Except for one study, all articles reported that the dietary intake was significantly lower among ICU admitted patients. Nutrition Risk in Critically Ill score, Acute Physiology and Chronic Health Evaluation (APACHE II), Nutritional Risk Screening-۲۰۰۲ (NRS), and Subjective Global Assessment (SGA) measurement tools were used to predict the rate of malnutrition among the patients. Recorded reports indicate low calorie and nutrient intake among patients during ICU stay.Implications for Practice: The analyzed hospitals have unsuitable and inadequate nutritional care services.
