Variation in pediatric medical care is common and contributes to differences in patient outcomes.
Site-to-site variation in the characteristics and care of infants with neonatal opioid withdrawal syndrome (NOWS) has yet to be quantified.
Our objective was to describe site-to-site variation in maternal-infant characteristics, infant management, and outcomes for infants with NOWS.
Cross-sectional study of 1377 infants born between July 1, 2016, and June 30, 2017, who were ≥36 weeks’ gestation, with NOWS (evidence of opioid exposure and NOWS scoring within the first 120 hours of life) born at or transferred to 1 of 30 participating hospitals nationwide.
Site-to-site variation for each parameter within the 3 domains was measured as the range of individual site-level means, medians, or proportions.
