I recently produced a film, called "Money-Driven Medicine," based on the book of the same name by Maggie Mahar, which looks at the way that our business model for medicine has badly damaged the patient doctor relationship.
"But this isn't just a waste of money. This is hazardous waste - waste that is hazardous to our health," says Mahar, a healthcare fellow at the Century Foundation where she writes the healthbeat blog.
"When a patient is subjected to an ineffective treatment he is, by definition exposed to risk without benefit. We need to squeeze this waste out of the system. If we do, we have enough money to provide high quality, affordable and sustainable care for everyone."
