Introduction: Eating disorders are among the most common problems in patients suffering from multiple trauma admitted to the ICU. They have a considerable impact on the increase of mortality risk. The present study aimed to determine the relationship between the Nutrition Risk in Critically ill (NUTRIC) score and the complications and mortality up to 48 hours after the discharge of multiple trauma patients admitted to the ICU of Alzahra Hospital in Isfahan between 2018 and 2019.

Methodology: This study was descriptive-analytical research on 68 multiple trauma patients admitted to the ICU of Alzahra Hospital. The NUTRIC 2002 scores of the said patients were calculated by evaluating the parameters of age, APACHE II, SOFA Score, days in the hospital to ICU admission, and the number of comorbidities. Two different study groups were compared in terms of the said parameters, one composed of living and the other of deceased subjects.

Findings: The mean NUTRIC 2002 Score was 3.5±0.03 in all studied patients. Out of the said patients, 67.6% and 32.4% of them were exposed to a low-risk eating disorder and a high-risk eating disorder, respectively. The mean of NUTRIC Scores in living and deceased patients were 2.82±3 and 1.19±5.83, respectively; which indicated that the deceased subjects had a higher NUTRIC Score (p<0.001).

Conclusion: The 2002 NUTRIC Score was higher in the deceased subjects than in the living patients. Thus, this score seems to be a valuable and usable criterion for determining the eating disorder and the risk of mortality in multi-trauma patients admitted to the ICU.
