  Best interests in early Prolonged Disorders of Consciousness: different balances

  • John A Gorst, Consultant Intensivist Morriston Hospital, Swansea

  Professor Wade’s article is an excellent overview of how to apply best interests to decision making in prolonged Disorders of Consciousness (PDoC) and should be mandatory reading for all health professionals caring for individuals with brain injuries1. However it fails, as does the Royal College of Physicians PDoC guidance, to adequately emphasise the vastly different balances when comparing withdrawal or withholding of clinically assisted artificial nutrition and hydration versus far more invasive and burdensome treatments.

  A significant proportion of patients in a PDOC are only alive because they were subjected to the very invasive life sustaining treatment that modern medicine can inflict. The existence of the clinical entity of PDoC could arguably be seen as a failure of prognostication and best interests decisions during the acute phase of a catastrophic brain injury; continuing invasive treatment that is arguably either ‘futile’, not in the patients best interests or be so invasive and prolonged to be disproportionate to the likely outcome2. However prognostication can be a difficult and uncertain at this stage.

  In our institution we admit up to 70 patients per annum who have sustained an out of hospital cardiac arrest and the majority of these survive long enough to need to assessment of neurological prognosis. At 72 hours, if the patient remain neurologically obtunded, we use multi-modal assessment to assess the likely outcome according to internation...

  In our institution we admit up to 70 patients per annum who have sustained an out of hospital cardiac arrest and the majority of these survive long enough to need to assessment of neurological prognosis. At 72 hours, if the patient remain neurologically obtunded, we use multi-modal assessment to assess the likely outcome according to international guidelines3.

  If a poor outcome (death or severe neurological disability including PDoC) is deemed likely or very likely best interests meetings are held. We then, after appropriate consultation, consider withdrawal of life sustaining treatment which, at this stage, is mainly in the form of mechanical ventilation.

  Often families take some time to become reconciled to the sad reality that modern medicine can not return all patients to a life they would wish for. However when there is a prolonged disagreement as to whether Intensive Care is indeed in the patients best interests the patient has entered the realms of a PDoC.

  Recent CoP proceedings4 in such a case led to application by the neuro-rehabilitation and legal fraternity, wrongly in my opinion, of the Royal College of Physicians PDoC guidelines to a patient on Intensive Care. Is it ever in a patients best interests, unless previously expressly stated, to subject them to many months of Intensive Care when the assessed best outcome by experts is a PDoC? Is this proportionate? Is this appropriate use of finite healthcare resources?

  As seems to be ever common, arguments then ensue about honing in on the exact diagnosis between MCS and VS using assessments that are not necessarily applicable to a patient in Intensive Care. To an Intensive Care clinician these discussions are irrelevant especially when the patients physical status is so fragile it is unlikely to support any potential recovery. Sadly, rigid application of the guidelines can lead to an inability to look holistically at the whole individual and focus solely on the issue of the brain and PDoC ignoring how physical health impacts on the overall prognosis.

  It would seem disproportionate to need the same certainty of diagnosis and prognosis, i.e. many months of PDoC diagnostic assessment, to withdraw highly invasive intensive care compared with withdrawal of CANH in a ‘stable’ patient. Sadly, such subtleties are not explicit in the current PDoC guidelines sometimes resulting in these very authoritative guidelines over-ruling common sense and holistic care.

  Caveats in the management of prolonged disorders of consciousness

  Dear Editor,

  We would like to congratulate Dr Derick T Wade on the article advocating a formalised approach to best interest meetings for people suffering from prolonged disorders of consciousness (1). It is a bold and pragmatic approach, borne out of his extensive experience, which will undoubtedly be of use to the practicing clinicians in the concerned jurisdiction. We are writing to supplement it with a few points which we consider worthy of additional noting.

  Firstly, we are glad of the title using the term “prolonged disorder of consciousness” given that persistent vegetative state (PVS) and minimally conscious state (MCS) are problematic from phenomenological and practical points of view. As Dr Wade notes, the two are difficult to differentiate and in practice permanence takes significant and possibly indeterminate time to establish. Unfortunately, the Law maintains a distinction between the two founded in the leading case of Anthony Bland. Abolishing the distinction would in practice prevent splitting hairs over what is likely to be an equally tragic outcome for the individual concerned, and the surviving relatives. From a legal and philosophical point of view, it can be argued, as it was in the Bland case, that patients in PVS lack any “best interests”. To quote Lord Mustill – “The distressing truth which must not be shirked, is that the proposed conduct is not in the best interests of Anthony Bland, for he has no best interests of any kind” – ackno...

  Dear Editor,

  We would like to congratulate Dr Derick T Wade on the article advocating a formalised approach to best interest meetings for people suffering from prolonged disorders of consciousness (1).

As Dr Wade notes, the two are difficult to differentiate and in practice permanence takes significant and possibly indeterminate time to establish. Unfortunately, the Law maintains a distinction between the two founded in the leading case of Anthony Bland. Abolishing the distinction would in practice prevent splitting hairs over what is likely to be an equally tragic outcome for the individual concerned, and the surviving relatives. From a legal and philosophical point of view, it can be argued, as it was in the Bland case, that patients in PVS lack any “best interests”. To quote Lord Mustill – “The distressing truth which must not be shirked, is that the proposed conduct is not in the best interests of Anthony Bland, for he has no best interests of any kind” – acknowledging the profound nature of the damage he suffered leading to absence of any cognitive process (2). In contrast, those in MCS, require a balancing approach to establish their best interests which may lead to a different decision concerning withdrawal of CANH (3). A patient’s ascertainable wishes are determinative in the decision-making as recognised by Charles J in Briggs v The Walton Centre NHS Trust & Another, who, notably, framed his decision in terms of consent / refusal and stated– “I have concluded that as I am sure that if Mr Briggs had been sitting in my chair and heard all the evidence and argument he would, in exercise of his right of self-determination, not have consented to further CANH treatment that his best interests are best promoted by the court not giving that consent on his behalf.” (4)

  Secondly, Dr Wade also hints at the dual obligation faced by the clinicians looking after patients with disorders of consciousness, where an obligation towards the family and society at large is also apparent. These obligations are however suppressed by the perceived professional obligation to protect life as laid out by the General Medical Council. The conflict of duties is a fundamental critique of deontological approach to ethics and thus a perennial problem of bioethics and healthcare ethics where utilitarian considerations emerge. However the law not only makes it clear that prolongation of life may not be the best option for the patient but also that healthcare has to be rationed at many levels.

  Finally, while second opinion is invaluable in life or death decisions, and strongly supported by the recent case law (5), consideration may also be given to review and adjudication by ethics committees, something we feel is underused in the UK in spite of growing complexity of ethical and legal problems associated with healthcare.
