Guidelines for medical practice: 1. The reasons why

Abstract

Various external special interest groups are promoting attempts to better measure and control the performance of the medical profession, primarily to restrain costs. We can neither afford to ignore the rising costs nor reject efforts by provincial licensing authorities to improve supervision of the quality of care. Furthermore, there is increasing public interest in the outcome of medical treatment and a suspicion that some care may be unnecessary or inappropriate. Much of what physicians do is not based on impeccable or complete scientific evidence, and we have not established a method whereby science can consistently be translated into practice. Optimal practice patterns must be defined to improve the quality of care and to maximize the efficiency with which scarce resources are used. Careful scientific evaluation of data is particularly necessary with the arrival of new drugs and technology. Sensible, flexible guidelines produced by appropriate panels will help promote improved practice. Rigid standards must be avoided to allow for individual consideration and scientific innovation. The recognized difficulties of influencing clinical practice by precept or education and the problems imposed by rapidly changing scientific knowledge are two hurdles to be overcome. Licensing bodies must identify and enforce minimal standards, but optimal practice patterns are better devised by a broader segment of the profession. Intervention by third-party payers, as is prevalent in the United States, intrudes upon physician autonomy and reduces access to care. Physicians must support the development of guidelines for optimal medical practice based on the best existing data and focused on improving the quality of care.
