Trends in the use of opioids at the end of life and the expected effects on hastening death

Opioids, Double Effect, and the Prospects of Hastening Death

The relevance of double effect for end-of-life decision-making has been challenged recently by a number of scholars. The principal reason is that opioids such as morphine do not usually hasten death when administered to relieve pain at the end of life; therefore, no secondary "double" effect is brought about. In my article, I argue against this view, showing how the doctrine of double effect is relevant to the administration of opioids at the end of life. I contend that the prevailing view suffers from a misunderstanding of the nature of double effect, which includes application to risking a grave harm.

Counting Cases of Termination of Life without Request: New Dances with Data

This paper explores the common argument proposed by opponents of the legalization of euthanasia that permitting ending a patient's life at their request will lead to the eventual legalization of terminating life without request. The author's examination of data does not support the conclusion that a causal connection exists between legalizing ending of life on request and an increase in the number of cases without request.

Changes in attitudes towards hastened death among Finnish physicians over the past sixteen years

Background

The ethics of hastened death are complex. Studies on physicians’ opinions about assisted dying (euthanasia or assisted suicide) exist, but changes in physicians’ attitudes towards hastened death in clinical decision-making and the background factors explaining this remain unclear.

The aim of this study was to explore the changes in these attitudes among Finnish physicians.

Methods

A questionnaire including hypothetical patient scenarios was sent to 1182 and 1258 Finnish physicians in 1999 and 2015, respectively. Two scenarios of patients with advanced cancer were presented: one requesting an increase in his morphine dose to a potentially lethal level and another suffering a cardiac arrest. Physicians’ attitudes towards assisted death, life values and other background factors were queried as well. The response rate was 56%.

Results

The morphine dose was increased by 25% and 34% of the physicians in 1999 and 2015, respectively (p < 0.001). Oncologists approved the increase most infrequently without a significant change between the study years (15% vs. 17%, p = 0.689). Oncological specialty, faith in God, female gender and younger age were independent factors associated with the reluctance to increase the morphine dose. Euthanasia, but not assisted suicide, was considered less reprehensible in 2015 (p = 0.008). In both years, most physicians (84%) withheld cardiopulmonary resuscitation.

Conclusion

Finnish physicians accepted the risk of hastening death more often in 2015 than in 1999. The physicians’ specialty and many other background factors influenced this acceptance. They also regarded euthanasia as less reprehensible now than they did 16 years ago.

End-of-life decision-making across cancer types: results from a nationwide retrospective survey among treating physicians

BACKGROUND

The treatment of advanced cancer often involves potentially life-shortening end-of-life decisions (ELDs). This study aimed to examine the prevalence and characteristics of ELDs in different cancer types.

METHODS

A nationwide death certificate study was conducted based on a large random sample of all deaths in Flanders, Belgium, between 1 January and 30 June 2013. All cancer deaths were selected (n = 2392). Attending physicians were sent a questionnaire about ELDs and the preceding decision-making process.

RESULTS

The response rate was 58.3%. Across cancer types, a non-treatment decision occurred in 7.6-14.0%, intensified pain and symptom alleviation in 37.5-41.7%, euthanasia or physician-assisted suicide in 8.7-12.6%, and life shortening without explicit patient request in 1.0-2.4%. ELD prevalence did not differ significantly by cancer type. Reasons for ELDs were most frequently patient's physical suffering and lack of prospect of improvement. 'Anticipated further suffering' and 'unbearable situation for relatives' were reasons more often reported in haematological cancer than in other cancer types. Patient, family, and caregiver involvement in decision-making did not differ across cancer types.

CONCLUSIONS

Euthanasia or physician-assisted suicide rates were relatively high in all cancer types. Neither the prevalence of ELDs nor characteristics of the decision-making process differed substantially between cancer types. This indicates a uniform approach to end-of-life care, including palliative care, across oncological settings.

The association between different opioid doses and the survival of advanced cancer patients receiving palliative care

Background

Concerns that opioids may hasten death can be a cause of the physicians’ reluctance to prescribe opioids, leading to inadequate symptom palliation. Our aim was to find if there was an association between different opioid doses and the survival of the cancer patients that participated in our palliative care program.

Methods

A retrospective study was conducted at Ramathibodi Hospital, Bangkok between January 2013 and December 2015. All of the cancer patients that were referred to palliative care teams by their primary physicians were included in the study. The study data included the patients’ demographics, disease status, comorbidities, functional status, type of services, cancer treatments, date of consultation, and the date of the patient’s death or last follow-up. The information concerning opioid use was collected by reviewing the medical records and this was converted to an oral morphine equivalent (OME), following a standard ratio. The time-varying covariate in the Cox regression analysis was applied in order to determine the association between different doses of opioids and patient survival.

Results

A total of 317 cancer patients were included in the study. The median (IQR) of the OME among our patients was 6.43 mg/day (0.53, 27.36). The univariate Cox regression analysis did not show any association between different opioid doses (OME ≤ 30 mg/day and > 30 mg/day) and the patients’ survival (p = 0.52). The PPS levels (p < 0.01), palliative care clinic visits (HR 0.32, 95%CI 0.24–0.43), home visits (HR 0.75, 95%CI 0.57–0.99), chemotherapy (HR 0.32, 95%CI 0.22–0.46), and radiotherapy (HR 0.53, 95%CI 0.36–0.78) were identified as factors that increased the probability of survival.

Conclusions

Our study has demonstrated that different opioid doses in advanced cancer patients are not associated with shortened survival period.

Trends in medical end-of-life decision making in Flanders, Belgium 1998-2001-2007

In 2002, Belgium saw the enactment of 3 laws concerning euthanasia, palliative care, and patient rights that are likely to affect end-of-life decision making. This report examines trends in the occurrence and decision-making process of end-of-life practices in different patient groups since these legal changes. A large-scale retrospective survey in Flanders, Belgium, previously conducted in 1998 and 2001, was repeated in 2007. Questionnaires regarding end-of-life practices and the preceding decision-making process were mailed to physicians who certified a representative sample (N = 6927) of death certificates. The 2007 response rate was 58.4%. In patient groups in which the prevalence of life-ending drug use without explicit patient request has dropped, performance of euthanasia and assisted suicide has increased. The consistent increase in intensified pain and symptom alleviation was found in all patient groups except cancer patients. In 2007, competent patients were slightly more often involved in the discussion of end-of-life practices than in previous years. Over the years, involvement of the patient in decision making was consistently more likely among younger patients, cancer patients, and those dying at home. Physicians consulted their colleagues more often than in previous years for euthanasia and nontreatment decisions. The euthanasia law and emerging palliative care culture have substantially affected the occurrence and decision making for end-of-life practices in Belgium. Efforts are still needed to encourage shared end-of-life decision making, as some patients would benefit from advance care planning.

The labelling and reporting of euthanasia by Belgian physicians: a study of hypothetical cases

BACKGROUND

Belgium legalized euthanasia in 2002. Physicians must report each euthanasia case to the Federal Control and Evaluation Committee. This study examines which end-of-life decisions (ELDs) Belgian physicians label 'euthanasia', which ELDs they think should be reported and the physician characteristics associated with correct labelling of euthanasia cases, the awareness that they should be reported and the reporting of them.

METHODS

Five hypothetical cases of ELDs: intensified pain alleviation, palliative/terminal sedation, euthanasia with neuromuscular relaxants, euthanasia with morphine and life-ending without patient request were presented in a cross-sectional survey of 914 physicians in Belgium in 2009.

RESULTS

About 19% of physicians did not label a euthanasia case with neuromuscular relaxants 'euthanasia', 27% did not know that it should be reported. Most physicians labelled a euthanasia case with morphine 'intensification of pain and symptom treatment' (39%) or 'palliative/terminal sedation' (37%); 21% of physicians labelled this case 'euthanasia'. Cases describing other ELDs were sometimes also labelled 'euthanasia'. Factors associated with a higher likelihood of labelling a euthanasia case correctly were: living in Flanders, being informed about the euthanasia law and having a positive attitude towards societal control over euthanasia. Whether a physician correctly labelled the euthanasia cases strongly determined their reporting knowledge and intentions.

CONCLUSION

There is no consensus among physicians about the labelling of euthanasia and other ELDs, and about which cases must be reported. Mislabelling of ELDs could impede societal control over euthanasia. The provision of better information to physicians appears to be necessary.

The use of opioids at the end of life: the knowledge level of Dutch physicians as a potential barrier to effective pain management

BACKGROUND

Pain is still one of the most frequently occurring symptoms at the end of life, although it can be treated satisfactorily in most cases if the physician has adequate knowledge. In the Netherlands, almost 60% of the patients with non-acute illnesses die at home where end of life care is coordinated by the general practitioner (GP); about 30% die in hospitals (cared for by clinical specialists), and about 10% in nursing homes (cared for by elderly care physicians).The research question of this study is: what is the level of knowledge of Dutch physicians concerning pain management and the use of opioids at the end of life?

METHODS

A written questionnaire was sent to a random sample of physicians of specialties most often involved in end of life care in the Netherlands. The questionnaire was completed by 406 physicians, response rate 41%.

RESULTS

Almost all physicians were aware of the most basal knowledge about opioids, e.g. that it is important for treatment purposes to distinguish nociceptive from neuropathic pain (97%). Approximately half of the physicians (46%) did not know that decreased renal function raises plasma concentration of morphine(-metabolites) and 34% of the clinical specialists erroneously thought opioids are the favoured drug for palliative sedation.Although 91% knew that opioids titrated against pain do not shorten life, 10% sometimes or often gave higher dosages than needed with the explicit aim to hasten death. About half felt sometimes or often pressured by relatives to hasten death by increasing opioiddosage.The large majority (83%) of physicians was interested in additional education about subjects related to the end of life, the most popular subject was opioid rotation (46%).

CONCLUSIONS

Although the basic knowledge of physicians was adequate, there seemed to be a lack of knowledge in several areas, which can be a barrier for good pain management at the end of life. From this study four areas emerge, in which it seems likely that an improvement can improve the quality of pain management at the end of life for many patients in the Netherlands: 1)palliative sedation; 2)expected effect of opioids on survival; and 3) opioid rotation.

Physician-assisted deaths under the euthanasia law in Belgium: a population-based survey

BACKGROUND

Legalization of euthanasia and physician-assisted suicide has been heavily debated in many countries. To help inform this debate, we describe the practices of euthanasia and assisted suicide, and the use of life-ending drugs without an explicit request from the patient, in Flanders, Belgium, where euthanasia is legal.

METHODS

We mailed a questionnaire regarding the use of life-ending drugs with or without explicit patient request to physicians who certified a representative sample (n = 6927) of death certificates of patients who died in Flanders between June and November 2007.

RESULTS

The response rate was 58.4%. Overall, 208 deaths involving the use of life-ending drugs were reported: 142 (weighted prevalence 2.0%) were with an explicit patient request (euthanasia or assisted suicide) and 66 (weighted prevalence 1.8%) were without an explicit request. Euthanasia and assisted suicide mostly involved patients less than 80 years of age, those with cancer and those dying at home. Use of life-ending drugs without an explicit request mostly involved patients 80 years of older, those with a disease other than cancer and those in hospital. Of the deaths without an explicit request, the decision was not discussed with the patient in 77.9% of cases. Compared with assisted deaths with the patient's explicit request, those without an explicit request were more likely to have a shorter length of treatment of the terminal illness, to have cure as a goal of treatment in the last week, to have a shorter estimated time by which life was shortened and to involve the administration of opioids.

INTERPRETATION

Physician-assisted deaths with an explicit patient request (euthanasia and assisted suicide) and without an explicit request occurred in different patient groups and under different circumstances. Cases without an explicit request often involved patients whose diseases had unpredictable end-of-life trajectories. Although opioids were used in most of these cases, misconceptions seem to persist about their actual life-shortening effects.

The role of nurses in physician-assisted deaths in Belgium

BACKGROUND

Belgium's law on euthanasia allows only physicians to perform the act. We investigated the involvement of nurses in the decision-making and in the preparation and administration of life-ending drugs with a patient's explicit request (euthanasia) or without an explicit request. We also examined factors associated with these deaths.

METHODS

In 2007, we surveyed 1678 nurses who, in an earlier survey, had reported caring for one or more patients who received a potential life-ending decision within the year before the survey. Eligible nurses were surveyed about their most recent case.

RESULTS

The response rate was 76%. Overall, 128 nurses reported having cared for a patient who received euthanasia and 120 for a patient who received life-ending drugs without his or her explicit request. Respectively, 64% (75/117) and 69% (81/118) of these nurses were involved in the physician's decision-making process. More often this entailed an exchange of information on the patient's condition or the patient's or relatives' wishes (45% [34/117] and 51% [41/118]) than sharing in the decision-making (24% [18/117] and 31% [25/118]). The life-ending drugs were administered by the nurse in 12% of the cases of euthanasia, as compared with 45% of the cases of assisted death without an explicit request. In both types of assisted death, the nurses acted on the physician's orders but mostly in the physician's absence. Factors significantly associated with a nurse administering the life-ending drugs included being a male nurse working in a hospital (odds ratio [OR] 40.07, 95% confidence interval [CI] 7.37-217.79) and the patient being over 80 years old (OR 5.57, 95% CI 1.98-15.70).

INTERPRETATION

By administering the life-ending drugs in some of the cases of euthanasia, and in almost half of the cases without an explicit request from the patient, the nurses in our study operated beyond the legal margins of their profession.

Physician reports of medication use with explicit intention of hastening the end of life in the absence of explicit patient request in general practice in Belgium

BACKGROUND

Although the incidence of the use of life-ending drugs without explicit patient request has been estimated in several studies, in-depth empirical research on this controversial practice is nonexistent. Based on face-to-face interviews with the clinicians involved in cases where patients died following such a decision in general practice in Belgium, we investigated the clinical characteristics of the patients, the decision-making process, and the way the practice was conducted.

METHODS

Mortality follow-back study in 2005-2006 using the nationwide Sentinel Network of General Practitioners, a surveillance instrument representative of all GPs in Belgium. Standardised face-to-face interviews were conducted with all GPs who reported a non-sudden death in their practice, at home or in a care home, which was preceded by the use of a drug prescribed, supplied or administered by a physician without an explicit patient request.

RESULTS

Of the 2690 deaths registered by the GPs, 17 were eligible to be included in the study. Thirteen interviews were conducted. GPs indicated that at the time of the decision all patients were without prospect of improvement, with persistent and unbearable suffering to a (very) high degree in nine cases. Twelve patients were judged to lack the competence to make decisions. GPs were unaware of their patient's end-of-life wishes in nine cases, but always discussed the practice with other caregivers and/or the patient's relatives. All but one patient received opioids to hasten death. All GPs believed that end-of-life quality had been "improved considerably".

CONCLUSIONS

The practice of using life-ending drugs without explicit patient request in general practice in Belgium mainly involves non-competent patients experiencing persistent and unbearable suffering whose end-of-life wishes can no longer be ascertained. GPs do not act as isolated decision-makers and they believe they act in the best interests of the patient. Advance care planning could help to inform GPs about patients' wishes prior to their loss of competence.

Continuous deep sedation in medical practice: a descriptive study

CONTEXT

Continuous deep sedation (CDS) until death can form an effective part of palliative care. In The Netherlands and Belgium, CDS is sometimes regarded as an alternative to euthanasia, and the involvement of palliative care specialists is low. Provision of CDS through opioids alone is not recommended.

OBJECTIVES

This study investigates the use of CDS in the United Kingdom.

METHODS

A survey of 8,857 doctors, of whom 3,733 (42%) replied, with 2,923 reporting on their last patient who died.

RESULTS

In total, 18.7% (17.3-20.1) of the doctors attending a dying patient reported the use of CDS. CDS was more likely when patients were younger or were dying of cancer. Specialists in care of the elderly were least likely to report the use of CDS; doctors in other hospital specialties were most likely to report its use. CDS was associated with a higher rate of requests from patients or relatives for a hastened death and with a greater incidence of other end-of-life decisions containing some intent to end life by the doctor. Doctors supporting legalization of euthanasia or physician-assisted suicide, or who were nonreligious, were more likely to report using CDS. There was palliative care team involvement in half of all CDS cases, and prescription of opioids alone for sedation occurred in one-fifth of the cases but was not reported by specialists in palliative care.

CONCLUSION

This study provides baseline data for monitoring future trends in the United Kingdom and highlights the need for a fuller understanding of the circumstances in which CDS occurs in particular care settings.

Policy statements and practice guidelines for medical end-of-life decisions in Dutch health care institutions: developments in the past decade

OBJECTIVES

To describe the existence of policy statements on euthanasia and physician-assisted suicide (EAS) and practice guidelines for all medical end-of-life decisions in Dutch health care institutions in 2005, whether the existence of practice guidelines is related to characteristics of institutions, and to compare the existence of policies in 2005 and 1994.

METHODS

Questionnaires were sent to 566 institutions (all Dutch hospitals, nursing homes, general psychiatric hospitals, institutions for the mentally disabled, hospices) from October 2005 through March 2006.

RESULTS

Most institutions (70%) had a written policy statement concerning EAS. EAS was usually allowed under specific conditions (75%). Institutions mainly had practice guidelines for EAS and do-not-resuscitate decisions (62% and 63%). A minority had guidelines on palliative sedation (27%), alleviation of symptoms (27%) and withdrawing or withholding treatment (33%). In general, there were more practice guidelines in 2005 than in 1994. Larger institutions and institutions with an ethics committee more often had practice guidelines. Religious affiliation of an institution did not seem to be related to the existence of guidelines.

CONCLUSIONS

Since many institutions still do not have practice guidelines for medical end-of-life decisions, they should be stimulated to introduce practice guidelines, being a first step in improving the quality of the care on institutional level.
