Electronic medical records will be the end of any medical privacy.
I don't see why that would be the case.
In Belgium, we all have electronic medical records that can be accessed by accredited doctors or hospital staff. Obviously this saves a lot of time and effort, makes going to a different doctor far less of a hassle because you needn't bring along any files, doctors can simply access everything right on the spot. No more needing to try and explain your old problems either and also no more forgetting to tell things. This also avoids a lot of double testing (but then also prevents possible ways of earning fees for testing).
Naturally a stringent set of laws governing access and use of those records is essential to maintaining privacy and keeping the info strictly within professional, medical bounds. And this seems to not be a problem here. There is no epidemic, small scale or large, no particular sandals surrounding electronic medical records. Strict laws will in the main prohibit misuse.
Also consider that medical care is government-run and overseen. We do not have large (or small), private, corporate medical insurance companies providing health-care. That alone helps in avoiding the risk of misuse. Why?: because the pursuit of profit encourages misuse because the temptation ends up becoming to great to find a way of walking the razor's edge and trying to turn that knowledge into an advantage financially. Especially when backed up in a corporate situation.
Perhaps folks in the US should be concerned after all, because it seems like so much of everything is governed by the insatiable drive to generate profit. The whole mind set is geared to that end and therefore people cannot believe it can be done in another manner.
