FHIR, or Fast Healthcare Interoperability Resources, is a standard for electronically exchanging healthcare information. Developed by Health Level Seven International (HL7), FHIR aims to enhance interoperability in the healthcare sector. It achieves this through modularity, allowing flexible combinations of resources for different healthcare needs. FHIR utilizes RESTful APIs for easier implementation and integration and employs standardized resources like Patient and Medication. The goal is to provide a modern, web-based approach to exchanging health data, promoting seamless connectivity and data exchange across diverse healthcare systems and applications.
