NOTE: This is an unreviewed Preprint
Warning: This is a unreviewed preprint (What is a preprint?). Readers are warned that the document has not been peer-reviewed by expert/patient reviewers or an academic editor, may contain misleading claims, and is likely to undergo changes before final publication, if accepted, or may have been rejected/withdrawn (a note "no longer under consideration" will appear above).
Peer review me: Readers with interest and expertise are encouraged to sign up as peer-reviewer, if the paper is within an open peer-review period (in this case, a "Peer Review Me" button to sign up as reviewer is displayed above). All preprints currently open for review are listed here. Outside of the formal open peer-review period we encourage you to tweet about the preprint.
Citation: Please cite this preprint only for review purposes or for grant applications and CVs (if you are the author).
Final version: If our system detects a final peer-reviewed "version of record" (VoR) published in any journal, a link to that VoR will appear below. Readers are then encourage to cite the VoR instead of this preprint.
Settings: If you are the author, you can login and change the preprint display settings, but the preprint URL/DOI is supposed to be stable and citable, so it should not be removed once posted.
Submit: To post your own preprint, simply submit to any JMIR journal, and choose the appropriate settings to expose your submitted version as preprint.
Warning: This is an author submission that is not peer-reviewed or edited. Preprints - unless they show as "accepted" - should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Sepsis-Related Short Videos Across Popular Social Media Platforms: A Mixed-Methods Study
ABSTRACT
Background:
Sepsis is a major global health concern, particularly given its high morbidity and mortality rates. Despite its clinical significance, the public awareness of sepsis remains limited.
Objective:
Therefore, since short videos are increasingly becoming a vital medium for health education, we aimed to systematically assess sepsis-related short videos’ content quality, information coverage, and dissemination performance across major social media platforms, as well as to identify the key factors influencing their communication effectiveness and educational utility.
Methods:
This mixed-methods study integrated questionnaire data and video content analyses. The questionnaires were distributed among 200 participants to assess sepsis awareness and short video usage preferences. Meanwhile, 140 sepsis-related videos were collected from TikTok, Bilibili, and WeChat and evaluated using the Global Quality Score (GQS), the modified DISCERN tool, and a six-dimension content coverage framework. Finally, communication performance was assessed through user engagement metrics and other related indicators.
Results:
Compared to videos from the media or individual publishers, physician-produced videos had significantly higher GQS and DISCERN scores (p < 0.001). Additionally, the Intensive Care Unit (ICU) and chief physicians produced the highest-quality content. Furthermore, high-quality videos (GQS > 3, DISCERN > 3) correlated with greater content retention and diffusion. We also noted a mismatch between the content provided and public information needs. Specifically, practical topics such as symptoms and prevention were underrepresented. Additionally, although emotional elements and clickbait-style titles moderately enhanced engagement, they did not substitute for content quality. Moreover, various platform-specific benefits were identified including TikTok facilitating rapid exposure, Bilibili supporting structured learning, and WeChat enabling socially driven redistribution.
Conclusions:
Although short video platforms hold great promise for sepsis education, challenges of inconsistent quality, limited coverage, and misalignment with audience needs persist in current content. Therefore, enhancing professional accuracy, optimizing structural design, and tailoring strategies to platform characteristics would improve the educational impact of the videos, ultimately promoting early sepsis diagnosis and treatment.
