HL7 FHIR
HL7 FHIR (Fast Healthcare Interoperability Resources) is a modern healthcare data standard developed by Health Level Seven International that defines a set of resources and APIs for exchanging electronic health records. It uses RESTful APIs, JSON/XML formats, and a modular resource-based approach to enable interoperability between different healthcare systems. FHIR aims to simplify implementation while providing the flexibility to handle complex clinical and administrative data.
Developers should learn FHIR when building healthcare applications that need to exchange patient data, integrate with electronic health record systems, or comply with interoperability regulations like the US 21st Century Cures Act. It's essential for creating telehealth platforms, patient portals, clinical decision support tools, and health data analytics systems that require standardized data formats across disparate healthcare IT environments.
