There's rampant corruption in healthcare, even after the Sunshine act passed into law in 2010.
Common methods include: - Paid "speeches" - Paid surveys - "Training/Education" retreats at swanky resorts
Also look into Outcome Health, a newly minted "unicorn" based out of Chicago. Their marketing spin is about how their mission is to help patients receive the most optimal treatments and "outcomes", but in reality the whole business model is based on installing "free" tv screens and tablets in physicians' offices and then pushing ads. Im sure there are kickbacks involved with the individual physicians. There was a WSJ expose about it a couple of weeks ago (http://archive.is/QZnTN).
