The aim of this study is to investigate the characteristics and outcomes of shared bicycle-related injuries from a large emergency medical centre in China in five years from January 2017 to December 2021.
This study was conducted by reviewing the electronic medical record database of a large hospital in China for cases of shared bicycle-related injuries in five years from January 2017 to December 2021. The collected information included demographic data, injury characteristics, and outcomes. Multivariate logistic regression analysis was used to identify risk factors for fatal injury among victims.
Most shared bicycle-related injuries occurred in male (60.50%), aged 18-35 (38.81%). Company employees (29.28%) were the majority of victims of shared bicycle-related injuries. Riding in a motor vehicle lane was the most common unsafe riding behaviour (26.52%). The lower limb was the most frequently injured body region (25.28%). Bruising (28.73%) was the most commonly diagnosed injury type. The fatality rate was 9.53%, 72.24% of victims recovered well without permanent disability, and 18.23% of victims had permanent disabilities. The length of hospital stay of most of the victims (67.54%) was less than 7 days, and the hospitalization cost of most of the victims (51.93%) was less than 20,000 Yuan. Riding in a motor vehicle lane, running red lights, and cycling against traffic flow are risk factors for fatal injury.
This study indicated that shared bicycle-related injuries make up a sizeable proportion of injuries presenting to the emergency department and with diverse injury characteristics and outcomes. The findings reflect that shared bicycle-related injury has become a public health problem. Therefore, it is necessary to establish injury prevention strategies for the safety of shared bicycle users.
本研究旨在调查2017年1月至2021年12月这五年间中国一家大型急救医疗中心与共享单车相关损伤的特征及结局。
本研究通过回顾中国一家大型医院的电子病历数据库，收集2017年1月至2021年12月这五年间与共享单车相关损伤的病例。收集的信息包括人口统计学数据、损伤特征及结局。采用多因素logistic回归分析确定受害者中致命伤的危险因素。
大多数与共享单车相关的损伤发生在男性（60.50%），年龄在18 - 35岁（38.81%）。公司员工（29.28%）是与共享单车相关损伤的主要受害者群体。在机动车道骑行是最常见的不安全骑行行为（26.52%）。下肢是最常受伤的身体部位（25.28%）。擦伤（28.73%）是最常见的诊断损伤类型。死亡率为9.53%，72.24%的受害者恢复良好，无永久性残疾，18.23%的受害者有永久性残疾。大多数受害者（67.54%）的住院时间少于7天，大多数受害者（51.93%）的住院费用少于20,000元。在机动车道骑行、闯红灯和逆行是致命伤的危险因素。
本研究表明，与共享单车相关的损伤在急诊科就诊的损伤中占相当大的比例，且损伤特征和结局多样。研究结果反映出与共享单车相关的损伤已成为一个公共卫生问题。因此，有必要为共享单车使用者的安全制定损伤预防策略。
