Background: Infants with Bronchopulmonary Dysplasia (BPD) are often prescribed diuretics before the neonatal intensive care unit (NICU) discharge. It is unknown whether outpatient medication weaning strategies affect duration of home oxygen therapy. Methods: This was a secondary cohort analysis of infants born <32 weeks gestational age with BPD from 2015-2018 discharged from our NICU or regional NICUs, referred to our pulmonary clinic for home oxygen management. We compared three groups: those discharged with no diuretics, diuretics actively weaned (dose decreased) and diuretics passively weaned (dose not adjusted). Results: Out of 125 infants, 116 were included in the analysis. Forty-five infants were discharged without diuretics; 52 infants were discharged with diuretics that were actively weaned; 19 infants were discharged with diuretics that were passively weaned. Infants who were passively weaned spent the most time on home oxygen (median 28 weeks, IQR 16-52; p=0.011); there were no differences in home oxygen duration in infants actively weaned (median 13 weeks, IQR 10-26) versus not on diuretics (median 22 weeks, IQR 12-30, p=0.285). Multivariable adjustment for other illness characteristics associated with duration of home oxygen did not change this finding. Conclusions: Active weaning of diuretics did not prolong duration of home oxygen, in the setting of a standardized clinical guideline for weaning home oxygen in infants with BPD. These data can serve as baseline information to implement and test standardized strategies for outpatient medication management.
