Validate Patient

Validate Patient Overview

  • The local system sends a validate request to the NHI with an nhi-id and patient details
    • if a ‘dormant’ nhi-id is used, the response will include the ‘live’ nhi-id
  • In Parameters:
    • Patient resource
    • onlyCertainMatches: 1 (True)
  • The NHI validates the nhi-id and provided details against patient records held on the NHI
  • The NHI returns a bundle with an nhi-id if a validation has been successful
  • The bundle will also include a search score.

Validate Patient processing steps:

  1. The user initiates a validate request in the integrating application
  2. The integrating application sends an HTTP POST request using a $match operation to the NHI with ‘In Parameters’ (A patient resource and onlyCertainMatches set to True). E.g. Post<Endpoint>/Patient/$match
  3. The request is validated - ALT: Validation failure. OperationOutcome resource returned
  4. The NHI validates whether the Patient details and nhi-id provided are a match
  5. If there is a certain match the NHI FHIR API returns a Bundle containing only the Patient record with the nhi-id showing. Alt: Empty Bundle returned with OperationOutcome resource returned.
  6. The integrating application displays the results of the validate to the user.
