Even when you remove litigation as a factor, the extent of tests and procedures that are ordered do not change. Enacting "tort reform" will continue to fail as a solution to this country's health care problems.

Medical-legal reform received only lip-service during the Federal health care legislative process in the spring of 2010 -- drastically disregarded as fundamental contributors to high health care costs.
