What is Liver Failure ?

• Cirrhosis

– Fibrosis, Portal hypertension

• Decompensated Liver Disease

– Ascites, varices, renal dysfucntion

• Acute on Chronic Liver Failure

– Acute event with worsening of liver and other organ function

• Acute Liver Failure

– Previously normal liver : acute, hyperacute, subacute

• Post surgical Liver failure

• Liver dysfunction / failure in critically ill patients

• Post trauma liver dysfunction / failure

The American Journal of GASTROENTEROLOGY 2014 McPhail et al

• A SOFA/CLIF-SOFA score of greater than 13 on Day 1

• 90% mortality rate

• SOFA scores greater than 13 on Day 3 and 7

• 89% and 90% mortality rates respectively

• Lactate level greater than 4 mmol/L on Day 1

• 81% mortality rate

• Lactate level greater than 4 mmol/L on day 3 and 7

• 91% mortality rate and 88% mortality respectively

• The absolute SOFA score on day 3 was a better predictor of mortality than change in

score.

• Delta SOFA score changes

• Increase from day 1 : mortality 51%

• Unchanged : mortality of 42%

• Decrease after Day 1 : mortality was 28%.

Incorporation of age and wbc : CLIFF C score

Jalan et al Journal of Hepatology

2014 vol. 61 j 1038–1047

Fixing specificity at 95% and estimating sensitivity (bootstrap

method)

A cut-off value of greater than 14 for CLIF-SOFA gives a sensitivity of

32% (26%– 40%)

A cut-off of greater than 12 for SOFA gives a sensitivity of 33 % (26–

39)

Suggests neither score : SOFA or CLIFF SOFA provide an accurate

indicator of futility.
