Rationale and Comments
The risk of poor neurologic outcomes, such as cerebral palsy due to kernicterus, is extremely low for term and late preterm newborns with modestly elevated bilirubin levels. Confirmed cases of kernicterus have average bilirubin levels near 40 mg/dL, and are typically associated with hemolysis. While phototherapy for bilirubin values above published thresholds may be useful to prevent severe hyperbilirubinemia and exchange transfusions, its use for bilirubin values below published thresholds is unnecessary and is associated with additional costs and unnecessary hospitalization.
