Watch a lot of television, eh?.
"People" turn into "patients" when they get sick. That means they are already "coming to harm".
Sometimes, the harm can be ameliorated because of what we do. On occasion, it can be eliminated entirely.
However, on occasion, harm continues to the endpoint of a bad outcome, or death, despite what we do. Also, on occasion, our interventions into an unstable and confusing situation makes it worse.
Who on earth would work in this environment under threat of criminal prosecution? You? The doctors on "ER"?
Not me, pal. If you ever get this passed, best of luck when you're sick.
If malpractice is found, the responsible parties should be liable for all reimbursement costs required to fix the problem. If more punishment is desired then malpractice should be criminalzed and the offender(s) sent to prison.
Of course, the trial lawyers would hate this since they are uninterested in justice. All they want is the big fees. Criminaliztion would eliminate those.
