  • DE, deterioration event; NA, not applicable.

  • a Table displays n (%) for categorical variables, mean (SD) for continuous variables.

  • b P for the comparison of data collected from patients who did and did not experience qualifying deterioration events within 12 h of a nonelective transfer to the PICU.

  • c Aggressive fluid hydration defined as >60 mL/kg fluid bolus given.

  • d Nonparametric Wilcoxon rank-sum test due to skewed distribution.

  • e Fisher’s exact test due to small cell size.
