The document summarizes a study that assessed the quality of 52 medical wikis using criteria from the Health Summit Working Group. It found that wikis with editorial review processes scored higher on quality. Wikis without controls were poorer on criteria like credibility, content, disclosure, and caveats. The study concluded that peer review and contributor qualifications are necessary to ensure quality of health information, even if it limits the open Web 2.0 model. The MIGHEALTHNET wiki example confirmed this, as an open structure led to issues like redundancy and completeness.
