Pathak et al developed a nomogram to identify a north Indian neonate at risk for significant hyperbilirubinemia. This can help to identify a neonate who may need more aggressive management. The authors are from Government Medical College in Chandigarh, India.
Patient selection: neonate from north India
Outcome: significant hyperbilirubinemia with need for phototherapy
Parameters:
(1) time since birth (from 6 to 200 hours)
(2) predischarge serum total bilirubin in mg/dL
Nomogram shows 3 risk lines:
(1) 40th percentile
(2) 75th percentile
(3) 95th percentile
