NEW: MeSH terms for 2019 include Systematic Review as a publication type

As usually happens at this time of year, the National Library of Medicine (NLM) update the MeSH headings used to index their Medline/PubMed database. Full details can be found on the NLM Technical Bulletin, 425. Changes which may be of interest to LSHTM researchers have been highlighted below.

Changes to publication types

The NLM have made additions to their publication types, including adding a systematic review heading.

The new publication types which will be most useful for LSHTM researchers are:

  • Systematic review
  • Clinical Trial Protocol
  • Clinical Trial, Veterinary
  • Observational Study, Veterinary
  • Preprint

Usually the NLM does not retrospectively re-index existing Medline records with new MeSH terms. However, an exception has been made for 2019 and systematic reviews have been retrospectively indexed with the ‘Systematic Review’ publication type.

There are also new MeSH headings which index methodological papers about publication types, by indexing them under the following MeSH headings:

  • Clinical trial protocols as topic
  • Clinical trials, veterinary as topic
  • Forms as topic
  • Preprints as topic
  • Systematic Reviews as topic

There is also a new MeSH heading for Gray Literature.
