Abstract
Objective:To compare the types and costs of drugs prescribed by resident and staff physicians treating patients with uncomplicated essential hypertension.
Design:Cross-sectional study, using a computer-based medical record database.
Setting:Primary care internal medicine clinic in a large teaching hospital.
Patients/participants:Hypertensive patients seen by ten postgraduate year-1 (PGY-1) and PGY-2 primary care internal medicine residents and four staff physicians practicing in the same clinic.
Measurements and main results:The types and costs of antihypertensive drugs prescribed for the patients treated by resident and staff physicians were compared. A larger proportion of patients of resident physicians than of staff physicians were treated with calcium channel blockers [19(15%) vs. 40(4%), p<0.001]; residents prescribed thiazide diuretics less frequently and beta-blockers more frequently than did staff physicians, although these differences were not significant. The estimated average wholesale price of antihypertensive drugs for patients cared for by residents was 35% higher than that for patients cared for by staff physicians ($0.73 vs. $0.54, p=0.048). This difference was not fully explained by differences in practice composition.
Conclusions:Resident physicians in this study selected more expensive medications to treat hypertension than did their faculty preceptors, even when differences in practice composition were considered.
