AI-ML prediction of Neonatal Sepsis
Neonatal Sepsis kills overs 6 lakh neonates (0-29 days) in India alone every year. Infants born in rural areas of India are particularly affected due to lack of comprehensive diagnosis methods. Critical issues in diagnosis of Neonatal Sepsis are limitations of current culture tests, difficulty to obtain an infant’s blood, delayed diagnosis, antibiotic resistance, low access to healthcare in rural areas and low affordability. Our innovation, PreSco, is a mobile application that can be easily deployed on field to predict outcome of babies with risk of onset of neonatal sepsis. PreSco provides an early assessment of neonatal sepsis by generating a risk score based on the input values. The most important use of the application is that it can stratify babies into low, medium and high risk. Such a classification enables a health worker to administer antibiotics rationally. PreSco is particularly effective in resource-constrained countries and can save lives.
PreSco provides a neonatal sepsis score which is an early indicator of risk of onset of sepsis. This score can be generated multiple times for a continuous assessment of a baby till it is either free from risk or is provided with the right treatment. The risk score generated can be transmitted to the nearest referral doctor / centre along with the list of parameters for a further assessment or expert opinion. In low resource countries like India, rural health infrastructure is not strong. However, at least 50% cases can be handled by rural clinics itself. Every year, India gets about 25 million newborns and close to 10 million of them are located at the bottom of pyramid. The government newborn care system is able to provide care to only about 1 million babies. Our solution is effective in resource-constrained areas. It provides cost advantage, rapid assessment, integrates rural healthcare, frontline healthcare volunteers and doctors with urban network. With an early assessment, frontline health volunteers, rural doctors and rural clinicians can begin pre-emptive assessment, begin related therapy, make multiple assessments, or as a last resort, make an informed decision on antibiotic administration.
Our innovation, PreSco (Predictive Scoring) is a cloud-based machine-learning platform. It is a web responsive application that can be easily deployed on mobiles on the field to predict outcome of babies with risk of onset of neonatal sepsis. It deploys specialized machine learning algorithms that are able to generate probabilities of neonatal medical conditions like sepsis infections, pneumonia, meningitis (broadly classified under the umbrella of neonatal sepsis), in babies through multiple data points collected across various time intervals. A typical challenge in healthcare prediction of events lies in handling multiple records of patients without losing out on information from any single record which we are addressing using innovative machine learning techniques that can handle longitudinal / real-time data. We have developed a prototype of an integrated cloud platform for predictive risk scoring of neonatal sepsis. It consists of a data collection application and machine learning algorithms for three different levels of score generation – 1. Frontline Healthcare 2. Primary and Secondary and 3. Tertiary. A data collection application with multiple screens for various types of health parameters (maternal and infant) has been developed. An ensemble of machine learning algorithms has been used for building the predictive model.
Currently, the per capita cost of providing neonatal care in India is estimated to be around USD 187 while the annual cost is about USD 19,381. Additionally, it is estimated that about 11 to 23 babies receive antibiotics for 1 culture positive. Going by the lower bound, antibiotics can be reduced by at least 10-fold saving USD 143 million by using our machine learning platform. In addition to that, the platform ensures overall cost effectiveness in treatment through reduction in antibiotic usage, hospital stay charges in NICU when the algorithms provide low risk of sepsis by at least 50%. Additionally, culture tests for diagnosing neonatal sepsis take at least 48 – 72 hours. This time period is very critical for a neonate as it can deteriorate very fast because of low immunity. While administering an empirical antibiotic is safe choice, this practice has become rampant and has led to an increase in antibiotic resistance and is killing many babies. Hence, there is a need for a rapid and comprehensive test during the first 24 to 48 hours during which a baby is suspect to have neonatal sepsis. Our platform addresses this issue by running predictive algorithms.
- Expand access to high-quality, affordable care for women, new mothers, and newborns
As per United Nation’s Sustainable Development Goal 3.2, neonatal mortality rate NMR for India should be 12 by 2030. It is currently high at 25. Rural health network in India has 82% shortage of specialists. More than 40% of neonatal deaths are reported to occur within first 24 hours of admission due to absence of health facilities at rural areas and subsequent transport to urban centres. At least 80% parents shift or drop treatments for their babies mid-way because of high costs. Through PreSco, we are providing an affordable and accessible platform to address the issue.
- Prototype: A venture or organization building and testing its product, service, or business model
- A new application of an existing technology
We have adopted a novel approach to address the issue of diagnosis of Neonatal sepsis. Currently, diagnosis is made on the basis of blood tests, including culture tests, which are time consuming. Facilities for these tests are not available at all clinics, hospitals, especially in semi-urban or rural areas. It is extremely critical to diagnose neonatal sepsis in the early hours as a neonate’s condition deteriorates very fast. Our platform is based on machine learning. It detects the onset of neonatal sepsis in the early hours by mapping non-invasive parameters and providing a risk score. Bases on the risk score, a health practitioner can decide whether to begin treatment or not. This platform uses the power of machine learning to provide predictive analysis which is in itself the innovative feature of our platform.

Research from developed countries has demonstrated high effectiveness in decision making by including machine learning algorithms for diagnosing suspect sepsis at least 4 hours before clinical suspicion in developed countries. However, an existing scoring application, the Kaiser Permanante score developed in the USA uses prior probability for building the algorithm. Since the incidence of neonatal sepsis is high in India, Kaiser’s calculator is not likely to be effective as it does not factor in regional epidemiological variation. Our algorithms overcome this limitation. Kaiser Permanante’s scale focuses on prediction of early onset of sepsis (EOS) using maternal factors. Our approach uses infant and maternal factors for predicting both onset of early as well as late onset of sepsis. Kaiser’s scale is developed at tertiary level. Our algorithms are at three levels and are designed to work in low resource settings with open source software for cost optimization and improving affordability, access and connectivity.
Additionally, open source technologies offer greater transparency and interoperability, along with the advantage of low cost. Most of the current COVID self testing apps launched in many countries across the globe such as the UK, Israel, India etc are based on open source technologies and they have been working well.
