Quality assessment of shock videos on video sharing platforms:A Cross-Sectional Study
ABSTRACT
Background:
As a highly lethal circulatory failure syndrome, the pathophysiological mechanisms of shock can lead to multiple organ dysfunction syndrome (MODS), which significantly increases the demand for intensive care and the length of hospitalisation.）There is an urgent need for the public to be informed about health-related issues. In recent years, short videos have become a significant medium for health education, and this study aimed to evaluate shock-related videos on short video sharing platforms.
Objective:
Assess the quality of the short video dissemination about shock.
Methods:
Videos featuring shocking content were retrieved from three short video-sharing platforms: TikTok, Bilibili, and Xiaohongshu. The Global Quality Score (GQS) and mDISCERN tools were utilised to evaluate the credibility and quality of the videos, in addition to employing the Patient Education Materials Evaluation Tool for Audiovisual Content (PEMAT-A/V). Finally, the video was evaluated by examining disease definitions, clinical signs and symptoms, risk factors, assessment, management, and outcomes.
Results:
A total of 244 short videos were retrieved from the three platforms.The overall video quality was found to be moderately low. The individual video sources of the GQS were of lower quality (1-3), and the mDISCERN scores were moderate (2-4)，with health advocates demonstrating the highest level of quality, followed by health professionals as the second most proficient.The PEMAT A/V scores were as follows: 91% of the overall comprehensibility scores were greater than 60, 65% of the operability scores were greater than 60, and 73% of the overall levels were greater than 60. The definition of shock and its clinical signs and symptoms were clearly explained in 172 videos (70.4%), and in 137 videos (56.1%), respectively.
Conclusions:
he analysis revealed that the content and information quality of the videos was, overall, not satisfactory. This underscores the necessity for relevant authorities to oversee the quality of health-related short videos, thereby assisting the public in the early prevention and treatment of diseases. Clinical Trial: no
