Notice

The official version of the OHIE workflows can be found in the OpenHIE Architecture Specification.

Overview

Description: This transaction allows the Point-of-Service (PoS) systems to update a patient record in the client registry. The following sequence diagram show the steps involved.

Sponsor: Shaun Grannis (in collaboration with the Client Registry community)

Status: In Progress

Referenced Standards and APIs:

  • 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.

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.
