New App Enables Parents to Test Babies for Jaundice at Home

A groundbreaking mobile application, BiliSG, promises to revolutionize the way parents monitor their newborns for jaundice, a condition affecting up to 60% of full-term babies and 80% of premature ones. This innovative solution harnesses artificial intelligence and machine learning to provide accurate bilirubin level predictions, offering convenience and peace of mind to parents from the comfort of their homes.

Understanding Neonatal Jaundice

Neonatal jaundice is a common condition that manifests as a yellowish discoloration of the skin and eyes in newborns. It results from elevated levels of bilirubin, a yellow pigment produced during the natural breakdown of red blood cells. While the condition is generally mild and resolves within two to three weeks, severe jaundice can lead to serious complications such as intellectual disabilities, developmental delays, and motor impairments if left untreated. Early detection and monitoring are therefore critical to preventing these outcomes.

Traditional vs. App-Based Jaundice Testing

Current methods for jaundice testing typically involve using a handheld device to measure skin yellowness or obtaining a blood sample through a heel prick. While effective, these methods require a visit to a healthcare provider, which can be inconvenient and stressful for parents and infants alike.

The BiliSG app simplifies this process by analyzing photos of a baby’s forehead, chest, and abdomen using specialized color-calibration stickers. Its machine learning algorithm processes the images to assess the degree of yellowness and predict bilirubin levels. This approach ensures accurate results across various Asian ethnicities and skin tones, addressing the limitations of existing apps that rely on a single point of reference or are designed for non-local populations.

Development and Validation

BiliSG was developed by a multidisciplinary team from the Singapore General Hospital (SGH), SingHealth Polyclinics (SHP), and the national health tech agency Synapxe. The app underwent rigorous testing in a study involving nearly 550 newborns between November 2023 and June 2024. Results demonstrated its accuracy in detecting significant jaundice cases, aligning closely with traditional testing methods. The findings, published in the peer-reviewed journal JAMA Network Open in December 2024, validate the app’s efficacy and reliability.

Key Advantages of BiliSG

• Convenience: Parents can monitor their baby’s jaundice at home, reducing the need for frequent clinic visits.
• Inclusivity: The app accounts for diverse skin tones and ethnicities, ensuring accurate results for Asian populations.
• Comprehensive Analysis: Unlike other apps that rely on a single measurement point, BiliSG evaluates multiple body areas to provide a detailed assessment.
• Enhanced Monitoring: Parents can collaborate with family doctors via telemedicine, ensuring continuous care and supervision.

Future Developments

Although the app is currently optimized for a single smartphone model, developers plan to expand its compatibility over the next 18 months. This includes testing on 2,000 additional babies across various smartphone models, operating systems, and camera specifications. Enhancements to support a broader range of skin tones are also in the pipeline, further improving its accessibility and accuracy.

Potential Impact on Infant Care

Clinical Associate Professor Tan Ngiap Chuan, SHP’s research director and senior author of the study, described BiliSG as a “game changer in infant care.” By enabling parents to monitor jaundice conveniently and reliably, the app has the potential to transform newborn care practices. It bridges the gap between traditional clinical testing and modern digital health solutions, offering a user-friendly interface backed by cutting-edge AI technology.

Andy Ta, Synapxe’s chief data officer, highlighted the app’s role in leveraging AI to improve healthcare accessibility. “The development of the BiliSG app illustrates how we can empower parents to monitor their infant’s jaundice from the comfort of their homes,” he said.

Challenges and Considerations

While promising, the app’s success will depend on its ability to maintain high accuracy across diverse conditions and user scenarios. Factors such as lighting, photo quality, and correct use of calibration stickers could influence results. Comprehensive user education and ongoing refinements to the algorithm will be essential to address these challenges.

Moreover, integrating the app into healthcare workflows, including telemedicine consultations, will require collaboration between developers, healthcare providers, and regulatory authorities. Ensuring data privacy and security will also be critical as the app handles sensitive health information.

Availability

BiliSG is expected to be commercially available within two years, following extensive testing and refinement. Once launched, it could serve as a model for similar AI-driven healthcare applications, fostering innovation in patient-centric solutions.

Conclusion

The development of the BiliSG app represents a significant step forward in neonatal care. By combining machine learning with user-friendly technology, it empowers parents to monitor their babies’ health effectively and conveniently. As it undergoes further testing and enhancement, BiliSG has the potential to set a new standard in managing neonatal jaundice, ensuring healthier outcomes for infants worldwide.
