Providing primary general medical care in university hospitals: efficiency and cost.

Data on efficiency, costs, and profits of 15 internal medicine outpatient group practices in university hospitals were collected for 9 months from interviews, a time-motion study, observations, and reviews of bills. Charges for a follow-up visit were about 25% higher than Medicare's allowable charges, but differed threefold across practices. Physicians spent more than half their allocated patient care or supervision time in other activities and 14% of nursing time was used for direct patient care. Visits to second- and third-year residents cost one half of those to faculty. Faculty supervision of second- and third-year residents was limited; it was, on average, 2 minutes per follow-up visit. Despite these inefficiencies, bad debts, and educational costs, practices appeared to break even financially. We conclude it is financially feasible for university hospitals to provide primary care to disadvantaged populations.
