OpenVista is an open source electronic health record (EHR) system developed by MedSphere Systems Corporation, based on the U.S. Department of Veterans Affairs (VA) VistA system. OpenVista supports the clinical workflow of hospitals and ambulatory care facilities through seven foundational applications: the Clinical Information System (CIS); the Health Information Management System (HIMS); Laboratory, Pharmacy, Radiology, Nutrition & Food Service; and the OpenVista Interface Suite.

The combination of core clinical support functionality and the ever-expanding Interface Suite enables OpenVista to interoperate with a facility's legacy applications in creating a comprehensive electronic patient care solution. Medsphere has significantly expanded VistA functionality in creating OpenVista. The company has added clinical flowsheet, patient tracking, and has updated the pharmacy graphical user interface (GUI) and database capability, making OpenVista more responsive to the commercial health care environment.
