Objective: To determine costs of hospitalization associated with bronchopulmonary dysplasia (BPD) during the first year in very low birth weight infants. Study design: Retrospective cohort study of California births from 2008 to 2011 linking birth certificate, discharge records, and clinical data from California Perinatal Quality Care Collaborative. Inclusion: birth weight 401–1500 g, gestational age < 30 weeks, inborn or transferred within 2 days, alive at 36 weeks corrected, and without major congenital anomalies. Outcomes included cost and length of stay of initial hospitalization and rehospitalizations. Result: Out of 7998 eligible infants, 2696 (33.7%) developed BPD. Median hospitalization cost in the first year was $377,871 per infant with BPD compared with $175,836 per infant without BPD (adjusted cost ratio 1.54, 95% confidence interval (CI) 1.49–1.59). Infants with BPD also had longer length of stay and a higher likelihood of rehospitalization. Conclusion: BPD is associated with substantial resource utilization. Prevention strategies could help conserve healthcare resources.
