Transferring results of research into clinical practice and their effective use for decisions in health care have become a major concern and are pivotal to quality improvement. Among the tools that have been developed are clinical practice guidelines (CPG). Developing reliable and valid recommendations requires a rigorous methodological approach that combines a systematic review of the results of clinical research with expert, pondered and explicit judgment. Guaranteeing applicability and implementation of these recommendations implies asking the question of how acceptable the recommendations are for the patient, the availability of the procedure and the expertise necessary in the specific context as well as identification of the organizational impact when put into action. CPG are a source of information not only for physicians but also for policy makers, insurance institutions, continued education programs and production of information for high quality decision making for patients.
