A comparison of clinical performance of primary care and traditional internal medicine residents.

OBJECTIVE

To compare primary care and traditional Internal Medicine residents in their adherence to preventive medicine guidelines, performance in the management of chronic diseases, and utilization of resources.

DESIGN

Prospective cohort study.

SETTING

Urban Internal Medicine residency program.

PARTICIPANTS

Sixteen primary care and 137 traditional Internal Medicine residents who took care of 6,307 patients (a total of 21,002 patient visits in a 1-year period).

MEASUREMENTS

Adherence to preventive medicine guidelines for the screening of breast cancer, cervical cancer, hypercholesterolemia, and colon cancer; admission rates among patients with asthma, chronic pulmonary disease, and diabetes mellitus; four items in the management of diabetes; and resource utilization including the costs for laboratory and radiology tests and number of consultations.

RESULTS

Primary care residents, as compared with traditional residents, adhered to preventive medicine guidelines for a greater proportion of their patients for the following: breast cancer among women aged 52 to 75 years (61% vs. 54%, respectively, P = 0.05); cholesterol screening among patients aged 20 to 64 years (39% vs. 33%, P = 0.007); colon cancer among patients older than 50 years (49% vs. 31%, P = 0.001); and cervical cancer among women aged 20 to 64 years (36% vs. 31%, P = 0.03). There were no differences in hospital admission rates for patients with diabetes or asthma. Total ambulatory care costs for tests, procedures, consults, and office visits were greater for patients of primary care residents ($1,045 vs. $899, P = 0.0001), although total costs per primary care visit were similar between the two patient groups.

CONCLUSIONS

Primary care residents more closely adhered to preventive medicine guidelines but were similar to traditional residents in their management of chronic diseases. Patients of primary care residents had greater ambulatory care costs that were not entirely attributable to greater adherence to preventive medicine guidelines.
