The way I look at it "I" am the most important member of my medical team, after all I'm the one who endures the benefits or consequences of any decision "we" make - and "I" have the final say.
Since I am paying the bill, whether thru insurance or out of pocket is immaterial, I'm still the one paying the bill, "I" am therefore the employER and "they", like it or not, are MY employEE. Since they, supposedly, have the education and knowledge, THAT is what I am paying them for. They make suggestions based on their knowledge and experience, "I" decide whether to follow their suggestion - or not - since I am the one who benefits or suffers the consequences. It is THEIR job to see to it that I am FULLY INFORMED to the best of their ability. If that isn't good enough then I need a different doctor. If it doesn't make sense to me then it doesn't get done.
My computer says I need to upgrade my brain to be compatible with its new software.
