Objective: To implement a neonatal iron deficiency (ID) guideline as part of a neuroprotective strategy using reticulocyte hemoglobin content (RET-He) for neonates born <33 weeks postmenstrual age (PMA) and small for gestational age (SGA) neonates ≥33 weeks PMA, to achieve ≥80% screening rate by June 2024. Methods: An interdisciplinary team conducted a quality improvement initiative in a level III neonatal intensive care unit (NICU) from April 2022 to August 2024. RET-He is a validated, sensitive marker of early iron deficiency reflecting recent iron supply for erythropoiesis and providing a more reliable measure than ferritin. The primary outcome was RET-He screening at 30 ± 7 days for neonates <33 weeks PMA or pre-discharge for SGA neonates ≥33 weeks PMA. Exclusion criteria were death or transfer before eligibility. Process measures included ID screening failure rate (RET-He level < 29 pg). Results: Of 345 eligible neonates, P-chart analysis showed screening rates for premature neonates <33 weeks PMA declined during PDSA 1–2, before improving to 85.9% in PDSA 3. ID screening failure was 12.6% at one month, increasing to 32.1% at two months. For SGA neonates ≥33 weeks PMA, screening rates remained low, peaking at 36% in PDSA 3, with a 2.2% failure rate. Conclusions: Implementation of a RET-He based ID guideline improved screening rates for premature neonates but was less effective for SGA neonates. Despite improved guideline adherence, ID prevalence remained high at NICU discharge, indicating a further need to improve nutritional prevention and treatment strategies.
