Data Changes
On January 29, 2010, the U.S. National Library of Medicine (NLM) and the U.S. Department of Veterans Affairs, Veterans Health Administration (VHA) signed an agreement making it possible for the VHA National Drug File - Reference Terminology (NDF-RT) to be included as a source vocabulary in RxNorm. NDF-RT is a terminology used to code clinical drug properties, including mechanism of action, physiologic effect, and therapeutic category. It is an extension of the VHA National Drug File (VANDF), another RxNorm source vocabulary. Beginning with the RxNorm release on Monday, June 7th, NDF-RT data will be included in the RxNorm monthly releases. It will continue to be released as a source in Unified Medical Language System (UMLS) as well.
Users should note that a minor change has been made to the MySQL and Oracle database load scripts that accompany the RxNorm data files in the release zip file. The "RXCUI not null constraint" has been removed from the RXNSAT ddl in the "RxNormDDL.sql" file for Oracle (scripts/oracle directory) and in the "Table_scripts_mysql_rxn.sql" file for MySQL (scripts/mysql directory) to accommodate "RXCUI null" cases for NDFRT relationship attributes. This change did not affect the OCD RRF files.
For more information specific to NDF-RT, please contact Michael Lincoln at the VHA (michael.lincoln@va.gov). Questions about the RxNorm representation of NDF-RT should be sent to: rxnorminfo@nlm.nih.gov.
