Background: Hyperbilirubinaemia is a common cause of hospital admission of newborn infants; however, maternal visual assessment of jaundice may reduce unnecessary hospital visits. Aims: To investigate the validity of maternal visual assessment of neonatal jaundice to identify infants with hyperbilirubinaemia requiring phototherapy or who have significant hyperbilirubinaemia ≥239.4 µmol/L (14 mg/dL). Methods: A prospective study of the diagnostic accuracy of maternal visual assessment of jaundice was conducted at a university hospital in Bangkok. Mothers were trained to assess for neonatal jaundice using their infant’s palms as a skin colour reference. Trained mothers who were blinded to transcutaneous bilirubin or serum bilirubin values assessed their infants and reported ‘jaundice’ or ‘no jaundice’, and determined jaundice severity using dermal icterus zones. Sensitivity and negative predictive values were used to assess the validity of visual assessment for neonatal jaundice. Results: In 180 mothers, the median (min/max) transcutaneous or serum bilirubin value in their infants was 177.8 µmol/L (119.7–309.5). The sensitivity and negative predictive values (95% CI) of maternal assessment for detecting hyperbilirubinaemia requiring phototherapy were 91.7% (73.0–99.0) and 96.6% (87.9–99.1), respectively, and for identifying significant hyperbilirubinaemia were 92.9% (76.5–99.1) and 96.6% (87.9–99.1), respectively. The accuracy of maternal report of dermal zones for serum bilirubin levels was only 44.5%. In 56 infants who received a second jaundice assessment, the sensitivity of maternal assessment for detecting increased transcutaneous or serum bilirubin was 93.9% (83.1–98.7). Conclusion: Teaching mothers to visually assess their infants for neonatal jaundice was demonstrated to be feasible.
