To track this in the medical record, you can create an appointment type called cancelled or no show:
- Menu > Settings > Calendar > Appointments.
- Click Add Appointment Type.
You would update that scheduled visit to that type which will allow it to remain in the medical record.
You can then run appointment reports by appointment type to see all those that are set with that specific type.
Visits also have the option to update a confirm status to cancelled. If the visit is marked as cancelled you can also search by confirm status using the appointment report.
Cancelling a visit via confirm status or updating the appointment type, would not remove it from the schedule or from the patient's MR.
