A smartphone app that identifies extreme jaundice in new child infants by scanning their eyes might be a life-saver in areas that lack entry to costly screening units, suggests a research co-authored by researchers at UCL (University College London) and the University of Ghana.
The app, known as neoSCB, was developed by clinicians and engineers at UCL and was used to display screen for jaundice in over 300 new child infants in Ghana, following an preliminary pilot research on 37 newborns at University College London Hospital (UCLH) in 2020.
For the large-scale research, printed in Paediatrics, the crew examined over 300 infants with the app, which analyses photos taken on a smartphone digital camera to quantify the yellowness of the white a part of the attention (sclera) – an indication of neonatal jaundice. Analyzing the yellowness of the attention simply by wanting is unreliable, and the neoSCB app can provide early prognosis of neonatal jaundice requiring remedy.
The research in contrast the effectiveness of the neoSCB app with typical screening strategies. Of the 336 infants examined by the app, 79 had been severely jaundiced newborns, and the app appropriately recognized 74 of them. This is according to the accuracy of the commonest typical screening technique, a non-invasive system often known as a transcutaneous bilirubinometer, which appropriately recognized 76.
The transcutaneous bilirubinometer works by measuring the yellow pigment below the new child’s pores and skin to present a measure of jaundice ranges. All screening outcomes are then adopted up by blood exams to find out the kind of remedy required.
Dr Terence Leung (UCL Medical Physics & Biomedical Engineering) who developed the expertise behind the app, stated: “The study shows that the neoSCB app is as good as commercial devices currently recommended to screen for severely jaundiced newborns, but the app only requires a smartphone which costs less than a tenth of the commercial device. We hope that, once rolled out widely, our technology can be used to save the lives of newborns in parts of the world that lack access to expensive screening devices.”
The neoSCB technique was acceptable to moms in city and rural communities the place the research was carried out. Mothers simply devised methods to maintain the infant’s eye open, most frequently by initiating breastfeeding.”

Jaundice, the place the pores and skin and whites of the attention flip yellow, is frequent in newborns and is often innocent. The yellowness is attributable to a substance known as bilirubin, which in extreme circumstances can enter the mind, resulting in dying or disabilities comparable to listening to loss, neurological situations comparable to athetoid cerebral palsy and developmental delays.
Every yr extreme jaundice causes about 114,000 new child deaths and 178,000 circumstances of incapacity worldwide, regardless of it being a treatable situation. Most circumstances of neonatal jaundice happen within the first week after delivery, and routine screening for early prognosis in increased earnings nations has decreased the dangers of extreme issues.
Newborns in low- and middle-income nations are usually at a higher threat of extreme jaundice, or neonatal hyperbilirubinemia, due to the dearth of sources required for screening. A business transcutaneous bilirubinometer usually prices round £4,000 per system, and blood exams require a considerable amount of capability. Additional elements comparable to a better prevalence of residence births and early postnatal discharge can contribute to fewer newborns going via screening.
Babies in sub-Saharan Africa are additionally at a higher threat due to a excessive prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency, which is an inherited genetic dysfunction related to an elevated threat of haemolysis – the place purple blood cells break down at a sooner fee than they’re made – and hyperbilirubinemia.
Senior creator Dr Judith Meek (UCLH) added: “This app has the potential to prevent death and disability worldwide in many different settings. It will reduce unnecessary hospital visits and potentially empower community health workers and parents to care for newborn babies safely.”
In complete, 724 newborns aged between 0 and 28 days had been initially thought-about for the research. The 336 whose datasets had been used for the paper had had no prior remedy for jaundice. Babies who had been born at lower than 35 weeks, had been critically sick or had a really low delivery weight had been excluded from the ultimate research. The app was examined with frontline healthcare staff and the infants’ moms, who offered suggestions on the usability of the app.
The research was supported by the Saving Lives at Birth consortium and the EPSRC UCL Centre for Doctoral Training in Intelligent Integrated Imaging in Healthcare.
