[Clinical practice guidelines (I): elaboration, implementation and evaluation].

Clinical practice guidelines are defined as a set of systematically developed recommendations that aim to guide the decision-making process. In the last ten years, interest in clinical practice guidelines has grown steadily as they have enabled a point of encounter between research and clinical practice. Unlike classical protocols, usually based on consensus or opinion and a narrative review of the available scientific literature, clinical practice guidelines are developed by multidisciplinary teams, review the evidence exhaustively and systematically, evaluate the quality of the information, and propose specific recommendations in line with the quality and design of the studies available. The later stages of dissemination, implementation, and posterior evaluation of their impact complete the cycle for dynamic change in clinical practice.
