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 Fast Healthcare Interoperability Resources (FHIR, / f aɪər /, like fire) standard is a set of rules and specifications for the secure exchange of electronic health care data. It is designed to be flexible and adaptable, so that it can be used in a wide range of settings and with different health care information systems.
The intended information transmission technology might use a messaging, document exchange, or services approach. SAIF is the framework that is required to rationalize interoperability of standards. SAIF is an architecture for achieving interoperability, but it is not a whole-solution design for enterprise architecture management.
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]
HL7 (HL7v2, C-CDA) – a standardized messaging and text communications protocol between hospital and physician record systems, and between practice management systems; Fast Healthcare Interoperability Resources (FHIR) – a modernized proposal from HL7 designed to provide open, granular access to medical information
With three weeks left in the 2024 NFL regular season, it seems likely that at least a few records will be broken. Keep an eye on these marks.
[DEC] Device Enterprise Communication - supports publication of information from point-of-care medical devices to applications such as clinical information systems and electronic health record systems, using a consistent Health Level Seven version 2 (HL7 v.2) messaging format and device semantic content or DICOM profile.
