Evidence-Based Medicine Algorithm

The Evidence-Based Medicine Algorithm was created to help identify the best sources to answer a clinical question and to help with efficient literature searching.

Evidence-Based Medicine (EBM) has been defined as: "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" David Sackett, et al. Evidence Based Medicine: What It Is and What It Isn't," BMJ 312, no.7023 (1996).


Steps of the Algorithm

1) Begin with an answerable clinical question. The PICO model can help you form answerable clinical questions.

2) Follow the Algorithm - Flowchart to help with efficient literature searching.

The flowchart groups resources into tiers based on their authority as the best evidence for clinical decision making. While the higher tiered resources provide more distilled information, the range of subjects available is more limited than the lower tiers. The specific clinical question being asked will help determine the most appropriate resources and tiers.
