Learning Objectives

At the completion of this presentation, the audience will be able to:• Summarize the sentinel articles on clinical informatics and

patient safety• Explain the conflicting findings in the context of

sociotechnical fit• Formulate guidelines that reframe implementation of clinical

informatics in support of patient safety with the goal of mitigating unintended consequences


3

Errors and ADEs: IT tools can…

Improve communication Make knowledge more readily accessible Assist with calculations Perform checks in real time Assist with monitoring Provide decision support Require key pieces of information (dose, e.g.)


4

IT and nursing safety

Medication error – smart pumps Knowledge error – EBN (Evidence Based Nursing)

Procedural error – POC computing

(Point Of Care)

“the science and technologies involved in healthcare -- the knowledge, skills, care interventions, devices and drugs – have advanced more rapidly than our ability to deliver them safely, effectively, and efficiently”

Definitions

EMR (Electronic Medical Record) – the set of databases (lab, pharmacy, radiology, clinical notes, etc.) that contains the health information for patients within a given institution or organization

CDS (Clinical Decision Support) component - software that makes relevant information available for clinical decision-making (clinical data, references, clinical guidelines, situation-specific advice)

CPOE (Computerized Physician Order Entry) component – enables clinicians to enter orders (tests, meds, dietary, etc.)

CCR (Computerized Clinical Reminder) – just-in-time reminders at the point of care that reflect evidence-based medicine guidelines

EMR

Historical context - EMR

“Medicine ought to be using modern technologies in order to better share information, in order to reduce medical errors, in order to reduce cost to our health care system by billions of dollars... Within ten years, every American must have a personal electronic medical record.”

President George W. Bush

Remarks at American Association of Community Colleges Annual Convention - April 26, 2004

EMR in VHA – an early pioneer

CPRS (one component of VistA) was initially released in 1996; mandated nationally in 1999


11

CDS

June 13, 2006 - AMIA publishes Roadmap for National Action on Clinical Decision Support• Recommended a series of activities to

ensure that optimal, usable, effective clinical decision support is widely available to providers, patients, individuals where and when they need it to make health care decisions

14

CCRs as CDS

In VHA, CCRs are an important function of the EMR

Reduces reliance on memory and presents clinical guidelines at point of care


15

Studies at VHA

Effectiveness of CCRs related to• User interface/workflow problems• Increased workload• Time for documentation• Inapplicability of CCRs to practice• Limited staff training• More steps/longer to resolve = lower

adherence


16

CCRs at VHA

Barriers• Lack of coordination• Using reminders at an inopportune time• Limited flexibility• Poor interface usability

Facilitators• Limiting # of reminders at a site• Strategic location of workstation• Integrating reminders into workflow• Ability to document system problems and receive

feedback


17

CPOE

In 2005, only 4% of hospitals are in full compliance with CPOE; 17% have made good progress.

Government and larger teaching hospitals are more likely to have implemented CPOE.

CDS recommendations

Kuperman GJ, et al. Medication-related clinical decision support in CPOE systems: A review. JAMIA 2007;14:29-40.

• Implementation must be done thoughtfully, taking into account staff workflow and needs of the organization

• Create clear concise alerts with sufficient information and clear appropriate action -- a human factors challenge

• Don’t generate large number of unhelpful alerts. Use a combination of commercial rule sets, rules other organization have developed, and rules about best practice.

• Prioritize the CDS features to implement, as the list of features is long


22

CDS

Kawamoto K, et al. Improving clinical practice using CDSS: A systems review of trials to identify features critical to success. BMJ 2005doi:10.1136/bmj.38398.500764.8F (published 14 March 2005)

• Provide decision support automatically as part of workflow• Deliver decision support at the time and location of decision

making• Provide actionable recommendations• Use a computer to generate the decision support (improves

consistency and reliability)


23

CDS

Bates DW, et al. Ten commandments for effective clinical decision support: Making the practice of evidence-based medicine a reality. JAMIA 2003;10:523-530.

• Speed is everything• Anticipate needs and delivery in real time• Fit into the user’s workflow• Improve usability to enable doing the right thing• Offer alternatives rather than insist on stopping an action


24

CDS

Bates DW, et al. Ten commandments for effective clinical decision support: Making the practice of evidence-based medicine a reality. JAMIA 2003;10:523-530.

• Changing direction is easier than stopping (defaults, e.g.)• Simple interventions work best (single screen of info)• The more data elements requested, the less likely the

guideline will be implemented• Monitor impact, get feedback, and respond• Manage and maintain your knowledge-based system—keep

it up to date


25

CDS

What are priority targets (types of errors, specific meds) How can CDS reinforce current efforts to reduce ADEs How can CDS target additional types of potential ADEs Focus on areas of risk for patient harm Be realistic in readiness for adoption Have policies and consistent approach about guiding vs.

directing care Have MD leadership and involvement Review each application periodically Worry about nuisance alerting Ensure timely updates


26

CPOE

Bobb A, et al. The epidemiology of prescribing errors: The potential impact of CPOE. Arch Intern Med 2004;164:785 – 792.

• A CPOE with an advanced level of CDS is needed to prevent many of the prescribing errors with the greatest potential to lead to patient harm.

– Basic = drug-allergy, drug-drug interaction & duplicate therapy checking, basic dosing guidance, formulary decision support

– Advanced = dosing for renal insufficiency and geriatric patients, guidance for medication-related lab testing, drug-pregnancy and drug-disease contraindication checking

and importance of unintended consequences related to CPOE. JAMIA 2007;14:415 - 423.

• More/new work for clinicians– Reduce redundancy in info collection, display relevant info in

logical locations, reduce keyboarding• 72% said it was a moderate to very important issue

• Unfavorable workflow issues– Model clinical workflow wherever possible

• 87% said it was a moderate to very important issue

• Never ending system demands– Reassess quality assurance measures and user retraining



28

CPOE

Campbell EM, Sittig DF, Ash JS, Guappone KP, Dykstra RH. Ash JS, Sittig DF, Poon EG, Guappone K, Campbell E, Dykstra RH.

• Problems related to paper persistence– Paper is here to stay for utilitarian purposes (note jotting)

• Untoward changes in communication patterns and practices– As Del Baccaro wrote: CPOE does not replace talking!


• Negative emotions– Training and communication help



29

CPOE

Campbell EM, Sittig DF, Ash JS, Guappone KP, Dykstra RH. Ash JS, Sittig DF, Poon EG, Guappone K, Campbell E, Dykstra RH.

• Generation of new kinds of errors– Be thoughtful in interface design

• 9% not a problem; 47% said it was a moderate to very important issue

• Unexpected changes in power structure– Recognize and deal with it explicitly during planning – may

require re-negotiation of processes between groups• 36% not a problem; 29% less important; 36% said it was a moderate

to very important issue

• Overdependence on the technology– Plan for management of unexpected downtime

• 82% indicate as dependency increases, downtime gets worse

Technical systems have social consequences

Social systems have technical consequences

We don’t design technology, we design sociotechnical systems

To design sociotechnical systems, we must understand how people and technologies interact


34

Future research

To what extent does alerting impact clinical behavior and patient outcomes?

What is the optimal way to present alerts to prescribers?

How can clinicians’ sense of satisfaction with alerts and other DS be increased?

When does “alert fatigue” happen? Which member of the health care team—MD,

RN, PharmD, other—is the best recipient of an alert?
