The Health eTime submission for the Department of Veterans Affairs’ 21st Century Medical Scheduling America Competes Contest (Challenge.gov) represents the result of a highly successful agile software development collaboration effort between MedRed LLC and BT America. Our open-source product is available to the medical-software development community for collaboratively incremental refinement and continuous sustainability. The application facilitates the lifecycle management of individual and group patient appointments from booking, canceling, and rescheduling, through to completion and the recording of appointment outcomes. It’s designed to augment functionality currently provided through the legacy VistA scheduling module. The application is oriented and organically integrated with VistA as the system of record.
