Is the hour-specific bilirubin nomogram suitable for predicting hyperbilirubinemia

Area of Science:

• Neonatology
• Pediatrics
• Clinical Chemistry

Background:

• Hyperbilirubinemia is a common condition in newborns.
• Predictive tools are essential for managing neonatal jaundice.
• The Bhutani et al. nomogram offers hour-specific risk stratification.

Purpose of the Study:

• To evaluate the efficacy of the Bhutani et al. hour-specific serum bilirubin nomogram.
• To predict significant hyperbilirubinemia in term Turkish newborns.
• To assess the nomogram's utility in clinical practice for this population.

Main Methods:

• Study included 217 healthy term Turkish newborns without hemolysis.
• Serum bilirubin levels measured at discharge and upon observation of jaundice.
• Infants categorized into risk zones (high, intermediate, low/high, low) using the nomogram.
• Follow-up assessments conducted between 7–10 days of life.

Main Results:

• Mean predischarge bilirubin: 9.71±3.4 mg/dL.
• 16.6% of infants received phototherapy; none required exchange transfusion.
• Higher risk zones correlated with increased phototherapy rates (OR: 24.5–83.6).
• Increased gestational age reduced phototherapy risk (OR: 0.35 per week).

Conclusions:

• The Bhutani et al. hour-specific nomogram accurately predicted significant hyperbilirubinemia in Turkish term newborns.
• The nomogram is a valuable tool for risk assessment and management of neonatal jaundice in this population.
• Utilizing this nomogram can help guide appropriate clinical decisions and prevent severe outcomes.
