Newborn Weight Tool (NEWT) on FHIR
summary
A SMART on FHIR app connects the NEWT API to EHR data to show hour-by-hour newborn weight nomograms so clinicians can spot risky weight loss without leaving the chart. It handles inconsistent newborn fields by using launch parameters and optional in-app checkboxes, was demoed by swapping sandbox teen data for realistic newborn data, the prototype is ~140 lines of code (production <100), and security is simplified by hosting app and API together; adoption interest is high.
