This blog introduces participants working on clinical data exchange and value-based care to HL7’s Fast Healthcare Interoperability Resources (FHIR) standard and Connectathon, an event that tests FHIR’s interoperability mettle. Since Connectathon 1 in 2012, the buzz around FHIR has grown exponentially. Word on the street is HL7 has trouble finding hotel conference rooms large enough to fit all attendees! HL7 will host Connectathon 14 in January 2017 in San Antonio.
