Evidence-based Practice

Evidence-based medicine (EBM) is the integration of best research evidence with clinical expertise and patient values.
Guyatt, G et al. A new approach to teaching the practice of medicine. JAMA 1992;268:2420-2425


Where to Search for Evidence

Using the Literature in Practice

Convert need for information into clinical question

Find the best evidence

Critically appraise the evidence

Integrate evidence with clinical expertise and client values

Evaluate the process: how did it work for this patient?

Using PICO to Formulate Clinical Questions

PICO (alternately known as PICOT) is a mnemonic used to describe elements of a good clinical question. It stands for:

P: Patient/Population/Problem
I: Intervention
C: Comparison
O: Outcome

Many people find that the PICO process helps them clarify their question, which in turn makes it easier to find an answer. 

Use PICO to generate terms - you'll use some of the terms in your literature search for the current best evidence, and you'll use them in evaluating the information you do find.

Levels of Evidence
