RESUMEN
Background: Medical school clerkship grades are used to evaluate orthopedic surgery residency applicants, however, high interinstitutional variability in grade distribution calls into question the utility of clerkship grades when evaluating applicants from different medical schools. This study aims to evaluate the variability in grade distribution among medical schools and look for trends in grade distribution over recent years. Methods: Applications submitted to Rush University's orthopedic surgery residency program from 2015, 2019, and 2022 were collected from the Electronic Residency Application Service. Applications from the top 100 schools according to the 2023-2024 U.S. News and World Report Research Rankings were reviewed. The percentage of "honors" grades awarded by medical schools for the surgery and internal medicine clerkships were extracted from applicants' Medical Student Performance Evaluation letters. Results: The median percentage of honors given in 2022 was 36.0 % (range 10.0-82.0) for the surgery clerkship and 33.0 % (range 6.7-80.0) for the internal medicine clerkship. Honors were given 6.6 % more in the surgery clerkship in 2022 compared to 2015. There was a negative correlation between a higher (worse) U.S. News and World Report research ranking and the percentage of honors awarded in 2022 for the surgery and internal medicine clerkships. Conclusion: There is substantial interinstitutional variability in the rate that medical schools award an "honors" grade with evidence of grade inflation in the surgery clerkship. Residency programs using clerkship grades to compare applicants should do so cautiously provided the variability demonstrated in this study.
