Evidence based medicine 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 and patient values and expectations. The best available evidence, moderated by patient circumstances and preferences, is applied to improve the quality of clinical judgments (1, 2, 3).
