论文摘要
急诊科（ED）拥挤仍然是一个公共卫生问题，也是患者安全问题。导致ED拥挤的基本因素众多，多样化且复杂。尽管缺乏院内床通常被视为拥挤的主要原因，但埃德（Ed）对其他辅助资源（包括成像，咨询和实验室）的依赖性也会导致拥挤。使用与成像相关的回顾性数据，包括延迟，处理时间和图像顺序的数量，从大型1层创伤中心中，我们开发了一个离散的事件模拟模型，以确定成像延迟和捆绑图像订单对ED中患者时间的影响。灵敏度分析的结果表明，与某些患者的成像和捆绑相关的延迟减少了10％的延迟，可以显着（p值<0.05）减少患者在ED中花费的时间。
Emergency Department (ED) overcrowding continues to be a public health issue as well as a patient safety issue. The underlying factors leading to ED crowding are numerous, varied, and complex. Although lack of in-hospital beds is frequently attributed as the primary reason for crowding, ED's dependencies on other ancillary resources, including imaging, consults, and labs, also contribute to crowding. Using retrospective data associated with imaging, including delays, processing time, and the number of image orders, from a large tier 1 trauma center, we developed a discrete event simulation model to identify the impact of the imaging delays and bundling image orders on patient time in the ED. Results from sensitivity analysis show that reducing the delays associated with imaging and bundling as few as 10% of imaging orders for certain patients can significantly (p-value < 0.05) reduce the time a patient spends in the ED.
