Are most emergency room visits really unnecessary? - By Zachary F. Meisel and Jesse M. Pines - Slate Magazine The left is always trying to argue that we waste so much money going to the ER and that health care reform is going to change all that. But let's look at the actual numbers shall we? ER care is less than %3 of health care spending Of that %3, only %12 is what would be considered non-urgent. So let's stop pretending that passing Obamacare is going to cut costs by eliminating wasteful ER spending. That wont put a dent in it. That isnt the problem.
