Web-based short-form videos are increasingly popular for disseminating fire and burn prevention information, but their content quality is unknown.
We aimed to systematically assess the characteristics, content quality, and public impact of web-based short-form videos offering primary and secondary (first aid) prevention recommendations for fires and burns in China between 2018 and 2021.
We retrieved short-form videos offering both primary and secondary (first aid) information to prevent fire and burn injuries published on the 3 most popular web-based short-form video platforms in China: TikTok, Kwai, and Bilibili. To assess video content quality, we calculated the proportion of short-form videos that included information on each of the 15 recommendations for burn prevention education from the World Health Organization (WHO; P) and that correctly disseminated each recommendation (P). High P and P indicated better content quality. To assess their public impact, we calculated the median (IQR) of 3 indicators: the number of comments, likes, and saves as a favorite by viewers. Chi-square test, trend chi-square test, and Kruskal-Wallis H test examined differences in indicators across the 3 platforms, years, content, and time duration of videos and between videos disseminating correct versus incorrect information.
Overall, 1459 eligible short-form videos were included. The number of short-form videos increased by 16 times between 2018 and 2021. Of them, 93.97% (n=1371) were about secondary prevention (first aid) and 86.02% (n=1255) lasted <2 minutes. The proportion of short-form videos including each of the 15 WHO recommendations ranged from 0% to 77.86% (n=1136). Recommendations 8, 13, and 11 had the highest proportions (n=1136, 77.86%; n=827, 56.68%; and n=801, 54.9%, respectively), whereas recommendations 3 and 5 were never mentioned. Among the short-form videos that included the WHO recommendations, recommendations 1, 2, 4, 6, 9, and 12 were always disseminated correctly, but the other 9 recommendations were correctly disseminated in 59.11% (120/203) to 98.68% (1121/1136) of videos. The proportion of short-form videos including and correctly disseminating the WHO recommendations varied across platforms and years. The public impact of short videos varied greatly across videos, with a median (IQR) of 5 (0-34) comments, 62 (7-841) likes, and 4 (0-27) saves as a favorite. Short-form videos disseminating correct recommendations had larger public impact than those disseminating either partially correct or incorrect knowledge (median 5 vs 4 comments, 68 vs 51 likes, and 5 vs 3 saves as a favorite, respectively; all P<.05).
Despite the rapid increase in the number of web-based short-form videos about fire and burn prevention available in China, their content quality and public impact were generally low. Systematic efforts are recommended to improve the content quality and public impact of short-form videos on injury prevention topics such as fire and burn prevention.
基于网络的短视频越来越受欢迎，用于传播火灾和烧伤预防信息，但这些视频的内容质量尚不清楚。
我们旨在系统评估 2018 年至 2021 年间中国发布的关于火灾和烧伤初级和（急救）预防建议的基于网络的短视频的特点、内容质量和公众影响力。
我们检索了在中国 3 个最受欢迎的基于网络的短视频平台（TikTok、快手上的 Kwai 和 B 站）上发布的提供初级和（急救）预防火灾和烧伤信息的短视频。为了评估视频内容质量，我们计算了包含世界卫生组织（WHO）15 项烧伤预防教育建议的短视频比例（P）和正确传播每个建议的比例（P）。高 P 和 P 表示更好的内容质量。为了评估其公众影响力，我们计算了 3 个指标的中位数（IQR）：评论、点赞和收藏的数量。卡方检验、趋势卡方检验和 Kruskal-Wallis H 检验用于检验 3 个平台、年份、内容和视频时长以及传播正确和不正确信息的视频之间的指标差异。
共纳入 1459 个合格短视频。2018 年至 2021 年间，短视频数量增加了 16 倍。其中，93.97%（n=1371）为二级预防（急救）短视频，86.02%（n=1255）时长<2 分钟。包含 WHO 15 项建议的短视频比例为 0%至 77.86%（n=1136）。建议 8、13 和 11 的比例最高（n=1136，77.86%；n=827，56.68%；n=801，54.9%），而建议 3 和 5 从未被提及。在包含 WHO 建议的短视频中，建议 1、2、4、6、9 和 12 总是正确传播，但其他 9 项建议在 59.11%（120/203）至 98.68%（1121/1136）的视频中得到正确传播。包含和正确传播 WHO 建议的短视频比例在不同平台和年份之间存在差异。短视频的公众影响力在视频之间差异很大，中位数（IQR）为 5（0-34）条评论、62（7-841）个赞和 4（0-27）个收藏。传播正确建议的短视频比传播部分正确或错误知识的短视频具有更大的公众影响力（中位数 5 条评论对 4 条评论，68 个赞对 51 个赞，5 个收藏对 3 个收藏，均 P<.05）。
尽管中国有关火灾和烧伤预防的基于网络的短视频数量迅速增加，但它们的内容质量和公众影响力普遍较低。建议系统地努力提高有关火灾和烧伤预防等伤害预防主题的短视频的内容质量和公众影响力。
