Experts from across health IT, including members of the HL7 board and advisory council, say the new standard can do big things for data exchange, but it’s not a cure-all. On January 2, Health Level Seven debuted the new version of its interoperability specification. Many CIOs and technologists in healthcare have been awaiting the fourth iteration of the Fast Healthcare Interoperability Resources standard FHIR 4, for short because future changes now will be backward compatible.Applications that implement the normative parts of R4 no longer risk being non-conformant to the standard, said FHIR Product Director Grahame Grieve on the FHIR blog.Grieve also said that, in addition to the base platform, several key pieces of FHIR also now are normative, including the RESTful API, the XML and JSON formats, the terminology layer, the conformance framework and its Patient and Observation resources.
