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.
