Abstract
Differences in the diagnostic approach to bronchopulmonary dysplasia (BPD) may contribute to variation in reported BPD rates. We undertook a nationwide survey of UK neonatal units (NNUs) to describe criteria applied by neonatologists to conduct pulse oximetry studies in ex-preterm infants to assess their need for supplemental oxygen near discharge, as well as criteria applied to interpret saturation studies. Responses from 112 (64.7%) NNUs demonstrated wide variation in both criteria used to select infants for assessment and thresholds for interpretation. Neither demonstrated a clear relationship with reported BPD rates. Variation in clinical practice requires further scrutiny to inform and streamline management of ex-preterm infants at risk of BPD, and potentially improve outcomes.
