“…Passive, subjective observation of active SES riders by the authors in our city, as well as other urban settings, supports these findings [5]. Although Trivedi et al reported a 4.8% prevalence rate of alcohol intoxication, the findings from our cohort (14.6%) better align with the intoxication rate of 16% published by Badeau et al (16%) [5,11].…”

“…Injuries have more frequently occurred during the afternoon and evening hours on weekends when SESs see the most use [5,9]. Although studies have reported rates of helmet use ranging between 0% and 6.3%, the true rate remains elusive, as all studies have been retrospective and have admitted varying degrees of incomplete documentation [5,[9][10][11]. Passive, subjective observation of active SES riders by the authors in our city, as well as other urban settings, supports these findings [5].…”

“…Since their introduction to American public transportation in Southern California, SESs have increasingly gained public approval [5,[9][10][11]. This is largely due to the eco-friendly, convenient, and affordable nature of SESs.…”

“…Additionally, the ubiquitous availability of SESs in urban settings coupled with the ability to arbitrarily "park" SESs on sidewalks has catalyzed their acceptance in the public's view. However, with this increased availability and use, the presumed public safety hazard has gained substantial evidence due to nonadherence to traffic laws, helmet usage, age restrictions, and operation while intoxicated [5,[9][10][11]. The authors predict that as the popularity of SESs continues to rise, safety issues and injuries will also increase proportionally.…”

“…The results of our investigation validate those of recent SES trauma reports. The demographics have consistently shown a 50% -60% male predominance, with an average age of early-to mid-30s [5,[9][10][11]. Racial distribution has only been analyzed by Aizpuru et al, who reported a slight white predominance (54.8%) across a nationwide database system [10].…”

Standing motorized scooters are increasingly used for personal transportation, 1 yet such devices confer considerable risk for trauma, particularly to the head and extremities. 2-5 As potential dangers are not widely known and training is often minimal, riders may often use these devices in an unsafe manner, eg, without protective gear and/or while intoxicated. 2 This single-center study assessed the incidence and severity of traumatic injuries associated with motorized scooters and the associated use of protective devices and/or intoxicants. Methods Following HonorHealth Institutional Review Board approval, a retrospective, single-institution, crosssectional study via review of deidentified medical records (deemed exempt from informed consent

ImportanceElectric scooter (e-scooter) crashes have become a serious health issue worldwide. The need for effective e-scooter regulations has been established in numerous instances.ObjectiveTo investigate the association of restrictions on top speed and nighttime usage on the incidence of e-scooter–related injuries.Design, Setting, and ParticipantsA retrospective comparative cohort study of all patients with an injury related to shared e-scooter riding sustained in Helsinki, Finland. Data were collected from the electric patient database from 3 trauma hospitals representing all public hospitals treating patients with acute trauma in Helsinki. Shared e-scooter injuries from 2 periods were compared: an unrestricted period (January 1 to August 31, 2021) and a restricted period (January 1 to August 31, 2022). Data were analyzed from September 2022 to September 2023.ExposuresThe restrictions established for shared e-scooters during the restricted period were: (1) the daytime top speed of 20 km/h, as opposed to the previous top speed of 25 km/h, (2) the use of shared e-scooters was prohibited on Friday and Saturday nights between 12 am and 5 am, and (3) the nighttime top speed was decreased to 15 km/h from Sunday to Thursday between 12 am and 5 am, as opposed to 25 km/h.Main outcomeThe incidence of e-scooter injuries compared with the total trips made by e-scooters.ResultsThere were 528 e-scooter injuries requiring hospital care during the unrestricted period and 318 injuries during the restricted period of similar length. The median (IQR) age of the patients in the study periods was 25 (21-32) and 28 (22-37), respectively; 308 (58%) and 191 (60%) were male, respectively. The incidence of e-scooter injuries was 19 (95% CI, 17-20) for every 100 000 rides during the unrestricted period and 9 (95% CI, 8-10) per 100 000 rides during the restricted period. In the risk analysis, the odds ratio for shared e-scooter injuries was 0.5 (95% CI, 0.4-0.6) for the restricted period when adjusted for hourly temperature, rain amount, wind speed, and visibility. After introducing the restrictions, the number of e-scooter injuries decreased significantly between 11 pm and 5 am.Conclusion and RelevanceThe number of injuries decreased after implementing restrictions on the top speed and nighttime usage of e-scooters. Similar restrictions in cities with shared e-scooter services should be explored.
