Evidence-based medicine (EBM) is an approach to medical practice intended to optimize decision-making by emphasizing the use of evidence from well-designed and well-conducted research.Although all medicine based on science has some degree of empirical support, EBM goes further, classifying evidence by its epistemologic strength and requiring that only the strongest types (coming from meta-analyses, systematic reviews, and randomized controlled trials) can yield strong recommendations; weaker types (such as from case-control studies) can yield only weak recommendations.In 1995 Rosenberg and Donald defined individual level evidence-based medicine as "the process of finding, appraising, and using contemporaneous research findings as the basis for medical decisions." In 2010, Greenhalgh used a definition that emphasized quantitative methods: "the use of mathematical estimates of the risk of benefit and harm, derived from high-quality research on population samples, to inform clinical decision-making in the diagnosis, investigation or management of individual patients." highlight important differences in how evidence-based medicine is applied to populations versus individuals.When designing guidelines applied to large groups of people in settings where there is relatively little opportunity for modification by individual physicians, evidence-based policymaking stresses that there should be good evidence to document a test´s or treatment´s effectiveness.Medicine has a long tradition of both basic and clinical research that dates back at least to Avicenna Called "clinical judgment" and "the art of medicine", the traditional approach to making decisions about individual patients depended on having each individual physician determine what research evidence, if any, to consider, and how to merge that evidence with personal beliefs and other factors.In the case of decisions which applied to groups of patients or populations, the guidelines and policies would usually be developed by committees of experts, but there was no formal process for determining the extent to which research evidence should be considered or how it should be merged with the beliefs of the committee members.The pertinent evidence must be identified, described, and analyzed.

Between 19, the Evidence-based Medicine Working Group at Mc Master University published the methods to a broad physician audience in a series of 25 "Users’ Guides to the Medical Literature" in JAMA.

It promotes programs to teach the methods to medical students, practitioners, and policy makers.

In its broadest form, evidence-based medicine is the application of the scientific method into healthcare decision-making.

In the autumn of 1990, Gordon Guyatt used it in an unpublished description of a program at Mc Master University for prospective or new medical students.

In 1996, David Sackett and colleagues clarified the definition of this tributary of evidence-based medicine as "the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. [It] means integrating individual clinical expertise with the best available external clinical evidence from systematic research." while respecting the fact that practitioners have clinical expertise reflected in effective and efficient diagnosis and thoughtful identification and compassionate use of individual patients' predicaments, rights, and preferences.
