Nutritional risk and nutrition support in hospitalized patients in general surgery department in Shanghai / 中华临床营养杂志

ABSTRACT

ObjectiveTo determine the prevalence of nutritional risk and application of nutrition support in hospitalized patients in the department of general surgey,and to evaluate the relationship between nutrition support and clinical outcome as well as between nutritional risk and clinical outcome.MethodsHospitalized patients in the department of general surgery were enrolled from September 2009 to April 2010.The patients were screened using Nutritional Risk Screening 2002 ( NRS 2002) on admission.Data were collected on the application of nutrition support within 2 weeks,complication rate,length of stay,and hospital charges.ResultsAltogether 3000 patients were included in the present study.The overall prevalence of nutritional risk was 18.5％,in which gastric cancer patients showed the highest prevalence (48.3％ ).The proportion of patients receiving nutrition support was 44.1％ in those with nutritional risk and 14.3％ in those without nutritional risk.The ratio of parenteral nutrition to enteral nutrition was 1.21.The patients with nutritional risk had higher complication rate,longer length of stay,and higher hospital charge [24.1％ vs.14.2％,(11.1 ±4.8) daysvs.(9.6±3.7) days,(12891.5±4831.2) yuan vs.(9982.7 ±3996.4) yuan,all P=0.0000].Among the gastric cancer,colorectal cancer,and hepato-biliopancreatic cancer patients with nutritional risk,the complication rate,length of stay,and hospital charge were significantly lower in the patients receiving nutrition support than those in the patients receiving no nutrition support ( all P ＜ 0.05 ).ConclusionsA number of inpatients in general surgery department are at nutritional risk.The prevalence of nutritional risk is considerably high in gastric cancer patients.Nutritional risk is correlated with the clinical outcome of the patients.Nutrition support may improve the clinical outcome of gastric cancer,colorectal cancer,and hepato-bilio-pancreatic cancer patients.
