Abstract
Reverse shoulder arthroplasty (RSA) is increasingly performed recently. The patients seeking internet as a source of information may get misleading and a false sense of expectation. This study aimed at analysing patient information on internet and establish list of available quality websites to safely recommend to the patients.
The study analysed 310 websites from 10 top search engines exploring the quality of patient information using an assessment tool. Search engines used were metasearch (Metacrawlers and Mamma), general search (Google, Altavista, Yahoo, MSN, AOL, Lycos) and health search engines (Medhunt and Excite Health). The study was undertaken by two independent researcher over a four-week period in November 2011. Each Website was evaluated according to RSA-specific content using a point value system with shoulder disease and surgery specific key words on an ordinal scale. Adequacy of the content was analysed in regard with description of diagnosis, procedure, alternate options, postoperative protocol, complications and prognosis.
Excluding the repetitions 104 websites were analysed for accessibility, relevance, authenticity, adequacy of patient information and accountability. The median time since update was 12 months. More than 90% of the websites were found to be of poor quality. Only 25% sites targeted mainly people with shoulder problems. 8% of websites were from non profit organisations. Most of these websites were promoting either their service 80 (76%) or some product 12 (11%). The strength of association between two reviewers was very high (r = 0.899). Intra-rater reliability was significant (r = 0.955) with p level < 0.01. The reading level of most of websites were too high for average consumers.
There is need for government organizations and professional societies to regulate the information provided by Internet. Until long-term data are available, patients should be warned when using the Internet as a source for health care information.
