Clinical guidelines: a must for rheumatology?

Clinical guidelines are sets of recommendations, backed by medical evidence, to aid physicians in patient-care decisions. There has been a proliferation of practice guideline development in all fields of medicine, including rheumatology. This chapter will discuss the need for guidelines in rheumatology, the methodology of guideline development, validation and implementation, the various guidelines published in rheumatology, and the role of the rheumatologist in guideline development. Clinical guidelines can serve to inform practitioners of the latest medical evidence and minimize harmful practice variation. Guidelines must rely on good evidence to be credible to the medical community, yet there are still many barriers to guideline acceptance by practitioners. The theories behind guideline development and validation are well described, although not always practised. Guideline dissemination and implementation methods are still being explored. It remains unclear how best to implement guidelines and convince physicians to accept and incorporate evidence-based recommendations into their practice.
