Examining differences in trends in the orthopedic surgery match for osteopathic and allopathic medical graduates after the transition to single accreditation

Abstract

Abstract Context The landscape of medical education in the United States has undergone significant changes, particularly with the rise of osteopathic medical students, constituting a substantial portion of medical school entrants. The merger of the Accreditation Council for Graduate Medical Education (ACGME) and the American Osteopathic Association (AOA) in 2020 opened residency slots to allopathic graduates that were previously historically allocated to osteopathic (Doctor of Osteopathic Medicine [DO]) physicians. This has impacted various medical specialties, notably orthopedic surgery. Despite an increase in orthopedic surgery applicants, the match rates for DO candidates have faced challenges, raising concerns about the impact of this merger on the future of orthopedic training for DO students. Objectives This research aims to analyze the trends in orthopedic surgery match rates for DO vs MD applicants since the single accreditation merger, which began in 2015 with a 5-year transition period that was finalized by 2020. By examining factors such as application numbers, research output, standardized test scores, and program director preferences, the study seeks to identify disparities and challenges faced by DO applicants in securing orthopedic surgery residencies. Methods This study utilized publicly available data from the National Residency Match Program (NRMP) 2018, 2020, and 2022 reports. Data encompassed applicant characteristics, including standardized test scores, research experiences, and match outcomes. The study also incorporated insights from NRMP program director surveys, focusing on interview and ranking practices. The analysis involved comparisons of application numbers, match rates, research productivity, and test scores between DO and MD applicants. Statistical analysis was employed to identify any statistically significant differences among the examined variables for the 3 years included in the study. Results The research revealed a consistent increase in orthopedic surgery applicants from both DO and MD backgrounds. However, MD applicants consistently had higher match rates compared to their DO counterparts, with the gap narrowing over the years. Notably, disparities persisted in research output, with MD applicants demonstrating a significant advantage in publications and presentations. Standardized test scores, although slightly higher for MD applicants, did not significantly impact the differences in match rates. MD applicants had statistically significantly higher numbers of applicants (P = .0010), number of publications (P = .0091), and number of research experiences (P = .0216) over the years examined. However, there was no statistically significant difference in the scores on Step 1 (P = .5038) or Step 2 (P = .4714) between MD and DO candidates. Conclusions Despite progress in the acceptance and ranking of DO applicants by program directors, the study highlights enduring challenges in orthopedic surgery match rates between DO and MD candidates. The lack of research opportunities for DO students stands out as a crucial area for improvement, necessitating systemic changes within medical education. Addressing this disparity and ensuring equal access to research experiences could mitigate the gap in match rates, promoting a more equitable environment for all aspiring orthopedic surgeons, regardless of their medical background. Such efforts are vital to fostering inclusivity and enhancing opportunities for osteopathic medical students pursuing competitive specialties like orthopedic surgery.
