Regulating physician-assisted dying for minors in the Netherlands: views of paediatricians and other physicians.

AIM: In 2002, the Dutch Euthanasia Act came into effect, which made euthanasia available to individuals from the age of 12 and above. The objective of our study was to gain insight into how Dutch paediatricians and other physicians treating children feel about the regulation of physician-assisted dying. METHODS: We interviewed 63 paediatricians, 125 general practitioners and 208 clinical specialists about their views on physician-assisted dying and the Euthanasia Act. RESULTS: Of the paediatricians, 44% agreed with the age limit of 12 years, and 52% agreed with the requirement that parents be involved. Somewhat more than half thought the Act could contribute to the disclosure of end-of-life practices (52%), the quality of the review procedure (61%), careful decision making (54%) and the reporting rate (65%). These percentages were comparable for other physicians. A minority of the physicians in all groups indicated that, with this Act in place, they would be more willing to report such practices. The most optimistic in this respect were the paediatricians, of whom 39% expected such an effect. CONCLUSIONS: About half of Dutch paediatricians support the Euthanasia Act and expect it to achieve its aims, which is the same percentage as was found for other clinical specialists and general practitioners. However, most physicians do not foresee an increase in willingness to report cases of physician-assisted dying.

Communication about euthanasia in general practice: opinions and experiences of patients and their general practitioners.

OBJECTIVE: Public opinion and professional organisations dominate the euthanasia debate, and there is a need to understand the opinions of people confronted with euthanasia. The aim of this study was to investigate whether patients and their GPs talk about euthanasia, and if so, how they communicate about this. METHODS: Qualitative, semi-structured interviews were held with 20 GPs and 30 of their patients in primary care in the Netherlands, where euthanasia is legalised. The patients had a life expectancy of less than 6 months, and cancer, heart failure or chronic obstructive pulmonary disease as underlying disease. RESULTS: Many patients did not communicate about euthanasia with their GP. Neither the patient nor the GP were clear in formulating their expectations concerning future decision making. CONCLUSION: The initial patient-GP communication consisted of an exchange of opinions about situations in which euthanasia would be desirable. GPs had different opinions about who should initiate communication, and found it difficult to judge the right moment to talk. PRACTICE IMPLICATIONS: It is essential to pay attention to education in communication about dying and euthanasia and to train the GPs to gain insight in the patient's end-of-life preferences, and to direct care at the best possible quality of life.

Predictors of mortality for lower respiratory infections in nursing home residents with dementia were validated transnationally.

BACKGROUND AND OBJECTIVE: Generalizability of clinical predictors for mortality from lower respiratory infection (LRI) in nursing home residents has not been assessed for residents with dementia. STUDY DESIGN AND SETTING: In prospective cohort studies of LRI in 61 nursing homes in the Netherlands (n = 541) and 36 nursing homes in Missouri, USA (n = 564), we examined 14-day and 1- and 3-month mortality in residents with dementia who were treated with antibiotics. RESULTS: A logistic model predicting 14-day mortality derived from Dutch data included eating dependency, elevated pulse, decreased alertness, respiratory difficulty, insufficient fluid intake, high respiratory rate, male gender, and pressure sores. After adjusting coefficients with the heuristic shrinkage factor, the 14-day model showed good discrimination and calibration in both datasets. The apparent c-statistic for the original Dutch model was 0.80 (after correction for optimism, it was 0.75); the c-statistic was 0.74 in the U.S. validation population. The models predicting 1- and 3-month mortality showed moderate performance. A scoring system for estimating 14-day mortality performed equally well as the original model. CONCLUSION: We identified a set of credible clinical predictors that are easily assessed and demonstrated validity in identifying residents at low risk of dying from LRI across different nursing home populations. This tool should inform decision-making for families and doctors.

Trends in acceptance of euthanasia among the general public in 12 European countries (1981-1999).

BACKGROUND: We wanted to examine how the acceptance of euthanasia among the general public in Western Europe has changed in the last decades, and we wanted to look for possible explanations. METHODS: We analysed data from the European Values Surveys, held in 1981, 1990, and 1999-2000 in 12 West European countries. In each country, representative samples of the general public were interviewed using the same structured questionnaire in all countries. Euthanasia was explained in the questionnaires as 'terminating the life of the incurably sick'. RESULTS: A total of 46 199 respondents participated in the surveys. A significant increase in acceptance of euthanasia could be observed in all countries except (West) Germany. While the average increase in euthanasia acceptance was 22%, the increase was particularly obvious in Belgium, Italy, Spain, and Sweden. Although changes in several characteristics of respondents, such as decrease in religious beliefs, rising belief in the right to self-determination, and (to a lesser extent) rise in levels of education, were associated with growing acceptance of euthanasia, they could only partly explain the increase of euthanasia acceptance over the years. CONCLUSIONS: An increase of euthanasia acceptance among the general public took place over the last two decades in almost all West European countries, possibly indicating a growing support for personal autonomy regarding medical end-of-life decisions. If this trend continues, it is likely to increase the public and political debate about the (legal) regulation of euthanasia under certain conditions of careful medical practice in several West European countries.

End-of-life decision making in Europe and Australia: a physician survey.

BACKGROUND: The frequencies with which physicians make different medical end-of-life decisions (ELDs) may differ between countries, but comparison between countries has been difficult owing to the use of dissimilar research methods. METHODS: A written questionnaire was sent to a random sample of physicians from 9 specialties in 6 European countries and Australia to investigate possible differences in the frequencies of physicians' willingness to perform ELDs and to identify predicting factors. Response rates ranged from 39% to 68% (N = 10 139). Using hypothetical cases, physicians were asked whether they would (probably) make each of 4 ELDs. RESULTS: In all the countries, 75% to 99% of physicians would withhold chemotherapy or intensify symptom treatment at the request of a patient with terminal cancer. In most cases, more than half of all physicians would also be willing to deeply sedate such a patient until death. However, there was generally less willingness to administer drugs with the explicit intention of hastening death at the request of the patient. The most important predictor of ELDs was a request from a patient with decisional capacity (odds ratio, 2.1-140.0). Shorter patient life expectancy and uncontrollable pain were weaker predictors but were more stable across countries and across the various ELDs (odds ratios, 1.1-2.4 and 0.9-2.4, respectively). CONCLUSION: Cultural and legal factors seem to influence the frequencies of different ELDs and the strength of their determinants across countries, but they do not change the essence of decision making.

Quality of consultation and the project 'Support and Consultation on Euthanasia in the Netherlands' (SCEN).

OBJECTIVE: Consultation of another physician is one of the requirements for prudent practice. The project 'Support and Consultation on Euthanasia in the Netherlands' (SCEN) is aimed at professionalizing consultation. The objective of this study is to assess whether the quality of consultation was improved through SCEN. METHOD: In four districts all general practitioners (GPs) received a pre-test questionnaire approximately six weeks before the start of the project in the period (n=1224, response 71%). In the period from April 2000 to December 2002, all GPs in districts in which SCEN had been implemented received a written post-test questionnaire one and a half years after the start of the project. This post-test questionnaire was returned by 60% of the GPs (n=3614). RESULTS: In SCEN consultations the attending physicians has no specific relation to the attending physician in 85% of consultations, while this is the case for 31% of other consultations. While before the start of SCEN in 71% of consultations six or seven of the seven criteria for good consultation were met, in SCEN consultations 83% of cases six or seven of these requirements were met. GPS who had consulted a SCEN physician generally were more positive about different aspects than those who consulted another consultant, such as considering the consultant to be able to make an independent judgement (totally agree 74% versus 59%). CONCLUSION: Although the quality of consultation appears to be high for both SCEN physicians and other consultants, the SCEN project further contributed to the quality of consultation. Since GPs attach importance to judgement of SCEN physician and have the intention to use it in future, and the quality of consultation stays high over time, this project is expected to maintain its value.

Terminal sedation and euthanasia: a comparison of clinical practices.

BACKGROUND: An important issue in the debate about terminal sedation is the extent to which it differs from euthanasia. We studied clinical differences and similarities between both practices in the Netherlands. METHODS: Personal interviews were held with a nationwide stratified sample of 410 physicians (response rate, 85%) about the most recent cases in which they used terminal sedation, defined as administering drugs to keep the patient continuously in deep sedation or coma until death without giving artificial nutrition or hydration (n = 211), or performed euthanasia, defined as administering a lethal drug at the request of a patient with the explicit intention to hasten death (n = 123). We compared characteristics of the patients, the decision-making process, and medical care of both practices. RESULTS: Terminal sedation and euthanasia both mostly concerned patients with cancer. Patients receiving terminal sedation were more often anxious (37%) and confused (24%) than patients receiving euthanasia (15% and 2%, respectively). Euthanasia requests were typically related to loss of dignity and a sense of suffering without improving, whereas requesting terminal sedation was more often related to severe pain. Physicians applying terminal sedation estimated that the patient's life had been shortened by more than 1 week in 27% of cases, compared with 73% in euthanasia cases. CONCLUSIONS: Terminal sedation and euthanasia both are often applied to address severe suffering in terminally ill patients. However, terminal sedation is typically used to address severe physical and psychological suffering in dying patients, whereas perceived loss of dignity during the last phase of life is a major problem for patients requesting euthanasia.

European public acceptance of euthanasia: socio-demographic and cultural factors associated with the acceptance of euthanasia in 33 European countries.

In many European countries, the last decade has been marked by an increasing debate about the acceptability and regulation of euthanasia and other end-of-life decisions in medical practice. Growing public sensibility to a 'right to die' for terminally ill patients has been one of the main constituents of these debates. Within this context, we sought to describe and compare acceptance of euthanasia among the general public in 33 European countries. We used the European Values Study data of 1999-2000 with a total of 41125 respondents (63% response rate) in 33 European countries. The main outcome measure concerned the acceptance of euthanasia (defined as 'terminating the life of the incurably sick', rated on a scale from 1 to 10). Results showed that the acceptance of euthanasia tended to be high in some countries (e.g. the Netherlands, Denmark, France, Sweden), while a markedly low acceptance was found in others (e.g. Romania, Malta and Turkey). A multivariate ordinal regression showed that weaker religious belief was the most important factor associated with a higher acceptance; however, there were also socio-demographic differences: younger cohorts, people from non-manual social classes, and people with a higher educational level tended to have a higher acceptance of euthanasia. While religious belief, socio-demographic factors, and also moral values (i.e. the belief in the right to self-determination) could largely explain the differences between countries, our findings suggest that perceptions regarding euthanasia are probably also influenced by national traditions and history (e.g. Germany). Thus, we demonstrated clear cross-national differences with regard to the acceptance of euthanasia, which can serve as an important basis for further debate and research in the specific countries.

Predictors of survival in nursing home patients with severe dementia in whom artificial nutrition and hydration are [corrected] forgone.

BACKGROUND: To investigate the characteristics of patients in whom artificial nutrition and hydration (ANH) is forgone, duration of survival after the decision and factors that are associated with duration of survival. METHODS: Observational study based on written questionnaires in 32 Dutch nursing homes. Of 178 nursing home patients with dementia, their treating nursing home physician (NHP) filled in a questionnaire directly after the decision was made to forgo ANH. The maximum follow-up was 6 weeks. Cox proportional hazards analysis was used to determine predictors of survival. RESULTS: Decisions to forgo ANH in Dutch nursing homes were made most often in patients with severe dementia who also had an acute illness. More than half the patients (59%) died within 1 week after the decision. Patients with dyspnea and/or apathy were more likely to die during follow-up than patients without these symptoms. Patients who were considered more severely ill by the NHP were more likely to die than those who were considered less severely ill. The presence of restlessness indicated a higher chance of survival. CONCLUSIONS: The clinical judgment of the NHP of the severity of illness appeared to be a strong predictor of patient survival. NHPs should not rely solely on their clinical judgment concerning survival, but they should also consider the presence or absence of dyspnea, apathy and restlessness.

Does prenatal screening influence anxiety levels of pregnant women? A longitudinal randomised controlled trial.

OBJECTIVES: Questions addressed are: (1) Does offering prenatal screening increase anxiety? (2) Does receiving a negative screening result make women less anxious and does a positive screening result make women more anxious? (3) What are the long-term consequences on anxiety of offering screening and receiving a screening result? METHODS: Women were offered prenatal screening or no screening in a randomised controlled trial. State anxiety (STAI) and child-related anxiety (PRAQ-R) were measured. Questionnaires were filled in before prenatal screening was offered (T1), after the offer (T2), after the test result (T3), and in the third trimester of pregnancy (T4). RESULTS: Child-related anxiety levels were higher in women who chose to be screened compared to women who declined screening. Offering prenatal screening did not lead to increased anxiety levels. General anxiety increased in positively screened women, but decreased later in pregnancy. Women who were negatively screened or declined screening scored lower than the control group. CONCLUSION: For most women, offering prenatal screening and receiving the test result do not adversely affect anxiety. Giving pregnant women a choice to have prenatal screening done seems to have a small favourable effect on general feelings of anxiety.

Problems eliciting cues in SEIQoL-DW: quality of life areas in small-cell lung cancer patients.

The Schedule of Individual Quality of Life - Direct Weighting (SEIQoL-DW) is an individualized approach in the measurement of quality of life in which patients can choose, value and weight five areas that they consider important for their quality of life. Although a number of studies have reported on the feasibility of the administration of the instrument, little is known about how patients choose and define these five areas, the so-called 'cues'. This article describes problems in the elicitation of cues experienced in a qualitative, exploratory study among small-cell lung cancer patients (n = 31) in the Netherlands. Cues originate from patient-interviewer interaction which is best described as an area of tension between the patient's answers and the instrument instructions. As a result, the interviewer may inadvertently introduce bias while attempting to elicit cues, ultimately affecting patients' SEIQoL-DW measures. In order to prevent possible unnoticed interviewer bias special attention should be paid to the interviewer behaviour. Methods to record the meaning of cues should be considered. More research is needed in order to investigate differences in nominating cues with and without the use of the prompt list.

Requests to forgo potentially life-prolonging treatment and to hasten death in terminally ill cancer patients: a prospective study.

This study investigates the background and evolution of requests to forgo treatment and hasten death in terminally ill cancer patients. Physicians participating in a nationwide study on end-of-life decision making were asked whether they were treating a terminally ill cancer patient whose life expectancy was longer than 1 week but no longer than 3 months and who they would continue to treat until the patient's death. Of the 120 physicians who had a patient who met the inclusion criteria, 85 (70.8%) completed a questionnaire each month until the patient's death. The questionnaire provided information on the patient's symptoms, concerns, and requests involving end-of-life decisions. Most patients suffered from cancer of the gastrointestinal tract or the respiratory system, and 66% died within 2 months of the initial interview. The prevalence of requests involving end-of-life decisions increased during the last 3 months of a patient's life. The evolution of a request was especially related to an increase in the number of severe symptoms and concerns. Requests to forgo treatment were related to general weakness, whereas loss of dignity was a major reason for requests to hasten death. Physical suffering alone appeared to lead to less drastic requests than suffering blended by concerns and psychological problems leading to requests for hastened death. The results emphasize the importance of gaining insight into the patients' suffering to provide meaningful assistance.

Continuous deep sedation: physicians' experiences in six European countries.

Continuous deep sedation (CDS) is sometimes used to treat refractory symptoms in terminally ill patients. The aim of this paper was to estimate the frequency and characteristics of CDS in six European countries: Belgium, Denmark, Italy, The Netherlands, Sweden, and Switzerland. Deaths reported to death registries were sampled and the reporting doctors received a mailed questionnaire about the medical decision making that preceded the death of the patient. The total number of deaths studied was 20,480. The response rate ranged between 44% (Italy) and 75% (The Netherlands). Of all deaths, CDS was applied in 2.5% in Denmark and up to 8.5% in Italy. Of all patients receiving CDS, 35% (Italy) and up to 64% (Denmark and The Netherlands) did not receive artificial nutrition or hydration. Patients who received CDS were more often male, younger than 80 years old, more likely to have had cancer, and died more often in a hospital compared to nonsudden deaths without CDS. The high variability of frequency and characteristics of CDS in the studied European countries points out the importance of medical education and scientific debate on this issue.

Drugs used to alleviate symptoms with life shortening as a possible side effect: end-of-life care in six European countries.

We investigated the drugs used in the alleviation of pain and symptoms (APS) with a possible life-shortening side effect in six European countries' end-of-life care. We sent mail questionnaires to physicians who signed a representative sample of death certificates in each country. APS with a possible life-shortening effect occurred from 19% of all deaths in Italy to 26% in Denmark. Physicians usually administered opioids (from 76% of APS cases in Italy to 96% in The Netherlands), but the type of opioids and administration practice differed markedly between countries. The doses of opioids given in the last 24 hours also varied significantly and were usually lower than 300 mg oral morphine equivalent (from 83% of cases in Belgium to 93% in Sweden). The highly variable results bring into question whether existing guidelines for pain relief were applied appropriately and to what extent unfounded concerns about the possible life-shortening effect of opioids resulted in less than optimal symptom management in end-of-life care.

Predicted survival vs. actual survival in terminally ill noncancer patients in Dutch nursing homes.

Studies on the prediction of survival have mainly focused on hospital and hospice patients suffering from cancer. The aim of this study was to describe the predicted vs. the actual survival in terminally ill, mainly noncancer patients in Dutch nursing homes (NHs). A prospective cohort study was conducted in 16 NHs representative for The Netherlands. A total of 515 NH patients with a maximum life expectancy of 6 weeks, as assessed by an NH physician, were included. NH physicians were accurate in more than 90% of their prognoses for terminally ill--mainly noncancer--NH patients, when death occurred within 7 days. For a longer period of time, their predictions became inaccurate. In the category of patients who were expected to die within 8-21 days, predictions were accurate in 16.0%, and in the category of patients expected to die within 22-42 days, this was 13.0%. Predictions in these categories were mainly optimistic (patient died earlier) in 68.6% and 52.2%, respectively. The findings of this study suggest that accurate prediction of survival of (mainly) noncancer patients in NHs is only possible when death is imminent and seems to be dependent on an intimate knowledge of patients. Prognostication over a longer period of time tends to be less accurate, and, therefore, continues to be a challenging task for NH physicians.

Requests for euthanasia and physician-assisted suicide and the availability and application of palliative options.

OBJECTIVE: This study investigated the palliative options available when a patient requested euthanasia or physician-assisted suicide (EAS), the extent to which the options were applied, and changes in the patient's wishes. METHODS: In an observational study, 3614 general practitioners (GPs) filled in a questionnaire and described their most recent request for EAS (if any) (n = 1,681). RESULTS: Palliative options were still available in 25% of cases. In these cases options were applied in 63%; in 46% of these cases patients withdrew their request. Medication other than antibiotics, which was most frequently mentioned as a palliative option (67%), and applied most frequently (79%), together with radiotherapy, most frequently resulted in patients withdrawing their request. SIGNIFICANCE OF RESULTS: GPs include the availability of palliative options in their decision making when considering EAS. The fact that not all options are applied or, if applied, the patient persists in the request is related to autonomy of the patient, the burden on the patient, and medical futility of the option.

Physicians' opinions on palliative care and euthanasia in the Netherlands.

BACKGROUND: In recent decades significant developments in end-of-life care have taken place in The Netherlands. There has been more attention for palliative care and alongside the practice of euthanasia has been regulated. OBJECTIVE: The aim of this paper is to describe the opinions of physicians with regard to the relationship between palliative care and euthanasia, and determinants of these opinions. DESIGN: Cross-sectional. SETTING/SUBJECTS: Representative samples of physicians (n = 410), relatives of patients who died after euthanasia and physician-assisted suicide (EAS; n = 87), and members of the Euthanasia Review Committees (ERCs; n = 35). MEASUREMENTS: Structured interviews with physicians and relatives of patients, and a written questionnaire for the members of the ERCs. RESULTS: Approximately half of the physicians disagreed and one third agreed with statements describing the quality of palliative care in The Netherlands as suboptimal and describing the expertise of physicians with regard to palliative care as insufficient. Almost two thirds of the physicians disagreed with the suggestion that adequate treatment of pain and terminal care make euthanasia redundant. Having a religious belief, being a nursing home physician or a clinical specialist, never having performed euthanasia, and not wanting to perform euthanasia were related to the belief that adequate treatment of pain and terminal care could make euthanasia redundant. CONCLUSION: The study results indicate that most physicians in The Netherlands are not convinced that palliative care can always alleviate all suffering at the end of life and believe that euthanasia could be appropriate in some cases.

Preferences of the Dutch general public for a good death and associations with attitudes towards end-of-life decision-making.

BACKGROUND: Euthanasia and other end-of-life decisions are acceptable to the large majority of the Dutch public. Insight in the relationships of such acceptance, with characteristics considered important for a 'good death', may contribute to the understanding of this liberal attitude. METHOD: Questionnaires were mailed to 1777 members of the Dutch public (response: 78%), containing questions relating to a good death, attitudes towards euthanasia, terminal sedation and increasing morphine, and demographics. Associations between characteristics of a good death and attitudes towards these end-of-life decisions were analysed. FINDINGS: Characteristics that were considered important for a good death were: the possibility to say goodbye to loved ones (94%), dying with dignity (92%), being able to decide about end-of-life care (88%), and dying free of pain (87%). Acceptance of euthanasia, terminal sedation and increasing morphine were related to the wish to have a dignified death, and with concerns about burdening relatives with terminal care. Acceptance of euthanasia was also associated with the wish to be able to decide about medical end-of-life treatments and about the moment of death. INTERPRETATION: Besides saying farewell and dying pain free and with dignity, many members of the Dutch public consider values of control and maintenance of independence as important for a good death.
