Major Trauma among E-Scooter and Bicycle Users: a Nationwide Cohort Study

ObjectivesTo determine the incidence, demographics and injury patterns involved in E-Scooter-related hospital admissions due to significant trauma compared with bicycle-related trauma within England and Wales. To compare morbidity and mortality between groups.DesignA retrospective cohort study based on data which has been prospectively collected and submitted to the UK Trauma Audit and Research Network (TARN) registry.SettingMajor trauma centres and trauma units within England and Wales.ParticipantsPatients of any age who were admitted to hospitals in England and Wales with injuries following E-Scooter or bicycle incidents between the dates 1 January 2021–31 December 2021. All patients must have met TARN database inclusion criteria.OutcomesIn-hospital mortality, critical care admission and length of stay (LoS), hospital LoS and discharge destination.ResultsThere were 293 E-Scooter trauma incidents compared with 2538 bicycle incidents. E-Scooter users were more likely to be admitted to a major trauma centre (p=0.019) or a critical care unit (p<0.001). Serious head and limb trauma (Abbreviated Injury Scale >2) occurred more frequently among the E-Scooter cohort (35.2% vs 19.7%, p<0.001 and 39.9% vs 27.2%, p<0.001, respectively) while serious chest and pelvic trauma were greater among bicycle users (p<0.001 and p=0.003, respectively). Over one-third of E-Scooter injuries were incurred outside the current legislation by patients who were intoxicated by alcohol and drugs (26%, 75/293) or under the age of 17 (14%, 41/293).ConclusionsThese early results suggest a greater relative incidence of serious trauma and an alternative pattern of injury among E-Scooter users compared with bicycles.Trial registration numberTARN210101.
