Study population: Cirrhotic patients who are at least 18 years old at their first ICU admission in Al-Rajhy University Hospital (according to the established admission policy) and stay more than 24 h will be included.

Brief summary: 1. Determine in-hospital and 28-days mortality rates of critically-ill cirrhotic patients admitted to ICU
2. Evaluate the role of (blood lactate level, lactate/albumin ratio, lactate/bilirubin index and MELD-lactate score) in prediction of mortality compared to other non- lactate containing scores.
3. Study predictors of in-hospital and 28-mortality in these patients.

Detailed description: Liver cirrhosis is a major health problem, which causes high mortality and economic burden worldwide. A large number of liver cirrhosis patients are prone to acute decompensation with organ failure, thus leading them to be admitted to intensive care unit (ICU).

Though liver cirrhosis patients have improved outcomes in ICU over the past decade, the prognosis for those patients remains poor, with in-hospital mortality. Assessment of prognosis, especially in patients with cirrhosis at the ICU, is of importance in order to guide therapeutic measures and improve their outcome.

Many prognostic scores are used to help predicting complications, expected survival and estimate the risk of various medical interventions in these patients as CTP, MELD, CLIF-C OF, CLIF-C AD and CLIF-C ACLF scores. Although these models are non-invasive, they have certain deficiencies as they don't consider other conditions that are associated with poor prognosis as poor tissue perfusion in critically-ill cirrhotic patients.

Lactate is a marker of metabolic changes resulting from tissue hypoxia or stress caused by the release of adrenaline. It was used to improve the prediction of short-term mortality of critically ill patients at ICU. Little is known about role of blood lactate in prediction of prognosis of critically ill Egyptian cirrhotic patients at ICU. Therefore, the investigators will conduct their study to shed some light on this topic.

Eligibility criteria: Inclusion Criteria:

* Cirrhotic patients who are at least 18 years old at their first ICU admission in Al-Rajhy University Hospital (according to the established admission policy) and stay more than 24 h will be included.

Exclusion Criteria:

* 1) Patients admitted for liver transplantation.
* 2) Patients whose blood lactate data is lost at 24 hours from ICU admission.
* 3) Patients taking drugs that increase level of serum lactate as metformin , acetaminophen, linezolid, epinephrine, beta2 agonists, propofol, nucleoside reverse transcriptase inhibitors (NRTIs) as lamivudine and abacavir , and theophylline
