Technically it's delimited by whatever character is decided to be the delimiter, which is even better :) Having said that, it still seems to get data between all sorts of systems in the hospital.

In my experience with HL7 it's a standard, but every single system you talk to you need to write custom code to handle them, because everyone talks the "standard" a bit differently. [edit] and as for the XML v3, nobody uses it. Nobody.

  Absolutely (for both points). I found HL7v2 to be more of a 'standard of communication of data' as opposed to a 'standard of data'. A lot of the work I did in my last job was dealing with these differences... I think the best investment of my time was the code I wrote to more easily interact with the messages, just to help alleviate those differences. All in all, very fun times :)

That I think is the key distinction: HL7 works okay for a group of tightly coupled systems, usually internal to a single organization. The biggest problems today are with data interchange between providers, networks of providers, 3rd party vendors (cloud based or whatever) and the like. The finance and insurance industry have, I think, figured this out. Healthcare has not.

  That's a good point and to be honest, I didn't deal much with things outside of the hospital itself (I mainly worked in the ADT 'sphere') but I could see how the 3rd party stuff could get hairy... especially if they're trying to deal with different message formats within the same facility.

lol, yeah, im sure it works. it isn't json tho... you could also say Cache (it's a post-relational database... whatever that means) is a standard database used in medical systems, but it sure isn't a postgres.

  It is an object database which was all the rage back in 1996-ish. I had to use it outside of the medical market once and the sales manager was shocked!
