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 ).
