Research ArticleThe impact of organ dysfunction in cirrhosis: Survival at a cost?

Background & AimsThe incidence of cirrhosis and subsequent development of organ dysfunction (OD) requiring intensive care unit (ICU) support is rising. Historically, critically ill cirrhotics are perceived as having poor prognosis and substantial cost of care.MethodsThe aim was to prospectively analyse resource utilisation and cost of a large cohort of patients (n = 660) admitted to a Liver ICU from 2000 to 2007 with cirrhosis and OD. Child Pugh, MELD, SOFA, APACHE II, and organ support requirements were collected. The Therapeutic Intervention Scoring System (TISS) score, a validated tool for estimating cost in ICU, was calculated daily. Logistic regression was used to determine independent predictors of increased cost.ResultsAlcohol was the most common etiology (47%) and variceal bleeding (VB) the most common reason for admission (35%). Invasive ventilatory support was required in 74% of cases, vasopressors in 49%, and 50% required renal replacement therapy. Forty-nine per cent of non-transplanted patients survived to ICU discharge. Median TISS score and ICU cost per patient were 261 and €14,139, respectively. VB patients had the highest survival rates (53% vs. 24%; p <0.001) and lower associated cost. A combination of VB (OR 0.48), need for ventilation (OR 2.81), low PO2/FiO2 on admission (OR 0.97), and lactate (OR 0.93) improved cost prediction on multivariate analysis (AUROC 0.7; p <0.001) but organ failure scores per se were poor predictors of cost.ConclusionsPatients with cirrhosis and OD result in considerable resource expenditure but have acceptable hospital survival. Further health economic assessment and outcome prediction tools are required to appropriately target resource utilisation.
