Cancelling an appointment
Open the appointment and set its status to Cancelled. The slot is freed up on the calendar, and the appointment stays visible with its cancelled status rather than disappearing, so there's still a record it happened.
Letting the patient know
If the clinic is cancelling on the patient, send them a quick message using the cancellation template so they hear about it straight away instead of turning up to a closed slot.
If a patient cancels on themselves
If your clinic allows it, patients can request a cancellation through online booking as well — this shows up the same way as a cancellation made in the calendar.
Rebooking after a cancellation
A cancelled appointment doesn't automatically create a new one. If the patient still needs to be seen, book a new appointment for them, or add them to the waitlist if nothing suitable is available yet.
