Informed consent: law, clinical reality, and the role of the family physician.

Informed consent is typically seen as most relevant to surgical and other invasive specialties. Although family physicians perform fewer high-risk procedures, they are nonetheless extensively involved in the informed consent process because of the comprehensive and continuing nature of the family physician-patient relationship. Family physicians have a particularly important role in helping their patients to understand what diagnostic or therapeutic alternatives are available. Family physicians have an independent role in the informed consent process, as well as a collaborative role in the context of consultation and referral. Legal rules that require disclosure of alternatives to the patient by the treating physician are examined in the context of the family physician's role as a coordinator of patient care. Practical suggestions regarding discussion of alternatives, extent of disclosure, coordination with consulting physicians, and encouragement of patients' participation in discussions are offered.
