A medical journal is a peer-reviewed scientific journal that communicates medical information to physicians and other health professionals. Journals that cover many medical specialties are sometimes called general medical journals.
The first medical journals were general medical journals, and were established in the late 18th century; specialty-specific medical journals were first introduced in the early 20th century. The first medical journal to be published in the United Kingdom was Medical Essays and Observations, established in 1731 and published in Edinburgh; the first to be published in the United States was The Medical Repository, established in 1797.
Richard Smith, the former editor of the medical journal the BMJ, has been critical of many of the aspects of modern-day medical journal publishing.
