Kevin, I work with these systems in the VA all the time and we don't have that magic HL7 syncing system.
We generally run a cluster of servers, sometimes with a backup set in case the main cluster goes down. But data entry in two databases at the same time and an attempt to sync up later just wouldn't work (duplicate IENs for notes, labs, etc.) in our current environment. Have you been able to isolate where the speed problem occurs? Does CPRS run fast in the server room but not at the remote site? Have you monitored the network traffic between server and remote site? In Chicago I ran another whole tertiary care medical center and a large (150 staff) Outpatient Clinic off of one set of servers located at a third location. CPRS response time was identical at all 3 sites... D Beard --- Kevin Toppenberg <[EMAIL PROTECTED]> wrote: > I am have a big problem with CPRS being slow.
