Evidence-based medicine


Evidence-based medicine is "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients."[1] Alternative definitions are "the process of systematically finding, appraising, and using contemporaneous research findings as the basis for clinical decisions"[2] or "evidence-based medicine (EBM) requires the integration of the best research evidence with our clinical expertise and our patient's unique values and circumstances."[3] Better known as EBM, evidence based medicine has roots in clinical epidemiology and the scientific method, and emerged in the early 1990's in response to discoveries about variations and deficiencies[4] in medical care to help healthcare providers and policy makers evaluate the efficacy of different treatments.
