  • aOR, adjusted odds ratio; —, not applicable.

  • a Manual backward selection procedure was used. Variables included in full model were as follows: age; sex; race and/or ethnicity; language; ED visit in the previous year; asthma sick visit in the previous year; previous PICU admission; asthma severity; history of asthma comorbidity; controller medication prescribed at discharge; postdischarge visit scheduled; and index hospitalization APR-DRG severity of illness. Variables that were significant (α < .05) in the final model are presented. The model including language was a significantly better fit than the model excluding language when using the likelihood-ratio test.

  • b Fisher’s exact test.

  • c Asthma comorbidity was defined as a condition that leads to more complicated asthma, including the presence of obesity, allergic rhinitis, eczema, gastroesophageal reflux disease, and/or obstructive sleep apnea.18
