Surgery for a fracture of the hip within 24 hours of admission is independently associated with reduced short-term post-operative complications

Aims We aimed to characterise the effect of expeditious hip fracture surgery in elderly patients within 24 hours of admission on short-term post-operative outcomes. Patients and Methods Patients age 65 or older that underwent surgery for closed femoral neck and intertrochanteric hip fractures were identified from the American College of Surgeons National Surgical Quality Improvement Program between 2011 and 2014. Multivariable propensity-adjusted logistic regressions were performed to determine associations between early surgery within 24 hours and post-operative complications, controlling for selection bias in patients undergoing early surgery based on observable characteristics. Results A total of 26 051 patients were included in the study; 5921 (22.7%) had surgery within 24 hours of admission, while 20 130 (77.3%) patients had surgery after 24 hours. Propensityadjusted multivariable logistic regressions demonstrated that surgery within 24 hours was independently associated with lower odds of respiratory complications including pneumonia, failure to extubate, or reintubation (odds ratio (OR) 0.78, 95% confidence interval (CI) 0.67 to 0.90), and extended length of stay (LOS) defined as >= 6 days (OR 0.84, 95% CI 0.78 to 0.90). Conclusion In elderly patients with hip fractures, early surgery within 24 hours of admission is independently associated with less pulmonary complications including pneumonia, failure to extubate, and reintubation, as well as shorter LOS.
