YouTube online videos as a source for patient education of cervical spondylosis-a reliability and quality analysis

Video Quality Assessment and Analysis of Gastroesophageal Reflux Disease on TikTok and Bilibili: Cross-Sectional Study

Aims and Objectives

To assess the content quality and reliability of Gastroesophageal reflux disease (GERD) videos on TikTok and Bilibili.

Background

Since many people with GERD use current online platforms to search for health information, there is a need to assess the quality of GERD videos on social media. There are many GERD videos on TikTok and Bilibili; however, the quality of information in these videos remains unknown.

Design

A cross-sectional survey on two video platforms.

Methods

In November 2023, we retrieved 200 videos from TikTok and Bilibili with the search term "GERD." Basic video information was extracted, the content coded, and the video source identified. Two independent raters assessed the quality of each video using the Journal of the American Medical Association (JAMA) benchmark criteria, the modified DISCERN (mDISCERN) criteria, and the Global Quality Score (GQS) tool.

Results

A total of 156 videos were collected. Most of the videos on TikTok and Bilibili came from gastroenterologists. TikTok's GERD video quality and reliability were higher than Bilibili's. The mDISCERN and GQS scores of both platforms were positively correlated with duration, and the GQS score was positively correlated with collection and shares. Bilibili's JAMA score was negatively correlated with time-sync comments, and TikTok's JAMA score was negatively correlated with days since upload.

Conclusion

This study indicated that the content quality scores of TikTok and Bilibili as sources of scientific information on GERD are average, and patients should carefully identify and select to watch GERD-related videos on TikTok and Bilibili.

Relevance to Clinical Practice

By evaluating the quality of videos on GERD on the two platforms, this can provide new ideas for health education interventions in the clinic and a relevant basis for improving the quality level of the videos.

Assessing quality and reliability of online videos on tachycardia: a YouTube video-based study

BACKGROUND

Considering the adverse clinical consequences of pathologic tachycardia and the potential anxiety caused by physiological tachycardia in some heathy individuals, it is imperative to disseminate health information related to tachycardia for promotion in early diagnosis and appropriate management. YouTube has been increasingly used to access health care information. The aim of this study is to assess the quality and reliability of English YouTube videos focusing on tachycardia and further delve into strategies to enhance the quality of online health resources.

METHODS

We conducted a search using the specific key words "tachycardia" in YouTube online library on December 2, 2023. The first 150 videos, ranked by "relevance", were initially recorded. After exclusions, a total of 113 videos were included. All videos were extracted for characteristics and categorized based on different topics, sources or contents. Two independent raters assessed the videos using Journal of American Medical Association (JAMA) benchmark criteria, Modified DISCERN (mDISCERN) tool, Global Quality Scale (GQS) and Tachycardia-Specific Scale (TSS), followed by statistical analyses. All continuous data in the study were presented as median (interquartile range).

RESULTS

The videos had a median JAMA score of 2.00 (1.00), mDISCERN of 3.00 (1.00), GQS of 2.00 (1.00), and TSS of 6.00 (4.50). There were significant differences in JAMA (P < 0.001), mDISCERN (P = 0.004), GQS (P = 0.001) and TSS (P < 0.001) scores among different sources. mDISCERN (P = 0.002), GQS (P < 0.001) and TSS (P = 0.030) scores significantly differed among various contents. No significant differences were observed in any of the scores among video topics. Spearman correlation analysis revealed that VPI exhibited significant correlations with quality and reliability. Multiple linear regression analysis suggested that longer video duration, sources of academics and healthcare professionals were independent predictors of higher reliability and quality, while content of ECG-specific information was an independent predictor of lower quality.

CONCLUSIONS

The reliability and educational quality of current tachycardia-related videos on YouTube are low. Longer video duration, sources of academics and healthcare professionals were closely associated with higher video reliability and quality. Improving the quality of internet medical information and optimizing online patient education necessitates collaborative efforts.

YouTube as a Source of Information on Public Health Ethics

BACKGROUND

Public health ethics (PHE) is a dynamic area within bioethics that addresses the complex moral implications of public health measures in the face of growing health threats. YouTube is a powerful and widely used platform for disseminating health-related information. The primary objective of this study is to assess videos related to PHE on YouTube. The aim is to gauge the extent of misinformation in collecting PHE videos on the platform.

METHODS

On October 25, 2023, a thorough investigation on YouTube was undertaken, employing pre-determined search phrases involving 'public health,' 'healthcare,' 'health services administration,' and 'health policy and ethics.' The research encompassed a total of 137 videos that were selected according to strict inclusion and exclusion criteria. The videos were evaluated using the Global Quality Scale to measure quality and the modified DISCERN tool to evaluate reliability. The researchers identified video sources and compared several video attributes across different quality groups.

RESULTS

A total of 137 videos were analyzed, and 65 (47.45%) were classified as high quality, 52 (37.23%) as moderate quality, and 21 (15.32%) as low quality. In high-quality videos, academic, government, physician, and university-hospital sources predominated, whereas Internet users and news sources were connected with low-quality videos. Significant differences in DISCERN score, per day views, likes, and comments were seen across the quality groups (P = 0.001 for views per day and P = 0.001 for other characteristics). According to the findings, low-quality videos had higher median values for daily views, likes, and comments.

CONCLUSION

Although nearly half of the videos were high-quality, low-quality videos attracted greater attention. Critical contributors to high-quality videos included academic, government, physician, and university-hospital sources. The findings highlight the importance of quality control methods on social media platforms and strategies to direct users to trustworthy health information. Authors should prioritize appropriate citations and evaluate YouTube and other comparable platforms for potential promotional low-quality information.

Judicious use of the YouTube platform as a complementary source of reliable medical information for physiotherapy students — a paradigm shift in educational methodology during the COVID-19 pandemic

: Background. The COVID-19 pandemic has imposed a paradigm shift in the pedagogical methodology for a resilient medical educational university system. The epidemiological context has imposed a large-scale closure of universities and disturbed traditional methods of teaching and learning (the direct face-to-face patient-student clinical interactions). Social networks such as the YouTube platform seemed to be a complementary source for medical information, providing a modern, viable e-health strategy for physiotherapy students. Only nine studies addressed rehabilitation in various pathologies, but none of them analyzed the quality of videos focusing on neuraxial rehabilitation. Methods. During the 2021–2022 academic year, six undergraduate license theses focused on the frequently encountered pathology in the Neuromuscular Rehabilitation Clinic of TEHBA: rehabilitation after spinal cord injury, stroke, Parkinson`s disease, and disk hernia. The studies started with the hypothesis that the materials posted on the YouTube platform might have variable-quality content depending on the provider who posted the film. The students were given guidance to search for and select the videos and instructions to use the DISCERN and global quality (GQS) scales and to classify the technical and scientific features of each item using descriptive analysis. These qualitative Likert scales assess several video parameters, including the audio-visual flow, the content's medical knowledge value, and its applicability to physiotherapy students. Given the use of public-domain videos available to the general public and posted in the mass media on the YouTube platform, the approval of the Ethical Council was not necessary. Results. Each movie's scientific content was assessed according to its significance, relevance, and clarity. Videos posted to the YouTube platform by healthcare professionals (including experienced physiotherapists), healthcare institutions, and academic health organizations achieved the highest DISCERN and GQS scores compared to other video sources. Videos posted by vloggers (independent authors or patients) received the lowest reliability and quality scores. Discussion. The article presents a timely and relevant study on integrating digital tools in medical education. Although many YouTube videos with kinesiotherapy and rehabilitation content have offered valuable information, students and younger residents should be aware that the social platform sometimes fails to provide high-quality content. YouTube administrators, vloggers, and publishers should use validity scales (such as DISCERN and GQS) as standard guides for quality self-control and promote reliable, evidence-based medical information. Conclusions. A judicious use of e-health education and social media platforms during the COVID-19 pandemic represented complementary sources of reliable medical information for physiotherapy students.
