Nutritional risk screening in hospitalized patients with respiratory disorders / 中华临床营养杂志

ABSTRACT

Objective To explore the nutrition risk,undemutrition rates,and nutrirlon support in the hos-pitalized patients with respiratory disorders.Methods Totally 100 hospitalized patients in department of respirato-ry medicine of our hospital from October to December 2008 were enrolled in this study.The nutrition risks were screened on the next day after admission and then two weeks later using Nutrition Risk Screening(NRS2002).Body mass index(BMI)lower than 18.5 ks/m2,serum albumin(sALB)lower than 35 g/L,or pre-ALB was lower than 20 g/L Wag regarded as undemutrition.Results Among all these 100 patients evaluated by NRS2002,59 patients were judged at the risk of malnutrition and 54 patients developed undemutrition two weekB later The nutrition risk and undernutuition rate among non-ambulatory patients were 87.7%and 82.9%,which were signifi-cantly higher than in ambulatory patients(32.2%and 30.5%)(P<0.001).The nutrition risk and undernutu-ition rate were also significantly higher in patients who stayed in the hospital for more than 2 weeks than those for less than 2 weeks(75.0% vs 9.4%and 66.2% vs 21.9%,respectively)(P<0.001).Twenty-two patients received nutritional support.The ratio of parenteral nutrition and enteral nutrition wag 1.21.Conclusions NRS2002 can be used in the nutrition assessment in hospitalized patients with respiratory disorders.Non-ambulato-ry and a hospital stay of more than 2 weeks increase the nutritional risk and undemutrition rate.Only a small per-centage of patients receive nutritional support.
