FHIR, or Fast Healthcare Interoperability Resources, is a standard for exchanging healthcare information electronically. Developed by HL7 International, it aims to simplify the sharing of health data between different systems, making it easier for healthcare providers to access and use patient information. The FHIR standard uses modern web technologies, such as RESTful APIs and JSON, to facilitate data exchange. This approach allows developers to create applications that can easily connect to various healthcare systems, improving interoperability and enhancing patient care by ensuring that relevant information is readily available when needed.
