UpToDate covers more than 7,700 topics in 14 medical specialties and includes more than 80,000 pages of text, graphics, links to Medline abstracts, more than 260,000 references, and a drug database. Its physician editors and authors review and update the content continuously. An updated version of UpToDate is released every four months.
UpToDate includes treatment recommendations based on the best medical evidence. Recommendations are kept current as new studies are released and practices change. They are now grading their recommendations, so users can assess the strength and the quality of the evidence more quickly. For more details, please see the editorial policy.UpToDate is evidence-based and uses a literature-driven updating system; more than 430 journals are monitored by editors and authors, and anytime something of importance is published, it is incorporated into the program. The key word here is "incorporated." UpToDate is not a journal watch. New studies are not simply added, but rather they are placed in the context of what has already been published in that field.
