PURPOSE:
To assess risk factors and associated outcomes of acute kidney injury (AKI) in hip fracture patients.

METHODS:
Risk factors for AKI were identified by multivariate logistic regression. AKI patients were matched to patients who did not experience AKI using a validated trauma triage score. Comparative analyses between matched groups were performed.

RESULTS:
Risk factors of AKI included increasing Charlson Comorbidity Index and use of anticoagulation medications. AKI was associated with increased likelihood of medical complications and longer, more costly hospital stays.

DISCUSSION:
Patients with identified risk factors for AKI may benefit from consultation with nephrology and closer lab monitoring.
