Abstract
Aim: The assessment of the nutritional status of hospitalized patients is important to detect individuals who are under malnourishment risk and malnutrition-related conditions. The present study aimed to screen the nutritional status of hospitalized patients with Nutritional Risk Screening 2002 (NRS-2002) and Subjective Global Assessment (SGA) screening and to compare the results of two screening methods in predicting malnutrition. Materials and Methods: NRS-2002 and SGA were administered to 134 non-critical service patients within the first days of hospital admission. Tool performance in predicting malnutrition and the association with length of hospital stay (LOS) were analyzed. Results: 22.4% (n=30) of the patients were at nutritional risk when screened with NRS-2002; when screened with SGA, 35.8% (n=48) of the patients were found to be malnourished (p=0.015). The hospital LOS (day) of malnourished patients and non-malnourished patients according to NRS-2002 were similar. However, according to SGA screening, the hospital LOS of malnourished patients was longer than non-malnourished patients (17.90±16.93 vs 10.79±11.23) (p=0.004). In both screening tools most of the malnourished patients were overweight or obese (the total overweight and obese patients rate 70% and 75% according to NRS-2002 and SGA; respectively). Factors associated with malnutrition were only age and hospital LOS (p<0.05). Conclusion: Considering current criteria for nutritional risk, NRS-2002, as an objective and remarkably powerful tool, seems to provide a better yield for an objective assessment. Besides this, adding subjective parameters to the assessment by applying SGA could increase the capability of detecting the nutrition risk of hospitalized patients for a comprehensive nutritional assessment.
