General
Questionnaires, Ratings, and Scales (QRS) are very common in clinical trial protocols. CDISC has published many supplements to provide users on how to structure the QRS data in a standard format using SDTM. Users can view the normative information regarding relevant CDISC Controlled Terminology (CT) codelists & terms, and how they map and apply in SDTM datasets. CDISC Library provides users a machine-readable version of this normative information, such as the exact CT term to use in the SDTM --CAT variable, an item's --TEST and --TESTCD, one-to-one pairing of --TEST and --TESTCD, ordering of items, and lastly, response codelists & terms for each applicable item.
For full details about QRS Supplements to SDTMIG, visit https://www.cdisc.org/foundational/qrs.
Metadata for these QRS loaded are listed below, with short name (--CAT) in parentheses:
- 6 Minute Walk Test (SIX MINUTE WALK)
- Clinical Global Impression (CGI)
- Patient Global Impression (PGI)
A separate maintenance release after 2021-06-28 will include:
- Combat Exposure Scale (CES)
- Eastern Cooperative Oncology Group Performance Status (ECOG)
In this short video is a walkthrough of how to access QRS metadata using the Data Standards Browser and download an Excel export.
These are generic API query templates for requesting QRS metadata:
/mdr/products/QrsInstrument /mdr/qrs/instruments/{instrument}/versions/{version} /mdr/qrs/instruments/{instrument}/versions/{version}/responseGroups /mdr/qrs/instruments/{instrument}/versions/{version}/responseGroups/{responseGroup} /mdr/qrs/instruments/{instrument}/versions/{version}/items /mdr/qrs/instruments/{instrument}/versions/{version}/items/{item} /mdr/root/qrs/instruments/{instrument}
Line #1: Gets a list of all QRS instruments loaded into CDISC Library.
