Abstract

Evidence-based medicine (EBM) is the application of current, best-available clinical evidence to health care decisions for individual patients. EBM consists of five major steps: asking a clinical question, systematic retrieval of the best-available evidence, critical appraisal of the evidence, application of results, and evaluation of performance. This systematic approach allows the clinician to assess and grade the validity of a study and its applicability to the clinical question at hand. A sound knowledge of study design and study bias helps the clinician astutely evaluate the literature and design a study of his/her own. The five steps of EBM, categorizing and grading evidence, and major principles of study design are discussed in this chapter.
