The goal was to investigate if patient characteristics can be used to predict 1-year post-fracture mortality after pelvic fracture. Multivariate logistic regression identified male gender, comorbidities and presence of in-hospital complications as predictors of 1-year mortality.
Purpose: Osteoporotic pelvic fractures have significant mortality and morbidity in the older population. The aim of this study was to investigate the factors predicting one-year mortality of patients sustaining a low-impact pelvic fracture (pelvic ring and acetabulum).
Methods: A total of 282 patients aged ≥ 65 years presenting with a low-energy pelvic ring (n =254) or acetabular (n =28) fracture to the emergency department at the University Hospitals Leuven were included. Demographic and clinical data were retrospectively collected and predictors for mortality one year after pelvic ring fractures were evaluated.
Results: The one-year mortality after osteoporotic pelvic ring fractures and acetabular fractures was respectively 20.4% (95% CI 15.7-26.0) and 14% (95% CI 4.0-32.7). Multivariate logistic regression adjusted for confounders identified male gender (OR 3.18; 95% CI (1.06-9.49), p =0.038), a higher number of comorbidities (OR 1.5; 95% CI (1.16-1.95), p =0.002) and in-hospital complications (OR 5.00; 95% CI (1.39-17.97), p =0.014) as independent predictors of one-year mortality after pelvic ring fractures.
Conclusion: The one-year mortality after low-energy pelvic is high and can be predicted by different patient characteristics. These findings can guide pelvis fracture treatment decisions in the older population.
