基于病人成本最小化的医院预约挂号研究

为了减少病人排队挂号的等待时间及优化医院自身资源的合理配置,近几年我国各大医院都先后开展预约挂号服务.然而,医院在开展预约挂号时面临的问题是:预约挂号为病人带来了多少好处和便捷,预约数量和病人总挂号成本存在什么样的关系,到底开放多少预约号最为合适?本文从病人的角度对上述问题进行了定量研究.论文将病人的挂号成本分为时间成本和费用成本两类,运用了排队论建立了预约量与病人总挂号成本的模型,得出了预约挂号的个体选择依据和系统选择依据,并从总挂号成本与预约量的关系中得到使所有病人总挂号成本最小的最优预约量.然后,进一步分析了最优预约量中各个参数的敏感性,以期为医院的预约挂号管理工作提供指导.

Hospital Appointment and Registration Management Based on Minimization Patients Cost

In order to decrease patient's waiting time and optimize the collocation of hospital's resource, many large hospitals have recently developed the appointment and registration system. However, there are some issues when hospitals are developing the system--how much benefit and convenience the system brings to patients,what relationship is between the appointment amount and the total registration cost, and how many appointment is optimal. All these problems are considered in this paper by quantitative analysis from patients' point. The patients' total registration cost is divided into time cost and fee cost. Using the results of the queuing theory, we build the model about the appointment amount and the total registration cost,and gain the individual selection principle and system selection principle of the appointment and registration , respectively. And we have a conclusion that there exists an optimal appointment amount which minimizes the total registration cost.Then,when all parameters are given,we can compute out the optimal appointment amount. Finally,the sensitivity of all parameters is analyzed, in order to provide suggestions about the appointment and registration management.
