Subject Demographics
At initial hospital discharge, children who required higher levels of
supplemental oxygen were more likely to have severe BPD, lower
birthweight percentiles, and a diagnosis of pulmonary hypertension
compared to those who required less supplemental oxygen (Table
1 ). Additionally, higher levels of supplemental oxygen at initial
hospital discharge were associated with older age at discharge
(p<0.001), gastrostomy tube placement (p<0.001), and
use of diuretics (p=0.005), inhaled corticosteroids (ICS) (p=0.005), and
pulmonary anti-hypertension medications (p<0.001).
Race/ethnicity and public insurance were not associated with higher
supplemental oxygen use at initial hospital discharge; however, there
was some variation in oxygen amounts by median household income
(p=0.042).
