          Abstract

          Background: Transparency is an indicator of trustworthiness and quality of health information about eye diseases on the Internet. Methods: 20 websites that contained information about eye diseases aimed at the general public were evaluated. A modified Afgis (Aktionsforum Gesundheitsinformationssystem/action forum health information system) project transparency checklist was used. Results: On average, 6.15 ± 1.68 criteria were fulfilled. All websites maintained separation between advertising and editorial content. Between 80 and 90% of the websites studied contained complete information about the provider, aims and target audience, and feedback from users. The criteria for privacy were met by 70% of websites, 40% met those for currency of content and data, 35% those for methods of quality assurance, 15% those for financing and sponsoring and 0% met the requirements for authors and sources of information. Conclusion: Visually impaired people benefit from transparency, because this facilitates accessibility to web-based health information. Hence, websites containing health information related to eye diseases should meet the demands of transparency.

          Examination of instruments used to rate quality of health information on the internet: chronicle of a voyage with an unclear destination.

          Anna Gagliardi, Alejandro Jadad (2002)
          This study updates work published in 1998, which found that of 47 rating instruments appearing on websites offering health information, 14 described how they were developed, five provided instructions for use, and none reported the interobserver reliability and construct validity of the measurements. All rating instrument sites noted in the original study were visited to ascertain whether they were still operating. New rating instruments were identified by duplicating and enhancing the comprehensive search of the internet and the medical and information science literature used in the previous study. Eligible instruments were evaluated as in the original study. 98 instruments used to assess the quality of websites in the past five years were identified. Many of the rating instruments identified in the original study were no longer available. Of 51 newly identified rating instruments, only five provided some information by which they could be evaluated. As with the six sites identified in the original study that remained available, none of these five instruments seemed to have been validated. Many incompletely developed rating instruments continue to appear on websites providing health information, even when the organisations that gave rise to those instruments no longer exist. Many researchers, organisations, and website developers are exploring alternative ways of helping people to find and use high quality information available on the internet. Whether they are needed or sustainable and whether they make a difference remain to be shown.

              Accessibility, nature and quality of health information on the Internet: a survey on osteoarthritis.

              Robert S. Green, D Ilic, S Maloney (2005)
              This study aims to determine the quality and validity of information available on the Internet about osteoarthritis and to investigate the best way of sourcing this information. Keywords relevant to osteoarthritis were searched across 15 search engines representing medical, general and meta-search engines. Search engine efficiency was defined as the percentage of unique and relevant websites from all websites returned by each search engine. The quality of relevant information was appraised using the DISCERN tool and the concordance of the information offered by the website with the available evidence about osteoarthritis determined. A total of 3443 websites were retrieved, of which 344 were identified as unique and providing information relevant to osteoarthritis. The overall quality of website information was poor. There was no significant difference between types of search engine in sourcing relevant information; however, the information retrieved from medical search engines was of a higher quality. Fewer than a third of the websites identified as offering relevant information cited evidence to support their recommendations. Although the overall quality of website information about osteoarthritis was poor, medical search engines may provide consumers with the opportunity to source high-quality health information on the Internet. In the era of evidence-based medicine, one of the main obstacles to the Internet reaching its potential as a medical resource is the failure of websites to incorporate and attribute evidence-based information.
