Emergency liver transplantation may be indicated and can be the only curativetreatment option. This study aimed to assess the prognostic value of criteria for emergency livertransplantation in predicting 28-day mortality in patients with mushroom-induced acute liver injury.Methods： A retrospective cohort study was performed between January 2005 and December 2015. Alladult patients aged≥18 years admitted with mushroom intoxication at our emergency department wereevaluated. All patients with acute liver injury, defined as elevation of serum liver enzymes （〉5 timesthe upper limit of normal, ULN） or moderate coagulopathy （INR 〉 2.0） were included. The ability of the King’s College, Ganzert’s, and Escudié’s criteria to predict 28-day mortality was evaluated.展开更多
