why survival in our cohort was higher overall, but limited information
about the nature of CPR received and its duration in our database may
have lead us to capture less severe or shorter CPR episodes associated
with improved outcomes. Survival following either delivery room or
NICU CPR has been consistently higher in more mature or higher BW
infants [2,5]. This was also the case in our study, but we observed
highest survival rates (86%) in the 33–36 weeks GA cohort, with somewhat
lower survival in infants N36 weeks GA (62%). We hypothesize
that selection bias may explain this finding: most full-term infants
do not require NICU admission unless they suffer from a pre- or postnatal
diagnosis, while several near-term (33–36 weeks GA) infants
may be admitted simply for monitoring. This is supported by the fact
that in our study, infants N36 weeks GA were more likely to suffer a
congenital anomaly compared to those 33–36 weeks GA (14% vs. 8%).
