Social Work: Evidence-Based Practice: Evidence-Based Practice

What Is Evidence-Based Medicine [Practice]?

Levels of evidence pyramid ("Information Mastery: Navigating the Maze." University of Virginia, Claude Moore Health Sciences Library, 2009.)

Evidence based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients. The practice of evidence based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research."

P.I.C.O. Model

Patient, Population, or Problem: How would I describe a group of patients similar to mine?

Intervention, Prognostic Factor, or Exposure: Which main intervention, prognostic factor, or exposure am I considering?

Comparison or Intervention (if appropriate): What is the main alternative to compare for the intervention?

Outcome you would like to measure or achieve: What can I hope to accomplish, measure, improve, or affect?

Levels of Evidence

Quality of Evidence ranges from A (High) - several high-quality studies with consistent results - to D (very low) - expert opinion, no direct research evidence, or one or more studies with very severe limitation
