Physicians, physicians' assistants, and the social characteristics of patients in southern Appalachia.

A focus on health care delivery systems and the emergence of New Health Practitioners, particularly Physicians' Assistants (PAs), represents one of the more significant nonbiomedical developments in American medicine since World War II. Much discussion about PAs revolves around the kinds of illnesses they are qualified to treat which then permits physicians to concentrate on patients with other types of illnesses. Ignored in this focus on illness characteristics is the possibility that physicians and PAs may treat patients with different social characteristics. That issue is the topic of this paper. Differences between the status characteristics of physician and PA patients are reported for a rural community where PAs and physicians work side by side in the same offices. The relationships observed in this rural community suggest that the higher a patient's socioeconomic status, the more likely (s)he is to be treated by the physician.
