Health information quality on the internet in urological oncology: a multilingual longitudinal evaluation

Assessment of the Readability and Quality of Online Information for Patients and Their Families Regarding Schizophrenia

ABSTRACT

To our knowledge, this is the first study that specifically aims to assess the readability and quality of online information about schizophrenia. The analysis is performed on 93 of 195 websites that appeared in an advanced Google search of the term "schizophrenia" performed on a single day. The websites were categorized as commercial, nonprofit, professional, and government. The websites were evaluated using the Health on the Net Foundation (HON) code certificate, DISCERN tool, and Journal of the American Medical Association ( JAMA ) benchmark criteria for quality and the Flesch Reading Ease Formula, Flesch-Kincaid Grade Level (FKGL) Formula, Simple Measure of Gobbledygook, and Gunning Fog indices for readability. A total of 21.5% of all websites had a HON code certificate, 50.5% were accepted as high quality ( JAMA score ≥3), and 25.8% reached the recommended readability level (FKGL ≤8). Only three websites scored at a fifth- to sixth-grade reading level. Commercial and government websites had significantly lower DISCERN scores. Commercial websites had significantly lower Flesch Reading Ease Score and FKGL score than nonprofit websites. In conclusion, the current findings indicate that the quality of online information on schizophrenia is generally acceptable, but the readability is insufficient. Website creators, physicians, and health authorities should be more sensitive to the readability of online information about schizophrenia, considering the poor cognitive capacity of the patients and the unique nature of the disease.

What Our Patients and Their Families Are Reading: Quality and Readability of Internet Information About Electroconvulsive Therapy

OBJECTIVES

The Internet is now more widely used than before by psychiatric patients and their families to search for medical conditions and treatments. To our knowledge, no study has addressed the quality and readability of online information about electroconvulsive therapy (ECT). We aimed to examine the quality and readability of English-language Internet information related to ECT.

METHODS

An advanced search of Internet Web sites containing information about ECT was conducted by using the search term "ECT or electroconvulsive therapy." The resulting Web sites were categorized into 1 of 3 categories (commercial, nonprofit, or professional organizations). Their quality was evaluated using Health on the Net code certification, the Journal of the American Medical Association (JAMA) benchmark criteria, and the DISCERN tool. The readability of the Web sites was assessed using the Flesch Reading Ease, Flesch-Kincaid Grade Level Formula, Simple Measure of Gobbledygook, and Gunning Fog indexes.

RESULTS

A total of 86 Web sites were included in the analysis. Of all these Web sites, 18 (20.9%) had a Health on the Net code certificate, and 16 (18.6%) were accepted as high quality (JAMA total score ≥3). The commercial Web sites had significantly lower DISCERN and JAMA benchmark scores compared with the other Web sites. A total of 30.23% of all the Web sites reached the recommended readability level (Flesch-Kincaid Grade Level Formula ≤ 8). Moreover, only 4 scored at the grade 5 to 6 reading level, which is considered ideal for patient educational materials.

CONCLUSIONS

Our study indicates that both the quality and readability of online information about ECT are not at the desired level. Physicians, patients, and their families should consider this failure in relation to online information about ECT. In addition, Web site creators and health authorities should be aware of their responsibilities for providing quality and readable health information to the public.

A Readability Analysis of Online Spondylolisthesis and Spondylolysis Patient Resources Among Pediatric Hospital Web Pages: A US-Based Study

INTRODUCTION

With the increasing use of the internet for health information, it is essential to prioritize resources that match the reading level of patients and parents. Limited health literacy is a notable issue in the United States, creating a financial burden and negatively affecting patient outcomes. This study aimed to assess the availability and readability of pediatric hospital web pages concerning two prevalent spine conditions in children, spondylolisthesis and spondylolysis, specifically examining whether the available resources meet the recommended sixth grade reading level.

METHODS

A total of 179 pediatric hospital web pages were assessed for their availability and readability of spondylolisthesis and spondylolysis patient information. The web pages' readability was assessed using five readability formulae. Descriptive statistics and Student t-tests were performed on the collected scores with significance set at P < 0.05.

RESULTS

Among the analyzed hospitals, 40.2% had no information on spondylolisthesis or spondylolysis, 20.1% mentioned treating these conditions, 7.8% had < 100 dedicated words, and only 31.8% had dedicated web pages with more than 100 words on these conditions. The average reading grade level for the evaluated web pages was 12.0, indicating a high school education level is required for comprehension. None of the web pages were written below the recommended sixth grade reading level.

DISCUSSION

The readability of the limited resources was markedly higher than the recommended reading level. In addition, this study emphasizes the need for enhanced accessibility and readability of online patient information from pediatric hospitals to improve parental comprehension and informed decision-making. Physicians should consider identifying online resources that they consider of high quality and acceptable readability to support better patient understanding and outcomes.

Prostate cancer, online health information and communication technology - Bibliometric analysis of field with research frontiers

OBJECTIVES

The purpose of this study is to conduct the first bibliometric analysis which examines eHealth communication technologies in prostate cancer care, and the utilization of internet-based health information and communication technology by men with prostate cancer.

METHODS

Original articles were extracted from the Science Citation Index Expanded (SCI-E) on Web of Science (WOS) and analyzed concerning their distributions. Quantitative guidance directed investigation of findings from previous studies and trending issues within the field. The WOS, VOSViewer and CiteSpace IV were used for information analysis.

RESULTS

302 articles were included in the final analysis. There has been a 165 % increase in productivity over the past decade. The leading country by publication was the USA (145 articles = 48.02 %). Journals which published the highest number of original articles were the Journal of Medical Internet Research (6.95 %), and Patient Education and Counseling (4.64 %).

DISCUSSION AND PRACTICE IMPLICATIONS

The field of research which examines utilization and impacts of internet-based health information on men with prostate cancer is growing and diverse. Research frontiers are 'Information quality and diversity', 'eHealth literacy', 'decision making', and 'survivorship and advanced disease'. Clinicians should be aware of several significant limitations which exist within the current field of research.

Quality of information regarding abnormal uterine bleeding available online

INTRODUCTION

The Internet and electronic devices with Internet access allow for a greater fluidity of information and speed of communication, especially in the field of health. Abnormal uterine bleeding (AUB) affects approximately 3-30% of women and can negatively impact their health and quality of life. Information regarding AUB that is available on the Internet may not be clear or accurate, rendering it difficult to understand and likely to result in delayed medical evaluation, which subsequently leads to worsening of the AUB.

OBJECTIVE

To evaluate the quality of the information regarding AUB currently available on the Internet, including information regarding treatments.

METHODS

The Google Trends website was searched for the most widely used English terms related to AUB. The identified descriptors were searched individually on the Google, Yahoo!, and Bing search engines. The first 10 results of each search were pre-selected and evaluated for inclusion in this study. Selected websites were categorically divided into two groups (news/magazine and academic) and individually analyzed by three experts using the DISCERN quality criteria (reliability, general quality, and quality of information) and the presence or absence of the Health on the Net Foundation Code of Conduct (HONcode®) seal.

RESULTS

Of the 168 websites included in this study, 60.1% were allocated to the news/magazine group and 39.9% were allocated to the academic group. Over half of the websites (54.2%) did not have the HONcode® quality seal. Websites in the academic group were more likely to include accurate information regarding AUB with greater reliability than websites in the news/magazine group. There were no statistical differences regarding the general quality of the websites. Most websites were rated as either moderate quality (70.8%) or low quality (28.6%). The HONcode® criterion was found to be a confounding factor of the analyses, as the grouping and quality results of websites without this seal were significantly associated. In addition, websites in the news/magazines group were 6.7 times more likely to provide low quality information than websites in the academic group (odds ratio: 6.7; 95% confidence interval: 2.1-21.4).

CONCLUSION

The information regarding AUB that is available on the Internet is of low to moderate quality. Academic websites present more reliable information of greater quality. The presence of the HONcode® seal is considered important to determine the quality of the content of a website, especially for news/magazine websites, and may help Internet users identify websites that contain more reliable information. Algorithms and applications that categorize the quality of information and the reliability of health content may be useful tools that can help patients clarify their symptoms for several conditions including AUB.

Online information analysis on pancreatic cancer in Korea using structural topic model

Inappropriate information on a deadly and rare disease can make people vulnerable to problematic decisions, leading to irreversible bad outcomes. This study explored online information exchanges on pancreatic cancer. We collected 35,596 questions and 83,888 answers related to pancreatic cancer from January 1, 2003 to May 31, 2020, from Naver, the most popular Korean web portal. We also collected 8495 news articles related to pancreatic cancer during the same period. The study methods employed were structural topic modeling, keyword frequency analysis, and qualitative coding of medical professionals. The number of questions and news articles increased over time. In Naver's questions, topics on symptoms and diagnostic tests regarding pancreatic cancer increased in proportion. The news topics on new technologies related to pancreatic cancer from various companies increased as well. The use of words related to back pain-which is not an important early symptom in pancreatic cancer-and biomarker tests using blood increased over time in Naver's questions. Based on 100 question samples related to symptoms and diagnostic tests and an analysis of the threaded answers' appropriateness, there was considerable misinformation and commercialized information in both categories.

Online urological educational material for medical students: can search engines be trusted?

OBJECTIVES

To determine the credibility of online urological information that medical students are likely to encounter, determine possible discrepancies between the credibility of information pertaining to different areas within urology (especially those less relevant to patients), and assess trends in the sponsorship of online urological educational material.

MATERIALS AND METHODS

Health on the Net (HON) principles were used as a validated benchmark to assess the reliability of websites that appeared in the first 150 results of a search using the Google search engine. A variety of urological search terms were used, grouped into three broad categories with varying relevance to patients and medical students. Further analysis focussed on the sponsorship of assessed websites.

RESULTS

A total of 5400 websites were assessed for validation over a set of 36 search terms. Only 843/5400 (15.6%) of these were HONcode accredited, indicating a large proportion of unverified and potentially unreliable information. Search engine rankings usually favoured accredited websites (P = 0.009), and accreditation peaked at 51.1% (184/360) in the first page of results, but sorting became weaker outside the highest search results. The percentage of accredited websites varied significantly between different subcategories of search terms such as conditions (18.3% [329/1800], P = 0.003) and procedures (13.5% [243/1800], P = 0.043). Governmental/educational and commercial sources supported the majority of websites assessed for sponsorship (21% [31/150] and 33% [49/150], respectively), and the former were more likely to rank highly in search results.

CONCLUSION

Online urological information frequently lacks validation and is often of indeterminate credibility. There is a marked decrease in the proportion of accredited websites beyond the highest-ranked results and when considering search categories more relevant to students and less relevant to patients. Students cannot necessarily rely on free online sources for accurate information and could benefit from the development of more rigorous novel tools and platforms.

Platelet-Rich Plasma for Knee Osteoarthritis: Internet Marketing and Patient Education-An Appraisal of Content for Websites with the Greatest Search Engine Visibility

OBJECTIVE

The internet is increasingly being used as a resource for health-related information by the general public. We sought to establish the authorship, content, and accuracy of the information available online regarding platelet-rich plasma (PRP) therapy for knee osteoarthritis.

DESIGN

Top 200 search results from each of the 3 leading search engines available online (Google, Yahoo!, Bing) were screened, and 181 websites were finally reviewed for content with emphasis on specific claims, comparing between websites authored by private physicians/groups and other authorship types.

RESULTS

Nearly 80% of the websites claimed that PRP injections for osteoarthritis of the knee improve patients' pain. A total of 42.8% of the private websites and 27.6% of nonprivate websites have stated that the procedure can delay or eliminate the need for future surgery. Costs were only mentioned by few (11.6%), and mainly by the nonprivate websites. Both website groups were unlikely to mention that PRP therapy is not the treatment of choice for end-stage knee osteoarthritis (7.9% of private and 17.2% of the nonprivate sites), or to state that patients with less advanced disease may benefit more from the treatment (11.8% and 20.6%, respectively). Private websites were less likely to refer to peer-reviewed literature (18.4% vs. 41.4%) and were more than 3 times less likely to mention lack of adequate evidence (13.2% vs. 48.2%).

CONCLUSIONS

Patients seeking online information regarding PRP therapy are vulnerable to websites presenting a narrow viewpoint of this treatment modality, putting emphasis on unsubstantiated benefits while disregarding potential drawbacks and concerns.

Bladder Cancer and Google Trends: Associations Between US Search Patterns and Disease Outcomes May Show Need for Improved Awareness Strategies

Interest in and awareness of bladder cancer may translate to better health-seeking behaviors and earlier detection, given modifiable risk factors such as smoking. We assessed bladder cancer interest in the USA over the past 15 years as reflected by Internet search trends, and correlated these trends with epidemiologic patterns in bladder cancer. Google Trends was used to estimate US bladder cancer interest in the unit search volume index (SVI), which estimates the volume of online search activity for a specified period relative to the highest volume of searches within a specified location. Between January 2004 and June 2019, SVIs were collected for the search term "bladder cancer" and other related search terms. To evaluate the effect of public awareness campaigns, the SVIs for the month of May (US bladder cancer awareness month) were compared with the SVIs of all other months. Correlations between "bladder cancer" SVI and incidence, mortality, and mortality-to-incidence ratio (proxy for survival) by state were evaluated. There was no increase in the relative search volumes for "bladder cancer" during the national bladder cancer awareness month compared with all other months (p = 0.27). By state, there were positive correlations between SVIs of "bladder cancer" and incidence (R = 0.72, p < 0.001) and mortality (R = 0.47, p < 0.001). However, there was no correlation between SVIs and mortality-to-incidence ratio (R = - 0.24, p = 0.08). Interest in bladder cancer is positively associated with disease incidence and mortality but not survival, suggesting interest is driven by new diagnoses or deaths, and not early detection that can improve survival. Our findings may show the need for better public education endeavors.

Evaluating Local Multilingual Health Care Information Environments on the Internet: A Pilot Study

For foreign-born populations, difficulty in finding health care information in their primary language is a structural barrier to accessing timely health care. While such information may be available at a national level, it may not always be relevant or appropriate to the living situations of these people. Our objective was to explore the quality of online multilingual health information environments by pilot-testing a framework for assessing such information at the prefectural level in Japan. The framework consisted of five health care domains (health system, hospitals, emergency services, medical interpreters, and health insurance). Framework scores varied considerably among prefectures; many resources were machine-translated. These scores were significantly associated with foreign population proportion and the number of hospitals in each prefecture. Our multilingual health care information environment (MHCIE) framework provides a measure of health access inclusivity, which has not been quantified before. It is adaptable to other international contexts, but further validation is required.

Readability, understandability, and quality of retinopathy of prematurity information on the web

BACKGROUND

The purpose of this study is to assess the readability, understandability, and quality of information on retinopathy of prematurity presented at websites frequently visited by parents.

METHODS

A total of 220 websites were assessed, which were recruited by searching for "retinopathy of prematurity" at the Google search engine. The readability of each web page was assessed by Flesch Reading Ease Score, Gobbledygook's Gunning Frequency, Flesch Kincaid Grade Level, Coleman Liau score, The Simple Measure of Gobbledygook, Fry Graph Readability Formula, and Automated readability score. The understandability of the web pages included in the study was measured by using the Patient Education Materials Assessment Tool. Quality was evaluated using Health in Net code and JAMA. The ALEXA traffic tool was used to reference the domains' popularity and visibility.

RESULTS

Sixty-four websites were included to the study. The average Flesch Reading Ease Score was 50.1 ± 11.4, Gunning Frequency of Gobbledygook level was 13.4 ± 2.5, The Flesch-Kincaid Grade level was 10.7 ± 2.2, Coleman Liau level was 10.8 ± 1.7, Simple Measure of Gobbledygook level was 10.0 ± 1.9, and Fry Graph Readability Formula 11.9 ± 2.7, Automated readability score 10.4 ± 2.5. The average understandability score for all website-based patient education materials was 76.9 ± 15.2. Total JAMA Benchmark score is 2.27 ± 1.14 (range from 1 to 4). The quality of information at most websites were determined by our chosen assessments to not to be good.

CONCLUSION

Websites addressed to parents for retinopathy of prematurity had found to have high understandability. It was concluded based on this study that readability and quality of presented written materials at online sources need to be improved.

Adverse Effects of Radiotherapy and Chemotherapy for Common Malignancies: What Is the Quality of Information Patients Are Finding Online?

Little is known about the availability of high-quality online health information (OHI) for adverse effects (AEs) of radiotherapy (RT) and chemotherapy (CHT). Optimal search strategies for gaining access to high-quality OHI for these topics are not well-established. This study explores the quality of, potential disparities in, and possible search strategies for OHI pertaining to AEs of RT and CHT. One hundred twenty phrases on generalized and malignancy site-specific AEs of RT and CHT were searched on Google. The Health on the Net Foundation (HONcode) framework was applied to assess the quality of the first 100 websites for each search phrase. Comparisons of the availability of high-quality OHI were made between different languages, malignancy sites, and treatment modalities (RT vs CHT). Of the 12,000 RT and CHT AE websites analyzed, approximately half of the first 10 websites returned for each search were HONcode-accredited; approximately a fifth of the first 100 websites returned were HONcode-accredited. Such low availability of high-quality OHI persisted throughout different languages (English, French, Spanish) and common malignancy sites (breast, prostate, lung), with some variations between languages, malignancy sites, and RT vs CHT. Despite the important role of OHI in cancer patients' approach to health information gathering and decision-making, the availability of high-quality OHI for the AEs of common oncologic treatments, RT and CHT, is low across different languages and common malignancy sites. Our findings demonstrate the need for improvement in the availability of high-quality OHI. Therefore, providers should take an active stance in directing patients to high-quality OHI.

Radiation Oncology Online: Quality, Strategies, and Disparities

Although much is known about the quality of online health information (OHI) for many malignancies, the availability of high-quality OHI for oncologic treatments remains undefined. Furthermore, search strategies that improve quality of radiation oncology OHI, and disparities in availability of high-quality OHI, are not well-described. Forty phrases describing malignancies and their treatment modalities (radiation, chemotherapy, and surgery), and 57 phrases describing radiation oncology treatments, including abbreviations for some treatments and translations in different languages, were generated. The Health on the Net Foundation framework for assessing OHI quality was applied to the top 100 websites listed for each search phrase. The availability of high-quality OHI between malignancies and treatment modalities, and among treatment modalities, was compared. The roles of radiation oncology term abbreviation, search result order, patient gender, and language, on availability of high-quality OHI, were also assessed. Among the first 10, 20, and 50 websites for each search phrase, there were significantly more high-quality websites for phrases describing malignancies compared with respective treatment modalities (P < 0.02 for all). There were no differences among treatment modalities. Among radiation oncology treatment phrases, there were no significant differences between searches for full-name phrases and their respective abbreviations, though earlier results were more likely to be of high quality. Gender did not affect quality of OHI, though language did. Availability of high-quality OHI for cancer treatments lags behind that of cancer OHI. For radiation oncology treatment OHI, search strategies and patient disparities highlight potential areas for provider intervention and increased quality of OHI.

Availability and Readability of Online Patient Information on Osteosarcoma: Assessment of Pediatric Hospital and National Cancer Institute-Designated Cancer Center (NCIDCC) Osteosarcoma Web Pages

Online patient information (OPI) plays an important role in pediatric orthopaedic patient/caregiver education and decision-making. We assessed the availability and readability of OPI about osteosarcoma found at pediatric hospital and U.S. National Cancer Institute-designated cancer center (NCIDCC) websites.

Silver lining of COVID-19: Heightened global interest in pneumococcal and influenza vaccines, an infodemiology study

BACKGROUND

Health-seeking behaviors change during pandemics and may increase with regard to illnesses with symptoms similar to the pandemic. The global reaction to COVID-19 may drive interest in vaccines for other diseases.

OBJECTIVES

Our study investigated the correlation between global online interest in COVID-19 and interest in CDC-recommended routine vaccines.

DESIGN, SETTINGS, MEASUREMENTS

This infodemiology study used Google Trends data to quantify worldwide interest in COVID-19 and CDC-recommended vaccines using the unit search volume index (SVI), which estimates volume of online search activity relative to highest volume of searches within a specified period. SVIs from December 30, 2019 to March 30, 2020 were collected for "coronavirus (Virus)" and compared with SVIs of search terms related to CDC-recommended adult vaccines. To account for seasonal variation, we compared SVIs from December 30, 2019 to March 30, 2020 with SVIs from the same months in 2015 to 2019. We performed country-level analyses in ten COVID-19 hotspots and ten countries with low disease burden.

RESULTS

There were significant positive correlations between SVIs for "coronavirus (Virus)" and search terms for pneumococcal (R = 0.89, p < 0.0001) and influenza vaccines (R = 0.93, p < 0.0001) in 2020, which were greater than SVIs for the same terms in 2015-2019 (p = 0.005, p < 0.0001, respectively). Eight in ten COVID-19 hotspots demonstrated significant positive correlations between SVIs for coronavirus and search terms for pneumococcal and influenza vaccines.

LIMITATIONS

SVIs estimate relative changes in online interest and do not represent the interest of people with no Internet access.

CONCLUSION

A peak in worldwide interest in pneumococcal and influenza vaccines coincided with the COVID-19 pandemic in February and March 2020. Trends are likely not seasonal in origin and may be driven by COVID-19 hotspots. Global events may change public perception about the importance of vaccines. Our findings may herald higher demand for pneumonia and influenza vaccines in the upcoming season.

Arthroplasty information on the internet: quality or quantity?

AIMS

Total joint replacement (TJR) is a high-cost, high-volume procedure that impacts patients' quality of life. Informed decisions are important for patients facing TJR. The quality of information provided by websites regarding TJR is highly variable. We aimed to measure the quality of TJR information online.

METHODS

We identified 10,800 websites using 18 TJR-related keywords (conditions and procedures) across the Australian, French, German and Spanish Google search engines. We used the Health on the Net (HON) toolbar to evaluate the first 150 websites downloaded for every keyword in each language. The quality of information on websites was inspected, accounting for differences by language and tertiles. We also undertook an analysis of English websites to explore types of website providers.

RESULTS

'Total joint replacement' had the most results returned (150 million websites), and 9% of websites are HON-accredited. Differences in information quality were seen across search terms (p < 0.001) and tertiles (p < 0.001), but not between languages (p = 0.226). A larger proportion of HON-accredited websites were seen from keywords in the condition and arthroplasty categories. The first tertile contained the highest number of HON-accredited websites for the majority of search terms. Government/educational bodies sponsored the majority of websites.

CONCLUSION

Clinicians must consider the shortage of websites providing validated information, with disparities in both number and quality of websites for TJR conditions and procedures. As such, the challenge for clinicians is to lead the design of reliable, accurate and ethical orthopaedic websites online and direct patients to them. This stands to reward both parties greatly.

Why People Living With and Beyond Cancer Use the Internet

People living with and beyond cancer suffer with a wide range of physical and psychological symptoms. To manage the challenges associated with cancer, patients use a variety of self-management resources, including the Internet. People living with and beyond cancer use the Internet to make decisions regarding their self-care, through information provision, online communities, and support groups. Using the Internet may empower patients, enabling them to feel they have the required knowledge to discuss complementary and alternative treatment options with their health care team. Patients use the Internet because of its practicality; however, there are also several barriers affecting patients with cancer using the Internet, such as lack of information technology skills, lack of computer access, and concerns over the quality of information. Health care professionals need to be aware that the information available on the Internet plays a factor in the decision-making processes regarding using complementary and alternative medicine for self-management. With the use of the Internet as a tool for self-management continuing to grow, it is recommended that more emphasis is placed on health care professionals discussing the role the Internet plays in the decision-making process, to further support their patients regarding self-management for living with and beyond cancer.

'Dr Google': trends in online interest in prostate cancer screening, diagnosis and treatment

OBJECTIVES

To examine trends in online search behaviours related to prostate cancer on a national and regional scale using a dominant major search engine.

MATERIALS AND METHODS

Google Trends was queried using the terms 'prostate cancer', 'prostate-specific antigen' (PSA), and 'prostate biopsy' between January 2004 and January 2019. Search volume index (SVI), a measure of relative search volume on Google, was obtained for all terms and examined by region and time period: pre-US Preventive Services Task Force (USPSTF) Grade D draft recommendation on PSA screening; during the active Grade D recommendation; and after publication of the recent Grade C draft recommendation.

RESULTS

Online interest in PSA screening differed by time period (P < 0.01). The SVI for PSA screening was greater pre-Grade D draft recommendation (82.7) compared to during the recommendation (74.5), while the SVI for PSA screening was higher post-Grade C draft recommendation (90.4) compared to both prior time periods. Similar results were observed for prostate biopsy and prostate cancer searches. At the US state level, online interest in prostate cancer was highest in South Carolina (SVI 100) and lowest in Hawaii (SVI 64). For prostate cancer treatment options, online interest in cryotherapy, prostatectomy and prostate cancer surgery overall increased, while searches for active surveillance, external beam radiation, brachytherapy and high-intensity focused ultrasonography remained stable.

CONCLUSION

Online interest in prostate cancer has changed over time, particularly in accordance with USPSTF screening guidelines. Google Trends may be a useful tool in tracking public interest in prostate cancer screening, diagnosis, and treatment, especially as it relates to major shifts in practice guidelines.

Patient-Focused Online Resources for Melanoma: Highly Variable Content and Quality

When patients are diagnosed or concerned with the diagnosis of melanoma, they commonly use the Internet for information. We assessed the content of patient-focused websites about melanoma. We searched for "melanoma" in four search engines then assessed the first 30 websites in each search. Among included sites, we describe potentially useful content about melanoma: website quality, readability, popularity, and social media sharing. In 31 included websites, > 80% mentioned the definition and risk factors for melanoma, when to seek medical help, how to diagnose, and treatment options, and > 70% described preventive measures. However, website quality was variable: 61% of websites had disclosures, 54% were dated, 41% had a clear author, and 41% had references. Average readability ranged from 8th to 12th grade, which is above recommended reading levels for patient websites. Despite this variation and high reading levels, we identified many high-quality melanoma websites for patients.

Disparity in online health information in pediatric vs. adult surgical conditions

BACKGROUND

Although the quality of online health information (OHI) for adult surgical conditions is well described, the availability of quality OHI for pediatric surgical conditions, and the comparison to that of adult surgical OHI, remains undefined.

METHODS

Medical and lay terms for 15 pediatric and 15 adult surgical conditions were searched using Google in English. The Health on the Net Foundation, a non-governmental OHI accreditation body, designates approval for quality websites. We compared the role of patient population while controlling for disease incidence (pediatric vs. adult), term complexity (medical vs. lay), and order (earlier vs. later listing of websites) on availability of quality OHI among the first 100 websites for each term.

RESULTS

Among the first 100 websites, the adjusted mean number of quality websites was 11.80 for pediatric vs. 17.92 for adult medical search terms, and 13.27 for pediatric vs. 18.20 for adult lay search terms (P < 0.05 for all). Term complexity did not affect quality, and earlier appearing results were more likely to be of high quality.

CONCLUSION

Availability of quality pediatric surgical OHI lags behind that of adult surgical OHI, even when controlling for disease incidence. These findings highlight the potential need for increased quality OHI in pediatric surgery.

Men's health on the web: an analysis of current resources

INTRODUCTION

Men's health research covers a broad range of topics. Men and women face different barriers to health, with men almost universally having a lower life expectancy than women. Access to high-quality information on men's health topics is potentially an important part of engaging men with medical services. We aim to assess the quality of men's health resources available on the internet across 4 developed countries using a tier-based rating system as well as the World Health Organisation Health on the Net (HON) standards.

METHODS

The Google search engine imbedded with the Health on the Net toolbar was used to assess 357 websites across Australia, Canada, America and United Kingdom using the search term 'men's health'. The websites were further subdivided into 3 tiers by 2 independent investigators, with tier 1 websites defined as government or health organisation sponsored, tier 2 websites defined as being sponsored by health services such as private clinics and insurance providers, and tier 3 websites being websites that did not meet criteria for the first 2 tiers.

RESULTS

Overall, 28% of websites were rated as tier 1, 26% as tier 2 and 46% as tier 3. The HONcode accreditation was overall 39% of tier 1 websites. The majority of websites reviewed were in the tier 3 category, and 35% of overall websites being non-health or non-medically related.

DISCUSSION

The lack of 'relevant' and HONcode-accredited websites relating to men's health should be appreciated by health care professionals.

Quality of Health Information on the Internet for Prostate Cancer

Introduction

To compare (1) the quality of prostate cancer health information on the Internet, (2) the difference in quality between websites appearing earlier or later in the search, and (3) the sources of sponsorship for each of these websites.

Materials and methods

The top 150 listed websites on the Google search engine for each of the 11 search terms related to prostate cancer were analysed. Quality was assessed on whether the website conforms to the principles of the Health On the Net Foundation. Each of these websites was then reviewed to determine the main source of sponsorship. Statistical analysis was performed to determine if the proportion of HON accreditation varied among the different cohorts of listed websites and among the 11 search terms used.

Results

In total, 1650 websites were analysed. Among these, 10.5% websites were HON-accredited. The proportion of HON-accredited websites for individual search terms ranged from 3.3% to 19.3%. In comparison with the search term of "Prostate cancer," four search terms had statistically significant odds ratio of the rate of HON accreditation. Websites 51-150 were statistically less likely to have HON accreditation than websites 1-50. The top three website sponsors were journal/universities (28.8%), commercial (28.1%), and physician/surgeon (26.9%).

Conclusions

The lack of validated and unbiased websites for prostate cancer is concerning especially with increasing use of the Internet for health information. Websites sponsored or managed by the government and national departments were most likely to provide impartial health information for prostate cancer. We need to help our patients identify valid and unbiased online health resources.

Testicular Cancer on the Web-an Appropriate Source of Patient Information in Concordance with the European Association of Urology Guidelines?

Despite the continuous growth of the internet, little is known about the quality of online information on testicular cancer, the most common solid malignancy in young men. In our study, we analysed the quality, readability and popularity of the most popular websites on testicular cancer. Therefore, we performed a web search for the term "testicular cancer" using www.google.com . Fifty-one websites were evaluated for HONcode quality certification, Alexa Popularity Rank and readability levels. Furthermore, the websites' content on eight major topics of the current European Association of Urology Guidelines on testicular cancer was assessed. Fourteen (28%) had a HONcode quality certificate and the mean Alexa Popularity Rank of all 51 websites was 54,040 (interquartile range 6648-282,797). Websites were difficult to read requiring 9 years of US school education to properly understand the information. The websites mentioned 80% of the guideline topics on average, revealing "prognosis" (59%) and "follow-up" (57%) as underrepresented subtopics. Furthermore, 12% of all topics were displayed incorrectly, particularly due to wrong information concerning "aetiology" (42%). Sixty percent of the topics were mentioned in an incomplete fashion, with less than half of the websites displaying complete information on "staging" (47%), "diagnostic evaluation" (49%) or "disease management" (45%). In general, online health information concerning testicular cancer is mentioned correctly on most websites. However, improvement regarding readability and completeness of the given information is needed. Nevertheless, highly selected websites on testicular cancer can serve as an appropriate source of patient information.

Online health information and public knowledge, attitudes, and behaviours regarding antibiotics in the UK: Multiple regression analysis of Wellcome Monitor and Eurobarometer Data

Background

Antimicrobial resistance is a global public health problem with some socially patterned drivers. The objective of the study was to investigate associations between use of and trust in the Internet as a source of health-related information and the public’s knowledge, attitudes, and behaviours regarding antibiotics.

Methods

Two representative cross-sectional surveys (the 2015 Wellcome Monitor (n = 1524) and UK segment (n = 1330) of the 2016 Eurobarometer 85.1) covering knowledge about antibiotics and antibiotic consumption were analysed. Knowledge, attitude, and behaviour variables were analysed using regression in relation to demographic characteristics and use and trust in the Internet as a source of information.

Results

The key findings of the analysis are that both use of the Internet as a source of medical research information (variable from the Wellcome Monitor) and trust in the Internet as a source of information about antibiotics (variable from the Eurobarometer) were independently and positively associated with knowledge, attitude, and behaviour regarding antibiotics. Additionally, knowledge about antibiotics was positively associated with behaviour with antibiotics (Wellcome Monitor) and attitude towards finishing antibiotic prescriptions (Eurobarometer). Higher levels of education were associated with better knowledge about antibiotics in both datasets. Older age was positively associated with behaviour and attitude regarding antibiotic consumption.

Conclusions

The Internet is a resource for disseminating quality health information that has the potential to improve stewardship of antibiotics in the community. This study suggests that members of the UK public that use the Internet as a source of health-related information are more likely to be better informed about, and be more responsible with, antibiotics. This mode of information dissemination should be capitalised on to improve antimicrobial stewardship, and further research should examine what the most effective online information sources are in the UK and to what extent their association with behaviour is causal.

General Characteristics and Quality of Stroke-Related Online Information – A Cross-Sectional Assessment of the Romanian and Hungarian Websites

Background: The quality of online health-related information may affect users’ understanding and medical decision-making with dramatic impact, particularly in case of stroke. Objective: The objective of this study was to assess the quality of information about stroke on the Romanian and Hungarian websites in terms of completeness and accuracy. Methods: The research was designed as an observational cross-sectional study. The sample included 25 Romanian and 25 Hungarian websites presenting information about stroke for the general public. General characteristics such as website ownership, main goal, website genre and medical approach were identified by the evaluators using a predetermined set of common instructions. The completeness and accuracy of the information were assessed by two independent assessors against a quality benchmark. Results: Overall, most of the websites were owned by private commercial companies (42%), had educational goal (66%), were designed as medical web-portals (46%) and had a conventional medicine approach (72%). Mean completeness score was 5.6 points (SD± 1.9) for Romanian sites and 4.1 points (SD ± 2.4) for Hungarian sites (p = 0.017). Mean accuracy score was 6.2 points (SD ± 1.1) for Romanian sites and 7.0 points (SD ± 0.7) for Hungarian sites (p = 0.02). Conclusions: The information about stroke on the Romanian and Hungarian websites had poor quality. Although we found statistically significant differences between the quality scores of the two language sub-samples and two site characteristics associated with significantly higher quality, the practical relevance of these findings for online health information seekers should be interpreted with caution.

International assessment on quality and content of internet information on osteoarthritis

OBJECTIVE

Osteoarthritis is one of the leading causes of global disability. Numerous studies have assessed the quality and content of online health information; however, how information content varies between multiple countries remains unknown. The primary objective of this study was to examine how the quality and content of online health information on osteoarthritis compares on an international scale.

METHODS

Internet searches for the equivalent of "knee osteoarthritis treatment" were performed in ten countries around the world. For each country, the first ten websites were evaluated using a custom scoring form examining: website type; quality and reliability using the DISCERN and Health-on-the-Net (HON) frameworks; and treatment content based on three international osteoarthritis treatment guidelines. Consistency of search results between countries speaking the same language was also assessed.

RESULTS

Significant differences in all scoring metrics existed between countries speaking different languages. Western countries scored higher than more eastern countries, there were no differences between the United States and Mexico in any of the scoring metrics, and HON certified websites were of higher quality and reliability. Searches in different countries speaking the same language had at least 70% overlap.

CONCLUSIONS

The quality of online health information on knee osteoarthritis varies significantly between countries speaking different languages. Differential access to quality, accurate, and safe health information online may represent a novel but important health inequality. Future efforts are needed to translate online health resources into additional languages. In the interim, patients may seek websites that display the HON seal.

Assessment of readability, quality and popularity of online information on ureteral stents

OBJECTIVE

To evaluate the quality and readability of online information on ureteral stents.

METHODS

Google.com was queried using the search terms "ureteric stent", "ureteral stent", "double J stent" and, "Kidney stent" derived from Google AdWords. Website popularity was determined using Google Rank and the Alexa tool. Website quality assessment was performed using the following criteria: Journal of the American Medical Association (JAMA) benchmarks, Health on the Net (HON) criteria, and a customized DISCERN questionnaire. The customized DISCERN questionnaire was developed by combining the short validated DISCERN questionnaire with additional stent-specific items including definition, placement, complications, limitations, removal and "when to seek help". Scores related to stent items were considered as the "stent score" (SS). Readability was evaluated using five readability tests.

RESULTS

Thirty-two websites were included. The mean customized DISCERN score and "stent score" were 27.1 ± 7.1 (maximum possible score = 59) and 14.6 ± 3.8 (maximum possible score = 24), respectively. A minority of websites adequately addressed "stent removal" and "when to seek medical attention". Only two websites (6.3%) had HON certification (drugs.com, radiologyinfo.org) and only one website (3.3%) met all JAMA criteria (bradyurology.blogspot.com). Readability level was higher than the American Medical Association recommendation of sixth-grade level for more than 75% of the websites. There was no correlation between Google rank, Alexa rank, and the quality scores (P > 0.05).

DISCUSSION

Among the 32 most popular websites on the topic of ureteral stents, online information was highly variable. The readability of many of the websites was far higher than standard recommendations and the online information was questionable in many cases. These findings suggest a need for improved online resources in order to better educate patients about ureteral stents and also should inform physicians that popular websites may have incomplete information.

Widespread use of internet, applications, and social media in the professional life of urology residents

INTRODUCTION

Digital media have revolutionized communication and information dissemination in healthcare. We aimed to quantify and evaluate professional digital media use among urology residents.

METHODS

We designed a 17-item survey to assess usage and perceived usefulness of digital media, as well as communication type and device type and distributed it via email to 143 Canadian and 721 German urology residents.

RESULTS

In total, 58 (41% response rate) residents from Canada and 170 (24% response rate) from Germany reported professional usage rates of 100% on the internet, 89% on apps, and 46% on social media (SoMe). For professional use, residents spent a median of 30 minutes per day on the internet, 10 minutes on apps, and 15 minutes on SoMe. 100% rated the internet, 89% apps, and 31% SoMe as useful for clinical practice. Most (94%) used digital media for communication with colleagues and 23% for communication with patients. Digital media use was allocated to desktop computers (55%) and mobile devices (45%). Canadian residents had higher usage rates of apps (96% vs. 86%; p=0.042) and SoMe (65% vs. 39%; p=0.002) and longer daily usage times for the internet, apps, and SoMe than German residents (p<0.001 each).

CONCLUSIONS

Digital media are an integral part of the daily professional practice of urology residents, reflected by high usage rates and perceived usefulness of the internet and apps, and the growing importance of SoMe. Urologists should strive to progressively exhaust the vast potential of digital media for academic and clinical practice.

Thoracic Surgery Information on the Internet: A Multilingual Quality Assessment

BACKGROUND

Previous data suggest that quality of Internet information regarding surgical conditions and their treatments is variable. However, no comprehensive analysis of website quality exists for thoracic surgery.

OBJECTIVE

The aim of this study was to quantify website quality in a multilingual setting using an international standard for assessment.

METHODS

Health On the Net (HON) principles may be applied to websites using an automated toolbar function. We used the English, French, Spanish, and German Google search engines to identify 12,000 websites using keywords related to thoracic conditions and procedures. The first 150 websites returned by each keyword in each language were examined. We compared website quality to assess for tertile (is the quality better in first, second, or third 50 websites returned) and language differences. A further analysis of the English site types was undertaken performing a comparative analysis of website provider types.

RESULTS

Overall, there are a considerable number of websites devoted to thoracic surgery: "lung cancer" returned over 150 million websites. About 7.85% (940/11,967) of websites are HON-accredited with differences by search term (P<.001) and tertiles (P<.001) of the first 150 websites, but not between languages. Oncological keywords regarding conditions and procedures were found to return a higher percentage of HON-accreditation. The percentage of HON-accredited sites was similar across all four languages (P=.77). In general, the first tertile contained a higher percentage of HON-accredited sites for every keyword.

CONCLUSIONS

Clinicians should appreciate the lack of validation of the majority of thoracic websites, with discrepancies in quality and number of websites across conditions and procedures. These differences appear similar regardless of language. An opportunity exists for clinicians to participate in the development of informative, ethical, and reliable health websites on the Internet and direct patients to them.

Health on the Net: Do Website Searches Return Reliable Health Information on Hemorrhoids and Their Treatment?

Objective:

To analyze the quality of health information on the Internet on hemorrhoids across 5 Western languages and perform a comparative analysis of website sponsors.

Summary of background data:

Hemorrhoids are a common condition affecting the hemorrhoid cushions of the anal canal. Many treatment options are available. Information on the Internet on hemorrhoids is considered variable, but there is little data analysis to support this. The World Health Organization's Health On the Net (HON) accredits medical and health websites based on a code of conduct and publishes a toolbar that aids identification of such accredited websites.

Methods:

Using the Google search engine (http://www.google.com, Google, Mountain View, California), searches were performed using 11 keywords related to hemorrhoids in English, French, German, Italian, and Spanish. Health On the Net accreditation was determined to assess quality website information. The first 150 websites in each language had their adherence to the HON principles analyzed, and English websites were analyzed to determine sponsorship source.

Results:

Of the 8250 websites analysed, 586 (7.1%) were found to HON-accredited. The rate of HON accreditation ranged from 2.0% (piles) to 10.0% (hemorrhoids), with higher-ranking results having higher rates of HON accreditation (P &lt; 0.001).

Conclusion:

There is a paucity of high-quality information on the Internet; however, the Google search algorithm prioritizes high-quality information in its web search results.

The Quality of Online Health-Related Information – an Emergent Consumer Health Issue

The Internet has become one of the main means of communication used by people who search for health-related information. The quality of online health-related information affects the users’ knowledge, their attitude, and their risk or health behaviour in complex ways and influences a substantial number of users in their decisions regarding diagnostic and treatment procedures.

The aim of this review is to explore the benefits and risks associated with using the Internet as a source of health-related information; the relationship between the quality of the health-related information available on the Internet and the potential risks; the multiple conceptual components of the quality of health-related information; the evaluation criteria for quality health-related information; and the main approaches and initiatives that have been implemented worldwide to help improve users’ access to high-quality health-related information.

Quality of Health Information on the Internet for Urolithiasis on the Google Search Engine

Purpose. To compare the quality of health information on the Internet for keywords related to urolithiasis, to assess for difference in information quality across four main Western languages, and to compare the source of sponsorship in these websites. Methods. Health On the Net (HON) Foundation principles were utilised to determine quality information. Fifteen keywords related to urolithiasis were searched on the Google search engine. The first 150 websites were assessed against the HON principles and the source of sponsorship determined. Results. A total of 8986 websites were analysed. A proportion of HON-accredited websites for individual search terms range between 2.5% and 12.0%. The first 50 websites were more likely to be HON-positive compared to websites 51–100 and 101–150. French websites searched were more likely to be HON-positive whereas German websites were less likely to be HON-positive than English websites. There was no statistically significant difference between the rate of HON-positive English and Spanish websites. The three main website sponsors were from government/educational sources (40.2%), followed by commercial (29.9%) and physician/surgeon sources (18.6%). Conclusions. Health information on most urolithiasis websites was not validated. Nearly one-third of websites in this study have commercial sponsorship. Doctors should recognise the need for more reliable health websites for their patients.

Trends in internet search activity, media coverage, and patient-centered health information after the FDA safety communications on surgical mesh for pelvic organ prolapse

INTRODUCTION

In July 2011, the US Food and Drug Administration (FDA) issued a safety communication regarding serious complications associated with surgical mesh for pelvic organ prolapse, prompting increased media and public attention. This study sought to analyze internet search activity and news article volume after this FDA warning and to evaluate the quality of websites providing patient-centered information.

METHODS

Google Trends™ was utilized to evaluate search engine trends for the term "pelvic organ prolapse" and associated terms between 1 January 2004 and 31 December 2014. Google News™ was utilized to quantify the number of news articles annually under the term "pelvic organ prolapse." The search results for the term "pelvic organ prolapse" were assessed for quality using the Health On the Net Foundation (HON) certification.

RESULTS

There was a significant increase in search activity from 37.42 in 2010 to 57.75 in 2011, at the time of the FDA communication (p = 0.021). No other annual interval had a statistically significant increase in search activity. The single highest monthly search activity, given the value of 100, was August 2011, immediately following the July 2011 notification, with the next highest value being 98 in July 2011. Linear regression analysis of news articles per year since the FDA communication revealed r² = 0.88, with a coefficient of 186. Quality assessment demonstrated that 42 % of websites were HON-certified, with .gov sites providing the highest quality information.

CONCLUSIONS

Although the 2011 FDA safety communication on surgical mesh was associated with increased public and media attention, the quality of relevant health information on the internet remains of poor quality. Future quality assurance measures may be critical in enabling patients to play active roles in their own healthcare.

Computer-assisted total knee arthroplasty marketing and patient education: an evaluation of quality, content and accuracy of related websites

BACKGROUND

The internet is increasingly being used as a resource for health-related information by the general public. We sought to establish the authorship, content and accuracy of the information available online regarding computer-assisted total knee arthroplasty (CA-TKA).

METHODS

One hundred fifty search results from three leading search engines available online (Google, Yahoo!, Bing) from ten different countries worldwide were reviewed.

RESULTS

While private physicians/groups authored 50.7 % of the websites, only 17.3 % were authored by a hospital/university. As compared to traditional TKA, 59.3 % of the websites claimed that navigated TKA offers better longevity, 46.6 % claimed accelerated recovery and 26 % claimed fewer complications. Only 11.3 % mentioned the prolonged operating room time required, and only 15.3 % noted the current lack of long-term evidence in support of this technology.

CONCLUSIONS

Patients seeking information regarding CA-TKA through the major search engines are likely to encounter websites presenting a narrow, unscientific, viewpoint of the present technology, putting emphasis on unsubstantiated benefits while disregarding potential drawbacks.

LEVEL OF EVIDENCE

Seeking health- and nutrition-related information on the Internet in a large population of French adults: results of the NutriNet-Santé study

The Internet has become a major source of health and nutrition information. Little is known about the type of consulted websites (institutional v. non-institutional) and the tendency to discuss with a healthcare professional (HCP) the information found on the Internet. The aim of this cross-sectional study was to investigate health- and nutrition-related Internet use in a large French population-based study. Data were collected in 2013 using self-administered, web-based questionnaires from 42 113 participants of the NutriNet-Santé study (mean age=51·2 years, 76 % women). Unconditional multivariate logistic regression analyses and χ 2 tests were used for comparisons. In total, 85·1 % of the subjects used the Internet to search for health and/or nutrition information, and 23·6 % used the Internet to read or post messages on health/nutrition forums. Only 16·0 % discussed with a HCP the information found online. This proportion was lower in subjects with lower educational level (OR 0·77; 95 % CI 0·72, 0·82) and lower computer skills (OR 0·70; 95 % CI 0·65, 0·76). In total, 8038 health/nutrition websites were cited, with institutional websites representing only 12·9 % of that number. Only one institutional website was present in the top 10. Older subjects (OR 1·49; 95 % CI 1·28-1·74), those with lower educational level (OR 2·08; 95 % CI 1·75, 2·50) and lower nutritional knowledge (OR 1·33; 1·12, 1·59) were more likely to cite non-institutional websites. This large population-based study showed that institutional websites were infrequently accessed and that a few participants discussed the information found online with their HCP. This particular trend was especially visible among individuals who were more vulnerable regarding misleading information. This supports the need to increase awareness of high-quality websites providing reliable health/nutrition information.

Evaluation of Quality and Readability of Health Information Websites Identified through India's Major Search Engines

Background. The available health information on websites should be reliable and accurate in order to make informed decisions by community. This study was done to assess the quality and readability of health information websites on World Wide Web in India. Methods. This cross-sectional study was carried out in June 2014. The key words “Health” and “Information” were used on search engines “Google” and “Yahoo.” Out of 50 websites (25 from each search engines), after exclusion, 32 websites were evaluated. LIDA tool was used to assess the quality whereas the readability was assessed using Flesch Reading Ease Score (FRES), Flesch-Kincaid Grade Level (FKGL), and SMOG. Results. Forty percent of websites (n = 13) were sponsored by government. Health On the Net Code of Conduct (HONcode) certification was present on 50% (n = 16) of websites. The mean LIDA score (74.31) was average. Only 3 websites scored high on LIDA score. Only five had readability scores at recommended sixth-grade level. Conclusion. Most health information websites had average quality especially in terms of usability and reliability and were written at high readability levels. Efforts are needed to develop the health information websites which can help general population in informed decision making.

The state and potential of social media in bladder cancer

INTRODUCTION

Social media sites and services have become intimately woven into our interpersonal communications and have begun to stake a visible place in healthcare. Disease-specific Twitter hashtags, online patient groups and participation by patients, practitioners and advocacy groups are emblematic of this new paradigm.

METHODS

A literature review and summary of resources and publications on bladder cancer and social media.

RESULTS

A majority of Western patients have access to and use the Internet for health information. Urologists and oncologists have used bladder-cancer-specific messaging at international meetings infrequently as compared to prostate and other non-urologic cancers. An active community does participate in online discussion, with differences between medical practitioners and patients/advocates. Advice is given with the aim of unifying this discussion.

Female urinary incontinence health information quality on the Internet: a multilingual evaluation

INTRODUCTION AND HYPOTHESIS

The quality of Internet information on female urinary incontinence is considered variable. No comprehensive analysis exists to support this. We compared the quality of current Internet information for common layperson terminology on female urinary incontinence across four Western languages and a comparative analysis of website sponsors.

METHODS

World Health Organization Health on the Net (HON) principles may be applied to websites using an automated toolbar function. We used the Google search engine; 10,200 websites were identified using keywords related to female urinary incontinence and treatments in English, French, German and Spanish. The first 150 websites in each language had HON principles examined, whilst a further analysis of site sponsorship was undertaken.

RESULTS

The total number of websites for each term is variable. "Female sling surgery" had the most websites with approximately 18 million, whereas "colposuspension" had the least with only 159,890 websites. Regardless of language, very few female urinary incontinence websites were HON accredited (p < 0.0001). Linguistically, French (18%) and English (16%) had the greatest percentage of HON-accredited sites. Tertiles (thirds) of the first 150 websites returned the higher percentage of HON-accredited websites (p < 0.0001). Websites were largely sponsored by physicians/surgeons.

CONCLUSIONS

The lack of validation of most female urinary incontinence websites should be appreciated by clinicians. Additionally, discrepancies exist in the quality and number of websites across conditions, languages and also between medical and alternative terms. Clinicians should participate in and encourage the development of informative, ethical and reliable health websites on the Internet and direct patients to them.

Decisional outcomes following use of an interactive web-based decision aid for prostate cancer screening

Informed decision-making tools are recommended for men considering prostate cancer screening. We evaluated the extent to which use of an interactive, web-based decision aid was associated with decisional and screening outcomes. Participants (N = 253) were 57 (7.0) years old and completed telephone interviews at baseline, 1 month, and 13 months post-baseline. Tracking software captured minutes spent on the website (median = 33.9), sections viewed (median = 4.0/5.0), testimonials viewed (median = 4.0/6.0), and values clarification tool (VCT) use (77.3 %). In multivariable analyses, all four website use variables were positively associated with increased knowledge (p's < 0.05). Complete VCT use and number of informational sections were positively associated with greater decisional satisfaction (p's < 0.05). Decisional conflict and screening behavior were not associated with measures of website use. Increased use of informational content and interactive elements were related to improved knowledge and satisfaction. Methods to increase utilization of interactive website components may improve informed decision-making outcomes.

A multilingual evaluation of current health information on the Internet for the treatments of benign prostatic hyperplasia

Purpose

To compare the quality of current Internet information on benign prostatic hyperplasia (BPH) and its surgical and medical managements across four Western languages and a comparative analysis of website sponsors. BPH Internet information quality is particularly relevant in an era of expanding, minimally invasive and surgical therapies. However, no comprehensive analysis exists.

Methods

World Health Organization Health on the Net (HON) principles may be applied to websites using an automated toolbar function. Using a search engine (www.google.com), 9,000 websites were assessed using keywords related to BPH and its medical and surgical treatment in English, French, German, and Spanish. The first 150 websites in each language had HON principles measured whilst a further analysis of site sponsorship was undertaken.

Results

Very few BPH websites had greater than ten per cent HON accredited with significant differences (P<0.001) based on terms used for BPH, its medical and surgical management. Tertiles (thirds) of the first 150 websites returned differences in accredited websites (P<0.0001). English language had most accredited websites. Odds ratios for different terms returning accredited websites also were significantly different across terms (P<0.001). Websites were largely commercially sponsored.

Conclusions

A lack of validation of most BPH sites should be appreciated with discrepancies in quality and number of websites across diseases, languages and also between medical and alternate terms. Physicians should participate in and encourage the development of informative, ethical and reliable health websites on the Internet and direct patients to them.

Trust in health information websites: A systematic literature review on the antecedents of trust

Health websites are important sources of information for consumers. In choosing websites, trust in websites largely determines which website to access and how to best utilize the information. Thus, it is critical to understand why consumers trust certain websites and distrust others. A systematic literature review was conducted with the goal of identifying the antecedents of trust in health information websites. After four rounds of screening process, 20 articles between 2000 and 2013 were harvested. Factors that determine trust are classified into individual difference antecedents, website-related antecedents, and consumer-to-website interaction-related antecedents. The most frequently studied antecedents were socio-demographics, information quality, appearance, and perceived reputation of the website. Each antecedent of trust are discussed in detail and future research directions are proposed.

A multilingual assessment of melanoma information quality on the Internet

This study aims to assess and compare melanoma information quality in Hungarian, Czech, and German languages on the Internet. We used country-specific Google search engines to retrieve the first 25 uniform resource locators (URLs) by searching the word "melanoma" in the given language. Using the automated toolbar of Health On the Net Foundation (HON), we assessed each Web site for HON certification based on the Health On the Net Foundation Code of Conduct (HONcode). Information quality was determined using a 35-point checklist created by Bichakjian et al. (J Clin Oncol 20:134-141, 2002), with the NCCN melanoma guideline as control. After excluding duplicate and link-only pages, a total of 24 Hungarian, 18 Czech, and 21 German melanoma Web sites were evaluated and rated. The amount of HON certified Web sites was the highest among the German Web pages (19%). One of the retrieved Hungarian and none of the Czech Web sites were HON certified. We found the highest number of Web sites containing comprehensive, correct melanoma information in German language, followed by Czech and Hungarian pages. Although the majority of the Web sites lacked data about incidence, risk factors, prevention, treatment, work-up, and follow-up, at least one comprehensive, high-quality Web site was found in each language. Several Web sites contained incorrect information in each language. While a small amount of comprehensive, quality melanoma-related Web sites was found, most of the retrieved Web content lacked basic disease information, such as risk factors, prevention, and treatment. A significant number of Web sites contained malinformation. In case of melanoma, primary and secondary preventions are of especially high importance; therefore, the improvement of disease information quality available on the Internet is necessary.

Use of the internet as a health information resource among French young adults: results from a nationally representative survey

BACKGROUND

The Internet is one of the main resources of health information especially for young adults, but website content is not always trustworthy or validated. Little is known about this specific population and the importance of online health searches for use and impact. It is fundamental to assess behaviors and attitudes of young people looking for online health-related information and their level of trust in such information.

OBJECTIVE

The objective is to describe the characteristics of Internet users aged 15-30 years who use the Web as a health information resource and their trust in it, and to define the context and the effect of such use on French young adults' behavior in relation to their medical consultations.

METHODS

We used the French Health Barometer 2010, a nationally representative survey of 27,653 individuals that investigates population health behaviors and concerns. Multivariate logistic regressions were performed using a subsample of 1052 young adults aged 15-30 years to estimate associations between demographics, socioeconomic, and health status and (1) the use of the Internet to search for health information, and (2) its impact on health behaviors and the physician-patient relationship.

RESULTS

In 2010, 48.5% (474/977) of Web users aged 15-30 years used the Internet for health purposes. Those who did not use the Internet for health purposes reported being informed enough by other sources (75.0%, 377/503), stated they preferred seeing a doctor (74.1%, 373/503) or did not trust the information on the Internet (67.2%, 338/503). However, approximately 80% (371/474) of young online health seekers considered the information found online reliable. Women (P<.001) and people with higher sociocultural positions (OR 0.5, 95% CI 0.3-0.9 and OR 0.4, 95% CI 0.2-0.7 for employees and manual workers, respectively, vs individuals with executive or manager positions) were more likely to use the Internet for health purposes. For a subsample of women only, online health seeking was more likely among those having a child (OR 1.8, 95% CI 1.1-2.7) and experiencing psychological distress (OR 2.0, 95% CI 1.0-4.0). Finally, for online health seekers aged 15-30 years, one-third (33.3%, 157/474) reported they changed their health behaviors (eg, frequency of medical consultations, way of taking care of one's own health) because of their online searches. Different factors were associated with different outcomes of change, but psychological distress, poor quality of life, and low income were the most common.

CONCLUSIONS

The Internet is a useful tool to spread health information and prevention campaigns, especially to target young adults. Young adults trust online information and consider the Internet as a valid source of health advice. Health agencies should ensure the improvement of online health information quality and the creation of health-related websites and programs dedicated to young adults.

Do cancer-specific websites meet patient's information needs?

OBJECTIVE

To evaluate commonly used cancer websites' information provision, we developed and applied an Information Comprehensiveness Tool to breast and prostate cancer websites.

METHODS

We first collated questions from a systematic literature review on patient information needs. We then classified the questions in terms of spectrum of care, theme, and nature of question. "Breast cancer" and "prostate cancer" were typed into Google, and websites listed on the first page of results were selected. Two researchers, blind to each others' scores, assessed the same websites using the coding system. Each question was scored on a 3-point scale as not (0%), partially (50%) and fully (100%) answered by two researchers. Average scores were calculated across all questions. Inter-rater reliability was assessed.

RESULTS

We identified 79 general, 5 breast, and 5 prostate cancer questions. Inter-rater reliability was good, with an intraclass coefficient of 0.756 (95% CIs 0.729-0.781). 17 questions were not answered thoroughly by any website. Questions about "future planning", "monitoring", and "decision-making" were discussed least. Biomedical questions scored highest.

CONCLUSIONS

More comprehensive information needs to be provided on breast and prostate cancer websites.

PRACTICE IMPLICATIONS

This ICT can improve cancer information online and enable patients to engage more actively regarding their information needs.

The internet's role in HPV vaccine education

The internet is the second most popular source, after healthcare providers, of information regarding human papillomavirus (HPV). These online searches usually begin with the user entering generic terms in the search engine, and then reading the first few results that the engine returns. Unfortunately, research shows that much of this information obtained about the HPV vaccine is inaccurate and incomplete. In this review, we summarize the literature pertaining to online information concerning the HPV vaccine and review concerns related to obtaining online medical information. Finally, we propose possible solutions medical providers can employ in their everyday practice to help their patients obtain accurate information through their online searches.
