Well, you'd think standards and compliance would make it easy, but that assumes when people say they meet the standard... they ACTUALLY meet the standard. Format is one thing, but ensuring correct sequence and field validation is something else entirely. Unlike HTTP and the internet, in health there are no business drivers for integration compliance.
On the contrary - large companies (like Cerner) who can offer an "all-in-one-integrated-solution" benefit from the lack of conformance. The real obstacle is not setting up trusted health vaults, that's the easy part. The difficulty is populating it with live information, from live systems, with full trust.
Of course, that's before you mention terminology. Does a haemoglobin result mean the same thing from two different lab systems? How about normal ranges? Blood glucose or urine glucose? Presenting complaint vs discharge diagnosis? I'm not trying to be overly pessimistic, but this is a much more difficult problem than simply sticking up a database somewhere.
