Which function does the Appointment desk tab - Past serve?

The Appointment desk tab - Past serves to list past visits and cancelled appointments. This function is crucial for reviewing a patient's history with respect to their scheduled appointments. It allows users to track when patients attended their appointments, identify any cancellations, and understand overall attendance patterns. Accessing this information can help healthcare providers manage their schedules more effectively and improve patient engagement by addressing missed appointments.

The other functions do not align with what the Past tab is designed to provide. For instance, it does not show future appointments, which pertains to forward-looking scheduling, nor does it specifically display completed orders or highlight administrative notes, which are unrelated to appointment status. Thus, the correctness of the chosen function lies in its specific focus on the historical aspect of patient visits and cancellations.
