This page is part of the Person-Centered Outcomes (PCO) Implementation Guide (v1.0.0-ballot: STU 1 Ballot 1) based on FHIR (HL7® FHIR® Standard) R4. No current official version has been published yet. 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.

This implementation guide supports the R4 version of the FHIR standard and builds on the US Core 6.1.0 Implementation Guide; implementers need to familiarize themselves with the profiles in that guide.
