A core outcome set for perinatal interventions in congenital diaphragmatic hernia
Thank you for your collaboration on the core outcome set (COS) for perinatal interventions for congenital diaphragmatic hernia (CDH).
As part of the development of this COS, 221international stakeholders participated in an online Delphi survey to select potential core outcomes. During the Consensus Meeting following the 5th ERNICA Annual Meeting in Lille (France), 93 stakeholders eventually agreed on eight core outcomes:
Maternal morbidity
Gestational age at delivery
Intra-uterine death
Interval between intervention and delivery
Lung development in utero
Neonatal mortality
Pulmonary hypertension
Use of extracorporeal membrane oxygenation (ECMO)

In a final Definition meeting, we will discuss how to define and measure each of these outcomes. Aspirational outcomes, which will not be part of the COS yet are recommended to report, will be also discussed.
We would like to invite you to participate in one of these 1-hour online Definition Meetings. We will offer three options to accommodate for different time zones. Please register for all dates you could participate to such meeting; we will select one out of these.
