Abstract

The interaction between the emergency department and the inpatient unit is important in providing quality health care to patients. The number of patients waiting for a bed in the inpatient unit affects the workflow in the department because of the congestion that can result. In this sense, a longboarding time is detrimental to both the patients and the caregivers. This paper proposes a Discrete Event Simulation (DES) model of process flowchart in an Emergency Department (ED) and three Inpatient Units (IUs) using Arena Software. The objective is to assess and investigate the impact of resources allocation in the Emergency Department and the Inpatient Units on the boarding time indicator and the wait time for beds in the Emergency Department. We found that adding beds in the Inpatient Units decreased the boarding time up to 53% and the waiting time for an ED bed decreased up to 73%.
急诊病人登机时间分析:离散事件模拟方法
急诊科和住院部之间的相互作用对于向患者提供高质量的医疗保健非常重要。在住院部等待床位的患者数量会影响该部门的工作流程,因为可能会导致拥堵。从这个意义上说,长时间的登机对患者和护理人员都是有害的。本文利用Arena软件,提出了一种急诊室(ED)和三个住院单元(IUs)流程的离散事件仿真(DES)模型。目的是评估和调查急诊科和住院部资源分配对住院时间指标和急诊科床位等待时间的影响。我们发现,在住院部增加床位可减少高达53%的登机时间,而急诊科床位的等待时间可减少高达73%。
