Orthopaedic injuries after electronic scooter trauma in a level 1 trauma centre before and after introduction of an escooter ride-sharing scheme

The Victorian state government introduced a trial electronic scooter sharing scheme on 1st February 2022 in inner city Melbourne. Despite epidemiological data from other jurisdictions that show these devices are associated with significant trauma. This is a descriptive study from the largest trauma centre in Victoria demonstrating the “scope of the problem” after introduction of this government-approved, ride sharing scheme.Retrospective case series. Our hospital orthopaedic department database was searched from 1/1/2021 to 30/6/22 to identify all presentations associated with electronic scooter trauma, the mechanism of injury and admission information was confirmed via chart review. Data collected included: mode of arrival, alcohol/drug involvement, hospital LOS, injury severity score, ICU admission, list of injuries, operations undertaken, surgical procedures, discharge destination, death.In the 12 months prior to and 5 months since introduction of the ride share scheme, 43 patients were identified. 18 patients (42% of our cohort) presented in the 5 months since ride sharing was introduced, and 25 patients in the preceding 12 months.58% were found to be alcohol or drug affected. All patients were admitted to hospital, 14% of which included ICU admission. 44% were polytrauma admissions. Median hospital length of stay was 2 days. The longest individual hospital stay was 69 days. No patients in this series died. There were 49 surgical procedures in 35 patients including neurosurgical, plastics and maxillofacial operations. Mean Injury Severity Score was 10.Despite data demonstrating their danger in other jurisdictions, the Victorian state government approved a trial of an electronic scooter ride share scheme in inner Melbourne in February 2022. These devices are associated with a significant trauma burden and the rate has increased since the introduction of the ride-sharing scheme. This data may be combined with other hospital data and could be used to inform policy makers.
