The role of limited access to students from more diverse nonfeeder medical schools in creating diversity inequities in neurosurgical residency

Abstract

OBJECTIVE Improving racial/ethnic diversity in neurosurgery is a long-standing issue that needs to be addressed. The positive correlation between medical students with home neurosurgery programs and successful matriculation into neurosurgical residency is well documented. In this article, the authors explored the relationship between decreased racial/ ethnic diversity in neurosurgery residency programs and racial/ethnic diversity in feeder medical schools. METHODS The authors conducted a standardized review of the literature to evaluate potential causes for decreased racial/ ethnic diversity within neurosurgery. Additionally, they calculated the average enrollment of Black/African American medical students at the top 5 neurosurgery feeder medical schools (determined by Antar et al. following the 2014–2020 match cycles) during the 2021–2022 school year and compared that with the enrollment at US allopathic medical schools with the highest enrollment of Black/African American students. They also compared these two groups in terms of how many students they sent into neurosurgery residency programs from 2014 to 2020. For each of these comparisons, the authors conducted a two-sample t-test to evaluate correlation between these two variables. RESULTS There was significantly lower average enrollment of Black/African American students at the top 5 feeder medical programs into neurosurgery residency (80.6 ± 8.32) compared with the top 5 medical schools with Black/African American enrollment in the 2021–2022 school year (279 ± 122.00, p < 0.05). The authors also found a significant increase in the number of students entering neurosurgery residency programs between the top 5 feeder medical programs into neurosurgery residency (30.8 ± 6.06) and the top 5 medical programs for Black/African American enrollment (6 ± 6.16, p < 0.0001). CONCLUSIONS In this paper, the authors examined, through a Black/African American lens, the role of racial/ethnic diversity in medical schools that historically send many students to neurosurgery residency. This study sought to provide insight into this problem and examine how Black/African American students from nonfeeder medical schools are disproportionately affected. The authors’ findings suggest that the lack of Black/African American representation in neurosurgery is strongly correlated with the diversity efforts of medical schools. Lastly, the authors highlight the University of Miami’s Summer Research Scholarship in Neurosurgery for Medical Students and other programs as potential solutions to combat the lack of racial/ethnic diversity in neurosurgery.
