Immunisation Event Create

Overview

The "create" operation is used to create a new immunisation event. This method performs validation checks to ensure that the event is valid before it is created.

The create operation performs the following:

  1. Check that the authorization token contains the required permission, if not it returns an error message indicating that the user does not have the required scope to create an immunisation record
  2. Check the event data with the Rejection Rules and Data Quality Rules
  3. With the Patient Identifer for the incoming event compare to all existing events for that Patient, if an exact match is found do not create a new event and return the existing, including the meta.tag exact-duplicate-not-created Exact duplicate short circuit.
  4. Create the first version of the event with the details provided
  5. Saves the new version of the event to the database.
  6. Returns the event and any validation errors in an operationOutcome.

Behaviour

Exact duplicate short circuit

With the Patient Identifer for the incomeing event compare to all existing events for that Patient, if an exact match is found do not create a new event and return the existing, and mark with the meta.tag exact-duplicate-not-created.

  • http resonse code 200
  • metag.tag exact-duplicate-not-created
  • immunization resource of the original duplicate event includeing resource.id
exact-duplicate-not-created meta.tag example
...
"meta" : {
    ...
    "tag" : [
        {
            "system" : "https://standards.digital.health.nz/ns/air-processing-terms",
            "code" : "exact-duplicate-not-created",
            "display" : "Exact duplicate not created"
        }
    ]
}
...

Create new event

  • immunisation record is validated (validation rules that can lead to rejection of the submitted Immunisation Event are listed here, and rules that result in data quality warnings are listed here)
  • If all the attributes / items in the immunisation record are valid, a new immunisation record is added to the repository, attached to the provided NHI, with the details populated from the request.

Response

Returns the created Immunization record. If there were any issues with the create, the response will contain an OperationOutcome resource array. The OperationOutcome resource has an informational issue indicating that the create operation failed. The issue array of the OperationOutcome resource would contain additional issues with appropriate severity and code values.

Scope/s required

Any FHIR scope that includes system/immunization.c , for example system/immunization.cruds and/or system/immunization.c

Notes

  • The API will validate that there are no more than two identifiers received in the request payload for patient references
  • Return a reference to the Facility in the response if there is an identifier for a facility (i.e the system is "https://standards.digital.health.nz/ns/hpi-facility-id") For example if the identifier we have for Facility is as following
    {
        "system": "https://standards.digital.health.nz/ns/hpi-facility-id",
        "value": "FZZ958-K"
    }
    

Then the "reference" should be "https://api.hip.digital.health.nz/fhir/hpi/v1/Location/FZZ958-K"

A full example for a location payload is below

"location": { 
  "reference": "https://api.hip.digital.health.nz/fhir/hpi/v1/Location/FZZ958-K",
  "identifier": {
      "system": "https://standards.digital.health.nz/ns/hpi-facility-id",
      "value": "FZZ958-K"
  }     
},
  • The operation may return data quality violations based on the data quality rules

  • The record can also be identified by ImmSOT as duplicate, see the details of this here
