1 Translating Evidence into Practice Danny Liew Melbourne EpiCentre Medical Unit 1

2 Application of Evidence in Practice education and training access to, and interpretation of, evidence identifying and overcoming barriers culture change outcomes research: ‘practice-based evidence’

3 Overview (the problem with) evidence-based practice outcomes research –comparative effectiveness research –health technology assessment

4 Evidence-Based Practice

5 Efficacy vs Effectiveness efficacy: intervention ‘works’ in a research (clinical trial) setting effectiveness: intervention ‘works’ in the real-life setting often a large gap

6 circumscribed populations focus: benefit >> harm artificial environment short-term ?competing morbidity and mortality ?costs Clinical Trial vs Real-Life Settings
