Introduction: Adequate nutrition is necessary during critical illness and is closely linked with clinical outcomes. Therefore, determination of nutrition status in critically ill patients is necessary. So, this study evaluates the nutritional status and determine malnutrition markers in ICU patients receiving nutritional support in Isfahan, Iran.Methods: This cross sectional study was performed at AL-Zahra Hospital of Isfahan University of Medical Sciences, Iran. Nutritional screening including APACHE score, NUTRIC score and nutritional assessment including laboratory dates, weight, energy and protein balance was assessed. Moreover, Occurrence of gastro-intestinal problems was evaluated.Results: In total, 55(35 men and 20 women) patients met the inclusion criteria with median [IQR] age of 49[18-77] and median [IQR] weight of 75(55-100). Also, BMI determination showed that 11% of patients had inadequate body weight (BMI<18.5). During the inpatient period, nutrition screening showed that a median range of NUTRIC score was 3[2-5] and APACHE score was 23[18-27]. In addition, median range of weight decreased to 71 [50-96] kg. Also, median intake of energy and proteins for 7 days were 1840[750-2100] and 65 [25-94] respectively that seemed inadequate regarding target energy and protein requirement (1920[1200-2740] and 86[49-129] respectively). After gastro-intestinal assessment, 20% of subjects had nausea and vomiting, 10% obstipation, 5% diarrhea and 20% enteral feeding intolerance.Conclusions: Our results suggest that although nutritional adequacy is prevalent among ICU patients, but providing better evaluation about factors that effect on nutritional adequacy on hospital outcomes seems to be a necessary.
