Background: Accurate population-based data are required concerning the rate, economic impact, and long-term outcome from acute on chronic liver failures (ACLF) in hospitalized patients with cirrhosis. We aimed to discover time trends for the epidemiology, economic burden, and mortality of ACLF in Thailand. Methods: We conducted a nationwide, population-based, cohort study which involved all hospitalized patients with cirrhosis in Thailand during the period between 2009 and 2013, with data from the National Health Security Office. ACLF was defined by two or more extrahepatic organ failures in patients with cirrhosis. Primary outcomes were trends in hospitalizations, hospital costs, together with inpatient mortality. Results: The number of ACLF hospitalizations in Thailand doubled between 3185 in 2009 and 7666 in 2013. The average cost of each ACLF hospitalization was 3.5-fold higher than for cirrhosis ($ 1893 versus $ 519). The hospital is paid using a diagnosis-related group (DRG) payment system that is only 15% of the average treatment costs ($ 286 from $ 1893). The in-hospital fatality rate was 51% for ACLF while the additional fatality rate was 85% up to 1 year. The ACLF organ failure trends indicated sepsis with septic shock and renal failure as the majority proportion. Age, the number and types of organ failure and male sex were predictors of ACLF death. Conclusions and relevance: Cirrhosis and ACLF both represent substantial and increasing health and economic burdens for Thailand. These data can assist national health care policy stakeholders to target high-risk patients with cirrhosis for care.
