Otoscopy examination can be challenging. Traditional teaching uses still image illustrations. Newer attempts use video samples to simulate the otoscopy exam which is a dynamic process.Aims/Objective: To assess whether recorded otoscopy videos from a smartphone adaptable otoscope can be used to develop a video-based otoscopy quiz which may be used for instructing and familiarizing participants to normal anatomy and pathologic ear conditions. To use this quiz to assess current pediatric residents' competency of common otoscopy diagnosis.
This study was conducted in 2018. Video samples of ear pathology were collected at the Albany Medical Center using a smartphone adaptable otoscope- Cellscope. The videos were used to create a video otoscopy quiz (VOQ) without clinical vignettes. 45 pediatric residents from 3 academic institutions were evaluated with the quiz.
The weighted mean for the VOQ was 66.90% (95%CI 58.89%-68.42%). The breakdown by questions are: myringosclerosis 72.88%, retraction pocket 80.65%, cholesteatoma 42.22%, hemotympanum 75.04%, tympanic membrane perforation 79.62%, cerumen impaction 95.46%, otitis externa 52.54%, otitis media with effusion 63.30%, acute otitis media 75.55%, normal ear 36.39%.
We found that videos of otoscopy exams can be obtained with a smartphone adaptable otoscope and validated to develop a video-based quiz, which may be used to supplement otoscopic instruction. Following our testing process, we found pediatric residents are relatively well equipped to identify ear pathology on VOQ.
耳镜检查可能具有挑战性。传统教学使用静态图像插图。较新的尝试使用视频样本模拟耳镜检查这一动态过程。
评估来自智能手机适配耳镜的耳镜检查录像是否可用于开发基于视频的耳镜检查测验，该测验可用于指导参与者熟悉正常耳部解剖结构和病理性耳部情况，并用于评估当前儿科住院医师对常见耳镜诊断的能力。
本研究于2018年进行。在奥尔巴尼医学中心使用智能手机适配耳镜——Cellscope收集耳部病理视频样本。这些视频被用于创建一个没有临床病例描述的视频耳镜检查测验（VOQ）。对来自3个学术机构的45名儿科住院医师进行了该测验评估。
VOQ的加权平均分为66.90%（95%置信区间58.89%-68.42%）。各问题的得分情况如下：鼓膜硬化72.88%，内陷袋80.65%，胆脂瘤42.22%，血鼓室75.04%，鼓膜穿孔79.62%，耵聍栓塞95.46%，外耳道炎52.54%，中耳积液63.30%，急性中耳炎75.55%，正常耳36.39%。
我们发现使用智能手机适配耳镜可以获取耳镜检查视频，并验证其可用于开发基于视频的测验，该测验可用于补充耳镜检查教学。经过我们的测试过程，我们发现儿科住院医师在VOQ上识别耳部病理情况的能力相对较强。
