Using techniques from science, engineering, and statistics, such as meta-analysis of medical literature, risk-benefit analysis, and randomized controlled trials,<unk>  aims for the ideal that healthcare professionals should make "conscientious, explicit, and judicious use of current best<unk> " in their everyday practice.
Generally, there are three distinct, but interdependent, areas of<unk> . The first is to treat individual patients with acute or chronic pathologies by treatments supported in the most scientifically valid medical literature. Thus, medical practitioners would select treatment options for specific cases<unk>  on the best research for each patient they treat. The second area is the systematic review of medical literature to evaluate the best studies on specific topics. This process can be very human-centered, as in a journal club, or highly technical, using computer programs and information techniques such as data mining. Increased use of information technology turns large volumes of information into practical guides. Finally,<unk>  can be understood as a medical "movement" in which advocates work to popularize the method and usefulness of the practice in the public, patient communities, educational institutions, and continuing education of practicing professionals.<unk>  has demoted ex cathedra statements of the "medical expert" to the least valid form of<unk> . All "experts" are now expected to reference their pronouncements to scientific studies.
