Enrolment Nomination

Enrolment Nomination Overview

An ‘Enrolment Nomination ’ interaction is initiated by a user who wishes to request that a health provider enrol a patient for a health service. The request includes details of the patient, the Patient’s guardian and in some cases the provider. At a later time, after the health provider has processed the request, they send a response back to the nominated endpoint indicating if the enrolment request has been accepted or declined.

Enrolment Nomination Request

Enrolment Nomination Request processing steps:

1. Whaihua creates a bundle containing Patient, RelatedPerson and MessageHeader resources and posts it to the NES $process-message endpoint.
2. NES validates and enriches the message with additional Patient details and posts it to the HealthLink AIR Broker's $process-message endpoint. (EventType=FLS_ENROLMENT_NOMINATION)
3. The Messaging Hub transforms the message to an HL7v2.0 ADT^28 request and sends it to the PMS
4. The Messaging Hub returns a synchronous 202 response to NES

Enrolment Nomination Response processing steps:

1. The PMS sends an HL7v2.0 ADT^28 ACK message to the HealthLink AIR Broker indicating if the enrolment nomination request has been accepted or not
2. The Messaging Hub creates a bundle containing an OperationOutcome with an appropriate HL7 Result Code and sends it to the NES $process-message endpoint. The MessageHeader.response.identifier should hold the value of the Messageheader.id of the message being acknowledged
3. NES returns a synchronous 202 response to the Messaging Hub.
