Q: The Model for End-Stage Liver Disease, or MELD, is a scoring system for assessing the severity of chronic liver disease. Formula for MELD score is

MELD = 3.78[Ln serum bilirubin (mg/dL)] + 11.2[Ln INR] + 9.57[Ln serum creatinine (mg/dL)] + 6.43

If patient is already on Dialysis - what value of Creatinine is automatically substituted?

Answer: 4

In interpreting the MELD Score in hospitalized patients, the 3 month mortality is:

• 40 or more — 71.3% mortality
• 30–39 — 52.6% mortality
• 20–29 — 19.6% mortality
• 10–19 — 6.0% mortality
• <9 — 1.9% mortality
