Hospital Variation and Risk Factors for Bronchopulmonary Dysplasia in a Population-Based Cohort

Abstract

Bronchopulmonary dysplasia or death prior to 36 weeks' postmenstrual age affects approximately 45% of VLBW infants across California. The wide variability in BPD occurrence across hospitals could offer insights into potential risk or preventive factors. Additionally, our findings suggest that increased regionalization of NICU care may reduce BPD among VLBW infants.
