Study Participants
This retrospective cohort study identified all infants with a primary diagnosis of moderate or severe CNLD, who required home oxygen therapy, and were managed at the Queensland Children’s Hospital (QCH) between January 2016 and December 2017. All infants were managed according to the standard home oxygen protocol within our center (Appendix 1). Demographic and clinical information was obtained from the patient’s integrated electronic medical record (iEMR). Post-discharge clinical variables were collected until the infants reached 24 months chronological age. Small for gestational age (SGA) was defined as being less than 10th percentile for birth weight using the Fenton preterm growth chart.11 This study was approved by the Children’s Health Queensland Hospital and Health Service Human Research Ethics Committee.
