Background Nutritional status of patients with COVID‐19 can affect the recovery process of patients; however, no nutritional scale was introduced to evaluate the nutritional status of the patients. Thus, the main objective of this study was to examine the usefulness of Nutritional status‐2002 (NRS‐2002) among COVID‐19 patients admitted to the intensive care unit (ICU). Material and Methods In this cross‐sectional study, 73 patients with definitive corona diagnosis admitted to the ICUs of Al‐Zahra hospital, Isfahan, Iran in October 2020 to January 2021 were recruited. Dietary intake, NRS‐2002, demographic, anthropometric and biochemical indices of patients were recorded. Results The majority of patients were at risk for moderate (69.9%) to severe (12.3%) malnutrition. Daily calorie intake ( P = .001) and albumin ( P = .001) levels in deceased patients were significantly lower than the recovered group. A direct correlation between NRS‐2002 and age ( P < .001) and an inverse correlation with daily calorie intake ( P = .002), albumin ( P = .05) and PaO2 ( P = .034) was found. Moreover, there is a strong correlation between NRS‐2002 score and chance of death among COVID‐19 patients (OR=34.5, 95%CI:(5.2 ‐ 228.93), P‐value<0.001). Likewise, the levels of bilirubin direct (OR=8, 95%CI:(1.30 ‐ 49.38), P‐value=0.025) and creatine‐phosphokinase (OR=0.9, 95%CI:(0.99 ‐ 1.00), P‐value=0.035) have a significant direct association with chance of death. Conclusion Results showed patients with COVID‐19 admitted to the ICU did not have appropriate nutritional status and mortality was higher among patients with lower amounts of the serum albumin and daily calorie intakes. Furthermore, there is a strong association between the NRS‐2002 index and the chance of mortality in these patients.
