OBJECTIVE:To evaluate the impact of statewide learning collaboratives that used national guidelines to manage jaundice on the serial prevalence of extreme hyperbilirubinemia (EHB, total bilirubin ≥ 25 mg dl- 1) and exchange transfusions introduced in California Perinatal Quality Care Collaborative (CPQCC) hospitals in 2007.STUDY DESIGN:Adverse outcomes were retrieved from statewide databases on re-admissions for live births ≥ 35 weeks' gestation (2007 to 2012) in diverse CPQCC hospitals. Individual and cumulative select perinatal risk factors and frequencies were the outcomes measures.RESULTS:For 3 172 762 babies (2007 to 2012), 92.5% were ≥35 weeks' gestation. Statewide EHB and exchange rates decreased from 28.2 to 15.3 and 3.6 to 1.9 per 100 000 live births, respectively. From 2007 to 2012, the trends for TB425 mg dl- 1 rates were - 0.92 per 100 000 live births per year (95% CI: - 3.71 to 1.87, P = 0.41 and R2 = 0.17).CONCLUSION:National guidelines complemented by statewide learning collaboratives can decrease or modify outcomes among all birth facilities and impact clinical practice behavior.
