(1) The prescribing system creates the MedicationRequest with a valid externally referencable identifer and POSTs this to the shared record system. The shared record system adds the logical id on receipt. The MedicationRequest is only shared once ready for pharmacy processing so the status will only deal with valid end-states.

(2) The dispensing system directly sends an event notification to the pharmacy system with the identifer for the MedicationRequest.

(3) The dispensing system GETs the MedicationRequest from the shared record system using the identifer.

(4) The dispensing system creates the MedicationDispense with a valid externally referencable identifer and POSTs this to the shared record system. The shared record system adds the logical id on receipt. The MedicationDispense is only shared once ready to share with the pharmacy system so the status will only deal with valid end-states.

(5) The dispensing system directly sends an event notification to the prescibing system with the identifer for the MedicationDispense.
