The benficiaries of interoperability are patients, and yet we still haven't given them a way to communicate how to get their data. This is where the notion of social interoperability comes in. It's your data, ask for it is a short commercial I wrote a script for back in 2010. The idea behind it was that we need to educate patients about how to ask for their records in a way that everyone, patients, providers, and vendors understands. What they mean is give me my CCD and/or CCDA, but we geeks don't really need for everyone to understand that's the secret sauce.
It's what marketers would probably call a brand awareness problem. What is the brand for patient engagement? Is it CCD/CCDA? BlueButton? BlueButtonPlus? VDTNow? Meaningful Use? None of the above? We need to agree on, and communicate that to patients and consumers, and then we need to educate vendors and providers what that means.
Social Interoperability, the ability to communicate with normal human beings, will create the demand for and use of technical interoperability. And that will get us all where we want to be. After all, it isn't just providers we want to be meaningful users of data and technology, it's for patients too.
