We have had an overwhelming response for our invitation to participate in this new series from clinical ethics committees from all over the UK, and look forward to some lively case discussion. Committees which would like to participate but which have not already submitted a case should contact Ainsley Newson (ainsley.newson{at}bristol.ac.uk).
Cardiff and Vale NHS Trust Clinical Ethics Committee (CVCEC) agreed to discuss this case. CVCEC has been in existence, initially in shadow form, for four years but was officially launched in May 2005, the first in Wales. There are currently 25 members, including medical, nursing and other professionals from within the Trust, augmented by two professional ethicists, a chaplain, a non-executive member of the Trust Board, a member of the corporate management team and two patient representatives. The CVCEC meets every month and discusses individual cases as well as reviewing when requested, various policies and procedures from an ethical viewpoint. Observers are welcomed to the meetings by arrangement. CVCEC has organized three very successful annual conferences and tries to raise the profile of clinical ethics by contributing to The Grand Round at intervals. A report is presented to the Trust Board and to the Clinical Governance Committee annually.

Mrs D, a 75-year-old retired librarian, was fully independent until four weeks ago. She lives alone and cares for herself, going out to the local shops on a daily basis. Over the last four weeks she has become increasingly tired and lethargic. She has not been eating well and has lost weight, though she is not sure how much. She saw her general practitioner (GP) who could find no specific cause for her tiredness but he sent off some urgent blood tests. The following day she saw her GP again, the tests revealed severe kidney failure and she was sent straight to A&E.
On arrival in A&E she was seen and assessed by our general medical team. She was tired and listless. There were no significant positive findings on clinical examination. Repeat blood tests confirmed severe acute kidney failure with functions less than 10% of normal. Her potassium level was high though not immediately life-threatening. Our team judged that immediate treatment with dialysis was not needed, but that it would become necessary within 24–72 hours.
An emergency renal tract ultrasound has shown that the drainage system of both kidneys is expanded (hydronephrosis) suggesting that the urine drainage system is blocked. A mass in the pelvis is also seen which could account for the blockage. This has been confirmed by computerized tomography (CT) scan, and the radiologists feel that from its irregular appearance it is almost certainly a malignant tumour. Identifying the precise origin of the mass from the CT scan is difficult – it is possibly ovarian or uterine.
The options available to the patient and the team include the following:
Mrs D's wishes and her relatives' views
The patient's closest relatives are her sister and nephew: both have attended with her. She has no other close relatives. They have confirmed that she is normally alert and oriented and agreed that this was still the case.
Our discussions with the patient have proved difficult. She is tired and easily distracted, though not overtly confused. She is reluctant to be drawn into discussions about her management, stating that she would prefer the doctors take decisions for her. She has said: I'll do whatever you think necessary, doctor, while at the same time saying that she is reluctant to have any procedures, although she has already allowed the insertion of an internal jugular line. The stress of her condition, the biochemical changes (uraemia) and the sudden change of context are all undoubtedly affecting her mood and outlook. Nevertheless, we have no grounds to suspect that she is not competent to make decisions about her treatment but she appears disinclined to do so.
Both the family members feel that she should not have unnecessary invasive procedures. They think that, assuming a reasonably high level of confidence that this is an untreatable pelvic malignancy, dialysis is not appropriate. They are less decided about nephrostomies. In general, they feel that interventions to simply prolong life in the absence of possible cure and with the possibility of worsening symptoms from the malignancy (such as pain) are not warranted. Both have stated these views clearly and independently and give the impression that this represents what the patient would want. We explained that the risk of worsening symptoms would have to be weighed against the possible benefits of the patient having several months to come to terms with her diagnosis and prepare to die. The alternative, not intervening, would mean that death was inevitable within a few days.
Our reason for referral to Clinical Ethics Committee
The team has approached the Clinical Ethics Committee to discuss the case, with the following questions in mind:
| Response from CVCEC |

Question 1: The patient is competent but choosing not to enter into decision-making: Does the decision then become as if the patient were incompetent? If so, what weight should be given to the relatives' opinions?
We accept that under the Mental Capacity Act 2005, there should be an assumption that the patient is competent until proven otherwise and we accept that we have not spoken to Mrs D or had an opportunity to assess her so have to rely on your judgement and impressions. At the same time, given her clinical condition, we wondered whether she had only fluctuating capacity or capacity to make only some kinds of decisions. Accordingly, we wondered whether more should be done to enhance her capacity – for instance, even a couple of sessions on dialysis would enable her to be more alert, and as a result she may be more willing to engage in decision-making about her care and the future management of her condition. The Mental Capacity Act certainly puts the onus on carers to do everything possible to enable patients to make decisions for themselves. We completely accept that patients are, and should be, free to decide to let those managing their care make decisions for them. Indeed, it would be arguably paternalistic to force such patients to make decisions for themselves if their autonomous wish is for these decisions to be made by others, whom they trust to act in their best interests.
In this case, however, we were uncertain, on strength of the information provided, whether Mrs D was as able as she could be to make the decision to let her doctors decide for her. We wondered whether there would be some merit to providing minimal treatment aimed at enhancing her capacity and enabling the team to become much clearer about what, precisely, her wishes are. For instance, although it could very well be the case that she simply trusts her doctors to decide for her (which is not unexpected in a woman of her age), it might also be that she is scared, or perceives herself (wrongly) to be a burden, or is overwhelmed by her (potentially terminal) differential diagnosis and the speed at which she has deteriorated from being very independent to quite poorly, and possibly, imminently dying. Also, minimal treatment to enhance her capacity might take some of the urgency out of the situation and permit other mechanisms to be put in place that would provide more information to the team about her wishes. For instance, she could be offered the services of an advocate (in our experience Independent Mental Capacity Advocates [IMCAs] are very reluctant to become involved at all where relatives are available, so this is probably not a realistic possibility in Mrs D's case, but an independent advocate may be) and a clinical psychologist. She might find it easier to confide in an independent advocate than her sister and nephew, and a clinical psychologist may be able to provide the team with more information about her reasons for apparently not engaging with them. This further information may be of use in addressing your other two questions. It would also enable you to be confident that she has understood and taken on board all of the information about the seriousness of her condition and consequences of the various options you outlined.
On the other hand, it may be thought that to provide even such minimal treatment is to make a commitment to continue to treat her, even if she is adamant that you must decide for her, and this might not be something that you feel comfortable with. Indeed, she may not feel able to tell you to stop treating her, even if she finds the treatment undesirable, as patients sometimes feel that they are letting staff down if they subsequently refuse treatment. Moreover, we recognize that even minor interventions to improve Mrs D's capacity in the short term might have a longer-term impact on her quality of life and, as such, will necessitate a balancing of benefits and harms. For these reasons, it is important that the purpose of this minimal intervention is made clear to the patient, relatives and the team, so that everyone is aware that all that is being offered is the opportunity to become clearer about what her views actually are.
We also discussed whether, under the circumstances you described, Mrs D has effectively given her implied consent to whatever course of action you think best because she has consented to leave the decision-making to you (one member thought her consent could even be described as explicit consent, but others disagreed with this analysis). This led us to discuss how best to summarize the ethical tensions the case presented. We were uncertain whether you regarded this case as one of justified, albeit weak, paternalism1 (because Mrs D was on the border for capacity and you were acting in her interests) or a classic case of beneficence versus non-maleficence (because however you acted some good and some harms may result and a tension results from attempting to balance the two). We were ourselves uncertain of how to categorize this case. On balance, though, we were not convinced that, given her condition and on the strength of the information provided, you could be certain about her capacity and enhancing her decision-making powers would help to give you more certainty and perhaps provide a solution to your questions.
Turning to the role of the relatives, clearly they are in a position to help you to understand what Mrs D's preferences are likely to be, though in our experience it is rare for patients to have had such explicit discussion with relatives, especially when their condition has such an acute onset. It may, however, be that she has talked to them about other people with (perhaps different) terminal conditions and expressed some opinions about what she would have wanted for herself in their condition that could be applied to her current circumstances. Her relatives certainly appear to be, independently, agreeing that conservative management is consistent with her character. If you do decide to undertake minimal interventions to enhance her capacity, we offer the obvious advice that this should be explained to the relatives so that they share your understanding of the nature and purpose of this treatment. We also noted that Mrs D seems to have expressly requested that it is the doctors and not her relatives who should decide what to do.
On balance, the consensus in the group was to advise the team to offer as minimally invasive treatment as possible to enhance Mrs D's capacity. We did discuss the various treatment options available to Mrs D and of these which would represent the best balance of maximizing capacity while minimizing discomfort or risk, yet we were uncertain of whether two or three sessions of dialysis or the nephrostomies would be least invasive, particularly given that the catheter in her neck would have to be replaced, but noted that the urology team would probably want dialysis before performing the nephrostomies.
Question 2: How can we weigh the benefits of a pain-free death within days against the benefits of a few months of extra survival but with likely additional symptoms and treatments?
This is an extremely difficult question to answer as this is such a personal decision, and even within the treating team it is possible that no consensus could be reached about where the balance lies. We noted that Mrs D had previously led a very active and independent life and much may depend on the extent to which the available treatment could offer a return, even for a short period, to this kind of life (i.e. being able to live alone at home and visit her friends, etc.) or whether she would be likely confined to hospital.
We acknowledge that death from kidney failure can be a good death in the sense that it may be peaceful and largely without pain. As you acknowledge by asking your third question, however, it is not clear what the alternative death might be (for instance, what is her prognosis if the tumour is benign?). We were advised by one of our members that even with the best palliative care, around 20% of patients can be left with some form of pain.
We agreed, however, that on face value and given consideration of the balance of harms and benefits, either more aggressive or more conservative treatment could be permissible (because this is a very personal decision). However, if you are happy with our earlier suggestions to offer some minimally invasive therapy to enhance Mrs D's capacity, some of the urgency is removed from the situation and Mrs D may be more willing to engage with this kind of issue. Indeed, she might be willing to state a preference, thus making this personal decision for herself and relieving you of your dilemma.
We agreed that such short-term minimally invasive intervention to improve her capacity would not rob Mrs D of a peaceful death because if not repeated (in the case of dialysis) or if withdrawn (in the case of the nephrostomies), she would return to her current clinical state in a matter of a few days. We also noted that if treatment was started (either to enhance her capacity or in order to delay death), she may actually find that she does not agree with the decision you have made for her and may request that treatment is withdrawn. Such a refusal would need to be respected and may, again, relieve you of your dilemma.
Question 3: Is it acceptable for this decision to be made in the absence of diagnostic certainty?
Our answer to this question is It depends for the following reasons:
We suggest that you consider enhancing Mrs D's capacity using the most minimally invasive means possible to reduce the effects of uraemia. Given that it is likely that the urologists would want to give dialysis prior to performing nephrostomies, the most minimally invasive means of achieving this end would seem to give Mrs D two or three sessions of dialysis and then re-evaluate her position, having offered her the services of an advocate and a clinical psychologist. This course of action may give you some of the answers to your other questions, though we completely accept that Mrs D could remain firm in her view that her doctors should decide for her. Please contact Dr Alldrick, our Chair, if you are uncertain about anything in this summary, and please do come back to us to discuss this case further if you feel this would be useful or if you think that we have misunderstood either the facts of the case or your questions.
