Guidelines for medical practice: 2. A possible strategy.

The recognition that much current medical practice is based on incomplete scientific evidence has led to calls for the generation of guidelines for optimal patterns of practice. These guidelines must be developed from a synthesis of existing scientific data ideally obtained from randomized clinical trials. However, at present we may have to rely on less satisfactory data and the views of experts in the field. The primary purpose of these initiatives must be to improve patient care. The Ontario Medical Association has made recommendations on how such guidelines should be produced, and in a recent survey a substantial majority of family physicians supported them. There is general agreement that the coordinating body should be independent of government and other interested parties. In addition, the medical profession must have the primary role, and a number of medical organizations should also be represented. We propose a possible structure for a group charged with developing guidelines for medical practice at a provincial level and on an experimental basis. Recommendations are made on its membership, function and relationship with other organizations. The identification and diffusion of justifiable, scientific practice patterns will help reduce waste of scarce resources, maintain the role of the profession as guardian of the quality of care and ultimately benefit the patient.
