Abstract

The purpose was to compare, in elderly hospitalized patients, the performance of widely used nutritional screening and assessment tools and anthropometric parameters with the Nutritional Risk Screening (NRS-2002); and to evaluate their independent association with length of hospital stay. Nutritional-status screening and assessment was carried out using NRS-2002, Mini Nutritional Assessment (MNA), Subjective Global Assessment (SGA), Malnutrition Screening Tool (MST), and anthropometry. Patients classified by NRS-2002 as undernourished had an independent higher risk of longer length-of-stay (> 8 days): Odds ratio = 2.25 (95% Confidence Interval = 1.03 to 4.88). Nutritional "risk" by NRS-2002 is an independent risk factor for a long length of stay in elderly hospitalized patients, an important outcome predictor in this population.

摘要

目的是在老年住院患者中，比较广泛使用的营养筛查与评估工具及人体测量参数与营养风险筛查（NRS - 2002）的性能；并评估它们与住院时间的独立关联。使用NRS - 2002、微型营养评定法（MNA）、主观全面评定法（SGA）、营养不良筛查工具（MST）及人体测量法进行营养状况筛查与评估。被NRS - 2002分类为营养不良的患者有独立的更高风险出现更长住院时间（> 8天）：比值比 = 2.25（95%置信区间 = 1.03至4.88）。NRS - 2002所定义的营养“风险”是老年住院患者住院时间延长的独立风险因素，是该人群重要的预后预测指标。
