Trends in BPD Data Over 9 Years in a Single Tertiary Surgical Neonatal Centre

Background: Incidence of significant bronchopulmonary dysplasia (BPD) in babies born

Objective:

• To observe trend of rates of significant BPD and survivals in babies born at

• To determine which gestation category (23-25+6, 26-28+6, 29-31+6) had the significant change in incidence of significant BPD

• To compare rates of significant BPD in babies who were transferred to local hospital before 36 weeks against to babies who were still at the St Georges hospital at 36 weeks corrected gestation.

Methods: It was retrospective cohort study reviewing babies born at

Babies were transferred Ex-Utero to St. George’s Neonatal unit were excluded from the study.

Results: Between 2010-2018 there were 727 live births < 32 weeks gestation at St. George’s hospital NHS trust. Average incidence of BPD over nine years was observed to be 42%. Incidence of BPD was observed to be increasing from 29% in 2010 to 51% in 2018. We Observed increased BPD rates in gestational group (26 -28+6 (33% in 2010 to 44% in 2018) and gestational group 29-31+6 (19% in 2010 - 24% in 2018).

Conclusions: Rates of significant BPD in babies born
