However, despite the importance of this system, a few studies have been done on its evaluation and existing researches in this field have investigated topics, such as designing a web-based appointment system (19), patient satisfaction of online appointment booking systems (4,20), development of information technology acceptance model for an online appointment booking system in hospitals (21)(22)(23), implementation and use of the online appointment booking system in clinics (15,20), and improving the management of appointments (24,25). There are limited studies in Iran on the need for smart systems to prepare an optimized program for patients and investigating the appointment-making system of private physicians' offices (5,22).…”
