Educational opportunities with simulation are now available to teach endoscopic skills outside the clinical setting. The goal of this study is to assess the learning curve and subjective impressions of cystoscopic tasks performed by untrained subjects on a computer-based simulator using a standardized curriculum.
We evaluated ten novice subjects on a computer-based cystoscopic simulator (URO Mentor, Simbionix, Lod, Israel) during a standardized cystoscopy skills course developed for the study. All trainees performed three basic cystoscopic tasks as part of the curriculum. Subjects were evaluated until a steady state of performance was observed. Subjectively, participants assessed their performance and opinions regarding the computer-based simulator.
Among the ten novice subjects (five men, five women), a median of six training sessions were required to achieve a steady state of performance. Significant performance improvements were noted with additional simulator time (P<0.001), however, the rate of improvement declined with time. Regression analysis of completion times revealed significant gender effects for one cystoscopic task. At study end, gender performance differences for any task were not significant. Uniformly, novices felt that URO Mentor was easy to use and provided an overall realistic training experience.
In this study a computer-based simulator was successfully incorporated into a training curriculum for cystoscopy education. For simulated tasks performed with rigid and flexible cystoscopes, a median of six training sessions was necessary. Objectively, performance on the testing scenarios significantly increased with experience. Subjectively based on nonvalidated criteria, comfort level, and perceived competency increased significantly from the pre- to postcourse evaluations.
现在可以利用模拟技术提供教育机会,在临床环境之外教授内镜技能。本研究的目的是评估未经培训的受试者使用标准化课程在基于计算机的模拟器上执行膀胱镜检查任务的学习曲线和主观印象。
在为该研究开发的标准化膀胱镜检查技能课程中,我们在基于计算机的膀胱镜模拟器(URO Mentor,Simbionix,以色列罗德)上评估了10名新手受试者。所有受训者都执行了三项基本膀胱镜检查任务,作为课程的一部分。对受试者进行评估,直到观察到表现达到稳定状态。主观上,参与者评估了他们对基于计算机模拟器的表现和看法。
在10名新手受试者(5名男性,5名女性)中,达到稳定表现状态所需的训练课程中位数为6次。随着模拟器使用时间的增加,表现有显著改善(P<0.001),然而,改善率随着时间下降。对完成时间的回归分析显示,一项膀胱镜检查任务存在显著的性别效应。在研究结束时,任何任务的性别表现差异均不显著。新手一致认为URO Mentor易于使用,并提供了总体逼真的训练体验。
在本研究中,基于计算机的模拟器成功纳入了膀胱镜检查教育的培训课程。对于使用刚性和柔性膀胱镜执行的模拟任务,需要进行6次训练课程的中位数。客观上,测试场景中的表现随着经验的增加而显著提高。基于主观的未经验证的标准,舒适度和感知能力从课程前评估到课程后评估有显著提高。
