Abstract
The study aim was to predict, using serum bilirubin, level measured 18 to 24 hours (SB, 18–24) after birth, the occurrence of peak serum bilirubin level >15 mg/dL (hyperbilirubinemia) or the requirement of phototherapy, any time from the second to fifth postnatal day. The study was conducted on a prospective cohort of 274 neonates born in north India. The main outcome measures were (a) hyperbilirubinemia and (b) phototherapy.
Serum bilirubin level was estimated at 18–24 hours of age and then daily from second to fifth postnatal day. Exclusion criteria were Rh incompatibility, asphyxia and life threatening congenital malformations; and neonates of women with gestational diabetes or history intake of drugs affecting the fetal liver.
Hyperbilirubinemia was found in 12.8%; and 19.3% neonates received phototherapy. Dichotomous SB 18–24, using a cut-off of >3.99 mg/dL, as the “prediction test” had the following sensitivity and specificity for predicting (a) hyperbilirubinemia: 67% and 67%, respectively, and (b) the treatment with phototherapy: 64% and 68%, respectively.
We concluded that by using SB 18–24 as the “prediction test”, approximately two-thirds of neonates were test negative and had about one in ten chances of re-admission for treatment of hyperbilirubinemia, if discharged. After further validation, our results will be of benefit to neonates delivered in developing countries.
