GNUmed has been around a while. Most communication happens via the mailing list. Not everyone is comfortable with mailing lists and users tend to stay away from it. That is why we are planning a get together in Leipzig, Germany.
This is a 220-bed government facility. In December 2011/January 2012 about 9,000 feet of Ethernet and Fiber Optic cable was laid. 3 servers were delivered: OpenEMR, backups, IM, Internet access and firewall. Also installed are UPS, power conditioners, 5 switches and 20 laptops.
While not exclusively a Gnu-Linux product (runs on LAMP and WAMP stacks), the selection of OpenEMR by the Peace Corps for its worldwide EMR needs, lends a powerful measure of legitimacy and value to the use of open source EMRs in general and OpenEMR specifically. .
