Well it *might* be true that healthcare data mining could save many lives. That's an educated guess - that large enough sample sets would let researchers discover correlation and causation effects that we have never noticed, and they can do this using machine learning algorithms, or just the nature of enough data to actually show trends.
But yes, for travellers and for the US you need to worry about what insurance companies are going to do with that data, and if they're going to improperly use that data to deny you care you paid for, or if it makes it impossible to get healthcare coverage based on data.
Unfortunately there's no easy way to make medical data privacy irrelevant. Even in places where you cannot be denied coverage regardless of your medical history (say the NHS, where even if you break into NHS hospitals and steal stuff all the time they still cannot deny you entry for care) you still don't necessarily want your neighbour to be able to discover that you where hospitalized for having a dildo stuck up your ass.
