摘要
目的:采用主观全面评定法(SGA),营养风险评估2002(NRS 2002),营养不良通用筛查工具(MUST)和微型营养评定简表(MNA-SF),对住院病人进行评估,以确定营养风险筛查工具的临床适用性。方法:对856例住院病人在入院后48 h内采用4种营养筛查工具进行营养筛查,以MNA简表为标准,绘制其他3种营养筛查工具的ROC曲线及曲线下面积(AUC),评估其特异性、灵敏度和Youden指数。结果:使用MUST、SGA、NRS 20002以及MNA-SF进行评估,营养不良或存在营养不良风险的检出率分别为13.3%,13.6%,49.5%和56.0%。以MNA-SF为标准,绘制SGA、NRS 2002和MUST的ROC曲线,AUC分别为0.616、0.809和0.715,灵敏度分别为23.8%、74.5%和46.8%;特异性分别为99.5%、87.3%和96.3%;Youden指数分别为0.233、0.618和0.431。结论:4种营养筛查工具中,NRS 2002的灵敏度和正确性最高,建议病人入院时采用NRS 2002进行营养筛查。
Objective： To evaluate the effectiveness of SGA,NRS 2002,MUST and MNA-SF by evaluating the nutritional status of inpatients. Methods： We used SGA,NRS 2002,MUST,and MNASF to assess the nutritional status of 856 inpatients,with MNA-SF as the reference method for drawing ROC and assessing the AUCs,sensitivities,specificities,and Youden indexes of the other 3 nutritional screening tools. Results： The prevalence of malnutrition varied greatly based on different NSTs（ 13. 3% by MUST,13. 6% by SGA,49. 5% by NRS 2002,and 56. 0% by MNA-SF）. With the MNASF as the standard,the AUCs of SGA,NRS 2002 and MUST were 0. 616,0. 809 and 0. 715,and the sensitivities were 23. 8%,74. 5% and 46. 8%,and the specificities were 99. 5%,87. 3% and 96. 3%,and the Youden indexes were 0. 233,0. 618 and 0. 431,respectively. Conclusion： NRS 2002 has the highest AUC,sensitivity and Youden index. It is recommended to perform NRS 2002 at admission.
