Speak for yourself. I for one trust healthcare professionals to do their best for my health unless they prove to me personally that they are incompetent. I don't consider NHS workers saintly or flawless - I wouldn't, for instance, accept a lift home from the guy in the pub just because he's a doctor, or lend £50 to a stranger just because they're a nurse - but on a professional level, I trust them to do what is best for me in any given situation. Don't try and transpose your own insecurity and paranoia onto the whole of society.
