      PURPOSE: Current methodologies for designing search strategies rely heavily on the knowledge and expertise of information specialists. Yet, the volume and complexity of scientific literature is overwhelming for even the most experienced information specialists, making it difficult to produce robust search strategies for complex systematic reviews. In this case study, we aimed to assess and describe the benefits and limitations of using semi-automated text-mining tools for designing search strategies in a systematic review of diagnostic test accuracy.METHODS: An experienced information specialist designed a search strategy using traditional methods. This strategy was then amended to include additional terms identified by text-mining tools. We evaluated the usability and expertise required, risk of introducing bias to the search, precision of the search strategy and rated the usefulness of the tools.
    RESULTS: Thirteen of the 16 investigated tools produced a total of 40 additional terms, beyond those in the original search strategy. This resulted in 11 previously unidentified relevant articles being retrieved. Precision was reduced or remained the same in all cases. After considering all aspects of the investigation we rated each application, with two being 'extremely useful', three being 'useful', three having 'no impact' and eight being 'not very useful'. Comparative analysis revealed discrepancies between similar tools.
    CONCLUSIONS: Our findings have implications for the way in which these methodologies are used and applied to search strategies. If semi-automated techniques are to become mainstream in information retrieval for complex systematic reviews, we need tailored tools that fit information specialists' requirements across disciplines.

      The UK Government Web Archive (UKGWA) has been archiving government websites since 1996 and now holds regular snapshots of over 5000 sites. Currently, this material can be accessed through browsing or a simple keyword search interface on their website and has also been catalogued in The National Archives' online catalogue, Discovery. However, the scale of the UKGWA exposes the limits of the current search interface, and there is no facility to understand the archive in aggregate. This article seeks to go beyond the simple keyword search by exploring the data sources available, from APIs to web crawling, for computational analysis of the UKGWA. The article is accompanied by two Python Notebooks which present examples of analysis using each data source. Notebooks lower the technical barriers for the reader to explore and interpret the UKGWA as data, while surfacing the challenges around making web material computationally accessible.

      BACKGROUND: The COVID-19 pandemic has caused not only a disease epidemic but also an infodemic. Due to the increased use of the Internet and social media, along with the development of communication technology, information has spread faster and farther during the COVID-19 infodemic. Moreover, the increased choice of information sources has made it more difficult to make sound decisions regarding information. Although social media is the most common source of misinformation, it can also be spread through other forms of media. However, the media sources used by people with high health literacy and COVID-19 knowledge to obtain information is unclear. Furthermore, the association between the use of multiple information sources and health literacy or COVID-19 knowledge is ill-defined.OBJECTIVE: This study aimed to examine the following three aspects regarding COVID-19 infodemic: (1) the relationship between health literacy, COVID-19 knowledge, and the number of information sources used; (2) the impact of media use on health literacy; (3) the impact of media use on COVID-19 knowledge.
    METHODS: An online cross-sectional study was conducted in November 2021. Participants were 477 individuals aged 20-69 years. After obtaining consent to participate in the study, participants were asked about sociodemographic indicators, sources of health-related information, health literacy, and COVID-19 knowledge. Sources of health-related information were categorized into four types: mass media, digital media, social media, and face-to-face communication. Spearman's rank correlation test was conducted to determine the relationship between health literacy, number of correct answers to COVID-19 knowledge, and number of information sources used. Multiple regression analysis was conducted with health literacy and the number of correct answers as dependent variables, the four media types as independent variables, and age and gender as adjustment variables.
    RESULTS: Mass media was the most frequently used source of information, followed by digital media, face-to-face communications, and social media. Social media use was significantly higher among individuals aged 20-29 years than among other age groups. Significant positive correlations were found between health literacy, number of positive responses to COVID-19 knowledge, and number of information sources used. Multiple linear regression analysis showed that health literacy was associated with access to information from digital media and face-to-face communication. Additionally, COVID-19 knowledge was associated with access to information from mass media, digital media, and face-to-face communication.
    CONCLUSIONS: Health literacy and COVID-19 knowledge could be improved using diverse information sources, especially by providing opportunities to use digital media and face-to-face communication. Furthermore, it may be important to improve health literacy and provide accurate knowledge about COVID-19 to young adults.

      In 2010, our editorial team wrote about the Internet's inarguable role in overloading information on our readers. In this editorial, we reflect on insights gained, mostly in the past decade, regarding the Internet and social media. Medical and surgical information online is easy to obtain, but it varies from platform to platform, is low in quality and reliability, and overestimates the public's ability to decipher the information. Physicians do not use social media enough, or well. Social media can engage patients and can inform patients about the quality of medical and surgical information online. Physicians, themselves, can provide reliable information that informs patients and eases their minds. Physician-authors can use social media to develop communities with shared interests in research; members of these communities can post research findings and highlight the publications in which they find them. Discussion of research online increases the likelihood that it will be cited. It is no surprise that the Internet and social media have contributed to the growth of Arthroscopy; Arthroscopy Techniques; and Arthroscopy, Sports Medicine, and Rehabilitation.

      STUDY DESIGN: Cross-sectional analysis of patient educational materials from top pediatric orthopedic hospital websites.OBJECTIVE: To assess the readability of online educational materials of top pediatric orthopedic hospital websites for pediatric spinal deformity. The internet has become an increasingly popular source of health information for patients and their families. Healthcare experts recommend that the readability of online education materials be at or below a 6th-grade reading level. However, previous studies have demonstrated that the readability of online education materials on various orthopedic topics is too advanced for the average patient. To date, the readability of online education materials for pediatric spinal deformity has not been analyzed.
    METHODS: Online patient education materials from the top 25 pediatric orthopedic institutions, as ranked by the U.S. News and World Report hospitals for pediatric orthopedics, were accessed utilizing the following readability assessments: Flesch-Kincaid (FK), Flesch Reading Ease, Gunning Fog Index, Coleman-Liau Index, Simple Measure of the Gobbledygook Index (SMOG), Automated Readability Index, FORCAST, and the New Dale and Chall Readability. Correlations between academic institutional ranking, geographic location, and the use of concomitant multi-media modalities with FK scores were evaluated using a Spearman regression.
    RESULTS: Only 48% (12 of 25) of top pediatric orthopedic hospitals provided online information regarding pediatric spinal deformity at or below a 6th-grade reading level. The mean FK score was 9.0 ± 2.7, Flesch Reading Ease 50.8 ± 15.6, Gunning Fog Score 10.6 ± 3.1, Coleman-Liau Index 11.6 ± 2.6, SMOG index 11.7 ± 2.0, Automated Readability Index 8.6 ± 2.8, and Dale-Chall Readability Score 6.4 ± 1.4. There was no significant correlation between institutional ranking, geographic location, or use of multimedia with FK scores.
    CONCLUSION: Online educational material for pediatric spinal deformity from top pediatric orthopedic institutional websites are associated with poor readability.

      BACKGROUND: There is a growing literature on the potential medical uses of Cannabis sativa and cannabinoid compounds. Although these have only been approved by regulatory agencies for a few indications, there is a hype about their possible benefits in a variety of conditions and a large market in the wellness industry. As in many cases patients search for information on cannabis products online, we have analyzed the information on medical cannabis available on the Internet. Therefore, this study aims at assessing the quality of the information available online on medical cannabis.METHODS: We searched "medical cannabis" on June 2019 using and downloaded the first 243 websites. After excluding dead links or websites with no information about cannabis, 176 websites were included. They were then classified for their typology (e.g., commercial, government, news outlets). As an indicator of trustworthiness, we used the Journal of American Medical Association (JAMA) score, which assesses the indication of date, author, ownership of the website, and the presence of references. We also considered if a website is certified by Health-On-the-Net (HON), an independent organization, by displaying a HONCode symbol. Subsequently, we performed a content analysis to assess both the medical cannabis indications mentioned by webpages and the completeness of the information provided (whether they mentioned potential side effects and legal/regulatory issues or not).
    RESULTS: Analyzing 176 webpages returned by a search engine, we found that 52% of them were news websites. Pain, epilepsy, and multiple sclerosis were the most frequently mentioned therapeutic areas (cited in 92, 84 and 80 webpages, respectively), which did not always match those for which there is regulatory approval. Information was also incomplete, with only 22% of the webpages mentioning potential side effects. Health portal websites provided the most complete information, with all of them (n = 7) reporting side effects. On average, 80% of webpages had a neutral stance on the potential benefits of medical cannabis, with commercial websites having more frequently a positive stance (67%).
    CONCLUSIONS: We conclude that the information that can be found online is not always aligned in terms of the therapeutic areas for which science-based evidence is often still weak.

      OBJECTIVE: To describe and assess the quality and accuracy of the most highly viewed YouTube and TikTok posts related to urinary tract infections (UTIs). Social media is increasingly a resource for health information. YouTube and TikTok videos are highly utilized and are potentially a source of helpful information or misinformation.METHODS: During January 2021, "UTI" was searched within YouTube and TikTok and the most relevant videos were identified and analyzed for their content. Accuracy of scientific information, possible misinformation, and credibility of the videos was rated independently by three reviewers. Posts were categorized as educational/informational, shared experience, humor/entertainment, and home remedies/alternative therapies.
    RESULTS AND CONCLUSIONS: In 50 YouTube and 50 TikTok videos respectively, the median number of views was 49K and 1.4M, the median number of likes was 296 and 58K, and the median number of comments was 50 and 616. The proportion of female to male presenters was equal for YouTube videos while 94% of those from TikTok were female. Overall, YouTube videos had higher median scores for scientific information, credibility, and less misinformation compared to TikTok. YouTube videos with more views, likes, and comments tended to have lower scores in all categories and more misinformation. More presenters were medical professionals on YouTube videos than those on TikTok. While videos from both platforms contained misinformation, none promoted misinformation that would cause harm to health. Healthcare providers should be aware of the potential influence of social media as patients are getting health information from many sources.

      INTRODUCTION: Various online platforms, such as YouTube, are used for surgical education. Esophageal surgery is sophisticated and surgical videos may help reduce the time it takes for surgeons to learn these complicated operations. There is no clear consensus regarding the quality and reliability of esophagectomy videos on YouTube. We aimed to evaluate esophageal surgery videos published on YouTube in terms of quality and reliability.METHODS: The keywords "esophagectomy" and "surgery" were both searched on YouTube and the first 150 results were evaluated. Eighty two videos were included in the analysis. The quality and reliability of the videos were determined using the esophagectomy scoring system (ESS) developed by the authors, the Journal of the American Medical Association benchmark criteria, and the video power index.
    RESULTS: A total of 82 videos were reviewed. About two-thirds of the videos demonstrated the Ivor Lewis technique and included surgeries performed using the thoracoscopic/laparoscopic method. The videos were analyzed as per the source of the upload: academic (25.7%), industry-sponsored (9.7%), or individual (64.6%). When the scores were compared by the origin of the videos, industry-sponsored videos scored significantly higher than the videos produced by individuals and academic centers (P = 0.01). While the ESS and Journal of the American Medical Association benchmark criteria scores were significantly correlated (P = 0.00), no correlation was found between video length, video power index score, and ESS score.
    CONCLUSIONS: Conducting a professional evaluation of videos before they are published on YouTube may enhance video quality. Moreover, valuable videos of better quality can be produced by improving the ESS and by assessing more videos.

      BACKGROUND: Patient education is a key element in the management of asthma.AIMS: This study aimed to evaluate the popularity and usefulness of YouTube videos on asthma.
    METHODS: Two authors screened and evaluated the 200 most popular videos. Data on likes, dislikes, views, comment, source of uploader, days since upload, and usefulness were recorded and included for analyses. The usefulness of the videos was categorized as follows: useful, misleading, or neutral. Misleading videos provided at least one scientifically incorrect detail, whereas useful videos contained scientifically correct information.
    RESULTS: A total of 130 videos were included, and the total number of views was 100,290,242 with a total duration of 29 h and 8 min. While 26.6% of videos were uploaded by TV shows and YouTube channels, only 7.7% were uploaded by lung specialists. 65.4% of the videos contained scientifically correct information, whereas 18.5% contained misleading information. Although videos from medical professionals had a higher quality than videos from YouTube channels and TV shows, the latter were more popular. Misleading videos had numerically, but not statistically significant higher views compared with useful videos.
    CONCLUSIONS: YouTube videos on asthma are popular in terms of viewer interaction, and the popularity is not restricted to videos uploaded by professional sources. Although more than half of the videos were found to be useful, a non-negligible proportion of videos were assessed as misleading. The usefulness of YouTube videos on asthma is variable and initiatives should be taken to increase the potential of YouTube as an useful source in patient education.

      Objectives  This article evaluates the completeness and accuracy of YouTube videos related to endoscopic transsphenoidal surgery (ETS) as a source for patient information. Design  YouTube was searched using relevant terms pertaining to ETS. Videos were evaluated independently by two physician reviewers experienced in ETS. Video demographics including uploader source along with validity scores based on predetermined checklists were captured. Setting  Internet. Participants  Not applicable. Main Outcome Measures  A novel ETS scoring checklist, the modified DISCERN criteria, and Journal of the American Medical Association (JAMA) benchmark score were used to measure completeness and accuracy of videos. video power index (VPI) was calculated to reflect popularity. Intraclass correlation coefficient was calculated for rater agreement. Results  Seventy-nine videos were included in final scoring and analysis. The ETS score, DISCERN, JAMA, and mean VPI across all included videos were 5.0 ± 2.7, 2.4 ± 0.83, 2.19 ± 0.62, and 8.92 ± 18.1, respectively. Based on the ETS score checklist, 31 (39%) of the videos were rated as poor, 30 (38%) were moderately useful, 17 (22%) were useful, and 1 (1%) was exceptional. There was a significant positive correlation between the ETS, DISCERN, and JAMA scores ( p  < 0.001), but no correlation with VPI and the validity scores. There were no significant differences comparing validity scores based on the uploader source. Conclusion  YouTube videos related to ETS have limited usefulness and poor overall validity for patient information. Clinicians should direct patients to other validated sources of information and aim to improve the comprehensiveness of ETS-related videos.

      INTRODUCTION: Patients in search of answers to health-related questions often seek out information on the internet. The current study aimed to evaluate the quality of videos on the topic of mesh pertaining to its use in the treatment of stress urinary incontinence or pelvic organ prolapse.METHODS: A total of 100 videos on the topic of mesh on YouTubeTM were screened in this study. From that, a further 30 were selected for review. Five experts in the medical field reviewed each video anonymously, using two video assessment tools. Video characteristics were collected and evaluated. Videos were assessed based on a Global Assessment Score (GAS) and Patient Education Tool for Audiovisual Materials (PEMAT-A/V) scale for ease of patient access and comprehension. The overall correlation between raters and videos was also compared.
    RESULTS: The GAS and PEMAT-A/V ratings correlation across multiple raters demonstrated excellent inter-rater reliability. We found that the overall GAS score and recommendation was substandard, and the median PEMAT-A/V understandability score was 70% (poorly understandable). Most videos contained some form of marketing, and a scarce number had reliable sources of information. Evidence of neutrality was low.
    CONCLUSIONS: Through the expert assessment of videos using quality assessment tools, this study demonstrated the overall variable quality of mesh videos on YouTubeTM and the need for further education regarding patient resources.

      INTRODUCTION: This study aimed to evaluate the content, reliability, and quality of YouTube videos for early orthodontic treatment.METHODS: YouTube video searches were carried out using the keyword "early orthodontic treatment," which was determined using Google Trends. After sorting according to relevance, the first 120 videos were observed, and 61 videos were analyzed accordingly. Further, the general characteristics, uploader source, reliability score (RS), global quality scale (GQS), video information quality index, audiovisual quality, viewers' interaction index, viewing rate, and total information content score (TCS) data belonging to these videos were analyzed. Based on their reliability scores, videos were divided into 2 main groups (low and medium/high information content) accordingly.
    RESULTS: It was found that 25 (41%) of the videos had medium/high information content, and 36 (59%) had low information content, respectively. Videos with medium/high information content were found to have long video durations, increased comments, and high TCS, GQS, RS, and video information quality index scores (P <0.05). The videos uploaded by doctors had increased comments, long duration, and high TCS, GQS, and RS scores (P <0.05).
    CONCLUSIONS: The quality of the information provided by YouTube videos on early orthodontic treatment was generally insufficient. In addition, the information quality was high for videos uploaded by doctors.

      Hearing aids are effective at improving listening ability and health-related quality of life. Recently, we observed that there are many hearing aids-related videos published on TikTok. However, the quality of the information they offer remains unstudied. This study aimed to evaluate the information quality of hearing aids videos on TikTok. We collected a sample of 155 hearing aids-related videos in Chinese and extracted the basic information. First, we identified the source of each video. Two independent raters assessed the quality of the information in the videos, using the PEMAT-A/V tool and DISCERN instrument. Regarding content, the results showed that the video contents on TikTok mainly about features, functionalities, and suggestions of purchase or fitting of hearing aids, while the information about the disadvantages and complications of hearing aids was limited. The overall quality of the hearing aids-related videos was acceptable on average, although the quality varies greatly depending on the type of source. Patients should be cautious in obtaining information about hearing aids on TikTok.

      Introduction  The internet presents a rich milieu of multimedia options relating to pituitary and endoscopic skull base surgery (ESBS). Misinformation can create discordance between patient and provider expectations. The purpose of this study is to analyze the understandability and actionability of available ESBS and pituitary surgery audiovisual information on YouTube and Google. Methods  The top 50 videos generated by searching "pituitary surgery/transsphenoidal surgery" and "endoscopic skull base surgery" in both YouTube and Google were sorted by relevance. Two independent reviewers evaluated each for understandability and actionability based on the Patient Education Materials Assessment Tool for audiovisual material (PEMAT-A/V). Source, authorship, audience, and education/advertisement variables were collected. Chi-square test followed by univariate and multivariate regression analyses assessed the association between these variables and quality. Results  A total of 85 videos (52 YouTube and 33 Google) met inclusion criteria for analysis. There was no significant difference in the presence of the aforementioned variables between YouTube and Google ( p  < 0.05). Also, 72% of videos targeted patients and 28% targeted surgeons. Academic institutions uploaded 58% of videos. Surgeon-targeted videos were more educational ( p  = 0.01) and patient-targeted videos involved more advertisement ( p  = 0.01). Understandability and actionability scores were below the 70% threshold for both YouTube (65 ± 15, 38 ± 33, p  = 0.65) and Google (66 ± 12, 38 ± 26, p  = 0.94). Patient-targeted videos ( p  = 0.002) were more understandable, while surgeon- ( p  < 0.001) and education-focused videos ( p  < 0.001) were more actionable. Conclusion  Understandability and actionability of YouTube and Google audiovisual patient information on ESBS and pituitary surgery is poor. Consideration should be given to the formation of a standardized patient information resource.
