What is FHIR? An API-First Standard for Healthcare Data Exchange
What is FHIR - FirestarterPro FirestarterPro FHIR (Fast Healthcare Interoperability
HL7 established FHIR (Fast Healthcare Interoperability Resources) as its API-first standard for healthcare data exchange.
Summary
FHIR, developed by HL7, is an API-first standard that treats healthcare data as JSON resources. This approach solves the problems of complex legacy formats (v2 and v3), providing a mechanism easily accessible to developers.

Details
FHIR (Fast Healthcare Interoperability Resources) is an API-first standard for exchanging healthcare data developed by HL7. Historically, healthcare systems relied on flat, positionally dependent messages (HL7 v2) or overly complex XML schemas (HL7 v3). FHIR addresses these challenges by modeling healthcare concepts as modular 'Resources,' which are accessible via standard RESTful HTTP using JSON serialization. In this model, distinct concepts like Patient, Observation, and Condition are treated as independent resources. Standard CRUD operations (GET, POST, PUT, DELETE) map directly to standard HTTP verbs. Relationships between these resources are managed through the 'Reference' type, maintaining data integrity. For practical implementation, FHIR utilizes 'Profiles' and 'Extensions.' Profiles tighten the base specification for specific contexts (e.g., US Core), defining required elements or restricting code choices. Extensions allow developers to add custom data elements not covered by the core spec. This combination ensures both flexibility and adherence to real-world clinical needs, enabling rapid system integration development.
