Appointment State Diagram

Introduction

It is important to understand the state transitions during the scheduling process and the typical flow of statuses for an Appointment and associated Slot resources. This State Diagram should be referenced to when considering the statuses of the scheduling resources.

Typical booking including the Slot resource from context of the scheduling service. (modified from the Appointment resource notes)

Step	Activity Description (Role: Scheduler)	Slot	Appointment
1	The schedule is created/published	status = free
2	An appointment availability request is processed to locate available slots for all participants	status = free
3	An appointment availability request is processed and available appointments created		status = proposed, participant.status = needs-action
4	Optional: The hold request for an available appointment is processed and the slot status updated for all participants	status = busy
5	Optional: An appointment hold request is processed and the appointment updated.		status = pending, participant.status = tentative
6	The appointment request is processed and the slot status updated for all participants	status = busy
7	Optional: The patient is registered within the system. I.e., create Patient resource for patient and appointment is accepted by patient		patient participant.status = accepted
8	The appointment is confirmed as accepted by all participants	status = busy	status = booked, participant.status = accepted

Rejection of an appointment request by scheduler beginning from steps 4 or 6.

Step	Activity Description (Role: Scheduler)	Slot	Appointment
4r or 6r	The appointment request is processed and unable to update slot status for all participants. (i.e., slot status != free)	status varies
6r	The appointment is cancelled. Update participant status	status varies	status = cancelled, participant.status = declined (may be other statuses too)

Cancellation of an appointment by client following step 8.

Step	Activity Description (Role: Scheduler)	Slot	Appointment
8	The appointment is confirmed as accepted by all participants	status = busy	status = booked, participant.status = accepted
9c	An appointment cancel request is processed. The client cancels the appointment when it is declined by patient		patient participant.status = declined
10c	The appointment is cancelled	status = free	status = cancelled, participant.status = declined

Release of a hold on an appointment by client following step 5.

Step	Activity Description (Role: Scheduler)	Slot	Appointment
5	An appointment hold request is processed and the appointment updated.		status = pending, participant.status = tentative
6c	An appointment hold release request is processed. The hold is removed by client before it expires.	status = busy	patient participant.status = tentative
11c	The appointment hold is released	status = free	status = cancelled, participant.status = tentative
