Neonatal Jaundice Risk Assessment (Bhutani Nomogram)

Assesses risk of significant hyperbilirubinaemia in newborns using hour-specific total serum bilirubin (TSB) plotted on the Bhutani nomogram. Guides phototherapy and exchange transfusion decisions.

Score interpretation

Low Zone — Low Risk

→ Low zone (TSB in low-risk range for age): Low risk of significant hyperbilirubinaemia. Routine monitoring; ensure adequate feeding (8–12 feeds/day); reassess bilirubin in 24–48 hours if discharged.

Low-Intermediate Zone

→ Low-intermediate zone: Low-intermediate risk. Plot on Bhutani nomogram with hour-specific value. Reassess before discharge; outpatient TSB check at 24–48 hours. Promote breastfeeding support.

High-Intermediate Zone — Consider Phototherapy

→ High-intermediate zone: Elevated risk. Initiate phototherapy if TSB above NICE threshold for gestational age at this hour. Check: blood group, DAT (Coombs), G6PD in at-risk populations; FBC. Review risk factors.

High Zone — Phototherapy / Consider Exchange Transfusion

→ High zone (TSB ≥256 μmol/L or term neonate): High risk. Intensive phototherapy immediately. If TSB at exchange threshold (typically >450 μmol/L in term, lower in preterm): emergency exchange transfusion. NICU admission. Urgent haematology. Check G6PD deficiency.
