An increasing number of patients are investigating health information by using the Internet because of its exponential growth. Therefore, it is important to test the accuracy of the information presented to determine which information should not be shared. This study investigated the information available on YouTube with regard to disc herniation.
The first 50 videos found after the keyword "disc herniation" was used in the YouTube search engine were included in the study. Video popularity was evaluated with an index called the video power index (VPI). The quality and accuracy of the information were evaluated by 2 independent spinal surgeons using the Journal of American Medical Association (JAMA) score and the DISCERN scoring system. Interobserver agreement and individual correlations of the data of each video were statistically analyzed.
Of the 50 videos evaluated, 16 (32%) contained animation and 34 (64%) contained real images. The mean duration was 6.587 minutes, and the mean view was 423.472. The mean DISCERN score was 30.7 (±10.3), and the mean JAMA score was 1.8 (±0.5). There was good agreement between the 2 researchers in terms of DISCERN and JAMA scores. No statistically significant correlation was found between the JAMA and DISCERN scores of both researchers and VPI values, video lengths, animation, or real images.
The quality of the disc herniation information offered on YouTube is low. The evaluation of medical information obtained from the Internet by health professionals is an important step in guiding the correct flow of medical information to patients.
由于互联网呈指数级增长，越来越多的患者通过互联网查询健康信息。因此，测试所提供信息的准确性以确定哪些信息不应分享非常重要。本研究调查了YouTube上关于椎间盘突出症的可用信息。
在YouTube搜索引擎中使用关键词“椎间盘突出症”后找到的前50个视频被纳入研究。视频受欢迎程度通过一个名为视频影响力指数（VPI）的指标进行评估。两名独立的脊柱外科医生使用《美国医学会杂志》（JAMA）评分和DISCERN评分系统对信息的质量和准确性进行评估。对每个视频数据的观察者间一致性和个体相关性进行统计分析。
在评估的50个视频中，16个（32%）包含动画，34个（64%）包含真实图像。平均时长为6.587分钟，平均观看次数为423.472次。平均DISCERN评分为30.7（±10.3），平均JAMA评分为1.8（±0.5）。两位研究人员在DISCERN评分和JAMA评分方面具有良好的一致性。两位研究人员的JAMA评分和DISCERN评分与VPI值、视频长度、动画或真实图像之间均未发现统计学上的显著相关性。
YouTube上提供的椎间盘突出症信息质量较低。健康专业人员对从互联网获取的医学信息进行评估是引导医学信息正确流向患者的重要一步。
