Understanding SMART on FHIR
The global open standard for health data interoperability
What is FHIR?
FHIR (Fast Healthcare Interoperability Resources) is a healthcare data exchange standard developed by HL7 International. Using modern web technologies (RESTful APIs, JSON, OAuth2), it enables different healthcare systems to exchange data in a standardised way.
What Does SMART Add?
SMART (Substitutable Medical Applications, Reusable Technologies) adds an application layer framework on top of FHIR. It defines how apps securely connect to EHR systems, handle authentication and authorization — making healthcare apps plug-and-play, like apps on a smartphone.
Why Does This Matter?
Most healthcare systems worldwide are closed and incompatible. SMART on FHIR breaks down data silos, enabling patient data to flow securely between hospitals and systems — laying the foundation for precision medicine, telemedicine, and AI-assisted diagnosis.

In Practice: FHIR + GB/T Dual-Standard Architecture
Bridging international and Chinese national standards for seamless cross-border data exchange
Our initiative has pioneered a dual-standard data architecture that ensures full compatibility between the international FHIR standard and China's GB/T national standard. This innovation enables medical data to flow seamlessly across borders — when a patient moves between countries, their health records remain accessible and interoperable, regardless of which standard the local system uses.
Cross-Border Interoperability
Patient records flow seamlessly between FHIR-based international systems and GB/T-based Chinese systems.
Compliance by Design
Meets regulatory requirements in both international and Chinese healthcare environments simultaneously.
Seamless Referrals
Enables smooth patient referrals across countries without data format barriers.
