Neuroendovascular Fellowship Training: Self-Assessment of a Program Accredited by the Committee on Advanced Subspecialty Training.

The University at Buffalo's neuroendovascular fellowship is one of the longest running fellowship programs in North America. The burgeoning neurointerventional workforce and the rapid growth in the neurointerventional space on the heels of groundbreaking clinical trials prompted us to assess the fellowship's academic impact and its graduates' perceptions and productivity. An anonymized web-based survey was sent to all former neuroendovascular fellows with specific questions pertaining to current practice, research and funding, and perceptions about the fellowship's impact on their skills, competitiveness, and compensation. Additionally, the h-index was calculated to assess the academic productivity of each graduated fellow. Among 50 former fellows, 42 (84%) completed the survey. The fellows came from various countries, ethnic backgrounds, and specialties including neurosurgery (n = 39, 93%), neurology (n = 2, 5%), and neuroradiology (n = 1, 2%). Twenty (48%) respondents were currently chairs or directors of their practice. Most (n = 30, 71%) spent at least 10% of their time on research activities, with 27 (64%) receiving research funding. The median h-index of all 50 former fellows was 14. The biggest gains from the fellowship were reported to be improvement in endovascular skills (median = 10 on a scale of 0-10 [highest]) and increase in competitiveness for jobs in vascular neurosurgery (median = 10), followed by increase in academic productivity (median = 8), and knowledge of vascular disease (median = 8). In an era with open calls for moratoriums on endovascular fellowships, concerns over market saturation, and pleas to improve training, fellowship programs perhaps merit a more objective assessment. The effectiveness of a fellowship program may best be measured by the academic impact and leadership roles of former fellows.
