list of routine practices and they say they are wasteful and profit-driven including x-rays and ekgs an antibiotics, and as a patient, you want the stuff, but are you guys prescribing too much? >> first of all, yes. we have 30% more tests than we need to be ordering in treatment and this is called choosing wisely and comes from the american board of internal medicine, my board and actually "consumer reports" and putting together analysts in all specialties to decide whether the tests are overdone. on the surface it is a great idea and the problem comes in in actually doing it. i look over the tests in the american college of physicians, which i belong to and i don't agree with a lot of this. they say no routine chest x-ray before surgery, sometimes you go on a respirator you might need one and ekg for a regular visit, i like a baseline and back page, no imaging studies and that may be true, but, eric, we're in a world of liability and malpractice.
