Dermatology Curriculum for Internal Medicine Residents: A Randomized Trial

Abstract

BACKGROUND: Physicians in specialties other than dermatology care for the majority of patients with skin diseases, yet most physicians receive little training in dermatology. OBJECTIVES: The primary objective of this study was to determine whether there would be a sizable (20%) improvement in posttraining scores for internal medicine residents after completing 1 of 3 assigned curricula. A secondary objective was to determine whether there were significant differences in improvement among the 3 resident cohorts after completing their curriculum. Finally, we explored the residents' change in perceived clinical knowledge postcurriculum. METHODS: Thirty-six postgraduate year 2 internal medicine residents were randomized to complete 1 of 3 one-month dermatology curricula (didactic, clinical, or combined). The main outcome measure was performance on different sets of Medical Knowledge Self-Assessment Program (MKSAP)-15 questions at study entry and completion. A secondary outcome was self-rated performance in 3 clinical domains. RESULTS: All participants completed the study. All curricula led to an improvement in MKSAP-15 scores, but only students who completed the didactic curriculum demonstrated a 20% improvement in posttraining scores. A larger number of residents completing the clinical and didactic curricula rated their clinical performance as improved compared to those who completed the combined curriculum. CONCLUSIONS: While all 3 curricula led to improvement, as measured by a standardized assessment, a didactic curriculum in dermatology resulted in the largest improvement in knowledge as measured by a multiple-choice test.
