老年肝胆外科住院患者的动态营养风险筛查

目的调查老年肝胆外科住院患者营养风险、营养不足发生率以及营养支持应用状况。方法采用定点连续抽样，对156例老年肝胆外科住院患者（≥65岁）人院后第2天早晨和住院2周或出院时进行营养风险筛查2002（NRS 2002）的动态描述性研究。结果NRS 2002的适用率为96．8％（151／156）。患者总的营养风险发生率为36．9％（57／156），营养不足发生率为26．2％（41／156）。住院时间大于2周的患者营养风险和营养不足发生率分别为49．6％和36．7％，住院时间小于2周的患者营养风险和营养不足发生率分别为37．3％和21．4％，两者相比差异具有统计学意义（P〈0．05）。存在营养风险和无营养风险患者营养支持率分别为64．1％和17．4％。其中，接受大手术患者中有营养风险和无营养风险患者的营养支持率分别为87．9％和36．8％，接受中、小手术患者中有营养风险和无营养风险患者的营养支持率分别为41．3％和9．6％。结论NRS 2002适用于老年肝胆外科住院患者的营养风险筛查。住院时间大于2周老年肝胆外科住院患者营养风险和营养不足发生率反而有所增加。临床营养支持在肝胆外科需要更加重视住院患者的营养问题，临床上存在肠外、肠内营养的不合理应用。

Nutritional risk screening in elderly inpatients with hepatobiliary diseases

Objective To investigate the nutritional risk,malnutrition rate,and nutritional support in elderly inpafients with hepatobiliary diseases.Methods Totally 156 eldedy inpatients(≥65 years)with hepatobiliary diseases were consecutively enrolled.Nutritional Risk Screening 2002(NRS 2002)was applied to screen nutritional risks on the next morning after admission and two weeks after admission or on the discharge day.Results Of 156 enrolled patients,151 patients(96.8%)completed the NRS 2002 screening.The nutrition risk and malnutrition rate were 36.9%(57/156)and 26.2%(41/156),respectively.The nutrition risk and malnutrition rate were significantly higher in patients with a hospital stay longer than 2 weeks than those with a hospital stay less than 2 weeks(49.6%and 36.7% vs.37.3%and 21.4%,respectively)(both P<0.05).In addition,100 patients(64.1%)with nutrition risk received nutrition support and 27 patients(17.3%)without nutrition risk received nutrition support.Among patients who had undergone major abdominal surgeries,137 patients(87.9%)with nutrition risk received nutrition support while 57 patients(36.8%)without nutrition risk received nutrition support.Conclusions NRS 2002 is a feasible nutritional risk screening tool for elderly inpatients with hepatobiliary diseases.A hospital stay more than 2 weeks the morbidity of the nutritional risk and malnutrition rate increased.Seems the value of nutritional support has not been well recognized in the department of hepatobiliary surgery,inappropriate application of nutritional support still exists.
