Isolated or Combined Use of NUTRIC Score and NRS-2002 to Predict Mortality in Patients Admitted to the Intensive Care Unit for Respiratory Failure.

Introduction: Malnutrition is a common dysfunction in critically ill patients admitted to intensive care unit (ICU), and the assessment of nutrition in the ICU poses a unique challenge for clinicians. The aim of our study is to investigate the performance of nutritional screening tools in predicting hospital, 28-day and 3-month mortality in critically ill patients admitted to the ICU due to respiratory failure (RF). In this report; we aimed to share the 1-month preliminary results of our study and the 28-day mortality data with you. Materials and Methods: To the first 1-month preliminary report of our prospective observational study; all adult patients (≥18 years old) who applied to the ICUs with RF and stayed in the ICU for more than 72 hours were included, with the decision of the ethics committee numbered 2012- KAEK-15/2627. Multiple logistic regression analysis and relative risk for mortality prediction performance of the instruments were used to test the complementarity between mNUTRIC and NRS-2002. Results: One hundred twenty patients were evaluated. The outcomes of the patients according to 1-month mortality are given in Table 1. In patients included in the study, 50% (p=0.453) by NRS-2002, 71.7% (p<0.001) by mNUTRIC, and 40.8% (p=0.046) by mNUTRIC + NRS-2002 (score ≥5) were found to be at high nutritional risk. The risk of 28-day mortality was 8.5 times higher in patients with mNUTRIC ≥5, one times in patients with NRS-2002 ≥5, and 1.5 times more in patients with mNUTRIC + NRS-2002 ≥5 (Table 2). mNUTRIC AUC 0.782; NRS-2002 AUC 0.521 and mNUTRIC + NRS-2002 AUC 0.636 were detected (Figure 1). Conclusion: There is no specific study in the literature on nutritional risk screening of critically ill patients with RF. It is not known whether the sensitivity of these scores changes according to the type of RF. The mNUTRIC score is statistically superior to the use of NRS-2002 and the combined two scores in predicting 28-day mortality in patients admitted to the ICU with RF. [ABSTRACT FROM AUTHOR]
