Sign InFHIR API — Healthcare Interoperability Programming Interface
What Is FHIR API?
A FHIR API is a RESTful programming interface based on the FHIR standard that enables modern web and mobile applications to read and write clinical data efficiently. It uses Resources (Patient, Observation, Encounter, among others) represented in JSON or XML, making it accessible to developers experienced with standard web technologies.
Unlike legacy HL7 v2, which relies on messages with proprietary syntax, FHIR APIs follow REST principles and are inherently developer-friendly. This has accelerated the creation of digital health ecosystems where multiple applications can connect to the same clinical system.
In the United States, the 21st Century Cures Act mandates that healthcare providers expose FHIR APIs for patient and third-party access. Companies like Epic, Microsoft, and InterSystems already offer FHIR APIs. In Latin America, adoption is advancing driven by national interoperability projects.
Why It Matters in Healthcare
- Open ecosystem: enables labs, pharmacies, and patient apps to integrate with the core clinical system through a standard interface.
- Agile development: developers can build health applications using conventional web tools (REST, JSON).
- Patient access: makes it easy for patients to view their clinical data from authorized mobile applications.
- Regulatory compliance: addresses mandates like the 21st Century Cures Act and Latin American interoperability regulations.
- Standard evolution: FHIR is the future of healthcare interoperability, gradually replacing HL7 v2 messaging.
