Purpose Show how to use health- evidence.ca to search for and incorporate review evidence into decision making
Agenda 1. What is evidence-informed decision-making? 2. Types of evidence 3. Evidence sources 4. Searching
What is EIDM?• EIDM involves integrating the best available research evidence into decision – making define question search & appraise context apply Evidence-informed decision
Value of EIDM in Public Health • Create effective and appropriate policies, programs and activities for our communities and target populations • Do what works and don’t do what does not work!
Need for EIDM in Public Health • Acute and Primary Care – Consistent evidence of failure to translate research findings into practice • Ontario Public Health Standards – Research and knowledge exchange
Model of EIDM in Public Health Research Evidence National Collaborating Centre for Methods and Tools Haynes B, DiCenso, A., Ciliska D., & Guyatt, G. 2005
EIDM Process Decision Assess applicability Interpret Appraise the quality Search for evidence Define the question
Define the Research Question Define the question Population (or situation) Intervention (or exposure) Comparison (or group) Outcome(s) Time (when or how quickly)
Search for Research Evidence Search for evidence DiCenso, Bayley, & Haynes, 2009
Systematic Review • A synthesis or summary of single studies • A formalized scientific process • Multiple reviewers involved
Example ScenarioYou are are on the school health team in a publichealth unit and the lead contact with a local schoolboard. A board program to require school-based dailyphysical activity is being implemented and the boardhas asked you to help make the case for daily physicalactivity to support their presentation to principals,teachers and parents. You are aware that obesityamong children is a health issue in your jurisdiction.You would like to find out and advise the board aboutwhether the new physical activity levels will be moreeffective in preventing/ decreasing obesity comparedto physical activity currently implemented in schools.
Research Question Example 1• Population – school children 8-14 yrs• Intervention – school-based physical activity• Comparison – no physical activity• Outcome – obesity Q: Is 30 minutes of daily school-based physical activity effective in decreasing obesity in children aged 8 – 14 yrs. compared to existing physical activity levels?
Small Group Task30 minutes:• Generate a scenario from your own work• Using PICO framework, develop a research question
