老年病科住院患者营养风险筛查和评估

目的：分析营养风险筛查2002（NRS2002）在老年病科住院患者营养风险筛查中的应用情况。方法：利用欧洲营养风险筛查2002（NRS2002）、微型营养评定工具（MNA）及主观全面营养评价法（SGA）对本院老年病科345例住院患者营养风险及住院时间进行评估。结果：NRS2002的灵敏度为84．7％，ROC曲线下的面积（AUC．ROC）为0．899；NRS2002评估有营养不良风险的患者住院时间大于10d的可能性高于无营养不良风险组患者（OR=6．43，95％CI=2．45—12．67）。结论：NRS2002对于老年病科住院患者住院时间有较好的预测性，但其在老年病科住院患者中的适用性还有待于深入分析。

Screening and assessment of nutritional risk in patients hospitalized in geriatric wards

Objective：To analyze the application of Nutritional Risk Screening 2002 （NRS2002） and screening of nutritional risks in patients hospitalized in geriatric wards. Methods： Nutritional risk and hospital stay in 345 patients hospitalized in geriatric wards were evaluated using European NRS2002, Miniature Nutritional Assessment （MNA） and Subjective Global Assessment （SGA）. Results： Sensitivity and area under curve of receiver operation characteristic curve （AUC-ROCC） of NRS2002 was 84.7% and 0. 899, respectively. By using NRS2002 for assessment, higher probability of hospital stay for more than 10 days were found to be associated with patients at risk of developing malnutrition as compared with those without （OR = 6.43, 95% CI = 2.45- 12.67）. Conclusion： NRS2002 is indicative of hospital stay in patients hospitalized in geriatric wards, with the applicability to be further studied.
