The problem lies with the fact that it goes on your medical record, which, for all intents and purposes, is public record. Hippa laws are a joke here in the good ol’ USA. Your insurance company sees it.
I never hear or read about any such complaints in the country where I live, nor in other (western) EU countries. Medical records are NOT public record here and I would not like to be charged with violating them.
And yet, our medical records are on-line, in the sense that medical personnel (at hospitals or emergency services for instance) can immediately get pertinent medical information on a patient, be it a new patient or one they have had for years. My family doctor can instantly access tests done by specialists and the other way around. When I go to a new doctor/specialist, I no longer have to go through the litany of telling about a past operation or which prescription drug I am now taking, even if I forget the name (which I do). It is all in my medical records.
Nor are our medical records 'government-controlled' as the more paranoid believers would wish to think. They are administered through what are called 'mutualities' who act as intermediaries between patients and the Ministry of Health. These are non-profit institutions, usually having historically grown from political affiliation. Meaning there are Christian Democrat mutualities, Socialist, Conservative etc ...
And neither does one hear of big breaches of security and so on. Employers are not allowed access to medical records, period. If they should ever use these from illegal sources, well, I wish them a long and boring prison stay or a draining of their bank accounts and assets and preferably both.
It seems there is always a huge breach or a massive security leak going on in the US. Sometimes i have to wonder how much of that is just sensationalist reporting gone overboard in order to keep people scared and docile and secretive and scared.
