ABSTRACT
Objective:To study the evaluation method of protein energy wasting (PEW) in maintenance hemodialysis patients.Methods:A total of 166 maintenance hemodialysis patients were selected. Their medical records, physical indicators, as well as NS2002, PG-SGA, and MUST nutrition scale scores were also collected. The patients were divided into PEW and non-PEW groups according to whether PEW occurred or not, and the differences in each index between the two groups were compared to analyze the diagnostic efficacy of each index and nutrition score scale results on the occurrence of PEW.Results:The differences in body mass, body mass index(BMI), body surface area, abdominal circumference, triceps skinfold thickness, upper arm circumference, and calf circumference between the PEW and non-PEW groups were statistically significant(all P<0.05). The diagnostic efficacy of a single physical index or nutrition score for PEW was limited. A simplified formula for the PEW risk was obtained by logistic model analysis. The formula had a sensitivity of 67.7% and a specificity of 94.4% for the diagnosis of PEW, as analyzed by the subject's working characteristic curve. Conclusions:Four indicators, including abdominal circumference, primary hand grip strength, BMI, and upper arm circumference, can be combined to comprehensively assess the presence of PEW to improve the diagnostic efficacy of the occurrence of malnutrition in maintenance hemodialysis patients.
