Abstract
BackgroundSnowmobiling is a popular activity that leads to geriatric trauma admissions; however, this unique trauma population is not well characterized. We aimed to compare the injury burden and outcomes for geriatric versus nongeriatric adults injured riding snowmobiles. Materials and methodsA retrospective cohort study was performed using the National Trauma Databank comparing nongeriatric (18-64) and geriatric adults (≥65) presenting after snowmobile-related trauma at level 1 and 2 trauma centers from 2011 to 2015. Demographic, admission, injury, and outcome data were collected and compared. A multivariate logistic regression model assessed for risk factors associated with severe injury (Injury Severity Score >15). Analysis was also performed using chi square, analysis of variance, and Kruskal–Wallis testing. ResultsA total of 2471 adult patients with snowmobile trauma were identified; 122 (4.9%) were geriatric. Rates of severe injury (Injury Severity Score >15) were similar between groups, 27.5% in geriatric patients and 22.5% in nongeriatric adults (P = 0.2). Geriatric patients experienced higher rates of lower extremity injury (50.4 versus 40.3%, P = 0.03), neck injury (4.1 versus 1.4%, P = 0.02), and severe spine injury (20.6 versus 7.0%, P = 0.004). Geriatric patients had longer hospitalizations (5 versus 3 d, P < 0.0001), rates of discharge to a facility (36.8% versus 12%, P < 0.0001), and higher mortality (4.1 versus 0.6%, P < 0.0001). Geriatric age did not independently increase the risk for severe injury. ConclusionsGeriatric age was not a significant predictor of severe injury after snowmobile trauma; however, geriatric patients suffered unique injuries, had longer hospitalizations, had higher rates of discharge to a facility, and had higher mortality. Tailored geriatric care may improve outcomes in this unique sport-related trauma population.
