In-Scope

This document provides functional implementation guidance for the HL7 FHIR operations defined to query the Ontario Provincial Client Registry (PCR). This document is a 'point in time' reference which represents that most current 'dialect' of FHIR that the PCR supports. This implementation guide is based on FHIR R4.

Note that the business and technical requirements framing PCR FHIR queries are shared by the alternative HL7 V2 and HL7 V3 standards also supported for PCR query use.

Out of Scope

General PCR onboarding guidance including delivery methodology, required resources, and conformance testing requirements are currently out-of-scope for this document. Please contact the Ontario Health Registries Product Management Team at oh-ds_registries@ontariohealth.ca to initiate an integration with the PCR and receive supporting onboarding material.

PCR FHIR implementation guidance pertaining to non-functional connectivity with the Ontario Health ONE Access Gateway (OAG), is currently out-of-scope for this document. Please refer to the cross-reference links defined under the “Connectivity” sub-section accordingly.

This document does not cover prior PCR FHIR versions (other than to note updates in the version history), and does not contain a mapping between the PCR HL7 FHIR and alternative PCR HL7 V2 and HL7 V3 query specifications.
