Clinical Scorecard: BAR Could Predict Death After Hip Fracture
At a Glance
Category Detail
Condition Hip Fracture
Key Mechanisms Blood urea nitrogen-to-albumin ratio (BAR) reflects metabolic stress, renal perfusion, and nutritional status.
Target Population Patients aged 65 years and older undergoing surgery for intertrochanteric femur fractures.
Care Setting Single-center surgical setting.
Key Highlights
Higher preoperative BAR associated with increased 30-day mortality. 10.5% of patients died within 30 days post-surgery. BAR value of 9 or greater linked to 2.7 times the odds of mortality. BAR showed 79% sensitivity and 72% specificity for predicting mortality. Other biomarkers did not remain independently associated with mortality.
Guideline-Based Recommendations
Diagnosis
Utilize BAR as a preoperative risk stratification tool.
Management
Monitor BAR values in elderly patients with hip fractures.
Monitoring & Follow-up
Assess metabolic stress and nutritional status through BAR.
Risks
Consider potential confounding factors such as hydration status and frailty.
Patient & Prescribing Data
Elderly patients (65+) with intertrochanteric hip fractures.
Preoperative BAR can guide clinical decision-making and risk assessment.
Clinical Best Practices
Incorporate BAR measurement in preoperative evaluations. Use BAR in conjunction with clinical judgment for patient management.
