Evidence-Based Medicine

 

Key Points:

  • Evidence-based medicine (EBM) is "the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients."
    • Sackett DL, Rosenberg WMC, Muir Gray JA, Haynes RB, Richardson WS. Evidence-based medicine: what it is and what it isn't. BMJ. 1996;312:7172.
  • Effectively evaluating medical literature is an essential physician skill since the answer to many clinical questions are constantly evolving.
  • Successfully utilizing evidence medicine involves several steps:
    • Defining the question
    • Finding the evidence
    • Assessing the evidence
    • Applying the evidence
    • Effectively communicating the information 

 

Objectives:

  • Effectively assess the validity of medical literature including both therapy and diagnosis articles
  • Define and apply the following terms when assessing medical literature: sensitivity, specificity, likelihood ratios, pre-test probability
