Quality and Reliability of YouTube Videos on Myocardial Infarction: A Cross-Sectional Study

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.

Assessment of YouTube Videos in Patient Education for Coronary Artery Disease: A DISCERN-Based Cross-Sectional Analysis

Introduction Cardiovascular disease has one of the highest mortality rates and continues to grow. Therefore, it is important for the medical community to get involved in widespread patient education efforts. As technology has steadily advanced, YouTube (Google LLC, Mountain View, California, United States) has become a popular source for patients to gather medical information. In this study, we aim to assess the quality of YouTube videos pertaining to coronary artery disease.  Methods We searched the following key terms on June 20, 2023, using the view count filter: coronary artery disease, coronary artery disease treatment, cardiac catheterization, and coronary artery bypass grafting (CABG). The top twenty videos for each keyword were recorded. After videos that were over 20 minutes, non-English, procedural videos without words, and duplicates were excluded, forty-five videos remained. Each video was assessed by three viewers using the DISCERN criteria (http://www.discern.org.uk). Numerical data was averaged into composite scores. Two-sided t-tests and one-way analysis of variance (ANOVA) tests were used to compare mean ratings between groups. A Spearman correlation was done to compare each of the following terms to one another: overall quality of videos, total likes a video received, and total views.  Results The mean ratings for coronary artery disease, coronary artery disease treatment, cardiac catheterization, and CABG were 2.30, 2.60, 2.05, and 2.92, respectively, with an overall mean of 2.42. The means between coronary artery disease and coronary artery disease treatment were significantly different (p adj = 0.01). The overall rating for videos with board-certified physicians was significantly higher than those without a board-certified physician (p < 0.001). There was a low correlation between likes and overall ratings (0.03) and views and overall ratings (-0.068). Conclusion The videos on coronary artery disease, coronary artery disease treatment, cardiac catheterization, and CABG had poor overall quality based on DISCERN criteria. The overall ratings from videos with board physicians are higher than those from non-physicians, suggesting that physicians should be encouraged to create content about important medical conditions. There was also a low correlation between the overall quality of a video and the likes and views, respectively, indicating a disconnect between what the public values and the actual value of a video.

Assessing the Quality and Reliability of Cardiac Rehabilitation Information on YouTube: A Systematic Evaluation

OBJECTIVES

This study aims to systematically evaluate the quality and reliability of YouTube videos on cardiac rehabilitation, addressing a gap in the literature regarding the assessment of online health resources in this field.

DESIGN AND SETTING

The study is a cross-sectional analysis. This research was conducted entirely online, utilizing the YouTube platform for data collection.

MAIN MEASURES

The videos were assessed for educational quality and reliability using modified versions of the DISCERN, Journal of the American Medical Association (JAMA), and Global Quality Scale (GQS) benchmarks. Specific data points such as upload date, length, uploader and narrator identity, and engagement metrics (views, likes, and dislikes) were also collected.

RESULTS

 Out of 300 videos initially reviewed, 140 met the inclusion criteria. The majority of videos were of low quality (67.9%), with medium (12.9%) and high-quality (19.3%) content being less common. Videos were predominantly uploaded by academic, university, or hospital sources (63.6%) and narrated by non-physician health professionals (41.4%). The content mainly provided general information about cardiac rehabilitation.

CONCLUSIONS

 The study revealed a concerning predominance of low-quality YouTube content on cardiac rehabilitation, underscoring the necessity for healthcare professionals and academic institutions to enhance the quality of online resources.

Assessment of the Quality and Reliability of Content Available on YouTube About Palpitations

Palpitations refer to the sensation of rapid, fluttering, or pounding heartbeats in the chest, the determinants of which may range from hormonal changes to anxiety or arrhythmias. YouTube is one of the most prevailing and accepted web-based platforms people trust to help them understand more about their health conditions. Thus, this study aims to assess whether the quality of content about palpitations on this platform is reliable and sufficient. Seventy-one YouTube videos were analyzed using criteria such as date and time of upload, type of uploader, and type of content. The Global Quality Score (GQS) and modified DISCERN score were used to analyze the quality and reliability of the information provided. Microsoft Excel (Microsoft Corporation, Redmond, WA, US) was used for data analysis, and StataCorp's 2023 Stata Statistical Software (College Station, TX, US) was used for statistical analysis and visualization. Of the 71 videos analyzed, 90.14% were uploaded more than a year ago, 80.28% described the symptomatology in detail, and 81.69% accurately described the etiological factors. Hospitals and doctors were the most common uploaders, constituting 23% and 19% of the uploaded videos, respectively, and had high GQSs (Median GQS = 4). The highest scores also belonged to videos uploaded by patients suffering from the disease (Median GQS = 5). Hospitals and news channels ranked highest on the reliability score (Median DISCERN = 4, respectively). It was determined that despite varied sources, the nature of content provided by the platform contains promotional material and content gaps; YouTube should, therefore, be used critically and as per professional sources.

YouTube as a Patient Information Source for Gastrointestinal Reflux Disease

Introduction Gastroesophageal reflux disease (GERD) affects a substantial portion of the global population, resulting in significant morbidity and impacting the quality of life. YouTube (YouTube, San Bruno, California) serves as a platform where medical professionals, individuals with personal experiences, and educational channels share their insights on GERD. However, with the vast amount of information available on YouTube, the question of credibility and reliability is a concern and, thus, is crucial to evaluate. This research paper aims to explore the impact of YouTube as a source of information on GERD. The aim of this study is to assess the quality and reliability of the information on YouTube about GERD. Methodology This cross-sectional observational study was conducted in June 2023. A questionnaire was designed using Google Forms (Google, Mountain View, California) with predetermined criteria such as characteristics of YouTube videos (time since uploaded, uploader, number of likes and comments); information about GERD (symptoms, investigations, treatment); and quality and reliability of information on YouTube about GERD using Global Quality Scale (GQS) and Reliability score. The Kruskal-Wallis Test was used to evaluate the difference in quality and reliability of information about GERD on YouTube based on the type of uploader.  Results Out of 90 videos analyzed, 68 YouTube videos on GERD that met inclusion criteria were included in the study. The number of videos uploaded by hospitals was 28 (41.2%), those by doctors was 12 (17.6%), and the remaining by others (like pharmacists, patients, and non-medical personnel) was 28 (41.2%). A significant proportion of videos (88.24%) shared information pertaining to disease symptoms and cause/etiology. The videos uploaded by "others" had significantly higher (p<0.05) reach as assessed by the Video Power Index (VPI) compared to those uploaded by doctors and hospitals. However, there was no significant difference (>0.05) in the quality and reliability of videos uploaded by doctors, hospitals, and other sources.  Conclusion Although the YouTube videos uploaded by doctors and hospitals had less reach among viewers compared to other uploaders (patients, news agencies, pharmaceutical companies, and others unrelated to healthcare), the quality and reliability of videos uploaded by doctors, hospitals, and other uploaders were of good quality and reliability and with no significant difference based on type of uploader. Healthcare organizations and government agencies should ensure that viewers have access to accurate and reliable information from social media like YouTube, which is crucial in their health decision-making.

Diabetes Mellitus on YouTube: A Cross-Sectional Observational Study to Assess the Quality and Reliability of Videos

Introduction Diabetes mellitus (DM) encompasses a group of heterogeneous, chronic, and non-communicable diseases characterized by an increase in blood glucose levels. As it has become easily accessible for patients to know about their symptoms and treatment of diseases, it is of utmost importance that reliable information is conveyed on the internet. If not managed appropriately, it may result in the dissemination of false information, leading to risky practices and incorrect treatment, further resulting in detrimental consequences. Aim To assess the quality and reliability of information related to DM on YouTube. Methodology A cross-sectional observational study was conducted in April 2023, wherein top YouTube videos related to 'diabetes' were analyzed for baseline characteristics, type of uploader, as well as quality and reliability using Global Quality Score (GQS) and Reliability Score (DISCEN), respectively. Statistical analysis was performed using SPSS software. Results A total of 87 videos were evaluated in the study. Unfortunately, only 21% of those were uploaded by doctors. The median Video Power Index (VPI) for videos uploaded by other sources was the highest (184.7), and the lowest was for videos uploaded by hospitals (12.6), and this was statistically significant (p = 0.038). The median GQS was highest for videos uploaded by doctors (4) and lowest for videos uploaded by others (3.5). The reliability score was higher in videos uploaded by healthcare organizations (4), which was not significant (p > 0.05). Conclusions Videos uploaded by physicians and healthcare organizations contained reliable information with a high global quality score. Videos uploaded by sources other than doctors and healthcare professionals should consult physicians, as self-diagnosis or self-treatment can lead to potential harm to patients.
