A previous study in 2016 found that the quality of YouTube videos on epistaxis first-aid management was highly variable. This study aimed to reassess the accuracy and patient understandability of such YouTube videos.
YouTube was searched using the phrase 'How to stop a nosebleed'. The highest 50 ranking videos, based on relevance, were screened. Each video was assessed objectively using a standardised 'advice score', and subjectively using a video understandability and actionability checklist, the Patient Education Materials Assessment Tool for Audiovisual Materials ('PEMAT-A/V').
The mean advice score was 4.1 out of 8. The mean (standard deviation) understandability and actionability scores were 76 per cent (17 per cent) and 89 per cent (18 per cent), respectively. There was a strong positive correlation between the actionability scores and the advice scores (ρ = 0.634; < 0.001), and between the actionability scores and the understandability scores (ρ = 0.519; = 0.002).
YouTube videos are providing increasingly relevant advice for patients seeking healthcare information. YouTube is proposed as a useful medium for teaching epistaxis management to patients and community practitioners.
2016 年的一项研究发现，YouTube 上关于鼻出血急救管理的视频质量差异很大。本研究旨在重新评估此类 YouTube 视频的准确性和患者理解度。
使用短语“如何止血”在 YouTube 上进行搜索。根据相关性，筛选出排名前 50 的最高视频。使用标准化的“建议评分”对每个视频进行客观评估，并使用视频易懂性和可操作性检查表（视听材料患者教育材料评估工具“PEMAT-A/V”）进行主观评估。
平均建议得分为 8 分中的 4.1 分。平均（标准差）易懂性和可操作性得分为 76%（17%）和 89%（18%）。可操作性得分与建议得分之间存在强烈的正相关关系（ρ=0.634；<0.001），可操作性得分与易懂性得分之间也存在强烈的正相关关系（ρ=0.519；=0.002）。
YouTube 视频为寻求医疗保健信息的患者提供了越来越相关的建议。YouTube 被提议作为向患者和社区从业者传授鼻出血管理知识的有用媒介。
