Jane Falconer, a medical librarian, wrote a real interesting blog post. She writes about the importance of reliable information to front line health professionals and stresses the importance of systematic reviews that are conducted according to recognised and tested methodologies.
The big problem: what to include in the systematic review, and what to exclude in projects like are PRISMA and Cochrane. This is the same problem we face when we seek sources for Wikipedia articles and, the Wikimedia solution to provide sources is the "The Wikipedia Library Card Platform".
Cochrane and the Wikimedia Foundation are partners and one scenario I can see is one where this partnership is intensified. When Cochrane shares its results with Wikidata, they can have all the data of Wikidata anyway the quality and the relevance of the Wikidata data improves. When Cochrane volunteers may share the Library Card Platform, it would bring a major contribution to the volunteers at Cochrane. The relevance of the data at Wikidata will improve substantially. This in turn will help us verify the content of medical information and the quality of the sources in all our Wikipedias.
