Abstract

Introduction: In critically ill patients, nutritional risk and hyperglycemia are associated with an increased incidence of unfavorable outcomes. Objective: To evaluate the relationship of nutritional risk by the Nutrition Risk in Critically III, modified version (mNUTRIC) and glycemic profile in the outcomes of discharge, death and length of stay in critically ill patients and to verify the impact of the Acute Physiology and Chronic Health Disease Classification System II (APACHE II) and the Sepsis-Related Organ Failure Assessment (SOFA) tools on these outcomes. Method: Prospective longitudinal study developed in an intensive care unit (ICU). Adults were included, with ≥ 48 hours of hospitalization and with a minimum record of two blood glucose measurements. Patients in palliative care, readmitted to ICU and pregnant women were excluded. Fisher's Exact test and Shapiro Wilk test were used to evaluate categorical and continuous variables, respectively. Subsequently, the Mann-Whitney or unpaired t-Student test was used. Logistic and linear regression analysis was performed. The significance level adopted was 5%. Results: When evaluating 35 patients, 45.7% were at high nutritional risk. An association was observed between nutritional risk and discharge and death outcomes; SOFA was associated with death and length of hospital stay. The increment of 1 point in the SOFA score increased the chance of death by 83% and a longer hospital stay by 0.49 days. Glycemic profile and APACHE II were not associated with outcomes. Conclusion: the SOFA score was the instrument that showed significant associations with the outcome of death and longer hospital stay in critically ill patients.
