Study population
During the study period, 665 cases were included. A total of 85 infants
received escalated care, of which 34 (40%) were treated with HFNC, 2
(2.4%) received non-invasive ventilation, 6 (7.6%) were mechanically
ventilated, and 43 (50%) received conventional oxygen therapy. The
characteristics of the infants who did and did not receive escalated
care and the bivariable associations between postulated predictors and
escalated care appear in Table 1.
