Variations in bronchopulmonary dysplasia prevalence and outcomes by definition: a multicentre cohort study from the Chinese Neonatal Network.

ABSTRACT:

Objectives

To examine bronchopulmonary dysplasia (BPD) epidemiological data in Chinese very preterm infants and compare agreement between four diagnostic definitions and their predictive accuracy for discharge outcomes.

Design

Observational epidemiologic study of a multicentre cohort of the Chinese Neonatal Network (CHNN).

Setting

Tertiary neonatal intensive care units participating in the CHNN.

Participants

42 664 preterm infants born at <32 weeks' gestational age from 2019 to 2023.

Measures

BPD was diagnosed using four definitions: Shennan 1988, the National Institute of Child Health and Human Development (NICHD) 2001 and 2018, and the Neonatal Research Network (NRN) 2019 definitions. BPD prevalence and severity were examined. Agreement was assessed us
