Montgomery and the Information needed for Valid Informed Consent


In the light of Montgomery case  the Royal College of Surgeons  has warned the NHS that failure to fully implement informed consent rules opens the way to more litigation. In this case the court held that doctors must ensure patients are fully aware of any and all risks that an individual patient, not mainstream medical practice, might consider significant. This judgement appears contrary to the judgement given in the Bolam case which held the information necessary for consent to be considered valid was the information most doctors would consider necessary. In other words, the medical profession could act in a paternalistic manner with regard to the amount of information it provided.

I have some sympathy for the Montgomery decision because I believe that patients rather than their doctors should decide how much information they need to make informed consent decisions. Nonetheless I also believe there is now a clear danger of some patients being over informed making it hard for them make informed consent decisions. There is a difference between doctors simply acting paternalistically and acting paternalisticlly if asked to do so. In this posting I will argue it is possible to over inform some patients and that it is possible to give adequate consent on limited information.

 In making by argument I will use an example provided by Steve Clarke.

“Consider the case of ‘Squeamish John’. Squeamish John cannot bear to hear the details of medical procedures; hearing these make him feel weak at the knees and dramatically diminishes his capacity to make sensible decisions. Nevertheless he does not wish to abrogate responsibility for his decision about whether or not to undergo an operation. Squeamish John wishes to participate in a restricted informed consent process in order to make his decision. He wishes to make a decision based only on the disclosure of the risks and benefits of the operation couched in cold, impersonal, statistical language. He does not wish to have any significant details of the procedure described to him.” (1).

In addition, let us assume John is lying in hospital bed suffering from type2 diabetes and needing a leg amputation. Let us assume John gives consent in the restricted way outlined by Clarke and he regains consciousness minus one leg. Intuitively such a situation seems very wrong. Nonetheless I would argue it is possible for John to make an autonomous decision based on restricted information. John is making a decision to trust his doctor and it is possible to make an autonomous decision based solely on trusting the advice of another. If I trust the advice of my lawyer or financial advisor I am making an autonomous decision I can identify myself with. Are then doctors any less trustworthy than lawyers or financial advisors? It seems obvious to me that they are not. Does then the context in which informed consent takes place differ from other contexts such as the law and finance in respect of an agent’s ability to make autonomous decisions? Once again I would suggest it does not. It follows if squeamish John is permitted to make a decision in the way he prefers it would be an autonomous decision.

However, let us put questions of autonomy to one side. Let us assume John’s doctors follow the Royal College of Surgeons advice and do not allow him make his informed decision based on restricted information. Let us further assume John refuses to listen to or read most of the information they provide. In this situation it seems to me that John’s doctors have two available options. First, they might discharge him simply because he won’t listen knowing that his discharge will probably lead to death. In less life threatening cases than that of John this would be the probable outcome. It seems wrong to condemn summon to die because he simply won’t listen. Secondly they might decide his refusal to listen to all the details of his projected operation makes him incompetent to give consent. This decision would have to be validated by the courts. Let us assume this decision is validated and a decision on John’s treatment is made by a surrogate. This surrogate should make a decision based on John’s best interests, his best interests will be decided by his doctors. The outcome would be identical to that if it was accepted that John could make a valid informed consent decision based on trusting his doctors.

I accept my example is an extreme one but I believe it nonetheless raises some interesting questions. First, the Montgomery case seems to show that informed consent is not simply based on respect for autonomy. I have argued it is perfectly possible to make an autonomous decision based on trusting the advice of another person. Some patients at a very stressful time might want to make extremely complicated decisions and would prefer to make simple autonomous decisions. The Montgomery decision seems to deny them the possibility of making such decisions. The Montgomery judgement seems to require that much more information needs to be provided in order to make a valid informed consent decision as opposed to an autonomous decision. Secondly if doctors must ensure that patients are fully aware of any and all risks involved in their procedure, must doctors ensure they understand these risks including the probabilities involved or only have the capacity to understand. Must doctors ensure that their patients listen intently or fully read the information provided? Lastly even if doctors can be sure that patients understand the information should they also insist patients actually use it when making decisions? In conclusion I believe there are problems connected to the Montgomery case’s requirement that patients must aware of any and all risks involved their procedures. I also believe patients must have the possibility of becoming aware of any and all risks involved their procedures but that this awareness should be driven by patients’ needs. It seems this awareness is at moment being driven by fear of litigation rather than any genuine concern for patients’ real needs.
