To assess for usefulness and validity evidence for incorporating the C-Arm Trainer (CAT) simulator into the annual AUA hands on course for training percutaneous nephrolithotomy (PCNL).
The course started with a didactic session followed by four stations for training the "bull's eye" technique using the CAT simulator. Each station included a pre-test, 30-min practice on the simulator, and post-test. All participants were assessed using a 4-item checklist. All participants were asked to fill in a qualitative self-assessment questionnaire after the pre- and the post-test, and respond to a course evaluation questionnaire and post-course survey.
A total of 38 physicians, who attended the hands on course, voluntarily participated in the study. Only 21.1% had previous practice on PCNL simulators. Compared with the results of the checklist total score and the qualitative self-assessment questionnaire scores after the pre-test, there was significant improvement in the checklist total score (p < 0.001), temporal demands (p = 0.003), situational stress (p = 0.003, and performance (0.003) after the post-test. A total of 14 (36%) participants responded to the course evaluation questionnaire, 50% evaluated the course as excellent, 28.6% as very good, and 21.4% as good. Unfortunately, only five (13%) participants responded to the post-course survey, 4/5 implemented the new competencies and knowledge into their practice, and 3/5 have attempted to obtain fluoroscopic guided PCA without assistance.
The CAT simulator was considered useful for training the percutaneous renal access procedure. There was significant improvement in the qualitative and quantitative assessment parameters after the post-test compared with the pre-test.
评估将 C 臂训练器(CAT)模拟器纳入年度 AUA 实践课程中用于培训经皮肾镜取石术(PCNL)的效用和有效性证据。
课程开始时进行了一次讲座,然后在四个站点使用 CAT 模拟器进行“靶心”技术培训。每个站点都包括预测试、在模拟器上练习 30 分钟,以及后测试。所有参与者都使用 4 项检查表进行评估。所有参与者在预测试和后测试后都填写了一份定性自我评估问卷,并对课程评估问卷和课后调查进行了回复。
共有 38 名参加实践课程的医生自愿参加了这项研究。只有 21.1%的人之前有过 PCNL 模拟器的实践经验。与预测试后的检查表总分和定性自我评估问卷评分相比,检查表总分(p<0.001)、时间需求(p=0.003)、情境压力(p=0.003)和操作表现(p=0.003)都有显著提高。共有 14 名(36%)参与者回复了课程评估问卷,50%的人认为课程非常出色,28.6%的人认为课程很好,21.4%的人认为课程不错。不幸的是,只有五名(13%)参与者回复了课后调查,4/5 名参与者将新的能力和知识应用到了实践中,3/5 名参与者尝试在没有帮助的情况下进行荧光镜引导 PCA。
CAT 模拟器被认为是培训经皮肾穿刺入路程序的有用工具。与预测试相比,后测试的定性和定量评估参数有显著提高。
