  • All variables listed are for the index admission. —, not applicable.

  • a Shown are percentages of readmitted patients within each grouping (eg, 68.3% of patients who were <12 mo old at index admission were readmitted, as compared to 31.7% who were not readmitted).

  • b Neurologic conditions included pre-existing diagnoses of anoxic brain injury, hypoxic-ischemic encephalopathy, epilepsy, muscular dystrophy, and quadriparesis.

  • c Other primary diagnosis categories included gastrointestinal, genetic and/or metabolic, orthopedic, renal, rheumatologic, and “symptoms.”

  • d Not all “ICU therapeutics” were recorded at all sites. The number of patients for whom data were collected is indicated for each variable.

  • e Median LOS was 38.3 d.
