Janus is a graphical user interface (GUI) and a front-end web application that enables DoD and VA providers to exchange critical patient information through a common real-time data view of patient information from the separate and distinct EMR systems of the two departments, i.e. AHLTA & VistA. The Hawaii Resource Group LLC has provided guidance, leadership, development team members, and support services for the joint VA/DoD 'open source' Janus software project. The software has been contributed to the Open Source Electronic Health Record Agent (OSEHRA) for distribution.
