CDISC Standards for Clinical Data

CDISC ODM Wiki
A series of articles about how to implement
the CDISC ODM Standard


CDISC (Clinical Data Interchange Standards Consortium) is establishing new standards for exchange, storage, archival and submission of clinical data. These standards have recently been acknowledged by the FDA. There most important of these standards are: the ODM (Operational Data Model), the Lab standard and the SDTM (Submission Data Model) and ADaM (Analysis Data Model), with others (like the Protocol Standard) coming up.
  • The ODM standard describes a format in which clinical data are stored, exchanged or archived
  • The Lab standard is used for exchange of laboratory data between labs and CROs
  • The CRT-DDS (better known as define.xml) is a standard for providing data descriptions for Case Report Tabulations in an XML format for submission to the FDA. The promise of this standard is that submissions done using the CRT-DDS can be processed considerable faster by the regulatory authorities.
  • THE CDASH standard harmonizes the content of (e)CRFs so that a 1:1 mapping with SDTM is almost possible
  • The SDTM is a standard for describing the format in which clinical data should be submitted in electronic form to the FDA
  • The ADaM is a standard for describing the format in which analysis clinical data should be submitted to the FDA
  • The Protocol standard is a standard for describing the full protocol of a clinical trial. Important parts of the Protocol standard are currently being implemented as a machine-readable format (based on ODM).

An overview of the CDISC standards can be found on the CDISC website
