I come from a land where healthcare is self regulated. In essence the government has determined what health care professions should be regulated, they set up templates for all healthcare to follow and provide guidelines over time. In essence this allows each profession to determine what education one needs to practice. It forces each profession to self police to a certain extent, should they fail to do so, the government can and has stepped in to remove the privilege. For some things the government has set clear policies that all professions must follow. For example zero tolerance on sexual abuse.
For the most part this system seems to work. Yes there is some protectionism, more so in some fields than others. Self policing has helped some from exposing their dirty laundry, but the press has been active in clearing the air and policies.
The things I am most flabbergasted with is the potential for conflict of interest and informed consent. It is interesting that a foreign corporation can set up or buy their own clinics to self promote their own products. I feel that informed consent should go beyond a pamphlet that describes what each model lets you hear better. “Here you go, this is what we suggest, pick one and we will set you up” lacks of informed consent.
