Abstract
Objective Little data are available regarding erythropoietin (Epo) utilization patterns within
neonatal intensive care units (NICUs). We sought to describe the trends in Epo utilization
across a large cohort of U.S. NICUs.
Study Design This is a retrospective cohort study of infants discharged from 2008 to 2017 using
the Pediatrix Clinical Data Warehouse.
Results We identified 704,159 eligible infants from 358 sites, of whom 9,749 (1.4%) had Epo
exposure. For extremely low gestational age newborns (ELGANs), Epo exposure ranged
from 7.6 to 13.5%. We found significant site variability in Epo utilization in ELGANs.
Among the 299 NICUs caring for ELGANs during the study period, 184 (61.5%) never used
Epo for this population, whereas 21 (7%) utilized Epo in 50% or more of eligible infants.
Epo was initiated at a median of 25 days in ELGANs. For infants with hypoxic–ischemic
encephalopathy (HIE), Epo exposure remained ≤1% through 2014 then increased fourfold
to 3.4% by 2017. The median day of Epo initiation was the day of birth for infants
diagnosed with HIE.
Conclusion Epo is utilized in ELGANs more commonly than for other NICU populations. Utilization
patterns appear to indicate the treatment of established anemia for ELGANs and more
recently for neuroprotection in patients diagnosed with HIE.
