Maternal detection of neonatal jaundice during birth hospitalization using a novel two-color icterometer.

Mothers are frequently the first to observe the onset of jaundice in their newborn infants before the decision to seek treatment. However, simple-to-use tools that could facilitate early detection of jaundice and assist mothers to seek professional care, especially after hospital discharge, are rare. This study therefore, set out to evaluate the performance of a -two-color icterometer (Bilistrip™) as a possible screening tool for detecting significant jaundice by mothers or care-givers in the first week of life.Prior to discharge, mothers in a maternity hospital were trained to use the Bilistrip™ on the blanched skin of their baby's nose to ascertain absence (Light Yellow) or presence (Dark Yellow) of significant jaundice. Their babies had transcutaneous bilirubin (TcB) measurements independently, along with total serum bilirubin (TSB) if indicated. The reliability of Bilistrip™ as a screening test for significant jaundice was determined at different TcB and TSB thresholds. The predictive performance of Bilistrip™ was also evaluated with multivariable logistic regression.Some 2492 mother-infant pairs were enrolled over 15 months, of which 347 (13.9%) chose Dark Yellow. The mean TcB for Dark Yellow (10mg/dL) was significantly higher (p
