BackgroundGeriatric patients face disparities in prehospital trauma care. We hypothesized that geriatric trauma patients are more likely to experience prolonged prehospital scene time than younger adults. MethodsRetrospective analysis of the 2017 National Emergency Medical Services Information System. Patients who met anatomic or physiologic trauma criteria based on national triage guidelines were included (n = 16,356). Geriatric patients (age≥65, n = 3594) were compared to younger adults (age 18–64). The primary outcome was prolonged scene time (>10 min). Multivariable logistic regression was performed, controlling for patient demographics, on-scene treatments, and injury severity. ResultsGeriatric patients were more likely to experience prolonged scene time than younger adults after controlling for other factors (OR 1.78, 95% CI 1.57–2.04, p < 0.001). The likelihood of prolonged scene time reached OR 2.29 (95% CI 1.85–2.84) for patients age 70–79 and OR 2.66 (95% CI 2.07–3.42) for patients age 80–89, relative to age 18–29. ConclusionsGeriatric trauma patients are more likely than younger adults to have prolonged prehospital scene time. This disparity may be caused by delayed recognition of injury severity or age-related cognitive biases.
