Tool Specs

• What is it?– Cost– Feasibility– Complexity

• Summary of evidence

• Ideal uses– Target behaviors– Target barriers

Practice Guidelines

– The Beginning: AHCPR Guidelines– Currently: Produced by professional societies,

governmental agencies, expert panels– Evidence-based frameworks– Recommended behaviors implicit or explicit

– Conclusion: necessary, but not sufficient• Relate back to transtheoretical model, or cognitive theory

(knowledge/awareness must be present before action)

Practice Guideline Specs• What is it?

– Cost: person-hours– Feasibility: buy-in; participation– Complexity: varies

• Summary of evidence ineffective in isolation

• Ideal uses– Target behaviors single, simple actions– Target barriers knowledge/attitudes

• Conclusion: it’s all about ‘implementation’

• Assemble a multi-disciplinary Panel (1-2 mos)– IM, FP, EM, ID

• Use evidence-based principles to assess evidence (2-3 mos)– AHRQ; ACP-CEAS

• Obtain professional society input and/or endorsement (2-3 mos)– ACP; AAFP; ACEP; IDSA

• Write (and re-write) manuscript/documents (4 months)

• Gonzales R, Bartlett JG, Besser RE, Hickner JH, Hoffman JR, Sande MA. Principles of appropriate antibiotic use for treatment of nonspecific upper respiratory tract infections in adults: background. Clinical Practice Guideline, Part 2. Annals of Internal Medicine, 2001;134:490-494.

SUMMARY OF PRINCIPLES

• Don’t prescribe antibiotics for colds & URIs

• Don’t prescribe antibiotics for acute bronchitis when comorbidity is absent

• Limit antibiotics to adults with sinusitis symptoms lasting at least 1 week

• Limit antibiotics to adults with sore throat who have a positive test or clinical screen for strep

Practice Guidelines seem to be most effective…

• for acute care conditions

• when quality of evidence is superior

• when compatible with existing values

• when decision making complexity is low

• when desired performance/behavior is clearly understood

• when new skills or organizational support is not necessary for behavior change

The influence of intervention strategy and organisational factors on practice guideline effectiveness.

Effectiveness of Specific Intervention Components

BMC Health Services Research 2006;6:53

Effect Modifiers of CPG Implementation Strategies

• Readiness to change– time in practice; age

– perception of a gap between current and optimal practices

– motivation

• The “Messenger”– opinion leader; colleagues

• “Practice enabling” strategies– information systems

– team building/support staff

– standing orders

– computerized medical records

• Reinforcements– reminders; profiling

– financial incentives

– liability

SUMMARYCPG Interventions

• Development– identify clinician knowledge and behavior gaps– identify barriers to change– evidence-based “best practice”– quantify benefit of CPG compliance on system, practice and

patient– local input & endorsement

• Implementation– opinion leader; clinical champion– point-of-service reminders– feedback/profiling

Clinical Decision Support

Clinical Decision Support SpecsKawamoto K et al. BMJ 2005

• What is it? – “…any electronic or non-electronic system designed

to aid directly in clinical decision making, in which characteristics of individual patients are used to generate patient-specific assessments or recommendations that are presented to clinicians for consideration”.

– Manual or computer-assisted preventive care– CPOE

• Cost: low-medium if infrastructure in place• Feasibility: depends heavily on IT officer buy-in• Complexity: potential for high complexity

Implementation Options for Clinical Decision Support Systems

Implementation Options for Clinical Decision Support Systems

Results of Meta-Regression of 71 studies. Kawamoto et al. BMJ 2005.

Clinical Decision Support SpecsKawamoto K et al. BMJ 2005

• Summary of evidence:– Automatic provision of support in clinical work-

flow strongly predicts success– Real-time decision support; recommendations

(not just assessments); and use of computers also predict success

– Simple prompts better than advanced systems• Ideal uses

– Target behaviors: management > diagnosis, especially drug-dosing and prevention

– Target barriers: doctors too busy; low priority problem

• Conclusion: key features of CDSS need to make system easy for doctors to use

Audit and Feedback

Audit and Feedback Specs-Jamtvedt G et al. Qual Saf Health Care 2006;15:433-6.

• What is it? – “any summary of clinical performance of

healthcare over a specified period of time”– Profile at individual, group or regional

level• Cost: fairly low depending on data source• Feasibility: not feasible for complex tasks;

ideal for testing, prescribing, referrals, procedures

• Complexity: low; acknowledge limitations of administrative data and inclusion criteria

Audit and Feedback Specs-Jamtvedt G et al. Qual Saf Health Care 2006;15:433-6.

• Summary of evidence:– Alone: mild-to-modest effect– In Combination: modest-to-strong effect

• Ideal uses– Target behaviors: test ordering; prescribing– Target barriers: doctors too busy; low

priority problem

• Conclusion: use in combination with education, outreach, reminders

Public and Patient Education

Consumer Education: Lots of Options!

• type of instructional media– verbal, written, audiotapes, audiovisual, computer-

assisted instruction

• type of learning activity– lecture, discussion, demonstration, practice,

interactive vs. non-interactive

• nature of follow-up– reminders, self-monitoring, support groups, feedback,

reinforcement, written action-plan

• degree of structure– planned instruction vs. unstructured information

• nature of content

Patient Education-Bottom Line

Search Strategy:

<insert disease here> and “patient education” and “randomized clinical trial”

Patient Decision Aids

Patient Decision Aid SpecsO’Connor AM et al. Cochrane Reviews 2003

• What is it? – An adjunct to counseling that

• explains options• clarifies personal values for the benefits vs. harms• guides patients in deliberation and communication

– Decision Quality• Decisions are informed (knowledge; risk perception)• Decisions based on personal values (congruence)’

– Most common conditions… most are web-based:• Breast, prostate and colon cancer screening & treatment• Menopause options• Cardiovascular disease management• Prenatal testing

Patient Decision Aid SpecsO’Connor AM et al. Cochrane Review 2003

• Cost: development… low-medium—person-hours• Feasibility: very feasible• Complexity: potential for high complexity • Summary of evidence:

– Most RCTs measured process/intermediate outcomese (knowledge; realistic expectations; decisional conflict)

• Main effects are on knowledge and realistic expectations, with OR about 1.4-1.6.

• Reductions in decisional conflict appear modest• 5/9 studies showed improvement in satisfaction with decision

• Ideal uses– Target behaviors: health care decisions that depend on

patient preferences for harms/benefits of different options– Target barriers: poor patient knowledge; doctors too busy;

low priority problem• Conclusion:

CONCLUSIONS

• Multidimensional Intervention IS effective at reducing overuse of antibiotics in EDs.

Metlay et al, Ann Emerg Med, 2007.

SUMMARY

• Uncommon to have any single tool prove >10% effect… thus, use multifaceted implementation strategies

• Guidelines/Knowledge necessary starting point, but rarely sufficient– Nicely augmented by performance feedback, opinion

leaders, and reminders– Consider adding patient education when appropriate

• Decision aids can be very useful, particularly when at point of service/decision making
