EBP - Process Frohna JG, Park SM, Pituch KJ. Integrating Evidence- Based Medicine into The Curriculum. May 2003. Dept. of Pediatrics, University of Michigan.
What is Evidence- Based Practice? Decision based on all three components Patient preferences Clinical expertise Research evidence Frohna JG, Park SM, Pituch KJ. Integrating Evidence- Based Medicine into The Curriculum. May 2003. Dept. of Pediatrics, University of Michigan.
Why is EBP important? Traditional sources can be inaccurate or out-dated Blindly following ‘expert’ opinion not ideal Allows us to recognize the strength of evidence behind recommendations Sackett et al. Evidence –Based Medicine How to Practice and Teach EBM 2ndEd. 2000
EBP Not a fad Not blind application of evidence to all patients Not “Cookbook Medicine” Not blind application of evidence to all patients Conscientious use of evidence- integrated with clinical expertise and patient values Not a fad Frohna JG, Park SM, Pituch KJ. Integrating Evidence- Based Medicine into The Curriculum. May 2003. Dept. of Pediatrics, University of Michigan.

How to Find Summarized Evidence Cochrane Database of Systematic Reviews Cochrane Register of Controlled trials Database of abstracts of Reviews Clinical queries Clinical evidence Limit to meta-analysis Secondary journals Guidelines
