Changes to API Endpoint Responses for

CDISC Biomedical Concepts (BCs) and SDTM Dataset Specializations

API endpoint responses for CDISC Biomedical Concepts

(package 6) are now available in the CDISC Library.  These were developed to support the Digital Data Flow (DDF) pilot study and to continue the expansion of BCs and SDTM Dataset Specializations

have changed due to the evolution of the Biomedical Concepts data model. As a result, all API endpoints will be versioned. The original, pre-existing API endpoints will remain available in API  v1.

New API endpoints have been developed and are available in API v2. On July 6, 2023, all new and revised API endpoints for CDISC Biomedical Concepts and SDTM Dataset Specializations will be included in API v2.

Starting July 6, 2023, all API requests will need to include a version. For example,

Old API endpoint:

/mdr/bc/packages/2022-10-26/biomedicalconcepts/C64547

New API endpoints

/cosmos/v1/mdr/bc/packages/2022-10-26/biomedicalconcepts/C64547
 /cosmos/v2/mdr/bc/packages/2022-10-26/biomedicalconcepts/C64547

A version must be specified. If a user does not specify a version, a 404 API response code (Not Found) will be returned. All documentation for the CDISC Library API can be found at https://api.developer.library.cdisc.org/. Users should use their existing cdiscID login credentials.

in the CDISC Library:

  • New BCs include laboratory tests, inclusion/exclusion criteria, medical history, medical procedures, product administration, subject characteristics, subject disposition events and substance use
  • New SDTM Dataset Specializations cover multiple domains including DS, EC, EX, IE, LB, MH, PR, SC, and SU

In addition, a number of enhancements were made to existing content. CDISC Library now contains a total of 248 BCs and 227 SDTM Dataset Specializations retrievable via the CDISC Library API. Refer to Basic Construct section for endpoints marked new.

New Excel exports of the latest versions BCs and SDTM Dataset Specialization from CDISC Library are now available at COSMoS Documentation.

Introduction

CDISC biomedical concepts and dataset specializations are currently supported standards. These include an abstract conceptual layer, aligned with NCI terminology, which is linked to a simplified implementation layer of pre-configured SDTM dataset specializations.Information for additional specializations, such as CDASH data collections, will be added when they become available. 

The biomedical concepts and dataset specializations are informative content. They will start to fill gaps such as semantics, variable relationships and value level metadata. Key objectives are to reduce variability in standards implementations, increase metadata-driven automation and reduce barriers to operational implementation. 

CDISC biomedical concepts and dataset specializations will be released in incremental packages. The first package was released on October 26, 2022.  Subsequent packages have been released and are now available via CDISC Library APIs (see News and Updates).

Please use CDISC Jira for comments and feedback.
