Surgical clerkship or medical clerkship first: Does it make a difference?

Abstract

Introduction: This study compares NBME surgical clerkship scores of students who completed their medicine clerkship before their surgical clerkship with the performance of those who had not previously completed their medical clerkship.

Methods: The study included 815 New York University School of Medicine students from the years 2014-2018 (571 students took medicine first, while 244 took surgery first). Performance on the surgical clerkship was assessed using the NBME SHELF examination. Statistical comparisons were performed via 2-tailed, independent-samples, unequal-variance t-tests.

Results: Mean NBME surgical SHELF scores of the students who had previously taken medicine were significantly higher than students who had not (mean 78.6 vs. 73.5, p < 0.001). Students who had solely medicine (as their first clerkship) before surgery also performed significantly better (mean 78.8 vs. 73.5, p < 0.001). Students who completed surgery later in the year did not perform better on the surgical SHELF, so long as both surgical clerkship cohorts had completed medicine.

Conclusion: Students who completed their core medical clerkship prior to their surgical clerkship scored significantly better on the NBME surgical SHELF examination.
