老年住院患者循证营养支持的安全性及有效性研究

Study on the Safety and Effectiveness of Evidence-based Nutrition Support for Elderly Inpatients

【目的】观察个体化的营养干预措施对具有营养风险老年患者的安全性及干预效果。【方法】对2011年9月至2012年3月在本院干部保健科新入院的129例老年患者（年龄≥65岁）采用营养风险筛查2002（nutrition risk screening 2002，NRS2002）标准进行营养风险筛查，以发现具有营养风险的患者，并对其进行个体化的营养干预。分别在营养干预前、干预两周后、1个月后检测患者肝肾功能、血脂、蛋白水平，比较营养干预前后营养状况。【结果】本研究结果显示，本组129例患者中N RS≥3分的患者有32例，营养风险发生率为24．8％（32/129）。营养干预两周后、1个月后患者肝肾功能、血脂指标无明显变化，血清总蛋白、白蛋白及血红蛋白水平明显升高，且与干预前相比较差异均有显著性（ P ＜0．05）。【结论】个体化的营养干预对具有营养风险的老年患者安全、有效。

[Objective] To observe the safety and effectiveness of individual nutritional intervention on eld-erly patients with nutritional risk .[Methods] Totally 129 elderly inpatients（age≥65 years old） in department of cadre care of our hospital from Sept .2011 to March 2012 were enrolled in the study .Nutritional risk screening 2002（NRS 2002） standard was performed to find the patients with nutritional risk .The patients with nutritional risk were given individual nutrition intervention .Liver and kidney function ,blood lipids and proteins before ,2 weeks and 1 month after nutrition intervention were examined .The nutrition status was compared between before and after intervention .[Results] The research results showed that NRS of 32 pa-tients in 120 patients were equal or over 3 points ,and the incidence of nutritional risk was 24 .8% （32/129） . The indicators such as liver and kidney function and blood lipids 2 weeks and 1 month after nutritional inter-vention had no change ,while serum levels of total protein ,albumin and hemoglobin were obviously increased , and there was significant difference between before and after intervention （ P〈0 .05） .[Conclusion]Individual nutritional intervention is safe and effective for elderly patients with nutrition risk .
