This study aims at calculating a specific score to cirrhotic patients admitted at ICU (ICCO score) and use this score to predict mortality and outcome for admitted patients.

Liver cirrhosis is the final stage of chronic liver disease. It is characterized by an irreversible replacement of liver parenchyma with fibrotic tissue and regenerative nodules. The major causes of cirrhosis include hepatitis B virus and hepatitis C virus infection, alcohol-associated liver disease (ALD), and non-alcoholic fatty liver disease (NAFLD).

The prognosis of cirrhotic patients admitted to the ICU remains poor It was reported that the mortality rate of patients with cirrhosis admitted to an intensive care unit (ICU) due to organ dysfunction ranges from 34% to 69% depending on the cause of admission, the presence of organ failure (OF) and the severity of the underlying liver disease.

Several prognostic scoring systems have been used to assess patients with cirrhosis admitted to the ICU, general ICU mortality risk scores; such as the Sequential Organ Failure Assessment (SOFA) score and the Acute Physiology and Chronic Health Evaluation II (APACHE II) score, other liver specific scores such as Model of end stage liver disease (MELD) score.

These scores can be calculated immediately upon admission to the ICU (first 24 h) or during the first days of hospitalization, leading to an evolutionary assessment over this short period of time.

Intensive care cirrhotic outcome (ICCO) score is a new score that was introduced to predict mortality and ICU outcome in cirrhotic patients admitted to the ICU. with limited studies that test the validity of the score and compare it with the other well-known ICU scores.

In clinical practice, it remains controversial to determine which score is better at predicting overall mortality, this is due to that Each score is calculated according to its own criteria, and only data obtained within the first 24 hours of the first ICU admittance is used.

In this study investigators will test the validity of ICCO score and compare it with other different ICU scores to find out the most useful score in early prediction of ICU outcome for cirrhotic patients.

Inclusion Criteria:

• Adult patients (age ≥18 years) with cirrhosis admitted to the ICU.
• Confirmed diagnosis of cirrhosis based on clinical, radiological, and/or histological criteria.
• Need for intensive care management due to acute illness or complications related to cirrhosis.

Exclusion Criteria:

• Patients without a confirmed diagnosis of cirrhosis.
• Patients with acute liver failure not meeting criteria for cirrhosis.
• Patients with incomplete data for calculating ICCO.
• Patients transferred from another ICU.
• Patients who refuse participation in the study.
