Background In-hospital mortality and discharge disposition following traumatic hip fractures previously reported in the literature, has mainly focused on a nationwide scale, which may not be reflective of unique populations. Objective Our aim was to characterize demographics, hospital disposition, and associated outcomes for patients with the most common hip fractures. Methods A retrospective study utilizing the Trauma Registry from the Texas Department of State Health Services. Patient demographics, injury characteristics, and outcomes, such as in-hospital mortality, and discharge dispositions, were collected. The data were analyzed via univariate analysis and multivariate regressions. Results There were 17,104 included patients, composed of 45% femoral neck fractures (FN) and 55% intertrochanteric fractures (IT). There were no differences in injury severity score (ISS) (9 ± 1.8) or age (77.4 ± 8 years old) between fracture types. In-hospital mortality risk was low but different among fracture types (intertrochanteric, 1.9% vs femoral neck, 1.3%, P = .004). However, when controlling for age, and ISS, intertrochanteric fractures and Hispanic patients were associated with higher mortality (P < .001, OR 1.5, 95% CI 1.1-2.0). Uninsured, and Black/African American (P = .05, OR 1.2, 95% CI 1.1-1.3) and Hispanic (P < .001, OR 1.2, 95% CI 1.1-1.3) patients were more likely to be discharged home after adjusting for age, ISS, and payment method. Conclusion Regardless of age, severity of the injury or admission hemodynamics, intertrochanteric fractures and Hispanic/Latino patients had an increased risk of in-hospital mortality. Patients who were uninsured, Hispanic, or Black were discharged home rather than to rehabilitation, regardless of age, ISS, or payment method.
