营养支持对消化内科住院营养风险病人临床结局影响

THE EFFECT OF NUTRITIONAL SUPPORT ON CLINICAL OUTCOME IN DIGESTIVE PATIENTS AT NUTRITIONAL RISK

目的调查消化内科住院病人营养风险和营养不良发生率、实际应用营养支持情况及营养支持对临床结局的影响。方法以我院消化内科住院496例病人为研究对象,应用营养风险筛查(NRS 2002)进行筛查,记录其营养支持情况、感染性及非感染性并发症发生率。NRS 2002评分≥3分为存在营养风险,人体质量指数(BMI)<18.5kg/m2为存在营养不良。结果消化内科住院病人营养不良及营养风险发生率分别为6.7%、33.5%。存在营养风险病人营养支持率为42.8%,无营养风险病人营养支持率为15.8%。存在营养风险病人中,有营养支持组感染性并发症的发生率低于无营养支持组,差异有显著性(χ2=5.623,P<0.05);无营养风险病人中,有营养支持病人感染性并发症发生率高于无营养支持组,差异有显著性(χ2=5.786,P<0.05)。结论营养支持可以减少存在营养风险病人并发症的发生,存在营养风险的消化内科住院病人营养支持没有得到足够重视。

Objective To investigate the nutritional risk （NR）, prevalence of malnutrition, practical application of nutri- tional support （NS） and the effect of NS on the outcomes in patients with digestive diseases at NR. Methods The objects of the present research consisted of 496 patients hospitalized in the Department of Gastroenterology in our hospital. Using Nutritional Risk Screening （NRS 2002） to screen and record their NS, the incidences of infective and non-infective complications. NRS 2002≥ was classified as nutritional risk, and BMI 〈18.5 kg/m2 as malnutrition. Results The prevalences of malnutrition and NR in the patients surveyed were 6.7% and 33.5%. respectively. The NS rate in patients at NR was 42.8%, for those without NR, the NR was 15.8%. The prevalence of infective complications in patients at NR received NS was lower than that without, the difference was significant （X2 =5.623,P〈0.05）, of those without NR, the incidence of infective complications was higher in the NS group than without （X2=5.786,P〈0.05）. Conclusion Nutritional support may reduce complications in patients at nutritional risk, this issue has not been received sufficient attention to in in patients treated in the department of digestive system diseases.
