BACKGROUND
the diagnostic accuracy of otitis media with effusion (OME) has been shown to be poor among medical students, residents, and practicing physicians.
OBJECTIVE
to determine if the use of pneumatic video-otoendoscopic examination (VOE) improves the diagnostic accuracy of OME among residents.
METHODS
pediatric residents were randomized into a "pneumatic" examination group (intervention) and a "still" examination group (control). The control group viewed a set of 25 still VOE images of the tympanic membranes of both normal and OME ears. The intervention group viewed the same still images but with the addition of pneumatic VOE assessments. Each resident documented each of his or her diagnoses as normal or OME. The accuracy of assessment for both the static and the pneumatic methods was compared.
RESULTS
twenty-nine pediatric residents participated in this study: 15 in the intervention group and 14 in the control group. The overall diagnostic accuracy was 91% for the intervention group versus 78% for the control group (p = .0003).
CONCLUSION
pneumatic video-otoscopy teaching improves the diagnostic accuracy of OME among residents.
背景
在医学生、住院医师和执业医师中，中耳炎（OME）的诊断准确性一直较差。
目的
确定气动视频耳镜检查（VOE）是否可以提高住院医师对OME 的诊断准确性。
方法
将儿科住院医师随机分为“气动”检查组（干预组）和“静态”检查组（对照组）。对照组观看了一组 25 张正常和OME 耳鼓膜的静态 VOE 图像。干预组观看了相同的静态图像，但增加了气动 VOE 评估。每位住院医师记录他或她的正常或OME 的诊断。比较了静态和气动方法的评估准确性。
结果
29 名儿科住院医师参加了这项研究：干预组 15 名，对照组 14 名。干预组的整体诊断准确性为 91%，而对照组为 78%（p = .0003）。
结论
气动视频耳镜检查教学可提高住院医师对OME 的诊断准确性。
