Differences between family physicians' and general internists' medical charges.

OBJECTIVES Data from 509 primary care patients were analyzed to determine whether practice style differences between family physicians and general internists generate differential utilization of health care resources leading to differential medical charges. METHODS New adult patients were prospectively randomized to care by family physicians and general internists. Utilization of medical care services and associated charges then were monitored for 1 year of care. RESULTS Family practice patients had a significantly higher mean number of visits to their primary care clinic and significantly fewer emergency room visits than patients assigned to Internal Medicine. Mean charges for primary care and emergency department treatment were significantly lower for patients assigned to Family Practice than for those assigned to General Internal Medicine. There were no significant differences in charges for specialty clinic visits, hospitalizations, or diagnostic services. CONCLUSIONS Practice style differences between family physicians and general internists were associated with differential medical charges, with family physicians generating lower charges for some aspects of care.
