Chang 2017 three-variable rebound hyperbilirubinemia score
Chang 2017 three-variable rebound hyperbilirubinemia score: +15 if GA <38 weeks, −7 × age at phototherapy start in days, −4 × (caller AAP phototherapy threshold − TSB at termination), +50. Scores <20 correspond to a <4% chance of TSB returning to threshold within 72 hours. magent does not assay bilirubin or compute the AAP nomogram. Not Chang 2019. Not a phototherapy order.
