HN-01750129_Nutritional Risk Assessment in Critically Ill Patients

Introduction: Malnutrition is common in hospitalized patients specifically in critical illness and is associated with adverse clinical outcome such as prolonged length of ICU stays, decreased ventilator free days, increased morbidity and mortality. Therefore, early identification of malnutrition in these group, leads to improve clinical outcomes. This prospective observational study was conducted to identify nutritional risk in ICU patients using modified Nutric score that is the first nutritional risk assessment tool in critically ill patients.Methods: About 46 critically ill patients enrolled within 24 hours from their admission from three ICUs of 3 tertiary Hospitals in Tehran. A nurse, a nutritionist and an intensivist obtained data from patient’s medical records and calculated Nutric score. Demographic (age, sex), anthropometric data (MAC) and clinical outcome (mechanical ventilation days, enteral and parenteral days, length of ICU stay and mortality) was collected. Data analysis using SPSS version 25 software and the significance level of the test of 0.05 = α was considered.Results: The mean age of patients was 57.7±18.7 years and 29(%63) patients were male. The prevalence of malnutrition in 3 hospitals was 43.8, 33.3 and 53.3, respectively. In general, % 43.5 of patients were at high nutritional risk. Patients with Nutric score ≥5 had longer mean ICU average length of stay (4.5 versus 2.6) and mortality (%70 versus %15.4) (P<0.05). High mNUTRIC score (≥5) predicted mortality with area under the curve of 0.82 (95% confidence interval 0.68–0.93).Conclusion: Based on the findings, about 43.5% patients in ICUs have high nutritional risk with Nutric Score and was associated with increased ICU length of stay, mechanical ventilations and higher mortality.
