การลดต้นทุนระบบการดำเนินงานการนึ่งฆ่าเชื้อด้วยแก๊สของหน่วยงานเวชภัณฑ์กลาง กรณีศึกษาโรงพยาบาลสงขลานครินทร์

Abstract

The purpose of this project is to reduce the waiting time of medical equipment in the process of sterile in order to analyze the cost of service charges, by having the time of medical equipment that waiting on queue and the cost which are the main variable for this cast. However, this project staring by using ProModel® 2016 program to create the simulation of the sterile process, which refer to the real situation, and setting 4 indicators which are the ratio of utilization, the average waiting time, the amount of medical equipment that finished and opportunity cost. In addition, there are 2 costs that relevant and need to consider which are direct cost and indirect cost that calculated from 7 variables, in order to improve the cost of 5 difference size (GA01 GA02 GA03 GA04 and GA05) of medical equipment. In conclusion, the result has shown the service rate of using Ethylene Oxide (EtO) and Hydrogen Per Oxide (H2O2) was changed from the initial data which shown 144.04 percent and 287.67 in respectively. Regarding to the alternative 1 which using Ethylene Oxide (EtO) for sterile by adjusting the ratio of medical equipment to be 30 percent and 70 percent for apply Hydrogen Per Oxide (H2O2), this is an optimal solution that might improve the working process of the organization. Thus, this alternative can decrease the waiting time of medical equipment about 1.36 percent and can reduce the cost of waiting time which is 14.57 percent. This made the performance of the department have more efficiency in term of sending the medical equipment on time.
