Yes. Malpractice insurance isn't super costly, but knowing many doctors (my father was a doctor as well), the adversarial relationship that malpractice suits sets up is a heavy burden. We know that overtreatment is a huge source of the cost overages we have in the US relative to other countries with the same health outcomes, and malpractice threats are a significant contributor to that, although it is obviously very hard to measure.
Personally, I think there could be some advantages in making a more patient-responsible system. The most expensive healthcare we have is ongoing (chronic) stuff, and most people with issues like that end up being experts on their own conditions. Why not allow them to get their own medicine and equipment directly rather than be forced to visit the doctor every N weeks to refill a prescription? Or be severely inconvenienced by being somewhere where it is difficult to obtain the right prescription for the medication they know, any sensible person knows, they need? That's silly and inefficient.
