Quality and Content Analysis of Hallux Valgus Videos on YouTube®

YouTube as a source of information for pressure injury: Quality assessment and content analysis

We aimed to assess the quality and reliability of pressure injury-related videos uploaded on YouTube, analyse the sources and contents, and examine the correlation between video parameters. We searched YouTube using two keywords, "pressure ulcer" and "pressure sore", on August 20, 2022. We sorted the videos according to their number of views and included the top 100 videos for each keyword. The quality of videos was assessed using the Global Quality Scale (GQS), while their reliability was evaluated by the modified DISCERN (mDISCERN) tool. In addition, we evaluated the videos in which content was included, analysed the correlations and differences between GQS, mDISCERN, and video parameters. We initially found a total of 100 videos for each keyword and finally included and analysed 77 videos. The mean scores for the mDISCERN and GQS were 2.35 ± 0.98 and 3.09 ± 0.99, respectively. Both GQS and mDISCERN showed statistically significant correlations with each other (rho = 0.54, p < 0.0001*) and with the length of the videos, respectively (rho = 0.36, p = 0.001*), (rho = 0.29, p = 0.01*). Of the videos created by physicians, 8 (57.1%) included content related to treatment, while of the videos created by nonphysician health personnel, 22 (57.9%) included content related to prevention. Analysing whether there were differences in video parameters based on the sources, we observed significant differences between sources in GQS (p < 0.0001*), mDISCERN (p < 0.0001*), and video length (p = 0.001*). In the post-hoc analysis, videos uploaded by physicians or nonphysician health personnel showed higher quality and reliability than videos uploaded by other sources. Therefore, the results of this study could be useful for healthcare providers, as well as patients and caregivers, to search for high-quality and reliable YouTube videos related to pressure injury.

Users' experience with health-related content on YouTube: an exploratory study

BACKGROUND

This study focuses on health-related content (HRC) on YouTube and addresses the issue of misinformation on this platform. While previous research centered on content evaluations by experts, this study takes a user-centered approach and aims to explore users' experiences with and perceptions of HRC videos and to establish links between these perceptions and some socio-demographic characteristics including age, gender, profession, and educational level.

METHODS

A quantitative research design was used in the study. 3,000 YouTube users responded to a 35-item anonymous questionnaire to collect information about the content they watch toward decision-making, their perceptions of the usefulness and bias of this content, what they identify as quality indicators for HRC, and what they recommend to improve the quality of such content on YouTube. The data were analyzed using descriptive statistics, frequency, and correlation analyses.

RESULTS

The results reveal that 87.6 percent (n=2630) of the participants watch HRC on YouTube, and 84.7 percent (n=2542) make decisions based on what they watch. Exercise and bodybuilding videos are the most popular, with over half of the participants watching them. 40 percent of the users watch YouTube videos to decide whether to consult a doctor or adopt specific health-related practices. In contrast to evaluations by experts in previous studies, most respondents perceive HRC videos on YouTube as useful and do not find connections between video quality and surface features like the number of views and likes. Weak or no correlations were observed between the perceived usefulness of HRC videos and age, gender, profession, or educational level. Participants' recommendations for enhancing HRC quality align with previous research findings.

CONCLUSIONS

Users turn to YouTube not only for health information but also as a decision-making tool. Combined with their generally positive attitudes towards content quality on this platform, this can have significant consequences for their health. Follow-up studies are needed to get more insights into decision-making behaviors and how users assess their decisions in retrospect.

A cross-sectional study on reliability and quality of YouTube® videos related to hallux valgus and evaluation of newly developed hallux valgus-specific survey tool

Objective

Previous studies have reported low quality and reliability on YouTube videos about various medical issues including videos related to hallux valgus (HV) treatment. Therefore, we aimed to evaluate the reliability and quality of YouTube videos on HV and develop a new HV-specific survey tool that physicians, surgeons, and the medical industry can use to create high-quality videos.

Methods

Videos viewed over 10,000 times were included in the study. We used the Journal of the American Medical Association (JAMA) benchmark criteria, global quality score (GQS), DISCERN tool, and new HV-specific survey criteria (HVSSC) developed by us to evaluate the quality, educational utility and reliability of the videos, the popularity of which was assessed using the Video Power Index (VPI) and view ratio (VR).

Results

Fifty-two videos were included in this study. Fifteen videos (28.8%) were posted by medical companies producing surgical implants and orthopedic products, 20 (38.5%) by nonsurgical physicians, and 16 (30.8%) by surgeons. The HVSSC indicated that the quality, educational value, and reliability of only 5 (9.6%) videos were adequate. Videos posted by physicians and surgeons tended to be more popular (p = 0.047 and 0.043). Although no correlation was detected among the DISCERN, JAMA, and GQS scores, or between the VR and VPI, we found correlations of the HVSSC score with the number of views and the VR (p = 0.374 and p = 0.006, respectively). A good correlation was detected among the DISCERN, GQS, and HVSSC classifications (rho = 0.770, 0.853, and 0.831, respectively, p = 0.001).

Conclusions

The reliability of HV-related videos on YouTube is low for professionals and patients. The HVSSC can be used to evaluate the quality, educational value, and reliability of videos.
