Police reports indicate an increasing burden of electric bike (E-bike) casualties in China; however, hospitalised injury data have not been reported. The aim of the present work was to describe hospitalised injury patterns for E-bikers involved in road crashes and explore injury risk disparities among them. For the period October 2010 to April 2011, this cross-sectional study retrospectively collected information for hospitalised E-bikers involved in road crashes from hospital records, in Suzhou China, using the International Classification of Diseases, 10th revision (ICD-10) injury diagnosis codes. Injury nature and body region were further categorised using ICD-10 codes. Multivariate logistic regression was used to assess the risk of specific injury types. We found that hospitalised E-biker injuries (n=323) accounted for 57.2% of road traffic hospitalisations over the 6-month study period. The average age, length of stay and hospitalisation cost were 43.8 years, 10.0 days and ¥8229 (US$1286), respectively. Fractures and head injuries were common. The odds of traumatic brain injuries were significantly elevated for night-time E-bike crashes and incidents other than colliding with motor vehicles. These findings confirm E-bike injuries as an important population health problem and identify elevated injury odds in different E-biker groups. Future injury prevention initiatives should include encouraging helmet use among E-bikers.
警方报告显示，中国电动自行车伤亡负担日益加重；然而，住院受伤数据尚未见报道。本研究的目的是描述道路交通事故中电动自行车骑行者的住院损伤模式，并探讨他们之间的损伤风险差异。在2010年10月至2011年4月期间，这项横断面研究在中国苏州，利用国际疾病分类第10版（ICD - 10）损伤诊断编码，从医院记录中回顾性收集道路交通事故中住院电动自行车骑行者的信息。损伤性质和身体部位进一步使用ICD - 10编码进行分类。采用多因素logistic回归评估特定损伤类型的风险。我们发现，在为期6个月的研究期间，住院电动自行车骑行者损伤（n = 323）占道路交通住院病例的57.2%。平均年龄、住院时间和住院费用分别为43.8岁、10.0天和8229元人民币（1286美元）。骨折和头部损伤很常见。夜间电动自行车事故以及与机动车碰撞以外的事故导致创伤性脑损伤的几率显著升高。这些发现证实电动自行车损伤是一个重要的人群健康问题，并确定了不同电动自行车骑行者群体中较高的损伤几率。未来的伤害预防措施应包括鼓励电动自行车骑行者佩戴头盔。
