Respiratory trajectory and risk of death or moderate-to-severe bronchopulmonary dysplasia in very preterm infants: a nine-year cohort study
To evaluate factors associated with death before 36 weeks’ postmenstrual age (PMA) or moderate-to-severe bronchopulmonary dysplasia (BPD) in very preterm infants, explicitly accounting for survivor bias.
Key Findings:
Composite outcome of death before 36 weeks’ PMA or moderate-to-severe BPD occurred in 27.1% of 1,253 infants analyzed.
Risk of the composite outcome decreased with advancing gestational age, from 80.2% in infants born at <26 weeks to 11.7% at 30–31 weeks (p < 0.001).
Each additional week of gestation was associated with lower odds of the composite outcome (aOR: 0.85, 95% CI: 0.77–0.94).
Cumulative duration of invasive ventilation (aOR: 1.29 per 7 days, 95% CI: 1.14–1.45) and HFOV exposure (aOR: 1.79, 95% CI: 1.15–2.79) were associated with the composite outcome.
Interpretation:
Lower gestational age and prolonged invasive ventilation were principal factors associated with death or moderate-to-severe BPD, with implications for clinical management of very preterm infants.
Limitations:
Study conducted at a single center, which may limit generalizability.
Data derived from a retrospective analysis, which may introduce biases.
Potential confounding factors not controlled for in the analysis.
Conclusion:
The study highlights the importance of gestational age and invasive ventilation duration in predicting adverse outcomes in very preterm infants.
