背景：我们的目的是确定观察手术或基于互联网的视频评论是否能预测外科办事员的表现。方法：回顾性回顾学生使用手术录像、观察手术、评估和考试成绩，构建探索性主成分分析。运用多元回归分析方法确定影响员工绩效的因素。结果：231名学生的病例记录数据显示，中位数为25例观察病例。学生访问网络视频平台的中位数为15次。主成分分析得出4个因子对变异的贡献率为74%，Kaiser-Meyer-Olkin系数为0.83。多变量回归预测货架评分（P < 0.0001）、内部临床技能考试分数（P < 0.0001）、主观评价（P < .001）和视频网站利用率（P < .001），但未观察到病例与整体表现显著相关。结论：在外科见习期间使用基于网络的手术视频平台与提高临床推理、知识储备和整体评估是独立相关的。因此，这种模式可以作为一个有用的辅助现场观察。(C) 2016 Elsevier Inc.版权所有。
BACKGROUND: We aim to determine whether observed operations or internet-based video review predict improved performance in the surgery clerkship.METHODS: A retrospective review of students' usage of surgical videos, observed operations, evaluations, and examination scores were used to construct an exploratory principal component analysis. Multivariate regression was used to determine factors predictive of clerkship performance.RESULTS: Case log data for 231 students revealed a median of 25 observed cases. Students accessed the web-based video platform a median of 15 times. Principal component analysis yielded 4 factors contributing 74% of the variability with a Kaiser-Meyer-Olkin coefficient of .83. Multivariate regression predicted shelf score (P < .0001), internal clinical skills examination score (P < .0001), subjective evaluations (P < .001), and video website utilization (P < .001) but not observed cases to be significantly associated with overall performance.CONCLUSIONS: Utilization of a web-based operative video platform during a surgical clerkship is an independently associated with improved clinical reasoning, fund of knowledge, and overall evaluation. Thus, this modality can serve as a useful adjunct to live observation. (C) 2016 Elsevier Inc. All rights reserved.
