Checking neonates' Bilirubin levels is a daily occurrence in the nursery in the days following birth with the incidence of neonatal jaundice in term infants being 50% and in preterm babies 80%.

This app calculates an infant's threshold for beginning phototherapy from his or her age, bilirubin level, and risk using the American Academy of Pediatrics 2004 “Management of Hyperbilirubinemia in Infants Greater than 35 Weeks of Age”. The results are displayed on the phototherapy nomogram as well as Risk Assessment and Exchange Therapy nomograms.

Schneezie ,

Top notch!!!

As a physician who had a Bili-baby and used this tool first hand, I highly recommend it! It is incredibly useful and adding new values is very easy to do.

The phototherapy/risk/exchange plots are high quality and accurate. I was able to send screenshots to family to help keep everyone in the loop for progress.

My one critique would be that transitioning between the risk level text and actual plots was not intuitive at all and I almost missed the functionality entirely. The user interface needs to be adjusted to make it more obvious that you can scroll through. Yes there is a dot, but there should be an additional 3 unfilled dots next to it to show there are a total of 4 options to scroll through.

Must have been designed by someone who actually sees newborns. It’s intuitive, quick and practical. A+!!!

Useful but interface a little clunky

Helpful app but UI isn’t the best - text boxes sometimes don’t respond and the link to further information doesn’t work. Overall not bad for a free calculator though

Developer Response ,

Hi Noah, Thanks for the feedback! Would you mind giving us a few more details by emailing bilibabyapp@gmail.com about what text boxes aren't working for you and what mobile OS you're using? We'd love to hear any other ideas about UI improvements as well!
