Yeah, that pesky proprietary XML. Too bad there's no standard for it in healthcare![emoji12] [emoji12] [emoji12]

HL7 is a joke when one wants the true data...it's an envelope and if the information in the letter is not using data standards, it is still proprietary. Right now the hot thing is "FHIR." It is merely a resource locater - i.e., it 'webizes' access to supposed data resources, but again, that data is in proprietary format.
They are now building a 'stack' to support FHIR and HL7 is on board....and yet, the data is still not in a standard format (except for public health reporting). I just got back from a client visit - all of their clinical information system interfaces are using a pdf transfer.....and the data in the flow sheets is in ****** vendor proprietary format.
In the end, the acquirers are going to need to demand that things become interoperable and usable. While I do believe that using computers in general can make many things better, in the case of EMR/EHRs and clinical workflow it has been proven by research the clinicians have gotten the shaft in much of the implementations. And it is not just the older clinicians that are complaining...it is the younger ones, too.
The Health IT industry has a lot to answer for on this. Interestingly, I was on a group evaluating proposals for US funding of Health IT projects and it turned out one of the other people in the group was the CEO for HL7. I made a few derogatory comments regarding the medical device aspect of the FHIR and HL7 standards and he agreed. So, it's a known problem and a huge barrier to true interoperability.
What I find very sad is the people telling the clinicians to just "snap out of it." I had a similar experience when I was working for a very large healthcare organization - the IT people kept telling us and the clinicians to 'snap out of it' and just do what they wanted when they wanted it. Turns out the IT people had never visited an ICU or clinic and didn't understand how disabling the introduction of their particular technology would be to the delivery of healthcare. I was constructive and set up a 'walk-through' for the IT people and jokingly asked the nurse to make sure a patient crumped, had a code with a crash cart needed and some blood thrown around for extra drama. To be fair, the IT people came away with a much better understanding and were much more amenable after that.
