ABSTRACT
Objective:To compare three nutritional screening tools in predicting dialysis-related pro tein-energy wasting(PEW) among maintenance hemodialysis(MHD) patients and to find a more rapid,accurate,and feasible screening tool.Methods:The nutrtional risk screening 62002 (NRS 2002),7-point subjective global assessment(SGA) and malnutrition inflammation scores (MIS) were compared among 205 MHD patients.Correlations between the serum biochemistry,anthropometry and different screening tools were analyzed,and comparisons were made with established guidelines by International Society of Renal Nutrition and Metabolism (ISRNM) for PEW.Results:A total of 31.2％ of HD patients had PEW by ISRNM criteria,whilst using NRS 2002,7-point SGA and MIS,58％,40.8％ and 46.8％ of MHD patients exhibited PEW respectively.The results of three screening tools were closely related to those by serum biochemistry and anthropometry (P ＜ 0.05),but the composite correlation coefficient between the screening tools for PEW and the objective nutritional index commonly used was higher in NRS 2002(r =0.787,P ＜ 0.001) than in 7-Point SGA or MIS.NRS 2002 had higher sensitivity and accuracy values (87.5％ and 59.1％,respectively) in MHD Patients.Conclusion:MIS,7-PointSGA and NRS 2002 are valid tools for nutrition screening of dialysis patients,and NRS 2002 may be the best one.
