Workflow Maturity


  • 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


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).


  • 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.
