Prevalence of nutritional risks, malnutrition and application of nutritional support rates at one Chongqing teaching hospital

Abstract

To prospectively explore the prevalence of nutritional risks and undernutrition, obesity and the application of nutritional support in First Affiliated Hospital of Chongqing Medical University and compare the data with those of big hospitals in Beijing. A total of 2255 inpatients from the department of gastroenterology, gastrointestinal surgery, neurology and respiratory medicine at our hospital were consecutively recruited from June to October 2011. Nutritional Risk Screening 2002 (NRS2002) was performed at 24 h post-admission. And nutritional support was examined during the period of hospitalization. Among them, 2166 patients (96.1%) received NRS2002. The overall prevalence of nutritional risk was 29.5% (638/2166), undernutrition 12.2% (265/2166) and the incidence of obesity 2.4% (52/2166). For the patients at nutritional risks, only 9.2% (59/638) of them received nutrition support. The nutrition support of gastrointestinal surgery department was higher than Beijing, and that of neurology department was lower than Beijing. For those not at nutritional risks, 1.0% (16/1528) received nutritional support. And that of 4 department were all lower than Beijing (all P < 0.01). The nutritional risk patients on nutritional support rates is lower at First Affiliated Hospital of Chongqing Medical University and excessive use of parenteral nutrition support seems routine. The Chinese Society for Parenteral and Enteral Nutrition (CSPEN) guidelines of rational nutrition support should be vigorously promoted.
