Evaluation of the quality and content of YouTube videos as an educational resource in developing patients' inhaler use skills

BACKGROUND

YouTube has educational videos on inhalers. However, their content and quality are not adequately known.

OBJECTIVES

This study investigated the quality and content of educational YouTube videos on inhalers.

METHODS

This descriptive study analyzed 178 YouTube videos on inhalers between May and July 2022. Two researchers independently evaluated the videos. The Global Quality Score (GQS), Journal of American Medical Association (JAMA) Benchmark Criteria, and Inhaler Application Checklist (IAC) were used to assess the quality and content of the videos. Spearman's correlation, Kruskal-Wallis, Mann-Whitney U, ANOVA, and Post hoc analysis Bonferroni test were used for data analysis.

RESULTS

The videos had a mean GQS score of 3.70 ± 1.24, and JAMA score of 2.22 ± 0.60. A negative correlation was between the quality score of the videos and views, likes, comments, duration, and likes/views (respectively; r = -0.237 p < 0.005, r = -0.217 p < 0.003, r = -0.220 p < 0.005, r = -0.147, p < 0.005). The videos narrated by nurses and doctors had significantly higher mean JAMA and GQS scores than others (p = 0.001). The videos missed some procedural steps [gargling (29.1%), adding no more than five ml of medication and device cleaning (41.9%), and exhaling through the nose (37.5%)]. Videos uploaded by individual missed significantly more procedural steps than professional organizations (p < 0.05).

CONCLUSIONS

YouTube videos about inhaler techniques have a moderate level of quality. Videos uploaded by doctors and nurses as content narrators were of higher quality. The videos missed some procedural steps. Individual video uploaders had higher missed procedural steps. Counseling should be provided to patients regarding the reliability of online information.

Quality and reliability analysis of videos about ThuLEP on Youtube

OBJECTIVES

To assess the reliability and quality analyses of ThuLEP videos on YouTube, as a source of public information.

MATERIALS AND METHODS

In this study, a YouTube search with the keyword "ThuLEP" was performed on November 15, 2022 and 142 videos were listed according to relevance. Video features and source of upload were recorded. The quality of videos was evaluated by using both the Journal of American Medical Association (JAMA) score and the Global Quality Score(GQS); the reliability of videos was evaluated by using 5-point modified DISCERN tool,respectively. The correlation analysis was performed by using Spearman test between video features and these three scores.

RESULTS

77 videos were analysed after exclusion and the most common source of upload were urologists (54.5%) and the videos containing only ThuLEP surgery (74%) were the majority of the videos. The median JAMA score, 5-point modified DISCERN score, and GQS were 2, 1, 1, respectively. There were no statistical differences in these three scores according to the source of the upload. All three scores were analysed separately by language and no significant statistical difference was found.There was a positive correlation between the video power index and as well as JAMA, GQS and m. DISCERN scores.

CONCLUSIONS

Despite abundant videos on ThuLEP on YouTube, most of these videos are not targeted to public and information provided may not be as useful for patients. Information presented in these videos may be inaccurate and not reliable.

Pitfalls of social media for aesthetic eye surgery patients: assessing YouTube's aesthetic canthoplasty content

PURPOSE

YouTube, a popular source for diverse information, hosts a wealth of content on aesthetic canthoplasty. Yet, concerns linger about the accuracy and reliability of these videos, with potential for inaccuracies, biases, or misleading information. This study aims to evaluate the quality and reliability of YouTube content on this sought-after facial enhancement procedure.

METHODS

The study employs four distinct scoring tools: the Global Quality Score (GQS), the Medical Quality Video Evaluation Tool (MQ-VET), the Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-A/V), and the Video Power Index (VPI).

RESULTS

Analysis of a total of 173 YouTube videos relevant to aesthetic canthoplasty revealed scores that were primarily indicative of poor quality and reliability.(Mean score ± SD, PEMAT A/V: 30.75 ± 28.8, MQ-VET: 28.57 ± 12.6, GQS: 1.7 ± 1) Notably, these videos were predominantly uploaded by healthcare professionals (82.1%), and they focused more on advertisements (46.2%) than on scientific or educational information. Their elevated viewership and engagement metrics (likes, comments, and shares) attest to their significant popularity and influence. (Mean VPI score: 176.6 ± 635.8).

CONCLUSION

YouTube's influence on aesthetic eyelid surgery is undeniable, shaping patient choices and expectations. However, unrealistic beauty ideals, heightened body dissatisfaction, and social comparisons lurk within its content, potentially harming psychological well-being and surgical decisions. Prioritizing qualified medical guidance and critical evaluation of online information are crucial for patients. Authors and platforms must act responsibly: authors by producing high-quality content, platforms by tackling misinformation.

An Analysis of Dermatology-Related Red-Light Therapy Patient Questions on Reddit

BACKGROUND

Reddit is one of the world's most popular social media platforms and is increasingly used as a health information resource for patients on topics such as red-light (RL) therapy.

OBJECTIVE

In this article, the authors present an analysis of prevalent patient questions and concerns regarding RL therapy.

METHODS

All posts on the "Hot" page of the r/redlighttherapy subreddit were analyzed and categorized.

RESULTS

A total of 930 questions from 664 posts were analyzed. The most commonly asked question category was related to product recommendations or feedback (29.7%), followed by usage instructions (15.3%), safety and side effects (12.6%), and indications and efficacy (12.3%).

CONCLUSION

Understanding patient concerns and questions about RL, as expressed on online platforms like Reddit, can help clinicians improve patient satisfaction, education, and clinical outcomes. The study offers an innovative approach by using social media to uncover valuable patient insights that might not be easily observable within clinical settings.

Natural language processing of online support group postings reveals patients' perspectives on strategies for managing psoriasis

Psoriasis is a chronic skin disorder, and patients encounter high physical and psychosocial burdens. Social media forums feature extensive patient-generated comments. We hypothesized that analyzing patient-posted comments using natural language processing would provide insights into patient engagements, sentiments, concerns, and support, which are vital for the holistic management of psoriasis. We collected 32,000 active user comments posted on Reddit. We applied Latent Dirichlet Allocation to categorize posts into popular topics and employed spectral clustering to establish cohesive themes and word representation frequency within these topics. We sorted posts into 29 significant topics of discussion and categorized them into four categories: management (37.48%), emotion (21.57%), presentation (19.79%), and others (3.57%). The frequent posts on management were diet (7.23%), biologics (6.95%), and adverse effects (3.88%). The emotion category comprised negative sentiments (11.02%), encouragement (5.49%), and gratitude (5.06%). The presentation topic included a discussion of scalp (5.69%), flare-timing (3.63%), and arthritis (2.64%). Others comprised differential diagnosis (5.01%), leaky gut (4.12%), and referrals (3.70%). This study identified patients' experiences and perspectives associated with psoriasis, which should be considered to tailor support systems to improve their quality of life.

Online Depiction of Urticaria Is Often Flawed and Does Not Reflect the Spectrum of Clinical Manifestation

INTRODUCTION

The internet is a popular source of health information including images of disease manifestations. Online photographs of skin lesions may aid patients in identifying their disease, if these pictures are of good quality and of the disease they claim to show. If not, patients may be at risk of delayed diagnosis, misdiagnosis, and suboptimal treatment. For urticaria, the mismatch rate and quality of online pictures are unknown. The objective of this study was therefore to evaluate the content and quality of online images of urticaria.

METHODS

The search term "urticaria" was applied to Google Images and Shutterstock. The top 100 photographs from each search engine were retrieved on October 9th, 2022. Illustrations, drawings, and heavily edited photographs were excluded. Each image was evaluated for patient characteristics, characteristics of urticarial lesions, and image quality.

RESULTS

Across 194 unique images of urticaria (after removing duplicates), 35 (18.0%) did not depict urticarial lesions, and 38 (19.6%) were ambiguous. Less than two-thirds of images 121 (62.4%) showed bona fide urticarial lesions. Pictures of urticarial lesions under-represented children and did not reflect female preponderance of the disease. Images predominantly depicted urticaria lesions on Caucasian skin (59.8%) and were typical of spontaneous rather than inducible urticaria. Only 3 (1.5%) pictures showed angioedema, a common clinical sign in patients with urticaria. The overall quality of online urticaria pictures was mostly good or very good.

CONCLUSION

Physicians and patients should be aware that one in five online pictures of urticaria does not show urticarial skin lesions, and children, females, non-Caucasian patients, inducible urticaria, and angioedema are under-represented. These findings should prompt efforts to improve the accuracy and representativeness of online urticaria pictures.

YouTube® as a source of information for Spanish-speaking patients with rheumatoid arthritis

INTRODUCTION

Social media (SoMe) has reshaped access to health information, which may benefit patients with rheumatoid arthritis (RA), although an evaluation of the characteristics of contents for Spanish-speaking patients is lacking. We aimed to assess patient engagement, reliability, comprehensiveness, and quality of data uploaded to YouTube® for Spanish-speaking patients.

METHODS

We evaluated the videos uploaded to YouTube® in Spanish about RA. Information about video length, engagement (i.e., views, likes, popularity index), time online, and the source was retrieved; we appraised reliability (DISCERN), comprehensiveness (content score), and quality (Global Quality Score) using standardized scores.

RESULTS

We included 200 videos in the study and classified 67% of the videos as useful. These videos had a higher number of views (19,491 [10,132-61,162] vs. 11,208 [8183-20,538]), a longer time online (1156 [719-2254] vs. 832 [487-1708] days), and a shorter duration (6.3 [3.4-15.8] vs. 11.8 [7.4-20.3] min). Engagement parameters were similar between useful and misleading videos. Useful videos had higher reliability, comprehensiveness, and quality scores. Useful videos were mainly uploaded by independent users and government/news agencies; academic organizations offered only 15% of useful videos.

CONCLUSIONS

Most of the information in YouTube® for Spanish-speaking patients with RA is useful; however, patient engagement is similar between useful and misleading content. More substantial involvement of academia in developing high-quality educational multimedia is warranted.

Assessing the Educational Value of Pancreatic Cancer Videos on YouTube®

Online resources such as YouTube® can serve as the go-to resource for patients and their caregivers after a life-changing diagnosis of pancreatic cancer. There is a need to analyze the content and educational value of these videos for patients with pancreatic cancer. The top 100 most viewed videos on pancreatic cancer on YouTube® were assessed and data were collected on various variables such as views, likes, dislikes, and comments. Videos categorized as patient educational videos were further analyzed for their content, source, and educational value. Videos uploaded by patients were the most discussed (p = 0.014) and liked (p = 0.0028) videos on YouTube®. The content of the videos (personal experience, advertisement, patient education, medical professional education, alternative treatments, and increased pancreatic cancer awareness) varied depending on the uploader (patients, healthcare providers, professional societies, media) of the videos (p = 0.0007). Patient education videos were poor in being comprehensive on their education of pancreatic cancer based on our rubric (mean score of 7.67 ± 2.63 of 20 possible points). The current study shows that the educational values of YouTube® videos related to pancreatic cancer remain limited. There is significant room for healthcare providers to use the platform to develop and share comprehensive videos that can be used as more effective sources of patient education.

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.

Quality of healthcare information on YouTube: psoriatic arthritis

BACKGROUND

YouTube is an increasingly used platform for medical information. However, the validity of health-related information on psoriatic arthritis (PsA) on YouTube has not been determined.

OBJECTIVE

The purpose of this study was to evaluate the accuracy and quality of YouTube videos concerning PsA.

MATERIALS AND METHODS

A YouTube search was performed on April 18, 2021, using the keyword "psoriatic arthritis." Two independent raters accessed the content, source, and detailed characteristics of the included videos. The reliability and quality of the videos were analyzed using the modified DISCERN score, Journal of the American Medical Association benchmark criteria score, and global quality scale score.

RESULTS

Of the 200 videos screened, 155 were included in the study after applying the exclusion criteria. A total of 132 (85.2%) videos revealed useful information about PsA, whereas the remaining 23 (14.8%) were misleading. Video interaction parameters including the median number of views, views per day, likes, dislikes, and comments demonstrated no significant difference between the two groups. The videos posted by universities and professional organizations displayed the highest reliability and quality scores.

CONCLUSION

The majority of YouTube videos on PsA contained useful information. However, physicians should alert patients to the possibility of misinformation and non-validated sources. Professional organizations in the field of rheumatology, such as the American College of Rheumatology and European League Against Rheumatism, should consider collaborating with YouTube to deliver high-quality content.

Public Perception of SARS-CoV-2 Vaccines Among Psoriasis Patients in Social Media: Content, Sentiment, and Engagement Analysis

Background

Psoriasis patients may seek information about the SARS-CoV-2 vaccine and their disease from social media platforms. Analyses of social media interactions may help guide dermatologists' educational efforts during this pandemic.

Objectives

This study analyzes social media interactions among patients with psoriasis and psoriatic arthritis regarding the SARS-CoV-2 vaccine to determine the misinformation circulating and the apprehension to receiving the vaccine.

Methods

Publicly accessible Facebook and Reddit groups regarding psoriasis and psoriatic arthritis were identified. Posts uploaded between March 1, 2021 and July 31, 2021 which contained information about the SARS-CoV-2 vaccine were extracted. First-order themes, sub-themes, sentiment scores and engagement scores were assigned to each post.

Results

345 posts within the first-order theme of vaccination decision and 1379 posts within the first-order theme of vaccine reaction were analyzed. Within vaccination decision, common sub-themes for refusing the vaccine include fear of psoriasis flare up, vaccine is experimental, vaccine is unnecessary, vaccine is dangerous, and concern for reaction/vaccine efficacy while on psoriasis medications. 41.4% of posts contained positive sentiment; whereas, 38.3% contained negative sentiment. Within vaccine reaction, common sub-themes identified were no change to psoriasis, skin/joint flare up, skin flare up attributed specifically to stopping psoriasis medications, skin/joint improvement, and skin flare up but vaccine was worth it. 77.8% of posts contained positive sentiment; whereas, 6.2% contained negative sentiment.

Conclusions

Our study identified common SARS-CoV-2 vaccine concerns within the psoriasis community which should be used to guide educational efforts.

Is YouTube a reliable source of health-related information? A systematic review

BACKGROUND

YouTube is a valuable source of health-related educational material which can have a profound impact on people's behaviors and decisions. However, YouTube contains a wide variety of unverified content that may promote unhealthy behaviors and activities. We aim in this systematic review to provide insight into the published literature concerning the quality of health information and educational videos found on YouTube.

METHODS

We searched Google Scholar, Medline (through PubMed), EMBASE, Scopus, Direct Science, Web of Science, and ProQuest databases to find all papers on the analysis of medical and health-related content published in English up to August 2020. Based on eligibility criteria, 202 papers were included in our study. We reviewed every article and extracted relevant data such as the number of videos and assessors, the number and type of quality categories, and the recommendations made by the authors. The extracted data from the papers were aggregated using different methods to compile the results.

RESULTS

The total number of videos assessed in the selected articles is 22,300 (median = 94, interquartile range = 50.5-133). The videos were evaluated by one or multiple assessors (median = 2, interquartile range = 1-3). The video quality was assessed by scoring, categorization, or based on creators' bias. Researchers commonly employed scoring systems that are either standardized (e.g., GQS, DISCERN, and JAMA) or based upon the guidelines and recommendations of professional associations. Results from the aggregation of scoring or categorization data indicate that health-related content on YouTube is of average to below-average quality. The compiled results from bias-based classification show that only 32% of the videos appear neutral toward the health content. Furthermore, the majority of the studies confirmed either negative or no correlation between the quality and popularity of the assessed videos.

CONCLUSIONS

YouTube is not a reliable source of medical and health-related information. YouTube's popularity-driven metrics such as the number of views and likes should not be considered quality indicators. YouTube should improve its ranking and recommender system to promote higher-quality content. One way is to consider expert reviews of medical and health-related videos and to include their assessment data in the ranking algorithm.

Social media as source of information for Spanish-speaking patients with systemic lupus erythematosus

INTRODUCTION

Although patients with systemic lupus erythematosus (SLE) may benefit from health-care information in social media (SoMe), they may also be prone to misleading information. An assessment of the reliability, comprehensiveness, and quality of information uploaded to SoMe for Spanish-speaking patients with SLE is lacking.

METHODS

This analytical observational study evaluates the videos uploaded to YouTube^® in Spanish about SLE. Information about video length, engagement (i.e., views and likes), time on the internet, popularity index, and source was retrieved, and an evaluation on reliability, comprehensiveness, and quality was performed using standardized scores.

RESULTS

One hundred eighty-six videos were included in the analysis. Most videos were considered as useful (87%) or useful patient opinion (8.1%), whereas only 2.2% were considered misleading and 2.7% as misleading patient opinion. The number of views (Median 7207 vs 113,877, p = .012), popularity index (Median 13.8 vs 168.7, p < .001), number of likes (Median 155 vs 3400, p < .001), and number of dislikes (Median 3 vs 138, p = .004) were higher for misleading videos. The videos uploaded by independent users had a higher engagement than those from government or news agencies, professional organizations or academic channels. Misleading videos and those uploaded by independent users had lower rates of reliability, comprehensiveness and quality (p < .001).

CONCLUSIONS

Most of the information shown in YouTube^® videos on SLE tends to be useful. However, audience engagement parameters are larger for misleading videos. Exploring the qualitative features of the most popular videos is necessary to establish what features are more engaging for the audiences and to improve the content and popularity of reliable videos on chronic diseases.

Benefits, drawbacks, and challenges of social media use in dermatology: A systematic review

The presence of dermatological information on social media has grown exponentially over the last two decades. Consequently, the recent literature on this topic is abundant. Many authors have highlighted that social media constitutes a unique opportunity for patient education. Additionally, numerous other benefits of these platforms have been reported. However, other authors have focused on the potential risks that these networks involve. The main concerns are patient confidentiality, legal considerations and ethical issues. Therefore, we stand at a crossroads where the many advantages of social media use in dermatology seem to be underestimated due to the presence of potential drawbacks. At this point, we propose that a systematic review of the positive and negative aspects of using social media in dermatology is necessary. We carried out a comprehensive systematic review dating from inception to July 2021. Finally, 161 articles were included. Fifteen benefits, 11 drawbacks and 10 challenges of social media use in dermatology were identified and discussed. Suggested strategies to address the identified drawbacks were provided. Overall, while there are risks to using social media, they are outnumbered by their benefits. Therefore, dermatologists should embrace this opportunity to educate patients and aim to create rigorous and engaging content.

Patient and Public Involvement in Dermatology Research: A Review

Patient and public involvement (PPI) in research is defined as research being carried out 'with' or 'by' members of the public, patients, and carers, on both an individual and a group level, rather than simply 'about', or 'for' them. Within dermatology, PPI is increasingly recognised as a vital component of research as it helps to ensure that research remains relevant to the populations we intend to serve. Dermatology scholarship, with its rich psychosocial implications due to the stigma, physical disability, and mental health burdens these conditions may incur, is in a unique position to benefit from PPI to unlock previously inaccessible patient lived experiences or therapeutic consequences. Throughout the rapid growth of PPI, it has been infused throughout the research lifecycle, from design to dissemination and beyond. After first explaining the principles of PPI, we examine the existing evidence base at each research stage to explore whether our specialty has effectively harnessed this approach and to identify any subsequent impact of PPI. Finally, we scrutinise the challenges faced by those implementing PPI in dermatology research.

Social Media as a Medium for Dermatologic Education

Purpose of Review

We explore the utility of social media platforms as educational tools in dermatology, providing a summary of how these sites are used by the public and dermatologists alike, and demonstrating ways these findings may be applied for educational purposes.

Recent Findings

Over half of the world’s population utilizes social media platforms. More recently, these platforms have increasingly been used for educational purposes. In the field of dermatology, a large portion of the educational content is coming from users with no formal medical or dermatologic training.

Summary

Each of the top five social media platforms in the world (Twitter, Instagram, TikTok, YouTube, and Facebook) has unique qualities which people may utilize to educate fellow users. As more of the population seeks online health information and education, it is important that dermatologists, while taking ethical considerations into account, become more comfortable facilitating educational content on social media.

A qualitative analysis of online misinformation and conspiracy theories in psoriasis

Psoriasis is a chronic, hereditary disease with a complex immunopathogenesis, rendering it susceptible to misinformation. Misinformation related to psoriasis can have negative effects both on the public perception of psoriasis and on patients' knowledge of psoriasis. To characterize misinformation related to psoriasis available online, we performed a formal literature review via PubMed and a thematic review via Google. Key themes of misinformation included 'victim-blaming' (hygiene), 'vector' (contagion), 'vaccination', 'vilification' of conventional therapy, 'validation' of natural treatment and diet, 'veneration' of cures and 'vocalization' from celebrities. Misinformation related to psoriasis is pervasive on social media and other websites. Dermatologists, as patient advocates, should be aware of the content of misinformation available online and combat misleading health information to optimize health outcomes for patients with psoriasis.

YouTube as a source of information on breast cancer in the Arab world

BACKGROUND

The general population is increasingly using YouTube as a source of information on breast cancer, the most frequent cancer among women. Arabs are the most interested population in breast cancer on YouTube. The transmission of accurate information is important to reduce mortality rates. This cross-sectional study aims to evaluate breast cancer videos on YouTube in the Arab world.

METHODS

A YouTube search for "breast cancer" in Arabic was performed. The most viewed 60 videos included were evaluated for global quality (GQS score), reliability (modified DISCERN score), content (content score), and misleading claims. Recorded and calculated data included views, duration, videos power index, and viewers' interaction. Sources from legal persons (governments, universities, TV channels, physicians' groups), and blogs (online health channels, individuals) were categorized.

RESULTS

The median global quality (3/5), reliability (2/5), and content scores (4/11) were overall low. Misleading information was found in 42% of the videos. Although videos uploaded by legal persons were less popular (163,454 vs 327,488 views), they hosted more physicians (52% vs 15%), were less misleading (15% vs 64%), covered more content, and were of higher global quality and reliability than videos uploaded by blogs [p < 0.05]. While the topic of symptoms (55%) was discussed the most, genetic counseling (13%) and prevention (20%) were the least mentioned.

CONCLUSIONS

YouTube is poorly informational and inaccurate on breast cancer in the Arab World where it is highly used. Although videos uploaded by legal persons tend to be more adequate, they are of lower popularity. Governments and physicians are encouraged to upload more intelligibly informational videos, guide the population to reliable sources, and support regulations.

Systematic Literature Review on the Spread of Health-related Misinformation on Social Media

Contemporary commentators describe the current period as “an era of fake news” in which misinformation, generated intentionally or unintentionally, spreads rapidly. Although affecting all areas of life, it poses particular problems in the health arena, where it can delay or prevent effective care, in some cases threatening the lives of individuals. While examples of the rapid spread of misinformation date back to the earliest days of scientific medicine, the internet, by allowing instantaneous communication and powerful amplification has brought about a quantum change. In democracies where ideas compete in the marketplace for attention, accurate scientific information, which may be difficult to comprehend and even dull, is easily crowded out by sensationalized news. In order to uncover the current evidence and better understand the mechanism of misinformation spread, we report a systematic review of the nature and potential drivers of health-related misinformation. We searched PubMed, Cochrane, Web of Science, Scopus and Google databases to identify relevant methodological and empirical articles published between 2012 and 2018. A total of 57 articles were included for full-text analysis. Overall, we observe an increasing trend in published articles on health-related misinformation and the role of social media in its propagation. The most extensively studied topics involving misinformation relate to vaccination, Ebola and Zika Virus, although others, such as nutrition, cancer, fluoridation of water and smoking also featured. Studies adopted theoretical frameworks from psychology and network science, while co-citation analysis revealed potential for greater collaboration across fields. Most studies employed content analysis, social network analysis or experiments, drawing on disparate disciplinary paradigms. Future research should examine susceptibility of different sociodemographic groups to misinformation and understand the role of belief systems on the intention to spread misinformation. Further interdisciplinary research is also warranted to identify effective and tailored interventions to counter the spread of health-related misinformation online.

•

Studies on health misinformation mainly relate to vaccine and infectious disease.

•

Findings show high prevalence and popularity of misinformation on social media.

•

Theoretical frameworks are drawn on disparate disciplinary paradigms.

•

Studies employed content analysis, social network analysis or experiments.

•

More interdisciplinary research needed to understand the susceptibility of users.
