Association of Blood Urea Nitrogen to Albumin Ratio with One-Year Mortality Following Hip Fracture Surgery in Elderly Patients: A Retrospective Cohort Analysis

1

The study evaluated the association between blood urea nitrogen to albumin ratio (BAR) and 1-year mortality after hip fracture surgery in elderly patients.
2

A total of 521 patients aged 60 years or older were included, with a 1-year mortality rate of 14.8% observed in the cohort.
3

Logistic regression analysis indicated that higher BAR was significantly associated with increased risk of 1-year all-cause mortality after hip fracture.
4

The area under the receiver operating characteristic curve (AUC) for BAR was 0.67, indicating moderate predictive performance.
5

The study suggests that BAR may serve as a simple indicator for risk stratification in older patients following hip fracture surgery.
