Worsening Renal Function (WRF) Index Calculator

Worsening Renal Function (WRF) Index in Heart Failure: Explanation and Clinical Context The WRF Index predicts the risk of acute kidney injury or worsening renal function in patients hospitalized with acute decompensated heart failure. It uses clinical variables such as age, baseline serum creatinine, systolic blood pressure, and heart rate at admission. Higher predicted probabilities indicate a higher likelihood of renal function deterioration, which is associated with worse outcomes in heart failure patients.

This tool can guide clinicians in monitoring, medication adjustment (e.g., diuretics, ACE inhibitors), and early intervention to prevent renal complications.
