"More than half admitted describing someone’s prognosis in a way they knew was too rosy. Nearly 20 percent said they hadn’t fully disclosed a medical mistake for fear of being sued. And 1 in 10 of those surveyed said they’d told a patient something that wasn’t true in the past year."
As a trial lawyer, I'm not surprised that this many doctors are cutting corners with the truth and/or outright lying to their patients about deadly mistakes. I would wager that, among the 5% of doctors who commit the most malpractice, the percentage is much higher.
