Abstract

OBJECTIVE: To evaluate the association between the time of first systemic corticosteroid initiation and bronchopulmonary dysplasia (BPD) in preterm infants.

STUDY DESIGN: A multi-center retrospective cohort study from January 2010 to December 2016 using the Children's Hospitals Neonatal Database and Pediatric Health Information System database was conducted. The study population included preterm infantsweeks' gestation treated with systemic corticosteroids after 7 days of age and before 34 weeks' postmenstrual age. Stepwise multivariable logistic regression was used to assess the association between timing of corticosteroid initiation and the development of Grade 2 or 3 BPD as defined by the 2019 Neonatal Research Network criteria.

RESULTS: We identified 598 corticosteroid-treated infants (median gestational age 25 weeks, median birth weight 760 g). Of these, 47% (280 of 598) were first treated at 8-21 days, 25% (148 of 598) were first treated at 22-35 days, 14% (86 of 598) were first treated at 36-49 days, and 14% (84 of 598) were first treated at >50 days. Infants first treated at 36-49 days (aOR 2.0, 95% CI 1.1-3.7) and >50 days (aOR 1.9, 95% CI 1.04-3.3) had higher independent odds of developing Grade 2 or 3 BPD when compared to infants treated at 8-21 days after adjusting for birth characteristics, admission characteristics, center, and co-morbidities.

CONCLUSIONS: Among preterm infants treated with systemic corticosteroids in routine clinical practice, later initiation of treatment was associated with a higher likelihood to develop Grade 2 or 3 BPD when compared to earlier treatment.
