ABSTRACT This study evaluated the readability, accessibility, usability, and reliability of vascular surgery information on the Internet in the English language.
The Google, Yahoo, and MSN/Bing search engines were searched for "carotid endarterectomy," "EVAR or endovascular aneurysm repair," and "varicose veins or varicose veins surgery." The first 50 Web sites from each search engine for each topic were analyzed. The Flesch Reading Ease Score and Gunning Fog Index were calculated to assess readability. The LIDA tool (Minervation Ltd, Oxford, UK) was used to assess accessibility, usability, and reliability.
The Web sites were difficult to read and comprehend. The mean Flesch Reading Ease scores were 53.53 for carotid endarterectomy, 50.53 for endovascular aneurysm repair, and 58.59 for varicose veins. The mean Gunning Fog Index scores were 12.3 for carotid endarterectomy, 12.12 for endovascular aneurysm repair, and 10.69 for varicose veins. The LIDA values for accessibility were good, but the results for usability and reliability were poor.
Internet information on vascular surgical conditions and procedures is poorly written and unreliable. We suggest that health professionals should recommend Web sites that are easy to read and contain high-quality surgical information. Medical information on the Internet must be readable, accessible, usable, and reliable.

    ABSTRACT: Study Design. A readability and quality-control Internet-based study using recognized quality scoring systemsObjective. To assess the readability and quality of Internet information relating to Cauda Equina Syndrome accessed through common search engines.Summary of Background Data. Access to Health-related Internet information has increased dramatically over the past decade. A significant proportion of this information has been demonstrated to be set at too high a level for general comprehension. Despite this, searching for Health-related information is now the third most popular online activity.Methods. A total of 125 Cauda Equina Syndrome websites were analysed from the five most popular Internet search engines; Google, Bing, Yahoo, Ask and AOL. Website Authorship was classified: Academic, Physician, Medico-legal, Commercial or Discussion/Social media. Readability of each website was assessed using the Flesch Reading Ease Score, the Flesch-Kincaid grade level and the Gunning Fog Index. Quality was calculated using the DISCERN instrument and JAMA benchmark criteria. The presence of HON-code certification was also assessed.Results. 52 individual websites were identified and assessed. The majority of websites were Academic or Physician compiled 53.8% (28/52), however a significant minority were Medico-legal related 19.2% (10/52). Just 13.5% (7/52) of websites were at or below the recommended 6 grade readability level. HON-code certified websites achieved significantly greater DISCERN (P = 0.0006) and JAMA (P = 0.0002) scores.Conclusion. Internet information relating to Cauda Equina Syndrome is of variable quality and largely set at an inappropriate readability level. Given this variability in quality, healthcare providers should direct patients to known sources of reliable, readable online information. Identification of reliable sources may be aided by known markers of quality such as HON-code certification.

    ABSTRACT: In many countries, the decline in smoking prevalence has coincided with a growing concentration of smoking among people with lower socioeconomic status (SES). This concentration may reflect the social differentiation of risk perceptions. We investigated the factors associated with risk perception and fear of cancer, paying particular attention to SES indicators and health information seeking.

    ABSTRACT: Objective To evaluate orthodontic practice websites for the reliability of information presented, accessibility, usability for patients and compliance to General Dental Council (GDC) regulations on ethical advertising.Setting World Wide Web.Materials and methods The term 'orthodontic practice' was entered into three separate search engines. The 30 websites from the UK were selected and graded according to the LIDA tool (a validated method of evaluating healthcare websites) for accessibility, usability of the website and reliability of information on orthodontic treatment. The websites were then evaluated against the GDC's Principles for ethical advertising in nine different criteria.Results On average, each website fulfilled six out of nine points of the GDC's criteria, with inclusion of a complaints policy being the most poorly fulfilled criteria. The mean LIDA score (a combination of usability, reliability and accessibility) was 102/144 (standard deviation 8.38). The websites scored most poorly on reliability (average 43% SD 11.7), with no single website reporting a clear, reliable method of content production. Average accessibility was 81% and usability 73%.Conclusions In general, websites did not comply with GDC guidelines on ethical advertising. Furthermore, practitioners should consider reporting their method of information production, particularly when making claims about efficiency and speed of treatment in order to improve reliability.
