Left click on an appointment, then click the DNA button.
Selecting this option on the menu will mark the appointment as the patient having missed the appointment. It will change the appointment to the colour defined in the calendar configuration settings (grey by default). If you make a mistake, just select DNA a second time and it will return the original state.
The system will check whether the patient has another appointment booked in the future. If they do not, you will be prompted by the system as to whether you want to schedule a follow-up task. This defaults to contact them in 2 days, but can be edited under Settings->System Configuration.
If you do want a task, click “OK”, otherwise click “Cancel” and no follow-up will be scheduled. The follow-ups are designed to help you avoid losing touch with DNAs and thereby improve your patient retention.
Follow up tasks are automatically set to autodelete when if the patient books an appointment in the future.
