目的：我们在2项研究中评估了VR腹腔镜模拟培训的ToT有效性。在第二项研究中，我们还评估了毒性接触率。ToT是等效组之间可检测到的性能改善，TER是执行相同任务的2个匹配组之间观察到的百分比性能差异，但其中一组在VR模拟上进行了预训练。设计：前瞻性，随机，盲法。参与者：在研究1中，经验丰富的腹腔镜外科医生（n = 195）和在研究2中腹腔镜新手（n = 30）被随机分为两组，一组在完成等效的真实世界任务之前接受VR模拟训练，另一组仅完成真实的世界任务。经验丰富的腹腔镜外科医生和在模拟器上接受培训的新手的表现明显优于对照组，从而证明了ToT。他们的表现显示，从虚拟到真实的任务的TER在7%到42%之间。在两项研究中，模拟培训对手术错误减少的影响最大（32- 42%）。VR与现实任务表现之间的相关性为r > 0.96（研究2）。结论：VR模拟训练为训练安全技能提供了一个强大而有效的平台。
Objectives: We assessed the effectiveness of ToT from VR laparoscopic simulation training in 2 studies. In a second study, we also assessed the TER. ToT is a detectable performance improvement between equivalent groups, and TER is the observed percentage performance differences between 2 matched groups carrying out the same task but with 1 group pretrained on VR simulation. Concordance between simulated and in-vivo procedure performance was also assessed.Design: Prospective, randomized, and blinded.Participants: In Study 1, experienced laparoscopic surgeons (n = 195) and in Study 2 laparoscopic novices (n = 30) were randomized to either train on VR simulation before completing an equivalent real-world task or complete the real- world task only.Results: Experienced laparoscopic surgeons and novices who trained on the simulator performed significantly better than their controls, thus demonstrating ToT. Their performance showed a TER between 7% and 42% from the virtual to the real tasks. Simulation training impacted most on procedural error reduction in both studies (32- 42%). The correlation observed between the VR and real-world task performance was r > 0.96 (Study 2).Conclusions: VR simulation training offers a powerful and effective platform for training safer skills.
