目的：经验证的高保真度模拟模型将为新手讲授胸腔镜EA/TEF修复术提供安全的环境。本研究的目的是评估有效性证据的性能指标EA/TEF simulator.Methods：IRB豁免数据收集自12个自我报告的“新手”和8个“经验丰富”的儿科外科医生。参与者使用调查评级评估EA/TEF修复模拟器，并对测试内容有效性证据进行分析。此外，由两位外科医生使用技术技能客观结构化评估（OSATS）工具对去识别手术性能进行录像和独立评级。新手和经验丰富的OSATS进行了比较，p <0.05显着。内部结构得到了高项目一致性（a = 0.95和0.96）和评级者间一致性（ICC）[0.52，0.84]的支持。经验丰富的外科医生在所有五个主要和两个补充OSATS项目（p <0.05）比新手在一个显着更高的水平进行。结论：有利的参与者评级表明模拟器是相关的临床实践和有价值的学习工具。此外，性能评级可以区分EA/TEF修复的经验和新手性能。这些发现支持使用模拟器进行性能评估，代表了预期用于儿科手术培训的模拟器的首次确认措施。(C)2014爱思唯尔公司All rights reserved.
Purpose: A validated high fidelity simulation model would provide a safe environment to teach thoracoscopic EA/TEF repair to novices. The study purpose was to evaluate validity evidence for performance measures on an EA/TEF simulator.Methods: IRB-exempt data were collected from 12 self-reported "novice" and 8 "experienced" pediatric surgeons. Participants evaluated the EA/TEF repair simulator using survey ratings that were analyzed for test content validity evidence. Additionally, deidentified operative performances were videotaped and independently rated by two surgeons using the Objective Structured Assessment for Technical Skills (OSATS) instrument. Novice and experienced OSATS were compared with p < .05 significant.Results: Participants had high overall simulator ratings. Internal structure was supported by high interitem consistency (a = .95 and .96) and interrater agreement (ICC) [.52, .84] for OSATS ratings. Experienced surgeons performed at a significantly higher level than novices for all five primary and two supplemental OSATS items (p < .05).Conclusion: Favorable participant ratings indicate the simulator is relevant to clinical practice and valuable as a learning tool. Further, performance ratings can discriminate experienced and novice performances of EA/TEF repair. These findings support the use of the simulator for performance assessment, representing the first validated measures from a simulator intended for pediatric surgical training. (C) 2014 Elsevier Inc.
