"Evidence-based medicine (EBM) is 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.“2
Short definition: “the integration of best research evidence with clinical expertise and patient values.”3

Since EBM’s focus in on patient-oriented, outcomes-based
research as opposed to expert led medicine, the medical literature is searched and evaluated to determine what data is available that addresses questions that arise in clinical practice.

The professionally sponsored literature for medical practitioners acts as though each practitioner in each American community were supposed to be his own scholarly and scientific institute, screening, sifting, evaluating, assessing, and translating into practical terms the output of medical research that is reported in the periodical literature…The practitioner of course, is quite unable to live up to this myth. For that reason, he is likely to have recourse…to those sources that are willing to offer him the digested and preselected information that meets the needs.
Herbert Menzel, 1966
In a set of journals pertinent to primary care physicians in 2002: 7,287 articles are published monthly.
A physician trained in epidemiology would take an estimated 627.5 hours per month to evaluate articles pertinent to his practice.1
