Rideshare electric scooter accidents have led to increasing emergency department (ED) visits and neurosurgical consultations. This study categorizes e-scooter-related injuries requiring neurosurgical consultation at a single level 1 trauma center. Patients who required neurosurgical consultation from June 2019 to June 2021 with a positive finding on computed tomography imaging were selected for review of patient and injury characteristics, resulting in a sample size of 50 cases. Average patient age was 36.9 (15-69) years, and 70% were male. Seventy-four percent of patients were under the influence of alcohol and 12% illicit drugs. None (0%) were helmeted. Seventy-eight percent of accidents occurred between 6:00 pm and 6:00 am. Twenty-two percent of patients required surgical intervention by craniotomy/craniectomy, and 4% required intracranial pressure monitor placement. Average intracranial hemorrhage volume was 17.8 cc (trace to 125). Volume of hemorrhage was associated with the need for an intensive care unit (ICU) stay (odds ratio [OR] = 1.01; p = 0.04), need for surgical intervention (OR = 1.007; p = 0.0001), and mortality (1.816; p < 0.001) and trended toward, but did not reach significance for, overall poor outcome (OR = 1.63; p = 0.06). Sixty-two percent of this patient pool required ICU admission. Average length of ICU stay was 3.5 days (0-35), and average length of hospital stay was 8.3 days (0-82). Mortality in this series was 8%. Lower admission Glasgow Coma Scale (OR = 0.974; p < 0.001) and increased volume of hemorrhage (OR = 1.816; p < 0.001) were associated with increased risk of mortality in the linear regression analysis. Electric scooters have become prevalent in most urban centers, and accidents are a potential source of severe intracranial injury requiring extended ICU and hospital stays, surgical intervention, and sometimes resulting in long-term morbidity and/or mortality. Injuries often occur in the evening hours and are often associated with alcohol/drug use and lack of helmet use. Policy changes to help mitigate the risk of these injuries are recommended.
