Predictors of outcome in decompensated liver disease: validation of the SOFA-L score

A growing number of patients with liver disease are being referred for critical care support. We have recently shown that a combination of lactate and SOFA score (SOFA-L score) may provide an accurate, objective measurement of prognosis in a group of patients admitted to ICU with alcoholic liver disease. This score has not been validated in an independent patient cohort. A retrospective study was performed where patients admitted to our ICU with decompensated liver disease (any cause) were included. The SOFA-L score accurately predicted in-hospital mortality in this group of patients with an area under the ROC curve of 0.83. Sensitivity and specificity were 65% and 87% respectively SOFA-L performed superior to SOFA, MELD and MELD-Na scores. This study validates the use of the SOFA-L score in the initial 24 hours of ICU admission as an accurate predictor of mortality in this group of patients with a high mortality.
