Objective

To discover a predictor, that could be used at least 3 to 4 weeks' before discharge, to identify infants who would need home oxygen therapy. We hypothesized that infants requiring a high level of respiratory support at 34 weeks' postmenstrual age (PMA) would require home oxygen.

Study design

Single center retrospective study of 143 infants less than 28 weeks' gestation. We determined when infants weaned from each level of respiratory support (mechanical ventilation, nasal continuous airway pressure [nCPAP] or biphasic positive pressure, nasal cannula flow ≥ 2 L/min, nasal cannula flow < 2 L/min or no respiratory support). Our primary outcome was need for home oxygen.

Result

Infants who required nCPAP at 34 weeks' PMA had a 100% positive predictive value for home oxygen therapy.

Conclusion

Higher levels of respiratory support at 34 weeks' PMA can predict the need for home oxygen and is useful in preparing patients and families for discharge.
