NRS2002、MNA和MNA-SF评价老年患者营养状况

NRS2002,MNA and MNA-SF were used to evaluate the nutritional status of elderly patients

目的采用营养风险筛查(NRS2002)、微型营养评估表(MNA)、微型营养评定简表(MNA-SF)对某医院老年医学科新入院老年患者进行营养风险筛查,以明确老年患者营养风险现状和营养筛查工具的适用性,为基层医院临床营养筛查提供科学证据。方法采用连续定点抽样方法,收集患者一般信息,使用NRS2002、MNA、MNA-SF对老年医学科新入院患者进行营养风险筛查,并收集患者血生化检验等指标,分析评分结果。结果①使用NRS2002、MNA、MNA-SF评估170例老年患者,有营养风险或存在营养不良的患者分别为61例(35.9%)、75例(44.1%)、80例(47.1%)。MNA评价结果与NRS 2002和MNA-SF基本一致,Kappa值分别为0.611和0.763(P<0.001)。②以MNA评分结果为标准,绘制NRS2002、MNA-SF的ROC曲线,AUC(Area Under ROC Curve)分别为0.799和0.885,灵敏度分别为0.905和0.863,特异性分别为0.693和0.907,Youden指数分别为0.598和0.807。结论内科老年住院患者入院时约一半存在营养风险,NRS 2002、MNA和MNA-SF均可用于内科老年患者营养状况筛查。

Objective To identify the nutritional risk status of elderly patients and the applicability of nutritional screening tools by using nutritional risk screening(NRS2002),mini nutritional assessment(MNA)and Short-form mini-nutritional assessment(MNA-SF)to provide scientific evidence for clinical nutritional screening in primary hospitals.Methods The general information of patients was collected by continuous fixed-point sampling method.Nutritional risk screening of newly admitted geriatrics patients was conducted using NRS2002,MNA and MNA-SF,and indicators such as blood biochemical test were collected to analyze the scoring results.Results①NRS2002,MNA and mna-sf were used to evaluate 170 elderly patients,among whom 61(35.9%),75(44.1%)and 80(47.1%)were at nutritional risk or malnutrition,respectively.MNA evaluation results were basically consistent with NRS 2002 and MNA-SF,and Kappa values were 0.611 and 0.763(P<0.001),respectively.②The Area Under ROC Curve(AUC)of NRS2002 and MNA-SF was 0.799 and 0.885,respectively,using the MNA score as the standard.The sensitivity was 0.905 and 0.863,respectively.The specificity was 0.693 and 0.907,respectively.The Youden index was 0.598 and 0.807,respectively.Conclusion About half of the medical elderly inpatients present nutritional risk at admission.NRS 2002,MNA and MNA-SF can be used to screen the nutritional status of medical elderly patients.
