Relationship between mNUTRIC score and 28-day mortality in critical patients

Abstract

Aim: In this study, we aimed to investigate the effect of the modified NUTRIC score on 28-day mortality in critical patients in the internal medicine intensive care unit. Material and Methods: A retrospective review of patients in the intensive care unit between 01.10.2019 and 01.03.2020 was carried out. The study included patients aged >18 years, treated for more than twenty-four hours in the Intensive Care Unit, with mechanical ventilation for more than 48 hours. Patient demographic data, length of stay in the internal medicine intensive care unit, and the modified NUTRIC score were recorded. Patients were separated into two groups according to the calorie sufficiency calculated in the first 5 days as those receiving <70% energy or >70% energy. Results: One hundred twenty-eight patients were examined. Supportive treatment of vasopressor drugs was applied to 34 (26.6%) patients, renal replacement therapy to 35 (27.3%) and mechanical ventilation to 71.8% of the patients. The 28-day survival rate was determined to be statistically significantly low in the group with a high mNUTRIC score (p:0.044). The time spent on mechanical ventilation was determined to be statistically significantly longer in the group receiving >70% energy (p<0.05). Discussion: The higher rate of 28-day mortality in patients in the medicine intensive care unit was determined to be related to the higher mNUTRIC score. When >70% of the daily calorie requirement was administered to patients on a mechanical ventilator, the number of days spent on mechanical ventilation was high.
