Unfortunately, there are some bad apple physicians who are very aware of the power they wield and if they feel something needs improvement, they will be extremely vocal... Sometimes at the detriment of the truth.
I've been subject to the spread of misinformation by a couple of physicians related to some past projects, and it's not pretty. All you can do is try to re-educate these same physicians who are misunderstanding some facts, and as you can imagine, it's an uphill battle.
I would make the effort to understand both sides of the coin before assuming these "big, bad" hospitals are in the wrong. As they say, the truth is often somewhere in the middle.
