Abstract: Objective The purpose of this study was to investigate the application of subjective comprehensive assessment (SGA), simple nutritional assessment (MNA) and nutritional risk screening 2002 (NRS2002) in nutritional assessment of patients with decompensated cirrhosis. Methods 98 patients with decompensated liver cirrhosis were admitted to our hospital between January 2017 and January 2018, and the nutritional risk were screened by SGA, MNA and NRS2002 in all the patients. The consistency of the three methods was compared byKappa value. Results The incidence of mild to moderatemalnutrition by MNA was 36.7% and that of severe malnutrition was 30.6%, the incidence of mild to moderate malnutrition by SGA was 30.6% and that of severe malnutrition 2.0%, and the incidence of mild to moderate malnutrition by NRS2002 was 25.5% and that of severe malnutrition was 15.3%; the Kappa value was 0.344(P＜0.05) as regard to the consistence of SGA and MNA, the Kappa valve was 0.476 (P＜0.05) as regard to the consistence of SGA and NRS2002, and the Kappa value was 0.463(P＜0.05) as the consistence of evaluation by MNA and NRS2002 were compared. Conclusion The differences of malnutrition status assessed by different methods in our series might be great, which hints further investigation needed in the future for Objective evaluation in this setting.
