The current Fast Healthcare Interoperability Resources (FHIR®) specification is available on http://hl7.org/fhir. A directory of past versions and draft/working versions is also available on http://hl7.org/fhir/directory.html, this includes draft standards and the current 'live' build.
FHIR® Standard for Trial Use 3 is now published.
Healthcare records are increasingly becoming digitized. As patients move around the healthcare ecosystem, their electronic health records must be available, discoverable, and understandable. Further, to support automated clinical decision support and other machine-based processing, the data must also be structured and standardised. (See Coming digital challenges in healthcare)
HL7 has been addressing these challenges by producing healthcare data exchange and information modeling standards for over 20 years. FHIR is a new specification based on emerging industry approaches, but informed by years of lessons around requirements, successes and challenges gained through defining and implementing HL7 v2 , HL7 v3 and the RIM, and CDA . FHIR® can be used as a stand-alone data exchange standard, but can and will also be used in partnership with existing widely used standards. (See Comparing FHIR to other HL7 standards)
FHIR® solutions are built from a set of modular components called "Resources". These resources can easily be assembled into working systems that solve real world clinical and administrative problems at a fraction of the price of existing alternatives. FHIR® is suitable for use in a wide variety of contexts – mobile phone apps, cloud communications, EHR-based data sharing, server communication in large institutional healthcare providers, and much more.
