FHIR (Fast Healthcare Interoperability Resources) is an international standard being developed by the FHIR community and supported by HL7, an international standards organization. 
The standard refers to health and administrative data pertaining to patients, delivery of care, and health organizations, throughout the patient journey and across the continuum of care. 
FHIR is more than a data model; it is part of a paradigm shift in health care. 
It is a revolution championing patient-centric, proactive, personalized, data-driven care.
