Clinical Trial Summary

The purpose of this study is to Determine if deimplementation of iNO in the post-natal resuscitation/stabilization phase affects the composite outcome of ECLS use and/or mortality, as well as ECLS use, mortality, and/or oxygenation in CDH newborns and to establish the cost-effectiveness of deimplementing iNO as a therapy in the postnatal resuscitation/stabilization phase of CDH management, which will be assessed as the incremental health system costs (savings) per prevented ECLS use and/or death.

Description:

In this multi-center study, centers will use iNO per their usual protocol, and centers will then crossover to iNO de-implementation (that is, at the time of crossover, centers will stop using iNO in the initial resuscitation period). A stepped-wedge crossover study design will be used, and the timing of crossover will be cluster randomized at the level of the center.

Intervention

Drug:
• Inhaled Nitric Oxide (iNO) use
The center will use iNO per their usual protocol in the initial resuscitation period (defined as birth through stabilization and CDH repair). No center will alter any component of their standard clinical practice guideline or protocol governing CDH care.

Other:
• De-implementation of Inhaled Nitric Oxide (iNO) use
The center will stop using iNO in the initial resuscitation period (defined as birth through stabilization and CDH repair).
