ObjectiveStereotactic radiosurgery (SRS) represents an expanding approach for neurosurgeons and radiation oncologists. We evaluate educational gaps of senior residents drawn from each specialty as part of a focused SRS course. We also evaluate the strengths and limitations of SRS training in current residency programs of the course residents and faculty.MethodsThe American Association of Neurological Surgeons and American Society of Radiation Oncology jointly held a senior resident course in SRS. Residents were nominated by program directors from across the United States. Thirty residents were chosen to participate in the course. The residents were surveyed before and after the course. Faculty (n = 14) were also surveyed to ascertain their perspectives on current training in SRS.ResultsMost (96.7%) of the residents planned to perform SRS when finished, and 94% anticipated SRS indications to expand. Regarding SRS technique, 47% reported average/above average understanding of intracranial SRS; only 17% expressed similar understanding of spinal SRS. Before the course, 76.6% noted below average/average ability to recognize and manage SRS complications. Twenty-three percent of the faculty indicated that graduating residents from their programs were unprepared to perform radiosurgery. Residents' self-assessed understanding of brain SRS indication (P = 0.000693), SRS techniques (P = 0.000021), spinal SRS indications (P = 0.000050), spinal SRS techniques (P = 0.000019), and complication recognition and management (P = 0.00033) significantly improved following the course.ConclusionsKnowledge and training gaps in SRS appear evident to the senior residents and faculty of both specialties. We believe that other educational opportunities for SRS experience are necessary to optimize clinical competency, as well as meet future clinical staffing needs for this expanding, multidisciplinary approach. Further evaluation of gaps in SRS is necessary through a larger, nationwide survey of U.S. neurosurgeons, program directors, and residents.Copyright © 2017 Elsevier Inc. All rights reserved.
