Abstract

ABSTRACT This paper presents the results concerning the evaluation of the processes of an Emergency Department (ED). Based on the analysis of both processes and data flow, a simulation model of patient throughput in the ED has been developed. Simulation results, obtained using the JaamSim software, pointed out the strengths and weaknesses of the departments’ operations. Then, several alternative scenarios (hypothetical solutions) were created and tested, while the results were thoroughly analysed. In order to prioritise the several scenarios, two hierarchical processes were used. Firstly, a multicriteria table was developed based on decision makers’ personal preference. Total length of stay was acknowledged as the factor with the higher importance. Consequently, the application of an analytical hierarchical process (AHP) managed to verify the primary ranking. A comparison of the proposed ideas was attempted, featuring the implementation of a fast track unit as the best practice.

运用模拟与层次分析法(AHP)相结合的方法改进急诊科(ED)的操作

摘要本文介绍了对急诊科流程的评估结果。在分析流程和数据流的基础上，建立了急诊室患者吞吐量的仿真模型。使用JaamSim软件获得的模拟结果指出了各部门运营的优势和劣势。然后，创建并测试了几个备选方案（假设解决方案），同时对结果进行了彻底分析。为了优先考虑几个场景，使用了两个分层过程。首先，基于决策者的个人偏好建立了一个多准则表。总住院时间被认为是具有较高重要性的因素。因此，应用层次分析法（AHP）验证了主要排名。尝试对拟议的想法进行比较，将实施快速通道单元作为最佳做法。
