Sir, I write to you concerning my alarm that, in the twenty-first century, it would appear that some of your correspondents can provide controversial lines of therapy for their patients without obtaining informed consent from their patients. If the practitioner, whom some may think has a monopoly of information, cannot provide an evidence base for such proposed procedures, it would therefore follow that the patient cannot make an informed decision therefrom. The burden for informing the patient lies with the practitioner; the patient has no burden to enquire.
