Abstract:
Neonatal jaundice is a condition that affecting around 60 percent of all newborns and is
characterized by a buildup of the yellow pigment, bilirubin, in the blood. While the jaundice condition
can recede naturally and may not cause any discomfort or harm, high levels of bilirubin associated with
jaundice can cause brain damage or even death if left untreated. In the US, non-invasive screening for
jaundice with an optical bilirubinometer is part of the standard of care, however the cost of these devices
limits their availability to resource-constrained areas of the world. In designing a low-cost, mobile
phone-based bilirubinometer, we aim to:

prototype a software application that measures skin reflectance at 2 wavelengths from a mobile
phone-based camera

ensure safety via built-in functions to quantify adequate camera performance and detection

test the software on a range of commonly available phone models and on infants of various skin
tones that are afflicted with the condition
Introduction:
Neonatal jaundice, or neonatal hyperbilirubinemia, is a yellowing of the skin, appearing in
newborn children with excess amounts of bilirubin in their blood. Bilirubin develops as the byproduct
of normal heme catabolism and, thus, can develop in excess for numerous reasons such as increased red
blood cell volume, increased bilirubin circulation, or ineffective secretion via bile. For most infants,
jaundice develops mostly because of the elevated amounts of unconjugated bilirubin during the first
week; this cause is also referred to as physiological jaundice and can be quite common and oftentimes
even normal.
Although many infants are born with hyperbilirubinemia due to the normal hemolysis of red
blood cells that were necessary for fetal circulation before birth, pathological jaundice can persist in
some infants, causing a much more serious diagnosis, resulting in severe and permanent brain damage or
even death. To be clinically declared as pathological jaundice, there are four main parameters, only one
of which must be met. First, the infant can exhibit jaundice within the first 24 hours or after the first 14
days of life. The second criterion is an increase in bilirubin of more than 8.5 mg/dL per hour. Third,
jaundice is diagnosed if the total concentration of bilirubin is greater 19.5 mg/dL at any point in the
infant’s life. Finally, the fourth measure is if the direct concentration of bilirubin is greater than 2.0
mg/dL. Because of these four parameters, our experiment will focus on children greater than 14 days to
ensure that we are testing for pathological jaundice and not physiological jaundice.
In determining whether or not an infant’s condition can be classified as pathological jaundice or
not, most of the conditions listed above require invasive methods. Another, non-invasive option
for determining jaundice is with an Ingram icterometers which directly measure the yellowness of
the infant’s skin. In the United States, these devices are quite commonplace and are typical in the
standard of treatment of newborns. Because of their cost, however, these devices or far less
available in low-income resources and remote locations. The prohibitive nature of these devices is
especially unfortunate because of how simply jaundice can be treated, infants usually requiring
treatment as simple as extra sunlight or changes in breastfeeding.
In order to supply low-income and low-resource areas with a better standard of care for all
newborn infants, our team has several aims for our project. First, our main goal is to develop a
software application that can determine jaundice within infants using skin reflectance with as few
as two different wavelengths via a mobile-phone camera. Second, we want to ensure safety
through verifying accurate camera performance and detection. Finally, we aim to carry this study
into trial studies, attempting to use the program on several different phone models when looking
at infants afflicted with this condition. Through our research, development, and trials, we hope to
better guarantee higher quality of care for all newborn infants
Team:
Our team consists of five undergraduate seniors: Christina Baker, Giselle Fontela, Pierce Jones,
Brendan Lynch, and Sloan Sypher. All members are majoring in Biomedical Engineering and have
acquired extensive knowledge in various physiological processes, signal analysis, and computer
programming. In fact, one of our group members, Brendan Lynch, has had experience with mobile
phone programming for games and basic applications. He also has a strong background in software
development. Another group member, Giselle Fontela, has had three summers worth of experience in
various kinds of signal analyses in a research laboratory setting. Christina Baker has also acquired signal
analysis skill in a research laboratory setting. Pierce Jones has taken several classes in instrumentation,
medical imaging, and human physiology. He has also has research experience on campus, working in a
clinical setting.
Sloan Sypher has been involved in Searle Systems Biology and Bioengineering
Undergraduate Research Experience (SyBBURE) and has had imaging experience using Image J. Two
group members, Christina Baker and Sloan Sypher, are minoring in Engineering Management. The
knowledge that they have acquired through the required courses for the minor will provide our team
with expertise in development and marketing strategies. In addition to her minor, Sloan has internship
experience with patent search of analogous technologies and mapping of market environments of
competitor products and technologies. It should be noted that as project develops, more specific roles
will be assigned to each group member based on their skills. For further background on each group
member, reference Appendix A.
Our team will be working under Dr. Chetan Patil, a Research Assistant Professor of Biomedical
Engineering. He is a member of the Biomedical Optics Laboratory and has recently been awarded a
grant from the Bill & Melinda Gates Foundation to develop this particular project. Mapping of
competitive technologies
History and Context:
Previous Work and Current Progress:
On May 9, 2012, Dr. Patil was awarded a $100,000 grant from the Bill & Melinda Gates
Foundation to test the ability of an adapted mobile phone to diagnose jaundice in newborns in
developing countries.
Dr. Patil is working on testing the flash and detector response of phones commonly available in
the developing countries. The phone’s camera and simple applications are used to detect levels of
bilirubin through the skin, which allows for a diagnosis to be made so that treatment as simple as
increased exposure to sunlight can begin.
Target Market
The target market will depend on the accuracy and sensitivity of the device. Initially the target
market is hospitals, clinics, and expecting family members in resource-constrained settings. Although
for the purpose of our own research and prototyping we will be introducing our product to the local area,
the specific grant from the Gates Foundation, our product will later be introduced to sub-Saharan Africa
and is meant for that area. To this extent, all phones, software, and testing will be geared towards this
ultimate target market of sub-Saharan Africa.
The device being a software package on commonly available mobile phones means that
everyone from the doctors and nurses to the infant’s parents could purchase the software if they have the
right phone. Furthermore, if the device can prove to be on the same order of accuracy as the current
optical bilirubinometer then the target market will increase to areas outside low-resource settings.
Work Plan and Outcomes:
See Appendix B for Gantt Chart.
First, the team must characterize the response curve of the smartphone camera by
conducting a series of tests in the biomedical optics laboratory at Vanderbilt University. Then we
will calculate a logarithm, which normalizes the results to a 1:1 ratio to the white light spectrum. If
need be, lenses will be utilized to select for the specific wavelengths of interest. Then we will
compile data in order to create a Weiner Estimation that will serve as a reference to diagnose
pathological jaundice from the smartphone application. After we have compiled this data, we will
present it to the team of computer scientists that will program the application to run on the
Android platform used on the top smartphones in Sub-Saharan Africa. By the end of the year, the
application should be fully functional and field ready.
Evaluation, Sustainability Plan:
This device would be more sustainable if it were programmed to run on a variety of
different smartphone platforms (iPhone, Android, HTC, etc) so that patients would be able to use
the program on their own device without making the trip to a clinic or physicians office.
Additionally, environmental considerations such as the conservation of paper and other naturally
derived resources should be considered. One such method of conservation would be to administer
diagnoses of positive neonatal jaundice results electronically.
Also, it is important that the
application has an innate trouble-shooting function that sends error reports in order to analyze
bugs in the application before failure occurs.
Budget:
Any necessary funding will be provided for by a $100,000 grant received by Dr. Chetan
Patil from the Bill and Melinda Gates Foundation.
