Last week at TAM8 some SBM colleagues (David Gorski, Kimball Atwood, Harriet Hall, Rachel Dunlop) and I gave two workshops on how to find reliable health information on the web. As part of my research for this talk I came across a recent and interesting study that I would like to expand upon further – Quality and Content of Internet-Based Information for Ten Common Orthopaedic Sports Medicine Diagnoses.
The fact that the article focuses on orthopedic diagnoses is probably not relevant to the point of the article itself, which was to assess the accuracy of health information on the web. They looked at 10 orthopedic diagnoses and searched on them using Google and Yahoo, and then chose the top results. They ultimately evaluated 154 different sites with multiple reviewers for quality of content and also for their HON rating.
For background, the HON rating comes from an independent organization, the Heath on the Net Foundation, that rates health care sites on a number of criteria. These include assessment of how authoritative the sources are, the level of transparency, and if opinions expressed are justified with evidence and references. While generally reasonable, the HON assessment does not necessarily involve a thorough assessment of the quality of the science on a given website, and many sites with what I would consider dubious information have earned the HON seal of approval.
