| dc.description.abstract | BACKGROUND: Malnutrition is a major concern for patients admitted to Intensive Care Units both globally and in developing countries, and is associated with poor clinical outcomes such as prolonged length of hospital stay, increased mortality, and complications. Quick and simple nutrition screening methods can help to direct nutrition therapy in the intensive care unit. Ethiopia currently lacks validated tools for conducting nutritional screening among critically ill patients. The need for a validated tool to assess malnutrition risk, and the potential benefits it offers among critically ill patients in Ethiopia are the driving forces behind this study. OBJECTIVE: This study aims to assess the validity and predictive performance of the nutritional risk screening 2002 tool – NRS 2002 among patients admitted to Intensive Care Units of tertiary hospitals in Addis Ababa, Ethiopia in 2024. METHOD: A facility-based prospective cohort study was conducted using a structured questionnaire in Intensive Care Units of two tertiary public hospitals in Addis Ababa, Ethiopia for admitted patients aged ≥18 years from March 12 to May 20. A total sample size of 126 was used for the study. The results from the Full Nutritional Assessment were considered the gold standard and the results from the Nutritional Risk Screening 2002 tool – NRS 2002 the test tool. Sensitivity, specificity, Negative and Positive predictive values, Receiver Operating Characteristic analysis, and multiple binary logistic regression have been computed. RESULT: A total of 122 patients, predominantly male (54.1%), were included. 27% of the study participants died and 22.1% developed complications in the ICU during the study period. The NRS tool was found to have a sensitivity and specificity of 95.8% and 68.4% respectively; and a Cronbach’s alpha value of 0.868. This malnutrition screening tool is a significant predictor of death; AOR = 2.206 (95% CI: 1.496, 3.251; p< 0.05), and complications; AOR = 1.874 (95% CI: 1.265, 2.776; p< 0.05) but not prolonged length of ICU stay; 1.17 (95% CI: 0.821, 1.668; p > 0.05). CONCLUSION: The NRS 2002 tool is a valid nutritional screening tool with high sensitivity. It is also a significant predictor of death and complications during their ICU stay. | |
