Physicians' experiences with end-of-life decision-making: Survey in 6 European countries and Australia
BMC Medicine volume 6, Article number: 4 (2008)
In this study we investigated (a) to what extent physicians have experience with performing a range of end-of-life decisions (ELDs), (b) if they have no experience with performing an ELD, would they be willing to do so under certain conditions and (c) which background characteristics are associated with having experience with/or being willing to make such ELDs.
An anonymous questionnaire was sent to 16,486 physicians from specialities in which death is common: Australia, Belgium, Denmark, Italy, the Netherlands, Sweden and Switzerland.
The response rate differed between countries (39–68%). The experience of foregoing life-sustaining treatment ranged between 37% and 86%: intensifying the alleviation of pain or other symptoms while taking into account possible hastening of death between 57% and 95%, and experience with deep sedation until death between 12% and 46%. Receiving a request for hastening death differed between 34% and 71%, and intentionally hastening death on the explicit request of a patient between 1% and 56%.
There are differences between countries in experiences with ELDs, in willingness to perform ELDs and in receiving requests for euthanasia or physician-assisted suicide. Foregoing treatment and intensifying alleviation of pain and symptoms are practiced and accepted by most physicians in all countries. Physicians with training in palliative care are more inclined to perform ELDs, as are those who attend to higher numbers of terminal patients. Thus, this seems not to be only a matter of opportunity, but also a matter of attitude.
Postponing death is not always a self-evident goal of medicine. Other goals have also to guide medical decision-making at the end of life, such as improving the quality of life of patients and their families through the prevention and relief of suffering, even if this might hasten death . End-of-life decisions (ELDs) include decisions about withholding or withdrawing potentially life-prolonging treatment and about alleviation of pain or other symptoms with a possible life-shortening effect. In some countries it is also permissible to make decisions about euthanasia or physician-assisted suicide (EAS), defined as the administration, prescription or supply of drugs to end life at the patient's explicit request.
ELDs occur throughout the world, albeit at different rates for different actions [2–14]. In the first EURELD study, which presented data on 20,480 deaths in six European countries (Belgium, Denmark, Italy, the Netherlands, Sweden and Switzerland), physicians reported that death was preceded by an ELD in 23% (for Italy) to 51% (for Switzerland) of all deaths . Most frequently it concerned alleviation of pain and symptoms (19–26%) and non-treatment decisions (4–28%). The treatment most frequently forgone was nutrition or hydration and medication (62–71%) . Continuous deep sedation was provided in 2.5% of all deaths in Denmark and up to 8.5% in Italy. In 35% (Italy) to 64% (Denmark and The Netherlands) of deaths a decision was made to withhold or withdraw artificial nutrition or hydration . EAS varied from 1% or less in Denmark, Italy, Sweden and Switzerland, to 1.82% in Belgium and 3.40% in the Netherlands .
A survey among physicians in Australia in 1996 used similar questions to the EURELD study described above, although using a different method. It was found that 31% of all Australian deaths were preceded by alleviation of pain and symptoms with possible life-shortening effect. Death was preceded by foregoing treatment in 29% of cases, and administration of drugs with the explicit intention of hastening death occurred in 5.3% (see ).
These studies looked at the frequency of ELDs in patient deaths. Few studies have investigated how much experience physicians have with performing ELDs. Such research could not only illuminate the willingness of physicians to perform ELDs, but also possible associations between physicians' background characteristics, attitudes and experience with ELDs. For the second EURELD study, Australia joined the consortium to participate in such a survey among physicians. The purpose of the present paper is to report (a) to what extent do physicians in the seven countries have experience with performing a range of ELDs, (b) if they have no experience with performing an ELD, would they be willing to do so under certain conditions and (c) which background characteristics are associated with having experience with/or being willing to make such ELDs. The specific questions are presented in Additional file 1.
In each country, a random sample of 300 physicians was drawn from the professional registers of specialities in which physicians frequently attend to dying patients: these included anaesthesiology, general practice, geriatrics, gynaecology, internal medicine, neurology, nursing home medicine (the Netherlands only), oncology (not a separate speciality in the Netherlands), pulmonology and surgery. In Italy the sampling was drawn from hospital and general practice registers. When there were less than 300 physicians working in a speciality, all specialists were included in the sample. In Italy general practitioners were over-sampled. The number of questionnaires sent out in the end of 2002 varied from 1870 in Denmark to 3873 in Italy. In addition to background characteristics and palliative care education, physicians were asked about: their attitudes, intended behaviour and practices concerning end-of-life care; communication with terminally ill competent patients and their families; and experiences of making ELDs. The ELDs were described as neutrally and factually as possible in order to avoid differences in interpretation. EAS, for instance, were formulated as 'administering, prescribing or supplying drugs with the explicit intention of hastening the end of life on the explicit request of a patient'. The data of all countries were combined in a common database to ensure identical coding and analysis procedures. When presenting frequencies, weighting factors were used to correct for the different sampling fractions and response percentages in the different strata. Detailed inclusion criteria and methods have previously been reported .
For each country, the percentage of physicians who had (a) performed an ELD, (b) never performed an ELD, but would be willing to do so under certain conditions, (c) never performed an ELD and would never do so and (d) ever received an explicit request from a patient to administer, prescribe or supply drugs with the explicit intention of hastening death are presented.
Possible predictors for experiences with ELDs were analysed by multivariate and multinomial logistic regressions. Having performed an ELD versus never having performed an ELD (and willingness yes or no) was analysed using a multiple logistic regression per ELD entering sex (M, F), age (≤50, >50), palliative care training (yes, no), number of terminal patients in 12 months (≤5, >5), religion (religion (very) important, philosophy of life (very) important, religion and philosophy of life not important), attitude on right to decide to hasten death (strongly agree, agree, neutral, disagree, strongly disagree) and attitude on aiming at preserving life (strongly agree, agree, neutral, disagree, strongly disagree); these factors were controlled for country and clinical speciality. The same factors per ELD were used in order to make comparisons between ELDs possible. In addition, a multivariate logistic regression was performed in order to investigate the importance of clinical speciality on experiences with ELDs, adjusted for country. Finally, a multinomial logistic regression was used to compare the reference group of physicians with experience of EAS, with two groups of physicians who had never performed EAS: (1) physicians willing to perform EAS and (2) physicians unwilling to do so. Independent variables were: ever received an explicit request for physician-assisted death (PAD) (yes/no)
As no patients were involved in the study and that answering of the questionnaire was voluntary and anonymous, assessment by an ethics review committee was not required except in Australia where ethics approval was given by the Human Research Ethical Review Committee of the University of Queensland.
Response rates were: Australia (AU) 53% (n = 1478), Belgium (BE) 58% (n = 1750), Denmark (DE) 68% (n = 1217), Italy (IT) 39% (n = 1508), the Netherlands (NL) 61% (n = 1275), Sweden (SE) 60% (n = 1514) and Switzerland (CH) 64% (n = 1397). Altogether 10,139 questionnaires were studied.
Frequencies of experience with the different ELDs, and willingness to perform if not performed yet, are presented in Table 1. Physicians in Italy had the lowest experience of foregoing life-sustaining treatment (37% versus 72–86%) and the highest intention of not doing so (24% versus 1–6%). In all countries a majority of physicians had intensified the alleviation of pain or other symptoms while taking into account possible hastening of death. For Australia, Belgium, Denmark and the Netherlands this was a very large majority (83–95%), while the percentage was somewhat smaller in Italy (57%), Sweden (64%) and Switzerland (71%). The group of physicians who would never be willing to alleviate pain and other symptoms by increasing medication to a level that risked hastening death was largest in Italy (17% versus 1–10%). Experience with deep sedation until death was lowest in Italy (12%) and highest in the Netherlands (46%). Physicians in the Netherlands had most experience with receiving a request for hastening death (71%), followed by physicians from Belgium (40%), Switzerland (37%), Australia (36%) and Denmark (34%). Intentionally hastening death on the explicit request of a patient was most common in the Netherlands (56%). In the other countries the percentage of physicians who would never be willing to do this varied from 36% in Belgium to 84% in Sweden. In Italy this question was not asked.
Different factors were important for experiences with ELDs (Table 2). Female physicians less frequently had experience with all ELDs than male physicians. Physicians aged over 50 had less experience than younger physicians with withholding or withdrawing treatment and intensifying pain or symptom medication which risked hastening death, while they had more experience with the other ELDs. Both having had training in palliative care and having attended more than five terminal patients in the last 12 months resulted in more experience with all ELDs. Religion being important for one's professional attitude was associated negatively with intensifying pain or symptom medication and hastening death on a patient's request. A non-religious philosophy being important for one's professional attitudes had the opposite effect. Being of the opinion that every person has a right to decide to hasten death was positively associated with experience with all ELDs except withholding or withdrawing treatment. Being of the opinion that physicians should always aim at preserving life was negatively associated with experience with all ELDs and most strongly with intentionally hastening death (odds ratio (OR) = 0.44) and withholding or withdrawing treatment (OR = 0.55).
Compared with general practitioners, gynaecologists, neurologists and surgeons seemed to have the lowest experience of most ELDs. Geriatricians (OR = 3.1), physicians in internal medicine (OR = 2.0), anaesthesiologists (OR = 1.9) and oncologists (OR = 1.4) had more experience with foregoing treatment than general practitioners. Oncologists and pulmonologists had more experience than general practitioners with all ELDs except hastening death on the explicit request of a patient. (Table 3).
Table 4 shows the results of a multinomial logistic regression aimed at identifying factors associated with (n)ever having hastened death among three groups: physicians who have performed this ELD, physicians who never did but would be willing to do so under certain conditions and physicians who never did and would never do so. Compared with physicians who had hastened death, physicians who would never do so were less likely to be over 50 years of age, to have had palliative care training, to have attended to more than five terminal patients in the last year, to have a non-religious philosophy of life and were also less likely to think that a person should have the right to decide whether or not to hasten their death; they were more likely to be female, to think that physicians always should aim at preserving the lives of their patient, that sufficient availability of high-quality palliative care prevents almost all requests for euthanasia, that permitting hastening death on the explicit request of a patient will lead to hastening death without a request and will harm the relationship between patients and physicians. Looking at the physicians who never hastened death on the request of a patient but would be willing to do so under certain conditions shows a similar pattern, albeit that the associations are less strong.
There are differences between physicians in the countries under study regarding experiences with ELDs, willingness to perform ELDs and frequency with which requests for EAS are received. In general, physicians in Italy have least experience with these issues, followed at some distance by Sweden, while physicians in the Netherlands have the most experience. Foregoing treatment and alleviation of pain and symptoms by intensifying medication to a level, which risks hastening death are accepted by physicians in all countries, since only a small minority have never performed them and would never do so. These are also the ELDs that were found to occur most frequently in the first EURELD (death certificate) study.
The main strength of this study was that the same methodology was used in all countries, which made it possible to compare countries. We are not aware of any other international surveys on this subject. A limitation of this study is that it was retrospective, which may have resulted in recall bias.
A number of the authors currently work or research in end-of-life areas. Our experience suggests that since physicians sent in this questionnaire in 2003, the question arises whether there are reasons to believe that physicians' practices have changed since then. In the Netherlands, ELDs have been studied extensively since then . It showed that the practice of ELDs remained stable over the years, with the exception of euthanasia, which occurred less frequently in 2005 compared with 2001. In Belgium things may have changed, as the euthanasia law is only now in full effect. Recent data obtained by another method than the death certificate method suggest that there is more euthanasia in Flanders than before, 1.6% in 2005–2006 instead of 0.3%. There is also a rise in the total number of potentially life-shortening ELDs, from 38% to 50% . The general increase may of course be reflected in physicians' experiences with ELDs.
Although reasons for the differences between countries can only be speculative, in the Netherlands the reason that physicians have more experience with ELDs may be a more liberal tradition and higher respect for patient autonomy. A religious influence is not evident, as Belgium, with a substantial Catholic population, has the second highest experience with ELD, and Sweden, which is a Protestant country, has the lowest together with Italy, a Catholic country. Denmark, which also has a Protestant population, is closest to Belgium. The results do indicate that a non-religious philosophy of life seems to increase the willingness to perform EAS, possibly out of respect for patient autonomy. Cohen et al  have studied life-stance and general attitudes towards ELDs in more detail. They found that teachings of religious bodies indeed have an influence on end-of-life decision-making, but are certainly not blankly accepted by physicians. The influence of doctrinal teachings is somewhat clearer on general attitudes towards end-of-life decision-making. It can perhaps be explained by the fact that most people embrace (theistic) belief not in strict metaphysical terms, but in non-imperative ways, allowing for adaptation to particular situations, for instance to the needs and wishes of the dying and to considerations of humaneness.
Physicians can only perform EAS when a patient requests it. Physicians in all countries receive euthanasia requests, most often in the Netherlands, where physicians also have most experience with performing EAS.
The results show that physicians with training in palliative care are more inclined to make ELDs. While this may be expected for some of the ELDs, it is somewhat surprising for EAS. One hypothesis may be that palliative care physicians develop a higher attention to patients' wishes. Further research is needed to clarify and explain this finding.
Furthermore, the findings indicate that the legislation and medical guidelines are reflected in physicians' experiences. In all countries, physicians had the highest experiences of non-treatment decisions and alleviation of pain and other symptoms with possible life-shortening effect: kinds of ELDs, which are legal in all participating countries. The fact that experiences of continuous deep sedation, which is legal in all countries, is relatively low, demonstrates that this ELD is more strongly influenced by situational factors such as uncontrollable pain and symptoms than by legal regulations. The different legal regulations concerning EAS are also reflected in physicians' experiences. Shortly before this study was performed, the Netherlands and Belgium changed their legislation, in 2001 and 2002, and now permit EAS under certain conditions. In the Netherlands EAS are regulated as two possible end-of-life options. In Belgium the law only regulates euthanasia. In both countries the patient involved must be a mentally competent adult when requesting help. Doctors can only proceed when they know the patient well enough to be able to assess whether their request for euthanasia is voluntary and well-considered, whether the patients' medical situation is without prospect of improvement and whether the individual's suffering is unbearable. The ability to refuse a request for euthanasia guarantees a doctor's freedom of conscience in both countries . Whether this has influenced experiences and attitudes remains to be studied in Belgium. For the Netherlands, the evaluation of the euthanasia law showed that the incidence of EAS decreased from 2.8% in 2001 to 1.8% in 2005 (see ).
In Switzerland, assistance in suicide is allowed provided that the person seeking assistance has decisional capacity and the person assisting is not motivated by reasons of self-interest; euthanasia is forbidden in all circumstances. Experiences with ELDs can be associated with two types of factors. One is the opportunity the physician has for making ELDs. The second is the attitude of the physician towards questions about philosophy of life, e.g. whether people have a right to decide to hasten the end of life and whether physicians should always aim at preserving life. Older physicians may have been practising medicine longer and thereby have an increased chance of ever having performed an ELD. Further, the number of terminal patients attended to by the physician within a given time period varies from one speciality to another. However, since having had palliative care training is positively associated with having experience with all ELDs, independent of the number of terminal patients under the physician's care, this factor probably reflects an attitude. Female physicians have less experience with ELDs, which does not seem to be related to opportunity and attitude. A similar finding comes from Italy, where male anaesthesiologists had greater experience with foregoing treatment . However, the reason is not obvious and ought to be studied in the future.
In conclusion, there are differences between countries in experiences with ELDs, in willingness to perform ELDs and in receiving requests for EAS. Foregoing treatment and intensifying alleviation of pain and symptoms are practiced and accepted by most physicians in all countries. Physicians with training in palliative care are more inclined to perform ELDs, as are those who attend to higher numbers of terminal patients. Thus, this seems not to be only a matter of opportunity, but also a matter of attitude.
