As e-scooters have become common modes of transportations in urban environments, riding e-scooters has become a common mechanism of injury. This study examines the relationship between when riders are using these devices (i.e. day of week, and time of the day) and injury incidence based on data from a large U.S. city.
This study is a retrospective cohort study of patients in the trauma registry at a level one trauma center. Registry data were combined with a publicly available dataset of all e-scooter trips that occurred during the study period. Frequency of injuries and trips were analyzed using ANOVA. Poisson regressions were conducted to calculate incidence rate ratios associated with injury incidence by day of the week and time of day.
A total of 194 injured e-scooter patients were admitted to the trauma center during the study period. Patients were injured most often on Fridays (21%) and most often presented between 18:00-23:59 (38%). E-Scooter riders in general, most often rode on Saturdays (20%) and between 12:00-17:59 (44%). There was no significant relationship between day of week and injury. Riders in the early morning (IRR = 16.7, p < .001 95% CI: 10.5, 26.6), afternoon (IRR = 2.0, p = .01 95% CI: 1.2, 3.4), and evening (IRR = 3.7, p < .001 95% CI: 2.3, 6.2) had significant increased injury incidence compared to morning riders.
E-Scooter injury incidence varies by the time of day. The time of day in which a person rides an e-scooter can have a significant impact on the likelihood that the person will sustain an injury.
随着电动滑板车在城市环境中成为常见的交通工具，骑电动滑板车已成为常见的受伤机制。本研究根据美国一大型城市的数据，研究了骑手使用这些设备的时间（即一周中的哪一天和一天中的什么时候）与受伤发生率之间的关系。
本研究是对一家一级创伤中心创伤登记处的患者进行的回顾性队列研究。登记处的数据与研究期间发生的所有电动滑板车出行的公共可用数据集相结合。使用方差分析分析伤害和出行的频率。进行泊松回归以计算与工作日和时间相关的受伤发生率的发病率比。
在研究期间，共有 194 名受伤的电动滑板车患者被送往创伤中心。患者受伤最常见的是星期五（21%），最常见的就诊时间是 18:00-23:59（38%）。一般来说，电动滑板车骑手最常在星期六（20%）和 12:00-17:59（44%）骑行。星期几与受伤之间没有明显的关系。清晨（IRR=16.7，p<.001 95%CI：10.5，26.6）、下午（IRR=2.0，p=.01 95%CI：1.2，3.4）和傍晚（IRR=3.7，p<.001 95%CI：2.3，6.2）的骑手与早上的骑手相比，受伤发生率显著增加。
电动滑板车受伤发生率随时间而异。一个人骑电动滑板车的时间会对他/她受伤的可能性产生重大影响。
