This is a single centre longitudinal cohort feasibility pilot study of patients with decompensated alcoholic liver disease. We aim to recruit 125 consecutive patients with decompensated alcoholic liver disease over an 18 month period. This number is based upon approximately 10 admissions per month to acute liver services with decompensated alcoholic liver disease and includes a presumed 20% dropout rate during follow up, giving a total cohort of 100 patients. Patients will undergo a maximum of 6 months follow up following study recruitment.
