New Max Verstappen's on the Rise?: Go-Kart Incidents in a Level-I Trauma Center in the Netherlands

Background: Go-karting has become an increasingly popular motorsport and leisure activity among children of all ages. However, go-karting is not without risks. The main purpose of this study was to assess the number of pediatric patients presenting at the emergency department of a level-I trauma center following a go-kart-related injury event over a nine-year period. Additionally, this study aimed to provide a comprehensive overview of patient characteristics, trauma mechanisms, injury types and use of safety devices. Methods: A retrospective single-center cohort study identified all patients that presented at the emergency department from January 2015 to December 2023. Data from the Dutch Nationwide Trauma Registry and medical files were assessed, descriptive statistics were conducted, and cohorts-defined by date-were compared: the first cohort from January 2015 to December 2021, and the second from January 2022 to December 2023, with December 2021 marking the moment when Max Verstappen became the first dutchman to win the Formula One World Driver's Championship. Results: A total of 14 patients were identified, with an incidence rate of respectively 0.86 and 4.0 per year for the cohorts. In the total study population, 86% were male and the mean age was 12 years (range 4-17). Collision was the most common trauma mechanism with velocities even exceeding 70 km/h. Reported use of a helmet and seatbelt were respectively 64% and 29%. The mean Injury Severity Score (ISS) was 8.6 (±8.6). 57% of the patients encountered minor injuries (ISS ≤ 8), encompassing mostly soft tissue injuries, whereas truncal injuries occurred most frequently in moderately (ISS 9-15) and severely (ISS ≥ 16) injured children. Conclusions: This study has found that although the number of cases was relatively low, an increase in injuries was seen after 2021 in go-karting in children. Almost half of patients were seriously injured, requiring admission at the least. Resulting from this, considerations on minimum age for participation, enforcement of the use of safety devices including additional safety measures targeting truncal protection, and more clear laws and regulations are advised.
