Evidence-Based Investigation of Nurses' Nutrition Interventions in Intensive Care Patients Regarding Enteral Nutrition.

Abstract

The aim of this study was to examine the practices and knowledge levels of nurses regarding enteral nutrition interventions in intensive care unit patients in terms of evidence. This cross-sectional study was conducted in 2 hospitals between May and August 2021. A total of 136 nurses working in the intensive care units of the hospitals completed online questionnaires including demographic characteristics and questions about enteral nutrition. According to the nurses' knowledge level about the indication of enteral nutrition formulas, the following were incorrect or incomplete: their knowledge about transition to parenteral nutrition in case of nutritional contraindications, what to do when the amount of gastric residual volume in tolerance is >500 mL every 6 hours, the conditions for starting enteral nutrition, and which formulas are appropriate to use. Regarding their knowledge about enteral feeding tubes/sets, their knowledge about radiologic imaging after tube placement, measurement of gastric pH level, and marking the tube location was insufficient. Differently, the correct answer percentages of the nurses in 11 of the 13 questions regarding the principles of enteral nutrition practice were above 70%. Nurses had adequate knowledge of the principles of enteral nutrition practice, but their knowledge of the indication of enteral nutrition formulas and the evidence for enteral feeding tubes/sets varied. The results showed that nurses need to gain information about the indication of enteral nutrition formulas and evidence related to enteral feeding tubes/sets.
