Team Characteristics

The CDISC Controlled Terminology program consists of more than 10 active 15 active terminology teams responsible for developing terminology to support Foundational Standards and Therapeutic AreasCDISC foundational standards and therapeutic areas. These teams consist of terminology and subject matter experts, data and standards personnel from pharmaceutical, biologics and device companies, CROs, academic researchers, and personnel from regulatory authorities.

The US National Cancer Institute's Enterprise Vocabulary Services (NCI-EVS) provides

team leadership and management, adherence to terminology best practices, definition writing, subject matter expertise, terminology publication, and maintenance. CDISC terminology is incorporated as part of the NCI Thesaurus (ncit.nci.nih.gov).

Team Mission

Primary Objectives

• Support the terminology needs of CDISC foundational standards and therapeutic area standards across the clinical study lifecycle.
• Support the terminology needs of the CDISC user community through the new term request webpage.
• Focus on standard terminology codelist development, management and publication, publication, and maintenance. Develop submission values and definitions for each term.
• Harmonize across CDISC models and with pre-existing vocabulary initiatives.
• Continually improve the terminology process to keep pace with the development of CFAST Therapeutic Area Standards and other CDISC foundational standards.

 Adopt…Adapt…Develop Philosophy

Terminology Development Cycle

The CDISC terminology teams follow a quarterly process for CDISC terminology updates. The CDISC Glossary team follows a yearly update cycle. New term requests and requests for changes come in through the CDISC new term request system (powered by EVS) and the CDISC terminology teams develop each request in the order received. Therapeutic area requests have priority over general user requests. At a pre-determined timepoint, the package is closed and sent out for a four-week open, public review. Public review comments are addressed by CDISC CT teams and EVS does final QA/QC on the content before loading into Protégé/NCIt. EVS generates the final, updated CDISC terminology files and posts the files on the NCI Ftp site. EVS also produces a diff file that programmatically lists all changes from last quarter’s release to the current quarter’s release; this file is also posted to the NCI Ftp. CDISC updates codetable mapping files on the CT webpage on CDISC.org. CDISC communicates the update to their user community via list-serv and website updates.

Scope

The CDISC Terminology Team supports Teams support the terminology needs of all CDISC foundational standards (SDTM, CDASH, ADaM, SEND) and all CFAST disease/therapeutic area standards. Depending on the scope and complexity of the new/modified terms to be developed, each team has about term undergoes a 3-month development cycle.   The team evaluates the requests received, incorporating as much as possible into the package for each quarterly release.  Each quarter has a public review comment period followed by a publication release.  All approved controlled terminology is stored on the NCI EVS Fftp Ftp site and can be accessed via the CDISC website.

CDISC staff coordinate the teams and maintain the membership through careful selection of volunteer experts who can contribute to its various sub-teams with their technical or therapeutic-based subject matter expertise. Volunteers can contribute by contacting the leadership team or any team lead.

Operating Model & Meetings

• There is an ongoing need to add or modify terminology for existing codelists to support CDISC user community requests as well as foundational and therapeutic area standards.
• All requests for new terms or modifications to existing terms are made through the New Term Request webpage here: https://ncitermform.nci.nih.gov/ncitermform/?version=cdisc, which can also be accessed via the CDISC Controlled Terminology website.
• Most terminology sub-teams meet weekly for 1-2 hours to address requests that come in from the New Term Request Page. Meetings are canceled if there is nothing to discuss. Meeting date/times are stored on this page: https://wiki.cdisc.org/x/UIJX. 
• All requests for new terms or modifications to existing terms are made through the New Term Request webpage here: https://ncitermform.nci.nih.gov/ncitermform/?version=cdisc, which can also be accessed via the CDISC Controlled Terminology website.
• CT Meeting quorum is defined as at least 1 team lead plus 3 additional team members, not including NCI-EVS or CDISC personnel.
• New CT teams may be created as needed based on the needs of new CDISC standards. Individual CT teams may be dissolved if they are no longer needed.

• CT teams adhere to the CT Guiding Principles: Guiding Principles
