      BACKGROUND: Decision-makers increasingly request rapid answers to clinical or public health questions. To save time, personnel, and financial resources, rapid reviews streamline the methodological steps of the systematic review process. We aimed to explore the validity of a rapid review approach that combines a substantially abbreviated literature search with a single-reviewer screening of abstracts and full texts using three case studies.METHODS: We used a convenience sample of three ongoing Cochrane reviews as reference standards. Two reviews addressed oncological topics and one addressed a public health topic. For each of the three topics, three reviewers screened the literature independently. Our primary outcome was the change in conclusions between the rapid reviews and the respective Cochrane reviews. In case the rapid approach missed studies, we recalculated the meta-analyses for the main outcomes and asked Cochrane review authors if the new body of evidence would change their original conclusion compared with the reference standards. Additionally, we assessed the sensitivity of the rapid review approach compared with the results of the original Cochrane reviews.
    RESULTS: For the two oncological topics (case studies 1 and 2), the three rapid reviews each yielded the same conclusions as the Cochrane reviews. However, the authors would have had less certainty about their conclusion in case study 2. For case study 3, the public health topic, only one of the three rapid reviews led to the same conclusion as the Cochrane review. The other two rapid reviews provided insufficient information for the authors to draw conclusions. Using the rapid review approach, the sensitivity was 100% (3 of 3) for case study 1. For case study 2, the three rapid reviews identified 40% (4 of 10), 50% (5 of 10), and 60% (6 of 10) of the included studies, respectively; for case study 3, the respective numbers were 38% (8 of 21), 43% (9 of 21), and 48% (10 of 21).
    CONCLUSIONS: Within the limitations of these case studies, a rapid review approach that combines abbreviated literature searches with single-reviewer screening may be feasible for focused clinical questions. For complex public health topics, sensitivity seems to be insufficient.

      BACKGROUND: Keeping up to date with the latest medical information using Web-based resources has been sparsely described, and a comprehensive up-to-date review is needed.OBJECTIVES: To summarise the Web-based 'channels' that may assist the actors of the health care system (clinicians, medical researchers and students) to keep up to date with medical information.
    METHODS: We searched PubMed and Scopus for English language articles published between January 1990 and February 2019 that investigated ways for keeping up with medical information. We used the results from our search and relevant information from other sources to conduct a narrative synthesis.
    RESULTS: We found that resources that push information (e.g. web alerts, medical newsletters, listservs), resources that rely on the active information seeking (e.g. access to health librarians and electronic databases, podcasts, mobile apps), collaborative resources (e.g. web conferences, online journal clubs, web social media) and resources that synthesise information (e.g. bibliometrics, living systematic reviews) can contribute in keeping up with new findings and can enhance evidence-based medicine. Clinicians, medical researchers and students can benefit from the proper use of such Internet-based technological innovations.
    CONCLUSION: Internet provides many resources that can help the actors of the health care system stay up to date with the latest scientific findings.

      BACKGROUND: Numerous questions are generated for physicians during patient care. Facilitators and barriers affect the physicians' clinical information-seeking behaviour. While most health studies have focused on barriers, few have dealt with facilitators.OBJECTIVE: This review aimed to identify facilitators in physicians' information-seeking behaviour to help respond to clinical questions raised during patient care.
    METHODS: A narrative review was conducted, and 9 databases were searched. Selection criteria included original articles in the context of patient care and full-text articles published in the English language from 2002 to 2019. The articles were selected and analysed by group discussions.
    RESULTS: Analysis of studies disclosed personal, technical and organisational facilitators including 26 themes. Internet utilisation and information searching skills, more available time, personal interests and knowing preferred sites or textbooks were among the personal factors. The most common technical factors included providing navigation support, and ease of searching and finding needed information. The most commonly reported factors at the organisational level are closeness to Internet facility and access during the consultation.
    CONCLUSION: Information systems designers, health service managers and librarians may need to work together to provide systems and settings that encourage doctors to seek information to answer their clinical questions during patient care.

      The Internet has the potential to be a valuable resource for the dissemination of health promotion information to the general population, mainly in conditions with well-developed health and digital literacy. Few studies have been undertaken on the adoption of the Internet by the Mexican population and its use to seek health information. The aim of this paper was to identify the factors that determine Internet adoption and its use by the heads of Mexican households for obtaining health information. This study used data taken from a probabilistic and cross-sectional national survey (National Survey on the Availability and Use of Information Technologies in Households, or ENDUTIH), applying an economic approach based on utility maximization theory. We estimated a univariate probit model for Internet adoption and a consecutive bivariate probit model with sample selection for the use of the Internet to seek health information. The software package was used to adjust and estimate the proposed models. The first model (Internet adoption) identified several factors related to digital divides in the country, while the second (Internet use to seek health information) identified various factors influencing online searches for health information, such as the following: being a woman; being an adult; having a higher level of education; having a higher income; having superior digital skills; and, living in an urban area. This study highlights the need to strengthen digital policy in order to improve access to and the adoption and efficient use of the Internet, particularly in terms of improving an individual's engagement with their own health.

      Introduction The current coronavirus disease 19 (COVID-19) outbreak has been declared to be a pandemic by the World Health Organization (WHO). It is evolving daily and has jeopardized life globally across social and economic fronts. One of the six key strategic objectives identified by the WHO to manage COVID-19 is to communicate critical information to all communities and prevent the spread of misinformation. We analyzed content on YouTube.com, a widely used web-based platform for medical and epidemiological information. Methods YouTube search results using two keywords were analyzed each in six languages - English, Arabic, Bengali, Dutch, Hindi, and Nigerian Pidgin on April 8, 2020. Forty videos in each of the six languages (i.e., a total of 240 videos) were included for analysis in the study. Two reviewers conducted independent analyses for each language. The inter-observer agreement was evaluated with the kappa coefficient (κ). Modified DISCERN index and Medical Information and Content Index (MICI) scores were used for the reliability of content presented in the videos and information quality assessment, respectively. Analysis of variance, Kruskal-Wallis, Mann-Whitney test, and chi-square tests were done appropriately for data analysis. A p-value of less than 0.05 was considered statistically significant. All calculations were performed using SPSS Statistics for Windows, Version 21.0 (IBM Corp, Armonk, NY). Results The videos cumulatively attracted 364,080,193 views. Altogether, 52.5% of videos were Informative, 23.75% were News Updates, and 8.33% were Personal Experiences. Ten percent of videos were found to present medically misleading information. Independent Users contributed 75% of the misleading content. The overall Mean DISCERN score, an index of content reliability, was 2.62/5. The overall Mean MICI Score was 5.68/25. Videos had better scores in the Transmission component of the MICI scale and scored low on the Screening/Testing component. Conclusion The reliability and quality of the content of most videos about COVID-19 and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were found to be unsatisfactory. Videos with misleading content were found across all six languages, and sometimes garnered a higher percentage of views than those from credible sources. The share of videos contributed by Government and Health Agencies was low. Medical institutions and health agencies should produce content on widely used platforms like YouTube for quality medical and epidemiological information dissemination.

      Background: Online educational information is highly sought out by patients with infertility. This study aims to assess patient-reported usage and helpfulness of fertility educational material on a clinic website and social media accounts.Methods: Educational material was created on common fertility topics in text and video format and posted on the clinic website and social media accounts. At the first consultation for infertility, patients were provided with a postcard directing them to material online. At the first follow-up appointment, patients were invited to fill out a survey assessing whether patients viewed the online educational material and if they found the information helpful.
    Results: 98.4% (251/255) of patients completed the survey, of which 42.6% (106/249) looked at the online material. Of those who viewed the online information, 99.1% (115/116) found the information helpful or somewhat helpful and 67.6% (73/108) found reading the material online better prepared them for making fertility decisions at their doctor's appointment.
    Conclusion: Patients found online fertility information on the clinic website and social media accounts useful for making fertility treatment decisions. Providing online educational material has the potential to improve patient care by empowering patients with the knowledge to make more informed treatment decisions, and improving the quality of the time spent with the physician.

      INTRODUCTION: Health information is one of the most frequently searched topics on the internet. In this observational cross-sectional study, we evaluated the content of the highest indexed Google search results related to migraine management.METHODS: We identified the five most used search terms related to migraine management via Google Trends in the time period 1 January 2004 to 2 October 2019. We entered each search term into Google's search engine and retrieved the search results from the first three pages from each search query. We stratified the recommended treatment options and evaluated the websites using the DISCERN tool.
    RESULTS: In total, 73 unique websites recommended a total of 77 different migraine treatment options, consisting of 35 (45%) acute and 42 (55%) preventive treatments. For acute treatments, pharmacological options were more frequently recommended (88% of websites), whereas non-pharmacological options were more frequent among preventive treatments (67%). Evaluation of the consumer health information using the DISCERN tool showed that non-governmental organizations had the highest mean total score with 3.8 (±0.19).
    CONCLUSIONS: Googling when looking for migraine treatments reveals a multitude of management proposals of varying quality. Non-governmental organizations provide the overall highest quality of written consumer health information on migraine treatments among search results. We encourage stakeholders to optimize and distribute high-quality and peer-reviewed information on migraine management.

      Accessing and receiving quality healthcare in an unfamiliar health system is a significant challenge for many new immigrants and refugees. This study aims to provide a three-phase model to develop a web-based health information website that helps populations with limited English proficiency (LEP) increase health literacy and improve healthcare service access.METHOD: First, we conducted a needs assessment from community leaders and service providers. Second, we developed contents from credible sources and tested each item using multiple readability tests. Last, we revised each item to lower the readability and retest its readability.
    RESULTS: The average reading level for the original 99 topics was assessed at 10.84 (SD= 3.26). After revisions, we were able to lower the readability to 8.56 (SD= 2.96), which was around two grade levels lower, on average.
    CONCLUSION: the main purpose for building an English based health information website was to assist the population with LEP. By using simple English with lower readability, it will ease the translation process. This study demonstrates a process to develop suitable contents for populations in need. In the future, incorporating visual aid and other multimedia will be beneficial in user engagement and knowledge retention.

      BACKGROUND: Nutrition science is currently facing issues regarding the public's perception of its credibility, with social media (SM) influencers increasingly becoming a key source for nutrition-related information with high engagement rates. Source credibility and, to an extent, authenticity have been widely studied in marketing and communications but have not yet been considered in the context of nutrition or health communication. Thus, an investigation into the factors that impact perceived source and message credibility and authenticity is of interest to inform health communication on SM.OBJECTIVE: This study aims to explore the factors that impact message and source credibility (which includes trustworthiness and expertise) or authenticity judgments on SM platforms to better inform nutrition science SM communication best practices.
    METHODS: A total of 6 databases across a variety of disciplines were searched in March 2019. The inclusion criteria were experimental studies, studies focusing on microblogs, studies focusing on healthy adult populations, and studies focusing on either source credibility or authenticity. Exclusion criteria were studies involving participants aged under 18 years and clinical populations, gray literature, blogs, WeChat conversations, web-based reviews, non-English papers, and studies not involving participants' perceptions.
    RESULTS: Overall, 22 eligible papers were included, giving a total of 25 research studies. Among these studies, Facebook and Twitter were the most common SM platforms investigated. The most effective communication style differed depending on the SM platform. Factors reported to impact credibility included language used online, expertise heuristics, and bandwagon heuristics. No papers were found that assessed authenticity.
    CONCLUSIONS: Credibility and authenticity are important concepts studied extensively in the marketing and communications disciplines; however, further research is required in a health context. Instagram is a less-researched platform in comparison with Facebook and Twitter.
