when you say "right". I think you mean "duty." Of course, very few do. Patients also have the "right" to call out doctors who are not mentally fit to practice surgery or who are incompetent. WSJ is writing about this very subject. A doctor can turn away a patient for ANY REASON. We are talking about doctors who accuse patients of mental illness AFTER performing surgery on them.
Thank you for clarifying. I wasn't aware that the discussion pertained to a patient's dissatisfaction after surgery and then the doctor claiming the patient is mentally unstable.
