Embase Reload Completed

Dear Ovid Embase Customer:

The Embase (EMED) Database has been reloaded to implement the new 2023.02 Thesaurus Tool.

Changes in the new thesaurus

Emtree terms improvement:
651 new terms (including 26 replacement terms and promoted synonyms) have been added to Emtree as preferred terms in version September 2023:

  • 52 drug terms (terms assigned to the Chemicals and Drugs facet).
  • 599 non-drug terms (terms not assigned as Chemicals and Drugs).

Emtree Terms Changed in September 2023:

  • 26 terms (21 drug terms and 5 non-drug terms) have been replaced by 26 different terms in September 2023 (5 drug terms and 21 non-drug terms).
  • Of these, 24 terms (4 drug terms and 20 non-drug terms) are new (e.g. new generic names for drug chemical names) and have been assigned a 2023 creation date; the remaining 2 replacement terms (1 drug term and 1 non-drug term) were already present in Emtree.
  • No drug terms were replaced by a non-drug term, and no non-drug terms were replaced by a drug term. No preferred terms were deleted.
