Diuretic Efficiency Index (DEI) Calculator

Diuretic Efficiency Index (DEI): Explanation and Clinical Context Diuretic Efficiency Index (DEI) quantifies the effectiveness of loop diuretics by relating the change in patient weight (ΔWeight, representing fluid loss) to the administered diuretic dose (furosemide equivalent in mg). It is primarily used in patients with acute decompensated heart failure to assess diuretic response and guide therapy adjustments. A higher DEI indicates effective fluid removal relative to the diuretic dose, whereas a lower DEI may suggest diuretic resistance, which is associated with worse clinical outcomes.

DEI can help clinicians personalize diuretic therapy, monitor response, and predict short-term outcomes in hospitalized heart failure patients.
