Mass Casualty Incidents (MCIs) involving high-speed passenger ferries (HSPFs) may result in the dual-wave phenomenon, in which the emergency department (ED) is overwhelmed by an initial wave of minor injuries, followed by a second wave of more seriously injured victims. This study aimed to characterize the time pattern of ED presentation of victims in such accidents in Hong Kong.
All HSPF MCIs from 2005 to 2015 were reviewed retrospectively, with the time interval from accident to ED registration determined for each victim. Multivariable linear regression was used to identify independent factors associated with the time of ED presentation after the accidents.
Eight MCIs involving 492 victims were identified. Victims with an Injury Severity Score (ISS) ≥ 9 had a significantly shorter median time interval compared to those with minor injuries. An ISS ≥ 9 and evacuation by emergency service vessels were associated with a shorter delay in ED arrival, whereas ship sinking, accident at nighttime, and a longer linear distance between the accident and receiving ED were associated with a longer delay.
The dual-wave phenomenon was not present in HSPF MCIs. Early communication is the key to ensure early resource mobilisation and a well-timed response.
涉及高速客船（HSPF）的大规模伤亡事件（MCIs）可能导致双重波现象，即急诊科（ED）最初被轻度受伤的患者淹没，随后是第二波更严重受伤的受害者。本研究旨在描述香港此类事故中 ED 呈现受害者的时间模式。
回顾性审查了 2005 年至 2015 年的所有 HSPF MCI，并确定了每位受害者从事故到 ED 登记的时间间隔。多变量线性回归用于确定与事故后 ED 呈现时间相关的独立因素。
确定了 8 起涉及 492 名受害者的 MCI。损伤严重程度评分（ISS）≥9 的受害者与轻伤受害者相比，中位数时间间隔明显缩短。ISS≥9 和使用紧急服务船只疏散与 ED 到达延迟缩短有关，而沉船、夜间事故以及事故和接收 ED 之间的直线距离较长与延迟较长有关。
HSPF MCI 中不存在双重波现象。早期沟通是确保早期资源动员和及时响应的关键。
