2 Translating research into evidence-based care is difficult! Consistent finding of a gap between research and practice McGlynn et al found that patients in the USA received 55% of recommended care, with similar findings globally 20-30% of patients may get care that is not needed or care that is potentially harmful In Australia, an analysis of a sample of health care encounters showed Adults received appropriate care at 57% (95% CI 1%- 43%) of encounters Varied considerably by condition Grimshaw et al 2012 Implementation Science Gap between discovery and patient care.

3 Overall goals of the presentation A super-quick introduction to implementing evidence Tools, tips, and traps to consider at each step 22 July

4 From the literature to evidence-based care 1. Knowledge for translation Systematic reviews: why translate bodies of evidence? Tools that provide accessible, decisionrelevant information from research: guidelines, clinical decision support, decision aids for patients Appraising bodies of evidence: GRADE, AGREE 2. Evidence-based implementation approaches Systematic reviews of quality improvement and continuing professional education approaches Interpreting other study designs when there isn t a systematic review 3. Implementing changes to care Understanding and addressing barriers and facilitators of change Assessing the impact of implementation efforts 22 July

5 Knowledge to action Graham, J Eval Clin Pract 2006, 26: July

7 Knowledge for translation Primary research Single studies (e.g. trials, observational studies) Analysis of safety & quality data Analysis of individual, local, regional or national data can be used to: Identify variation in care (possible areas for quality improvement) Monitor the impact of introducing changes to care Graham, J Eval Clin Pract 2006, 26: July

8 Knowledge for translation Primary research Single studies (e.g. trials, observational studies) Analysis of safety & quality data Systematic reviews Synthesis of individual studies (with or without meta-analysis) Uses all available evidence Graham, J Eval Clin Pract 2006, 26: July

9 Knowledge for translation Primary research Single studies (e.g. trials, observational studies) Analysis of safety & quality data Systematic reviews Synthesis of individual studies (with or without meta-analysis) Uses all available evidence Using findings from systematic reviews: Increases certainty about the effects of an intervention Helps identify bias in the conduct of studies; reduces the chance you will be misled Provides evidence for individualising care through exploration of whether the effects of the intervention vary in patient subgroups Saves time (searching, appraisal, synthesis is done for you).

11 Acknowledgement for slide: Prof Sally Green Why translate bodies of evidence not results of individual studies? Results of individual studies need to be interpreted and translated alongside the body of evidence Single studies rarely provide sufficient evidence for practice change (especially small studies in specific populations) Early results can lessen over time studies require replication and synthesis Your Health Net: Developed by CHCP 22 July

13 Of 49 highly cited studies, 45 claimed the intervention was effective. Of these: 7 (16%) were contradicted by subsequent studies 7 (16%) found stronger effects than subsequent studies 20 (44%) were replicated by subsequent studies 11 (24%) remained largely unchallenged Of those where subsequent studies contradicted or showed weaker effects than the highly cited study: 5/6 were non-randomised studies 9/39 were randomised trials 22 July

17 Knowledge for translation Primary research Single studies (e.g. trials, observational studies) Analysis of safety & quality data Systematic reviews Synthesis of individual studies (with or without meta-analysis) Bodies of evidence Tools for translation Resources that provide accessible, decision-relevant information from research e.g. evidence-based guidelines, decision-support for clinicians, patient decisions aids & information Graham, J Eval Clin Pract 2006, 26:13-24 Relevance to decision-making 22 July

18 Knowledge tools & products 1. Guidelines for clinical practice 2. Decision support tools for clinicians at point of care 3. Patient decision aids & information 22 July

19 Tools for guidelines For rating the quality of the evidence underpinning guideline recommendations Used to summarise findings from systematic reviews Support interpretation of findings (faster, easier) For appraising the guideline development process Useful if you are considering using an existing guideline 22 July

21 See Quality of evidence based on 5 domains: 1. Risk of bias 2. Indirectness (e.g. relevant population, intervention, comparator, outcomes) 3. Inconsistency (statistical heterogeneity: studies have non-overlapping confidence intervals, I 2, Chi 2 ) 4. Imprecision (uncertainty: wide confidence intervals, small number of participants in pooled sample) 5. Publication bias (reporting bias detected statistically, or suggested because small studies consistently report effects favoring the intervention) 22 July

25 Evidence based implementation approaches Quality improvement and continuing professional development (practical efforts to improve care, using local knowledge, research-based evidence or both) 22 July

26 Evidence based implementation approaches Terms used in the literature: translating (research, evidence, knowledge..) into practice implementing (research, evidence, knowledge..) in practice practice (behaviour) change knowledge to action Increasing recognition that methods used for QI & CPD need to be supported by evidence of their effectiveness Substantial opportunity cost in investing in ineffective strategies 22 July

29 Designs (experimental) Randomised designs Individually randomised Cluster randomised Stepped wedge cluster randomised Other designs Non-randomised designs Uncontrolled before and after studies Controlled before and after studies Interrupted time series 22 July

30 Designs (experimental) Randomised designs Individually randomised Interpret with caution: can t exclude the possibility that observed Cluster effects randomised are due to factors other than the intervention (e.g. changes over time, differences between the control and intervention groups) Stepped wedge cluster randomised Non-randomised designs Uncontrolled before and after studies Controlled before and after studies Interrupted time series 22 July

40 Knowledge to action Using knowledge of barriers/ enablers + evidence-based strategies to address Graham, J Eval Clin Pract 2006, 26: July

41 Key messages What to implement: Where possible, implement findings from a body of evidence (systematic reviews, overview of systematic reviews) OR Use guidelines or tools based on systematic reviews Use GRADE to assess the body of evidence and AGREE to assess the quality of the guideline development process How to implement: Consider (and assess) the barriers and enablers to changing practice Select evidence-based strategies to target these barriers and enablers Consider carefully the opportunity cost of using strategies that aren t yet supported by high quality evidence 22 July
