我们提出了一种独特的基于模拟器的方法，用于评估外科学员的技术和非技术（认知）技能，同时沉浸在一个完整的医疗模拟环境中。此外，我们还纳入了两个危机情景，以评估认知策略选择对低水平手术技能的影响。因此，可以在我们的平台上评估这些混合模式场景的培训，从而改进评估并为认证奠定更坚实的基础，并有可能减少手术室中不良事件的发生。与19名初级外科医生一起对我们的工作进行科学评估和验证，以实现以下目标：1）提供可用性的定性测量，2）评估外科医生的椎体成形术技术性能，3）探索危机期间精神负荷与手术性能之间的关系。我们的研究结果表明：1）外科医生对我们建模的模拟环境的表面有效性评分非常高（4.68 ±0.48，使用5分制Likert量表），2）外科医生培训能够更快地完成任务，3）危机情景的引入对外科医生的客观表现产生了负面影响。综上所述，我们的研究结果强调需要开发逼真的模拟环境，年轻的居民准备在手术室应对紧急事件。
We present a unique simulator-based methodology for assessing both technical and nontechnical (cognitive) skills for surgical trainees while immersed in a complete medical simulation environment. Further, we have included two crisis scenarios which allow for the evaluation of the effect of cognitive strategy selection on the low-level surgical skills. Training these mixed-mode scenarios can thereby be evaluated on our platform, allowing for improved assessment and a stronger foundation for credentialing, with the potential to reduce the occurrence of adverse events in the operating room. Scientific evaluation and validation of our work is conducted together with 19 junior surgeons in order to achieve the following goals: 1) to provide a qualitative measure of usability, 2) to assess vertebroplasty technical performance of the surgeon, and 3) to explore the relationship between mental workload and surgical performance during crisis. Our results indicate that: 1) the surgeons scored the face validity of our modeled simulation environment very highly ( 4.68 ±0.48, using a 5-point Likert scale), 2) surgeon training enabled completion of tasks more quickly, and 3) the introduction of crisis scenarios negatively affected the surgeons' objective performance. Taken together, our results underscore the need to develop realistic simulation environments that prepare young residents to respond to emergent events in the operating room.
