I think one of the most aggravating things about interacting with the health care system is losing control of cost/risk/reward tradeoffs. The mandatory transfer and ambulance ride in the linked story are an excellent example. I think I'd have walked out against medical advice in that circumstance, but there is the constant danger of being subjected to similar costs, both monetary and physical, when I am less conscious or at a serious informational disadvantage. The need to bring a patient advocate with you to the hospital whose role echoes both doctor and lawyer is becoming quite serious.
