Although some patients may prefer to see a physician of the same race, ethnicity, or sex, empirical evidence that this form of concordance alone improves the quality of interpersonal or technical care is, at best, mixed (2–7). In a carefully designed, multimethod study, for example, Cooper and colleagues (2) found that although patients were more satisfied when seen by physicians of the same race, actual audiotapes of their visits showed no increase in patient-centered communication compared with the audiotapes of visits in which the patient's race differed from the clinician's race. Earlier research suggests that minority patients seeing nonminority physicians may actually be more actively involved in treatment decisions than when the physician's race is the same as the patient's race (7). Greater diversity in the physician workforce is essential. However, the evidence suggests that relying on racial concordance to resolve communication problems between physicians and patients is unlikely to improve quality of care substantially.
