摘要

目的 应用营养风险筛查2002(nutrition risk screening,NRS 2002)调查老年科住院患者的营养风险、营养不足发生率及营养支持的现状.方法 选择 2010年1月至2010年6月在长宁区中心医院老年科住院的患者120例,65-89岁,平均年龄(72±6.3)岁.,应用NRS 2002方法对患者入院后第2天和出院时进行营养风险筛查,并调查患者的营养支持状况.NRS 2002≥3分有营养风险,体质指数(BMI)<18.5kg/m2并结合临床状况判定营养不足.结果 人院时所有患者营养风险发生率为26.6%,所有患者的营养支持率为35.0%,肠外与肠内营养比例为2:7.结论 NRS 2002适用于老年住院患者的营养风险筛查.营养支持在老年患者中不够合理和充分.%Objective To investigate the nutritional risk, incidence of malnutrition and nutritional support status in the elderly inpatients by applying Nutrition Risk Screening 2002 ( NRS 2002) Methods 120 cases (≥65 years old) hospitalized in Changning District Central Hospital from January 2010 to June 2010 were consecutively enrolled in the study . NRS 2002 was applied to screen nutritional risk and investigate patients' nutrition status on the second morning after admission and at the time of discharge. The nutritional risk was determined by the assessed scores (≥ 3). Insufficient nutrition can be diagnosed with body mass index (BMI)( ＜18.5 kg/m2 ) combined with clinical status of nutrition. Results The rate of nutritional risk was 26.6 ％ on the evaluated morning after admission. Nutritional support index of all patients was 35.0 ％ .The ratio of parenteral nutrition and enteral nutrition was 2 ∶ 7. Conclusions It is suitable to use NRS 2002 to screen the nutritional risk in elderly patients . The application of nutritional support in the elderly is neither reasonable nor full enough.
