OBJECTIVE: Our Institution instituted curriculum reform in 2013. We sought to examine the impact of rotation order on the end of clerkship National Board of Medical Examiners (NBME) Obstetrics and Gynecology (Ob/Gyn) Subject Exam scores after curriculum restructuring. DESIGN: This is a retrospective analysis of Ob/Gyn NBME scores over 2 years after curriculum reform. At our university, a 15-week block is divided into 5-week intervals of General Surgery, Ob/Gyn, and surgical subspecialties, in any order. During the 16 weeks, students take the NBME Subject Examinations for Ob/Gyn and Surgery. We defined rotation groups by proximity to the shelf exam. Group 1 completed Ob/Gyn first, furthest away from the exam, Group 2 completed Ob/Gyn second, and Group 3 completed Ob/Gyn last, closest to the test. We compared average shelf exam scores between Groups. SETTING: Uniformed Services University of Health Sciences during the clerkship year. PARTICIPANTS: Medical students at the Uniformed Services University. RESULTS: We obtained data from 331 students (118 students in Group 1, 106 in Group 2, and 107 in Group 3). Scores ranged from 55 to 99 (mean 72.5, SD 7.3). Mean (SD) NBME score was 71.9 (6.9) in Group 1, 73.2 (7.2) in Group 2, and 72.6 (7.7) in Group 3 (p = 0.415). CONCLUSION: Rotation order does not affect NBME Ob/Gyn Subject exam scores in a fifteen-week integrated clerkship block.
