UpToDate & DynaMed

UpToDate, founded in 1992 and now part of Wolters Kluwer, pioneered the structured, continuously updated, peer-reviewed clinical-topic article. DynaMed, EBSCO's competitor in the space, follows a similar model with a stronger emphasis on explicit evidence grading. Both are organised around clinical decisions — diagnosis, treatment, prognosis, follow-up — for individual diseases and presentations, rather than around the literature itself.

For researchers, they're useful as a fast on-ramp to the consensus picture of a disease before diving into primary literature, and for cross-checking how a condition is currently managed in practice. Most academic medical centres license one or both; remote access usually requires institutional credentials.
