The increasing use of electric personal mobility devices (ePMDs) has been accompanied by an increasing incidence of associated accidents. This study aimed to investigate the characteristics of ePMD-related injuries and their associated factors.
This cross-sectional study was conducted using data from the Emergency Department-based Injury In-depth Surveillance database from 2014 to 2018. All patients who were injured while operating an ePMD were eligible. The primary outcome was the rate of severe injury, defined as an excess mortality ratio-adjusted Injury Severity Score of ≥25. We calculated the adjusted odds ratios (AORs) of outcomes associated with ePMD-related injuries.
Of 1,391,980 injured patients, 684 (0.05%) were eligible for inclusion in this study. Their median age was 28 years old, and most injuries were sustained by men (68.0%). The rate of ePMD-related injuries increased from 3.1 injuries per 100,000 population in 2014 to 100.3 per 100,000 population in 2018. A majority of the injuries occurred on the street (32.7%). The most commonly injured area was the head and face (49.6%), and the most common diagnosis was superficial injuries or contusions (32.9%). Being aged 55 years or older (AOR, 3.88; 95% confidence interval, 1.33-11.36) and operating an ePMD while intoxicated (AOR, 2.78; 95% confidence interval, 1.52-5.08) were associated with severe injuries.
The number of emergency room visits due to ePMD-related injuries is increasing. Old age and drunk driving are both associated with serious injuries. Active traffic enforcement and safety regulations regarding ePMDs should be implemented to prevent severe injuries caused by ePMD-related accidents.
电动个人移动设备（ePMD）使用的增加伴随着相关事故发生率的上升。本研究旨在调查与ePMD相关损伤的特征及其相关因素。
本横断面研究使用了2014年至2018年基于急诊科的损伤深度监测数据库中的数据。所有在操作ePMD时受伤的患者均符合条件。主要结局是重伤率，定义为经超额死亡率调整的损伤严重度评分≥25。我们计算了与ePMD相关损伤相关结局的调整优势比（AOR）。
在1391980名受伤患者中，684名（0.05%）符合纳入本研究的条件。他们的中位年龄为28岁，大多数损伤发生在男性身上（68.0%）。与ePMD相关的损伤率从2014年的每10万人3.例增加到2018年的每10万人100.3例。大多数损伤发生在街道上（32.7%）。最常受伤的部位是头部和面部（49.6%），最常见的诊断是浅表损伤或挫伤（32.9%）。年龄在55岁及以上（AOR，3.88；95%置信区间，1.33 - 11.36）以及在醉酒状态下操作ePMD（AOR，2.78；95%置信区间，1.52 - 5.08）与重伤相关。
因ePMD相关损伤而到急诊室就诊的人数正在增加。老年和酒后驾驶均与严重损伤相关。应实施积极的交通执法和关于ePMD的安全法规，以预防ePMD相关事故导致的严重损伤。
