MELD-XI Score: Clinical Guide

Overview

Calculates MELD-XI where INR is unavailable or unsuitable.

Clinical Significance

Higher scores indicate worse prognosis in populations where INR is excluded.

When to Use

• Use as decision support when all required inputs are reliable.

How It Is Calculated

• MELD-XI = 5.11×ln(bilirubin) + 11.76×ln(creatinine) + 9.44.

Interpretation

• Higher scores indicate worse prognosis in populations where INR is excluded.

Worked Example

Enter verified values in the displayed units; MedicalC applies the published equation or point system.

Limitations

• Prediction models may be miscalibrated outside their derivation population.
• Measurement and classification error can materially change the result.

Clinical Pearls

• Document source values and units with the result.
• Use trends and the full clinical picture.

Common Mistakes

• Wrong units.
• Using non-contemporaneous inputs.
• Treating the output as a diagnosis or mandatory treatment decision.
