Despite these developments, the regulations governing neurosurgical training and evaluation methods for training hospitals have remained largely unchanged, necessitating comprehensive revisions in response to evolving medical environments. To provide balanced participation opportunities for neurosurgery residents, the Korean Neurosurgical Society formed the Training Status Investigation Standard Change Task Force (TF team) under the Training Education Committee. This paper presents the TF team's findings and proposals for revising training status investigation standards and evaluation criteria. Through the processes including a lot of team meetings, workshops, education programs, official communications with 12 division societies, benchmarking from other societies and analysis of encrypted data from the past 5 years for neurosurgical training hospitals, the TF team created a revised training status investigation proposal, supplemented main surgery criteria. And we applied this revised proposal to the training status investigation data collected from training hospitals in 2022 for simulation. We reduced the score for main surgeries to 10 points, introduced core competency surgery standards, allocating 5 points each for brain core competency surgery and spine and peripheral core competency surgery, for a total of 10 points. We also adjusted the major surgery score to 13 points, expanding the total surgery index score to 33 points. We introduced additional definitions for main surgeries in the areas of spine, pediatrics, and functional surgery. The equipment score was reduced from 17 to 9 points. We specified minimum requirements for resident allocation eligibility, and if a hospital meets all of these criteria, they become eligible to apply for resident allocation. We introduced a new bonus point system for hospitals performing mechanical thrombectomy or stenting and surgery for peripheral nerve diseases. The proposed revisions aim to improve the training and education of neurosurgical residents and overall neurosurgical care in Korea by creating a balanced and differentiated evaluation system for training hospitals.
