The study assessed the Global Quality Score (GQS) and informational engagement of users with YouTube videos on the Brazilian public health system (SUS). The YouTube video search tool was used with the Portuguese keywords 'unified health system' and 'SUS'. The first 100 videos returned in the search were studied, using the GQS to measure their educational value, usefulness, and information quality. Users' engagement with the videos was calculated based on their number of likes/reactions and comments. Other data collected were authorship, year of publication, topic approached, target audience, video length, and use of references. Two trained and calibrated researchers collected the data. Multiple analysis was performed with Logistic Regression, using a 95% confidence interval and significance of p<0.05. There were no poor or generally poor GQS scores (scores 1 and 2) and most videos (58%) achieved moderate or good scores (scores 3 and 4). Videos published after the onset of COVID-19 had a 70% lower chance of engagement than those published in pre-pandemic years (OR: 0.30; 95%CI: 0.12-0.74). Videos that targeted healthcare professionals were 72% less likely to achieve higher GQS scores, than those with an unidentified target audience (OR: 0.28; 95%CI: 0.10-0.75). The informational engagement of the videos showed fewer comments than likes/reactions. Most YouTube videos about the SUS had moderate or good global quality, which was associated with their period of publication and choice of target audience.
该研究评估了用户对巴西公共卫生系统（SUS）相关YouTube视频的全球质量得分（GQS）和信息参与度。使用YouTube视频搜索工具，输入葡萄牙语关键词“统一卫生系统”和“SUS”。对搜索结果中返回的前100个视频进行研究，使用GQS来衡量其教育价值、实用性和信息质量。根据视频的点赞/反应数量和评论来计算用户的参与度。收集的其他数据包括作者身份、出版年份、涉及的主题、目标受众、视频长度和参考文献的使用情况。两名经过培训和校准的研究人员收集数据。使用逻辑回归进行多分析，置信区间为95%，显著性水平为p<0.05。没有GQS得分低或普遍低的情况（得分1和2），大多数视频（58%）获得中等或良好得分（得分3和4）。在COVID-19疫情爆发后发布的视频，其参与度比疫情前发布的视频低70%（比值比：0.30；95%置信区间：0.12-0.74）。针对医疗保健专业人员的视频获得较高GQS得分的可能性比目标受众不明确的视频低72%（比值比：0.28；95%置信区间：0.10-0.75）。视频的信息参与度显示评论比点赞/反应少。大多数关于SUS的YouTube视频具有中等或良好的全球质量，这与它们的发布时间和目标受众的选择有关。
