A study of physicians' assistants in a rural setting.
In an effort to improve the health care in a rural county in Southern Appalachia, physicians' assistants (MEDEX) have been employed in the offices of three general practitioners over a three-year period. This program was evaluated using a before-after and experimental-control (county) design, utilizing data both from physician office contracts and a continuing survey of the populations of the experimental and control counties. Results show the following: 1) utilization (average office visits per week) increased; 2) types of care (preventive versus curative) remained stable; 3) the hospitalization rate increased continuously during the three years for those physicians using physicians' assistants; and 4) the physicians' assistant functioned more as a physician substitute than as an assistant. It is concluded that although use of physicians' assistants may increase utilization rates, they may not reduce the long-range cost of medical care through providing more preventive or ambulatory (as opposed to hospital) care.
