FHIR

HL7's Fast Healthcare Interoperability Resources (FHIR) is a RESTful API standard using 'Resources' (like Patient or Observation) to enable rapid, secure exchange of clinical and administrative data.

FHIR (Fast Healthcare Interoperability Resources) is the modern, open standard from Health Level Seven (HL7) for exchanging healthcare data. It leverages modern web technologies (RESTful APIs) and defines modular data components called 'Resources' (e.g., Patient, Medication) to simplify system integration. This approach significantly lowers development barriers, allowing for rapid creation of interoperable applications; major vendors (e.g., Epic, Microsoft) now support it. FHIR is crucial for creating a connected health ecosystem, facilitating secure, real-time data access for clinicians and patients, and is often mandated in regulations like the US 21st Century Cures Act.
