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

Overview

Description: This transaction allows a Point-of-Service (PoS) systems to store a patient's demographics in the Client Registry. The following sequence diagram shows the steps that occur during this transaction.

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

Status: In Progress

Referenced Standards and APIs:

  • ADT^A01, ADT^A04, ADT^A05 - PIF IHE ITI-8 Transactions

Assumptions and prerequisites

  • The Point-of-Service (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).
  • The workflow will result in a positive acknowledgement message when the patient is successfully created in the Client Registry or if the patient already exists in the Client Registry.  
  • The workflow will not register a duplicate patent if the patient already exists in the Client Registry.     

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.

The message may include both identifiers and demographic attributes for the patient to be registered. The format of the message is specified by the ITI-8 IHE PIX v2 transaction and takes the form of an HL7v2.3.1 A01 (Admission of an in-patient into a facility), A04 (Registration of an outpatient for a visit of the facility), or A05 (registration of patient information ahead of actual admission) message depending on whether the message is the result of admitting and in-patient into a facility, registering an outpatient, or pre-admission of an in-patient.
