper billing for in office versus in home BP
monitoring The practice change team will work once per week to coordinate the change process The
setting for the proposed practice change will be a medium size solo family practice office in a moderate size
city in the Midwest with a large or rapidly growing population of AAs
No participants from outside agencies will be involved in the implementation of this practice
change The monitoring of BP will be done by APNs The practice staff will monitor all interventions
Critical Appraisal of Evidence
Multiple sources of evidence have contributed to the development of the proposed evidence based
practice change These sources include one Cochrane meta-analyses review and eleven randomized
controlled trials The collection of evidence was obtained following an extensive literature review using the
following databases Cochrane CINAHL PubMed MEDLINE and PsycINFO The literature search was
derived from the following key words hypertension blood pressure usual care for hypertension tele-
monitoring telemedicine nurse practitioner advanced practice nurse and African Americans
Articles were selected for utilization based upon their applicability to the reduction of HTN in AAs Eighty
articles were reviewed however a majority was eliminated because they were greater than 12 years old
the sample size was too small they did not completely fit the aforementioned criteria for the proposed
practice change or they were lower levels of evidence The synthesis of evidence and strength of the
evidence tables are provided in Appendix B and C
Jaana Pare and Sicotte (2007) conducted a meta-analysis to investigate the efficacy of home
blood pressure monitoring via tele-monitoring towards the reduction of HTN Jaana Pare and Sicottes
(2007) findings indicated that the control of BP is better achieved when measured at home as opposed to in
clinical settings In addition to a reduction of HTN the utilization of home BP monitoring was also shown to
be beneficial in the identification of lsquoWhite coat syndromersquo Identification of lsquoWhite coat syndromersquo can
prevent over treatment of patients with anti-hypertensive medications Artinian Washington and Templin
(2001) performed a randomized control trial (RCT) to determine if the addition of tele-monitoring to the
usual care for BP management would reduce BP more than in those who just receive the usual care
Artinian (2001) concluded that patientsrsquo who received tele-monitoring in addition to the usual care
yielded the most significant reduction in BP over the course of the clinical trial In 2007 Artinian Flack
Nordstrom Hockman Washington Jen and Fathy built off the previously mentioned study performing a
RCT on AAs with HTN This study was comparing patients who received usual care to those patients who
received tele-monitoring in addition to usual care for BP management Artinian et al (2007) concluded that
those patients who received the usual care and tele-monitoring experienced a more significant decrease in
BP than the control group
Continuing to evaluate usual care McManus Mant Bray Holder Jones Greenfield Kaambwa
Bryan Little Williams and Hobbs (2010) performed a RCT on 527 hypertensive adults in England The
study was comparing the usual care provided by family physicians to patient self-management via tele-
monitoring The study concluded that over a monitoring period of one year those who received the self-
management intervention via tele-monitoring realized a greater reduction in BP when compared to those
with usual care Parati Omboni Albini Piantoni Giuliano Revera Illyes and Mancia (2009) performed a
RCT to compare patients who received usual care for HTN management to those patients who utilized
tele-monitoring for HTN management Parati et al (2009) concluded that those individuals in which tele-
monitoring were the main intervention experienced an overall greater reduction in HTN than those with
usual care
Brennan Spettell Villagra Ofili McMahill-Walraven Lowy Daniels Quarshie and Mayberry (2010)
performed a RCT on 954 hypertensive AA males This study compared the management of HTN by a
telephonic nurse and in home BP monitoring against those with just in home BP monitoring Brennan et al
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

[AA] (444) have the highest prevalence of hypertension (HTN) when compared to Whites
(326) and Mexican Americans (283) The research team proposed a culturally-sensitive
educational intervention via tele-monitoring delivered by Advance Practice Nurses (APNs) in a
private family practice setting The goal is to reduce blood pressure (BP) readings in AA males
aged gt 40 years to within normal range of lt 12080 mmHg over a six-month period Stakeholders
include patients family members physician APNs and private practice staff Resistance may
come from staff and APNs because of additional work responsibilities in managing patients
Strengths of change include decreasing BP and reducing the sequelae associated with HTN
Following a rigorous and comprehensive search of the evidence since 2001 a total of 12 studies
were identified One study was a meta-analysis while the remaining eleven studies were
Randomized Control Trials Evidence across the studies supported the utilization of APNs and
tele-monitoring to reduce HTN amongst AA men aged 40 years and older
Rosswurm and Larrabeersquos framework was chosen to guide the EBPCP The setting will be
a medium size solo family practice office A purposive sample of 60 AA men will be recruited by
two APNs during a routine family practice visit encouraging participation in the intervention The
EBPCP will consist of a tailored culturally sensitive educational intervention incorporating tele-
monitoring by APNs The intervention will be measured using various instruments including BP
and weight via anthropometric measures exercise pattern (Lorig et al 1996) diet type and
frequency (ordinal scale) medication adherence (Moriskyrsquos scale) smoking and alcohol
consumption (self-reported on a nominal scale) and patient satisfaction (investigator-developed
open-ended questionnaire) These will be measured at baseline and again at one month three
months and six months Donabedienrsquos evaluation model will be used to evaluate the intervention
Problem Statement
The problem of interest for the proposed practice change is hypertension (HTN) HTN is
the number one silent killer among adults in the United States (US) According to the Centers for
Disease Control and Prevention [CDC] (2012) African Americans [AA] (444) have the highest
prevalence of HTN compared to Whites (326) and Mexican Americans (283) The World
Health Organization [WHO] (2011) attributes HTN as the leading cause of cardiovascular mortality
worldwide In 2008 the prevalence of HTN among adults aged 18 years and older was 68 million
(31) and has shown no improvement in the past decade Less than half of those with HTN have
their condition under control It affects one in three adults in the US and contributes to one out of
every seven deaths and nearly half of all cardiovascular disease--related deaths in the US In the
state of Ohio HTN is more prevalent among men (331) compared to women (304) when
considering races AAs have a higher prevalence (404) compared to whites (311) In 2010 the
related health care cost of HTN in the US was about $766 billion (CDC 2011) The American
Heart Association Institute of Medicine WHO and Healthy People 2020 aim to reduce the
prevalence of hypertension by assessing high risk factors providing education and eliminating
gaps in the treatment plan Although research on treatments is advancing disparities in HTN
exists among AAs which indicates a need for more evidence based research to close this widening
gap
Healthy People 2020 have included HTN reduction among its objectives The baseline rate for this
decade was 299 The target rate is projected to be 269 with an estimated 10 improvement
(Department of Health and Human Services 2012) This goal cannot be accomplished without turning the
focus onto the population group with the highest prevalence of HTN in the US which is largely constituted
by AA males aged 40 years and older AAs develop high blood pressure (BP) more often and at an earlier
age compared to whites and Mexican Americans (CDC 2012)
The American Heart Association (2012) describes HTN as an abnormal high measurement of the
force exerted on the arterial walls by the blood pumped from the heart Optimal blood pressure is less than
12080 mmHg HTN is defined as a consistent elevation of the systolic BP above 140 mmHg and a diastolic
BP above 90 mmHg Consequently when HTN is left untreated after a while sequelae can be detrimental
and multiple systems can be affected such as cardiovascular neurology renal ophthalmology
reproductive and respiratory High risk factors for high BP are advancing age obesity males AA heritage
family history of hypertension atherosclerosis diabetes smoking high-salt diet excessive alcohol
consumption and emotional stress (National Institute of Health 2012)
The possible interventions to encounter HTN are (1) The Dietary Approaches to Stop
Hypertension (DASH) eating plan DASH is a simple heart healthy diet that can help prevent or lower high
BP This diet is low in sodium cholesterol saturated and total fat and high in fruits and vegetables fiber
potassium and low-fat dairy products (2) Monitoring BP is important because high BP often has no
symptoms One way to improve BP is by tele-monitoring patients in the convenience of their homes
Interventions that use home BP tele-monitoring linked with patient feedback and medication titration can
enhance access and improve outcomes for adults with HTN (Bosworth 2011) (3) Education regarding
lifestyle modification such as eating a healthy diet maintaining a healthy weight calculating and
maintaining body mass index (BMI) within normal range engaging in moderate physical activity smoking
cessation limiting alcohol and medication adherence (4) Preventing and managing diabetes (5) Treating
high BP with medications and stressing the importance of medication adherence (CDC 2012)
The principle goal of treating HTN is to reduce the sequelae associated with HTN and to prevent
multiple system damage Although the recommended intervention varies and is dependent on the patientrsquos
age and severity of HTN experts believe that innovative tailored culturally sensitive educational
interventions via tele-monitoring are most effective in reducing high BP Based on these recommendations
we propose a six-month tailored culturally-sensitive educational intervention incorporating tele-monitoring
by APNs employed by a private practice The educational intervention will include diet management
engaging in moderate physical activity weight control medication adherence and assessment of lifestyle
changes (smoking cessation and limiting alcohol consumption) in comparison to standard educational
intervention of blood pressure management by APNs The proposed practice change delivered over a six-
month time period will be guided by asking clinical questions in PICOT format [P population of interest I
intervention or issue of interest C comparison of interest O outcome expected and T time for the
intervention to achieve the outcome] (Melnyk amp Fineout-Overholt 2011)
The purpose of this EBPCP delivered by APNs is to provide adequate management of HTN
resulting in decreased HTN among AA males aged 40 years and older Based on these recommendations
our PICOT question is In hypertensive AA males aged gt 40 years (P) what is the efficacy of a tailored
culturally-sensitive educational intervention via tele-monitoring by APNs employed by private practice (I) in
comparison to standard educational intervention of blood pressure management by APNs (C) in reducing
blood pressure readings within normal range of lt 12080 mmHg (O) over a six month period (T) (see
Appendix A)
Planning the Practice Change Team
There are several disciplines that must be included in planning this practice change The APNs
physician staff nurses nursing assistants billing and clerical staff all need to have input into the best way
to integrate the proposed practice change into the patientrsquos plan of care By including all levels of staff in
the planning the best methods of implementing and monitoring alternate BP measurements can be
determined
The key informants in implementing this practice change will include all levels of staff within the
primary care practice The APNrsquos salary which is approximately $92000 per year will be prorated for one
dayweek to oversee the proposed practice change from the onset to conclusion and to maintain the
integrity of data collection and data analysisinterpretation The APN and physician need to give guidance
on clinically acceptable BP readings and pharmacological management of HTN The staff nurses need to
provide information on the techniques on BP monitoring as well as support staff teaching Clerical staff and
nursing assistants will play an important role by providing feedback regarding the charting system and the
ease of being able to gather and provide information about BP readings from the patients to the APN
Finally the billing staff needs to provide information about the proper billing for in office versus in home BP
monitoring The practice change team will work once per week to coordinate the change process The
setting for the proposed practice change will be a medium size solo family practice office in a moderate size
city in the Midwest with a large or rapidly growing population of AAs
No participants from outside agencies will be involved in the implementation of this practice
change The monitoring of BP will be done by APNs The practice staff will monitor all interventions
Critical Appraisal of Evidence
Multiple sources of evidence have contributed to the development of the proposed evidence based
practice change These sources include one Cochrane meta-analyses review and eleven randomized
controlled trials The collection of evidence was obtained following an extensive literature review using the
following databases Cochrane CINAHL PubMed MEDLINE and PsycINFO The literature search was
derived from the following key words hypertension blood pressure usual care for hypertension tele-
monitoring telemedicine nurse practitioner advanced practice nurse and African Americans
Articles were selected for utilization based upon their applicability to the reduction of HTN in AAs Eighty
articles were reviewed however a majority was eliminated because they were greater than 12 years old
the sample size was too small they did not completely fit the aforementioned criteria for the proposed
practice change or they were lower levels of evidence The synthesis of evidence and strength of the
evidence tables are provided in Appendix B and C
Jaana Pare and Sicotte (2007) conducted a meta-analysis to investigate the efficacy of home
blood pressure monitoring via tele-monitoring towards the reduction of HTN Jaana Pare and Sicottes
(2007) findings indicated that the control of BP is better achieved when measured at home as opposed to in
clinical settings In addition to a reduction of HTN the utilization of home BP monitoring was also shown to
be beneficial in the identification of lsquoWhite coat syndromersquo Identification of lsquoWhite coat syndromersquo can
prevent over treatment of patients with anti-hypertensive medications Artinian Washington and Templin
(2001) performed a randomized control trial (RCT) to determine if the addition of tele-monitoring to the
usual care for BP management would reduce BP more than in those who just receive the usual care
Artinian (2001) concluded that patientsrsquo who received tele-monitoring in addition to the usual care
yielded the most significant reduction in BP over the course of the clinical trial In 2007 Artinian Flack
Nordstrom Hockman Washington Jen and Fathy built off the previously mentioned study performing a
RCT on AAs with HTN This study was comparing patients who received usual care to those patients who
received tele-monitoring in addition to usual care for BP management Artinian et al (2007) concluded that
those patients who received the usual care and tele-monitoring experienced a more significant decrease in
BP than the control group
Continuing to evaluate usual care McManus Mant Bray Holder Jones Greenfield Kaambwa
Bryan Little Williams and Hobbs (2010) performed a RCT on 527 hypertensive adults in England The
study was comparing the usual care provided by family physicians to patient self-management via tele-
monitoring The study concluded that over a monitoring period of one year those who received the self-
management intervention via tele-monitoring realized a greater reduction in BP when compared to those
with usual care Parati Omboni Albini Piantoni Giuliano Revera Illyes and Mancia (2009) performed a
RCT to compare patients who received usual care for HTN management to those patients who utilized
tele-monitoring for HTN management Parati et al (2009) concluded that those individuals in which tele-
monitoring were the main intervention experienced an overall greater reduction in HTN than those with
usual care
Brennan Spettell Villagra Ofili McMahill-Walraven Lowy Daniels Quarshie and Mayberry (2010)
performed a RCT on 954 hypertensive AA males This study compared the management of HTN by a
telephonic nurse and in home BP monitoring against those with just in home BP monitoring Brennan et al
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Abstract
According to the Centers for Disease Control and Prevention (2012) African Americans
[AA] (444) have the highest prevalence of hypertension (HTN) when compared to Whites
(326) and Mexican Americans (283) The research team proposed a culturally-sensitive
educational intervention via tele-monitoring delivered by Advance Practice Nurses (APNs) in a
private family practice setting The goal is to reduce blood pressure (BP) readings in AA males
aged gt 40 years to within normal range of lt 12080 mmHg over a six-month period Stakeholders
include patients family members physician APNs and private practice staff Resistance may
come from staff and APNs because of additional work responsibilities in managing patients
Strengths of change include decreasing BP and reducing the sequelae associated with HTN
Following a rigorous and comprehensive search of the evidence since 2001 a total of 12 studies
were identified One study was a meta-analysis while the remaining eleven studies were
Randomized Control Trials Evidence across the studies supported the utilization of APNs and
tele-monitoring to reduce HTN amongst AA men aged 40 years and older
Rosswurm and Larrabeersquos framework was chosen to guide the EBPCP The setting will be
a medium size solo family practice office A purposive sample of 60 AA men will be recruited by
two APNs during a routine family practice visit encouraging participation in the intervention The
EBPCP will consist of a tailored culturally sensitive educational intervention incorporating tele-
monitoring by APNs The intervention will be measured using various instruments including BP
and weight via anthropometric measures exercise pattern (Lorig et al 1996) diet type and
frequency (ordinal scale) medication adherence (Moriskyrsquos scale) smoking and alcohol
consumption (self-reported on a nominal scale) and patient satisfaction (investigator-developed
open-ended questionnaire) These will be measured at baseline and again at one month three
months and six months Donabedienrsquos evaluation model will be used to evaluate the intervention
Problem Statement
The problem of interest for the proposed practice change is hypertension (HTN) HTN is
the number one silent killer among adults in the United States (US) According to the Centers for
Disease Control and Prevention [CDC] (2012) African Americans [AA] (444) have the highest
prevalence of HTN compared to Whites (326) and Mexican Americans (283) The World
Health Organization [WHO] (2011) attributes HTN as the leading cause of cardiovascular mortality
worldwide In 2008 the prevalence of HTN among adults aged 18 years and older was 68 million
(31) and has shown no improvement in the past decade Less than half of those with HTN have
their condition under control It affects one in three adults in the US and contributes to one out of
every seven deaths and nearly half of all cardiovascular disease--related deaths in the US In the
state of Ohio HTN is more prevalent among men (331) compared to women (304) when
considering races AAs have a higher prevalence (404) compared to whites (311) In 2010 the
related health care cost of HTN in the US was about $766 billion (CDC 2011) The American
Heart Association Institute of Medicine WHO and Healthy People 2020 aim to reduce the
prevalence of hypertension by assessing high risk factors providing education and eliminating
gaps in the treatment plan Although research on treatments is advancing disparities in HTN
exists among AAs which indicates a need for more evidence based research to close this widening
gap
Healthy People 2020 have included HTN reduction among its objectives The baseline rate for this
decade was 299 The target rate is projected to be 269 with an estimated 10 improvement
(Department of Health and Human Services 2012) This goal cannot be accomplished without turning the
focus onto the population group with the highest prevalence of HTN in the US which is largely constituted
by AA males aged 40 years and older AAs develop high blood pressure (BP) more often and at an earlier
age compared to whites and Mexican Americans (CDC 2012)
The American Heart Association (2012) describes HTN as an abnormal high measurement of the
force exerted on the arterial walls by the blood pumped from the heart Optimal blood pressure is less than
12080 mmHg HTN is defined as a consistent elevation of the systolic BP above 140 mmHg and a diastolic
BP above 90 mmHg Consequently when HTN is left untreated after a while sequelae can be detrimental
and multiple systems can be affected such as cardiovascular neurology renal ophthalmology
reproductive and respiratory High risk factors for high BP are advancing age obesity males AA heritage
family history of hypertension atherosclerosis diabetes smoking high-salt diet excessive alcohol
consumption and emotional stress (National Institute of Health 2012)
The possible interventions to encounter HTN are (1) The Dietary Approaches to Stop
Hypertension (DASH) eating plan DASH is a simple heart healthy diet that can help prevent or lower high
BP This diet is low in sodium cholesterol saturated and total fat and high in fruits and vegetables fiber
potassium and low-fat dairy products (2) Monitoring BP is important because high BP often has no
symptoms One way to improve BP is by tele-monitoring patients in the convenience of their homes
Interventions that use home BP tele-monitoring linked with patient feedback and medication titration can
enhance access and improve outcomes for adults with HTN (Bosworth 2011) (3) Education regarding
lifestyle modification such as eating a healthy diet maintaining a healthy weight calculating and
maintaining body mass index (BMI) within normal range engaging in moderate physical activity smoking
cessation limiting alcohol and medication adherence (4) Preventing and managing diabetes (5) Treating
high BP with medications and stressing the importance of medication adherence (CDC 2012)
The principle goal of treating HTN is to reduce the sequelae associated with HTN and to prevent
multiple system damage Although the recommended intervention varies and is dependent on the patientrsquos
age and severity of HTN experts believe that innovative tailored culturally sensitive educational
interventions via tele-monitoring are most effective in reducing high BP Based on these recommendations
we propose a six-month tailored culturally-sensitive educational intervention incorporating tele-monitoring
by APNs employed by a private practice The educational intervention will include diet management
engaging in moderate physical activity weight control medication adherence and assessment of lifestyle
changes (smoking cessation and limiting alcohol consumption) in comparison to standard educational
intervention of blood pressure management by APNs The proposed practice change delivered over a six-
month time period will be guided by asking clinical questions in PICOT format [P population of interest I
intervention or issue of interest C comparison of interest O outcome expected and T time for the
intervention to achieve the outcome] (Melnyk amp Fineout-Overholt 2011)
The purpose of this EBPCP delivered by APNs is to provide adequate management of HTN
resulting in decreased HTN among AA males aged 40 years and older Based on these recommendations
our PICOT question is In hypertensive AA males aged gt 40 years (P) what is the efficacy of a tailored
culturally-sensitive educational intervention via tele-monitoring by APNs employed by private practice (I) in
comparison to standard educational intervention of blood pressure management by APNs (C) in reducing
blood pressure readings within normal range of lt 12080 mmHg (O) over a six month period (T) (see
Appendix A)
Planning the Practice Change Team
There are several disciplines that must be included in planning this practice change The APNs
physician staff nurses nursing assistants billing and clerical staff all need to have input into the best way
to integrate the proposed practice change into the patientrsquos plan of care By including all levels of staff in
the planning the best methods of implementing and monitoring alternate BP measurements can be
determined
The key informants in implementing this practice change will include all levels of staff within the
primary care practice The APNrsquos salary which is approximately $92000 per year will be prorated for one
dayweek to oversee the proposed practice change from the onset to conclusion and to maintain the
integrity of data collection and data analysisinterpretation The APN and physician need to give guidance
on clinically acceptable BP readings and pharmacological management of HTN The staff nurses need to
provide information on the techniques on BP monitoring as well as support staff teaching Clerical staff and
nursing assistants will play an important role by providing feedback regarding the charting system and the
ease of being able to gather and provide information about BP readings from the patients to the APN
Finally the billing staff needs to provide information about the proper billing for in office versus in home BP
monitoring The practice change team will work once per week to coordinate the change process The
setting for the proposed practice change will be a medium size solo family practice office in a moderate size
city in the Midwest with a large or rapidly growing population of AAs
No participants from outside agencies will be involved in the implementation of this practice
change The monitoring of BP will be done by APNs The practice staff will monitor all interventions
Critical Appraisal of Evidence
Multiple sources of evidence have contributed to the development of the proposed evidence based
practice change These sources include one Cochrane meta-analyses review and eleven randomized
controlled trials The collection of evidence was obtained following an extensive literature review using the
following databases Cochrane CINAHL PubMed MEDLINE and PsycINFO The literature search was
derived from the following key words hypertension blood pressure usual care for hypertension tele-
monitoring telemedicine nurse practitioner advanced practice nurse and African Americans
Articles were selected for utilization based upon their applicability to the reduction of HTN in AAs Eighty
articles were reviewed however a majority was eliminated because they were greater than 12 years old
the sample size was too small they did not completely fit the aforementioned criteria for the proposed
practice change or they were lower levels of evidence The synthesis of evidence and strength of the
evidence tables are provided in Appendix B and C
Jaana Pare and Sicotte (2007) conducted a meta-analysis to investigate the efficacy of home
blood pressure monitoring via tele-monitoring towards the reduction of HTN Jaana Pare and Sicottes
(2007) findings indicated that the control of BP is better achieved when measured at home as opposed to in
clinical settings In addition to a reduction of HTN the utilization of home BP monitoring was also shown to
be beneficial in the identification of lsquoWhite coat syndromersquo Identification of lsquoWhite coat syndromersquo can
prevent over treatment of patients with anti-hypertensive medications Artinian Washington and Templin
(2001) performed a randomized control trial (RCT) to determine if the addition of tele-monitoring to the
usual care for BP management would reduce BP more than in those who just receive the usual care
Artinian (2001) concluded that patientsrsquo who received tele-monitoring in addition to the usual care
yielded the most significant reduction in BP over the course of the clinical trial In 2007 Artinian Flack
Nordstrom Hockman Washington Jen and Fathy built off the previously mentioned study performing a
RCT on AAs with HTN This study was comparing patients who received usual care to those patients who
received tele-monitoring in addition to usual care for BP management Artinian et al (2007) concluded that
those patients who received the usual care and tele-monitoring experienced a more significant decrease in
BP than the control group
Continuing to evaluate usual care McManus Mant Bray Holder Jones Greenfield Kaambwa
Bryan Little Williams and Hobbs (2010) performed a RCT on 527 hypertensive adults in England The
study was comparing the usual care provided by family physicians to patient self-management via tele-
monitoring The study concluded that over a monitoring period of one year those who received the self-
management intervention via tele-monitoring realized a greater reduction in BP when compared to those
with usual care Parati Omboni Albini Piantoni Giuliano Revera Illyes and Mancia (2009) performed a
RCT to compare patients who received usual care for HTN management to those patients who utilized
tele-monitoring for HTN management Parati et al (2009) concluded that those individuals in which tele-
monitoring were the main intervention experienced an overall greater reduction in HTN than those with
usual care
Brennan Spettell Villagra Ofili McMahill-Walraven Lowy Daniels Quarshie and Mayberry (2010)
performed a RCT on 954 hypertensive AA males This study compared the management of HTN by a
telephonic nurse and in home BP monitoring against those with just in home BP monitoring Brennan et al
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Problem Statement
The problem of interest for the proposed practice change is hypertension (HTN) HTN is
the number one silent killer among adults in the United States (US) According to the Centers for
Disease Control and Prevention [CDC] (2012) African Americans [AA] (444) have the highest
prevalence of HTN compared to Whites (326) and Mexican Americans (283) The World
Health Organization [WHO] (2011) attributes HTN as the leading cause of cardiovascular mortality
worldwide In 2008 the prevalence of HTN among adults aged 18 years and older was 68 million
(31) and has shown no improvement in the past decade Less than half of those with HTN have
their condition under control It affects one in three adults in the US and contributes to one out of
every seven deaths and nearly half of all cardiovascular disease--related deaths in the US In the
state of Ohio HTN is more prevalent among men (331) compared to women (304) when
considering races AAs have a higher prevalence (404) compared to whites (311) In 2010 the
related health care cost of HTN in the US was about $766 billion (CDC 2011) The American
Heart Association Institute of Medicine WHO and Healthy People 2020 aim to reduce the
prevalence of hypertension by assessing high risk factors providing education and eliminating
gaps in the treatment plan Although research on treatments is advancing disparities in HTN
exists among AAs which indicates a need for more evidence based research to close this widening
gap
Healthy People 2020 have included HTN reduction among its objectives The baseline rate for this
decade was 299 The target rate is projected to be 269 with an estimated 10 improvement
(Department of Health and Human Services 2012) This goal cannot be accomplished without turning the
focus onto the population group with the highest prevalence of HTN in the US which is largely constituted
by AA males aged 40 years and older AAs develop high blood pressure (BP) more often and at an earlier
age compared to whites and Mexican Americans (CDC 2012)
The American Heart Association (2012) describes HTN as an abnormal high measurement of the
force exerted on the arterial walls by the blood pumped from the heart Optimal blood pressure is less than
12080 mmHg HTN is defined as a consistent elevation of the systolic BP above 140 mmHg and a diastolic
BP above 90 mmHg Consequently when HTN is left untreated after a while sequelae can be detrimental
and multiple systems can be affected such as cardiovascular neurology renal ophthalmology
reproductive and respiratory High risk factors for high BP are advancing age obesity males AA heritage
family history of hypertension atherosclerosis diabetes smoking high-salt diet excessive alcohol
consumption and emotional stress (National Institute of Health 2012)
The possible interventions to encounter HTN are (1) The Dietary Approaches to Stop
Hypertension (DASH) eating plan DASH is a simple heart healthy diet that can help prevent or lower high
BP This diet is low in sodium cholesterol saturated and total fat and high in fruits and vegetables fiber
potassium and low-fat dairy products (2) Monitoring BP is important because high BP often has no
symptoms One way to improve BP is by tele-monitoring patients in the convenience of their homes
Interventions that use home BP tele-monitoring linked with patient feedback and medication titration can
enhance access and improve outcomes for adults with HTN (Bosworth 2011) (3) Education regarding
lifestyle modification such as eating a healthy diet maintaining a healthy weight calculating and
maintaining body mass index (BMI) within normal range engaging in moderate physical activity smoking
cessation limiting alcohol and medication adherence (4) Preventing and managing diabetes (5) Treating
high BP with medications and stressing the importance of medication adherence (CDC 2012)
The principle goal of treating HTN is to reduce the sequelae associated with HTN and to prevent
multiple system damage Although the recommended intervention varies and is dependent on the patientrsquos
age and severity of HTN experts believe that innovative tailored culturally sensitive educational
interventions via tele-monitoring are most effective in reducing high BP Based on these recommendations
we propose a six-month tailored culturally-sensitive educational intervention incorporating tele-monitoring
by APNs employed by a private practice The educational intervention will include diet management
engaging in moderate physical activity weight control medication adherence and assessment of lifestyle
changes (smoking cessation and limiting alcohol consumption) in comparison to standard educational
intervention of blood pressure management by APNs The proposed practice change delivered over a six-
month time period will be guided by asking clinical questions in PICOT format [P population of interest I
intervention or issue of interest C comparison of interest O outcome expected and T time for the
intervention to achieve the outcome] (Melnyk amp Fineout-Overholt 2011)
The purpose of this EBPCP delivered by APNs is to provide adequate management of HTN
resulting in decreased HTN among AA males aged 40 years and older Based on these recommendations
our PICOT question is In hypertensive AA males aged gt 40 years (P) what is the efficacy of a tailored
culturally-sensitive educational intervention via tele-monitoring by APNs employed by private practice (I) in
comparison to standard educational intervention of blood pressure management by APNs (C) in reducing
blood pressure readings within normal range of lt 12080 mmHg (O) over a six month period (T) (see
Appendix A)
Planning the Practice Change Team
There are several disciplines that must be included in planning this practice change The APNs
physician staff nurses nursing assistants billing and clerical staff all need to have input into the best way
to integrate the proposed practice change into the patientrsquos plan of care By including all levels of staff in
the planning the best methods of implementing and monitoring alternate BP measurements can be
determined
The key informants in implementing this practice change will include all levels of staff within the
primary care practice The APNrsquos salary which is approximately $92000 per year will be prorated for one
dayweek to oversee the proposed practice change from the onset to conclusion and to maintain the
integrity of data collection and data analysisinterpretation The APN and physician need to give guidance
on clinically acceptable BP readings and pharmacological management of HTN The staff nurses need to
provide information on the techniques on BP monitoring as well as support staff teaching Clerical staff and
nursing assistants will play an important role by providing feedback regarding the charting system and the
ease of being able to gather and provide information about BP readings from the patients to the APN
Finally the billing staff needs to provide information about the proper billing for in office versus in home BP
monitoring The practice change team will work once per week to coordinate the change process The
setting for the proposed practice change will be a medium size solo family practice office in a moderate size
city in the Midwest with a large or rapidly growing population of AAs
No participants from outside agencies will be involved in the implementation of this practice
change The monitoring of BP will be done by APNs The practice staff will monitor all interventions
Critical Appraisal of Evidence
Multiple sources of evidence have contributed to the development of the proposed evidence based
practice change These sources include one Cochrane meta-analyses review and eleven randomized
controlled trials The collection of evidence was obtained following an extensive literature review using the
following databases Cochrane CINAHL PubMed MEDLINE and PsycINFO The literature search was
derived from the following key words hypertension blood pressure usual care for hypertension tele-
monitoring telemedicine nurse practitioner advanced practice nurse and African Americans
Articles were selected for utilization based upon their applicability to the reduction of HTN in AAs Eighty
articles were reviewed however a majority was eliminated because they were greater than 12 years old
the sample size was too small they did not completely fit the aforementioned criteria for the proposed
practice change or they were lower levels of evidence The synthesis of evidence and strength of the
evidence tables are provided in Appendix B and C
Jaana Pare and Sicotte (2007) conducted a meta-analysis to investigate the efficacy of home
blood pressure monitoring via tele-monitoring towards the reduction of HTN Jaana Pare and Sicottes
(2007) findings indicated that the control of BP is better achieved when measured at home as opposed to in
clinical settings In addition to a reduction of HTN the utilization of home BP monitoring was also shown to
be beneficial in the identification of lsquoWhite coat syndromersquo Identification of lsquoWhite coat syndromersquo can
prevent over treatment of patients with anti-hypertensive medications Artinian Washington and Templin
(2001) performed a randomized control trial (RCT) to determine if the addition of tele-monitoring to the
usual care for BP management would reduce BP more than in those who just receive the usual care
Artinian (2001) concluded that patientsrsquo who received tele-monitoring in addition to the usual care
yielded the most significant reduction in BP over the course of the clinical trial In 2007 Artinian Flack
Nordstrom Hockman Washington Jen and Fathy built off the previously mentioned study performing a
RCT on AAs with HTN This study was comparing patients who received usual care to those patients who
received tele-monitoring in addition to usual care for BP management Artinian et al (2007) concluded that
those patients who received the usual care and tele-monitoring experienced a more significant decrease in
BP than the control group
Continuing to evaluate usual care McManus Mant Bray Holder Jones Greenfield Kaambwa
Bryan Little Williams and Hobbs (2010) performed a RCT on 527 hypertensive adults in England The
study was comparing the usual care provided by family physicians to patient self-management via tele-
monitoring The study concluded that over a monitoring period of one year those who received the self-
management intervention via tele-monitoring realized a greater reduction in BP when compared to those
with usual care Parati Omboni Albini Piantoni Giuliano Revera Illyes and Mancia (2009) performed a
RCT to compare patients who received usual care for HTN management to those patients who utilized
tele-monitoring for HTN management Parati et al (2009) concluded that those individuals in which tele-
monitoring were the main intervention experienced an overall greater reduction in HTN than those with
usual care
Brennan Spettell Villagra Ofili McMahill-Walraven Lowy Daniels Quarshie and Mayberry (2010)
performed a RCT on 954 hypertensive AA males This study compared the management of HTN by a
telephonic nurse and in home BP monitoring against those with just in home BP monitoring Brennan et al
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
by AA males aged 40 years and older AAs develop high blood pressure (BP) more often and at an earlier
age compared to whites and Mexican Americans (CDC 2012)
The American Heart Association (2012) describes HTN as an abnormal high measurement of the
force exerted on the arterial walls by the blood pumped from the heart Optimal blood pressure is less than
12080 mmHg HTN is defined as a consistent elevation of the systolic BP above 140 mmHg and a diastolic
BP above 90 mmHg Consequently when HTN is left untreated after a while sequelae can be detrimental
and multiple systems can be affected such as cardiovascular neurology renal ophthalmology
reproductive and respiratory High risk factors for high BP are advancing age obesity males AA heritage
family history of hypertension atherosclerosis diabetes smoking high-salt diet excessive alcohol
consumption and emotional stress (National Institute of Health 2012)
The possible interventions to encounter HTN are (1) The Dietary Approaches to Stop
Hypertension (DASH) eating plan DASH is a simple heart healthy diet that can help prevent or lower high
BP This diet is low in sodium cholesterol saturated and total fat and high in fruits and vegetables fiber
potassium and low-fat dairy products (2) Monitoring BP is important because high BP often has no
symptoms One way to improve BP is by tele-monitoring patients in the convenience of their homes
Interventions that use home BP tele-monitoring linked with patient feedback and medication titration can
enhance access and improve outcomes for adults with HTN (Bosworth 2011) (3) Education regarding
lifestyle modification such as eating a healthy diet maintaining a healthy weight calculating and
maintaining body mass index (BMI) within normal range engaging in moderate physical activity smoking
cessation limiting alcohol and medication adherence (4) Preventing and managing diabetes (5) Treating
high BP with medications and stressing the importance of medication adherence (CDC 2012)
The principle goal of treating HTN is to reduce the sequelae associated with HTN and to prevent
multiple system damage Although the recommended intervention varies and is dependent on the patientrsquos
age and severity of HTN experts believe that innovative tailored culturally sensitive educational
interventions via tele-monitoring are most effective in reducing high BP Based on these recommendations
we propose a six-month tailored culturally-sensitive educational intervention incorporating tele-monitoring
by APNs employed by a private practice The educational intervention will include diet management
engaging in moderate physical activity weight control medication adherence and assessment of lifestyle
changes (smoking cessation and limiting alcohol consumption) in comparison to standard educational
intervention of blood pressure management by APNs The proposed practice change delivered over a six-
month time period will be guided by asking clinical questions in PICOT format [P population of interest I
intervention or issue of interest C comparison of interest O outcome expected and T time for the
intervention to achieve the outcome] (Melnyk amp Fineout-Overholt 2011)
The purpose of this EBPCP delivered by APNs is to provide adequate management of HTN
resulting in decreased HTN among AA males aged 40 years and older Based on these recommendations
our PICOT question is In hypertensive AA males aged gt 40 years (P) what is the efficacy of a tailored
culturally-sensitive educational intervention via tele-monitoring by APNs employed by private practice (I) in
comparison to standard educational intervention of blood pressure management by APNs (C) in reducing
blood pressure readings within normal range of lt 12080 mmHg (O) over a six month period (T) (see
Appendix A)
Planning the Practice Change Team
There are several disciplines that must be included in planning this practice change The APNs
physician staff nurses nursing assistants billing and clerical staff all need to have input into the best way
to integrate the proposed practice change into the patientrsquos plan of care By including all levels of staff in
the planning the best methods of implementing and monitoring alternate BP measurements can be
determined
The key informants in implementing this practice change will include all levels of staff within the
primary care practice The APNrsquos salary which is approximately $92000 per year will be prorated for one
dayweek to oversee the proposed practice change from the onset to conclusion and to maintain the
integrity of data collection and data analysisinterpretation The APN and physician need to give guidance
on clinically acceptable BP readings and pharmacological management of HTN The staff nurses need to
provide information on the techniques on BP monitoring as well as support staff teaching Clerical staff and
nursing assistants will play an important role by providing feedback regarding the charting system and the
ease of being able to gather and provide information about BP readings from the patients to the APN
Finally the billing staff needs to provide information about the proper billing for in office versus in home BP
monitoring The practice change team will work once per week to coordinate the change process The
setting for the proposed practice change will be a medium size solo family practice office in a moderate size
city in the Midwest with a large or rapidly growing population of AAs
No participants from outside agencies will be involved in the implementation of this practice
change The monitoring of BP will be done by APNs The practice staff will monitor all interventions
Critical Appraisal of Evidence
Multiple sources of evidence have contributed to the development of the proposed evidence based
practice change These sources include one Cochrane meta-analyses review and eleven randomized
controlled trials The collection of evidence was obtained following an extensive literature review using the
following databases Cochrane CINAHL PubMed MEDLINE and PsycINFO The literature search was
derived from the following key words hypertension blood pressure usual care for hypertension tele-
monitoring telemedicine nurse practitioner advanced practice nurse and African Americans
Articles were selected for utilization based upon their applicability to the reduction of HTN in AAs Eighty
articles were reviewed however a majority was eliminated because they were greater than 12 years old
the sample size was too small they did not completely fit the aforementioned criteria for the proposed
practice change or they were lower levels of evidence The synthesis of evidence and strength of the
evidence tables are provided in Appendix B and C
Jaana Pare and Sicotte (2007) conducted a meta-analysis to investigate the efficacy of home
blood pressure monitoring via tele-monitoring towards the reduction of HTN Jaana Pare and Sicottes
(2007) findings indicated that the control of BP is better achieved when measured at home as opposed to in
clinical settings In addition to a reduction of HTN the utilization of home BP monitoring was also shown to
be beneficial in the identification of lsquoWhite coat syndromersquo Identification of lsquoWhite coat syndromersquo can
prevent over treatment of patients with anti-hypertensive medications Artinian Washington and Templin
(2001) performed a randomized control trial (RCT) to determine if the addition of tele-monitoring to the
usual care for BP management would reduce BP more than in those who just receive the usual care
Artinian (2001) concluded that patientsrsquo who received tele-monitoring in addition to the usual care
yielded the most significant reduction in BP over the course of the clinical trial In 2007 Artinian Flack
Nordstrom Hockman Washington Jen and Fathy built off the previously mentioned study performing a
RCT on AAs with HTN This study was comparing patients who received usual care to those patients who
received tele-monitoring in addition to usual care for BP management Artinian et al (2007) concluded that
those patients who received the usual care and tele-monitoring experienced a more significant decrease in
BP than the control group
Continuing to evaluate usual care McManus Mant Bray Holder Jones Greenfield Kaambwa
Bryan Little Williams and Hobbs (2010) performed a RCT on 527 hypertensive adults in England The
study was comparing the usual care provided by family physicians to patient self-management via tele-
monitoring The study concluded that over a monitoring period of one year those who received the self-
management intervention via tele-monitoring realized a greater reduction in BP when compared to those
with usual care Parati Omboni Albini Piantoni Giuliano Revera Illyes and Mancia (2009) performed a
RCT to compare patients who received usual care for HTN management to those patients who utilized
tele-monitoring for HTN management Parati et al (2009) concluded that those individuals in which tele-
monitoring were the main intervention experienced an overall greater reduction in HTN than those with
usual care
Brennan Spettell Villagra Ofili McMahill-Walraven Lowy Daniels Quarshie and Mayberry (2010)
performed a RCT on 954 hypertensive AA males This study compared the management of HTN by a
telephonic nurse and in home BP monitoring against those with just in home BP monitoring Brennan et al
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal

exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

The only confidence interval (CI) reported was in the change in creatinine serum The relative hazard ratio associated with assignment to more intensive versus less intensive was 063 (hazard ratio 95 CI=036-111
This randomized clinical trial compared the effect of a lessintensive intervention to a more intensive intervention to improve HTN in AAs
At 36 months the mean SBPDBP change from baseline was -75-101 mm Hg for less intensive group (p=001 and 005 for between-group differences in SBP and DBP respectively)

control group Limitations design adopted does not allow us to discriminate the role played by HBPM per se and by HBPM combined with teletransmission facilities in obtaining a greater rate of BP control
patient to stimulate adherence to measurement schedule whenever appropriate Self-monitored BP values were regularly transmitted to a referral centre where data were checked and stored in a digital database Values exceeding upper and lower predefined arbitrary safety thresholds (180110 and 10060 mmHg respectively) triggered an alarm on the basis of which a dedicated trained nurse called the patient at home to check hisher clinical status and the possibility of artefactual measurements

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
we propose a six-month tailored culturally-sensitive educational intervention incorporating tele-monitoring
by APNs employed by a private practice The educational intervention will include diet management
engaging in moderate physical activity weight control medication adherence and assessment of lifestyle
changes (smoking cessation and limiting alcohol consumption) in comparison to standard educational
intervention of blood pressure management by APNs The proposed practice change delivered over a six-
month time period will be guided by asking clinical questions in PICOT format [P population of interest I
intervention or issue of interest C comparison of interest O outcome expected and T time for the
intervention to achieve the outcome] (Melnyk amp Fineout-Overholt 2011)
The purpose of this EBPCP delivered by APNs is to provide adequate management of HTN
resulting in decreased HTN among AA males aged 40 years and older Based on these recommendations
our PICOT question is In hypertensive AA males aged gt 40 years (P) what is the efficacy of a tailored
culturally-sensitive educational intervention via tele-monitoring by APNs employed by private practice (I) in
comparison to standard educational intervention of blood pressure management by APNs (C) in reducing
blood pressure readings within normal range of lt 12080 mmHg (O) over a six month period (T) (see
Appendix A)
Planning the Practice Change Team
There are several disciplines that must be included in planning this practice change The APNs
physician staff nurses nursing assistants billing and clerical staff all need to have input into the best way
to integrate the proposed practice change into the patientrsquos plan of care By including all levels of staff in
the planning the best methods of implementing and monitoring alternate BP measurements can be
determined
The key informants in implementing this practice change will include all levels of staff within the
primary care practice The APNrsquos salary which is approximately $92000 per year will be prorated for one
dayweek to oversee the proposed practice change from the onset to conclusion and to maintain the
integrity of data collection and data analysisinterpretation The APN and physician need to give guidance
on clinically acceptable BP readings and pharmacological management of HTN The staff nurses need to
provide information on the techniques on BP monitoring as well as support staff teaching Clerical staff and
nursing assistants will play an important role by providing feedback regarding the charting system and the
ease of being able to gather and provide information about BP readings from the patients to the APN
Finally the billing staff needs to provide information about the proper billing for in office versus in home BP
monitoring The practice change team will work once per week to coordinate the change process The
setting for the proposed practice change will be a medium size solo family practice office in a moderate size
city in the Midwest with a large or rapidly growing population of AAs
No participants from outside agencies will be involved in the implementation of this practice
change The monitoring of BP will be done by APNs The practice staff will monitor all interventions
Critical Appraisal of Evidence
Multiple sources of evidence have contributed to the development of the proposed evidence based
practice change These sources include one Cochrane meta-analyses review and eleven randomized
controlled trials The collection of evidence was obtained following an extensive literature review using the
following databases Cochrane CINAHL PubMed MEDLINE and PsycINFO The literature search was
derived from the following key words hypertension blood pressure usual care for hypertension tele-
monitoring telemedicine nurse practitioner advanced practice nurse and African Americans
Articles were selected for utilization based upon their applicability to the reduction of HTN in AAs Eighty
articles were reviewed however a majority was eliminated because they were greater than 12 years old
the sample size was too small they did not completely fit the aforementioned criteria for the proposed
practice change or they were lower levels of evidence The synthesis of evidence and strength of the
evidence tables are provided in Appendix B and C
Jaana Pare and Sicotte (2007) conducted a meta-analysis to investigate the efficacy of home
blood pressure monitoring via tele-monitoring towards the reduction of HTN Jaana Pare and Sicottes
(2007) findings indicated that the control of BP is better achieved when measured at home as opposed to in
clinical settings In addition to a reduction of HTN the utilization of home BP monitoring was also shown to
be beneficial in the identification of lsquoWhite coat syndromersquo Identification of lsquoWhite coat syndromersquo can
prevent over treatment of patients with anti-hypertensive medications Artinian Washington and Templin
(2001) performed a randomized control trial (RCT) to determine if the addition of tele-monitoring to the
usual care for BP management would reduce BP more than in those who just receive the usual care
Artinian (2001) concluded that patientsrsquo who received tele-monitoring in addition to the usual care
yielded the most significant reduction in BP over the course of the clinical trial In 2007 Artinian Flack
Nordstrom Hockman Washington Jen and Fathy built off the previously mentioned study performing a
RCT on AAs with HTN This study was comparing patients who received usual care to those patients who
received tele-monitoring in addition to usual care for BP management Artinian et al (2007) concluded that
those patients who received the usual care and tele-monitoring experienced a more significant decrease in
BP than the control group
Continuing to evaluate usual care McManus Mant Bray Holder Jones Greenfield Kaambwa
Bryan Little Williams and Hobbs (2010) performed a RCT on 527 hypertensive adults in England The
study was comparing the usual care provided by family physicians to patient self-management via tele-
monitoring The study concluded that over a monitoring period of one year those who received the self-
management intervention via tele-monitoring realized a greater reduction in BP when compared to those
with usual care Parati Omboni Albini Piantoni Giuliano Revera Illyes and Mancia (2009) performed a
RCT to compare patients who received usual care for HTN management to those patients who utilized
tele-monitoring for HTN management Parati et al (2009) concluded that those individuals in which tele-
monitoring were the main intervention experienced an overall greater reduction in HTN than those with
usual care
Brennan Spettell Villagra Ofili McMahill-Walraven Lowy Daniels Quarshie and Mayberry (2010)
performed a RCT on 954 hypertensive AA males This study compared the management of HTN by a
telephonic nurse and in home BP monitoring against those with just in home BP monitoring Brennan et al
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The
Strengthswas determined by ABP monitoring which provides BP values devoid of inconveniences such as the white-coat effect the advantage of combining self-measurement of BP at home with data teletransmission is supported by two additional findings

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
on clinically acceptable BP readings and pharmacological management of HTN The staff nurses need to
provide information on the techniques on BP monitoring as well as support staff teaching Clerical staff and
nursing assistants will play an important role by providing feedback regarding the charting system and the
ease of being able to gather and provide information about BP readings from the patients to the APN
Finally the billing staff needs to provide information about the proper billing for in office versus in home BP
monitoring The practice change team will work once per week to coordinate the change process The
setting for the proposed practice change will be a medium size solo family practice office in a moderate size
city in the Midwest with a large or rapidly growing population of AAs
No participants from outside agencies will be involved in the implementation of this practice
change The monitoring of BP will be done by APNs The practice staff will monitor all interventions
Critical Appraisal of Evidence
Multiple sources of evidence have contributed to the development of the proposed evidence based
practice change These sources include one Cochrane meta-analyses review and eleven randomized
controlled trials The collection of evidence was obtained following an extensive literature review using the
following databases Cochrane CINAHL PubMed MEDLINE and PsycINFO The literature search was
derived from the following key words hypertension blood pressure usual care for hypertension tele-
monitoring telemedicine nurse practitioner advanced practice nurse and African Americans
Articles were selected for utilization based upon their applicability to the reduction of HTN in AAs Eighty
articles were reviewed however a majority was eliminated because they were greater than 12 years old
the sample size was too small they did not completely fit the aforementioned criteria for the proposed
practice change or they were lower levels of evidence The synthesis of evidence and strength of the
evidence tables are provided in Appendix B and C
Jaana Pare and Sicotte (2007) conducted a meta-analysis to investigate the efficacy of home
blood pressure monitoring via tele-monitoring towards the reduction of HTN Jaana Pare and Sicottes
(2007) findings indicated that the control of BP is better achieved when measured at home as opposed to in
clinical settings In addition to a reduction of HTN the utilization of home BP monitoring was also shown to
be beneficial in the identification of lsquoWhite coat syndromersquo Identification of lsquoWhite coat syndromersquo can
prevent over treatment of patients with anti-hypertensive medications Artinian Washington and Templin
(2001) performed a randomized control trial (RCT) to determine if the addition of tele-monitoring to the
usual care for BP management would reduce BP more than in those who just receive the usual care
Artinian (2001) concluded that patientsrsquo who received tele-monitoring in addition to the usual care
yielded the most significant reduction in BP over the course of the clinical trial In 2007 Artinian Flack
Nordstrom Hockman Washington Jen and Fathy built off the previously mentioned study performing a
RCT on AAs with HTN This study was comparing patients who received usual care to those patients who
received tele-monitoring in addition to usual care for BP management Artinian et al (2007) concluded that
those patients who received the usual care and tele-monitoring experienced a more significant decrease in
BP than the control group
Continuing to evaluate usual care McManus Mant Bray Holder Jones Greenfield Kaambwa
Bryan Little Williams and Hobbs (2010) performed a RCT on 527 hypertensive adults in England The
study was comparing the usual care provided by family physicians to patient self-management via tele-
monitoring The study concluded that over a monitoring period of one year those who received the self-
management intervention via tele-monitoring realized a greater reduction in BP when compared to those
with usual care Parati Omboni Albini Piantoni Giuliano Revera Illyes and Mancia (2009) performed a
RCT to compare patients who received usual care for HTN management to those patients who utilized
tele-monitoring for HTN management Parati et al (2009) concluded that those individuals in which tele-
monitoring were the main intervention experienced an overall greater reduction in HTN than those with
usual care
Brennan Spettell Villagra Ofili McMahill-Walraven Lowy Daniels Quarshie and Mayberry (2010)
performed a RCT on 954 hypertensive AA males This study compared the management of HTN by a
telephonic nurse and in home BP monitoring against those with just in home BP monitoring Brennan et al
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The
Strengthswas determined by ABP monitoring which provides BP values devoid of inconveniences such as the white-coat effect the advantage of combining self-measurement of BP at home with data teletransmission is supported by two additional findings
Weaknessesdesign prevented a comparison with the
defined by the occurrence of an office SBP of at least 140 mmHg or DBP of at least 90 mmHg and by an ambulatory mean daytime SBP of at least 130 mmHg or DBP of at least 80 mmHg (regardless of whether patients were or were not treated) Exclusion criteria were a diagnosis of secondary hyper- tension major systemic diseases atrial fibrillation or frequent cardiac arrhythmias or severe atrioventricular block that is conditions that could make HBPM and ABP measurements unreliable obesity (BMI gt30 kgm2) or an arm circumference of more than 32 cm or both to avoid inaccuracies in automated BP readings due to armndash cuff mismatch and any condition that might prevent patientsrsquo participation in the study for example technical problems due to incompatible phone lines at home

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
clinical settings In addition to a reduction of HTN the utilization of home BP monitoring was also shown to
be beneficial in the identification of lsquoWhite coat syndromersquo Identification of lsquoWhite coat syndromersquo can
prevent over treatment of patients with anti-hypertensive medications Artinian Washington and Templin
(2001) performed a randomized control trial (RCT) to determine if the addition of tele-monitoring to the
usual care for BP management would reduce BP more than in those who just receive the usual care
Artinian (2001) concluded that patientsrsquo who received tele-monitoring in addition to the usual care
yielded the most significant reduction in BP over the course of the clinical trial In 2007 Artinian Flack
Nordstrom Hockman Washington Jen and Fathy built off the previously mentioned study performing a
RCT on AAs with HTN This study was comparing patients who received usual care to those patients who
received tele-monitoring in addition to usual care for BP management Artinian et al (2007) concluded that
those patients who received the usual care and tele-monitoring experienced a more significant decrease in
BP than the control group
Continuing to evaluate usual care McManus Mant Bray Holder Jones Greenfield Kaambwa
Bryan Little Williams and Hobbs (2010) performed a RCT on 527 hypertensive adults in England The
study was comparing the usual care provided by family physicians to patient self-management via tele-
monitoring The study concluded that over a monitoring period of one year those who received the self-
management intervention via tele-monitoring realized a greater reduction in BP when compared to those
with usual care Parati Omboni Albini Piantoni Giuliano Revera Illyes and Mancia (2009) performed a
RCT to compare patients who received usual care for HTN management to those patients who utilized
tele-monitoring for HTN management Parati et al (2009) concluded that those individuals in which tele-
monitoring were the main intervention experienced an overall greater reduction in HTN than those with
usual care
Brennan Spettell Villagra Ofili McMahill-Walraven Lowy Daniels Quarshie and Mayberry (2010)
performed a RCT on 954 hypertensive AA males This study compared the management of HTN by a
telephonic nurse and in home BP monitoring against those with just in home BP monitoring Brennan et al
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
(2010) concluded that patients who received telephonic nurse intervention combined with in home BP
monitoring had a significant decrease in overall BP when compared to those that just had in home BP
monitoring Continuing to evaluate the effects of tele-monitoring in AAs McCant Mckoy Grubber Olsen
Oddone Powers and Bosworth (2009) performed a RCT to examine the feasibility of home tele-monitoring
among primary care patients with poor BP control Of the 588 participants 147 patients were randomized
to usual care The remaining 441 patients were randomized to receive either (1) a nurse-administered
tailored behavioral intervention (2) a nurse-administered medication management according to a
hypertension decision support system and (3) a combination of these two interventions McCant et al
(2009) concluded that 75 of patients were able to use tele-monitoring devices appropriately
Bosworth Powers Olsen McCant Grubber Smith Gentry Rose Houtven Wang Goldstein and
Oddone (2011) performed a RCT that examined the effects of a patient behavioral management
intervention medication management and a combination of the 2 interventions delivered by telephone and
activated by home BP monitoring among adults with HTN treated in primary care Bosworth et al (2009)
concluded that patients whose BP was poorly controlled at baseline exhibited a significant reduction in BP
with the combination of behavioral and medication management Hacihasanoğlu and Goumlzuumlm (2011)
echoed similar findings when they performed a RCT on 120 hypertensive patients who residence was in
Turkey The study concluded that targeted education from nurses resulted in a significant decrease in BP
when compared to those with usual care
Hill Han Dennison Kim Roary Blumenthal Bone Levine and Post (2003) performed a RCT on
309 hypertensive AA men This study compared the management of HTN by a team composed of a nurse
practitioner community health worker and physician with that of traditional care found in the community
After 36 months of evaluation Hill et al concluded that intervention delivered by the team of healthcare
providers was much more effective at lowering BP than the traditional care received Allen Dennison-
Himmelfarb Szanton Bone Hill Levine West Barlow Lewis-Boyer Donnelly-Strozzo Curtis and
Andersonrsquos (2011) RCT produced similar results The study concluded that interventions delivered by a
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Randomized Control Trial (RCT)
The study population included 309 hypertension AAs men between the ages of 21 and 54 years and residing in inner city Baltimore
The study evaluated the effectiveness of a more intensive comprehensive educational-behavioral-pharmacologic intervention by a nurse practitioner-community health worker-physician (NPCHWMD) team and a less intensive education and referral intervention in controlling blood

This randomized clinical trial compared the effect of a lessintensive intervention to a more intensive intervention to improve HTN in AAs
At 36 months the mean SBPDBP change from baseline was -75-101 mm Hg for less intensive group (p=001 and 005 for between-group differences in SBP and DBP respectively)

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The
Strengthswas determined by ABP monitoring which provides BP values devoid of inconveniences such as the white-coat effect the advantage of combining self-measurement of BP at home with data teletransmission is supported by two additional findings
Weaknessesdesign prevented a comparison with the
defined by the occurrence of an office SBP of at least 140 mmHg or DBP of at least 90 mmHg and by an ambulatory mean daytime SBP of at least 130 mmHg or DBP of at least 80 mmHg (regardless of whether patients were or were not treated) Exclusion criteria were a diagnosis of secondary hyper- tension major systemic diseases atrial fibrillation or frequent cardiac arrhythmias or severe atrioventricular block that is conditions that could make HBPM and ABP measurements unreliable obesity (BMI gt30 kgm2) or an arm circumference of more than 32 cm or both to avoid inaccuracies in automated BP readings due to armndash cuff mismatch and any condition that might prevent patientsrsquo participation in the study for example technical problems due to incompatible phone lines at home
physical examination and two BP measurements at a 5 min interval using the validated oscillometric device that had to be used for HBPM (Tensiophone device Tensiomed Budapest Hungary) The software of this device was validated according to the International Protocol recommended by the European Society of Hypertension Working Group on BP monitoring [11] The device is equipped with a built-in modem permanently plugged to the house phone line and subjected to remote programming of the frequency of measurements as well as of the time of a telereminding beep which can be sent to the
software version 115 (SPSS Inc Chicago Illinois USA) Quantitative variables were described through the calculation of average 1113088 SD values for each dataset Discrete variables were described by their absolute and relative frequency of occurrence Between-group differences were assessed by analysis of variance for continuous variables and by the chi-squared test of MantzelndashHaenszel for discrete variables The between-group comparison of the percentage of patients with normalized ABP was made by chi- squared test Throughout the study the level of statistical significance was set at a P value of less than 005

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
community health worker and nurse practitioner were more effective at recuing cardiovascular risk factors
than usual care
Of the 12 articles critiqued and later presented in the Evidence Rubric (see Appendix D) it
can be concluded that there is strong evidence to support the utilization of advanced practice nurses and
tele-monitoring to reduce HTN amongst African American men aged 40 years and older
Plan a Pilot Test for the Change
After review of several theoretical frameworks Rosswurm and Larrabeersquos framework was chosen
to guide the EBP proposal The framework involves six steps (1) assessing the need for change (2)
locating evidence (3) analyzing the evidence (4) designing a practice change (5) implementing the
practice change and (6) maintaining the change (Melnyk amp Fineout-Overholt 2011) This model was
selected because it is simple easy to understand and comprise steps that suitably fit this research project
The specific aim of the EBPCP is to implement a tailored culturally-sensitive educational
intervention incorporating BP management via tele-monitoring by APNs employed by the private practice
The educational intervention also includes diet management increasing physical activity weight control
medication adherence and assessment of lifestyle changes that will offer adequate control of HTN among
AA males aged 40 years and older
The setting for the proposed EBPCP will be an inner-city medium size solo family practice office in
a moderate size city in the Midwest The practice is run by one physician and two APNs The practice is
surrounded by small business complexes with convenience parking accessible to main roads and interstate
highways Nearby residential areas are within a quarter mile of the family practice office in all directions
The nearest healthcare facilities including a moderate hospital dentist office and moderate nursing home
are within two miles along the main road on either direction The practice site serves between 6000 and
8000 visits per year of 90 indigent AA patients ranging from minor seasonal flu complaints and allergies
to severe and life-threatening events from chronic disease complications requiring referrals to hospitals
management of acute and minor illnesses in adults aged18 years and older
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

Meta-analysis from Cochrane database
14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors
Comparing results of all the 14 studies
The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
The EBPCP has been endorsed by the owner of the practice (physician) and his associates
(APNs) because the EBPCP will augment current health care of this vulnerable population The only
resistance may come from nursing staff because the EBPCP may add more responsibilities to the routine
activities However after the introduction of the benefits of the EBPCP and addressing the questions and
concerns of nursing staff it is anticipated that the EBPCP will gain support because it will help nurses to
provide evidence based practice improvements in outcomes of AAs with HTN
PopulationSample
Last yearrsquos patient population at this practice was reported to be 7058 visits 89 (6300) were
AAs This estimates to about 117 AAs seen per week at this practice for health care services or about 19
AAs per day with the exception of Sunday when the practice is closed Of the 6300 visits half were AA
males ages 40 years and older Considering such a high percentage of AA patients seen in this practice on
a daily basis it will be reasonable to suggest that the EBPCP team should be able to recruit 60 AA males
with HTN into the EBPCP during the 6-months data collection period
Sampling plan
The purposed population for the EBPCP is AA males with medical diagnosis of HTN receiving
routine and follow-up care for management of HTN at the family practice office (eligibility criteria) Their
care at the practice creates the target population from which the sample will be drawn The sample will
include AA males ages 40 years and older who meet the following inclusion criteria (1) have a systolic
blood pressure reading gt 140 mmHg andor diastolic blood pressure reading gt 90 mmHg on two separate
occurrences and who are taking or not taking anti-hypertensive medications or (2) systolic blood pressure gt
130 mm Hg systolic andor diastolic blood pressure gt 80 mm Hg for potential candidate with diabetes or
chronic kidney disease and (3) able to read and speak English Exclusion criteria include (1) age less than
40 years (2) females (3) inability to read and speak English (4) non- AAs and (5) children Purposive
sampling will target all available AA males who will meet the above inclusion criteria The total number of
subjects in the study is 50 Over sampling will occur by 20 to account for attrition (N=60)
Recruitment procedures
A member of the EBPCP team will meet face to face at a convenient time with all six RNs who are
practicing at the family practice office and inform them of the proposed EBPCP They will be instructed to
invite potential candidates into the study and explain eligibility and exclusion criteria and address all of their
questions and concerns before proceeding with the proposed practice change Non- RNs will be informed
to post the EBPCP on the information board and to notify RNs of potential candidates The RN will be
instructed to initiate the study purpose and invite eligible patients into the study prior to or following the
initial health assessment by the physician or APNs taking into consideration the urgency of the purpose of
the visit and the present conditions of the candidate AA males ages 40 years and older who meet inclusion
criteria will be invited to participate in the EBPCP by APNs to improve outcomes associated with HTN in AA
males ages 40 years and older
The APN will obtain the patientrsquos written signature on the Informed Consent (IC) on WSU
letterhead from willing participants after explanation about benefits versus risks of EBPCP The participants
will also be informed that there will be no penalty or coercion for refusing to participate in the EBPCP The
APN will provide explanation regarding BP and weight assessment using anthropometric measures and
about the types of questions that the candidates will answer and how long it will take to complete the
questionnaire(s) In addition the APN will assess for questions or concerns from the participants The
original copy of the IC will be given to the patient and a copy will be kept in a locked files cabinet for a
member of the EBPCP to collect once a week
Patients will be given a $15 gift card to Walmartrsquos store for participation in the questionnaire
(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

(and or intervention) initially and a $20 bi-monthly for a total of the $75 at the end of the EBPCP
Recruitment into the EBPCP will continue until the desired number of participants has been recruited into
the EBPCP A member of EBPCP will have a contact number to be reached at all time for questions and
concerns by the APNs andor the practice administration
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The
Strengthswas determined by ABP monitoring which provides BP values devoid of inconveniences such as the white-coat effect the advantage of combining self-measurement of BP at home with data teletransmission is supported by two additional findings
Weaknessesdesign prevented a comparison with the
defined by the occurrence of an office SBP of at least 140 mmHg or DBP of at least 90 mmHg and by an ambulatory mean daytime SBP of at least 130 mmHg or DBP of at least 80 mmHg (regardless of whether patients were or were not treated) Exclusion criteria were a diagnosis of secondary hyper- tension major systemic diseases atrial fibrillation or frequent cardiac arrhythmias or severe atrioventricular block that is conditions that could make HBPM and ABP measurements unreliable obesity (BMI gt30 kgm2) or an arm circumference of more than 32 cm or both to avoid inaccuracies in automated BP readings due to armndash cuff mismatch and any condition that might prevent patientsrsquo participation in the study for example technical problems due to incompatible phone lines at home

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
The EBPCP will consist of a tailored culturally sensitive education intervention incorporating tele-
monitoring by APNs employed by the private practice The educational intervention will include diet
management physical activity weight control medication adherence and assessment of lifestyle changes
The intervention will be measured using various instruments including BP and weight via anthropometric
measures exercise pattern (Lorig et al 1996) diet type and frequency (ordinal scale) medication
adherence (Moriskyrsquos scale) and smoking and alcohol consumption (self-reported on a nominal scale) the
later scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1[kappa statistics] and
078-096[Spearman Rho correlation] Only the overall content validity and reliability of the questionnaire
was reported by the author in the literature Individual scale validity and reliability of the exercise scale and
medication adherence scale was not reported in the literature In addition we plan to use a questionnaire
developed by the team incorporating three open ended questions about the participantsrsquo satisfaction with
the educational intervention
Resistance might come from the staff because the EBPCP may incorporate new protocol and
development of new policies regarding the management or education of AA males with HTN The purposed
changes may create stress and provoke resistance to APNs because of additional work responsibilities in
managing patients With the help of the physician and APNs changes can be made incrementally and
adequate education about linkage of the benefits of the EBPCP resulting in better patientsrsquo outcomes
Implementation of the change may require special accommodations such as extra time for
collecting data and educating patients It is also paramount to consider additional time commitment for the
patients when participating in the proposed educational practice change Special accommodations and
flexibility to meet their needs is crucial to acknowledge their commitment to the EBPCP
The proposed practice change will occur incrementally during a six-month time period Please refer
to the Gantt chart for the proposed timeline (Appendix D) During the first month permission will be
obtained from the practice administration to conduct the EBPCP Stakeholders will get involved with the
introduction of PICOT question Identification of supporters and laggards will be determined Education
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account
may improve the quality of decision making and provide the ongoing surveillance required for timely interventions for poor BP control
48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses
for the correlation of patientsrsquo repeated measurements over time Mean differences between each intervention group and the usual care group at 612 and 18 months were calculated along with corresponding 95 CI using SAS ESTIMATE statements

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
about the benefits of EBPCP will be provided to the staff and their concerns will be addressed by a member
of the EBPCP The EBPCP will also be introduced to the APNs during a scheduled team meeting to seek
their support for this practice change and to determine if they have concerns about the feasibility of carrying
out this practice change An open-ended interview guide will be developed by the team to determine patient
satisfaction with the proposed educational intervention (See appendix for questions)
Assessment of the practice will be conducted to develop an appropriate strategy for the change The
budget will be determined and funds allocated (see Appendix E) Patients who have met the inclusion
criteria and who are interested in the educational intervention will be phased in to the EBPCP during the
second through fifth month During this time period the APNs will determine data from the patientrsquos chart to
be transferred to a spreadsheet corresponding to all variables to be measured in the patients for statistical
analyses A formative evaluation will be done to determine the progress of the EBPCP and adjustments will
be made depending on the results During the sixth month of the EBPCP summative evaluation will be
conducted and data will be analyzed to determine the results of the EBPCP
Successful strategies that will help persuade others to support arguments behind the EBPCP will
include providing opportunity to discuss others concerns addressing their questions and continuously
providing accurate information about the benefit of EBP Communicating with the FNPs periodically will be
helpful in determining any identified problems in implementing the EBPCP and if so the recommendations
they have to improve or halt any lack of success in carrying this out Providing education to all
stakeholders about EBP and following a SWOT analysis process by identifying strengths weaknesses
opportunities for success and delineating the threats or barriers with strategies to overcome them will be
beneficial in making this EBPCP a success This strategic plan will help to share the vision of the EBPCP
to overcome barriers to promote engagement of staff and key stakeholders and to establish incremental
goals for all people involved
Evaluation
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
The outcomes that will be measured in this EBPCP are blood pressure self-reported exercise
pattern weight self-reported diet frequency and portion control medication adherence self-reported
cigarette and alcohol use and patient satisfaction All of these outcomes will be measured at baseline and
again at one month three months and six months from the commencement of the educational intervention
The outcomes will be measured using various instruments including blood pressure and weight via
anthropometric measures exercise pattern (Lorig et al 1996) self-reported diet type and frequency
(ordinal scale) medication adherence (Moriskyrsquos scale) and smoking and alcohol consumption (nominal
scale) The latter scalersquos content validity was 086 and inter-rater reliability ranged from 089 to 1 [kappa
statistics] amp 078-096 [Spearman Rho correlation] Only the overall content validity and reliability of the
questionnaire was reported by the author in the literature Individual scale validity and reliability of the
exercise scale and medication adherence scale was not reported in the literature In addition we plan to
use the three-item open-ended interview guide developed by the team to ascertain the participantsrsquo
satisfaction with the educational intervention
The primary outcome of the study will be BP control measured at baseline one month three
months and six months using a standardized research protocol At each measurement point the APN will
ask the patients to rest for 5 minutes before obtaining 2 BP measurements using a digital
sphygmomanometer The participant will be weighed using a digital weighing scale During the same visit
participants will be asked to complete a structured 24-item questionnaire comprising four sections-
demographic profile lifestyle behavior (smoking drinking exercise and dietary habits) self-health
monitoring practices and medication adherence Demographic profile will include age gender educational
status marital status insurance and total household income Lifestyle behaviors- This section of the
questionnaire will include self-reported questions to determine cigarette and alcohol consumption on a
nominal scale Exercise scale modified from Lorig et al (1996) will be used to assess exercise pattern
Participants will be asked to indicate the type and frequency of physical activities on an ordinal scale
Dietary intake will be assessed by asking the type portion size and frequency of food on an ordinal scale
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

Meta-analysis from Cochrane database
14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
Self-health-monitoring practice- assessment will ascertain whether the participants had performed regular
self-health checking via tele-monitoring on BP and maintained records The measurement scale will be
dichotomous
Medication adherence will be assessed using Moriskyrsquos (1986) scale composed of 4 dichotomous
questions about medication use patterns The scale is quick and simple to use for subjects to indicate their
adherence to the physicianrsquos instructions A summative score will be calculated to reflect the level of
medication compliance A low score indicates high medication adherence
Data will be collected using the above mentioned questionnaire by the APNs in the out-patient solo
family practice Eligible patients will be invited to participate in the educational intervention Following the
invitation eligible patients will be asked to complete the questionnaires which can be completed in 25
minutes Privacy will be provided in a quiet area of the private practice office during the completion of the
questionnaire All questions will be answered by the APN The APN will also weigh the participant on a
digital weighing scale and record the weight
Donabedienrsquos (1982) program evaluation framework will guide this six-month educational
intervention The framework includes four elements structure process outcome and impact Structure
includes the social and physical resources in place to support the proposal EBPCP Process incorporates
what will occur during the EBPCP Outcomes include the early expectations after the practice change
whereas impact refers to the long term effects of the practice change measured against the ldquogold
standardsrdquo such as clinical practice standards developed by the American Heart Association in year 2012
For the purpose of this EBPCP we plan to incorporate the outcome during the six-month
educational intervention As a result of this practice change positive outcomes will be measured and
achieved by assessment of the following Decrease of blood pressure to within normal range lt12080
mmHg patients will report better lifestyle choices through selection of adherence to DASH increase in
physical activity weight control medication adherence and lifestyle changes (smoking cessation and
limited alcohol consumption) and an increase in patient satisfaction The Donabedienrsquos program evaluation
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

Meta-analysis from Cochrane database
14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
framework was chosen because it is simple and easy to understand and it includes the outcome element
among its evaluation strategy which is the main focus of this EBPCP
The practice change will be monitored by ascertaining changes in blood pressure self-reported
changes in adherence to DASH diet increase in physical activity weight control via anthropometric
measures medication adherence lifestyle changes (smoking cessation and limited alcohol consumption)
incrementally and over the six-month educational intervention Creating small successes along the way will
help in implementing the change For example during the six-month time period we will ask the patient
how they are managing behavioral lifestyles as measured by the stated measures
The long term effects of the practice change will be monitored by quarterly audits of charts to
evaluate the variables of interest When patients come back for regular follow up care BP readings within
normal range of 12080 mmHg will indicate that the practice change was successful in maintaining long-
term effects Patients who are unsuccessful in maintaining the practice change can be reeducated and
empowered Every six months the APNs will make phone calls to the patients and enquire regarding their
health status This will help nourish the new culture to make the change last
Success of the practice change project will be determined by the teamrsquos observation of changes in
the patientrsquos BP measurement and self-reported changes in adherence to the DASH diet increase in
physical activity weight loss smoking cessation decreased alcohol consumption and an increase in
patient satisfaction
This study will use non-parametric statistics (mean median mode range standard deviation
and frequency) to measure its variables and parametric statistics- analysis of variance (ANOVA) will be
used to measure four dependent variables including a decrease in SBP amp DBP adherence to DASH
increase in physical activity and a decrease in weight Data entry and interpretation will be done by WSU
Statistical Consultant Center in consultation with the researcher
Human Subjects
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

Meta-analysis from Cochrane database
14 studies investigating the use of home BP telemonitoring that were found in the scientific literature of which only three were randomized trials
The studies present evidence on the benefits of telemonitoring as a patient-management approach and their condition such as significant BP control better medication adherence changes in patientsrsquo lifestyle as well as their attitudes and behaviors

The findings of all the 14 studies were analyzed and compared
Home telemonitoring to support hypertension control by allowing fast interventions and adjustments in both treatment and medications improving patientsrsquo compliance and communication with their practitioners as well as reduce the lsquowhite coatrsquo effect(White coat effect-is defined as reproducible hypertension in the medical setting and normotension in the non-medical setting)
A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
Educational interventions will be screened by Expedited IRB at WSU However the Review Board
or Screening Committee at the family practice office will review the EBPCP and guarantee permission prior
to implementation of the proposed educational practice change with the goal of providing adequate
management of HTN among AA males aged 40 years and older The proposed practice change will consist
of an educational component as reported in the literature to improve health outcomes associated with HTN
among AA males aged 40 years and older by the APNs following instructions given by the EBPCP team
The data collected will be kept in the small locked file cabinet located in the practicersquos office only
accessible to the EBPCP team members and the APNs involved for statistical analyses Confidentiality and
anonymity will be kept as established by the practice and by the research protocol if any publication of
results will be done to disseminate information
Budget
Funding will be received from the American Heart Association National Clinical Research Program
This grant offers $77000 for two years to practitioners offering clinical studies that will promote
cardiovascular health This amount will be used for equipment and additional staffing to support the
increased level of blood pressure monitoring The APNs salary which is approximately $92000 per year will
be prorated for one dayweek which is approximately $9200 over a period of six months
The budget will be split in the following manner 50 will go to additional staffing and APNs salary
25 to purchasing equipment and updating the practice computer system to work with the tele-monitoring
system 15 to additional supplies needed to be able to take appropriate blood pressure measurements
and 10 for travel to patients homes for set up of the tele-monitoring system and patient education This is
shown as a pie chart in Appendix F
The cost of implementing this practice change will be higher in the first year due to the technology
updates that will be required This cost will decrease with time The cost will be justified if the intended
results of normal blood pressure for the patients of the practice and if the sequelae associated with high
blood pressure are reduced
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the
are otherwise not evident in clinical settings
home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
Conclusion
Overall the implementation of the EBPCP by APNs will be beneficial to the practice given the
strength of the evidence obtained from the various research studies on the benefits of tele-monitoring as
successful patient-management approach Improving the rate of blood pressure control for the AA male
population aged gt 40 years will help in preventing the sequelae associated with HTN and improve quality of
life Tele-monitoring may improve the quality of decision making and provide the ongoing surveillance
required for timely interventions for BP control although it may be more resource intensive than traditional
clinic visits

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

linked with patient feedback and medication titration may enhance access and improve outcomes for adults with hypertension
study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account
may improve the quality of decision making and provide the ongoing surveillance required for timely interventions for poor BP control
48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses
for the correlation of patientsrsquo repeated measurements over time Mean differences between each intervention group and the usual care group at 612 and 18 months were calculated along with corresponding 95 CI using SAS ESTIMATE statements
(95 CI -155 to -05 mmHg) at 18 months relative to usual care

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

TrainedOPD-GCRC personnel blinded to group assignment obtained three BP measurements at 1-min intervals with aHawksley random zero sphygmomanometerA trained
The only confidence interval (CI) reported was in the change in creatinine serum The relative hazard ratio associated with assignment to more intensive versus less intensive was 063 (hazard ratio 95 CI=036-111
This randomized clinical trial compared the effect of a lessintensive intervention to a more intensive intervention to improve HTN in AAs
At 36 months the mean SBPDBP change from baseline was -75-101 mm Hg for less intensive group (p=001 and 005 for between-group differences in SBP and DBP respectively)

A meta-analysis on the monitoring of BP indicates that the control of BP is better achieved when measured at home as opposed to in clinical settings especially in cases of low medication compliance co morbidities and uncontrolled hypertension The electronic transmission of data from home BP monitoring allowed regular communication with healthcare providers and supports reliable readings that
StrengthsTelemonitoring of patients with HTN appears to be an effective patient-management approach that supports BP control assists in identifying patients with the white coat effect and as such reduces the risk of over-treatment HTN telemonitoring supports patientsrsquo empowerment and reassurance by giving them direct responsibility for continuous monitoring of the BP and by ensuring regular communication with health care providers and immediate feedback even outside office hours and in remote areasWeaknessesissue of reimbursement for the

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The
Strengthswas determined by ABP monitoring which provides BP values devoid of inconveniences such as the white-coat effect the advantage of combining self-measurement of BP at home with data teletransmission is supported by two additional findings

home monitoring devices and services that are provided remains critical when introducing and advocating telemonitoring as a patient-management approachThe problem of decrease in compliance represents an important aspect that needs further explorationIt is critical to understand that home telemonitoring does not necessarily work equally among all patientsLimitationsthis review the heterogeneity of the studies found in the literature makes the comparison and aggregation of findings difficult Over all most of the studies were conducted over a short period of time and involved small samples of patients which limits the generalizability of the findings especially in relation to the sustainability and effectiveness of home telemonitoring as a patient-monitoring approach

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Randomized control trial (RCT)
A total of 588 veterans with a diagnosis of hypertension from the Durham VA Medical Center147 patients were randomized into the usual care arm 441 were randomized to receive one of three interventions that included home BP telemonitoringThe intervention arms were (1) a nurse-administered tailored behavioral intervention (2) a nurse-administered medication management according to a hypertension decision support system (3) a combination of 1amp2 (4) usual care
The feasibility of using home blood telemonitoring among primary care patients with poor BP control
A research assistant trained patients in the use of the telemonitoring equipment and gave instructions to take three BP readings a week on different daysThe BP monitor (AampD 767PC CareMatrix Inc) was used to transmit data via a wireless link to a home telephone line
The data were divided according to the number of alerts 0-2 vs gt 2 The percentage of intervention subjects with 0-2 vs gt2 technical alerts for baseline demographic characteristics was calculated Means and SDs were calculated for continuous variables of interest Differences in baseline characteristics between intervention subjects were calculated using a two-tailed chi-square test for categorical variables and t-tests for continuous variables Race and employment status were divided into 2 level variables (Caucasian vs non-Caucasian retired vs not retired) for the chi-square tests
The researchers expected that patients would be able to use BP telemonitoring devices successfully and thereby improve BP control decrease medication use and overall cost in comparison to using clinic measurements
During the first six months of experience in using the BP monitoring equipment 693 technical alerts were generated by 267 patients About half of these patients (112) generated more than two technical alerts Resolution of the alerts showed that 61 were caused by patient non-adherence Patient who generated gt2 technical alerts were younger (61 vs 64 years p=0001) and were more likely to be non-Caucasian (64 vs 47 p=0002) than those generating 2 or fewer alerts
Strengthswas successful in getting 75 of the patients to use the devices correctlyWeaknessespatients will require more support to use the equipment successfully For some patients this technology may not be appropriate or is problematic patients may be either non-adherent or unable to fulfill the intervention protocol The study team should be prepared for changes in the telephone system and device infrastructure and have alternative data collection methods available The increased time and attention required by the non-adherent patients or those unable to manage the technology may have significant cost implicationsLimitationsparticipants came from a pool of veterans who received their primary health care through the Durham VA primary care clinics

mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

cardiovascular disease prevention but is difficult to achieve and until recently has been the sole preserve of health professionals This study assessed whether self-management by people with poorly controlled hypertension resulted in better blood pressure control compared with usual care
invited to two training sessions run by the research team Participants were trained to monitor their own blood pressure for the first week of each month with a validated automated sphygmomanometer (Omron 705IT Omron Healthcare Europe Hoofddorp Netherlands) and to transmit blood pressure readings to the research team by means of an automated modem device (i-modem Netmedical De Meern Netherlands) which was connected to the sphygmomanometer and plugged into a normal telephone socket like an answerphone17 Two self-measurements were made each morning with a 5-min interval and the second
intervention group ranked self-monitoring as their preferred method of blood pressure monitoring compared with 103 (43) of 242 in the control group (plt0middot0001) Confidence Interval was set at 95

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The
Strengthswas determined by ABP monitoring which provides BP values devoid of inconveniences such as the white-coat effect the advantage of combining self-measurement of BP at home with data teletransmission is supported by two additional findings
Weaknessesdesign prevented a comparison with the
defined by the occurrence of an office SBP of at least 140 mmHg or DBP of at least 90 mmHg and by an ambulatory mean daytime SBP of at least 130 mmHg or DBP of at least 80 mmHg (regardless of whether patients were or were not treated) Exclusion criteria were a diagnosis of secondary hyper- tension major systemic diseases atrial fibrillation or frequent cardiac arrhythmias or severe atrioventricular block that is conditions that could make HBPM and ABP measurements unreliable obesity (BMI gt30 kgm2) or an arm circumference of more than 32 cm or both to avoid inaccuracies in automated BP readings due to armndash cuff mismatch and any condition that might prevent patientsrsquo participation in the study for example technical problems due to incompatible phone lines at home

study was BP control measured at baseline and at 6 12 and 18 months using a standardized research protocol At each measurement point a research assistant masked to intervention arms asked patients to rest for 5 minutes before obtaining 2 BP measurements using a digital sphygmomanometer
mixed-effects regression model was used to estimate differences in BP control at each post baseline time point for each of the intervention groups relative to usual care Marginalized estimates and corresponding confidence intervals for the proportion in BP control for the usual care and each intervention group at 6 12 and 18 months were calculated to estimate the relative improvement in proportion of patients with BP control For secondary analyses the intervention group effects on mean systolic and diastolic BPs over time were examined Longitudinal data analysis models with an unstructured covariance was utilized to account
may improve the quality of decision making and provide the ongoing surveillance required for timely interventions for poor BP control
48 were AA 92 were male and 59 of participants had their BP under control at baseline using standardized measurements Both the behavioral management and medication management alone showed significant improvement at 12 months-128 (95 CI 16-241) and 125 (95 CI 13-236) respectively-but not at 18 months In subgroups analyses among those with poor baseline BP control systolic BP decreased in the combined intervention group by 148mmHg (95 CI -218 to-78mmHg) at 12 months and 80 mmHg
poor baseline BP control the combined intervention significantly decreased systolic BP and diastolic BP at 12 and 18 monthsWeaknessesof the interventions alone was approximately $ 1100 per patient over 18 months Each intervention demonstrated improvements in BP control or systolic BP at 12 months none of these improvements were sustained at 18 months and did not result in lower medical care costsLimitationsthat the study participantrsquos blood pressures were lower than anticipated at baseline may have hampered the ability to detect larger improvements in the BP control in the overall analyses
for the correlation of patientsrsquo repeated measurements over time Mean differences between each intervention group and the usual care group at 612 and 18 months were calculated along with corresponding 95 CI using SAS ESTIMATE statements

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

Randomized Control Trial (RCT)
Subject were recruited from a family community center on the east side of Detroit The sample contained 26African Americans with a mean age of 59 years
This pilot study compared 2 experimental interventions- home TM plus usual care or community ndash based monitoring plus usual care-with usual care only
Participants had their BP measured and completed an investigator-developed demographic profile and HTN history formBPs were measured by using an electronic BP monitor (model A ampD UA 767PC) that has been validated and is accurate to within plusmn3 mm Hg or 5 and falls within the Advancement of Medical Instrument standards
Both experimental groups yield positive results with SBP and DBP dropped significantly during the 3-months intervention period (p=03p=04 respectively) In home TM group the decrease in SBPDBP was 1488+- 138mm Hg902+- 579 mm Hg at baseline to the 3-monthsrsquo follow up level of 1241+-1382mm Hg7558+- 114In the community-based monitoring group SBP dropped from baseline level of 15525+-
The purpose of this pilot study was to test the following hypothesis Persons who participate in nurse-managed home TM plus usual care or who participate in nurse-managed community-based monitoring (CBM) plus usual care will have greater improvement in blood pressure from baseline to 3 months follow-up than will persons who receive usual care only
Both the HT group and the CBM group had clinically and statistically significant (P lt05) drops in systolic blood pressure (SBP) and diastolic blood pressure (DBP) at 3 months follow-up with participants in the HT group demonstrating the greatest improvement (HT baseline SBP 1488 +- 138 DBP 902 +- 579 3 months follow-up SBP 1241 +- 1382 DBP
Strengthsdetermined that the cost of TM is about $150 per day which includes the cost of all equipment shipping the monitor directly to the personrsquos home telephone training and unlimited toll-free tele-transmission of the data If BP control can be achieved in a person with HTN and diabetes the incidence of extremely costly sequelae such as end-stage renal disease and heart failure can be reduced It is likely that the reduction in end-organ damage will far outweigh the cost of TM but testing of this assumption is required In addition
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

coupledwith a DM program that employs nurses who receivedcultural competence training as well as culturally sensitivematerials can improve BP compliance and reduce systolic BP more than a home BP monitoring device alone While a 31-point decrease in systolic BP may seem small the ALLHATstudy estimated that a 3-point change in systolic BP could explain a 10ndash20 difference in the risk of major cardiovascular events While mean systolic and diastolic BPs were lower for bothgroups

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The
Strengthswas determined by ABP monitoring which provides BP values devoid of inconveniences such as the white-coat effect the advantage of combining self-measurement of BP at home with data teletransmission is supported by two additional findings
Weaknessesdesign prevented a comparison with the
defined by the occurrence of an office SBP of at least 140 mmHg or DBP of at least 90 mmHg and by an ambulatory mean daytime SBP of at least 130 mmHg or DBP of at least 80 mmHg (regardless of whether patients were or were not treated) Exclusion criteria were a diagnosis of secondary hyper- tension major systemic diseases atrial fibrillation or frequent cardiac arrhythmias or severe atrioventricular block that is conditions that could make HBPM and ABP measurements unreliable obesity (BMI gt30 kgm2) or an arm circumference of more than 32 cm or both to avoid inaccuracies in automated BP readings due to armndash cuff mismatch and any condition that might prevent patientsrsquo participation in the study for example technical problems due to incompatible phone lines at home
physical examination and two BP measurements at a 5 min interval using the validated oscillometric device that had to be used for HBPM (Tensiophone device Tensiomed Budapest Hungary) The software of this device was validated according to the International Protocol recommended by the European Society of Hypertension Working Group on BP monitoring [11] The device is equipped with a built-in modem permanently plugged to the house phone line and subjected to remote programming of the frequency of measurements as well as of the time of a telereminding beep which can be sent to the
software version 115 (SPSS Inc Chicago Illinois USA) Quantitative variables were described through the calculation of average 1113088 SD values for each dataset Discrete variables were described by their absolute and relative frequency of occurrence Between-group differences were assessed by analysis of variance for continuous variables and by the chi-squared test of MantzelndashHaenszel for discrete variables The between-group comparison of the percentage of patients with normalized ABP was made by chi- squared test Throughout the study the level of statistical significance was set at a P value of less than 005

Interview Sample Questions for Patientsrsquo Satisfaction Evaluation
Open-ended questions
1) How is this educational intervention via tele-monitoring helpful to you in managing your HTN
adhering to the BP medications BP monitoring increasing physical activity diet control smoking
cessation and decreasing alcohol consumption
2) How satisfied are you with the proposed educational intervention incorporating home tele-
monitoring by APNs
3) What additional information would you want us to include in this educational intervention
17014mm Hg to 1423+-121 and DBP dropped from 8942+-1095 to 7825+-686 In the usual care group BPs were unchanged withLarge effect sizes were found (f=059 and 053) for SBP and DBP respectivelyDespite the small sample size the results indicated that participants in the home TM and community-based monitoring groups had clinically and statistically significant reductions in both SBP and DBP during the 3 month monitoring period compared to the participants in the usual care group
7558 +- 114 CBM baseline SBP 15525 +- 17014 DBP 8942 +- 1095 3 months follow-up SBP 1423 +- 121 DBP 7825 +- 686) There was little change in SBP or DBP at 3 months follow-up in the usual care only group CONCLUSION These are important pilot results which if replicated in a larger sample will significantly improve care for urban African Americans with hypertension
TM has the ability to identify patients with white-coat HTN thereby avoiding excess treatmentWeaknesseswe know that there may be advantages to home BP TM there is a need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention It is important to determine how much the intervention helped participants make BP monitoring and lifestyle modification a routine part of their daily livesLimitationscommunity- based approaches to monitoring BP hold promise as a means of facilitating access to care and obtaining control of HTN More research is needed

invited to two training sessions run by the research team Participants were trained to monitor their own blood pressure for the first week of each month with a validated automated sphygmomanometer (Omron 705IT Omron Healthcare Europe Hoofddorp Netherlands) and to transmit blood pressure readings to the research team by means of an automated modem device (i-modem Netmedical De Meern Netherlands) which was connected to the sphygmomanometer and plugged into a normal telephone socket like an answerphone17 Two self-measurements were made each morning with a 5-min interval and the second

Self home blood pressure monitoring (HBPM) has a number of potential advantages in the management of hypertension [1] These advantages include avoidance of the lsquowhite-coat effectrsquo availability of multiple BP readings over a wide time window
Baseline office blood pressures were 149 W 12 89W9 and 148W1389W7mmHg in groups A (nU111) and B (n U 187) respectively the corresponding daytime values being 140 W 1184 W 8 and 139 W 1184 W 8 mmHg The

receiving treatment for hypertension with two or fewer antihypertensive drugs had a blood pressure at baseline of more than 14090 mm Hg and were willing to monitor their own blood pressure and self-titrate medication The age range for eligibility had been increased from 35ndash75 years to 35ndash85 years after 3 months when it became apparent that older patients were able to undertake the trial procedures and there were concerns about recruitment Exclusion criteria were blood pressure more than 200100 mm Hg postural hypotension (gt20 mm Hg systolic drop) terminal disease dementia score of more than ten on the short orientation memory concentration test14 hypertension not managed by their family doctor or spouse already randomized to study group This randomized controlled trial was undertaken in 24 general practices in the UK
cardiovascular disease prevention but is difficult to achieve and until recently has been the sole preserve of health professionals This study assessed whether self-management by people with poorly controlled hypertension resulted in better blood pressure control compared with usual care
invited to two training sessions run by the research team Participants were trained to monitor their own blood pressure for the first week of each month with a validated automated sphygmomanometer (Omron 705IT Omron Healthcare Europe Hoofddorp Netherlands) and to transmit blood pressure readings to the research team by means of an automated modem device (i-modem Netmedical De Meern Netherlands) which was connected to the sphygmomanometer and plugged into a normal telephone socket like an answerphone17 Two self-measurements were made each morning with a 5-min interval and the second
intervention group ranked self-monitoring as their preferred method of blood pressure monitoring compared with 103 (43) of 242 in the control group (plt0middot0001) Confidence Interval was set at 95
telemonitoring of blood pressure measurements represents an important new addition to control of hypertension in primary care
assigned to self-management (n=263) or control (n=264) of whom 480 (91 self-management n=234 control n=246) were included in the primary analysis Mean systolic blood pressure decreased by 12middot9 mm Hg (95 CI 10middot4ndash15middot5) from baseline to 6 months in the self-management group and by 9middot2 mm Hg (6middot7ndash11middot8) in the control group (difference between groups 3middot7 mm Hg 0middot8ndash6middot6 p=0middot013) From baseline to 12 months systolic blood pressure decreased by 17middot6 mm Hg (14middot9ndash20middot3) in the self-management
compliance rateWeaknessesa need for more research because we do not know the effects of this strategy on long-term control of BP The next phase of research needs to monitor the effects of the intervention for a longer period and allow for a gradual reduction in the intensity of the intervention
reading acted upon A color traffic light system was used by participants to code these readings as green (below target but above safety limit) amber (above target but below safety limits) and red (outside of safety limits) A month was deemed to be ldquoabove targetrdquo if the readings on 4 or more days were above target
group and by 12middot2 mm Hg (9middot5ndash14middot9) in the control group (difference between groups 5middot4 mm Hg 2middot4ndash8middot5 p=0middot0004) Frequency of most side-effects did not differ between groups apart from leg swelling (self-management 74 patients [32] control 55 patients [22] p=0middot022)
