Therapeutic ratio and defined phases: proposal of ethical framework for palliative care

A 'pain-free' death

BACKGROUND

The time around a patient's death is often filled with sadness, but good medical and nursing care can provide comfort to patients and their carers at this critical time. For many, a 'pain-free' death is a priority although there are other aspects to providing good care at the end of life. Honest, open discussion with patients and carers about their wishes is an essential prerequisite to individualized care.

SOURCES OF DATA

Relevant literature was reviewed with regards to policy, education and delivery of end of life care.

AREAS OF AGREEMENT

Pain management must be tailored to the individual with due regard to the route of analgesic administration in those unable to swallow, and consideration to the other circumstances surrounding a person's care. All staff caring for dying patients should address pain as a priority in managing end of life care, to promote the best possible death for patients and prevent undue distress for carers and staff.

AREAS OF CONTROVERSY

This review has approached patient care at the end of life within current UK legislation, outlining what can be done to promote a 'pain-free' death. Debate continues about the role of euthanasia within end of life care and the use of analgesics and sedatives in pain management in terminal care.

GROWING POINTS

There is a range of tools available to help staff to care for dying patients, such as the Liverpool Care Pathway (LCP) for the Dying. It is most effective when introduced as part of a wider system of staff education in relation to terminal care.

AREAS TIMELY FOR DEVELOPING RESEARCH

Research into care of the dying will continue to be challenging. Priorities include; whether the use of tools such as the LCP improve the care patients receive, and the development of routine outcome measures including validated reports from patients and proxies.

Resolving conflict in end‐of‐life care

We need to acknowledge the inevitability of death to have some choice in the manner of our dying.

Gardner; re BWV: Victorian Supreme Court makes landmark Australian ruling on tube feeding

The Victorian Supreme Court has decided that artificial nutrition and hydration provided through a percutaneous gastrostomy tube to a woman in a persistent vegetative state may be withdrawn. The judge ruled, in line with a substantial body of international medical, ethical and legal opinion, that any form of artificial nutrition and hydration is a medical procedure, not part of palliative care, and that it is a procedure to sustain life, not to manage the dying process. Thus, the law does not impose a rigid obligation to administer artificial nutrition or hydration to people who are dying, without due regard to their clinical condition. The definition of key terms such as "medical treatment", "palliative care", and "reasonable provision of food and water" in this case will serve as guidance for end-of-life decisions in other states and territories. The case also reiterates the right of patients, and, when incompetent, their validly appointed agents or guardians, to refuse medical treatment. Where an incompetent patient has not executed a binding advance directive and no agent or guardian has been appointed, physicians, in consultation with the family, may decide to withdraw medical treatment, including artificial nutrition or hydration, on the basis that continuation of treatment is inappropriate and not in the patient's best interests. However, Victoria and other jurisdictions would benefit from clarification of this area of the law.

A prospective evaluation of patients undergoing surgery for the palliation of an advanced malignancy

BACKGROUND

Decisions regarding the use of surgical procedures for the palliation of symptoms caused by advanced malignancies require the highest level of surgical judgment. Prospective analysis of palliative surgical care may facilitate a more effective and representative evaluation of these patients.

METHODS

Patients requiring surgery planned solely for the palliation of an advanced malignancy were offered entry onto this study. Outcome measurements were made before surgery and monthly thereafter until the patient's death. Accepted techniques of pain assessment, quality of life, and functional status were used.

RESULTS

Between May 1997 and December 1999, 26 patients were enrolled. Although 46% (12 of 26) of patients demonstrated improvement in pain control or quality of life after palliative surgery, these benefits lasted a median of only 3.4 months. Palliative surgery was associated with significant postoperative complications in 35% (9 of 26) patients.

CONCLUSIONS

Although many patients had no apparent demonstrable benefit from surgery, surgeons were able to identify a group of patients who experienced significant benefits after a palliative procedure. The relationships between the patient and family members and the surgeon play an important role in decision-making throughout the palliative phase of cancer treatment.

Users' views on palliative care services: ethical implications

This article is based on the findings of a study that elicited the views of terminally ill patients (n = 15), their carers (n = 10) and bereaved carers (n = 19) on the palliative care services they received. It explores the range of ethical issues revealed by the data. Although the focus of the original study was on community services, the participants frequently commented on all aspects of their experience. They described some of its positive and negative aspects. Of concern was the reported lack of sensitivity to the role of the family among health professionals. The family, as carers, service users and advocates, represent a challenge to professional boundaries and the ethical norms of confidentiality and best interest. The accounts reveal the complexity of the ethical issues that characterize terminal care, issuing specific ethical challenges to nurses and other health professionals involved in this field.

Decision making on surgical palliation based on patient outcome data

BACKGROUND

Strategies for the effective application of palliative procedures are infrequently standardized and incompletely understood. The effect on patient outcome as determined by elements such as resolution of chief complaints, quality of life, pain control, morbidity of therapy, and resource utilization should predominate decisions regarding surgical palliative care.

METHODS

Articles published between 1990 and 1996 on the surgical palliation of cancer were identified by a MEDLINE search and reviewed for designated parameters considered important for good palliative care.

RESULTS

A total of 348 citations were included. Entries considered these fundamental elements: cost (2%); pain control (12%); quality of life (17%); need to repeat the intervention (59%); morbidity and mortality (61 %); survival (64%); and physiologic response (69%). Established methods for quality of life and pain assessment were sporadically utilized.

CONCLUSIONS

In the current surgical literature, there is uncommon reporting of the range of data required to recommend sound palliative surgical choices.

The Double Effect of Pain Medication: Separating Myth from Reality

The principle of double effect is used to justify the administration of medication to relieve pain even though it may lead to the unintended, although foreseen, consequence of hastening death by causing respiratory depression. Although a review of the medical literature reveals that the risk of respiratory depression from opioid analgesic is more myth than fact and that there is little evidence that the use of medication to control pain hastens death, the belief in the double effect of pain medication remains widespread. Applying the principle of double effect to end-of-life issues perpetuates this myth and results in the undertreatment of physical suffering at the end of life. The concept of double effect of opioids also has been used in support of legalization of physician-assisted suicide and euthanasia.

Ethical issues in pain management

The modern hospice movement has played a significant role in the development of palliative care. Effective palliation is of crucial importance in achieving quality of life and a dignified death for the terminally ill. While the inherent risk in palliative care, respiratory depression, remains an open medical question, an understanding of the ethical and moral principle of double effect demonstrates the prudential nature of palliative care and how it is an application of the ethical and moral norm, respect for patient autonomy.

On withholding artificial hydration and nutrition from terminally ill sedated patients. The debate continues

The author reviews and continues the debate initiated by her recent paper in this journal. The paper was critical of certain aspects of palliative medicine, and caused Ashby and Stoffell to modify the framework they proposed in 1991. It now takes account of the need for artificial hydration to satisfy thirst, or other symptoms due to lack of fluid intake in the terminally ill. There is also a more positive attitude to the emotional needs and ethical views of the patient's family and care-givers. However, clinical concerns about the general reluctance to use artificial hydration in terminal care remain, and doubts persist about the ethical and legal arguments used by some palliative medicine specialists and others, to justify their approach. Published contributions to the debate to date, in professional journals, are reviewed. Key statements relating to the care of sedated terminally ill patients are discussed, and where necessary criticised.

The last 3 months of life of cancer patients: medical aspects and role of home-care services in southern Switzerland

The clinical data on terminal cancer patients who have died since the establishment of a program of collaboration between community services and the cancer center of Canton of Ticino, southern Switzerland, were retrospectively analyzed to describe the characteristics of patients seen and the effect on them of a home-care program coordinated by the cancer center. The home-care program is based on five geographically grouped community-based domiciliary services, with the addition of one nurse responsible for coordination and one physician from the oncology center. Selection criteria for participation in the home-care program are defined. The main outcome measures were: number of hospitalizations and median hospital stay during the last 3 months of life; reasons for and median length of last hospitalization; place of death of patients who had home care and those who did not. In the group of 993 patients analyzed, the median contact time with the cancer center was 9.5 months (10th percentile: 1 month, 90th percentile: 71 months); the most frequent neoplasm was lung cancer (22%) with the briefest contact time (7.5 months; 10th percentile: 1 month; 90th percentile: 21 months); 13.5% of patients were never hospitalized; half of the patients had a total hospital stay of 24 days or longer and 23% died at home. The sociodemographic and medical characteristics of home-care users were similar to those of the home-care non-users and to those of the overall group. In the group of home-care users (32% of the total) 22% were never hospitalized, half of the patients had a total hospital stay of 17 days or longer, and 43.5% of them died at home. These values were significantly different (P > 0.001) from those reported in the group of home-care non-users. Palliative care, provided at home through community-based domiciliary services, is associated with less frequent and shorter hospitalizations in the last 3 months of life. Medical oncology and palliative treatments should be mutually complementary to improve patients care. Cancer centers should be involved in the planning and coordination of supportive-care domiciliary services.

Appropriate palliative care: when does it begin?

The transition between a curative and a palliative approach to the care of a patient with cancer may be filled with uncertainty for patients, their families and health care professionals. A conventional model of treating the patient with cancer through curative, palliative and terminal phases is examined. The boundaries between the phases of care are blurred. A model of care based on respect for patient autonomy ensures that the timing of the switch from curative to palliative care is appropriate.

Rehydration in palliative and terminal care: if not--why not?

Patients who are in the last few days of life are often too frail to take oral fluids and nutrition. This may be due entirely to the natural history of their disease, although the use of sedative drugs for symptom relief may contribute to a reduced level of consciousness and thus a reduced oral intake. Rehydration with intravenous (i.v.) fluids is the usual response in acute care settings, whereas the hospice movement has often argued against this approach. The issues are complex and involve not only physical, psychological and social concerns, but also ethical dilemmas. A review of the literature gives conflicting reports of the physical discomfort that may be attributed to dehydration in dying patients. There are many confounding variables, including the concomitant use of antisecretory drugs, mouth breathing and oral infection. It remains unproven whether i.v. fluids offer symptomatic relief in this situation. Hospice doctors are concerned that the use of i.v. fluids gives confusing messages to relatives about the role of medical intervention at this stage in a patient's illness. A drip may cause a physical barrier between a patient and their loved one at this important time. The use of other methods of fluid replacement are discussed. In the absence of definitive research in this area, the balance of the burdens and benefits of such treatment remains subjective. The prime goal of any treatment in terminal care should be the comfort of the patient. Decisions should be made on an individual basis, involving both patients and their carers wherever possible. Prolonging life in such circumstances is of secondary concern and i.v. fluids given in this context may be futile. The ethical dilemmas of withholding and withdrawing medical treatment in addition to those of conducting research in this area are discussed.

Artificial hydration and alimentation at the end of life: a reply to Craig

Dr Gillian Craig (1) has argued that palliative medicine services have tended to adopt a policy of sedation without hydration, which under certain circumstances may be medically inappropriate, causative of death and distressing to family and friends. We welcome this opportunity to defend, with an important modification, the approach we proposed without substantive background argument in our original article (2). We maintain that slowing and eventual cessation of oral intake is a normal part of a natural dying process, that artificial hydration and alimentation (AHA) are not justified unless thirst or hunger are present and cannot be relieved by other means, but food and fluids for (natural) oral consumption should never be 'withdrawn'. The intention of this practice is not to alter the timing of an inevitable death, and sedation is not used, as has been alleged, to mask the effects of dehydration or starvation. The artificial provision of hydration and alimentation is now widely accepted as medical treatment. We believe that arguments that it is not have led to confusion as to whether or not non-provision or withdrawal of AHA constitutes a cause of death in law. Arguments that it is such a cause appear to be tenuously based on an extraordinary/ordinary categorisation of treatments by Kelly (3) which has subsequently been interpreted as prescriptive in a way quite inconsistent with the Catholic moral theological tradition from which the distinction is derived. The focus of ethical discourse on decisions at the end of life should be shifted to an analysis of care, needs, proportionality of medical interventions, and processes of communication.

On withholding nutrition and hydration in the terminally ill: has palliative medicine gone too far?

This paper explores ethical issues relating to the management of patients who are terminally ill and unable to maintain their own nutrition and hydration. A policy of sedation without hydration or nutrition is used in palliative medicine under certain circumstances. The author argues that this policy is dangerous, medically, ethically and legally, and can be disturbing for relatives. The role of the family in management is discussed. This issue requires wide debate by the public and the profession.

Indicators of quality medical care for the terminally ill in nursing homes

PURPOSE

To identify medical care indicators for nursing home terminal care.

DATA SOURCES

Studies examining care of terminally ill patients were identified using computer, bibliography, and expert searches; input from nursing home medical directors in Maryland; and input from expert geriatricians.

STUDY SELECTION

More than 900 articles, books, and abstracts from meetings covering medical care for terminally ill patients were reviewed. Information from more than 100 publications is included.

DATA EXTRACTION

Indicators of medical care for terminally ill patients, which can be used to quantify performance with respect to standards, guidelines, and options, were identified initially through review of the literature.

DATA SYNTHESIS

Indicators were refined by input from medical directors of Maryland long-term care facilities and subsequent review by expert geriatricians.

CONCLUSIONS

Minimum standards for which 100% performance is expected are communication of advance directives, attention to pain control, and attention to relief of dyspnea. Performance indicators for medical care guidelines and options in terminal care of nursing home patients are also described.

Hospice management of patients receiving cytotoxic chemotherapy: problems and opportunities

In Britain, the specialty of palliative medicine continues to develop, encouraging the referral of patients early in the palliative phase of their illness. This had led to an increased number of patients receiving palliative chemotherapy and hospice care concurrently, posing special problems to the professionals involved. In this retrospective study, 52 patients were identified who received chemotherapy and hospice care simultaneously. Case notes were reviewed to reveal problems arising from sharing the duty of care. The poor quality of communication between professionals, perhaps reflecting a limited understanding of the various roles in patient care, we found to cause significant difficulties. The duration and discontinuation of cytotoxic therapy seems to be a particularly difficult matter. Hospice admission often signalled the end of this treatment. In a third of the patients, no decision was taken to stop chemotherapy despite the last dose being an average of just 1 week before death. The value of chemotherapy for patients who are too ill to return home is questioned. Seven patients were diagnosed as suffering from chemotherapy-induced sepsis and neutropenia either by hospice inpatient or home care teams, and were admitted to their acute centres accordingly. Most patients who died during the study period received terminal care in the hospice. Suggestions are made on improving professional education and communication, including the use of a 'chemotherapy card'.

General practitioners and palliative care

A randomly selected sample of 158 South Australian general practitioners (GPs) were sent a questionnaire which assessed opinions and management practices in the palliative care of terminally ill patients. A total of 117 responses (74%) were received. Most GPs were at least moderately satisfied with the care they were able to give their terminally ill patients, although a substantial number reported difficulties in pain and other symptom control, dealing with relatives' emotional distress and attending to patients' psychosocial needs. There was considerable support for continuing education in these aspects of palliative care. More than half were at least somewhat concerned by opioid side effects and impairment of cognitive function, although opioid dependence was not a concern. Considerable dissatisfaction was expressed with public hospital care for the terminally ill and most felt excluded from decision-making once their patients were admitted. The findings suggest that continuing education is required for GPs and that palliative care should become an integral part of undergraduate education. There is also a need to enhance communication and co-ordination between hospital and community-based services for the terminally ill.

The role of radiotherapy in palliative care

Radiotherapy is an indispensable modality in the palliation of cancer. All palliative care programs should be acquainted with its indications and have a close working relationship with a radiation oncology department. The technical aspects of the subject may be intimidating to many staff and patients, and departments need to improve their outreach and education. The main indications are: pain relief (particularly bone pain), control of hemorrhage, fungation and ulceration, dyspnea, blockage of hollow viscera, and the shrinkage of any tumors causing problems by virtue of space occupancy. In addition, it has an important role in the palliation of three oncological emergencies: superior vena caval obstruction, spinal cord compression, and raised intracranial pressure due to cerebral metastases. More pragmatic fractionation schedules are being developed that are compatible with good results in terms of palliative end points, giving shorter courses with fewer hospital attendances for patient and family comfort and convenience. More clinical research and evaluation of palliative radiotherapy are required.
