YouTube videos as a source of information concerning Behçet's disease: a reliability and quality analysis.

In this study, we aimed to investigate the reliability and quality of YouTube videos concerning Behçet disease, for the first time in the literature. The most viewed 50 YouTube videos about Behçet disease were included. Study data used in the analysis included video length, image type, video content, uploaders, time since the date of upload, the number of total views, daily views, and the numbers of like, dislike and comments. The Video Power Index was used to determine popularity of the videos. Reliability and quality of the videos were evaluated using DISCERN and Global Quality Scale (GQS) instruments. The examined YouTube videos were divided into two groups as uploaded by professionals (physicians, health and hospital channels, institutions and societies) and non-professionals (patients, social organizations, others). Twenty-three (46%) videos were uploaded by professionals. The mean DISCERN score was found as 3.98 ± 0.77 in the videos uploaded by healthcare professionals and 2.83 ± 0.64 in those uploaded by non-professionals (p < 0.01). The mean GQS score was found as 4.09 ± 0.72 in the videos uploaded by healthcare professionals and 3.41 ± 0.69 in those uploaded by non-professionals (p < 0.01). 46% of the videos were of low-to-moderate reliability and 56% of low-to-moderate quality. Nearly half of the YouTube videos concerning Behçet disease were uploaded by non-physician sources with poor reliability and quality. Physicians should be encouraged to upload more professional videos to help and guide patients appropriately. YouTube videos should be subjected to an objective evaluation for content quality before they can be published.

Fiction, Falsehoods, and Few Facts: Cross-Sectional Study on the Content-Related Quality of Atopic Eczema-Related Videos on YouTube.

BACKGROUND: In recent years, YouTube has become a recognized source of medical information for health care consumers. Although YouTube has advantages in this context, there are potential dangers as videos may contain nonscientific, misleading, or even harmful information. OBJECTIVE: As little is known about YouTube as a source of information on atopic dermatitis (AD), we investigated the content-related quality of AD videos and their perception among YouTube users. METHODS: The quality of the 100 most viewed AD videos was assessed by using the Global Quality Scale (GQS) and the DISCERN instrument. Videos were classified as "useful," "misleading," and "potentially harmful," and the correlations of viewers' ratings (likes) with the GQS and DISCERN scores were assessed. RESULTS: Among the 100 videos, 68.0% (68/100) and 62.0% (62/100) were of poor and very poor scientific quality, respectively. Additionally, 32.0% (32/100) of the videos were classified as useful, 48.0% (48/100) were classified as misleading, and 34.0% (34/100) were classified as potentially harmful. Viewers' ratings did not correlate with the GQS and DISCERN scores. Overall, 50.0% (50/100) of the videos were posted by private individuals and promoters of complementary/alternative treatments, 42.0% (42/100) by therapeutical advertisers, and only 8.0% (8/100) by nonprofit organizations/universities. CONCLUSIONS: Our study demonstrated that two-thirds of the videos analyzed were below acceptable medical quality standards and that many videos were disseminating misleading or even dangerous content. Subjective and anecdotal content was overrepresented, and viewers did not appear to be able to distinguish between high- and low-quality videos. Health promotion strategies by professional medical organizations are needed to improve their presence and visibility on YouTube.

Analyzing Instagram Posts on Hypothyroidism: Characteristics, Information Types, Quality, and Reliability.

Background and aims In the age of social media, a vast amount of information is widely and easily accessible. Platforms such as Instagram allow its users to post pictures and videos that can reach millions of users. This could be utilized by healthcare providers to provide education to a vast number of the population about a disease such as hypothyroidism with an easily digestible infographic. However, this easy accessibility comes with the risk of rampant misinformation. This study aimed to evaluate the characteristics of Instagram posts, the type of information, and the quality and reliability of information posted about hypothyroidism. Methodology This is a cross-sectional observational study that was conducted over the course of days on Instagram. Top posts meeting inclusion criteria under seven different hypothyroidism-related hashtags were surveyed for content and social media metrics by the authors utilizing Google Forms. The quality and reliability of the posts were analyzed using the global quality scale and DISCERN scales, respectively. The data were exported to an Excel sheet and analyzed using the SPSS software version 21.0 (Armonk, NY: IBM Corp.). Results A total of 629 posts met the inclusion criteria of which 62.5% were images and 37.5% were reels. The content heavily focused on the medical aspect of hypothyroidism with posts about symptoms (46.1%), prevention (39.59%), cause/etiology (36.41%), and treatment (34.34%). The median DISCERN score which reflects the reliability of the posts uploaded was highest for doctors at 3 and the least reliable posts were uploaded by dieticians, naturopathic doctors, and patients. This study found that the quality of posts uploaded by nutritionists and naturopathic doctors with a median Global Quality Score (GQS) score of 3. Conclusions There is a need to establish a quality control body that regulates the quality and reliability of the posts to curb misinformation and help patients gain easy access to reliable resources that will aid their decision-making.

Temporomandibular disorders-related videos on YouTube are unreliable sources of medical information: A cross-sectional analysis of quality and content.

Objective: The amount of online medical information available is rapidly growing and YouTube is considered as the most popular source of healthcare information nowadays. However, no study has been conducted to comprehensively evaluate YouTube videos related to temporomandibular disorders (TMD). So this study aimed to evaluate the content and quality of YouTube videos as a source of medical information on TMD. Method: A total of 237 YouTube videos that were systematically searched using five keywords (temporomandibular disorders, tmd, temporomandibular joint, tmj, and jaw joint) were included. Included videos were categorized by purpose and source for analysis. The quality (DISCERN, Health on the Net (HON), Ensuring Quality Information for Patients (EQIP), and Global Quality Scale (GQS)) and scientific accuracy of video contents were evaluated. Results: Total content, DISCERN, HON, EQIP, and GQS scores were 7.5%, 38.9%, 35.2%, 53.0%, and 48.6% of the maximum possible score, respectively. Only 69 videos (29.1%) were considered as "useful" for patients. News media, physician, and medical source videos showed higher evaluation scores than others. Quality evaluation scores were not significantly correlated or negatively correlated with public preference indices. In the ROC curve analysis, content and DISCERN score showed above excellent discrimination ability for high-quality videos based on GQS (P < 0.001) and total score (P < 0.001). Conclusions: YouTube videos related to TMD contained low quality and scientifically inaccurate information that could negatively influence patients with TMD.

The quality and reliability analysis of YouTube videos about insulin resistance.

AIM: There is an increasing trend in the use of internet as a search tool for health-related informations. Insulin resistance is one of the most searched subjects online and some of the videos about insulin resistance have been watched by millions of YouTube users. This study aims to determine the quality and reliability of the most popular videos about insulin resistance on YouTube. METHODS: On March 1, 2022, the term "insulin resistance" was searched on YouTube. The videos' popularity was assessed with Video Power Index (VPI). The quality and reliability were assessed with DISCERN score, modified DISCERN score and global quality score (GQS). RESULTS: A total of 100 most popular videos were evaluated after applying the exclusion criteria. Fifty-four percent of the videos were very poor-poor, 35 % moderate, and 11 % good-excellent quality. Although few in number, the videos with relatively higher quality and more reliable had higher numbers of views, likes and comments (p < 0.01). There was a positive correlation between DISCERN score and VPI, duration, view, like, dislike, comment numbers of the videos (p < 0.01). Healthcare providers uploaded 58 % of the videos, while independent users uploaded 42 %. Video like ratio (VLR) at healthcare providers' videos was significantly higher than independent users' videos (p = 0.001). CONCLUSIONS: Despite the high viewing rates of YouTube videos about insulin resistance, the overall quality and reliability were found to be very low. However, when high quality content regarding popular medical topics is produced, more people can be informed correctly.

Assessment of the Quality and Reliability of YouTube Videos on Fuchs Endothelial Corneal Dystrophy.

Objectives: The aim of the study was to assess the quality and reliability of videos on Fuchs endothelial corneal dystrophy (FECD) on YouTube. Methods: A search of YouTube was performed for the term "FECD" without any changes to the website's standard search preferences. The first 100 videos were recorded. A total of 71 videos were evaluated regarding the DISCERN score (min-max: 16-75), Journal of the American Medical Association (JAMA) score (min-max: 0-4), and Global Quality Scale (GQS) score (min-max: 0-5). Results: The mean DISCERN score was 40.1±15.6 (moderate), the mean JAMA score was 2.01±0.7 (poor), the mean GQS score was 2.5±1.3 (moderate), and the mean video power index score was 106.8±135.7. Twenty-three of the videos (32.4%) were uploaded by physicians, 25 (35.2%) by universities/private hospitals, and 21 (29.6%) by health channels. Thirty-six videos (50.7%) contained information about the disease, 24 (33.8%) discussed surgical techniques, and 11 (15.5%) were about patient experience. Conclusion: YouTube provides only moderate-quality health information on FECD. Physicians and professional organizations should be aware of and embrace this evolving technology to raise awareness about FECD.
