Emergency departments (EDs) generally receive many casualties in disaster or mass casualty incidents (MCI). Some studies have conceptually suggested the surge capacity that ED should have; however, only few studies have investigated measurable numbers in one community. This study investigated the surge capacity of the specific number of accommodatable patients and overall preparedness at EDs in a metropolitan city.

大城市急诊部门的应急能力和大规模伤亡事故准备：一项区域调查研究。

急诊科 (ED) 通常会在灾难或大规模伤亡事件 (MCI) 中造成大量人员伤亡。一些研究从概念上提出了 ED 应该具有的激增能力；然而，只有少数研究调查了一个社区的可测量数字。本研究调查了大城市中特定数量的可容纳患者的激增能力和急诊室的整体准备情况。
