Neurosurgical Skills Assessment: Measuring Technical Proficiency in Neurosurgery Residents Through Intraoperative Video Evaluations

摘要: Objectives Although technical skills are fundamental in neurosurgery, there is little agreement on how to describe, measure, or compare among surgeons. The primary goal of this study was develop a quantitative grading scale for surgical performance that distinguishes operator skill when graded by domain experts (residents, attendings, and nonsurgeons). Scores provided raters should be highly reliable with respect scores from other observers. Methods Neurosurgery residents were fitted head-mounted video camera while performing craniotomies under attending supervision. Seven videos, 1 each postgraduate year (PGY) level (1–7), anonymized scored 16 8 residents, 7 nonsurgeons using scale. graded: incision, efficiency instrument use, cauterization, tissue handling, drilling/craniotomy, confidence, training level. Results A strong correlation found between score PGY ( P t test). Significant variation junior observed, senior residents' not significantly different one another. Interrater reliability, measured against observers, high r  = 0.581 ± 0.245, Spearman), as assessment resident 0.583 0.278, Spearman). Both variables strongly correlated 0.90, Pearson). Attendings, did differently 0.46, analysis variance). Conclusions Technical neurosurgery recorded during craniotomy can interrater reliability. Surgeons alike readily distinguish levels. This type could used coach track over time, potentially Developing an objective tool evaluate would useful several areas education.
