Background:
Kernicterus resulting from excessive bilirubin concentrations can be effectively prevented by early diagnosis and therapy. The postnatal rise of bilirubin peaks at a time of life most newborn infants have been discharged home while the next scheduled well baby visit is several weeks ahead.
Aim:
Evaluating a post-discharge bilirubin follow-up program established in 2010.
Methods:
Retrospective analysis of newborns seen 2010-2024 at the Berlin University Medical Center bilirubin outpatient clinic, exchange transfusions performed in the same time period, and infants admitted for phototherapy in 2022.
Results:
The median annual number of infants consulting the outpatient clinic was 616 in 2010-2016, as compared to 1858 in 2017-2024. In 2022, 6% of newborns seen at the outpatient clinic were admitted for treatment of hyperbilirubinemia at a median age of 6 [5-7] days, with a total serum bilirubin concentration of 20.5 [19.3-21.4] mg/dl). The 2 top indications for the 81 exchange transfusions performed in 78 patients were rhesus incompatibility (n=44; 56%) and gestational alloimmune liver disease (n=24; 31%). The bilirubin level immediately prior to exchange transfusion was 15.5 [12.5-20.0] mg/dl (highest measured value 38.1 mg/dl).
Conclusion:
A post-discharge program attached to a neonatal unit can effectively bridge the gap in care between discharge and scheduled well-baby visits several weeks ahead. A mandatory U2a could standardize follow-up care for neonatal hyperbilirubinemia in the future.
