EMBASE has recently released an enhancement to improve the coverage of drug terminology in Emtree. Changes may affect how some explosion searches are executed, primarily in cases where high-level terms in the Emtree structure are used. Emtree in 2012 is divided into 14 facets, from Anatomical concepts to Types of article or study.
These are the facets in which most changes can be found:
- Anatomical concepts
- Biological functions
- Diseases
- Organisms
- Procedures, parameters and devices
- Psychological and psychiatric phenomena
For a comprehensive list of these changes and guidance as to why quantitatively different results may be expected, please click here.
Other improvements include:
- 952 new drug terms and 991 non-drug terms have been added.
- Coverage of drug terminology in Emtree is broader and more comprehensive: Emtree now covers all new International Non-Proprietary Names (INNs) for drugs registered with the World Health Organization (WHO), as well as all US Adopted Names and NDAs (New Drug Approvals) listed by the Food & Drug Administration (FDA) and European Medicines Agency (EMA) until mid-November 2011. Trade names belonging to major pharmaceutical companies are also covered.
- All MeSH (Medical Subject Heading) terms introduced by the National Library of Medicine (NLM) in 2012 are included in Emtree 2012, so that Emtree terminology is now fully in synchrony with MeSH updates.
