We're going to be letting big data and whatnot into health. Every heartbeat you have, every milliliter of blood drawn, even your base pairs will be cataloged meticulously and shoved into a database. So, that amount of privacy/care is gone, never to return.
There are two things that are really worth asking:
Are patients or practitioners the ones who own collected data?
What is the utility of data leaks of non-billing information, truly?
For the first, I rather think we're doomed if we don't legislate that patients own all of their own data and license it back to care providers--basically, treat labwork and everything as works-for-hire with copyright belonging to the patient.
For the second, I think we're going to continue to treat all the health data as super mission critical, which will in turn only cause "security contsultants" to line their pockets further and justify the miserable busybodies in hospital IT that get in the way of progress under claims of "but but but the terror^H^H^H^H^HHIPAA".
We already give away gigabytes of data every year about everything else, so it's kind of silly/sad that we're so protective about arguably the least harmful/most useful data we have.
