NHS Booking and Referral Standard

Reschedule

The Reschedule operation supports amending the slot a booking is made against. The slot is the only element capable of being changed as part of the reschedule operation, if either the .status or .reasonCode require amendment, the Update operation can be followed, otherwise, the Rebook operation.

Steps to Reschedule:

Perform a GET operation using the .id of the appointment to /Appointment/{id}. Alternatively, if the .id is not known, a search of the Registry can be undertaken following the Document Reference Standard Pattern - Sender. NB: If a match cannot be obtained using this method the process of updating must be performed manually
Request Available slots from the service
Select a new slot
Update the resource with the new slot. NB: Only the .slot element of the resource must be updated
Perform a PATCH operation using the id of the appointment to /Appointment/{id}
Once processed, the Receiver of the booking must update (PUT) the pointer in the central Registry, as described in Document Reference Standard Pattern - Receiver. The principal update to the pointer is to change the .context element to alter the slot time -

"context": {
  "period": {
    "start": "2025-02-12T12:30:30+00:00",
    "end": "2025-02-12T12:40:30+00:00"
  }
}

In this example the Appointment resource is with the existing slot, and updated with the newly selected slot.
