By providing reminders, the hospital triage queuing device can help patients who may forget their appointments and make it easier for patients who wish to cancel or reschedule patients. This reduces the number of missed appointments; it gives us the opportunity to provide an appointment to another patient, which helps us reduce waiting time and save money.

　　The first point of contact for hospital patients is usually by phone-messages, appointments or emergencies. If the experience is negative, some patients may decide not to go to the hospital at all. This may mean that the loss of revenue leads to loss of motivation for consultants and employees, or even a safety hazard. Therefore, it is essential to enter the hospital easily and efficiently through effective telephone exchange. Staff members work exclusively in communication and participate in external and internal calls. External calls are calls that come to the hospital from outside the hospital, and can come from patients, patient attendants, medical service providers, or others. The internal call is to dial the telephone exchange from the hospital to connect to another extension, employee mobile phone or other external telephone. In addition to answering calls, the telephone exchange also makes calls to reschedule appointments or invite people to participate in activities.
