Controlled Terminology

CDISC Controlled Terminology is the set of CDISC-developed or CDISC-adopted standard expressions (values) used with data items within CDISC-defined datasets. The CDISC Terminology Team, in collaboration with the National Cancer Institute's Enterprise Vocabulary Services (EVS), supports the controlled terminology needs of all CDISC Foundational Standards (SDTM (Drugs and Devices), CDASH, ADaM, SEND) and all CFAST disease/therapeutic area standards. 

Current Controlled Terminology Release

September 30, 2016

Alert:  In the recent terminology publication of 30Sep2016, the newly published test code/test name terms are missing the default synonyms that are identical to the test name values.  This will be corrected in the publication of 16Dec2016 (but we will evaluate making the update sooner).  We apologize for any inconvenience this may have caused.

CDISC Controlled Terminology is maintained and distributed as part of NCI Thesaurus on an NCI File Transfer Protocol (FTP) site and is available for direct download on this page.  It is available in Excel, text, odm.xml, pdf, html and OWL/RDF formats. 

New requests or changes to existing terminology can be accessed through the NCI/EVS New Term Request Page and is available for direct download on this page.

As of 30 September 2016 the SDTM, ADaM, CDASH, and SEND Controlled Terminology files have been updated on NCI/EVS. The dates of the new files are 2016-09-30.  These terminology files replace all older SDTM, ADaM, CDASH, and SEND files and include terms from Review Package 27. There are approximately 158 new QRS terms and 207 new terms across SDTM, ADaM, CDASH, and SEND.
