It actually seems like an interesting bit of phrasing.
I think the ad, and you, are talking about malpractice insurance and other documentation to prove that you didn’t do malpractice.
The comment you replied to is actually taking about the underlying act of malpractice.
The first line of defenses against actual malpractice is that professionals are supposed to have some self-respect and standards. But of course our society is structured against professionalism. The insurance company or hospital admin doesn’t care if you are a real professional who does the right things when nobody is looking, that’s too hard quantify.
The ad is offering the opportunity to be a professional.
What happens in other countries when the doctor amputates the wrong leg or operates on the wrong patient? Does the government pay damages arising from malpractice?
In short: in some, yes. In my country, one's private insurance company may pay damages for injuries caused by medical malpractice. This may be included in the home insurance or some health/injury/accident insurance. Otherwise and in addition, you are covered by the provider's malpractice insurance. Private medical providers must have malpractice insurance. There is also a national scheme, regulated by law, that covers all public providers, which in practice would be all the emergency departments etc.
They are. Those $10M+ lawsuit verdicts get paid one way or another, and everyone is doing unnecessary cover your ass work to be able to not be in the line of fire for that lawsuit.
