Clinical Data Interchange Standards Consortium
The Clinical Data Interchange Standards Consortium (CDISC) is a standards developing organization (SDO) dealing with medical research data linked with healthcare,made to enable information system interoperability and to improve medical research and related areas of healthcare. The standards support medical research from protocol through analysis and reporting of results and have been shown to decrease resources needed by 60% overall and 70–90% in the start-up stages when they are implemented at the beginning of the research process. Since December 2016, CDISC standards are mandatory for submission to US FDA.
CDISC standards are harmonized through a model that is also a HL7 standard and is the process to becoming an ISO/CEN standard.
The CDISC Operational Data Model (ODM) is designed to facilitate the regulatory-compliant acquisition, archive and interchange of metadata and data for clinical research studies. ODM is a vendor-neutral, platform-independent format for interchange and archive of clinical study data. The model includes the clinical data along with its associated metadata, administrative data, reference data and audit information. ODM was first introduced in 1999, and the latest version, 1.3.2, was released in 2012. ODM extensions have been developed to create a number of additional CDISC standards, including Define-XML, Dataset-XML, SDM-XML, and CTR-XML and future planned standard Protocol-XML.
ODM is an XML based standard and it is an XML schema that provides a number of constructs for modelling electronic Case Report Forms (CRFs). ODM is often combined with the Study Data Model standard to more fully model trial arms or trial activities. ODM is also used in sending forms data from a clinical trial system to an electronic health record (EHR) system.
The ODM schema is generally divided into three categories of data: Metadata, Admin data, and Clinical data. Metadata describes the structure of the eCRFs within the study, and how they relate to scheduled visits. Admin data contains references to users, locations, and any additional non-structural and non-clinical reference data. Clinical data contains all eCRF item values and references both Metadata and Admin data.
Define-XML supports the interchange of dataset metadata for clinical research applications in a machine-readable format. An important use case for Define-XML is to support the submission of clinical trials data in CDISC SDTM, SEND or ADaM format to regulatory authorities. The key metadata components to support submissions are:
Define-XML can also be used to describe proprietary, non-CDISC dataset structures. The Define-XML model is implemented using extensions to the CDISC Operational Data Model (ODM) XML schema. The current version is 2.0 published on the CDISC website.
Clinical Trial Representation allows representing basic characteristics of a clinical trial, such as study sponsor, study name, size of the trial (number of participants). The standard was first introduced in 2016.
