ABSTRACT
Objective:To investigate the nutritional risk and prevalence of malnutrition in patients with terminal stage gastrointestinal malignant tumors in a tertiary hospital in Changsha.Methods:Cluster sampling was used to conduct a cross-sectional survey of inpatients from Departments of Gastroenterology, Gastrointestinal Surgery, Hepatobiliary Surgery and Oncology in Hunan Provincial People's Hospital from January 2019 to July 2020. Nutritional Risk Screening 2002 (NRS 2002) was used to assess the prevalence of nutritional risk with malnutrition defined as concurrent presence of BMI < 18.5 kg/m 2, poor general condition and NRS 2002 nutritional impairment score of 3. Step 2 of Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria (without whole body muscle mass) was adopted to diagnose malnutrition. Step 3 of GLIM criteria was used to evaluate the prevalence of severe malnutrition. Results:A total of 802 patients registered in the 4 departments were selected for screening via cluster sampling and 514 were enrolled according to the inclusion/exclusion criteria. The prevalence of nutritional risk in patients with terminal stage gastrointestinal cancer was 49.8% (256/514). The prevalence of malnutrition and severe malnutrition per GLIM criteria were 41.6% (214/514) and 18.3% (94/514), respectively.Conclusions:Although nutritional support therapy is not recommended for patients with end-stage cancer. This paper suggests that the prevalence of nutritional risk and malnutrition in patients with end-stage gastrointestinal cancer is not as high as described in some articles.
ABSTRACT
Nutritional support therapy includes three main components:nutritional screening,nutritional assessment,and nutritional intervention.It is important to emphasize that nutritional screening and nutritional assessment are two different concepts and definitions,which are often confusing for many physicians,nurses,and dietitians.In this review,we present an overview on the main concepts about nutritional screening and nutritional assessment,highlight their features and complementarity,and discuss the future perspectives in the clinical practice.
