Characteristics of enteral and oral nutrition support among infants and young children in the pediatric intensive care unit: A descriptive cohort study.

Background: Children who are critically ill are often reliant on enteral and oral nutrition support. However, there is limited evidence to guide "what" to prescribe, and current practice is unknown. The primary objective of this study was to describe enteral nutrition prescription in children ≤2 years of age in the pediatric intensive care unit (PICU). The secondary objectives were to describe oral nutrition support practices and factors associated with the use of increased energy and protein density nutrition support.

Methods: Children ≤2 years of age admitted to participating PICUs over a 2-week period in June 2021 were enrolled. Data were collected on PICU admission days 1 to 7, 14, 21, and 28 on the mode of nutrition, enteral and oral nutrition support prescription, and dietitian intervention.

Results: Eighty-four children were included (49 [58%] male; 79 [94%] ≤1 year of age). Enteral nutrition was administered to 79 (94%) children (with expressed breast milk in 45 [57%]). Forty-three children received formula as enteral nutrition. Increased energy and protein density formulas were provided to 14 (33%) children enterally, with concentrated standard infant formula powder being the most common (5 [12%]). Among children offered oral intake (22; 26%), three (14%) received oral nutrition support. Children who received increased energy and protein density enteral nutrition were more likely to receive dietitian intervention (P = 0.002).

Conclusion: In children ≤2 years of age admitted to PICU, expressed breast milk was provided to half of those requiring enteral nutrition and oral nutrition support prescription was infrequent. One third of children receiving formula via enteral nutrition received an increased energy and protein density feed, and this was strongly associated with dietitian intervention.
