I'm familiar with the argument that since medical malpractice liability represents such a small portion of total U.S. healthcare spending, tort reform isn't likely to make much difference. I don't recall having previously heard it claimed that it would actually increase costs, but I'd be interesting in seeing the supporting arguments.Funny, tort reform is the first thing they always bring up. Of course, tort reform will increase the cost of healthcare, but who's paying attention to insignificant details like that?
