    EDITOR, - The editorial and papers on decisions regarding cardiopulmonary resuscitation show the importance of involving patients and establishing written policies.*RF 1-3* We agree with these authors' conclusions but would sound a cautionary note.

    Some months ago we instituted a policy whereby mentally competent patients admitted to the unit were routinely asked whether they would want cardiopulmonary resuscitation. Our experience was similar to that described by Morgan and colleagues,3 with most patients welcoming being involved and wishing to express an opinion. However, on one occasion a relative took exception to the practice and contacted her MP and the local press and television. We were then both accused of running a covert euthanasia policy and attempting to withdraw treatment from elderly patients in order to save money. In the furore that followed we saw how the issue of withholding cardiopulmonary resuscitation is easily confused by the lay public with euthanasia.

    While it must be ethically right that patients are involved in these decisions, great care needs to be taken in how their views are ascertained. Who asks patients, when and how they are asked, and which patients are excluded? Is the patient's view always binding, or is it to be considered as part of the overall decision making process? These are all vital questions to address when setting up such a policy. Unfortunately, in practice, it is often easier to avoid these difficult and complex issues - to continue with tradition and let the doctor decide.

    Explaining outcomes may change views

    1. J Liddle

      EDITOR, - As mentioned by Dominique Florin in her editorial,1 I found a discrepancy between elderly patients wishing cardiopulmonary resuscitation and their doctors' decisions on cardiopulmonary resuscitation - 78 of 100 patients wished resuscitation but only 11 were designated for resuscitation.2 In view of this, I looked at the effect of giving information, including success rate on cardiopulmonary resuscitation, to the patients.

      I interviewed a further 20 elderly inpatients (mean age 82 years), asking them if they would have wished to have been resuscitated during their hospital stay and their desirability to resuscitate specific patient groups. Their answers are shown in the table.

      Effect of information sheet on wishes regarding cardiopulmonary resuscitation

      View this table:

      The patients then read an information sheet which stated,“Resuscitation, which is the procedure we do when a patient has a cardiac arrest, involves: cardiac massage, care of the airway and giving oxygen, giving relevant drugs into a vein and applying electric shock to the chest when appropriate. Successfully restarting the heart in older people is often difficult to achieve.” Once they had understood the information, I then asked, “Does this information alter your views on wanting to be resuscitated yourself?” Fourteen of these 20 patients did not change their wish. The table shows the results for the other patient groups. Thirteen of the patients said they would not have wanted to have been given this information on admission and 12 would not have wanted their relatives to have been given it.

      These preliminary results suggest the need for a larger study to examine the effects of giving patients more information on cardiopulmonary resuscitation.

      Is assumption of consent justified?

      1. F Haas

        EDITOR, - Discussions on consent to cardiopulmonary resuscitation remain academic while the public is in such ignorance of the procedure. One nursing auxiliary made the comment that the first arrest that she witnessed “wasn't like on television” where everyone runs and in two minutes either a straight line on the monitor signal death or the patient sits up and recovers.

        Medical ethicists insist on the right to lifesaving treatment but ignore the fact that, in practice, only very rarely is cardiopulmonary resuscitation a single event. In most cases it begins a train of interventions that include ventilation and transfer to intensive care. Of the approximately 44% of patients that survive the initial arrest, 32% are expected to survive to discharge. The remaining 68% may experience a lingering death in hospital.

        We know that a certain number of patient will have a cardiac arrest and that, at the time consent cannot be obtained. Are we justified in continuing the present practice of assuming that all patients want cardiopulmonary resuscitation? In Marguerite E Hill's survey all patients felt that resuscitation should be discussed with them, and more than half the women over 60 did not wish for resuscitation.2 Do we accept that patients are entitled to realistic information on cardiopulmonary resuscitation and the right to make their own decisions?

        When medical futility is the reason for a non-resuscitation decision this should ideally be discussed with the patient. This can encourage consideration of other treatment issues and offer the patient the opportunity to talk of hopes and fears.3 However, this is sometimes impractical or there is no time. A lack of prior discussion should not oblige a team to carry out a pointless procedure. To use breast cancer as an analogy, a doctor would not be expected to provide a liver transplant for a breast cancer patient with liver metastases. Unless the patient raised the matter independently, the doctor would not need to discuss this. Similarly, the only time when consent need not be routinely sought is when survival of cardiopulmonary resuscitation is very unlikely.

        Change is difficult. Discussion on cardiopulmonary resuscitation with most patients would be time consuming, though there would eventually be savings in the time of skilled medical personnel if some unwanted resuscitation attempts were avoided. Nurses often know that a patient does not “want to go on.” Though doctors could not base a non- resuscitation decision solely on a nurse's report, good interdisciplinary communication would promote patient autonomy.

        Should we question the assumption of consent for such a violent, invasive procedure that precludes the possibility of a peaceful death?

        Futile treatment need not be offered

        1. N J Dudley

          EDITOR, - The advice given to R Morgan and colleagues by the Medical Protection Society and the Medical Defence Union that “legally if a patient requests cardiopulmonary resuscitation it should be provided” is both ill considered and, in the light of published work, incorrect.1 Doctors are not obliged to offer futile treatment even if the treatment is demanded by a patient or a patient's family.

          Studies investigating survival from cardiopulmonary resuscitation have shown repeatedly that for certain conditions such as pneumonia and metastatic malignancy this treatment is of no medical benefit, with survival rate of, or approaching, 0%.2 Similarly, George et al and O'Keeffe et al have shown that the morbidity index before cardiac arrest identifies patients who will not survive an attempt at resuscitation.3,4 The index is a weighted scoring system based on diagnoses, clinical observations, and biochemical findings. The score associated with failure to survive was >=9 in George et al's study and >=5 in O'Keeffe et al's study.

          Should a doctor take the advice of the defence societies and comply with a request for cardiopulmonary resuscitation from a patient who has metastatic bronchial carcinoma and is admitted to hospital with septicaemia and hypotension due to pneumonia? Published survival studies suggest a 0% survival rate after a cardiac arrest in such cases. The morbidity score for such a patient before an arrest is 10, indicating that he or she would not survive an attempt at resuscitation. Thus a request for cardiopulmonary resuscitation should be declined, and the reason for this should be discussed with the patient and his or her family.

          The Medical Defence Union and Medical Protection Society should reevaluate their advice before a doctor is faced with unnecessary litigation. Is it really illegal for a doctor to withhold a requested treatment that is of no medical benefit? Professional judgment and common sense suggest that it is not.

          Discuss implications with the patient

          1. J A Carter

            EDITOR, - I wish to add a further dimension to Dominique Florin's editorial on decisions about cardiopulmonary resuscitation.1 For a “do not resuscitate” order to be humane, ethical, appropriate, and perhaps legal a senior doctor needs to be prepared to discuss with the patient, probably at length, the implications of his or her illness. Such discussion should cover the implications in relation to cardiopulmonary first aid; subsequent intensive care (this is often neglected: a patient who is successfully resuscitated after a respiratory or cardiac arrest often requires further intensive care); prolonged recovery; and uncertain outcome with the possibility of dependent survival. This discussion with the patient may be duplicated with concerned relatives.

            A do not resuscitate order, if it is to be appropriate, also needs to be reassessed in the light of the patient's changing health and wishes almost daily. Some of the manifest deficiencies in the present system have arisen because of lack of time. Doctors of all grades are in short supply in the NHS.

            Those of us who work in intensive care see that dying is not always the worst outcome for our patients. Partially sucessful resuscitation followed by a variable period of progressively futile intensive therapy followed by death is a far sadder end and could perhaps be avoided more often if the issues were faced earlier in the patient's illness.

            Terminally ill patients may want to live

            1. C J N Meystre,
            2. S Ahmedzai,
            3. N M J Burley

              EDITOR, - In their short report on decision making in cardiopulmonary resuscitation Marguerite E Hill and colleagues state that one third of the doctors they surveyed would attempt to resuscitate patients with incurable malignancy but that patients' requests for resuscitation declined with increasing age.1 We have conducted an interview survey into hospice patients' attitudes to investigations and invasive procedures.

              The interviews were done by medical students, who were not identified as being connected with the hospice. Twenty three randomly selected inpatients at Leicestershire Hospice, all of whom had incurable and advanced malignancy, were interviewed. If a patient did not understand any question the procedure was explained in a standard way. One of the 14 questions was, “If your heart stopped unexpectedly would you want to be resuscitated?” Eleven patients answered “Yes, definitely” and eight answered “No, definitely.” One patient wanted resuscitaion and another did not want it but were less definite; two patients answered “Don't know.”

              These responses were not related to the patients' age or their self assessed World Health Organisation performance (activity) status. Only one patient became emotional when discussing resuscitation. When the key nurses of these 23 patients were asked about resuscitation in the event of an unexpected cardiac arrest all answered that it would be inappropriate. There was thus a considerable discordance between the responses of the terminally ill patients and their nursing carers, even though patients' and nurses'ratings of performance status were highly correlated (r=0.78, n=23, df=21, P<0.001).

              Hospice care aims to improve quality of life rather than to prolong life. This unit has held a policy of not resuscitating patients, and this policy is clearly reflected in the nurses' responses. The question of resuscitation is not routinely discussed with patients or relatives. In the light of our findings and the legal obligation to provide cardiopulmonary resuscitation if it is desired2 we believe that we should be even more careful to discuss treatment options and listen to patients' wishes and to educate them about possible outcomes. Perhaps the most important lesson is that even a terminally ill patient with an incurable malignancy may find life worthwhile and precious.
