Simulation based training with training models is being increasingly used as a tool to help trainees mount the learning curve. However, validation studies of surgical simulators are often limited by small numbers. We aim to evaluate the feasibility of validating simulation-training tasks in laparoscopy and flexible ureteroscopy (FURS) rapidly at a large-scale conference setting for residents.
Seventy-six urology residents from various Asian countries were assessed on their laparoscopic and FURS skills during the 14th Urological Association of Asia Congress 2016. Residents performed the peg transfer task from the fundamentals of laparoscopic surgery (FLS) and completed inspection of calyces and stone retrieval using a flexible ureteroscope in an endourological model. Each participant's experience (no experience, 1-30 or >30 procedures) in laparoscopy, rigid ureteroscopy (RURS) and FURS was self-reported.
Median time taken to complete the laparoscopic task decreased with increasing laparoscopic experience (209 s 177 s 145 s, =0.008) whereas median time taken to complete the FURS tasks reduced with increasing FURS experience (405 s 250 s 163 s, =0.003) but not with RURS experience (400.5 s 397 s 331 s, =0.143), demonstrating construct validity. Positive educational impact of both tasks was high, with mean ratings of 4.16/5 and 4.10/5 respectively, demonstrating face validity.
Our study demonstrates construct and face validities of laparoscopy and FURS simulation tasks among residents at a conference setting. Validation studies at a conference setting can be an effective avenue for evaluating simulation models and curriculum in the future.
使用训练模型进行基于模拟的培训正越来越多地被用作帮助学员跨越学习曲线的一种工具。然而，手术模拟器的验证研究往往因数量较少而受到限制。我们旨在评估在大型会议环境中针对住院医师快速验证腹腔镜手术和软性输尿管镜检查（FURS）模拟训练任务的可行性。
在2016年第14届亚洲泌尿外科协会大会期间，对来自亚洲各国的76名泌尿外科住院医师的腹腔镜手术和FURS技能进行了评估。住院医师在腹腔镜手术基础（FLS）中执行了移钉任务，并在腔内泌尿外科模型中使用软性输尿管镜完成了肾盏检查和结石取出。每位参与者在腹腔镜手术、硬性输尿管镜检查（RURS）和FURS方面的经验（无经验、1 - 30次或>30次手术）均为自我报告。
完成腹腔镜任务的中位时间随着腹腔镜经验的增加而减少（209秒 177秒 145秒，P = 0.008），而完成FURS任务的中位时间随着FURS经验的增加而减少（405秒 250秒 163秒，P = 0.003），但与RURS经验无关（400.5秒 397秒 331秒，P = 0.143），证明了结构效度。两项任务的积极教育影响都很高，平均评分分别为4.16/5和4.10/5，证明了表面效度。
我们的研究证明了在会议环境中住院医师腹腔镜手术和FURS模拟任务的结构效度和表面效度。在会议环境中进行验证研究可能是未来评估模拟模型和课程的有效途径。
