Definition

Evidence based medicine (EBM) was originally 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.
(Sackett DL, Rosenberg WMC, Gray JAM, Haynes RB, Richardson WS. Evidence based medicine: what it is and what it isn't. BMJ 1996; 312: 71-2)

The revised and improved definition of evidence-based medicine is a systematic approach to clinical problem solving which allows the integration of the best available research evidence with clinical expertise and patient values.
(Sackett DL, Strauss SE, Richardson WS,et al. Evidence-based medicine: how to practice and teach EBM. London: Churchill-Livingstone,2000)

Evidence-Based Practice is defined as, "Making a conscientious effort to base clinical decisions on research that is most likely to be free from bias, and using interventions most likely to improve how long or well patients live." 
(Mark H. Ebell, MD, MS, Professor, University of Georgia, Editor-in-Chief, Essential Evidence Plus)

Ask, Acquire, Appraise, Apply

  1. Ask patient-oriented, relevant, answerable questions about the health status and context of patients or populations 
  2. Acquire the best available evidence to answer the question 
  3. Appraise the evidence critically for validity and applicability to the problem at hand
  4. Apply the evidence by engaging in collaborative health decision-making with the patient(s) or population(s)
