This transaction allows the Point-of-Service (PoS) systems to update a patient record in the client registry. The following sequence diagram shows the steps involved.
Workflow Maturity
  • Workflow is defined and ARB approved
  • Workflow is supported by mature standards
  • One or more OpenHIE implementations of this workflow exist in one or more countries
ADT^A08 - IHE ITI-8 Transactions
Assumptions and Prerequisites
  • The Point-of-Service 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).
  • The Patient to be updated is assumed to already exist in the Client Registry.
  • 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.
