What is evidence-based practice?

Evidence-based Practice

Process by which clinical decisions are made using:

Best available research evidence

Clinical expertise

Patient preference

Historical Perspective

Variation in practice leads to:

Variable quality of care

Higher cost of care

Potential for errors that may cause harm

Translating research into practice

Skills Required for EBP

Clearly identify practice problem or new knowledge ( innovation)

Find research literature

Critically evaluate research findings

Apply to practice through change process

Identifying Practice Problem

Why are we doing this?

Why are we doing it this way?

Can we produce better outcomes with greater consistency?

Clinical practice problems in your setting?

Critically Evaluating Research

Literature review

Integrative literature review

Application to Practice

Does the research apply to my patient population?

Would this practice change improve process of care? Patient outcomes?

Is there support for this practice change?

EBP Models

CURN project Research utilizationReview, synthesis, application, evaluation

Stettler Model of Research UtilizationCritical thinking & decision making

Iowa Model of Research in PracticeQuality assurance meets research utilization

Planned Change

Assess current practice (processes and outcomes)

Identify and implement changes to modify processes

Evaluate effects on processes and/or outcomes
