Insights
Most premature infants with severe bronchopulmonary dysplasia (BPD) survive hospitalization. The majority of these infants with severe BPD are discharged by 44 weeks postmenstrual age.
Area of Science:
- Neonatology
- Pediatric Pulmonology
- Perinatology
Background:
- Bronchopulmonary dysplasia (BPD) is a chronic lung disease affecting premature infants.
- Severe BPD presents significant challenges in neonatal intensive care units (NICUs).
Purpose of the Study:
- To characterize the in-hospital outcomes of premature infants diagnosed with severe bronchopulmonary dysplasia (BPD).
Main Methods:
- Retrospective cohort study.
- Data collected from 348 NICUs within the Pediatrix Medical Group from 1997 to 2015.
- Included premature infants diagnosed with severe BPD.
Main Results:
- 10,752 infants with severe BPD were identified.
- Mortality rate before discharge was 5% (549 infants).
- Infants who died were more likely to be male, small for gestational age, and have comorbidities like surgical necrotizing enterocolitis, sepsis, and pulmonary hypertension.
Conclusions:
- Most infants with severe BPD are discharged by 44 weeks postmenstrual age (70%) or 48 weeks (86%).
- Findings can help inform discussions with families about the expected hospital course.
- Understanding outcomes is crucial for managing severe BPD in premature infants.
Objective:
To characterize in-hospital outcomes of premature infants diagnosed with severe bronchopulmonary dysplasia (BPD).
Study Design:
Retrospective cohort study including premature infants with severe BPD discharged from 348 Pediatrix Medical Group neonatal intensive care units from 1997 to 2015.
Results:
There were 10 752 infants with severe BPD, and 549/10 752 (5%) died before discharge. Infants who died were more likely to be male, small for gestational age, have received more medical interventions and more frequently diagnosed with surgical necrotizing enterocolitis, culture-proven sepsis and pulmonary hypertension following 36 weeks of postmenstrual age compared with survivors. Approximately 70% of infants with severe BPD were discharged by 44 weeks of postmenstrual age, and 86% were discharged by 48 weeks of postmenstrual age.
Conclusions:
A majority of infants diagnosed with severe BPD were discharged home by 44 weeks of postmenstrual age. These results may inform discussions with families regarding the expected hospital course of infants diagnosed with severe BPD.
