Dietitian's approach to managing enteral nutrition intolerance when a formula change is indicated: A clinical practice survey

Abstract

Background: Enteral nutrition intolerance (ENI) is often defined as one or more gastrointestinal (GI) symptoms related to enteral nutrition (EN) and may have significant impact on patient outcomes. There are multiple strategies to help manage ENI, such as changing the EN formula. The objective of this practice survey was to understand prevalence of ENI, management of ENI symptoms, and EN formula features considered when changing formulas to manage ENI. Methods: Canadian clinical dietitians working across care settings (n = 4827) were invited to complete a 28‐question online survey if involved in the management of adult and/or pediatric patients receiving EN. Results: Five hundred seventeen surveys were analyzed. Significantly more dietitians in adult vs pediatric settings (83.4% and 59.1%, respectively; P = 0.0012), reported ENI in <40% of patients. Assessing medications, elevating the head of the bed, and changing EN infusion rate, volume, or feeding regimen were the highest‐ranked strategies to manage ENI symptoms. Most (>90%) respondents change the EN formula <50% of the time to manage ENI. Dietitians consider caloric density and protein form as the most important EN features to manage upper‐GI symptoms vs fiber source, osmolality, and form of protein to manage lower‐GI symptoms. EN with real‐food ingredients was ranked higher in importance for managing upper‐ and lower‐GI symptoms by dietitians in pediatric vs adult settings. Conclusion: To manage ENI symptoms, dietitians consider multiple strategies before deciding to change the EN formula. When a formula change is indicated, dietitians consider different EN features for the management of upper‐ and lower‐GI symptoms.
