Comparison of two transcutaneous bilirubinometers in term and near-term neonates

Purpose: Determination of bilirubin levels is performed for many newborns in the first days of life, and several different transcutaneous bilirubinometers are available. We aimed to determine whether transcutaneous bilirubin measurement, as performed using Jaundice Detector JH20-1C, a new device, correlates with Minolta/Hill-Rom Air-Shields Transcutaneous Jaundice Meter model JM-103.Design and Sample: The study was performed on term or near-term newborn infants who underwent transcutaneous bilirubin measurements as part of their normal care. The study group consisted of 585 newborn infants with gestational ages ranging from 35 to 42 weeks, coming from an uneventful pregnancy. In this prospective study, bilirubin concentrations were determined with two different transcutaneous bilirubinometers.Main Outcome Variable: In 585 infants, the correlation coefficient for Jaundice Detector JH20-1C versus Minolta Air-Shields Jaundice Meter model JM-103 was .965 (p < .0001). The mean (± standard deviation) difference between the Jaundice Detector JH20-1C versus Minolta Air-Shields Jaundice Meter model JM-103 was 0.26 ± 0.95 mg/dL. Results showed the Jaundice Detector JH20-1C to have an acceptable level of intradevice imprecision (r = .978, p < .0001, mean differences .0158 ± .871 mg/dL).Results: Jaundice Detector JH20-1C showed the good performances of intradevice and interdevice imprecision in comparison with Minolta/Hill-Rom Air-Shields Transcutaneous Jaundice Meter model JM-103. Jaundice Detector JH20-1C may be suitable for screening term or near-term newborn infants for jaundice in the well-baby nursery or maternity ward.
