评估YouTube视频作为心力衰竭教育来源的可靠性

摘要(中文译文)

YouTube作为一个视频分享平台，有助于健康信息的传播。尽管社交媒体在心力衰竭照护中的作用尚不明确，但它可以增强互动、教育和参与，促进以患者为中心的照护，并鼓励治疗依从性和积极的健康管理。本研究旨在评估YouTube上与心力衰竭相关的视频作为患者信息来源的质量和可用性。共分析了100个关于心力衰竭的英文YouTube视频。视频根据上传者身份（医疗保健专业人员与非医疗保健专业人员）进行分类，并使用消费者健康信息质量标准、全球质量量表、美国医学会杂志标准和视频影响力指数进行评估。采用分位数回归分析以确定视频质量的独立预测因素。在分析的视频中，69%由医疗保健专业人员上传。消费者健康信息质量标准的平均得分为21分，全球质量量表为3分，美国医学会杂志标准为3分。来自专业人员的视频和时长较长的视频质量得分显著更高。分位数回归显示，视频时长可预测第75和第90百分位数的高全球质量量表值，而专业来源在大多数分位数中是一致性预测因素。研究发现，YouTube上关于心力衰竭的视频总体质量为低至中等，仍有很大的改进空间。然而，由医疗保健专业人员上传的视频在所有评估指标中均持续表现出更高的质量。较长的视频往往质量更高，但受欢迎程度与内容可靠性并不相关。应努力改进视频内容，以更好地进行患者教育。

Abstract

YouTube, a video-sharing platform, aids health information sharing, and while social media's role in heart failure care remains unclear, it can enhance interaction, education, and engagement, fostering patient-centered care and encouraging treatment adherence and active health management. The aim of the study was to evaluate the quality and usability of heart failure-related YouTube videos as a source of information for patients. A total of 100 English-language YouTube videos on heart failure were analyzed. Videos were categorized based on uploader identity (healthcare vs. non-healthcare professionals) and assessed using quality criteria for consumer health information, Global Quality Scale, Journal of the American Medical Association criteria, and Video Power Index. Quantile regression analysis was performed to identify independent predictors of video quality. Of the videos analyzed, 69% were uploaded by healthcare professionals. The mean quality criteria for consumer health information score was 21, Global Quality Scale was 3, and Journal of the American Medical Association was 3. Videos from professionals and longer videos had significantly higher quality scores. Quantile regression showed that video duration predicted high Global Quality Scale values at the 75th and 90th percentiles, while professional source was a consistent predictor across most quantiles. The overall quality of YouTube videos on heart failure was found to be low to moderate, with substantial room for improvement. Videos uploaded by healthcare professionals, however, consistently demonstrated higher quality across evaluation metrics. Longer videos tend to have higher quality, but popularity does not correlate with content reliability. Efforts should be made to improve video content for better patient education.
