Fast Healthcare Interoperability Resources (FHIR) is a standard for exchanging healthcare information electronically. Developed by Health Level Seven International (HL7), FHIR aims to simplify the sharing of health data between different systems, making it easier for healthcare providers to access and use patient information. FHIR uses modern web technologies, such as RESTful APIs and JSON, to facilitate data exchange. This approach allows developers to create applications that can quickly and efficiently interact with healthcare data, improving patient care and streamlining administrative processes across various healthcare settings.
