Ten years after our team's publication, practices have changed considerably in the management of severe cirrhotic patients. This study will analyse these practices in primary care hospitals and in a tertiary centre, and assess the impact of these changes on the prognosis of these patients. The following hypotheses will be tested: * Improvement in intensive care and overall prognosis compared with data from the literature prior to 2014 * Improved access to liver transplantation compared with the literature prior to 2014 * Improvement in intensive care unit practices (for example: application of recommendations published by learned societies concerning the intensive care unit management of patients with cirrhosis, access to comfort care, degree of clinical severity on admission to the intensive care unit, etc.). * Centre' effect: variability in the phenotype of patients admitted to intensive care depending on the technical facilities available and whether or not the hospital centre has access to TH.
