What is FHIR?
FHIR (Fast Healthcare Interoperability Resources) is a standard developed by HL7 International for exchanging healthcare information electronically. It defines a set of "resources" that represent clinical and administrative data concepts, making it possible for different health IT systems to communicate seamlessly.
Why FHIR R4 Matters
Release 4 (R4) is the first "normative" version of FHIR, meaning its core specifications are stable and will not change in backward-incompatible ways. This makes R4 the version trusted by enterprises and regulators for production systems.
- RESTful API architecture for easy integration with modern web technologies
- JSON and XML support for flexible data representation
- Modular resource model that can be adopted incrementally
- Strong community adoption with thousands of implementations worldwide
- Mandated by the U.S. CMS Interoperability Rule for patient data access
How Kaldor Uses FHIR
Every system we build is FHIR-native from the ground up. Our platforms expose FHIR R4 APIs for clinical data exchange, enabling interoperability with EHR systems, laboratory information systems, insurance platforms, and identity registries without proprietary middleware.
