Early iron supplementation and iron sufficiency at one month of age in NICU patients at-risk for iron deficiency.

In order to reduce iron deficiency in neonates at-risk for iron deficiency, we implemented a guideline to increase the consistency of early iron supplementation in infants of diabetic mothers, small for gestational age neonates and very low birthweight premature neonates. Three years following implementation we performed a retrospective analysis in order to assess adherence to the guideline and to compare timing of early iron supplementation and reticulocyte-hemoglobin (RET-He) values at one month of life in at-risk infants. Adherence with early iron supplementation guidelines was 73.4% (399/543) with 51% (275/543) having RET-He values obtained at one month. Despite good adherence, 16% (44/275) had RET-He <25 pg (5th percentile for gestational age). No infants receiving red blood cell transfusion (0/20) had RET-He <25 pg vs. 26.1% (40/153) of those treated with darbepoetin (p < 0.001). There was no evidence of increased feeding intolerance (episodes of emesis/day) with early iron supplementation.
