Who wants a medical test unless it is absolutely necessary, would any doctor order a test just to placate a patient (or make money), would a patient ask for a specific prescription drug because they saw it advertised on television? Of course not you say, well the truth is that up to 30% of all health care is unnecessary and all of the above things do happen.
Now the question is why. Fear of being sued comes to mind, but it is more than that. Americans have become conditioned to think more is always better and coupled with near total insulation from the cost, hey why not another MRI…just to be sure. There is the array of technology at our disposal, somebody paid for it and it has to be used, the more we have the more we use. But it is even more than that. When you have an MRI or a scan or some other test, the chances are they will find something. Often that something is not significant and without the test you would live with it without further incident not even knowing it exists, but now that you do know it is there, well now you may end up in the system and more care is prescribed.
We know we have a problem with over utilization and now we are adding thirty million more people to the covered insurance roles with the increased demand that goes along with it, and you think we are going to control health care costs.
