1514 Higher Mortality in Pelvic Acetabular Fractures Is Associated with Lower Body Mass Index

Abstract Aim Fractures of the pelvis and acetabulum can be life-threatening or life changing injuries. Multiple factors contribute to outcome including age, frailty, baseline nutritional status. The aim this study was identify if low BMI (<18.5) a predictor for patients with such injuries in terms morbidity mortality. Method We retrospectively analysed 1033 pelvic acetabular fractures referred single level 1 major trauma centre over 4.5-year period (August 2015 - January 2020). Of these patients, 569 were admitted included our analysis. Data collected on demographics, injury pattern, operative intervention, complications. Comparison made between that underweight (BMI<18.5) not, in-hospital post discharge complications pulmonary embolus (PE), deep venous thrombosis (DVT), ileus, infection, loss reduction mortality at 6 months. Results Underweight had statistically significant increase both (p = 0.019) months 0.039) when compared other groups. No statistical significance found groups comparing morbidity: DVT 0.712), PE 0.736) nor ileus 0.149). Covariate analysis showed associated 3 times increased after correction age energy (adjusted OR 3.028, 95% CI 1.059-8.659). Conclusions This suggests who are underweight. Surgeons should consider findings initiating appropriate peri-operative optimisation patients.
