Analysing injury types, injury severity and mortality in victims of accidents with electric bicycles in comparison with conventional bicycles.
Prospective cohort study.
Data of patients treated at the Accident & Emergency Department of the University Medical Center Groningen after a bicycle accident are being entered in a database since 2014. We have analysed this database for accidents with electric bicycles (e-bikes) and conventional bicycles occurring among adult patients for the period of July 2014 to May 2016. 'Propensity score matching' was used to match e-bikers to conventional cyclists, based on age, gender and the presence of comorbidities.
107 of the 475 included victims were riding an e-bike. Average age of e-bikers and conventional cyclists was 65 years and 39 years respectively. Comorbidity was more common in e-bikers. E-bikers were injured significantly more severely than conventional cyclists. They had more severe injuries of the head and face, and upper and lower extremities. E-bikers were also admitted to the hospital more often, and for longer periods, and they underwent surgery more often. Mortality was the same. Propensity score matching revealed that e-bikers had multiple severe injuries (ISS > 15) twice as often as conventional cyclists, that they had more severe head injuries and were admitted for longer periods than conventional cyclists.
E-bikers who had a bicycle accident had more severe injuries, more frequently had multiple injuries and had more severe head injuries than conventional cyclists. This resulted in a greater need for care. Preventive measures such as riding lessons and helmet use should be encouraged. Care providers should pay extra attention to the possibility of severe injuries when a patient had a bicycle accident with an e-bike.
比较电动自行车事故受害者与传统自行车事故受害者的损伤类型、损伤严重程度和死亡率。
前瞻性队列研究。
自2014年以来，格罗宁根大学医学中心急诊科治疗的自行车事故患者数据被录入数据库。我们分析了该数据库中2014年7月至2016年5月期间成年患者发生的电动自行车（电动助力车）和传统自行车事故。采用“倾向得分匹配”方法，根据年龄、性别和合并症情况，将电动助力车骑行者与传统自行车骑行者进行匹配。
475名纳入的受害者中，107人骑的是电动助力车。电动助力车骑行者和传统自行车骑行者的平均年龄分别为65岁和39岁。合并症在电动助力车骑行者中更为常见。电动助力车骑行者的受伤程度明显比传统自行车骑行者更严重。他们的头面部、上肢和下肢有更严重的损伤。电动助力车骑行者住院的频率也更高，住院时间更长，接受手术的频率也更高。死亡率相同。倾向得分匹配显示，电动助力车骑行者发生多处重伤（损伤严重度评分>15）的频率是传统自行车骑行者的两倍，他们头部受伤更严重，住院时间比传统自行车骑行者更长。
与传统自行车骑行者相比，发生自行车事故的电动助力车骑行者受伤更严重，更频繁地出现多处损伤，头部受伤也更严重。这导致对护理的需求更大。应鼓励采取如骑行课程和佩戴头盔等预防措施。当患者发生电动自行车事故时，护理人员应格外关注严重受伤的可能性。
