AST/ALT ratio may predict 1-year mortality in elderly patients operated for femoral neck fracture: Study

This retrospective cohort study analyzed data from 179 elderly patients (≥60 years) who underwent partial hip replacement for femoral neck fracture between January 2019 and December 2021. Results: Of the 179 patients, 29.6% died within one year of surgery. The deceased patients were older, predominantly male, and had higher rates of postoperative complications and transfusions. Univariate analysis identified age, sex, blood type, comorbidities, postoperative complications, transfusions, and laboratory parameters (including AAR, creatinine, and lymphocyte count) as associated with mortality. Multivariate analysis further highlighted advanced age, male sex, blood group A, postoperative transfusions, elevated creatinine levels, and high AAR (>2.1) as independent predictors of mortality.

The findings suggest that preoperative AAR may serve as an independent predictor of mortality in elderly patients undergoing hip fracture surgery, highlighting its potential utility in preoperative risk stratification.
