No useful comparative data exist on the relative realism of commercially available devices for simulating colonoscopy.
To develop an instrument for quantifying realism and provide the first wide-ranging empiric comparison.
Repeated measures, observational study. Nineteen experienced colonoscopists completed cases on 4 colonoscopy simulators (AccuTouch, GI Mentor II, Koken, and Kyoto Kagaku) and evaluated each device.
A medical simulation center in a large tertiary hospital.
For each device, colonoscopists completed the newly developed Colonoscopy Simulator Realism Questionnaire (CSRQ), which contains 58 items grouped into 10 subscales measuring the realism of different aspects of the simulation. Subscale scores are weighted and combined into an aggregated score, and there is also a single overall realism item.
Overall, current colonoscopy simulators were rated as only moderately realistic compared with real human colonoscopy (mean aggregated score, 56.28/100; range, 48.39-60.45, where 0 = "extremely unrealistic" and 100 = "extremely realistic"). On both overall realism measures, the GI Mentor II was rated significantly less realistic than the AccuTouch, Kyoto Kagaku, and Koken (P < .001). There were also significant differences between simulators on 9 subscales, and the pattern of results varied between subscales.
The study was limited to commercially available simulators, excluding ex-vivo models. The CSRQ does not assess simulated therapeutic procedures.
The CSRQ is a useful instrument for quantifying simulator realism. There is no clear "first choice" simulator among those assessed. Each has unique strengths and weaknesses, reflected in the differing results observed across 9 subscales. These findings may facilitate the targeted selection of simulators for various aspects of colonoscopy training.
目前尚无关于模拟结肠镜检查的商业可用设备的相对逼真度的有用比较数据。
开发一种用于量化逼真度的仪器，并提供首次广泛的经验比较。
重复测量，观察性研究。19 名经验丰富的结肠镜检查医师在 4 种结肠镜模拟设备（AccuTouch、GI Mentor II、Koken 和 Kyoto Kagaku）上完成了病例，并对每种设备进行了评估。
一家大型三级医院的医学模拟中心。
对于每种设备，结肠镜检查医师完成了新开发的结肠镜模拟逼真度问卷（CSRQ），其中包含 58 个项目，分为 10 个子量表，用于测量模拟的不同方面的逼真度。子量表分数进行加权并组合成一个综合分数，还有一个单一的整体逼真度项目。
总体而言，与真实的人类结肠镜检查相比，当前的结肠镜模拟设备的逼真度仅为中等（平均综合评分，56.28/100；范围，48.39-60.45，其中 0 表示“非常不真实”，100 表示“非常真实”）。在这两个整体逼真度指标上，GI Mentor II 的评分均明显低于 AccuTouch、Kyoto Kagaku 和 Koken（P<.001）。在 9 个子量表上，模拟设备之间也存在显著差异，结果模式因子量表而异。
该研究仅限于商业上可用的模拟设备，不包括离体模型。CSRQ 不评估模拟治疗程序。
CSRQ 是一种用于量化模拟器逼真度的有用工具。在所评估的设备中，没有明确的“首选”模拟器。每个模拟器都有独特的优势和劣势，这反映在 9 个子量表观察到的不同结果中。这些发现可能有助于针对结肠镜检查培训的各个方面有针对性地选择模拟器。
