Sažetak
Malnutrition in vulnerable patient populations must be rapidly detected using techniques that are easy to incorporate into everyday clinical practice. The new recommendations defined the 7- point Subjective Global Assessment (SGA) as optimal for nutritional assessment in chronic kidney disease (CKD), while Geriatric Nutrition Risk Index (GNRI) demands additional examination in elderly. This study aimed to determine the accuracy of several concise tools used in the clinical practice and the correlation of this tools with functional method hand grip strength (HGS) in elderly patients with CKD. In this cross- sectional study, anthropometric and functional data for 50 elderly hemodialysis patients were analyzed using numerous survey-based tools for screening nutritional status (Malnutrition Screening Tool – MST, Nutritional Risk Screening 2002 - NRS2002, Malnutrition Universal Screening Tool - MUST, Mini Nutritional Assessment - MNA, GNRI), which we compared to the standard 7-point SGA nutritional assessment tool. The sensitivity, specificity, and accuracy of these tools for detecting malnutrition were compared with the standard by using receiver operating characteristic (ROC) curve analysis. 7-point SGA classified 36.6% of participants as well nourished, and 63.4% as mildly to moderately malnourished, while the simplest alternative methods showed lower accuracy, classifying much higher proportions of participants as well nourished (MST, 92.0% ; NRS2002, 80.4%). MNA had the highest accuracy based on receiver operating characteristic curves. HGS correlated moderately with 7-point SGA (r = 0.331), MNA (r = 0.410), and GNRI (r = 0.320). Our small study suggests that MNA is the best tool for malnutrition risk screening in elderly with CKD. Combining HGS with concise tools, such as GNRI, may provide better results and unburden healthcare professionals.
