Relationship between butritional scores and 28-day mortality in critical patients who received mechanical ventilator support for non-surgical reasons

Abstract

Aims: Malnutrition may cause an increase in morbidity and mortality in intensive care patients. In this study, we aimed to investigate the relationship between nutritional scores and 28-day mortality in critically ill patients followed on a mechanical ventilator for non-surgical reasons. Methods: 91 patients admitted to the intensive care unit for non-surgical reasons, followed up on mechanical ventilators, and whose data were available were included. The prognostic nutrition index (PNI), geriatric nutrition risk index (GNRI), nutritional risk index (NRI), and controlling nutritional status (CONUT) score were calculated from the data of the patients. Patients were divided into two groups survival and non-survival. Results: NRI, PNI, and GNRI scores were statistically significantly higher in the Survivor group. Neutrophil lymphocyte ratio, LDH albumin ratio, CONUT, APACHE, and SAPS scores were statistically higher in the nonsurvivor group. In logistic regression analysis for nutritional scores, CONUT was found to be an independent risk factor for mortality (table 5). In the ROC analysis, the AUC value for CONUT was 0.925. The cut-off value for CONUT was 7.5, the sensitivity was 86.4%, and the specificity was 87.0%. Conclusion: The CONUT nutrition score, which can be easily calculated from routine parameters and does not cause extra costs, can be used as an independent evaluation tool in determining the 28-day mortality of intensive care patients.
