改良版营养风险筛查评估量表在中晚期肿瘤患者中的应用效果

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

目的：探讨改良版营养风险筛查评估量表在中晚期肿瘤患者营养筛查中的适用性。方法采用方便抽样法抽取300例中晚期肿瘤患者,在患者入院24~72 h采用改良版营养风险筛查评估量表、微型营养评定法（ MNA）、主观整体营养评估量表（ SGA）进行营养筛查,同时测量血清蛋白及计算体质量指数（ BMI）。通过受试者工作特征曲线（ ROC）测量筛查工具的特异度、灵敏度等,通过Kappa值分析一致性。结果300例患者均完成营养风险筛查评估,SGA测得患者营养不良发生率为54%。以SGA为金标准,改良版营养风险筛查评估量表的特异度、灵敏度、阳性预测值、阴性预测值、Kappa值及Youden指数分别为0.986,0.927,0.986,0.919,0.907,0.910；MNA分别为0.781,0.854,0.827,0.842,0.664,0.635。结论改良版营养风险筛查评估量表的特异度、灵敏度、阳性预测值、阴性预测值等均高于MNA,与SGA一致性较好,且评估方法简单易行,适用于中晚期肿瘤患者的营养风险筛查。

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.
