  Patients are increasingly seeking health information on the Internet, but to the best of our knowledge, this has not been previously studied in haematology. We aimed to characterise online healthPatients are increasingly seeking health information on the Internet, but to the best of our knowledge, this has not been previously studied in haematology. We aimed to characterise online health information use and associated variables among adult outpatients in our tertiary-care centre in Flanders, Belgium. During a 6-week period, we distributed 477 anonymous self-administered questionnaires and received 451 (response rate 94.5%), of which 444 (93.1% of total) contained information on Internet use for health information, the primary outcome. Two hundred and thirty-two respondents (52.3%) had ever sought any health information online, and 187 (33.1%) conducted searches pertaining to their haematological disease in the past year. The latter was independently associated with younger age and a higher level of education in multivariate analysis. Internet users ranked the Internet higher and other resources lower as health information resources. Among Internet users, 196 (89.5%) would be interested in a list of reliable websites about their disease. Patients reported positive and negative aspects of online health information-seeking; it increased anxiety in some while it stimulated coping in others. We conclude that haematological patients commonly use the Internet for health information and report both positive and negative aspects of using this medium.

Wikipedia, a collaboratively written Web-based encyclopedia, has become the dominant online reference work. It is usually among the top results of search engine queries, including when medical information is sought. Since April 2004, editors have formed a group called WikiProject Medicine to coordinate and discuss the English-language Wikipedia's medical content. This paper, written by members of the WikiProject Medicine, discusses the intricacies, strengths, and weaknesses of Wikipedia as a source of health information and compares it with other medical wikis. Medical professionals, their societies, patient groups, and institutions can help improve Wikipedia's health-related entries. Several examples of partnerships already show that there is enthusiasm to strengthen Wikipedia's biomedical content. Given its unique global reach, we believe its possibilities for use as a tool for worldwide health promotion are underestimated. We invite the medical community to join in editing Wikipedia, with the goal of providing people with free access to reliable, understandable, and up-to-date health information.

We assessed whether article quality influenced this ranking. The authors tested whether traffic to Wikipedia coincided with epidemiological trends and news of emerging health concerns, and how it compares to MedlinePlus.MeasurementsCumulative incidence and average position of Wikipedia® compared to other Web sites among the first 20 results on general Internet search engines (Google®, Google UK®, Yahoo®, and MSN®), and page view statistics for selected Wikipedia articles and MedlinePlus pages.ResultsWikipedia ranked among the first ten results in 71–85% of search engines and keywords tested. Wikipedia surpassed MedlinePlus and NHS Direct Online (except for queries from the latter on Google UK), and ranked higher with quality articles. Wikipedia ranked highest for rare diseases, although its incidence in several categories decreased. Page views increased parallel to the occurrence of 20 seasonal disorders and news of three emerging health concerns. Wikipedia articles were viewed more often than MedlinePlus Topic (p = 0.001) but for MedlinePlus Encyclopedia pages, the trend was not significant (p = 0.07–0.10).ConclusionsBased on its search engine ranking and page view statistics, the English Wikipedia is a prominent source of online health information compared to the other online health information providers studied.
