Impact of Comorbidities on Hospitalization for Injuries in Riders of Electric Bikes and Powered Scooters: A Retrospective Cross‐Sectional Study

Background and Objectives: Injuries associated with electric bikes (E‐bikes) and powered scooters (P‐scooters) have increased yearly worldwide. We aimed to evaluate the impact of pre-existing comorbidities on the probability of hospitalization for injuries in riders of E‐bikes and P‐ scooters. Materials and Methods: A retrospective cross‐sectional study design was used. The cohort included patients referred to the emergency department (ED) of a tertiary medical center in 2014– 2020 for injuries sustained while riding an E‐bike or P‐scooter. Data were collected from the medical files on demographics, clinical characteristics including pre‐existing comorbidities and permanent use of medications, and injury characteristics. Findings were compared between patients referred for hospitalization from the ED and patients discharged home. Results: Of the 1234 patients who met the inclusion criteria, 202 (16.4%) had a prior medical condition and 167 (13.5%) were taking medication on a permanent basis. A significant relationship was found between hospitalization and having a medical condition (x²(1) = 9.20, p = 0.002) or taking medication on a permanent basis (x²(1) = 6.24, p = 0.01). Hospitalization for injuries was more likely in patients with a comorbidity (27.8%) than those without a comorbidity (15.5%), and in patients who were on permanent drug therapy (22.2%) than in patients who were not (12.9%). Surprisingly, anticoagulant intake specifically had no effect on the probability of hospital admission. Conclusions: Patients with comorbidities have a higher incidence of hospitalization for E‐bike‐ and P‐scooter‐associated injuries. Therefore, physi-cians may take into account comorbidities for the effective management of this patient group’s in-juries.
