What is Evidence Based Medicine

The most commonly used definition for EBM is that "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." provided by David Sackett et al in the 1996 article, " Evidence-Based Medicine: What it is and what it isn't" for BMJ. Full text here

The Center for Evidence Based Managment (CEBMa) recommends that researchers consider the following questions in regard to published research and evidence. The process of evaluating evidence is known as critical appraisal.

1. Is the evidence from a known, reputable source?

2. Has the evidence been evaluated in any way? If so, how and by whom?

3. How up-to-date is the evidence?

CEBMa offers tools to help appraise research studies in the form of Critical Appraisal Checklists; you can set up a free account to access these resources.

Center of Evidence Based Medicine: Study Designs

According to the Center of Evidence Based Medicine, study designs include:

A defined population (P) from which groups of subjects are studied

Outcomes (O) that are measured

Experimental and analytic observational studies also include:

Interventions (I) or exposures (E) that are applied to different groups of subjects

What is PICO?

PICO is a mnemonic used to aide the clinician or researcher in identifying the important parts of a well-defined clinical question. This question then provides the basis for a search of medical literature on the question topic.
