Assessing clinical competence of medical students in women’s health care: use of the objective structured clinical examination

Abstract

Objective: To assess clinical competency of third-year medical students completing a problem-oriented, primary care emphasis clerkship in obstetrics and gynecology using an objective structured clinical examination, and to determine the feasibility of implementing the objective structured clinical examination in the curriculum. Methods: Sixteen groups of third-year medical students were evaluated prospectively on their exit performances with a six-station objective structured clinical examination designed to test clinical competency in basic primary care obstetrics-gynecology. Consistency of scores across stations, differences in performance for separate groups, and relationship of objective structured clinical examination scores compared with other indicators of medical proficiency, such as written examinations and faculty evaluations, were assessed. Results: One hundred ninety-eight students were evaluated over 25 months. Test reliability across stations revealed α values ranging between .50 and .56. Correlations between performance on the objective structured clinical examination and the written test ( r = .10) were low, demonstrating that the objective structured clinical examination clearly tests a separate domain of student capability. Cost of the objective structured clinical examination was $81.66 per student. Conclusion: The objective structured clinical examination is a reliable and valid test of the clinical competence of medical students in the primary health care of women. It provides information that is not obtained by more traditional assessment modalities at a reasonable cost.
