Fundamental Curriculum Change with 1-Year Pre-Clerkship Phase and Effect on Stress Associated with Residency Specialty Selection

Vanderbilt University School of Medicine recently changed from 2 pre-clerkship years (Traditional curriculum) to a 1.5-year pre-clerkship phase for one class (Hybrid curriculum) to a 1-year pre-clerkship phase (Curriculum 2.0). This study investigated the relationship between shortened pre-clerkship training and stress associated with selecting a residency field. The surveyed graduating medical student population included one cohort from the Traditional and Hybrid curricula, and the first two cohorts from Curriculum 2.0. The authors modeled recollected stress levels using a Zero-Inflated Linear Mixed Model with additional covariate and random effects adjustments. Specialty decision-related stress levels increased in the Hybrid curriculum by 10.208 points [p = 0.0115, 95% CI 2.293, 18.122] on a 0–100 point scale. Curriculum 2.0 students had an insignificant increase in stress of 4.062 points [p = 0.304, 95% CI − 3.690, 11.814] relative to the Traditional curriculum. Time since starting medical school and time when a specialty was chosen were the largest factors associated with stress. While this study only evaluated a single facet of the potential downstream effects of curricular change, these data should inspire confidence for reform efforts as a significant increase in specialty decision-related stress present in Hybrid curriculum resolved in both cohorts of Curriculum 2.0.
