Insights
Routine 24-hour bilirubin screening effectively identifies newborns needing phototherapy (PT) within 24 hours. This screening is crucial for timely jaundice management and preventing severe hyperbilirubinemia in neonates.
Area of Science:
- Neonatal care
- Pediatric gastroenterology
- Clinical diagnostics
Background:
- Hyperbilirubinemia is a common neonatal condition.
- Early identification of jaundice is critical for preventing kernicterus.
- Phototherapy is a standard treatment for significant neonatal jaundice.
Purpose of the Study:
- To evaluate the effectiveness of jaundice surveillance and 24-hour bilirubin screening.
- To determine the utility of these methods in identifying neonates requiring phototherapy within 24 hours of birth.
Main Methods:
- Retrospective, single-center observational study.
- Analysis of 6098 neonates born at ≥35 0/7 weeks gestation.
- Review of total serum bilirubin (TSB) levels, blood type, and direct antiglobulin test (DAT) results.
Main Results:
- 1.0% (59/6098) of neonates qualified for phototherapy (PT) at ≤24 hours.
- 83% of these neonates were identified via 24-hour bilirubin screening.
- A significant proportion of neonates requiring PT had TSB levels approaching or exceeding exchange transfusion thresholds.
Conclusions:
- 24-hour bilirubin screening is highly effective in identifying neonates needing early phototherapy.
- Routine screening within 24 hours of birth is recommended for timely jaundice management.
- This approach aids in preventing severe hyperbilirubinemia and its complications.
Objective:
To assess the utility of jaundice surveillance and routine 24 hour bilirubin screening in identifying neonates who qualify for phototherapy (PT) at ≤24 hours after birth.
Study Design:
In this retrospective, single-center observational study, records of neonates ≥350/7 weeks gestation born to O+, antibody negative mothers (n = 6098) were screened to identify who received PT at ≤24 hours after birth. The hour specific TSB at which neonates qualified for PT, blood type, direct antiglobulin test (DAT), and whether treatment was triggered by jaundice detection at <24 hours or the 24-hour bilirubin screen were determined.
Results:
59 neonates (1.0%) qualified for PT ≤ 24 hours after birth; 10 (17%) were identified by jaundice detection at <24 hours, whereas 49 (83%) were identified on 24-hour bilirubin screening. Forty-eight of the 59 (81%) were ABO incompatible and DAT+; 11 were DAT negative, one of whom had glucose-6-phosphate dehydrogenase deficiency. Among the ≤24 hour PT group, 17 had a PT qualifying TSB within 3 mg/dL of exchange transfusion (ET); 14 of whom were only identified first on 24-hour bilirubin screening. Six exceeded ET thresholds, 4 of whom were identified on 24-hour bilirubin screening.
Conclusions:
Neonates who qualified for PT at ≤24 hours were identified mostly by 24-hour bilirubin screening, a fraction of whom had a TSB that approached or exceeded ET thresholds. Our findings support routine birth hospitalization bilirubin screening and suggest screening no later than 24 hours after birth may be beneficial.
