跨科室资源共享模式下择期病人手术室调度研究

Operating room scheduling for elective patients under cross-department resource sharing

针对各科室病人数量和手术室相关资源不匹配导致的手术室堵塞或空闲的问题,本文从术后资源共享的角度,研究了择期病人手术室调度计划.该问题是由两个子问题组成,一个是科室之间如何建立资源共享匹配机制,另一个是如何为择期病人安排手术室.为了解决上述问题,首先,结合秩和比评价方法对科室的工作强度进行评价,之后在不同工作强度的科室之间搭建跨科室资源共享匹配机制模型,用以确定科室的合作组合和资源的流动方向,从而为后续手术室调度模型构建提供依据;其次,在科室资源服务能力变动的基础上,进一步考虑多资源(科室资源和公共资源)服务能力约束,构建了资源共享模式下手术室调度模型以最大化利用闲置资源和满足病人的手术需求;最后,利用某省三级甲等医院实际数据进行数值实验,并通过与单一科室资源服务能力约束的手术室调度相比,从不同层面验证了本文提出的跨科室资源共享模式对手术室调度的有效性.

In view of the problem of operating room congestion or idleness caused by the mismatch between the number of patients in each department and the relevant resources in the operating room,we studied the scheduling plan for elective patients in the operating room from the perspective of postoperative resource sharing.The problem consists of two sub-problems,one is how to establish a matching mechanism between departments,and the other is how to arrange operating rooms for elective patients.The specific work is divided into the following parts:First,we apply the rank sum ratio method to evaluate the work intensity of the department,and build a matching mechanism model among the departments with different work intensity to determine the cooperation combination of departments and the flow direction of resources;second,on the basis of department cooperation and changes in department resource service capacities,we further consider the service capacity constraints of multiple resources(department resources and hospital public resources),and construct the model of operating room planning under the resource sharing to maximize the usage of available resources and meet the patient’s surgical needs;third,we use the actual data from an upper first-class hospital in a certain province to conduct numerical experiments.We compare the numerical results with the operating room planning under resource service capability constraints of a single department,and the effectiveness of operating room planning proposed in this paper is verified from different perspectives.
