NEW Emtree Update:

February 2012 Release: Improvements on the coverage of drug terminology in Emtree.

The next Embase release will be on Tuesday the 28th of February. This release is focused on delivering significant improvements on the coverage of drug terminology in Emtree. (see below)

How will these key changes on the Emtree structure affect you?

Although the list of changes appears extensive, the consequences are unlikely to be large for most users.

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. This is one facet less than in 2011.

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

What are the main benefits of these improvements?

Terminology Improvements

- 952 new drug terms and 991 non-drug terms have been added (compared with Emtree 2011). This represents a growth rate significantly greater than in previous years, and especially reflects the attention paid to new drug terminology.

- Coverage of drug terminology in Emtree is broader and more comprehensive than ever: 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 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.

Tree structure Improvements

- Key facets are now organized to ensure that users have a better overview of the overall Emtree structure.

- Terminology used for explosion searches has been updated to be more self explanatory and simpler to use.
