【摘要】 在大型医院的急救一体化模式中,急诊室与下游住院科室床位配置不合理,往往引起急诊部拥堵不堪,病人等待时间较长等问题。特别考虑病人在急诊室滞留的同时接受下一阶段服务,且服务不可抵消的急诊过程,建立考虑滞留的急诊部两阶段床位配置仿真模型,在科室优先权不同的情景下,从滞留可能性的角度研究床位配置对急诊效率的影响,确定相对较优的床位配置方案,四种权重系数方案下滞留可能性依次降至6.00%、4.27%、5.45%、5.11%。最后对病人的到达率进行灵敏度分析。更多还原

【Abstract】 In the context of emergency integrated mode in big hospitals,unreasonable beds allocation between upstream EDs and downstream related inpatient departments leads to ED congestion and longer blocking times.The model of patient flow was proposed,wherein if the downstream departments are full,patients would accept second-stage service at the same time if their first-stage services are blocked.An empirically based two-stage bed allocation simulation was proposed to optimize beds allocation under four different department priorities,and blocking probability decreased to 6.00%,4.27%,5.45%,5.11% under optimal beds allocation.Multiple sensitivity analysis tested the variation of the results to changes in patient arrival rate.更多还原
