PURPOSE: To analyze characteristics, accident mechanisms, injury patterns, and treatment of pedelec accidents, focusing on older riders (≥65 years) and those requiring intensive care.
METHODS: This descriptive single-center study included all patients presenting after a pedelec accident at a level I trauma center (January 2017-December 2023). Data included demographics, accident mechanisms, injuries, and treatments. A subgroup analysis was performed for patients requiring intensive care.
RESULTS: Between 2017 and 2023, 103 pedelec riders were injured, with annual cases rising steadily, peaking at 45 in 2023. Patients were predominantly male (57 %) with a mean age of 53 ± 19 years; 30 % were ≥65 years. Helmet use was documented in 34 %, alcohol in 10 %, and anticoagulant therapy in 15 %. Most accidents occurred during warmer months (66 %), in the afternoon (47 %), and were caused by rider errors (36 %) or car collisions (17 %). A total of 229 injuries were recorded (2.2 per patient), mainly affecting the head (33 %) and upper extremities (29 %). Thirty patients (30 %) required surgery, 41 (40 %) were hospitalized, and 11 (11 %) needed ICU care. The predominant reason for ICU admission was severe traumatic brain injury (TBI) with intracranial hemorrhage, present in 91 % of ICU patients. These patients were significantly older (mean 77 ± 13 years; OR 1.11 per year, 95 % CI [1.05-1.20]; p = 0.002), more often on anticoagulants (45 %; OR 5.33, 95 % CI [1.37-20.80]; p = 0.022), and none wore a helmet (0 %; OR 0.07, 95 % CI [0.00-1.23]; p = 0.015, Haldane correction). Males ≥65 years had a 25-fold increased ICU admission risk (OR 25.07, 95 % CI [4.89-128.53]; p < 0.001). Helmet use was associated with a 16.4 % absolute risk reduction (ARR) for ICU admission with a Number Needed to Treat (NNT) of 6. In-hospital mortality was 1.9 %.
CONCLUSION: Pedelec accidents have sharply increased, with injuries to the head and upper extremities most common. Older adults, especially men ≥65, face the highest risk of severe outcomes, including traumatic brain injury requiring ICU admission. Two-thirds of riders did not wear a helmet; helmet use significantly reduced critical injury risk. Focused prevention efforts-particularly promoting helmet use and rider safety education-are urgently needed.
