A Multicenter Initiative for Critical Congenital Heart Disease Newborn Screening in Texas Neonatal Intensive Care Units

Objective The objective of this study was to implement a strategy for critical congenital heart disease (CCHD) newborn screening in the neonatal intensive care unit (NICU). Design A NICU-specific curriculum, screening algorithm, slide presentations, and templates of orders, policies, and procedures were developed into a toolkit for training NICU personnel. Screening was conducted on first and second screen pre- and postductal oxygen saturations (SpO ₂) on newborns admitted or transferred to the NICU. Results We trained 347 NICU personnel in 13 Texas hospitals, representing rural, suburban, and metropolitan settings. Key hospital staff submitted deidentified, case-based screening data. Of 4,621 NICU admissions, 80% received a first screen. Second screening rates were substantially lower in all gestational age groups. Screening rates on first and second screens were lowest among infants born < 28 weeks. For the first screen, SpO ₂ was lowest among the youngest gestational ages. The false positive rate was 2.3%. Conclusion CCHD screening in the NICU is challenging, given the complexities of the NICU population. A modified screening protocol that recognizes special circumstances of neonatal intensive care could facilitate a more efficient system.
