Query Patient Demographic Records by Identifier Workflow

Overview

This transaction allows patient demographics to be fetched from the Client Registry using an identifier. The following sequence diagram shows the steps involved.

Workflow Maturity	Mature	One or more OpenHIE implementations of this workflow exist in one or more countries Workflow is defined and ARB approved Workflow is supported by mature standards
Standards*		Option 1 QBP^Q22 - IHE ITI-21 RSP^K22 - IHE ITI-21 Option 2 FHIR - Patient Demographics Query IHE ITI PDQm Transaction
Assumptions and Prerequisites		The PoS system is a trusted application known by the HIE and it is registered with the interoperability layer to be able to send and receive data securely (Common message security workflow).
Actors		PoS - The point of service system that captures patient identifiers, is responsible for sending the identifiers to the HIE. IL - Mediates the transactions between the PoS system and the client registry. CR - Manages patient demographics and identifier details.

Interaction Description

The following is a description of the interaction steps.

#	Interaction	Data	Transaction Options
1	Get patient by identifier	The message includes the query criteria, which may include one or more patient identifiers.	PDQ ITI-21 transaction QBP-Q22 OR Patient Demographics Query IHE ITI PDQm Transaction
2	Get patient from CR by identifier	The message from the PoS is passed directly through to the CR by the IL	PDQ ITI-21 transaction QBP-Q22 OR Patient Demographics Query IHE ITI PDQm Transaction
3	Return patient record	The response returns the patient(s) that matched the query criteria. It may consist of zero or more patient demographic records.	PDQ ITI-21 transaction RSP-K22 OR Query Patient Resource Response (ITI TF-2c:3.Y1.4.2): Bundle (Patient)
4	Return patient record	The message from the CR is passed directly through to the PoS by the IL	PDQ ITI-21 transaction RSP-K22 OR Query Patient Resource Response (ITI TF-2c:3.Y1.4.2): Bundle (Patient)
