Gtk# EHR for interfacing with VistA based systems (Medsphere OpenVista, VA's VistA, etc.) OpenVista CIS is a rewrite of the Department of Veteran Affairs' Computerized Patient Record System (CPRS) in Gtk#. The focus is on using a modern language, internationalization, and cross-platform support.
NOTE: To use the application, you will need a running instance of a VistA based server to connect to. The application is not standalone, and will not even let you log in without a server to connect to.
