# Create Patient Demographic Record Workflow
## Overview
This transaction allows a Point-of-Service (PoS) system to store a patient's demographics in the Client Registry. The following sequence diagram below shows the steps that occur during this transaction.
| **Workflow Maturity** | 
Mature
| - 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
|

| Standard(s) \* | | 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.

| 1 | Register Patient (Demographics) | 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. | PIF ITI-8 transactions ADT^A01, ADT^A04, ADT^A05

| 3 | Acknowledge patient is in the CR | The response message is an HL7 ACK. See ITI TF-2x: C.2.3, "Acknowledgment Modes" for definition and discussion of the ACK message. | PIF ITI-8 transactions HL7 ACK
