AimThe aim of the present study was to examine significant differences in patient characteristics, associated factors and outcomes for indoor versus outdoor falls among trauma patients.MethodsA retrospective cross-sectional study using data from the trauma registry and electronic medical records at a level 1 trauma center in the USA was carried out. People aged 55 years or older, for whom fall location could be identified (n = 712), were included in the study. Demographic information, functional status before admission, comorbid conditions, activation level, Injury Severity Score, discharge disposition and injury type were included in the comparative analyses. Associated factors for falls and fractures in each location were also examined using logistic regression.ResultsSignificant differences were found in patient characteristics between indoor and outdoor fallers. Significant differences in outcomes were found related to discharge disposition and injury type. Open wounds were more common among outdoor fallers (26.5%) as compared with indoor fallers (16.3%, P = 0.002). Although disorders of joints with difficulty walking were associated with fractures among both indoor (OR 7.20, CI 2.19-23.66) and outdoor fallers (OR 5.65, CI 1.27-25.06), sex was only associated with fractures among those who fell indoors (OR 1.69 CI 1.12-2.56).ConclusionsSignificant differences exist in characteristics of indoor and outdoor fallers, and for discharge disposition and injury type for each fall location among patients admitted for trauma care. Factors associated with fractures differ between indoor and outdoor fallers. Results can help to inform targeted primary and secondary prevention initiatives.
