Underlying technologies

This guide is based on the HL7 FHIR standard. Implementers of this specification therefore need to understand some basic information about these specifications.

FHIR

This implementation guide uses terminology, notations and design principles that are specific to FHIR. Before reading this implementation guide, it’s important to be familiar with some of the basic principles of FHIR as well as general guidance on how to read FHIR specifications. Readers who are unfamiliar with FHIR are encouraged to read (or at least skim) the following prior to reading the rest of this implementation guide.

• FHIR overview
• Developers introduction (or Clinical introduction)
• FHIR data types
• Using codes
• References between resources

• Base resource

This implementation guide supports the R4 version of the FHIR standard. R4 is recently published and the goal is to ensure the implementation guide is aligned with the current direction of the FHIR standard. Because this IG focuses on workflow issues between an Ordering Provider and the Rendering Provider, implementers should also familiarize themselves with the FHIR resources and operations listed on the FHIR Artifacts Overview page.
