Introduction to FHIR

XES Module for FHIR bases on the FHIR (Fast Health Interoperability Resources) R4 version v4.0.0 that is an interoperability standard designed for a faster and a more efficient electronic healthcare-related information exchange.

The core principle of this technology is the ability to exchange not entire documents, but specific pieces of information, such as patient diagnosis or date of birth. FHIR simplifies the process of retrieving only the required type of data, so that a physician does not have to look through multiple documents to find a specific piece of information about his patient. This is made possible because of the concept of "resources" in FHIR. A resource can directly refer to an appointment, immunization recommendation, or medication order - a specific piece of information.

Another important characteristic of the FHIR technology is interoperability. It helps handle the "variability" that is a result of data diversity in healthcare processes. Diversity causes a big challenge for healthcare standards today. FHIR defines a framework for adapting and extending existing resources in all systems to read these extensions without much effort. FHIR simplifies the mechanism of data exchange among healthcare applications by leveraging the models existing in the electronic healthcare ecosystem.
