    Abstract:
    Racial and ethnic differences in the presentation and outcomes of patients wait-listed with acute liver failure (ALF) have not been explored. Adult patients with ALF wait-listed for liver transplantation (LT) from 2002 to 2016 were investigated using the United Network for Organ Sharing database. Clinical characteristics and causative etiologies were compared between white, black, Hispanic, and Asian patients with ALF who were wait-listed as status 1. A competing risk analysis was used to explore differences in LT and wait-list removal rates. Kaplan-Meier survival curves were used to explore differences in 1-year posttransplant survival. There were 8208 patients wait-listed with a primary diagnosis of ALF; 4501 were wait-listed as status 1 (55.3% of whites, 64.4% of blacks, 51.6% of Hispanics, 40.7% of Asians; P < 0.001). Black patients had higher bilirubin and Model for End-Stage Liver Disease at wait-listing than other groups. White patients were the most likely to have acetaminophen toxicity as a causative etiology, whereas black patients were the most likely to have autoimmune liver disease. Black patients were significantly more likely to undergo LT than white patients (hazard ratio, 1.20; 95% confidence interval, 1.08-1.30). There was no difference in wait-list removal because of death or clinical deterioration among racial/ethnic groups. The 1-year posttransplant survival was lowest in black patients (79.6%) versus white (82.8%), Hispanic (83.9%), and Asian (89.3%) patients (P = 0.02). In conclusion, etiologies of ALF vary by race and ethnicity. Black patients with ALF were more likely to be wait-listed as status 1 and undergo LT than white patients, but they were sicker at presentation. The 1-year posttransplant survival rate was lowest among black patients.
