Cancellation of a doctor’s license in USA

In the United States it is common for a hospital to refuse to treat a critically ill patient if they are not insured or are not US citizens. In Europe such a concept is considered ancient and uncivilised. In the US, doctors sometimes refuse to treat or prescribe the right options to a patient if the doctor’s religious beliefs go against what is medically best for the patient. It happens most often in cases of abortion, birth control and treating homosexuals where the doctors’ medical ethics conflict with their religious beliefs. Such an act in Europe would lead to cancellation of a doctor’s license to practice for violation of the Hippocratic Oath.
