STN(R) Reflects Second Update to Emtree(R) Thesaurus for 2018

28. May 2018

The second Emtree thesaurus release for 2018 is now available within Embase(TM). Now totaling 81,003 preferred terms and over 355,000 synonyms, this new version includes 1,019 more preferred terms compared to the previous version released January 2018.

Of the 1,104 new terms (which includes 85 replacement terms and synonym promotions), 189 are drug terms allowing you to keep up-to-date with the latest developments in the terminology of pharmacology and biomedicine. Part of the synonym enrichment is the addition of 3,673 medical device trade names.

Please review and update your Alert (SDI) strategies or saved searches. Any of the replaced terms must be updated with the new terms to ensure comprehensive retrieval.
