E-scooter rider injuries have been growing, but little is known about how trip and incident characteristics contribute to their severity.
We enrolled 105 adults injured while riding e-scooters who presented to an emergency department in Washington, DC, during 2019. Enrolled participants completed an interview during the emergency department visit, and their charts were abstracted to document their injuries and treatment. Logistic regression examined the association of incident location and circumstances with the likelihood of sustaining an injury on the Abbreviated Injury Scale (AIS) ≥ 2, while controlling for rider characteristics.
The most common locations of e-scooter injuries in our study sample occurred on the sidewalk (58%) or road (23%). Accounting for other trip and rider attributes, e-scooter riders injured on the road were about twice as likely as those injured elsewhere to sustain AIS ≥ 2 injuries (RR, 1.96; 95% CI, 1.23-2.36) and those who rode at least weekly more often sustained AIS ≥ 2 injuries compared with less frequent riders (RR, 1.86; 95% CI, 1.11-2.32).
Greater injury severity for riders injured on the road may reflect higher travel speeds. Practical applications: Injury severity associated with riding in the road is one factor that jurisdictions can consider when setting policy on where e-scooters should be encouraged to ride, but the risk of any crash or fall associated with facilities should also be examined. Although injuries are of lower severity on sidewalks, sharing sidewalks with slower moving pedestrians could potentially lead to more conflicts.
电动滑板车事故造成的伤害一直在增加，但人们对事故特征如何导致伤害严重程度的了解甚少。
我们招募了 2019 年在华盛顿特区一家急诊室就诊的 105 名在骑电动滑板车时受伤的成年人。登记的参与者在急诊室就诊期间完成了一次访谈，他们的病历被摘录以记录他们的受伤情况和治疗情况。逻辑回归分析了事故地点和情况与在简略损伤量表（AIS）上至少有一处 ≥ 2 损伤的可能性之间的关联，同时控制了骑手特征。
在我们的研究样本中，电动滑板车事故最常见的地点是人行道（58%）或道路（23%）。在考虑到其他行程和骑手属性后，在道路上受伤的电动滑板车骑手比在其他地方受伤的骑手更有可能遭受 AIS ≥ 2 损伤（RR，1.96；95%CI，1.23-2.36），而至少每周骑行一次的骑手比不经常骑行的骑手更有可能遭受 AIS ≥ 2 损伤（RR，1.86；95%CI，1.11-2.32）。
在道路上受伤的骑手的损伤严重程度更高，可能反映了更高的行驶速度。实际应用：与在道路上骑行相关的损伤严重程度是司法管辖区在制定鼓励电动滑板车骑行地点政策时可以考虑的一个因素，但也应该检查与设施相关的任何碰撞或摔倒的风险。尽管在人行道上受伤的严重程度较低，但与移动速度较慢的行人共享人行道可能会导致更多的冲突。
