MELD 3.0 Score: Clinical Guide

Overview

Calculates MELD 3.0 using bilirubin, INR, creatinine, sodium, albumin and sex.

Clinical Significance

Higher scores indicate greater short-term mortality risk and transplant priority.

When to Use

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

How It Is Calculated

• Published MELD 3.0 regression equation with bounded laboratory inputs.

Interpretation

• Higher scores indicate greater short-term mortality risk and transplant priority.

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.
