Current health care reform is placing primary care physicians in an in
creasingly significant role as the front-line providers of women's hea
lth care. It is critical that primary care physicians as well as surge
ons develop the knowledge base, physical examination skills, and inter
personal skills necessary to care for patients with breast cancer. Thi
s study uses a standardized patient breast case in an Objective Struct
ured Clinical Examination (OSCE) format to objectively assess clinical
breast evaluation skill performance by house officers and medical stu
dents. Performance of USC medical students, exposed to a uniform clini
cal breast evaluation curriculum, were compared with MSIVs from four o
ther medical schools, and postgraduate year I and II categorical surgi
cal residents. USC medical students were found to maintain performance
between an initial surgical OSCE breast station and a delayed clinica
l practice exam (CPX) reexam as MSIVs (breast exam, P = 0.21; patient-
physician interaction, P = 0.67). USC MSIVs had statistically signific
antly higher performance on the CPX breast station when compared with
other MSIVs (T = 11.701, two-tailed test, P = 0.0001). House officers
demonstrated significantly poorer skills than medical students (P = 0.
03). An incoming housestaff group showed improvement with clinical bre
ast evaluation checklists and orientation as part of their intern orie
ntation program and ongoing curriculum.
