Abstract
Introduction and Objectives: Since malnutrition is so common among hospitalized patients, especially those in intensive care units (ICUs), it is of utmost significance to provide these patients with adequate nutritional support. The present study aimed to investigate the status and nutritional support of ICU patients in Iran.
Methods and Materials: In this systematic review, according to recommendations from the Cochrane Handbook, a query was conducted on Medline, Web of Sciences, PubMed, Scopus, and SID databases for articles submitted on nutritional support for ICU patients hospitalized in Iran until April 9, 2023, using the keywords of "intensive care unit" OR "ICU" AND "nutritional support" and "Iran."
Results: Finally, 20 original articles, cross-sectional, prospective cohort, and retrospective conducted on human samples, were entered in this study. Except for one study, all articles reported that the dietary intake was significantly lower among patients admitted to the ICU. Researchers used the Nutrition Risk in Critically Ill (NUTRIC) score, Acute Physiology and Chronic Health Evaluation (APACHE II), Nutritional Risk Screening-2002 (NRS), and Subjective Global Assessment (SGA) measurement tools to predict the rate of malnutrition among patients. Recorded reports indicate low calorie and nutrient intake among patients during their ICU stay.
Conclusion: The hospitals analyzed here have unsuitable and inadequate nutritional care services. In addition, the patient's intake of calories, protein, and other daily nutrients was significantly lower than their consumption. This amount is not satisfactory and leads to a cascade of undesirable outcomes for patients.
