Introduction: Critical patients presenting a higher risk of malnutrition and nutritional support may favorably affect the severity of the disease. Thus, early identification of patients who are at nutritional risk and more likely to benefit from nutritional therapy is extremely important.

Objectives: To evaluate the nutritional risk of critically ill patients admitted to the Intensive Care Unit of a university hospital using the NUTRIC Score tool.

Methods: An observational and retrospective study was performed with critically ill patients over 18 years of age admitted from March to August 2018. Data were collected from patients’ electronic files and in control sheets. The statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) software version 23. Results: 82 critical patients participated in the study, most of them male (52.4%), with a mean age of 63, 1 ± 16.1 years. The main diagnoses leading to Intensive Care Unit admission were pre- and postoperative (40.2%). The use of mechanical ventilation was observed in 31.7% of patients and the main clinical outcome was high for the ward (76.8%). Most of the patients (43.9%) were classified as having nutritional risk by NUTRIC. When associating the presence or not of nutritional risk with the variables, a significant difference was observed between length of stay in the Intensive Care Unit (p>0,004), prognostic scores APACHE and SOFA (p>0,000), use of mechanical ventilation (p>0,002) and clinical outcome of the patient (p>0,014).

Discussion: Studies show the significant association between patients with high NUTRIC risk and longer Intensive Care Unit stay, besides the use of mechanical ventilation and higher mortality rates.

Conclusion: NUTRIC Score identified a nutritional risk in more than 40% of critically ill patients, which reinforces the relevance of nutritional care and the identification of early nutritional risk in the intensive care setting.
