Re: New rules of consent: the patient decides

The Medical Defence Union recently stated that clinicians may have a defence against a claim of clinical negligence if they were to act in a way they felt 'was not in the patient’s interests.' (1) This suggestion was contestable when it was made, but the recent Supreme Court decision in Montgomery v Lanarkshire, as reported in your pages (2,3,4), now makes it a very flimsy defence indeed.

Although clinicians have an ethical and professional duty to act in their patients' interests (5, 6) the law only recognises acting in a patient's 'best interests' in the context of a lack of mental capacity in accordance with the Mental Capacity Act 2005. In patients who have capacity, acting in their 'interests' has no justification in law as it represents medical paternalism.

This was exemplified in Montgomery wherein the defendant did not disclose a risk of shoulder dystocia as she was of the opinion that to do so would promote women to request Caesarean sections 'and it's not in the maternal interests for women to have caesarean sections.' (7). This approach was previously supported by the majority decision in Sidaway (8) but it has been under increasing strain with more recent rulings favouring the rights of patients to be informed of risks(9,10,11). The Montgomery ruling has unequivocally overturned Sidaway with the patient's right to be informed about risk now paramount; and it is the patient, not the doctor, who determines what she needs to be told. This is the case even if such information would result in the patient making 'a choice which the doctor considers to be contrary to her best interests.' (12) The law is now framed that the overriding 'interest' is the patient's right to autonomy - anything less is negligent. (13)
