Abstract
Introduction: The aim of the present study was to investigate the relationship between the nutritional status of patients with different methods on the day of admission and dietary intake during the stay with the ICU mortality rate.
Methods: In this prospective cohort study, 125 patients were studied from admission to discharge in eight ICUs. At the time of admission, the nutritional status of the patients was assessed using the SGA questionnaire, anthropometric measurements, biochemical indices, body composition markers and the assessment of Organ Function Impairment (SOFA) and Severity of Illness (APPACHE) scores. The prescribed and received diet of the patients during their stay was recorded. By recording the mortality cases of this unit, the factors related to the mortality were also determined.
Results: Based on the SGA questionnaire, the rate of malnutrition on the day of admission was 28.8% and 29.6% of patients died during their stay in the intensive care unit. It was also found that a one-unit increase in serum IL-6 level and SOFA score at admission increased the risk of death during the stay in the ward by 1.008 and 1.14, respectively (P=0.003 and P=0.01), and with a one-gram increase in protein intake, the risk of death during the stay in the ward decreased by 8% (P<0.001).
Conclusions: This study showed that serum interleukin-6 level and SOFA score at the time of admission and the amount of protein intake during the stay in the ward affect the mortality rate in the ICU patients.
