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.
Structured Product Labeling (SPL) is a Health Level Seven International (HL7) standard which defines the content of human prescription drug labeling in an XML format. [1] The "drug labeling" includes all published material accompanying a drug, such as the Prescribing Information which contains a great deal of detailed information about the drug.
The HL7 Clinical Document Architecture (CDA) is an XML-based markup standard intended to specify the encoding, structure and semantics of clinical documents for exchange. In November 2000, HL7 published Release 1.0. The organization published Release 2.0 with its "2005 Normative Edition". [1]
The HL7 Consolidated Clinical Document Architecture (C-CDA) is an XML-based markup standard which provides a library of CDA formatted documents. Clinical documents using the C-CDA standards are exchanged billions of times annually in the United States.
FHIR builds on previous data format standards from HL7, like HL7 version 2.x and HL7 version 3.x. But it is easier to implement because it uses a modern web-based suite of API technology, including a HTTP-based RESTful protocol, and a choice of JSON, XML or RDF for data representation. [1]
In the opinion of HL7 and its members, the CDA CCD combines the benefits of ASTMs Continuity of Care Record (CCR) and the HL7 Clinical Document Architecture (CDA) specifications. It is intended as an alternate implementation to the one specified in ASTM ADJE2369 for those institutions or organizations committed to implementation of the HL7 ...
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).
Health Level Seven International (HL7) is a non-profit ANSI-accredited standards development organization that develops standards that provide for global health data interoperability. The 2.x versions of the standards are the most commonly used in the world.
