比较即时应急人员急救组协调行为的聚合和非线性测量：一项对照实验模拟研究

Abstract Background When accidents and disasters happen, emergent ad-hoc groups of immediate responders form to provide aid before the arrival of professional medical responders. Little is known about how immediate responders coordinate with each other over time and how that coordination affects the quality of the first aid that is provided. Emergency response is described as complex and chaotic, but methods for analyzing complexity have rarely been applied in the emergency response context. This exploratory study aims to compare recurrence quantification analysis and aggregated data analysis
