Accurate assessment is imperative for learning, feedback and progression. The aim of this study was to examine whether surgeons can accurately self-assess their technical and nontechnical skills compared with expert faculty members' assessments.
Twenty-five surgeons performed a laparoscopic cholecystectomy (LC) in a simulated operating room. Technical and nontechnical performance was assessed by participants and faculty members using the validated Objective Structured Assessment of Technical Skills (OSATS) and the Non-Technical Skills for Surgeons scale (NOTSS).
Assessment of technical performance correlated between self and faculty members' ratings for experienced (median score, 30.0 vs 31.0; ρ = .831; P = .001) and inexperienced (median score, 22.0 vs 28.0; ρ = .761; P = .003) surgeons. Assessment of nontechnical skills between self and faculty members did not correlate for experienced surgeons (median score, 8.0 vs 10.5; ρ = -.375; P = .229) or their more inexperienced counterparts (median score, 9.0 vs 7.0; ρ = -.018; P = .953).
Surgeons can accurately self-assess their technical skills in virtual reality LC. Conversely, formal assessment with faculty members' input is required for nontechnical skills, for which surgeons lack insight into their behaviours.
准确的评估对于学习、反馈和进步至关重要。本研究旨在检验外科医生是否能够准确地自我评估其技术和非技术技能，与专家教员的评估相比。
25 名外科医生在模拟手术室中进行腹腔镜胆囊切除术（LC）。参与者和教员使用经过验证的客观结构化评估技术技能（OSATS）和外科医生非技术技能量表（NOTSS）评估技术和非技术表现。
经验丰富（中位数评分，30.0 与 31.0；ρ =.831；P =.001）和经验不足（中位数评分，22.0 与 28.0；ρ =.761；P =.003）外科医生的自我评估和教员评估的技术表现评估之间存在相关性。自我评估和教员评估的非技术技能之间没有相关性，无论是对于经验丰富的外科医生（中位数评分，8.0 与 10.5；ρ = -.375；P =.229）还是经验不足的外科医生（中位数评分，9.0 与 7.0；ρ = -.018；P =.953）。
外科医生可以准确地自我评估虚拟现实 LC 中的技术技能。相反，对于非技术技能，需要有教员的正式评估，因为外科医生缺乏对自己行为的洞察力。
