Abstract Background Optimal nutrition in children with severe bronchiolitis remains poorly described. We aimed to describe nutritional status and practices in children with severe bronchiolitis requiring admission to the pediatric intensive care unit (PICU), and explore their associations with outcomes. Methods We conducted a retrospective study on patients with bronchiolitis requiring PICU stay from 2009 to 2014. Demographics, medical data, and baseline weight‐for‐length Z‐scores (WLZ) were collected. In patients requiring more than 48 hours of PICU stay, nutritional intake data in the first 3 days of PICU stay were collected. Underfeeding and overfeeding were defined as the median energy intake of less than 80% and more than 120% of requirements, respectively. Protein adequacy was defined as intake of more than 1.5 g/kg/d. Primary and secondary outcomes of interest were the duration of PICU stay and mechanical ventilation (MV), respectively. Results Seventy‐four patients were included, with a median PICU stay of 4.9 days (interquartile range 2.0‐8.2). Low WLZ at baseline was associated with longer duration of PICU stay (adjusted β : 4.33 [95% confidence interval [CI], 0.49‐8.18]; P = .028) and MV days (adjusted β : 4.87 [95% CI, 1.56‐8.18]; P = .008) compared to appropriate WLZ. In patients with ≥48 hours PICU stay, protein adequacy was significantly associated with greater PICU (adjusted β coefficient, 6.35 [95% CI, 1.66‐11.0]; P = .009) and MV days (adjusted β coefficient, 5.22 [95% CI, 1.06‐9.38]; P = .015). Conclusion Among bronchiolitis patients admitted to the PICU, low WLZ at admission was associated with a longer duration of PICU stay and MV. Protein adequacy was associated with longer PICU and MV days in children with ≥48 hours of PICU stay.
