- Importance: Bronchopulmonary dysplasia (BPD) is the most common serious morbidity of preterm birth. Short-term respiratory outcomes for infants with the most severe forms of BPD are highly variable. The mechanisms that explain this variability remain unknown and may be mediated by racial disparities.Objective: To determine the association of maternal race with death and length of hospital stay in a multicenter cohort of infants with severe BPD.Design, setting, and participants: This multicenter cohort study included preterm infants enrolled in the BPD Collaborative registry from January 1, 2015, to July 19, 2021, involving 8 BPD Collaborative centers located in the US. Included patients were born at less than 32 weeks' gestation, had a diagnosis of severe BPD as defined by the 2001 National Institutes of Health Consensus Criteria, and were born to Black or White mothers.Exposures: Maternal race: Black vs White.Main outcomes and measures: Death and length of hospital stay.Results: Among 834 registry infants (median [IQR] gestational age, 25 [24-27] weeks; 492 male infants [59%]) meeting inclusion criteria, the majority were born to White mothers (558 [67%]). Death was observed infrequently in the study cohort (32 [4%]), but Black maternal race was associated with an increased odds of death (adjusted odds ratio, 2.1; 95% CI, 1.2-3.5) after adjusting for center. Black maternal race was also significantly associated with length of hospital stay (adjusted between-group difference, 10 days; 95% CI, 3-17 days).Conclusions and relevance: In a multicenter severe BPD cohort, study results suggest that infants born to Black mothers had increased likelihood of death and increased length of hospital stay compared with infants born to White mothers. Prospective studies are needed to define the sociodemographic mechanisms underlying disparate health outcomes for Black infants with severe BPD.

Journal article (peer-reviewed)abstract
- Improved survival of extremely preterm newborn infants has increased the number of infants at risk for developingbronchopulmonary dysplasia (BPD). Despite efforts to prevent BPD, many of these infants still develop severe BPD (sBPD) andrequire long-term invasive mechanical ventilation. The focus of research and clinical management has been on the prevention ofBPD, which has had only modest success. On the other hand, research on the management of the established sBPD patient hasreceived minimal attention even though this condition poses large economic and health problems with extensive morbidities andlate mortality. Patients with sBPD, however, have been shown to respond to treatments focused not only on ventilatory strategiesbut also on multidisciplinary approaches where neurodevelopmental support, growth promoting strategies, and aggressivetreatment of pulmonary hypertension improve their long-term outcomes. In this review we will try to present a physiology-basedventilatory strategy for established sBPD, emphasizing a possible paradigm shift from acute efforts to wean infants at all costs to amore chronic approach of stabilizing the infant. This chronic approach, herein referred to as chronic phase ventilation, aims atallowing active patient engagement, reducing air trapping, and improving ventilation-perfusion matching, while providingsufficient support to optimize late outcomes.
