OBJECTIVE: This retrospective observational study aims to evaluate the prognostic accuracy of Modified Nutrition Risk in Critically ill (mNUTRIC) compared to Nutrition Risk Score-2002 (NRS-2002) in patients hospitalized in the intensive care unit due to severe pneumonia during the pandemic period. METHODS: RT-PCR test and Chest CT was performed in all patients in the emergency department pandemic area. The CURB-65 at the time of admission to the emergency department and Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential organ failure assessment score (SOFA), NRS-2002 and mNUTRIC scores 24 h after hospitalization in the intensive care unit were calculated. The analysis of the data was made in IBM SPSS Statistics Base 22.0 package program. RESULTS: One hundred and twenty-five patients found to have severe pneumonia based on the chest CT taken in the emergency department pandemic area and hospitalized in the intensive care unit were included in the study. A real-time reverse transcription PCR (RT-PCR) test was positive in 30.4% (n: 38) of the patients. Additional nutrition treatment was initiated in 54.4% of the patients. In the analytical evaluation to predict nutritional treatment needs, mNUTRIC's AUC value (AUC: 0.681, 95% 0.582–0.780, p < 0.001) was higher than NRS-2002. While 64.8% (n: 81) of the patients were discharged, 35.2% (n: 44) died. In the analytical evaluation to predict mortality, the AUC value of mNUTRIC had the highest value (AUC: 0.875, 95% CI 0.814–0.935, p < 0.001). CONCLUSION: The mNUTRIC score can predict at an early period the nutritional needs and mortality of patients with severe pneumonia during the Covid-19 pandemic.
