Presentation the Simulation Model for Paraclinical Services in Shiraz Hafez Hospital ‎and ‎Evaluate Scenarios to Reduce Waiting Time

The queue is one of the most complex social systems in which human lives are inevitably ýassociated with the activities of organizations. Due to the characteristics of healthcare ýorganizations and the critical role that planning plays in such organizations, research in this regard ýcan be of great help. This paper was an attempt to demonstrate the role and use of the branches ýof the operations research discipline in healthcare centers.
The current research was a cross-sectional study conducted onþ þý2614ýþ þpatients referred to the ýparaclinic ward of Hafez Hospital, Shiraz, Iran. In order to collect data, the patient code, time of arrival, work start time, serving start and end time were recorded with the help of staff and two assistants at the time of arrival of the patients. Then, modeling and optimization of patient flow were conducted using queues and simulation techniques. The data was analyzed using SPSS software and Input Analyzer ýSoftware and the system was simulated using Arena software.
The results showed that 30% of the patients no longer wished to be referred back to the center. ýThe findings also revealed that there was a significant difference between the standard waiting ýtime and the time spent in the hospital to recive a service. Among the 6 different scenarios, the ýmixed scenario reduced waiting time of the first service forþ þsonography patients to 75.04 minutes ýand for radiology patients to 65.573 minutes.
The results showed that the suggested model, in comparison to the current model of health ýcenters, can improve theþ þquality of services and reduce the duration of time patients must wait ýuntil receiving the first serviceþ.
