Abstract
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 0.410 respectively, 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. Key words: Nutrition assessment; Aged; Malnutrition; Nurtritional screening program
