基于精益生产与系统仿真的门诊输液系统改善

Improvement of the transfusion system in the hospital thanks to lean production and simulation

为了提高医院服务效率与质量，探索把精益生产和系统仿真方法应用于某医院门诊输液系统的改善工作中。在描述与分析某医院门诊输液系统总体管理现状与存在的问题基础上，重点给出了患者等候时间长的因果图，采用“5W1H”和“ECRS＂方法分析了输液流程，应用Simio软件对现有输液系统进行了仿真模拟，根据仿真数据绘制了输液系统价值流现状图。应用价值流图分析方法，并根据少人化和一个流的思想，从重新配置护士与调整传送带速度两方面，提出了输液系统改善方案，并采用仿真模拟方法验证了改善效果。结果表明，采用精益生产和系统仿真可有效改善门诊输液系统，提升医疗效率与医疗服务水平。

In order to improve the efficiency and quality of medical services, the authors applied the lean production and system simulation into optimizing the transfusion system of a hospital. By means of describing and analyzing the current situation and problems of a transfusion system of the hospital, the paper presented the cause-effect diagram for overlong patient waiting. ＂5W1H＂ and ＂ECRS＂ were adopted to analyze the infusion processes, while Simio was used to simulate the existing infusion system and simulation data so obtained were used to draw a value stream mapping for the system. In line with the ideas of Shojinka and one stream production, nurses deployment and conveyor speed were reconfigured. Based on these ideas, a reform plan is presented and the simulation method is used to verify the outcomes. The study proved that lean production and system simulation can effectively improve the hospital transfusion system, medical efficiency and medical service level.
