BACKGROUND
Heart failure (HF) is a complex and life-threatening syndrome associated with significant morbidity and mortality. While TikTok has gained popularity as a social media platform for sharing HF-related information, the quality of such content on TikTok remains unexplored.
METHODS
A cross-sectional analysis was conducted on TikTok videos related to HF in China. The sources of the videos were identified and analyzed. The content comprehensiveness of the videos was evaluated using six questions that covered definition, signs and symptoms, risk factors, evaluation, management, and outcomes. The reliability and quality of the videos were assessed using three standardized evaluation instruments: DISCERN, JAMA benchmarks, and the Global Quality Scale. Additionally, the correlation between video quality and video characteristics was further investigated.
RESULTS
Among the video sources, 92.2% were attributed to health professionals, while news agencies and non-profit organizations accounted for 5.7% and 2.1%, respectively. The content comprehensiveness score for the videos was 3.36 (SD 3.56), with news agencies receiving the highest scores of 4.06 (SD 3.31). The median DISCERN, JAMA, and GQS scores for all 141 videos were 26.50 (IQR 25.00-28.750), 2.00 (IQR 2.00-2.00), and 2.00 (IQR 2.00-2.00), respectively. Videos from health professionals had significantly higher JAMA scores compared to those from non-profit organizations ( < 0.01). Correlation analysis between video quality and video characteristics showed positive correlations between content comprehensiveness scores and video duration ( = 0.420, < 0.001), number of comments ( = 0.195, < 0.05), and number of shares ( = 0.174, < 0.05). GQS scores were negatively or positively correlated with the number of days since upload ( = -0.212, < 0.05) and video duration ( = 0.442, < 0.001).
CONCLUSION
The overall quality of the videos was found to be unsatisfactory, with variations in quality scores observed across different video sources. Content comprehensiveness was inadequate, the reliability and quality of the information presented in the videos was questionable. As TikTok continues to grow as a platform for health information, it is essential to prioritize accuracy and reliability to enhance patients' self-care abilities and promote public health.
背景
心力衰竭（HF）是一种复杂且危及生命的综合征，与显著的发病率和死亡率相关。虽然 TikTok 已作为一个分享与 HF 相关信息的社交媒体平台广受欢迎，但 TikTok 上此类内容的质量仍未得到探索。
方法
对中国与 HF 相关的 TikTok 视频进行了横断面分析。确定了视频的来源并进行了分析。使用涵盖定义、体征和症状、危险因素、评估、管理和结局的六个问题来评估视频内容的全面性。使用三个标准化评估工具（DISCERN、JAMA 基准和全球质量量表）评估视频的可靠性和质量。此外，还进一步调查了视频质量与视频特征之间的相关性。
结果
视频来源中，92.2%归因于卫生专业人员，而新闻机构和非营利组织分别占 5.7%和 2.1%。视频内容的全面性评分为 3.36（SD 3.56），新闻机构的得分最高，为 4.06（SD 3.31）。141 个视频的平均 DISCERN、JAMA 和 GQS 评分为 26.50（IQR 25.00-28.750）、2.00（IQR 2.00-2.00）和 2.00（IQR 2.00-2.00）。与非营利组织相比，卫生专业人员的视频 JAMA 得分明显更高（ < 0.01）。视频质量与视频特征之间的相关性分析显示，内容全面性评分与视频时长（ = 0.420， < 0.001）、评论数（ = 0.195， < 0.05）和分享数（ = 0.174， < 0.05）呈正相关。GQS 评分与上传后天数（ = -0.212， < 0.05）和视频时长（ = 0.442， < 0.001）呈负相关或正相关。
结论
发现视频整体质量不尽如人意，不同视频来源的质量评分存在差异。内容全面性不足，视频中呈现信息的可靠性和质量值得怀疑。随着 TikTok 作为健康信息平台继续发展，必须优先考虑准确性和可靠性，以提高患者的自我护理能力并促进公众健康。
