目的：窄带成像（NBI）是一种广泛使用的内窥镜成像技术;然而，该技术的使用率有待提高。在为期一天的研讨会中，教授新的成像技术和评估学员的表现可能是一项具有挑战性的练习。为了支持NBI培训，我们开发了一个在线培训工具（Medimq），以帮助专家培训NBI支气管镜检查的新手，该工具可以评估学员的表现并在为期1天的课程结束前提供反馈。本研究确定是否受训者的能力，以确定相关的病理增加与建议的互动测试方法。研究方法：两组20名和18名支气管镜医师参加了NBI课程，他们在主讲座前后进行了前测和后测，并在4周后进行了随访测试，以测量知识的保留率。我们测量了他们在支气管镜NBI图像上标记正常和异常“活检尺寸”区域进行活检的能力。这些标记与专家在同一图像上标记的区域进行了比较。结果：第一组结果用于预试。经过修改后，第2组的改进测试结果显示，受训者在检测正常或异常区域方面提高了32%（总类平均归一化增益）。在后续测试中，第2组改善了23%。结论：全班平均归一化增益为32%，表明我们的测试可以用于提高学员分析NBI图像的能力。测试方法（和工具）可用于测量4周后的随访。如果学员在课程结束后能更频繁地练习，后续测试结果可望更好。
Objectives: Narrow-band imaging (NBI) is a widely available endoscopic imaging technology; however, uptake of the technique could be improved. Teaching new imaging techniques and assessing trainees’ performance can be a challenging exercise during a 1-day workshop. To support NBI training, we developed an online training tool (Medimq) to help experts train novices in NBI bronchoscopy that could assess trainees’ performance and provide feedback before the close of the 1-day course. The present study determines whether trainees’ capacity to identify relevant pathology increases with the proposed interactive testing method. Methods: Two groups of 20 and 18 bronchoscopists have attended an NBI course where they did a pretest and post-test before and after the main lecture, and a follow-up test 4 weeks later to measure retention of knowledge. We measured their ability to mark normal and abnormal ‘biopsy size’ areas on bronchoscopic NBI images for biopsy. These markings were compared with areas marked by experts on the same images. Results: The first group results were used to pilot the test. After modifications, the results of the improved test for group 2 showed trainees improved by 32% (total class average normalized gain) in detecting normal or abnormal areas. On follow-up testing, Group 2 improved by 23%. Conclusions: The overall class average normalized gain of 32% shows our test can be used to improve trainees’ competency in analyzing NBI Images. The testing method (and tool) can be used to measure the follow up 4 weeks later. Better follow-up test results would be expected with more frequent practice by trainees after the course.
