Subspecialty and Training Preferences for U.S. Neurosurgery Faculty with International Training.

BACKGROUND: Academic neurosurgeons with international medical training play a large role in the U.S. neurosurgical workforce. We aimed to compare U.S.-trained neurosurgeons with internationally trained neurosurgeons to reveal differences in subspecialty preferences and training opportunities abroad. METHODS: We identified 1671 neurosurgeons from 115 Accreditation Council for Graduate Medical Education (ACGME)-accredited neurosurgical residency programs. Data on demographics, institution characteristics, and chosen subspecialty were collected, and faculty were divided based on location of training. Univariate analysis and multivariable logistic regression compared faculty characteristics between training locations. RESULTS: Compared with the U.S. medical school + U.S. residency group, the international medical graduate + U.S. residency group was more likely to subspecialize in oncology/skull base and vascular neurosurgery and complete a fellowship in the United States or internationally (P < 0.05). The international medical graduate + international residency group was more likely to subspecialize in oncology/skull base neurosurgery, more likely to complete an international fellowship, and less likely to practice general neurosurgery (P < 0.05). Neurosurgeons in pediatrics, radiosurgery, and vascular subspecialties were more likely to receive fellowship training in any location (P < 0.05). Additionally, functional neurosurgeons were more likely to complete fellowships internationally, spinal neurosurgeons were less likely to pursue international fellowships, and peripheral nerve neurosurgeons were more likely to have dual fellowship training in both the United States and abroad (P < 0.05). CONCLUSIONS: International medical training affected subspecialty choice and fellowship training. Internationally trained neurosurgeons more often specialized in oncology and vascular neurosurgery. Functional neurosurgeons were more likely to complete international fellowships, spine neurosurgeons were less likely to complete international fellowships, and peripheral nerve neurosurgeons more often had both U.S. and international fellowships.

Academic Productivity of United States Neurosurgeons Trained Abroad.

BACKGROUND: Previous research in neurosurgery has examined academic productivity for U.S. medical graduates and residents. However, associations between scholarly output and international medical education, residency training, and fellowship training are scarcely documented. METHODS: We identified 1671 U.S. academic neurosurgeons in 2020 using publicly available data along with their countries of medical school, residency, and fellowship training. Using Scopus, h-index, number of publications, and number of times publications were cited were compiled. Demographic, subspeciality, and academic productivity variables were compared between training locations using univariate analysis and multivariable linear regression. RESULTS: Of the current neurosurgery faculty workforce, 16% completed at least 1 component of their training abroad. Canada was the most represented international country in the cohort. Academic productivity for neurosurgeons with international medical school and/or international residency did not significantly differ from that of neurosurgeons trained in the United States. Neurosurgeons with ≥1 U.S. fellowships or ≥1 international fellowships did not have higher academic productivity than neurosurgeons without a fellowship. However, dual fellowship training in both domestic and international programs was associated with higher mean h-index (ß = 6.00, 95% confidence interval 1.01 to 10.98, P = 0.02), higher citations (ß = 2092.0, 95% confidence interval 460.1 to 3724.0, P = 0.01), and a trend toward higher publications (ß = 36.82, 95% confidence interval -0.21 to 73.85, P = 0.051). CONCLUSIONS: Neurosurgeon scholarly output was not significantly affected by international training in medical school or residency. Dual fellowship training in both a domestic and an international program was associated with higher academic productivity.
