Newborn Screening Data on FHIR

Background

The Utah Newborn Screening Program collects a variety of demographic data from the screening specimen that is sent in for a newborn. Often the data collected is missing or inaccurate. In order to complete the data and/or ensure accuracy, the Utah Newborn Screening Program compares this data against the Utah Office of Vital Records and Statistics data from birth and death certificates. The current process is antiquated and would benefit from the usage of a newer technology like FHIR. The full specification can be retrieved here.

This application provides an FHIR interface to compare the data between the Utah Newborn Screening Program and the Utah Office of Vital Records and Statistics.
