Retrospective study found no relationship between COI and oxygen duration in preterm infants with BPD, suggesting need for further exploration.
This study aimed to evaluate the association between the Child Opportunity Index (COI) and postdischarge oxygen use in infants with bronchopulmonary dysplasia (BPD). Retrospective study of infants < 32 weeks' gestation with BPD, discharged on home oxygen from 2010 to 2022 and followed in a BPD clinic. Primary outcome was duration of oxygen use, secondary outcomes were emergency room (ER) visits, missed BPD appointments, and readmission. Of 145 infants included in the study, 88 (60.3%) infants were in the very low COI category. Mean (standard deviation) duration of home oxygen was 89.5 (92) days. Regression analysis did not show any significant association between COI and duration of home oxygen use. Number of ER visits, unplanned readmissions, and missed BPD appointments also did not vary significantly between the COI groups. Our study did not show any significant association between COI and duration of home oxygen use in infants with BPD.
