REDCap to Epic interfaces create an efficient hybrid software solution for a public health registry.

A public health registry and intervention was created in response to the Flint water crisis to identify and refer exposed individuals to public health services to ameliorate the deleterious impact of lead exposure. Traditional technology architecture domains, funded scope of work, as well as community input were considered when defining the requirements of the selected solutions. A hybrid software solution was created using Research Electronic Data Capture (REDCap) to deploy an open participant survey and bypass requirements to create user accounts, and Epic to manage deduplication and participant communication and tracking. To bridge the two software systems, REDCap to Epic unidirectional ADT and Documentation Flowsheet interfaces were built to automate creation of subject records in Epic identical to those created in REDCap and to copy key protocol-driving variables from REDCap to Epic. The interfaces were critical to deliver a successful hybrid solution in which the desired features of each software could be leveraged to satisfy specific protocol requirements and community input. Data from the start of survey administration (December 2018) through 31 December 2020 are reported to demonstrate the usefulness of the interfaces.
