2008AA - Current UMLS Release

What's New

Metathesaurus^®:

4 new sources were added:  ICNP (International Classification for Nursing Practice), LNC_Braden (The Braden Scale for Predicting Pressure Sore Risk), LNC_FLACC (The Faces, Legs, Activity, Cry, and Consolability (FLACC) Scale), and LNC_WHO (Patient Monitoring Guidelines for HIV Care and Antiretroviral Therapy (ART)).

47 sources were updated, including MeSH, CPT, LOINC, SNOMED CT in English and Spanish, and RxNorm. For a complete list of updated sources see http://www.nlm.nih.gov/research/umls/updated_sources.html.

LOINC currently contains a small amount of proprietary data from six copyrighted sources. NLM extracts this data and represents it as six separate sources in the Metathesaurus. These are: LNC_MDS, LNC_OASIS, LNC_PHQ_9, LNC_Braden, LNC_FLACC and LNC_WHO. 

MetamorphoSys:

The RxNorm Filter has been removed from MetamorphoSys. Users are advised to download the RxNorm files separately from the UMLSKS or select RxNorm from the Source List tab.

The RRF Browser now includes a Restrict Searches and Views option that allows users to highlight terms from specific sources, semantic types, or content views. A tutorial on the use of the new Restrict Searches and Views option can be found in the New Users Guide (http://www.nlm.nih.gov/research/umls/new_users.html).

Users who are new to the UMLS are encouraged to review the New Users Guide to the UMLS available at http://www.nlm.nih.gov/research/umls/new_users.html. This guide includes online demonstrations, step-by-step instructions and a link to UMLS training materials.

SPECIALIST Lexicon and Lexical Tools:

LVG has been updated for 2008 and includes new and enhanced flow components.  Documentation is available at: http://lexsrv3.nlm.nih.gov/SPECIALIST/Projects/lvg/current/index.html.

There are no known problems for the 2007AC release. Please send any issues or concerns to custserv@nlm.nih.gov.
