Abstract: Purpose: We evaluated the efficacy of the modified Nutrition Risk in Critically Ill (mNUTRIC) score for malnutrition screening and its association with mortality in intensive care unit (ICU) patients with COVID-19.Methods: The nutritional status of 129 COVID-19 ICU patients admitted between February 2021 and May 2022 was assessed using American Society for Parenteral and Enteral Nutrition/Academy of Nutrition and Dietetics (ASPEN/AND) criteria. The sensitivity, specificity, and clinical correlations of the mNUTRIC score were analyzed.Results: Of the 129 patients, 35 (27.1%) met the ASPEN/AND malnutrition criteria. Multivariable analysis identified the mNUTRIC score, underlying malignancy, and mechanical ventilation as significant factors associated with malnutrition. The mNUTRIC score had a sensitivity of 77.1% and specificity of 63.8% (area under the curve [AUC], 0.71; 95% confidence interval [CI], 0.62–0.79) for diagnosing malnutrition, improving to 88.6% and 80.9%, respectively, after adjusting for malignancy and ventilation (AUC, 0.89; 95% CI, 0.82–0.95). Patients with a low mNUTRIC score had a mortality rate of 2.9% and a median ICU stay of 7.7 days (range, 0–84.2 days), whereas those with a high score (≥5) had a mortality rate of 13.1% and a median ICU stay of 10.2 days (range, 1.4–88.5 days) (P=0.046 and P=0.011, respectively).Conclusion: The mNUTRIC score is an effective screening tool for malnutrition in ICU patients with COVID-19, especially those with malignancy or requiring mechanical ventilation, and is strongly associated with mortality and length of ICU stay.
