Mapping the landscape of pediatric neurosurgery: geography, gender, and trends over time

OBJECTIVE Recently there has been an increase in pediatric neurosurgical fellowship graduates. It is important to understand the current pediatric neurosurgical workforce to help with prospective strategic workforce planning. The authors sought to determine 1) the geographic distribution and regional retention after training and 2) academic and leadership metrics by geographic location, era of training, and gender for practicing pediatric neurosurgeons in the United States. METHODS Current practicing pediatric neurosurgeons were identified through American Board of Pediatric Neurological Surgery (ABPNS) certification status and the American Association of Neurological Surgeons directory. NIH RePORTER, Web of Science, and departmental and hospital networking websites were used to collect data on demographics, training, leadership, NIH involvement, and academic metrics. RESULTS A total of 298 ABPNS-certified pediatric neurosurgeons were identified as currently practicing in the United States. Of these pediatric neurosurgeons, 26.2% were women, 74.5% were academic, and 11.7% have received current or past NIH funding. There were significant differences in the concentration of pediatric neurosurgeons per general population based on region. A total of 117 (39.3%) pediatric neurosurgeons held leadership positions; 4 (1.3%) served as neurosurgery department chairs, 67 (22.5%) served as chief of pediatric neurosurgery (9 of whom were women), 12 (4.0%) served as residency program directors, and 32 (10.7%) served as pediatric fellowship directors. Women were more likely to currently practice in the same region in which they trained for medical school (p = 0.050), have a lower academic rank (p = 0.004), and have a lower h-index (p < 0.001). Pediatric neurosurgeons practicing in the Northeast were more likely to have completed residency (p = 0.022) and medical school (p = 0.002) in the same region as their current practice. CONCLUSIONS There are differences in the concentration of pediatric neurosurgeons based on region. In pediatric neurosurgery, women hold fewer leadership positions, have lower academic ranks, and are less academically impactful as measured by the h-index. As the demand for pediatric neurosurgeons evolves, thoughtful monitoring of the distribution and composition of the neurosurgical workforce can help ensure equitable access to care across the country.
