Bilirubin Measurement Through a Smartphone Application in Preterm Infants.
Klinische Pädiatrie 2022 December 21
BACKROUND: Aim of the present study is to evaluate the feasibility and reliability of an smartphone application for monitore of bilirubin levels in preterm infants.
METHODS: Preterm infants hospitalized in the neonatal intensive care unit with gestational age of<35 weeks were included. Exclusion criteria were parental reluctance and requirement of phototherapy in the last 12 hours. Measurements were obtained through a smartphone application (BiliScan) along with simultaneous transcutaneous device (Dräger JM 105) and venous blood biochemistry.
RESULTS: Mean gestational age was 30.8±2.4 weeks and birth weight was 1622±566 g. Measurements were obtained at a median of 4 (1-21) days of life. Twenty-five infants (19.4%) had ABO and/or Rh incompatibility and 39 infants (30.2%) required phototherapy. None of the cases required exchange transfusion. Mean total serum bilirubin (TSB) level was 8.16±2.60 mg/dL, mean transcutaneous bilirubin (TcB) level was 8.60±2.70 mg/dL, and the mean bilirubin level measured by BiliScan was 7.26±2.68 mg/dL. For TSB and TcB measurements, the intraclass correlation coefficient (ICC) was found to be 0.915 (95% confidence interval 0.835-0.951; p<0.001) and a strong positive correlation was found between these two measurements. When TSB and BiliScan measurements were compared, ICC was found to be significant as 0.512 (95% confidence interval 0.353-0.638; p<0.001), with a moderate correlation.
CONCLUSIONS: In this study, we evaluated the feasibility and reliability of a smartphone application for monitoring bilirubin levels in preterm infants. Although BiliScan measurements reported to display high correlation in term infants, a moderate correlation was found in the preterm infants. It is an emerging low-cost, non-invasive alternative for neonatal jaundice monitoring, however, results should be interpreted with caution in preterm infants.
