The standard was created by the Health Level Seven International (HL7) health-care standards organization. FHIR builds on previous data format standards from HL7, like HL7 version 2.x and HL7 version 3.x.
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.
HL7 was founded in 1987 to produce a standard for the exchange of data with hospital information systems.Donald W. Simborg, the CEO of Simborg Systems took the initiative to create the HL7 organization with the aim to allow for wider use of its own exchange protocol (known as the StatLAN protocol, originally defined at the University of California, San Francisco in the late 1970s).
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.
The use of the HL7 FHIR standard in the Smart Guidelines has also been a point of debate, as some argue that the scarcity of trained professionals in LMICs could initially limit its adoption. However, proponents note that the widespread adoption of global standards like FHIR can ultimately benefit all countries by encouraging shared investments ...
The HL7 standards development organisation is based in America and oversees the development of the HL7 standard. HL7 current work programme includes: HL7 Version 2 (including HL7 V2.1, HL7 V2.2, HL7 V2.3, HL7 V2.3.1, HL7 V2.4 and HL7 V2.5) HL7 Version 3 (including HL7 Reference Information Model) electronic health record
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]
However, IEEE 11073 SDC does not compete with established and emerging standards like HL7 v2 or HL7 FHIR. [4] IEEE 11073 SDC is part of the established ISO/IEEE 11073 family of standards. IEEE 11073 SDC is based on the paradigm of a service-oriented architecture (SOA). The IEEE 11073 SDC family of standards currently comprises three parts: Core ...
