Changes Coming in December 2015


Questionnaires, Ratings, and Scales (QRS) Terminology

Keeping the QRS codelists separate from the SDTM codelists was a decision based on the limits of excel spreadsheets.   This decision has been reversed and we will be merging the QRS codelists into the SDTM publication at the end of 2015.  The only content change will be in the codelist long name.  Currently the long name starts with QS-, or FT-, or CC-.  This prefix will be removed from the codelist long name only. 


CDISC Clinical Data Element

CDISC's Clinical Data Element Glossary contains terms that were created to support an early version of a cardiovascular therapeutic area user guide that was ultimately left unpublished.  The Clinical Data Element Glossary has been deprecated, and will be retired at the end of 2015.

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.

As of 25 September 2015 the SDTM, SEND, and Questionnaires, Ratings, and Scales (QRS) Controlled Terminology files have been updated on NCI/EVS. The dates of the new files are 2015-09-25. These terminology files replace all older SDTM, SEND, and QRS terminology files and include terms from Review Package 23. There are approximately 66 new QRS terms and 239 new terms across SDTM and SEND files.


The Clinical Outcome Assessment (COA) Terminology file is now changed to Questionnaires, Ratings, and Scales (QRS) Terminology on the NCI/EVS website and contains new links.
