This page is part of the PACIO Personal Functioning and Engagement Implementation Guide (v1.0.0: STU 1) based on FHIR (HL7® FHIR® Standard) R4. This is the current published version. For a full list of available versions, see the Directory of published versions

Underlying Technologies

Based on the HL7 FHIR standard, this implementation guide uses terminology, notations, and design principles that are specific to FHIR. Implementers of this specification therefore need to understand some basic information about this specification.

Fast Healthcare Interoperability Resources

Before reading this implementation guide, familiarity with some of the basic principles of FHIR as well as general guidance on how to read FHIR specifications is required. Readers who are unfamiliar with FHIR are encouraged to read the following prior to reading the rest of this implementation guide.

• FHIR overview
• Developer’s introduction
• FHIR data types
• Using codes
• References between resources
• How to read resource & profile definitions
• Base resource
• Security
• Security Labels

This implementation guide supports the R4 version of the FHIR standard and builds on the US Core STU5.0.1 Implementation Guide; implementers need to familiarize themselves with the profiles in that guide.
