摘要
目的 明确传统营养评价方法、简易营养评价精法及营养不良筛查方案在老年住院患者中的应用.方法 应用3种营养筛查工具对老年病房100例患者进行营养筛查,用敏感性、特异性、受试者工作特征曲线和人体测量仪判定结果对3种营养筛查工具评定结果进行分析比较.结果 体质量指数、微型营养评价精法和营养不良筛查方案3种营养筛查工具对营养不良的筛出率分别为7%(7/100)、58%(58/100)、39%(39/100);以人体测量仪检测结果为标准,3种营养评价工具的灵敏度分别为0.475、0.918、0.410,特异度分别为0.615、0.103、0.641;3种工具串联试验灵敏度为0.557,特异度为0.913;并联试验灵敏度为0.929,特异度为0.435.结论 在筛查老年患者营养不良的应用中,3种营养评定工具灵敏度差异显著.以营养不良筛查方案准确性最高,3种工具联合使用效果更好.
Objective To identify the applicability of Traditional nutritional evaluation method,short-form mini-nutritional assessment (MNA-SF) and nutrition risk screening 2002 (NRS 2002) on screening malnutrition in elderly in-patients.Methods 100 elderly in-patients with malnutrition were screened by the above screening instruments.The evaluation effects of the 3 methods were compared by sensitivity,specificity and ROC curve.Results The detection rates of elderly in-patients with malnutrition by BMI,MNA-SF and NRS 2002 was 7%,58% and 39% respectively.Taking the human body measurement instrument as standard,the sensitivities of BMI,MNA-SF and NRS 2002 was 0.475,0.918 and 0.410respectively,the specificities was 0.615,0.103 and 0.641 respectively.3 tools series test sensitivity and specificities was 0.557 and 0.913 respectively,parallel test sensitivity and specificities was 0.929 and 0.435 respectively.Conclusions There is significant difference among the sensitivities of the 3 methods,NRS 2002 has the highest accuracy and is applicable to the screening of nutrition risks in elderly patients.Combined 3 kinds of tool can better improve the effect.
