Introduction: Undernutrition of patients is one of the most important and effective issues in response to treatment and mortality rate. The prevalence of undernutrition in hospitalized patients is 22 to 50%. Little attention has been paid to this issue due to lack of a proper nutritional screening system. Nutrition of the patients admitted to ICU and maintaining their homeostasis requires proper and scientific management. Early nutritional support reduces the severity of disease, complications, and length of hospital stay in the intensive care unit. The aim of present study was to use the Nutritional Screening System (NRS 2002) in multiple trauma patients admitted to ICU.

Methods: The present study was conducted on 100 multiple trauma patients admitted to the ICU of Al-Zahra Hospital in Isfahan in 2018. The required information form was completed for each patient. In this nutritional system, the severity of disease and level of undernutrition of patients are divided into three categories: mild, moderate and severe. In the NRS 2002 system, the final score varies from 0 to 7. The nutrition care program starts with a final score of ≥ 3.

Results: In the present study, the results showed that weight loss in the last three months was 32%, and the level of nutrients received during the last week was 30%. Also, 42% of patients were severely ill and 45% needed nutritional support. Also, 68% of patients did not have undernutrition problems. Based on the independent t-test, weight loss during the last three months, reduction of calorie intake and severity of previous disease were effective in the type of treatment.

Conclusion: The NRS 2002 method is very valuable and reliable due to the rapid and easy identification of undernutrition patients based on items that are readily available and its applicability if the reporter is not a nutritionist.
