How artificial intelligence can provide information about subdural hematoma: Assessment of readability, reliability, and quality of ChatGPT, BARD, and perplexity responses.

Subdural hematoma is defined as blood collection in the subdural space between the dura mater and arachnoid. Subdural hematoma is a condition that neurosurgeons frequently encounter and has acute, subacute and chronic forms. The incidence in adults is reported to be 1.72-20.60/100.000 people annually. Our study aimed to evaluate the quality, reliability and readability of the answers to questions asked to ChatGPT, Bard, and perplexity about "Subdural Hematoma." In this observational and cross-sectional study, we asked ChatGPT, Bard, and perplexity to provide the 100 most frequently asked questions about "Subdural Hematoma" separately. Responses from both chatbots were analyzed separately for readability, quality, reliability and adequacy. When the median readability scores of ChatGPT, Bard, and perplexity answers were compared with the sixth-grade reading level, a statistically significant difference was observed in all formulas (P < .001). All 3 chatbot responses were found to be difficult to read. Bard responses were more readable than ChatGPT's (P < .001) and perplexity's (P < .001) responses for all scores evaluated. Although there were differences between the results of the evaluated calculators, perplexity's answers were determined to be more readable than ChatGPT's answers (P < .05). Bard answers were determined to have the best GQS scores (P < .001). Perplexity responses had the best Journal of American Medical Association and modified DISCERN scores (P < .001). ChatGPT, Bard, and perplexity's current capabilities are inadequate in terms of quality and readability of "Subdural Hematoma" related text content. The readability standard for patient education materials as determined by the American Medical Association, National Institutes of Health, and the United States Department of Health and Human Services is at or below grade 6. The readability levels of the responses of artificial intelligence applications such as ChatGPT, Bard, and perplexity are significantly higher than the recommended 6th grade level.

Assessing the educational value of laparoscopic radical nephrectomy videos on YouTube®: A comparative analysis of short versus long videos.

To evaluate the quality of laparoscopic radical nephrectomy videos and determine the extent to which they are informative and educational for healthcare professionals. We used the YouTube® search engine to search for the term 'laparoscopic radical nephrectomy' with time filters of 4-20 min (Group 1) and >20 min (Group 2) and then sorted the results uploaded chronologically before January 2023. One hundred videos were analysed for each group. The reliability of the videos was assessed using the Journal of American Medical Association (JAMA) Benchmark Criteria and DISCERN questionnaire scores (DISCERN). Educational quality was assessed using the Global Quality Score (GQS) and a 20-item objective scoring system (OSS) for laparoscopic nephrectomy. The popularity of the videos was evaluated using the video power index (VPI). The mean video duration was 8.9 ± 4.3 min in Group 1 and 52.02 ± 31.09 min in Group 2 (P < 0.001). The mean JAMA (2.49 ± 0.61) and OSS scores (60 ± 12.3) were higher in Group 2 than in Group 1, while no significant difference was observed in the mean GQS (2.53 ± 0.7, 2.39 ± 0.88, respectively) between the groups (P < 0.001, P = 0.039, P = 0.131, respectively). While the standardisation of surgical videos published on YouTube® and the establishment of auditing mechanisms do not seem plausible, high total OSS, periprocedural OSS, and VPI scores, and high OSS, JAMAS, GQS and DISCERN scores in long videos indicate that such videos offer a greater contribution to education.

Quality assessment of available Internet information on early orthodontic treatment

BackgroundThis study aimed to evaluate the content, reliability, quality and readability of information on Internet websites about early orthodontic treatment.MethodsThe “early orthodontic treatment” search term was individually entered into four web search engines. The content quality and reliability were reviewed with DISCERN, Journal of American Medical Association (JAMA), and Health on the Net code (HONcode) tools using the contents of websites meeting predetermined criteria. The readability of websites was evaluated with Flesch Reading Facilitate Score (FRES) and Flesch–Kincaid Grade Level (FKGL).ResultsEighty-six websites were suitable for inclusion and scoring of the 200 websites. 80.2% of websites belonged to orthodontists, 15.1% to multidisciplinary dental clinics and 4.7% to professional organizations. The mean DISCERN score of all websites (parts 1 and 2) was 27.98/75, ranging between 19 and 67. Professional organization websites had the highest scores for DISCERN criteria. Moreover, 45.3% of websites were compatible with JAMA’s disclosure criterion, 7% with the currency criterion, 5.8% with the authorship criterion and 5.8% with the attribution criterion. Only three websites met all JAMA criteria, and these websites belonged to professional organizations. None of the websites had the HONcode logo. Mean FRES and FKGL were 47.6 and 11.6, respectively.ConclusionsThe quality of web-based information about early orthodontic treatment is poor, and readability is insufficient. More accurate and higher quality Internet sources are required on the web.

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.

Assessing the Quality and Reliability of Rheumatoid Arthritis Exercise Videos on TikTok and YouTube

Objective: An autoimmune condition that frequently affects the synovial joints and other organ systems is called rheumatoid arthritis (RA). Social media platforms are increasingly used to access health-related information. The purpose of this study is to evaluate the RA exercise videos on YouTube and TikTok in terms of their accuracy, quality, and content-specificity. Methods: The term “rheumatoid arthritis exercise” was sorted on YouTube and TikTok on 25 July 2023. To simulate an average search query, the keyword by "top" results on TikTok and by "relevance" on YouTube were used. The Journal of American Medical Association (JAMA), DISCERN, and Global Quality Scale (GQS) scoring systems were used to evaluate the information's quality and accuracy. Additionally, the videos' attributes and sources were examined. Results: Fifty videos from each platform were included out of the 214 videos that were evaluated. YouTube videos had more views (35438 vs. 5989, p&lt;0.001), likes (871 vs. 199, p&lt;0.001), and uploads by doctors (34% vs.14%, p&lt;0.001) in addition to being longer (12.12 minutes vs. 0.42 minutes, p&lt;0.001). YouTube videos were also significantly more likely to receive high DISCERN reliability, quality and overall scores (21,5(11) vs. 15(6), 15(9) vs. 9(4) and 40,5(21) vs. 28(9), p&lt;0.001, respectively). In addition, YouTube videos had higher GQS scores and JAMA scores (24% vs. 4%, 2(1) vs. 1(1), p&lt;0.001, respectively). Conclusion: RA exercise related videos are more likely to have higher quality and accuracy on YouTube than on TikTok. It is important to provide videos by healthcare professionals to guide patients about accurate and high-quality health-related information.

Quality of YouTube Videos Regarding Anterior Cruciate Ligament Reconstruction Using Quadriceps Tendon Autograft Is Unsatisfactory

PurposeThis study aimed to assess the validity and informational value of teaching material regarding anterior cruciate ligament reconstruction (ACL-R) using quadriceps tendon (QT) autograft provided on the YouTubeTM video platform. MethodsAn extensive systematic search of the YouTubeTM video platform was performed, and all videos that met the criteria were included in the analysis. The analysis of the video content was performed using the DISCERN instrument, Journal of American Medical Association (JAMA) benchmark criteria and Global Quality Score (GQS). The duration of the videos, the date of publication, and the number of likes and views were recorded. Furthermore, videos were categorized based on the source (physicians, companies, patients), the subject (surgical technique, patient experience and overview [overview videos were videos in which multiple aspects were analyzed]) and the type of content (educational or subjective patient experience). ResultsA total of 88 videos were included in the analysis. Seventy-one (80.7%) videos were published by physicians, 15 (17.0%) by patients and 2 (2.3%) by companies. The majority of the videos described various surgical techniques (59 – 67.0%), 80.7% of the videos (72 – 81.8%) had an educational nature, and the remaining 18.2% described patient experiences. The mean length of the videos was 8.21 ±7.88 minutes. The mean number of views was 3988.51 ±9792.98 (range: 9-56047), while the mean numbers of comments and likes were 30.07±70.07 (range: 0-493) and 4.48 ±14.22 (range: 0-82), respectively. The mean DISCERN score, JAMA score, and GQS were 27.43 ±11.56 (95% CI: 25.01–29.85; range: 17-68), 1.22 ±0.85 (95% CI: 1.04–1.40; range: 0-3), and 1.82 ±0.93 (95% CI: 1.63–2.01; range: 1-4), respectively. For all scores, videos published by physicians had higher quality (DISCERN score, JAMA score, and GQS) (p<0.05). Among all of the analyzed videos, overview videos were of the highest quality (p<0.05). ConclusionsYouTube™ is a fast and open-access source of mass information. The overall quality of the videos on ACL reconstruction performed using QT autograft was unsatisfactory, demonstrating low educational quality and reliability. Currently, YouTube™ cannot be recommended as a reliable source of information on ACL reconstruction with the quadriceps tendon.

Youtube as a source of information about stroke rehabilitation during the COVID-19 pandemic

Objective: Although stroke rehabilitation (SR) is part of post-stroke recovery, patients have limited knowledge on this subject. This study aims to analyze YouTube videos about SR in terms of the information value and quality. Methods: On YouTube.com; the word “SR” was searched in September 6th, 2021. The listed first 100 videos were classified according to count of like, dislike, source of upload, origin of country and contents of SR. Quality, reliability and accuracy of the videos were determined with Global Quality Score (GQS), Journal of American Medical Association (JAMA) benchmark criteria and Modified DISCERN questionnaire, respectively. Results: According to the results of the study, 59 low quality, 28 medium quality, and 13 high-quality videos were determined. Eighty one percent of the videos contained insufficient data. Academic and physician-sourced videos comprised the majority (84.7%) of the high-quality group. A statistically significant result was found between the video sources and the number of views, likes, dislikes, comments, and video duration (p&lt;0.05). A weak positive correlation was found between video durations and GQS (r=0.671), JAMA benchmark criteria (r=0.665), modified DISCERN (r=0.701) scores (p&lt;0.001). Conclusion: Our results showed that most of the YouTube videos on SR have poor quality and insufficient data. High-quality videos have a longer duration and are uploaded by academic and physician video sources. YouTube can be considered an alternative resource besides tele rehabilitation for patients who need SR and whose health care was interrupted during the COVID pandemic. It can be said that higher-quality videos created by health professionals will be more useful for patient education in future.

Comparison of Educational and Academic Quality of Laparoscopic Distal Pancreatectomy Videos on WebSurg® and YouTube® Platforms.

The aim of this study was to compare the educational and academic quality of laparoscopic distal pancreatectomy (LDP) videos on YouTube® and WebSurg® platforms. YouTube and WebSurg platforms were searched with the keyword "laparoscopic distal pancreatectomy". According to the exclusion criteria, 12 videos were found on WebSurg. To ensure a 1:1 ratio, the first 12 videos that met the criteria on YouTube were also analyzed. Journal of American Medical Association (JAMA) benchmark criteria were used to evaluate the reliability of the videos. The non-educational quality of the videos was calculated using the Global Quality Score (GQS), the educational and academic quality of videos was calculated using Laparoscopic Distal Pancreatectomy-specific score (LDP-SS) and Laparoscopic Surgery Video Educational Guidelines scoring system (LAP-VEGaS). The mean JAMA score was 1.58 on YouTube and 2.83 on WebSurg (P < .001). The median GQS was 2 on YouTube and 5 on WebSurg (P < .001). The median LAP-VEGaS score was 8 on YouTube and 14.5 on WebSurg (P < .001). The median LDP-SS score was 6 on YouTube and 9.5 on WebSurg (P = .001). According to the LAP-VEGaS, eleven (91.7%) of the WebSurg videos had a high score of 11 or more (P = .04). According to Spearman correlation analysis, there was a statistically significant positive correlation between LDP-SS and JAMA, GQS and LAP-VEGaS (r: .589, P = .002; r: .648, P = .001; r: .848, P < .001 respectively). The WebSurg is superior to the YouTube in terms of educational and academic value, quality, accuracy, reliability and usability in scientific meetings for LDP videos.

Can YouTube be used as a source of information for swallowing disorders in individuals with dementia?

Objectives: This study aimed to examine YouTube video content as a general source of information about dysphagia in individuals with dementia. Materials and Methods: In this study, videos about dysphagia in individuals with dementia uploaded to the YouTube platform on June 4, 2023, were analyzed using the keywords “swallowing in dementia,” “swallowing disorders in dementia,” and “dysphagia in dementia.” Modified DISCERN was used to assess the reliability of the videos, the Global Quality Scale to assess their quality, the Journal of American Medical Association (JAMA) benchmark criteria to assess their transparency, and the Video Power Index to calculate their popularity. Twenty-four videos uploaded between October 21, 2009, and October 31, 2022 were included in the final content analysis. Results: Speech and language therapists/pathologists (SLPs) uploaded 54.17% of the videos, 37.50% were uploaded by non-SLP health workers, and 8.33% were uploaded by other individuals. Global Quality Scale scores were positively correlated with JAMA and video duration and negatively correlated with the number of days elapsed. There was a statistically significant difference in the duration, number of views, number of likes, comments, and JAMA mean scores among video sources (SLP vs. non-SLP health workers; p&lt;0.05). Conclusion: The number of videos about swallowing and swallowing disorders in individuals with dementia on YouTube is low; popularity does not reflect high quality, reliability, or competence. Therefore, health professionals working in this field, such as speech-language pathologists, neurologists, and otolaryngologists, should increase the number of informative and guiding videos and ensure that videos that are considered accurate are communicated to the patient and caregiver/relative.

Assessment of Arabic Web-Based Knowledge About Clear Aligners: An Infodemiologic Study.

Orthodontic treatments aim to enhance dental aesthetics, functionality, and long-term oral health. Clear aligners have gained popularity as an aesthetic and convenient option for patients seeking orthodontic correction. However, the quality and readability of online Arabic patient-centered information regarding clear aligners has not been studied yet. The aim of our study is to investigate the quality and readability of Arabic patient-centered information about clear aligners. We conducted an extensive evaluation of Arabic web-based content pertaining to clear aligners using three prominent search engines. Eligible websites were categorized based on specialization, organizational affiliation, material type, and presentation style. We assessed website quality and reliability using the DISCERN instrument, Journal of American Medical Association (JAMA)benchmarks, and Health on the Net (HON) code. In addition, we measured readability using the Flesch Reading Ease Score (FRES), Simplified Measure of Gobbledygook (SMOG), and Flesch-Kincaid Grade Level (FKGL). Out of 600 search results, 195 websites met the inclusion criteria. None of the websites were HON-code accredited. DISCERN assessments revealed low content quality, with none of the websites achieving high-quality status. The JAMA benchmarks showed limited compliance with the four items, with currency being the most frequently achieved. Readability assessments indicated generally high readability, with FKGL scores suggesting easy comprehension for the average readers. While Arabic web-based information on clear aligners is highly readable, its credibility and quality require significant improvement. Websites should adhere to medical information standards, subject content to rigorous assessments, and seek accreditation to ensure reliability. Enhancing the accessibility and comprehensibility of health-related content will empower individuals to make informed health decisions. Addressing limitations, such as social media and video content evaluation, and conducting comparisons with English websites in future research will provide a more comprehensive understanding of the landscape of online orthodontic information.

Quality, reliability, and content assessment of YouTube™ videos associated with aphasia

Aims: Health-related videos on YouTube make it easy to share information on diseases and address a wide audience. However, there is doubt among specialists about their reliability, quality, and whether they contain correct information. The present study aimed to evaluate the quality of the information provided by searching for “aphasia” on YouTube™.&#x0D; Methods: The results of the YouTube™ search were examined using the keywords “aphasia, Broca, Wernicke, conductive type, transcortical, anomic”. A total of 100 videos were identified, containing at least one of the keywords, relevant to the context, having at least 1000 views, published after 2010, in the English language, and shorter than 60 minutes. Modified DISCERN, Global Quality Score (GQS), Video Information and Quality Index (VIQI), and the Journal of American Medical Association (JAMA), rating, viewer interaction, and meta data were used for evaluating the videos. The scores of the scales indicated by The Kruskal-Wallis H Test were compared between the groups according to the video source (news agency, healthcare personnel/specialist, other people). The data were analyzed with Dunn’s Test as a post-hoc test. Relational analyses and Spearman’s RHO Correlation were used for statistical analyzes. The significance level was taken as p

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

BackgroundGiven a prolonged course of Cervical spondylosis (CS) could cause irreversible neurological deficits, it is crucial to disseminate CS-related health information to the public to promote early diagnosis and treatment. YouTube has been widely used to search for medical information. However, the reliability and quality of videos on YouTube vary greatly. Thus, this study aimed to assess the reliability and educational quality of YouTube videos concerning CS and further explore strategies for optimization of patient education.MethodsWe searched YouTube online library for the keywords “cervical spondylosis”, “cervical radiculopathy” and “cervical myelopathy” on January 15, 2023. Ranked by “relevance”, the first 50 videos of each string were recorded. After exclusions, a total of 108 videos were included. All videos were extracted for characteristics and classified based on different sources or contents. Two raters independently evaluated the videos using Journal of American Medical Association (JAMA) benchmark criteria, Modified DISCERN (mDISCERN) tool, Global Quality Scale (GQS) and Cervical-Spondylosis-Specific Scale (CSSS), followed by statistical analyses. All continuous data were described as median (interquartile range).ResultsAll videos had median values for JAMA, mDISCERN, GQS and CSSS scores of were 3.00 (1.00), 3.00 (2.00), 2.00 (1.00) and 7.00 (8.88), respectively. There were significant differences in VPI (P = 0.009) and JAMA (P = 0.001), mDISCERN (P < 0.001), GQS (P < 0.001) and CSSS (P < 0.001) scores among different sources. Videos from academic source had advantages in reliability and quality scores than other sources. VPI (P < 0.001), mDISCERN (P = 0.001), GQS (P < 0.001) and CSSS (P = 0.001) scores also significantly differed among videos of various contents. Spearman correlation analysis indicated VPI was not correlated with either reliability or quality. Multiple linear regression analysis showed a longer duration and an academic source were independent predictors of higher reliability and quality, while a clinical source also led to the higher video quality.ConclusionsThe reliability and educational quality of current CS-related videos on YouTube are unsatisfactory. Users face a high risk of encountering inaccurate and misleading information when searching for CS on YouTube. Longer duration, source of academic or clinician were closely correlated to higher video reliability and quality. Improving the holistic reliability and quality of online information requires the concerted effort from multiple parties, including uploaders, the platform and viewers.

Notably, videos depicting patient experiences had distinct characteristics and higher evaluation scores, emphasizing their significance within the study. Conclusion This study assessed YouTube videos related to bariatric surgery within the realm of medical tourism. The research illuminated diverse facets of medical tourism concerning obesity surgery and the quality of information disseminated on YouTube. Although patient experience videos received higher quality ratings, the overall reliability and content diversity underscored the potential and challenges of utilizing YouTube as an information source for medical tourism.

Are YouTube videos claiming to describe lumbar spinal manipulation techniques adequate?

ABSTRACT Background and objective YouTube has become a digital visual library in almost all fields of life, including medicine. Healthcare professionals and students frequently use YouTube to gain new skills and knowledge; however, the content of these videos has not been scientifically evaluated. Therefore, this study aimed to determine the descriptive adequacy and quality of YouTube videos on lumbar spine manipulation techniques (LSMTs) prepared by different healthcare professionals. Methods The first 50 most relevant videos retrieved on searching YouTube for the keyword ‘lumbar spinal manipulation techniques’ were included in the study. The video metrics (total duration, number of views, time since upload, number of comments, number of likes, and number of dislikes) that could be accessed from video descriptions were recorded. However the videos were scored according to manipulation definition criteria proposed by the American Academy of Orthopedic Manual Physical Therapists (AAOMPT manipulation description score – AAOMPT-MDS) and benchmark criteria for quality of digital content by the Journal of American Medical Association’s (JAMA). The video metrics, AAOMPT-MDS and JAMA scores of the videos prepared by medical doctors, chiropractors, osteopaths, and physiotherapists were compared. Results Video metrics of groups were similar. The mean AAOMPT-MDS of the videos was 2.40 ± 1.57 out of 6.00 (higher score was better), and the mean JAMA score was 2.14 ± 1.05 out of 4.00 (higher score was better). Videos created by all professional groups had statistically comparable AAOMPT-MDS and JAMA scores (p > 0.05). Conclusion Although YouTube videos on LSMTs offer valuable information for professionals and students, creators should follow the proposed recommendations when producing these videos to ensure quality content and systematic presentation.

The search was limited to the first 100 videos. Modified DISCERN, Global Quality Score (GQS), Video Information and Quality Index (VIQI), and the Journal of American Medical Association (JAMA) criteria were used for the evaluation of the videos. The Kruskal-Wallis H Test, Mann-Whitney U, and Spearman's RHO correlation were used for statistical analyses. The significance level was taken as p

Evaluation of the reliability and quality of YouTube videos as a source of information for transcutaneous electrical nerve stimulation.

YouTube plays an influential role in disseminating health-related information in the digital age. This study aimed to evaluate YouTube videos on transcutaneous electrical nerve stimulation (TENS) in terms of their information value and quality. In this descriptive study, we ranked the first 100 videos that met the inclusion criteria using the search term "transcutaneous electrical nerve stimulation" on October 30, 2022. These videos were classified according to the number of views, likes, dislikes, comments, duration, popularity and content categories. Reliability, quality, and accuracy of the videos were assessed using the Journal of American Medical Association (JAMA) Benchmark Criteria and Modified DISCERN Questionnaire and Global Quality Score (GQS). Video popularity were calculated by the Video Power Index (VPI). Based on the GQS results, we found that 59, 27, and 14 videos had low, intermediate, and high quality, respectively. In addition, based on the JAMA results, 79 and 21 videos had poor and high reliability, respectively. No statistically significant difference was found between the JAMA, modified DISCERN and GQS scores in terms of the sources of videos (p=0.226, p=0.115, p=0.812). Notably, there was a weak positive correlation between the JAMA scores and the number of views (r=0.204, p=0.041). According to our study results, most YouTube videos on TENS were of low quality and reliability. Additionally, most videos were uploaded from sources created by doctors; the most frequently found content was about the TENS procedure, and content on complications of the procedure became less frequent as the videos became more recent. In particular, it was found that videos uploaded by academics have longer duration. It has been found that reliable videos with high JAMA scores also have high number of views. Accordingly, it can be concluded that videos with higher quality and more reliability that are created by healthcare providers will be more useful for patients seeking information about TENS.

TikTok and Bilibili as sources of information on Helicobacter pylori in China: A content and quality analysis.

Helicobacter pylori (H. pylori) is closely associated with gastric diseases and has a high prevalence in China. Public platforms are considered common and important tools to publicize H. pylori-related information. This study aimed to assess and compare the content and quality of H. pylori-related videos on TikTok and Bilibili. A search was performed on the TikTok and Bilibili platforms using the keyword "H. pylori". The source of upload was categorized as for-profit organizations, general users, health professionals, news agencies, nonprofit organizations, and science communicators. The Journal of American Medical Association (JAMA), Global Quality Scale (GQS), and modified DISCERN scores were used to evaluate the quality of the included videos. A total of 93 TikTok videos and 79 Bilibili videos were included and analyzed. TikTok videos had a significantly shorter duration than Bilibili videos (64 vs. 149 s, respectively; p < 0.001). The duration of the video showed a positive correlation with the modified DISCERN and GQS scores (p < 0.001, r = 0.388 and r = 0.437, respectively). The JAMA and modified DISCERN scores of the TikTok video were significantly higher in health professionals and nonprofit organizations than in other sources (p < 0.05). For Bilibili, science communicators had a significantly higher JAMA score than the other video sources (p < 0.001). The videos uploaded by news agencies received more views, comments, shares, and favorites than any other organization or individual (p < 0.001). In China, H. pylori-related videos from TikTok and Bilibili tended to provide the information regarding the transmission and eradication of H. pylori. However, many videos scored an average rating in content and quality and need to be improved. We recommend that the public obtain H. pylori-related information through videos uploaded by health professionals, nonprofit organizations, and science communicators.

Online information on chronic pain in 3 countries: an assessment of readability, credibility, and accuracy.

To assess the readability, credibility, and accuracy of online information on chronic pain in Australia, Mexico, and Nepal. We assessed Google-based websites and government health websites about chronic pain for readability (using the Flesch Kincaid Readability Ease tool), credibility (using the Journal of American Medical Association [JAMA] benchmark criteria and Health on the Net Code [HONcode]), and accuracy (using 3 core concepts of pain science education: (1) pain does not mean my body is damaged; (2) thoughts, emotions, and experiences affect pain; and (3) I can retrain my overactive pain system). We assessed 71 Google-based websites and 15 government websites. There were no significant between-country differences in chronic pain information retrieved through Google for readability, credibility, or accuracy. Based on readability scores, the websites were "fairly difficult to read," suitable for ages 15 to 17 years or grades 10 to 12 years. For credibility, less than 30% of all websites met the full JAMA criteria, and more than 60% were not HONcode certified. For accuracy, all 3 core concepts were present in less than 30% of websites. Moreover, we found that the Australian government websites have low readability but are credible, and the majority provided all 3 core concepts in pain science education. A single Mexican government website had low readability without any core concepts but was credible. The readability, credibility, and accuracy of online information on chronic pain should be improved internationally to support facilitating better management of chronic pain.

Quality, Understandability and Reliability of YouTube Videos on Skin Cancer Screening

In 2008, a nationwide skin cancer screening (SCS) program was implemented in Germany. However, participation rates remain low. YouTube videos on SCS might educate eligible persons to undergo SCS. Until now, no scientific evaluation of the quality of videos available for German-speaking persons eligible for SCS has been performed. Here, we identified and evaluated videos on SCS provided on YouTube. YouTube was searched in May 2022 for German terms related to SCS. Two authors evaluated the videos of the first three pages that met the predefined eligibility criteria. The quality of the videos´ information was evaluated using DISCERN and the Global Quality Scale (GQS). The understandability and actionability were assessed with the Patient Education Materials Assessment Tool (PEMAT). The reliability was assessed with the Journal of American Medical Association (JAMA) score. Subgroup differences were identified by the Kruskal–Wallis test. Overall, 38 videos were included in the evaluation. Most videos were provided by health professionals (clinics and practices). The average scores (mean (SD)) for the individual tools were as follows: DISCERN 3.1/5 points (± 0.52), GQS 3.72/5 points (± 0.7), understandability 64,27% (± 13.53%), actionability 58.22% (± 15.18%), JAMA 37.17% (± 18.94%). These results indicate a mediocre to good understandability, a mediocre quality and actionability, and a low reliability. Videos that were assessed as useful were of significantly better quality. An improvement of freely available informational videos on SCS, especially with regard to the reliability criteria, is urgently needed.
