Background:<\/b> Waiting times for health services arise because capacity does not match demand or capacity or\u00a0demand is not well managed. Queuing theory is a powerful operational research tool which assists managers to\u00a0<\/span>make vital decisions capable of optimizing the performance of a health system facility, minimize operational costs\u00a0<\/span>and enhance the satisfaction of all interest groups.<\/span><\/p>

Objective:<\/b> To simulate the queuing model in the outpatient pharmacy in order to evaluate its performance and to\u00a0<\/span>develop necessary strategies for optimizing dispensing service.<\/span><\/p>

Methods:<\/b> The study was carried out at the Pharmacy Unit of Family Medicine \/ General Outpatient Department\u00a0(GOPD) of Lagos University Teaching Hospital employing workflow analysis and time study. A sample size of 123\u00a0<\/span>Ambulatory Patients was studied and data were collected daily over a period of four weeks. Data analysis was done\u00a0<\/span>using SPSS version 10.0 to determine waiting time for prescription validation and assessment, payment, filling,\u00a0<\/span>collection and counselling. The queuing system in Pharmacy was then simulated to determine measures such as\u00a0<\/span>Service Utilization Factor, Average Queuing Time in the queue and in the system, Average number of patients in\u00a0<\/span>queue and in the system, Waiting cost and Service cost all of which are necessary for evaluating service delivery in\u00a0<\/span>the outpatient setting.<\/span><\/p>

Results:<\/b> The study revealed a total patient waiting time of 79.24 min with the process component accounting for\u00a07.9 \u00b1 5.58 min (9.97%) and delay component responsible for 71.34 \u00b1 66.93 min (90.03%). It was established that\u00a0<\/span>optimal service delivery would be achieved with two service points requiring six pharmacists in the pharmacy unit.\u00a0<\/span>This arrangement is expected to give an 88.1% reduction in mean total patient waiting time and 50% deduction in\u00a0<\/span>total cost when compared with existing system.<\/span><\/p>

Conclusion:<\/b> Significant reduction in waiting time can be made by facilitating service delivery at the prescription\u00a0validation and assessment point. The excessive waiting time contributed by delay components underscored the\u00a0<\/span>need to employ more pharmacists to improve on the service system. Service efficiency would be optimized by\u00a0<\/span>increasing the number of service points to two in order to minimize the total operating costs.<\/span><\/p>
