E-scooter incidents in Berlin: an evaluation of risk factors and injury patterns

Background E-scooters have emerged as a frequently used vehicle in German cities due to their high availability and easy access. However, investigations about the causes and mechanisms of E-scooter incidents and their trauma-specific consequences are rare. Methods We analysed all patients involved in E-scooter incidents from June to December 2019 who presented to four inner-city EDs in Berlin. The prospective data included patient-related and incident-related data, information on injury patterns and therapy, responses in a voluntary questionnaire concerning E-scooter use and general traffic experience. Results 248 patients (129 males; median age 29 years (5-81)) were included: 41% were tourists and 4% were children. Most incidents (71%) occurred between July and September 2019, the majority occurring at weekends (58%). The injury pattern was mostly multifocal, affecting the lower (42%) and upper limbs (37%) and the head (40%). Traumatic brain injury was associated with alcohol consumption. Inpatient admission was recorded in 25%, surgery in 23%. Conclusion This study has defined the incidence of injury related to E-scooter use in a major European city. Stricter laws governing the use of E-scooters, the wearing of helmets and technical modifications to the E-scooter platforms might decrease E-scooter-associated incidents and resulting injuries in the future.

Automated summary

E-scooters have become a frequently used mode of transportation in German cities, with a study in Berlin showing that most incidents involved male tourists, resulting in multifocal injuries often associated with alcohol consumption. Stricter regulations on E-scooter use, the requirement for helmets, and technical modifications to E-scooter platforms could potentially reduce the number of incidents and injuries in the future.
