The Nutrition Risk in Critically Ill score (NUTRIC) is an important nutritional risk assessment instrument for patients in the intensive care unit (ICU). The purpose of this study was to evaluate the power of the score to predict mortality in patients treated for sepsis and to forecast increased resource utilization and nursing workload in the ICU. The NUTRIC score predicted mortality (AUC 0.833, p < 0.001) with the optimal cut-off value of 6 points. Among patients with a score ≥ 6 on ICU admission, the 28-day mortality was 61%, and 10% with a score < 6 (p < 0.001). In addition, a NUTRIC score of ≥6 was associated with a more intense use of ICU resources, as evidenced by a higher proportion of patients requiring vasopressor infusion (98 vs. 82%), mechanical ventilation (99 vs. 87%), renal replacement therapy (54 vs. 26%), steroids (68 vs. 31%), and blood products (60 vs. 43%); the nursing workload was also significantly higher in this group. In conclusion, the NUTRIC score obtained at admission to the ICU provided a good discriminative value for mortality and makes it possible to identify patients who will ultimately require intense use of ICU resources and an associated increase in the nursing workload during treatment.

Background: The mNUTRIC score is a nutrition risk assessment tool. The aim of this study was to evaluate mNUTRIC score ability to predict 28-mortality, icu resource utilization and nursing workload for patients with sepsis and septic shock. Methods: We performed a secondary analysis of prospectively collected data from a ICU sepsis registry database. The study included adults diagnosed with sepsis or septic shock, admitted from January to December 2014.Results: The study included 146 patients. In the ROC curve analysis the mNUTRIC score had the ability to predict 28-day mortality with an AUC of 0.833 (95% CI 0.76-0.89). Additionally group of patients with NUTRIC score ≥ 6 points more frequently required vasopressor infusion, mechanical ventilation, renal replacement therapy, thromboprophylaxis and blood products use. Nursing workload was also significantly higher in this group (TISS-28: 36 pts., IQR 33 – 40 vs. 31 pts, IQR 28 – 34, p<0.001).Conclusion: The mNUTRIC score obtained at admission to the ICU provided a good discriminative value for 28-mortality and makes it possible to identify patients who will ultimately require intense use of ICU resources with an associated increase in the nursing workload during ICU sepsis treatment.
