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.
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.
Interoperability between disparate clinical information systems requires common data standards or mapping of every transaction. However common data standards alone will not provide interoperability, and the other requirements are identified in "How Standards will Support Interoperability" from the Faculty of Clinical Informatics [2] and "Interoperability is more than technology: The role of ...
In 2020, Brazil's Ministry of Health, by the IT Department of the SUS, started one of the world's largest platforms for national health interoperability, called the National Health Data Network, which uses HL7 FHIR r4 as a standard in all its information exchanges. [34]
EHNAC grew out of the 1993 Workgroup for Electronic Data Interchange (WEDI) meeting, sponsored by the Network Architecture and Accreditation Technical Advisory Group. The healthcare transactions industry agreed there was a need for a self-governing body to develop standards for the industry, and the Association for Electronic Health Care Transactions (AFEHCT) championed the cause by sponsoring ...
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.
In the United States, there are no standards for semantic interoperability of health care data; there are only syntactic standards. This means that while data may be packaged in a standard format (using the pipe notation of HL7, or the bracket notation of XML), it lacks definition, or linkage to a common shared dictionary. The addition of ...
Continuity of Care Document - The Continuity of Care Document (CCD) represents a core data set of the most relevant administrative, demographic, and clinical information facts about a patient's healthcare, covering one or more healthcare encounters. The primary use case for the CCD is to provide a snapshot in time containing the germane ...
