What is HL7 FHIR?

FHIR (Fast Healthcare Interoperability Resources) is the modern standard for exchanging healthcare data electronically. Developed by HL7 International, it's now mandated by the 21st Century Cures Act for healthcare interoperability in the US.

Unlike older standards (HL7 v2, CDA), FHIR uses RESTful APIs and JSON - the same technologies that power modern web applications. This makes it dramatically easier to integrate healthcare data into analytics pipelines.

RESTful API - standard HTTP methods
JSON format - easy to parse and transform
OAuth 2.0 / SMART on FHIR authentication
Standardized resources across all EHR vendors
Example FHIR Patient Resource
{
  "resourceType": "Patient",
  "id": "example-patient",
  "name": [{
    "family": "Smith",
    "given": ["John", "Michael"]
  }],
  "birthDate": "1970-01-25",
  "gender": "male",
  "address": [{
    "city": "Boston",
    "state": "MA"
  }]
}
