Physician-patient communication in the primary care office: a systematic review.

The physician-patient interview is the key component of all health care, particularly of primary medical care. This review sought to evaluate existing primary-care-based research studies to determine which verbal and nonverbal behaviors on the part of the physician during the medical encounter have been linked in empirical studies with favorable patient outcomes.

We reviewed the literature from 1975 to 2000 for studies of office interactions between primary care physicians and patients that evaluated these interactions empirically using neutral observers who coded observed encounters, videotapes, or audiotapes. Each study was reviewed for the quality of the methods and to find statistically significant relations between specific physician behaviors and patient outcomes. In examining nonverbal behaviors, because of a paucity of clinical outcome studies, outcomes were expanded to include associations with patient characteristics or subjective ratings of the interaction by observers.
