Abstract

Evidence-based medicine (EBM) is the conscientious, explicit, and judicious use of current best evidence in making decisions regarding the care of individual patients. This concept has gained popularity recently, and its applications have been steadily expanding. Nowadays, the term "evidence-based" is used in numerous situations and conditions, such as evidence-based medicine, evidence-based practice, evidence-based health care, evidence-based social work, evidence-based policy, and evidence-based education. However, many anesthesiologists and their colleagues have not previously been accustomed to utilizing EBM, and they have experienced difficulty in understanding and applying the techniques of EBM to their practice. In this article, the author discusses the brief history, definition, methods, and limitations of EBM. As EBM also involves making use of the best available information to answer questions in clinical practice, the author emphasizes the process of performing evidence-based medicine: generate the clinical question, find the best evidence, perform critical appraisal, apply the evidence, and then evaluate. Levels of evidence and strength of recommendation were also explained. The author expects that this article may be of assistance to readers in understanding, conducting, and evaluating EBM.
