Prognostic scores for cirrhotic patients admitted to an intensive care unit: which consequences for liver...

Area of Science:

• Hepatology
• Critical Care Medicine
• Prognostic Score Development

Background:

• Cirrhotic patients admitted to the ICU face elevated mortality risks regardless of the admission cause.
• Existing prognostic scores (liver-specific, general, organ failure) have limitations in predicting outcomes for critically ill cirrhotic patients.
• Organ failure scores are generally superior predictors of outcome in this population.

Purpose of the Study:

• To evaluate the utility of prognostic scores in critically ill cirrhotic patients.
• To address the dilemma of organ allocation for cirrhotic patients with acute organ failure.
• To introduce and validate the CLIF-SOFA score for improved mortality prediction and liver transplantation (LT) candidacy assessment in ICUs.

Main Methods:

• Review and comparison of various prognostic scores: CTP, MELD, SAPS II, APACHE, OSF, SOFA.
• Analysis of the influence of acute disease and underlying cirrhosis on score components.
• Introduction of the CLIF-SOFA score by the EASL-CLIF Consortium, redefining SOFA with cirrhotic-specific cut-offs.

Main Results:

• Organ failure scores, particularly SOFA, are identified as key predictors of outcome in cirrhotic ICU patients.
• The standard SOFA score predicts a higher risk of death for patients awaiting LT but not necessarily worse post-LT outcomes.
• The CLIF-SOFA score is proposed as an ideal ICU score due to its focus on organ failures with specific cut-off values for cirrhotic patients.

Conclusions:

• Accurate identification of cirrhotic patients who will benefit most from LT is crucial.
• The CLIF-SOFA score offers a promising approach for prognostication and LT selection in critically ill cirrhotic patients.
• Further validation of the CLIF-SOFA score in ICU settings is necessary to confirm its utility in guiding LT decisions.
