Data describing long-term outcomes following ICU for patients with alcohol-related liver disease are scarce. We aimed to report long-term mortality and emergency hospital resource use for patients with alcohol-related liver disease and compare this with two comparator cohorts.
Retrospective cohort study linking population registry data.
All adult general Scottish ICUs (2005–2010) serving 5 million population.
ICU patients with alcohol-related liver disease were compared with an unmatched cohort with Acute Physiology and Chronic Health Evaluation defined diagnoses of severe cardiovascular, respiratory, or renal comorbidity and a matched general ICU cohort.
Outcomes were 5-year mortality, emergency hospital resource use, and emergency hospital readmission. Multivariable regression was used to identify risk factors and adjust for confounders. Of 47,779 ICU admissions, 2,463 patients with alcohol-related liver disease and 3,590 patients with severe comorbidities were identified; 2,391(97.1%) were matched to a general ICU cohort. The alcohol-related liver disease cohort had greater 5-year mortality than comorbid (79.2% vs 75.3%; p < 0.001) and matched general (79.8% vs 63.3%; p < 0.001) cohorts. High liver Sequential Organ Failure Assessment score and three-organ support were associated with 90% 5-year mortality in alcohol-related liver disease patients. After confounder adjustment, alcohol-related liver disease patients had 31% higher hazard of death (adjusted hazard ratio, 1.31; 95% CI, 1.17–1.47; p < 0.001) and used greater resource than the severe comorbid comparator group. Findings were similar compared with the matched cohort.
ICU patients with alcohol-related liver disease have higher 5-year mortality and emergency readmission rates than ICU patients with other severe comorbidities and matched general ICU patients. These data can contribute to shared decision-making for alcohol-related liver disease patients.
