Objective
Delayed enteral nutrition (EN), defined as EN started ≥ 48 hours after admission to the pediatric intensive care unit (PICU) is associated with an inability to achieve full EN and worse outcomes in critically ill children. We reviewed nutritional practices in 6 medical-surgical PICUs and determined risk factors associated with delayed EN in critically ill children.
Design
Retrospective cross-sectional study using medical records as source of data
Setting
Six medical-surgical PICUs in northeastern United States
Patients
Children < 21 years old admitted to the PICU for ≥ 72 hours excluding those awaiting or recovering from abdominal surgery.
Measurements/Main Results
A total of 444 children with a median age of 4.0 years were included in the study. EN was started at a median time of 20 hours after admission to the PICU. There was no significant difference in time to start EN among the PICUs. Of those included, 88 (19.8%) children had delayed EN. Risk factors associated with delayed EN were: non-invasive (odds ratio [OR]: 3.37; 95% CI: 1.69-6.72) and invasive positive pressure ventilation (OR: 2.06; 95% CI: 1.15-3.69), severity of illness, (OR for every 0.1 increase in Pediatric Index of Mortality 2 score: 1.39; 95% CI: 1.14-1.71) as well as procedures (OR 3.33; 95% CI: 1.67-6.64) and; gastrointestinal disturbances (OR: 2.05; 95% CI: 1.14-3.68) within 48 hours after admission to the PICU. Delayed EN was associated with failure to reach full EN while in the PICU (OR 4.09; 95% CI: 1.97-8.53). Nutrition consults were obtained in less than half of the cases and none of the PICUs employed tools to assure the adequacy of energy and protein nutrition.
Conclusions
Institutions in this study initiated EN for a high percentage of patients by 48 hours of admission. Non-invasive positive pressure ventilation was most strongly associated with delay EN. A better understanding of these risk factors and assessments of nutritional requirements should be explored in future prospective studies.
