To assess the alignment of YouTube® videos providing dietary recommendations for gout with evidence-based guidelines targeted at the United Kingdom (UK) population and to establish their quality.
A content analysis of YouTube® videos providing dietary recommendations for gout was undertaken. Videos were categorised by video source. Each video's dietary recommendations for gout were compared with three evidence-based guidelines for gout, producing a compliance score. Presence of non-guideline advice was assessed. Understandability and actionability were evaluated using the Patient Education Material Assessment Tool for Audio-Visual Materials. Reliability was assessed using an adapted-DISCERN tool and educational quality using the Global Quality Score Five-Point Scale. Differences between video source and continuous variables were assessed using one-way Kruskal-Wallis H tests. For categorical variables, associations were investigated using Fisher-Freeman-Halton tests.
Online, May-June 2020.
One-hundred thirty-one videos.
Alignment of videos with evidence-based guidelines was poor (median compliance score 27 % (interquartile range 17-37 %)). Additionally, 57 % of videos contained non-guideline advice. The health professional source group had the fewest videos containing non-guideline advice, but this was only significantly lower than the naturopath group (31 % . 81 %, = 0·009). Almost 70 % of videos were considered poorly actionable and 50 % poorly understandable. Most videos were rated poor for reliability (79 %) and poor to generally poor for educational quality (49 %).
YouTube videos providing dietary recommendations for gout frequently fail to conform to evidence-based guidelines, and their educational quality, reliability, understandability and actionability are often poor. More high-quality, comprehensive, evidence-based YouTube videos are required for UK gout patients.
评估针对英国（UK）人群提供痛风饮食建议的 YouTube®视频与针对痛风的循证指南的一致性，并确定其质量。
对提供痛风饮食建议的 YouTube®视频进行内容分析。根据视频来源对视频进行分类。将每个视频的痛风饮食建议与三种针对痛风的循证指南进行比较，得出符合率。评估非指南建议的存在。使用视听材料患者教育材料评估工具评估可理解性和可操作性。使用经过改编的 DISCERN 工具评估可靠性，并使用全球质量评分五分制评估教育质量。使用单向 Kruskal-Wallis H 检验评估视频来源与连续变量之间的差异。对于分类变量，使用 Fisher-Freeman-Halton 检验进行关联研究。
线上，2020 年 5 月至 6 月。
131 个视频。
视频与循证指南的一致性较差（中位数符合率为 27%（四分位距 17%至 37%））。此外，57%的视频包含非指南建议。专业健康人员来源组中包含非指南建议的视频最少，但这仅明显低于顺势疗法医生组（31%. 81%， = 0·009）。近 70%的视频被认为难以操作，50%的视频难以理解。大多数视频的可靠性评分较差（79%），教育质量评分较差至一般较差（49%）。
提供痛风饮食建议的 YouTube 视频经常不符合循证指南，其教育质量、可靠性、可理解性和可操作性往往较差。英国痛风患者需要更多高质量、全面、基于循证的 YouTube 视频。
