Abstract

Currently, Suan Prung Hospital is a hospital serving psychiatric patients in health zones 1 and 2 encompassing 13 provinces within the northern region of Thailand. This extensive coverage has led to congestion issues in the hospital and difficulties faced by patients residing in remote areas who encounter challenges in accessing healthcare services. Additionally, the increased patient load in the hospital has placed a heavier burden on the hospital staff. In light of these circumstances, Suan Prung Hospital has implemented the “Drug-dispensing Service at Community Pharmacies” project, aimed at alleviating congestion, enhancing healthcare accessibility, and reducing the workload of the hospital staff. In an effort to identify methods for cost reduction and workload optimization among pharmacists at the hospital, this study proposes an approach to enhance the logistical workflow. The investigation comprises two sections. Firstly, an analysis of the hospital's pharmaceutical inventory management has been conducted to mitigate costs, determine the economic order quantity (EOQ) and reorder point, and explore the optimal reserve amount (safety stock). The second section involves employing the Arena 14 program to simulate specific scenarios. Three model situations have been examined: the process of out-patient department (OPD) patients receiving their regular medications at the hospital, the process of medication dispensation to pharmacies involved in the project, and the patient service process at the project-affiliated pharmacies. The aim of these simulations is to identify strategies that not only reduce costs but also enhance the efficiency of the aforementioned processes, thereby informing future improvements.
