Doctors and hospitals have self interest. The American Medical association has self interest. The interest isn’t always the best interest of their patients. It’s more money in their pockets. According to a study called Courage, stent procedures did not always extend life, decrease heart attacks or improve cardiac conditions. They do, however add $900 to the bottom line of physicians performing the procedures at a cost of 15,000 to the patient and insurance companies. Consumers hear about the procedure and ask for it by name. Doctors with the ability to increase their income won’t say no. Insurance companies aren’t going to fight the recommendation, they’ll just increase rates for everyone including you and me.
