BiliCalc 2.8

Designed by a pediatrician, BiliCalc utilizes the American Academy of Pediatrics 2004 guidelines for managing hyperbilirubinemia in infants over 35 weeks old. This application accurately calculates the threshold for initiating phototherapy based on a patient's age, bilirubin levels, and neurotoxicity risk, displaying values on the phototherapy nomogram. Moreover, it identifies the patient's risk zone using the Bhutani Nomogram.

BiliCalc offers the convenience of direct age input and includes a feature to calculate age from birth as well as lab sample times. It provides quick access to source journal articles, nomograms, and a list of neurotoxicity risk factors. The app supports both US and SI units (mg/dL and µmol/L).

App Feature Summary:

• Calculates phototherapy threshold for newborns 35 weeks and older
• Displays values on the phototherapy nomogram
• Suggests a timeframe for subsequent bilirubin level checks based on the patient's risk zone
• Features direct links to reference journal articles

Frequently Asked Questions:

1. I think the graph is backwards. Why is low risk at the top and high risk at the bottom?
   The graph aligns with the 2004 AAP Hyperbilirubinemia Guidelines. The term "risk" in this context pertains to an infant's likelihood of developing neurotoxicity, distinct from how it is used in the Bhutani Nomogram where it signifies the potential for severe hyperbilirubinemia. The treatment threshold varies depending on predisposing factors across three risk categories. Infants with "low neurotoxicity risk" can tolerate higher bilirubin levels than those classified as medium or high risk. Therefore, high-risk infants require treatment at lower bilirubin levels compared to low-risk infants. The graph correctly positions low risk at the top as higher values are necessary to cross the treatment threshold (phototherapy). You can verify this graph here.

This application is tailored for pediatricians, neonatologists, physicians, medical students, and pediatric nurses managing newborns both in hospital settings and as outpatients.
