Abstract Background Poor adherence to medication can
lead to suboptimal outcomes, and is reported to occur
frequently. Pharmacists in some countries are funded to
support the appropriate use of medications in patients and
enhance medication adherence, by providing services such
as Medicines Use Review (MUR). Objective To describe
and investigate factors that may influence patients’
knowledge and perceptions of and adherence to medica-
tions as determined during MUR. Setting Community
pharmacies in a locality in New Zealand. Method Fol-
lowing consent from five MUR service providers, records
of patients’ MUR consultations conducted between
November 2007 and December 2011 were retrospectively
reviewed for information on patients, services, and out-
comes. Using multilevel mixed-effects logistic regression,
factors that predicted the providers’ score of the patients’
medication knowledge, and the patients’ score of their
adherence to and perceptions of medications, were inves-
tigated. Main outcome measure patients’ knowledge, per-
ceptions and adherence scores. Results A total of 353 MUR
patients’ records were evaluated. The median (IQR) age of
patients was 73 (63–81) years. About 41.1 % of patients
were Maori. A total of 204 (57.8 %) patients had two MUR
consultations and only 53 (15 %) had four. The mean score
of patients’ knowledge, perceptions of, and adherence to
medications were found to increase in each visit which
suggests that adherence support by pharmacists might
improve patients’ outcomes. Females had higher medica-
tion knowledge scores than males (OR 3.09, 95 % CI
1.29–7.44). There was some evidence to suggest Maori had
lower scores for knowledge of medications than non-Maori
(OR 0.092, 95 % CI 0.02–0.36). In addition, longer dura-
tion in the program predicted better scores for medication
knowledge, adherence and perceptions of medications.
Conclusions MUR was found to have the potential to
improve the scores of patients’ knowledge and perceptions
of and adherence to medicines, and factors such as gender,
ethnicity and longer duration in the services were found to
predict these outcomes.
Keywords Community pharmacy services � Medication
adherence � Medication knowledge � Medication review �New Zealand � Pharmaceutical care services � Pharmacists
Impact of findings on practice
• When providing the MUR adherence based services,
pharmacists should consider factors that may influence
patients’ outcomes such as gender, ethnicity and longer
engagement with the service.
• Where possible, the influence of gender, ethnicity and
longer engagement with the MUR service should be
discussed with patients, using specific counselling and
educational strategies.

Introduction
The prevalence of poor adherence to medications is high. It
is estimated that within developed countries, around 50 %
of patients with chronic diseases have poor adherence to
their medication treatment plan [1, 2]. Poor adherence to
medications can lead to negative outcomes on patients’
health such as suboptimal clinical benefit, hospitalisation
and death [3, 4]. It also carries a large economic burden to
healthcare systems [3]. In a number of countries pharma-
cists conduct medication reviews to decrease drug related
problems (DRPs) and to improve adherence to medications
[5, 6]. One example of this type of funded medication
review service to improve and support adherence to med-
ication is MUR [5, 6].
Medicines Use Review services in New Zealand are
defined as a structured and systematic review of all
patients’ current therapy [7]. MUR aims to improve the
patient’s understanding of their medication-related health
outcomes by identifying access, adherence, and day-to-day
management issues and setting goals with the patient to
resolve these issues [7]. The service involves patients
spending time with the pharmacist to discuss the best way
to manage and get the most out of their medication. It
comprises educational activities, counselling on current
medications and medical conditions to improve adherence,
removal of out of date medications, aligning dispensing of
medication, and reporting of medication adverse effects
[7]. Similar to the MUR service in the United Kingdom
(UK), MUR services in New Zealand usually take place
without pharmacists having access to clinical information.
MUR is founded on techniques to improve medication
administration techniques and adherence and it does not
include assessment of the appropriateness of medication
therapy [7, 8]. Patients can engage the services by self-
referral or referral from prescribers, pharmacists, primary
health care nurses or nurse practitioners [7]. In New Zea-
land, MURs can be conducted either at the pharmacy, at the
patient’s home or by telephone. MUR pharmacists are
funded based on a ‘‘fee-for-service’’ model by their District
Health Board (DHB) for up to four MURs per patient per
year. The fees vary between localities but they are usually
paid between $100 and $150 for three MUR consultations,
to $181–$200 for four MUR consultations per patient per
year [9]. In fee-for-service MUR, the services are carried
out by pharmacists in their usual settings where they may
have more limitations or barriers in implementing the
services to patients e.g. be subject to time, staffing and
resource constraints. This differs from a service being
provided in a highly research controlled environment. In
New Zealand, GPs are not reimbursed for being involved in
medication review services, as occurs in Home Medication
Review services in Australia.
Funding for this service in New Zealand commenced in
2007 [6]. During the first year of the service, MUR was
reported to have a low-uptake [9]. Of 20 DHBs, only five
(25 %) were funding their community pharmacists to
provide the service [9]. The service has steadily increased
in the past few years, with 11 DHBs in 2011 reported to be
funding their community pharmacists for MUR services
[10]. Common barriers to the uptake of MUR include; no
current contract with funders, a complex claim process,
insufficient time, and general practitioners and patients
lacking interest in the service [9].
While these services are available internationally there
are a limited number of papers relating to the outcomes of
the services, most have focused on patient perspectives. A
recent qualitative paper by Latif et al. [11] reported that
patients were found to be satisfied with the service despite
the majority believing that their knowledge about medi-
cations was not improved by the service. To our knowledge
no study, however, has evaluated the outcomes of MUR
services quantitatively in relation to its aims of improving
patients’ knowledge, perceptions of, and adherence to
medications. In addition, no study has investigated factors
that may influence patient outcomes in a fee-for-service
MUR.
Aim of the study
This study aims to: (1) describe the fee-for-service MUR
characteristics provided in a locality in New Zealand (2)
quantify the MUR service outcomes on patient’s knowl-
edge and perceptions of, and adherence to their medica-
tions and (3) investigate factors that may influence those
outcomes.
Ethical approval
Ethical approval for this study was granted by the New
Zealand Northern Regional Ethics Committee, reference
number NTX/11/EXP/182.
Method
The study was conducted retrospectively through exami-
nation of MUR patients’ consultation records documented
by pharmacists in one locality in New Zealand. The current
study design was chosen to capture the effect of fee-for-
service (funded service) MUR by community pharmacists.
Although randomised controlled trials (RCTs) are gener-
ally considered the best design for this type of study, they
are often difficult to carry out when the service that is being

explored is part of current practice. In addition, the highly
structured setting of an RCT does not necessarily reflect
current practice. The locality was selected because a MUR
service had been in place since 2007. At the time of the
study, there were seven MUR providers in this locality.
Providers’ were located in two geographical areas. Six
providers were in the city area with a population of
approximately 80,000 and one in a rural area with a pop-
ulation of almost 9,000 [12]. All MUR providers were
invited to participate in the study and an invitation letter
and information sheet about the study was mailed to them.
Participation in the study was voluntary and providers who
agreed to participate were asked to return their consent
form to the researcher, EH. Providers were not involved in
collection, collation or analysis of the data.
Data collection was performed by EH at the providers’
workplace (pharmacy or office). All MUR consultation
records for each visit (e.g. visit 1 up to visit 4) were scanned
and relevant data were extracted from the forms. Inclusion
criteria were those records that had complete documenta-
tion and were within the dates of initially receiving funding
until December 2011. Data extracted consisted of patients’
age, gender, ethnicity and health issues (as documented by
the pharmacist with data usually gained from patients’
interviews), reasons for MUR, number of visits, information
about the medication used and DRPs identified (defined as a
circumstance related to a patient’s use of a drug that actu-
ally or potentially prevents the patient from gaining the
intended benefit of the drug). Since the results on the types
of DRPs found during MUR were worthy of a detailed
investigation and discussion, the authors have reported the
findings in a separate paper [13]. The providers’ score of the
patients’ knowledge, adherence behaviour and perceptions
of medications were also collected. The score, that rated by
pharmacists based on patients’ response, was allocated on a
scale of 1–4, and are presented in Table 1. Each item was
scored separately with the lowest score reflecting the
poorest performance (for example a ‘1’ for knowledge
represented no knowledge about medications). This scoring
system was developed by the service’s funders and was
implemented by the MUR providers. The use and imple-
mentation was not influenced by this study.
Data were analysed descriptively with Microsoft Excel
and inferentially using IBM SPSS statistics version 20 and
Stata, version 12 [14]. Multilevel models were used to
allow for correlated observations within pharmacy (indi-
viduals) and individual (multiple observations over time).
Within that framework, logistic regressions were used to
model a binary outcome for each of knowledge, perception
and adherence to medications. The score of 1 and 2 were
categorised as ‘poor achievement’ (e.g. poor knowledge,
poor adherence and poor perceptions about medications)
and score of 3 and 4 were categorised as ‘good
achievement’ (e.g. good knowledge, more adherent, and
more positive about medications).
The fixed effects included in the models were age,
gender, and ethnicity, number of medications e.g. short
term and long term medications and duration in the pro-
gram (up to 6 months and more than 6 months). Prior to
the construction of the models, univariate tests were used
to determine which variables might be important in the
modelling of each measure: age, gender, ethnicity, number
of reason for MUR, number of long and short-term medi-
cations use, number of co-morbidities, total number of
medications and duration in the service. Only variable with
p values \0.25 will be included in the multivariate model
(results of univariate analysis available in ‘‘Appendix 1’’).
Following the common practice in health research, vari-
ables such as age and gender were always included. In the
multivariate model, a p value of \0.05 was considered
statistically significant.
Results
Of the seven MUR providers, five agreed to participate in
the study. Four providers were community pharmacists and
one provided a local domiciliary pharmacist support ser-
vice. Four providers were in the city area and one provider
was located in a rural area, 146 km from the city.
A total of 353 MUR patients’ consultation records were
reviewed. Patients’ characteristics according to the service
providers are presented in Table 2. The median age (IQR) of
patients was 73 (63-81) years. There were 199 (56.4 %)
female participants in this study. A total of 131 of the par-
ticipants were Maori (n = 131, 41.1 %). The median num-
ber of comorbidities was two (range between 1 and 11) and
patients used a median of eight medications (range 2–19).

Between November 2007 and December 2012, a total of
709 MURs were conducted. All patients (n = 353) in this
study attended visit one, half of the patients (n = 204,
57.8 %) returned for visit two, 99 (28 %) continued to visit
three and 47 (13.3 %) patients had four visits. Reasons for
not returning for MUR or no rescheduled visit were not
recorded. Regardless of the number of visits, a total of 254
patients attended the service up to 6 months and 99 were
followed-up for more than 6 months (range from 6 to
41 months).
In visit one, the majority of MUR services were con-
ducted at the patients’ home (n = 185, 52.4 %) or at the
pharmacy (n = 126, 35.7 %). Others were conducted at the
GPs’ surgery (n = 21, 5.9 %) or in other settings (n = 5,
1.4 %) such as the patients’ workplace or a relatives’
home. The setting was not recorded for 16 patients (4.5 %).
During visit two, three and four, most follow-ups were
conducted at the pharmacy (n = 139, 39 %) or by tele-
phone (n = 122, 34.3 %).
The most common reasons for MUR, besides having at
least one chronic disease, were taking five or more medi-
cations (n = 319, 90.4 %), having DRPs (n = 147,
41.6 %), taking medication with high risk for adverse
effects (n = 127, 35.9 %) and having a recent hospital
admission (32.0 %). Although enrolment in the service did
not require referral, 53 patients (15 %) were referred to
pharmacists for the services. Of these, 37 were referred by
GPs. Other referrals were from nurses (n = 3), other
pharmacists (n = 5), or independent organisations such as
a Hospice or the Salvation Army (n = 8).
The mean scores for patients’ knowledge, perceptions of,
and adherence to medication for each visit (rated by phar-
macists based on patients’ response) is presented in Table 3.
When knowledge, adherence and perception scores of
patients who continued the services were compared to
patients who did not have a further visit (using Mann–
Whitney U test), no significant differences were found
except during the third visit where more patients with lower
adherence score did not return to the program, p \ 0.001
(see ‘‘Appendix 2’’). Table 4 provides the odds ratio (OR)
of potentials factors of being a good achievement (score 3 or
4) in medication knowledge, perceptions and adherence.
Based on a multivariate analysis, the findings indicated that
women were three times more likely to attain a good
achievement in knowledge of medication compared with
men (OR 3.09, 95 % CI 1.29–7.44). In addition, patients
with Maori ethnicity appeared to be less likely than non-
Maori to attain good achievement in knowledge of medi-
cation score (OR 0.092, 95 % CI 0.023–0.362). Patients
who engaged with the services longer were more likely to

attain good achievement in knowledge of medication score.
The odds of patients attaining good achievement in medi-
cation knowledge if engaged up to 6 months, are about six
times those at the start of the program (OR 6.28, 95 % CI
2.59–15.2), while it is about 20 times the odds at more than
six months (OR 20.1, 95 % CI 5.49–73.5) (see Table 4). A
good achievement in knowledge of medication was also
found to be predicted by the number of short term medi-
cations such as antibiotics or anti-diarrhoeal medicines
(OR1.33, 95 % CI 1.03–1.72).
Only length of follow-up period was predictive of
patients’ good achievement in medication adherence and
perceptions about medications (score C3) (see Table 4).
Patients who were in the program longer were more likely
to attain a good achievement in adherence score: followed-
up up to 6 months (OR 15.3, 95 % CI 5.30–44), followed-
up for more than 6 months (OR 13.4, 95 % CI 4.0–44.9).
The similar pattern was also seen with good achievement in
perceptions score: followed-up up to 6 months (OR 14.1,
95 % CI 4.42–44.8), followed-up more than 6 months (OR
33.2, 95 % CI 5.72–193). Age categories (1–39, 40–64,
65–74 and [75), gender, number of medications, number
of co-morbidities were not found to predict the scores
(p [ 0.05) (see Table 4).
Discussion
The current study provides insight into the characteristics of
fee-for-service MUR and its outcomes within the New
Zealand context. Commonly, MUR services in this study
were provided by pharmacists as face to face consultations
with patients either at the pharmacies or at patients’ homes.
The most common criteria for enrolment in MUR in this
locality were taking five or more medications, or having
DRPs. As expected (due to the criteria), the majority of
patients enrolled in MUR services were 65 years and over
(n = 247, 70 %). The current criteria for MUR in New
Zealand include patients with multiple medications and with
DRPs. Older people are more likely to meet these criteria
because they tend to consume many medications due to
chronic disease [15]. Furthermore, with age-related physio-
logical changes, older people are at increased risk of DRPs or
adverse drug events, and the consequent risk of hospitaliza-
tion [15]. Older people have been reported to commonly have
problems with day-to-day medication use such as difficulties
in remembering to take their medications, problems in
swallowing tablets/capsules or reading the labels or opening
the medication packets or bottles [16]. Since a systematic
review by Guaraldo et al., found that the prevalence of
inappropriate medication use in community-dwelling older
people is high (ranging from 11.5 to 62.5 %) [17], a MUR
service that does not include an assessment of the appropri-
ateness of medication therapy may not be the safest option for
patients. Instead, as suggested in our earlier publication,
funding a clinical medication review alongside a MUR may
be necessary to ensure patient safety [13]. The wide variation
of prevalence of inappropriate use of medication reported by
Guaraldo et al. [17] was thought to be caused by the diversity
of criteria defining inappropriate medication use.
From the results (see Table 3) the mean score of patients’
knowledge, perceptions of, and adherence to medications
was found to improve following MUR visits. This shows that
MUR could potentially improve patients’ outcomes. How-
ever, a RCT would be required to establish this. Although in
previous studies the number of co-morbidities were reported
to have a significant influence on medication adherence [18,
19], this was not observed in the current study. These find-
ings might be influenced by the quality of the information
given by the patients. Identification of the influence of co-
morbidities would be subject to confounding as an under-
standing about co-morbidities relied on the patient’s
understanding of their clinical picture and a poor under-
standing would result in limited knowledge of their co-
morbidities. Hence this study is not designed to determine
the influence of co-morbidities as an independent predictor.
In addition, previous studies also reported that the com-
plexity of patients’ medications may influence patients’
adherence [20, 21]. The effects, however, were not observed
in the current study. Since more than one third of the patients
received compliance packs that helped to simplify their
medication regimen, the true effects of medication com-
plexity would be difficult to estimate independently.
The multilevel mixed effects logistic regression model
analysis found that predictors of good achievement in
medication knowledge were being: (1) female (2) non-

Maori (3) having a longer follow-up duration or (4) on a
short-term medication. Although the number of short-term
medications was shown to positively predict the good
achievement in medication knowledge score, the impor-
tance of this finding may not be significant in the clinical
setting or for patients on medications for chronic condi-
tions. A specific reason for women having a better
achievement in knowledge about medications could not be
identified. However a study by Burge et al. [22] reported
better medication knowledge was demonstrated to correlate
with higher levels of patient’s satisfaction, education and
confidence that they can take medication as prescribed.
Some of these factors may have contributed to our finding
that women have better achievement in medication
knowledge score but this information was not available.
Despite the fact the women appeared to have higher
knowledge scores than men this did not translate into
improved medication adherence scores.
Also consistent with the findings by Burge et al., the
current study indicated a possible correlation between
ethnic background and medication knowledge [22]. In their
study non-Latino patients were found to have a better
knowledge of medications than Latino patients, and eth-
nicity and background education were significantly related
to knowledge [22]. Previous studies also reported that
medication knowledge and adherence could be influenced
by poor health literacy [23, 24]. An earlier study conducted
in New Zealand found that people with Maori ethnicity
have poorer health literacy skills than non-Maori [25]. It is
possible that this may have contributed to the lower med-
ication knowledge score in Maori seen in this study.
The length of engagement in the program was shown to
influence all three scores: patients’ knowledge and per-
ceptions of, and adherence to medications. The logistic
regression models showed that patients who remained
engaged for longer were more likely to attain good
achievement scores overtime. This finding appeared inde-
pendent of gender and ethnicity. Erickson et al. [26] in their
study perceived that increased contact with pharmacists, in
addition to usual care from doctors, contributed to increase
patients’ knowledge and awareness of the importance of
medications therapy such as adherence. Frequent contact
between a pharmacist and patient increase pharmacists’
opportunities to improve patients’ level of knowledge and
understanding about their medications and disease, and
allows patients to get more involved in their medication
therapy [27]. This should help improve patients’ adherence
to their mediation [28]. As knowledge and involvement
increase, patients’ anxiety about disease and medication
should decrease, and their confidence to self-manage and
monitor their disease conditions will improve [29].
Although the score of patients’ knowledge, perceptions,
and adherence to medications improved in each visit (see
Table 3), only 15 % of patients in this study had four MUR
consultations. The majority (57.8 %) of the patients had
only two visits. The reasons for not continuing the services
were unknown as the information was not recorded. It may
be important to examine the reason for not continuing the
service to understand more about the current provision of
fee-for-services MUR. Possible reasons for not continuing
could be related to pharmacy services such as an increased
workload, difficulty retaining staff, low profit margins; or
patient factors such as patients’ health had improved, they
no longer use the medications, patients were not satisfied
with the service, or personal reasons. Future studies should
be conducted to examine the possible cause for not
continuing the consultations.
There are some limitations to this study. Firstly, the data
were collected through retrospective review of patients’
MUR consultation records. The limited data available in the
records may have influenced the number of variables
available for analysis. A future study with a prospective
study design would allow more variables to be quantified.
Secondly, the assessments of patients’ knowledge, percep-
tions of and adherence to medications were subjective
assessments by pharmacists based on patients own impres-
sions and the accuracy of these is unknown. A limitation of
self-reported adherence includes that it is subject to recall
bias [30] and patients may tend to overestimate their level of
adherence. A more detailed evaluation that included objec-
tive assessments would have made the findings more robust.
A further limitation of the current study is its inability to
determine the influence of financial hardship on adherence,
as data were not collected on this during the consultations.
Finally, the findings on the influence of Maori ethnicity on
medication knowledge outcome may be confounded by
pharmacy as the majority of the Maori patients were
recruited from a single pharmacy (see Table 2). Since it is
not possible to disentangle the effect of ethnicity from the
pharmacy, generalization to a wider Maori population may
not be appropriate. Further study in a larger and more geo-
graphically wide-spread population of MUR patients is
required to identify patient groups with poor medication
knowledge. The findings would help healthcare providers to
develop strategies to assist any such populations.
Conclusion
The study provides insight into the characteristics of MUR
services and outcomes for patients. The adherence support by
pharmacists during MUR appeared to potentially increase the
score of patients’ knowledge, perceptions of and adherence
to their medications. Several factors such as ethnicity were
found to predict these attributes but further study is required
to confirm the findings in a larger population.
