ObjectivesTo compare the time to asthma-related readmissions between children with a previous ICU hospitalization for asthma and those with a non-ICU hospitalization and to explore predictors of time to readmission in children admitted to the ICU.DesignRetrospective cohort study using a pan-Canadian administrative inpatient database from April 1, 2008, to March 31, 2014.SettingAll adult and pediatric Canadian hospitals.SubjectsChildren 2-17 years old with a hospitalization for asthma.InterventionsNone.Measurements And Main ResultsA total of 26,168 children were hospitalized 33,304 times during the study period. The time to readmission was shorter in the ICU group compared with the non-ICU group (median time to readmission 27 mo in ICU vs 35 mo in non-ICU group). Preschool-aged children (hazard ratio, 1.48; 95% CI, 1.02-2.14) and increased length of stay (hazard ratio, 1.63; 95% CI, 1.17-2.27) were associated with a shorter time to readmission.ConclusionsChildren previously admitted to the ICU for asthma had a shorter time to asthma-related readmission, compared with children who did not require intensive care, underlining the importance of targeted long-term postdischarge follow-up of these children. Children of preschool age and who have a lengthier hospital stay are particularly at risk for future morbidity.
