The 2020 MeSH (Medical Subject Headings) vocabulary was evaluated for inclusion in the Classification index. Several additions and changes were made to the Index and Schedules based on this review. All main index headings are now linked to the 2020 vocabulary in the MeSH Browser. A mini-systematic review of the W 775-867 Medicolegal Examination section was conducted. Additional minor updates were made to the Index and Schedules.

  • 59 index main headings added (49 from 2020 MeSH)
  • 155 index entries modified
  • 5 index headings deleted
  • 11 class numbers added (visit Class Numbers Added and Canceled (Current Edition))
  • 338 class number captions or notes modified

More detailed information about the scope of the 2020 winter edition is available. The 2020 summer version will be published in mid-to-late August 2020.
