A better understanding of the incidence and processes leading to kernicterus may help in the design of preventive measures.<h4>Objectives</h4>To determine incidence rates of hazardous hyperbilirubinemia and kernicterus among near-term to term newborns and to evaluate health care professional adherence to best practices.<h4>Design, setting, and participants</h4>This population-based nationwide cohort study used prospectively collected data on the highest serum bilirubin level for all infants born alive at 35 weeks' gestation or longer and admitted to neonatal care at all 46 delivery and 37 neonatal units in Sweden from 2008 to 2016.
