Abstract:
Objective To analyze the risk of malnutrition in elderly hospitalized patients with infectious diseases by adopting four different nutritional screening tools, and to evaluate the efficiency of these screening tools. Methods A retrospective analysis was conducted on 300 elderly hospitalized patients admitted to a tertiary hospital in Sichuan Province. Four commonly used nutritional assessment tools in clinical practice such as Nutritional Risk Screening 2002 (NRS-2002), Subjective Nutrition Assessment (SGA), Micronutrition Assessment (MNA-SF), and Prognostic Nutrition Index (PNI) were adopted to evaluate the nutritional status of all patients. Using the consensus on malnutrition assessment (diagnosis) GLIM criteria as the gold standard, the diagnostic efficiency of NRS2002, SGA, MNA-SF, and PNI in diagnosing malnutrition in these elderly hospitalized patients with infectious diseases was compared. The Kappa coefficient was used to analyze the consistency between four objective nutritional screening tools and the GLIM gold standard. Results Among the 300 patients, 122 cases (40.67%) had malnutrition. The incidence rates of malnutrition risk evaluated by NRS2002, SGA, MNA-SF, and PNI were 56% (168), 60.33% (181), 59.33% (255), and 86.33% (259), respectively. The area under curve (AUC) of NRS-2002 in evaluating malnutrition was 0.877, and the AUCs of SGA, MNA-SF, and PNI were 0.668, 0.336, and 0.354, respectively. NRS-2002-based malnutrition risk assessment tool showed better sensitivity (70.22%), specificity (94.26%), PPV (68.45%), NPV (94.69), and consistency (Kappa=0.609) with malnutrition as defined in GLIM compared to the other assessment tools. Conclusion Compared with SGA, MNA-SF and PNI scores, NRS-2002, as an objective nutritional screening tool, demonstrates better diagnostic efficiency on identifying malnutrition in elderly hospitalized patients with infectious diseases.
