Analysis of prognostic models for liver failure  

Liver failure progresses rapidly, and patients with this disease are usually in a critical condition. The medical treatment of liver failure has unsatisfactory results, leading to a high mortality. How to accurately judge the prognosis of patients with liver failure according to their clinical manifestations and laboratory test results is a very good guide for clinical treatment strategies and donor liver allocation. The prognostic models for liver failure, such as CTP score, MELD and its derivative scoring system, KCH criteria, SOFA score, APACHE scoring system, SMSVH score, Clichy criteria, and ANN, are reviewed. These models are used to guide the development of clinical treatment strategies and screen out patients eligible for liver transplantation. In addition, the prognostic values of these models for liver failure and their differences are evaluated.
