The goal of this study was to understand the impact of COVID-19 pandemic and associated lockdown measures on the volume, rate, and type of trauma presenting to the emergency department (ED) by using trauma-initiated CT studies to capture patient data.
We performed a retrospective observational study comparing patients undergoing CT scans for trauma during the 1 and 2 lockdown periods compared to corresponding prepandemic months. During two lockdown periods, public places such as restaurants, libraries, parks, and shops across the province were shut down. Government-led messaging advised that people should stay at home and practice social distancing. The rate of trauma-initiated CT scans and the proportion of different types of traumas were compared between time periods.
There was no significant difference in overall trauma-initiated CT scans between the prepandemic and pandemic levels. Motor vehicle collision (MVC) cases decreased from 18.2% to 15.6% during the first lockdown period ( = 0.049) and also reduced from 29.1% to 25.2% during the second lockdown period ( = 0.013). Trauma from falls increased from 19.1% to 27.5% ( = 0.036) during the first lockdown, despite no significant change during the 2 lockdown. Furthermore, the percentage of stab injuries increased from 25.0% to 38.9% while blunt trauma decreased from 68.5% to 54.3% during two lockdowns ( = 0.015).
The total number of trauma-initiated CT scans did not significantly decrease during the lockdown periods. Stabbings and falls increased during lockdown periods while MVCs and blunt trauma decreased.
本研究的目的是通过利用创伤引发的CT研究来收集患者数据，以了解新冠疫情大流行及相关封锁措施对急诊科（ED）创伤就诊量、发生率和类型的影响。
我们进行了一项回顾性观察研究，将1次和2次封锁期间因创伤接受CT扫描的患者与疫情前相应月份的患者进行比较。在两次封锁期间，全省范围内的餐厅、图书馆、公园和商店等公共场所均被关闭。政府发布的信息建议人们应居家并保持社交距离。比较不同时间段创伤引发的CT扫描率以及不同类型创伤的比例。
疫情前和疫情期间创伤引发的CT扫描总量无显著差异。在第一次封锁期间，机动车碰撞（MVC）病例从18.2%降至15.6%（P = 0.049），在第二次封锁期间也从29.1%降至25.2%（P = 0.013）。跌倒所致创伤在第一次封锁期间从19.1%增至27.5%（P = 0.036），尽管在第二次封锁期间无显著变化。此外，在两次封锁期间，刺伤的比例从25.0%增至38.9%，而钝器伤从68.5%降至54.3%（P = 0.015）。
封锁期间创伤引发的CT扫描总数没有显著下降。封锁期间刺伤和跌倒所致创伤增加，而机动车碰撞和钝器伤减少。
