A neurologic dysfunction scoring protocol for jaundiced neonates requiring exchange transfusion.

AIM

To evaluate the performance of a neurologic assessment protocol among jaundiced infants requiring exchange transfusion (ET).

METHODS

We identified infants in a referral children's hospital who received ET and those who met the American Academy of Pediatrics (AAP) criteria for ET based on total serum bilirubin (TSB) levels. The performance of a bilirubin-induced neurologic dysfunction (BIND-M) scoring protocol for acute bilirubin encephalopathy (ABE) in detecting infants treated with ET in both groups was investigated by logistic regression analysis and c-statistic.

RESULTS

A total of 438 late-preterm and term infants were enrolled, out of which 141 (32.2%) received ET, and 155 (35.4%) met AAP criteria for ET. Infants with BIND-M scores of 3-6 (intermediate ABE) or 7-12 (advanced ABE) were significantly associated with ET in both groups, but not scores of 1-2 (mild ABE), with or without adjustment for confounding neurotoxicity risk factors. However, the discriminatory ability of BIND-M regression models was modestly satisfactory (c-statistic range: 0.693-0.791).

CONCLUSIONS

Our findings suggest that BIND-M is a potentially useful decision-making tool for ET and support current recommendation for immediate ET for infants with intermediate-to-advanced stages of ABE regardless of the TSB levels.
