Analyses of outcomes after acute liver failure (ALF) have typically included all ALF patients regardless of whether they were listed for liver transplantation (LT). We hypothesized that limiting analysis to listed patients might provide novel insights into factors associated with outcome, focusing attention on disease evolution after listing. Listed adult ALF patients enrolled in the US Acute Liver Failure Study Group registry between 2000 and 2013 were analyzed to determine baseline factors associated with 21-day outcomes after listing. We classified 617 patients (36% of overall ALF group) by 3-week outcome after study admission: 117 were spontaneous survivors (SSs; survival without LT), 108 died without LT, and 392 underwent LT. Only 22% of N-acetyl-p-aminophenol (APAP) ALF patients were listed; however, this group of 173 patients demonstrated greater illness severity: higher coma grades and more patients requiring ventilator, vasopressor, or renal replacement therapy support. Only 62/173 (36%) of APAP patients received a graft versus 66% for drug-induced liver injury patients, 86% for autoimmune-related ALF, and 71% for hepatitis B-related ALF. APAP patients were more likely to die than non-APAP patients (24% versus 17%), and the median time to death was sooner (2 versus 4.5 days). Despite greater severity of illness, the listed APAP group still had a SS rate of 40% versus 11% for non-APAP causes (P

Functional outcomes for long-term survivors of acute liver failure (ALF) are not well characterized. The aim of this prospective study was to determine health-related quality of life in long-term adult ALF survivors. Acute Liver Failure Study Group registry participants completed the Centers for Disease Control and Prevention Health-Related Quality of Life 14 and Short Form 36 (SF-36) questionnaires at 1- and/or 2-year follow-up study visits. Responses were compared among ALF subgroups and to those for available general US population controls. Among the 282 adult ALF patients, 125 had undergone liver transplantation (LT), whereas 157, including 95 acetaminophen overdose (APAP) patients and 62 non-APAP patients, were spontaneous survivors (SSs). APAP SS patients reported significantly lower general health scores and more days of impaired mental and physical health, activity limitations due to poor health, pain, depression, and anxiety in comparison with the other groups (P ≤ 0.001). There were no significant differences in coma grade or in the use of mechanical ventilation or intracranial pressure monitoring among the patient groups during their ALF hospitalization, but APAP SSs had significantly higher rates of psychiatric disease and substance abuse (P
