UKELD Score: Clinical Guide

Overview

Calculates the UK Model for End-Stage Liver Disease score.

Clinical Significance

Used in the UK to support liver transplant assessment; thresholds require current policy context.

When to Use

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

How It Is Calculated

• UKELD = 5.395 ln(INR) + 1.485 ln(creatinine) + 3.13 ln(bilirubin) − 81.565 ln(sodium) + 435.

Interpretation

• Used in the UK to support liver transplant assessment; thresholds require current policy context.

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.
