      INTRODUCTION: This study aimed to predict health information-seeking behavior (HISB) components based on health anxiety among users of public libraries.MATERIALS AND METHODS: This research was a descriptive-correlational study. The statistical population consisted of users of public libraries. Data collection tools included the HISB questionnaire and the Short Form of Health Anxiety Inventory (SHAI).
    RESULTS: The results indicated that health anxiety was a significant predictor of the components of HISB. The illness likelihood had a direct relationship with the components of the need for health information and the purposefulness of health information seeking, and it was inversely related to barriers to obtaining health information. In addition, the preoccupation with illness was directly related to the components of the need for health information, the diversity of health information sources, the time of referring to health information sources, the purposefulness of health information seeking, and evaluation of reasons for referring to the library.
    CONCLUSION: Among the components of health anxiety, preoccupation to the disease has the highest role in the emergence of users' information-seeking behavior.

      Despite their entertainment oriented purpose, social media changed the way users access information, debate, and form their opinions. Recent studies, indeed, showed that users online tend to promote their favored narratives and thus to form polarized groups around a common system of beliefs. Confirmation bias helps to account for users' decisions about whether to spread content, thus creating informational cascades within identifiable communities. At the same time, aggregation of favored information within those communities reinforces selective exposure and group polarization. Along this path, through a thorough quantitative analysis we approach connectivity patterns of 1.2 M Facebook users engaged with two very conflicting narratives: scientific and conspiracy news. Analyzing such data, we quantitatively investigate the effect of two mechanisms (namely challenge avoidance and reinforcement seeking) behind confirmation bias, one of the major drivers of human behavior in social media. We find that challenge avoidance mechanism triggers the emergence of two distinct and polarized groups of users (i.e., echo chambers) who also tend to be surrounded by friends having similar systems of beliefs. Through a network based approach, we show how the reinforcement seeking mechanism limits the influence of neighbors and primarily drives the selection and diffusion of contents even among like-minded users, thus fostering the formation of highly polarized sub-clusters within the same echo chamber. Finally, we show that polarized users reinforce their preexisting beliefs by leveraging the activity of their like-minded neighbors, and this trend grows with the user engagement suggesting how peer influence acts as a support for reinforcement seeking.

      BACKGROUND: In recent years, China has witnessed a surge in medical disputes, including many widely reported violent riots, attacks, and protests in hospitals. Asymmetric information between patient and physicians is one of the most critical enablers in this phenomenon, but the Web has become the primary resource for Chinese Internet applications to learn about health information and could potentially play a role in this pathway to patient-physician interaction and patient-physician trust. While considerable attention has been paid in some countries, there are few researches about China's situation for this issue. The purpose of this quantitative study was to examine the influence of online health information and the online guidance of doctors in patient health information literacy on patient-physician interaction and patient-physician trust in China.METHODS: A web-based survey was conducted to collect data from online applications with health problems. A structural equation modeling was used to analyze the data to test the hypotheses. A total of 446 participants from the Tongji Hospital in Wuhan and Huazhong University of Science and Technology hospital participated in the study.
    RESULTS: Our analysis shows that the usefulness of online health information and the online guidance of doctors both significantly influence the trust of the patient toward physicians and interaction with physicians. Furthermore, the patient-physician interaction also has a significant impact on the patient-physician trust.
    CONCLUSIONS: There are many studies on the influence of online health information on the doctor-patient relationship, whereas a little research has examined this relationship between health information online support from doctors and patient-physician interaction by quantitative empirical analysis. This study also explores the online guidance role of doctors and whether doctor-patient communication will affect the trust of doctors and patients. The practical implications of this study include an improved understanding of the function of online health information and potential impacts regarding the interaction with physicians and trust toward physicians that can be used to resolve conflicts between doctors and patients.

      The internet has become a popular resource to learn about health and to investigate one's own health condition. However, given the large amount of inaccurate information online, people can easily become misinformed. Individuals have always obtained information from outside the formal health care system, so how has the internet changed people's engagement with health information? This review explores how individuals interact with health misinformation online, whether it be through search, user-generated content, or mobile apps. We discuss whether personal access to information is helping or hindering health outcomes and how the perceived trustworthiness of the institutions communicating health has changed over time. To conclude, we propose several constructive strategies for improving the online information ecosystem. Misinformation concerning health has particularly severe consequences with regard to people's quality of life and even their risk of mortality; therefore, understanding it within today's modern context is an extremely important task. Expected final online publication date for the Annual Review of Public Health, Volume 41 is April 1, 2020. Please see for revised estimates.

      INTRODUCTION: Knowledge is a strategic resource in health care organisations and knowledge management (KM) is applied as an effective solution to overcome challenges, such as rising health care cost and increasing demands for improving quality of care. The aim of this review was to identify factors influencing the success of KM process in health care organisations of developed and developing countries.METHODS: This review was conducted in 2018. The sources used for searching relevant papers were PubMed, Scopus, Science Direct, Web of Knowledge, EMBASE and Google Scholar, and the time frame was between 1980 and 2017. The search terms were KM, health care services administration, health care organisation, hospital and clinic which were combined by using AND/OR Boolean operators.
    RESULTS: In this review, 13 papers were included. The main success factors influencing KM implementation in health care organisations were organisational culture, information technology, organisational structure, and performance evaluation and measurement. In developed countries, organisational culture was the most frequent factor, while in developing countries, organisational culture and information technology were the most frequent ones.
    CONCLUSION: It seems that in developed and developing countries, organisational factors are the most frequent factors influencing successful KM in health care organisations.

      Background: The aim of the current study is to determine the Comparison of intellectual structure of International Journal of Preventive Medicine (IJPM) with Medical Subject Headings (MeSH) based on author keywords and index terms of Scopus database and the degree of compatibility among these two groups of keywords.Methods: This study was carried out using a co-word technique, which is one of the bibliometric methods. The study population consisted of 1104 articles published in IJPM and indexed in Scopus database. After retrieval the articles, data for co-word analyses was extracted using UCINET and VOSviewer software applications and centrality criteria. Then, the compatibility of author keywords and MeSH terms was examined by Jaccard's similarity index.
    Results: During the investigated years and among 2402 author keywords, on average, 561 author keywords (23.36%) were exact matches, 417 author keywords (17.36%) were partial matches, and 1424 author keywords (59.28%) were not matched with the terms contained in the index. Author keywords matching or not matching with index-term categories formed the largest portion of partial match keywords.
    Conclusions: The use of MeSH as a standard tool by medical journals for the selection of keywords in scientific publications could improve the visibility and retrieval of articles, and increase the number of citations and journals' impact factor.

      Although there is a large amount of user-generated content about urological health issues on social media, much of this content has not been vetted for information accuracy. In this article, we review the literature on the quality and balance of information on urological health conditions on social networks. Across a wide range of benign and malignant urological conditions, studies show a substantial amount of commercial, biased and/or inaccurate information present on popular social networking sites. The healthcare community should take proactive steps to improve the quality of medical information on social networks. PATIENT SUMMARY: In this review, we examined the spread of misinformation about urological health conditions on social media. We found that a significant amount of the circulating information is commercial, biased or misinformative.

      Purpose: Nutrition care guidelines for the transgender population do not exist, despite significant nutrition-related clinical and psychosocial considerations. Social networking sites (SNSs) provide multidirectional communication and have expanded in popularity among transgender users as a resource for health information and support. The nature of the content shared among the online transgender community is unknown, but may suggest the nutrition-related areas that are of most importance to the transgender population. The objective of this qualitative netnography was to describe the food and nutrition messages shared among the transgender community using video blogs (vlogs) on the SNS, YouTube. Methods: Public vlogs were assessed using the constant comparative method. Pseudoquantitative methods were used to capture the prevalence of each subtheme; quotes were documented verbatim. Data were collected from transgender users' public vlogs (n=30) self-published on YouTube from 2013 to 2018. Results: Six major themes were generated from the data analysis. These included the following: functions of diet and exercise; diet and exercise philosophies; "how to" vlogs; advice for success; using dietary supplements; and effects of hormone therapy. Conclusions: Nutrition-related messages are widely shared among the online transgender community through YouTube. The identified themes reflect topics of interest and expressed needs of transgender individuals. SNSs provide health care providers with a platform to improve patient education and health literacy. Health care providers may actively engage in online discussions to build trust, answer questions, and provide a source of accurate and evidence-based information.

      OBJECTIVE: Murmurs are abnormal audible heart sounds produced by turbulent blood flow. Therefore, murmurs in a child may be a source of anxiety for family members. Families often use online materials to explore possible reasons for these murmurs, given the accessibility of information on the Internet. In this study, we evaluated the quality, understandability, readability, and popularity of online materials about heart murmur.METHODS: An Internet search was performed for "heart murmur" using the Google search engine. The global quality score (on a scale of 1 to 5, corresponding to poor to excellent quality) and Health on the Net code were used to measure the quality of information presented. The understandability of the web pages identified was measured using the Patient Education Materials Assessment Tool (score range from 0 to 100%, scores below 70% reflect poor performance). The readability of each web pages was assessed using four validated indices: the Flesch Reading Ease Score, the Flesch-Kincaid Grade Level, the Gunning Frequency of Gobbledygook, and the Simple Measure of Gobbledygook. The ALEXA traffic tool was used to reference domains' popularity and visibility.
    RESULTS: We identified 230 English-language patient educational materials that discussed heart murmur. After exclusion, a total of 86 web pages were evaluated for this study. The average global quality score was 4.34 (SD = 0.71; range from 3 to 5) indicating that the quality of information of most websites was good. Only 14 (16.3%) websites had Health on the Net certification. The mean understandability score for all Internet-based patient educational materials was 74.6% (SD = 12.8%; range from 31.2 to 93.7%). A score suggesting these Internet-based patient educational materials were "easy to understand". The mean readability levels of all patient educational materials were higher than the recommended sixth-grade reading level, according to all indices applied. This means that the level of readability is difficult. The average grade level for all web pages was 10.4 ± 1.65 (range from 7.53 to 14.13). The Flesch-Kincaid Grade level was 10 ± 1.81, the Gunning Frequency of Gobbledygook level was 12.1 ± 1.85, and the Simple Measure of Gobbledygook level was 9.1 ± 1.38. The average Flesch Reading Ease Score was 55 ± 9.1 (range from 32.4 to 72.9).
    CONCLUSION: We demonstrated that web pages describing heart murmurs were understandable and high quality. However, the readability level of the websites was above the recommended sixth-grade reading level. Readability of written materials from online sources need to be improved. However, care must be taken to ensure that the information of web pages is of a high quality and understandable.

      Data is foundational to high-quality artificial intelligence (AI). Given that a substantial amount of clinically relevant information is embedded in unstructured data, natural language processing (NLP) plays an essential role in extracting valuable information that can benefit decision making, administration reporting, and research. Here, we share several desiderata pertaining to development and usage of NLP systems, derived from two decades of experience implementing clinical NLP at the Mayo Clinic, to inform the healthcare AI community. Using a framework, we developed as an example implementation, the desiderata emphasize the importance of a user-friendly platform, efficient collection of domain expert inputs, seamless integration with clinical data, and a highly scalable computing infrastructure.

      INTRODUCTION: YouTube® has become a common health information source for patients. Recent studies have determined that videos on YouTube® contain misleading and inappropriate information for different medical conditions. The aim of the present study was to assess the quality and reliability of videos pertaining to rotator cuff (RC) repair surgery.HYPOTHESIS: YouTube® users prefer watching videos with high educational quality which are provided by physicians.
    MATERIAL AND METHODS: A search was performed using keywords "rotator cuff surgery" and "rotator cuff repair" on YouTube® and the first 100 videos for each keyword were analyzed. Video source, time since upload, duration, and number of views, likes, and dislikes were recorded. Video popularity was reported using the video power index (VPI) and view ratio. Video educational quality was measured using the recognized DISCERN, the Journal of the American Medical Association (JAMA) score and a novel RC-specific score (RCSS).
    RESULTS: Among the 200 videos identified, 67 were included. The mean duration was 7.7minutes and the mean number of the views was 147,430. Videos uploaded by a physician had significantly higher DISCERN, JAMA, and RCSS (p<0.001). While the main video source was physicians (48%), the most popular videos were uploaded by patients and commercial websites, according to the VPI and view ratios. The number of likes, view ratios, and VPI were negatively correlated with each score. There were negative correlations between duration and VPI scores, and positive correlations with DISCERN, JAMA score, and RCSS. Animated videos showed significantly lower results for all quality scores (p<0.05), while their VPI was significantly higher (p<0.01).
    DISCUSSION: Online information on RC repair surgery provided by YouTube® was low quality, despite being mostly uploaded by physicians and having relatively higher quality scores. YouTube® users prefer watching low quality videos which were provided by patients and commercial websites.
