AARC-ACLF score

The APASL ACLF Research Consortium (AARC) score grades acute-on-chronic liver failure as defined by APASL: jaundice (bilirubin 85 µmol/L or more) and coagulopathy (INR 1.5 or more) complicated within 4 weeks by ascites and/or encephalopathy. Five variables each score 1 to 3.

Grade I is a score of 5 to 7, grade II 8 to 10 and grade III 11 to 15. Short-term mortality rises with the grade. Reassess the score over the first week, as a rising score predicts a worse outcome.
