Likelihood of weaning supplemental oxygen in a given month, in the outpatient setting
In a multivariate model, the likelihood of being weaned off supplemental oxygen in a given month was lower if the child was prescribed more supplemental oxygen initially, had a gastrostomy tube, had a lower estimated household income, or was prescribed inhaled corticosteroids (Table 2 ). Interestingly, severity of BPD at 36 weeks corrected age did not influence the likelihood of weaning off supplemental oxygen in a given month.
Acute care usage and respiratory outcomes, with regard to level of supplemental oxygen at initial hospital discharge .
We next examined correlations between outpatient respiratory outcomes and acute care usage with the level of supplemental oxygen use at initial hospital discharge. When examining differences by amount of oxygen at initial discharge, we found no significant differences in acute care usage, chronic respiratory symptoms, or rescue medication use (Table 3 ).
