Overview

This transaction allows Point-of-Service (PoS) systems to query for patients that match supplied demographics. 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 care 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
