Laparoscopic box simulation training is widely recognized as an assessment tool to facilitate psychomotor skills especially for novice surgeons. However, current commercialized training modules including pegs, gauze, clips, pins etc. are generally costly and relatively inaccessible. We introduce a simple and pioneer surgical training drill, the Origami Box Folding Exercise (OBFE), based on the validated evaluating system of objective structured assessment of technical skills (OSATS) constructed with the scoring system of procedure-specific checklist (PSC) and global rating scale (GRS).
Face and content validation of the OBFE and OSATS are evaluated by five endoscopic experts from two medical centers in Taiwan. This is a prospective observational study analyzing the pre-test/post-test result of OBFE from 37 participants in two individual workshops as training and evaluating method for laparoscopic psychomotor skills. Both the pre and post tests are video recorded with a time limit of 5 min graded by two independent evaluators based on the OSATS scoring system.
The reliability of PSC, GRS, and intergroup value between PSC and GRS were 0.923, 0.926 and 0.933, respectively. Inter-rater reliability of PSC, GRS, and both were 0.985, 0.932 and 0.977, respectively. Construct validity of PSC and GRS were statistically significant, with p-value 0.006 and 0.001, respectively.
OBFE enhances laparoscopic psychomotor skills with requirement of a single piece of paper. The associated OSATS tool for a 5-min OBFE test was validated. OBFE training is an efficient training and assessment system to promote psychomotor skills in laparoscopic box simulation drill which requires simple and economical preparation.
腹腔镜箱模拟训练被广泛认为是一种促进心理运动技能的评估工具，尤其适用于新手外科医生。然而，目前商业化的培训模块包括钉子、纱布、夹子、别针等，通常价格昂贵且相对难以获得。我们引入了一种简单而具有开创性的手术训练训练方法，折纸箱折叠训练（OBFE），它基于经过验证的客观结构化评估技术技能（OSATS）评估系统，该系统采用程序特定检查表（PSC）和整体评估量表（GRS）的评分系统。
OBFE 和 OSATS 的表面效度和内容效度由来自台湾两家医疗机构的五名内镜专家进行评估。这是一项前瞻性观察研究，分析了来自两个单独工作坊的 37 名参与者的 OBFE 预测试/后测试结果，作为腹腔镜心理运动技能的培训和评估方法。预测试和后测试都使用时间限制为 5 分钟的视频记录，并由两名独立评估者根据 OSATS 评分系统进行评分。
PSC、GRS 和 PSC 与 GRS 之间的组间值的可靠性分别为 0.923、0.926 和 0.933。PSC、GRS 和两者的组内可靠性分别为 0.985、0.932 和 0.977。PSC 和 GRS 的结构有效性具有统计学意义，p 值分别为 0.006 和 0.001。
OBFE 增强了使用单张纸的腹腔镜心理运动技能。相关的 5 分钟 OBFE 测试的 OSATS 工具经过验证。OBFE 培训是一种在腹腔镜箱模拟训练中促进心理运动技能的有效培训和评估系统，它需要简单和经济的准备。
