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. [1] Since December 2016, CDISC standards are mandatory for submission to US FDA. [2] [3]
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 [7] (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. [8] ODM was first introduced in 1999, and the latest version, 1.3.2, was released in 2012. [9] 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. [10]
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 [11] 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.
CDISC BRIDG model is a unifying model of the domain of clinical research and research studies. It defines basic elements such as investigator, subject, study, intervention. It is used to keep all standards consistent. It was first introduced in 2006 with version 2 released in 2008. It can be obtained as UML model as well as OWL format.
CDISC SHARE (Shared Health and Clinical Research Electronic Library) is a metadata repository that supports the development, governance, publishing, and consumption of CDISC standards in human and machine-readable formats. SHARE helps users find, understand, and use rich metadata (i.e., research concepts, data elements and attributes, the relationship among data elements, properties in a relationship, and controlled terminologies) relevant to clinical studies more efficiently and consistently. With all this information in a single repository, SHARE will improve integration and traceability of clinical data end-to-end, from protocol through analysis. SHARE will provide a collaborative standards development environment that will improve quality, integration, and consistency across CDISC standards.
CDISC maintains a list of solutions providers, subject matter experts and consultants deemed to have sufficient knowledge and experience implementing the various CDISC standards.
Electronic data capture (EDC) systems can be certified as compliant with the Operational Data Model (ODM) by CDISC. There are two main types of integration, ODM Import and ODM Export.
Full import allows importing of ODM-formatted clinical data (Metadata and Data). This is useful for setting up the EDC system to capture data. It basically allows third party software to define the forms, variables etc. used in the EDC system. This provides an EDC vendor-neutral system for defining a study.
The EDC system will generate ODM data files for further processing. For example, REDCap Cloud data capture systems to allow export of a study in ODM. [12]
Health Level Seven, abbreviated to HL7, is a range of global standards for the transfer of clinical and administrative health data between applications with the aim to improve patient outcomes and health system performance. The HL7 standards focus on the application layer, which is "layer 7" in the Open Systems Interconnection model. The standards are produced by Health Level Seven International, an international standards organization, and are adopted by other standards issuing bodies such as American National Standards Institute and International Organization for Standardization. There are a range of primary standards that are commonly used across the industry, as well as secondary standards which are less frequently adopted.
The common warehouse metamodel (CWM) defines a specification for modeling metadata for relational, non-relational, multi-dimensional, and most other objects found in a data warehousing environment. The specification is released and owned by the Object Management Group, which also claims a trademark in the use of "CWM".
A metadata registry is a central location in an organization where metadata definitions are stored and maintained in a controlled method.
JT is an openly-published ISO-standardized 3D CAD data exchange format used for product visualization, collaboration, digital mockups, and other purposes. It was developed by Siemens.
An electronic data capture (EDC) system is a computerized system designed for the collection of clinical data in electronic format for use mainly in human clinical trials. EDC replaces the traditional paper-based data collection methodology to streamline data collection and expedite the time to market for drugs and medical devices. EDC solutions are widely adopted by pharmaceutical companies and contract research organizations (CRO).
Catalogue Service for the Web (CSW), sometimes seen as Catalogue Service - Web, is a standard for exposing a catalogue of geospatial records in XML on the Internet. The catalogue is made up of records that describe geospatial data, geospatial services, and related resources.
A Clinical Research Coordinator (CRC) is a person responsible for conducting clinical trials using good clinical practice (GCP) under the auspices of a Principal Investigator (PI).
PREservation Metadata: Implementation Strategies (PREMIS) is the de facto digital preservation metadata standard.
SDTM defines a standard structure for human clinical trial (study) data tabulations and for nonclinical study data tabulations that are to be submitted as part of a product application to a regulatory authority such as the United States Food and Drug Administration (FDA). The Submission Data Standards team of Clinical Data Interchange Standards Consortium (CDISC) defines SDTM.
The Standard for Exchange of Nonclinical Data (SEND) is an implementation of the CDISC Standard Data Tabulation Model (SDTM) for nonclinical studies, which specifies a way to present nonclinical data in a consistent format. These types of studies are related to animal testing conducted during drug development. Raw data of toxicology animal studies started after December 18, 2016 to support submission of new drugs to the US Food and Drug Administration will be submitted to the agency using SEND.
The following outline is provided as an overview of and topical guide to clinical research:
Energistics is a global, non-profit, industry consortium that facilitates an inclusive user community for the development, adoption and maintenance of collaborative, open standards for the energy industry in general and specifically for oil and gas exploration and production.
Regulated Product Submission (RPS) is a Health Level Seven (HL7) standard designed to facilitate the processing and review of regulated product information. RPS is being developed in response to performance goals that the U.S. Food and Drug Administration (FDA) is to achieve by 2012, as outlined in the Prescription Drug User Fee Act (PDUFA). In addition to the U.S., regulatory agencies from Europe, Canada, and Japan are at varying levels of interest and participation. Currently, the second release of RPS is in development.
Additive manufacturing file format (AMF) is an open standard for describing objects for additive manufacturing processes such as 3D printing. The official ISO/ASTM 52915:2016 standard is an XML-based format designed to allow any computer-aided design software to describe the shape and composition of any 3D object to be fabricated on any 3D printer via a computer-aided manufacturing software. Unlike its predecessor STL format, AMF has native support for color, materials, lattices, and constellations.
In order to comply with government regulatory requirements pertinent to clinical trials, every organization involved in clinical trials must maintain and store certain documents, images and content related to the clinical trial. Depending on the regulatory jurisdiction, this information may be stored in the trial master file or TMF, which today takes the form of an electronic trial master file (eTMF). The International Conference on Harmonization (ICH) published a consolidated guidance for industry on Good Clinical Practice in 1996 with the objective of providing a unified standard for the European Union, Japan, and the United States of America to facilitate mutual acceptance of clinical data by the regulatory authorities in those jurisdictions. This guidance document established the requirement across all ICH regions to establish trial master files containing essential documents that individually and collectively permit evaluation of the conduct of a trial and the quality of the data produced.[2] In some jurisdictions, for example the USA, there is no specific requirement for a trial master file. However, if the regulatory authority requires ICH GCP to be followed, then there is consequently a requirement to create and maintain a trial master file.[2]
In computing, a data definition specification (DDS) is a guideline to ensure comprehensive and consistent data definition. It represents the attributes required to quantify data definition. A comprehensive data definition specification encompasses enterprise data, the hierarchy of data management, prescribed guidance enforcement and criteria to determine compliance.
An electronic trial master file (eTMF) is a trial master file in electronic format. It is a type of content management system for the pharmaceutical industry, providing a formalized means of organizing and storing documents, images, and other digital content for pharmaceutical clinical trials that may be required for compliance with government regulatory agencies. The term eTMF encompasses strategies, methods and tools used throughout the lifecycle of the clinical trial regulated content. An eTMF system consists of software and hardware that facilitates the management of regulated clinical trial content. Regulatory agencies have outlined the required components of eTMF systems that use electronic means to store the content of a clinical trial, requiring that they include: Digital content archiving, security and access control, change controls, audit trails, and system validation.
3D Manufacturing Format or 3MF is an open source file format standard developed and published by the 3MF Consortium.
The portal for medical data models is a German and European medical research infrastructure. It is an open-access metadata-repository initiated for scientific purposes that can generate, analyse, release and reuse medical forms.
A common data model (CDM) can refer to any standardised data model which allows for data and information exchange between different applications and data sources. Common data models aim to standardise logical infrastructure so that related applications can "operate on and share the same data", and can be seen as a way to "organize data from many sources that are in different formats into a standard structure".
