Application effects of improved nutritional risk screening assessment scale in patients with middle or late stage tumor

Abstract

Objective To explore the adoption of improved nutritional risk screening assessment scale (INRSAS) in nutritional screening of middle or late stage tumor patients. Methods In according with the convenient method, 300 patients with middle or late stage tumor were selected, were monitored nutrition by INRSAS, mini nutritional assessment (MNA), and subjective global assessment (SGA), and measured serum protein and body mass index. Receiver operator characteristic curve (ROC) was utilized to screen tool′s specificity, sensitivity, etc., and the value of Kappa was used to analyze the uniformity. Results After the 300 completed SGA, it showed that the incidence of malnutrition was 54%. Setting SGA as standard, INRSAS′s specificity, sensitivity, positive predicted value, negative predicted value, Kappa value, and Youden index were 0.986, 0.927, 0.986, 0.919, 0.907, 0.910; MNA were 0.781, 0.854, 0.827, 0.842, 0.664, 0.635. Conclusions INRSAS′s specificity, sensitivity, positive predicted value, and negative predicted value are higher than MNA′s, and have a good uniformity with SGA. The assessment method of INRSAS is simple and easily implements which is suitable for nutrition risk screening for patients with middle and late stage.
