Background/ObjectiveEducation is at the core of neurosurgical residency, but little research in to the cost of neurosurgical education exists. This study aimed to quantify costs of resident education in an academic neurosurgery program using traditional teaching methods and the Surgical Autonomy Program (SAP), a structured training program.MethodsSAP assesses autonomy by categorizing cases into zones of proximal development (opening, exposure, key section, and closing). All first-time, 1-level to 4-level anterior cervical discectomy and fusion (ACDF) cases between March 2014 and March 2022 from 1 attending surgeon were divided into 3 groups: independent cases, cases with traditional resident teaching, and cases with SAP teaching. Surgical times for all cases were collected and compared within levels of surgery between groups.ResultsThe study found 2140 ACDF cases, with 1758 independent, 223 with traditional teaching, and 159 with SAP. For 1-level to 4-level ACDFs, teaching took longer than it did with independent cases, with SAP teaching adding additional time. A 1-level ACDF performed with a resident (100.1 ± 24.3 minutes) took about as long as a 3-level ACDF performed independently (97.1 ± 8.9 minutes). The average time for 2-level cases was 72.0 ± 18.2 minutes independently, 121.7 ± 33.7 minutes traditional, and 143.4 ± 34.9 minutes SAP, with significant differences among all groups.ConclusionsTeaching takes significant time compared with operating independently. There is also a financial cost to educating residents, because operating room time is expensive. Because attending neurosurgeons lose time to perform more surgeries when teaching residents, there is a need to acknowledge surgeons who devote time to training the next generation of neurosurgeons.Copyright © 2023 Elsevier Inc.
