Conclusion
This prospective study of children with a tracheostomy found that the diagnosis of BPD was associated with an increased time to decannulation as well as an increased duration of mechanical ventilation. While bronchopulmonary dysplasia alone was associated with a decreased hazard ratio for mortality, the added presence of pulmonary hypertension was associated with an increased hazard ratio for mortality. Further investigation using multinstituonal data to explore and corroborate these findings would be valuable.
