The doctors interviewed said the computer program would have a pop-up screen advising them to admit a patient. They had to override it. Clearly hospitals are going to make more money if they admit people who don't need to be admitted. They "quota" was somewhere around 20% of the patients seen should be admitted.
If you want to know why health care costs so much in this country, consider this, it's estimated that $210 billion a year -- about 10 percent of all health expenditures -- goes towards unnecessary tests and treatments and a big chunk of that comes right out of the pockets of American taxpayers in the form of Medicare and Medicaid payments.
