Prevalence, Risk Factors and Impact of Nutrition Interruptions in Critically Ill Children

Background: Enteral nutrition interruptions (ENI) are prevalent in the pediatric intensive care unit (PICU), but there is little evidence of their characteristics. Methods: This is a cross-sectional multicenter study including critically ill children on enteral nutrition. ENIs were classified as PICU procedures, procedures performed outside the PICU (PPOP), feeding intolerance and other criteria. The number and features of ENIs were collected. Results: A total of 75 children were enrolled. There were 41 interruptions affecting 37.3% of the patients with a median duration of 5 ± 9.4 h. The most common reason for ENI was PPOP (41.5%), followed by other criteria. Interruptions were considered preventable in 24.4% of the cases, but only eight were compensated. ENIs were more prevalent among children with cardiac disease (p = 0.047), higher PRISM (p = 0.047) and longer PICU stay (p = 0.035). There was association between PRISM and total interruption time (p = 0.02) and lower caloric intake (p = 0.035). Patients with respiratory illness (p = 0.022) and on noninvasive ventilation (p = 0,028) had fewer ENIs. ENI total time was associated with lower caloric (p = 0.001) and protein (p = 0.02) intake. Conclusions: ENIs are prevalent in PICU, especially in children with higher PRISM, longer PICU stays and cardiac disease, and result in lower caloric and protein intake.
