[FOSS_health] VistA and HL7

[Lee Seldon]

Here is a document describing (the original) VistA's involvement with 
HL7 messaging.

Called "Generic HL7 Interface Handbook"
I assume that this would also apply to World VistA, but it would be good 
to get confirmation from there.

PS: A student of mine in the USA writes
"Since the funding for my-health-e-vet was canned by congress 
(my-health-e-vet was to replace VistA) facilities are now looking to 
purchase vendor systems to run in conjunction with Vista / CPRS to 
extract the stored data within VistA modules but to provide the end user 
with a friendlier interface.  I guess what I am saying is that VistA / 
CPRS is great for administrative / financial management and serves the 
purpose for outpatient / doctor office longitudinal electronic health 
record but fails for the documentation / data intense acute inpatient 
applications."
