[Legal regulation of special medical procedures].

Physicians in The Netherlands largely determine amongst themselves how they treat patients, whereas statutory regulations mostly concern indirect matters, such as qualifications of the treating persons, quality of care and patients' rights. Special items of service are currently reserved for special institutions. When the new Special Medical Services Act is passed, the minister is empowered to prohibit items of service if he/she considers these undesirable for social, ethical or legal reasons. More discussion is needed before such sensitive matters are to be regulated by law.

[International developments in the field of patient rights].

Patients' rights in Europe are becoming more and more similar. International agreements influence this development. New are the 'Declaration on the promotion of patients' rights in Europe' drawn up by the Regional Office for Europe of the WHO and adopted by a special European Consultation in 1994, and the draft of a 'Convention for the protection of human rights and dignity of the human being with regard to the application of biology and medicine' (Convention on Human Rights and Biomedicine of the Council of Europe). The WHO-declaration has also influenced the "Declaration of the rights of patients' of the World Medical Association in 1995.

[The use of drugs for euthanasia and assisted suicide in family practice].

An exploratory, descriptive, retrospective study was carried out concerning the use of means for euthanasia or assisted suicide, primarily regarding the period 1986-1989. Data were collected via an anonymous written inquiry among a random sample of family physicians in North Holland (n = 521) and family physicians in the rest of the Netherlands (n = 521). The inquiry contained among others questions about the last case they had encountered. In addition, police reports of euthanasia or assisted suicide administered by family physicians in North Holland (n = 263) were analysed. The response to the inquiry was 67%; (non-respondents did not differ from respondents): 388 cases could be analysed. The use of euthanatics by family physicians in North Holland and those in the rest of the Netherlands was identical. More than 40 different euthanatics were used, most of them incidentally. The most frequently used (combination of) means were a benzodiazepine with a neuromuscular relaxant (23%), a barbiturate with a neuromuscular relaxant (20%), barbiturates (15%) and opioids (12%). Most euthanatics were given intravenously (61%, of which 5% by infusion), orally 21%, intramuscularly 12%, rectally 3% and subcutaneously 2%. The quantities applied varied greatly. The average length of time from the start of the procedure till decrease was 3.8 hours (less than or equal to 1 minute-72 hours). In 12% of the cases complications or unintended effects were reported. Comparison of inquiry and police reports showed some differences.(ABSTRACT TRUNCATED AT 250 WORDS)

Euthanasia and assisted suicide. I. How often is it practised by family doctors in The Netherlands?

A survey was conducted among family doctors to determine the frequency with which they were requested to administer euthanasia or assist in suicide, and how often they actually applied these procedures. Two random samples (in each n = 521) were taken from the population of Dutch family doctors (n = 6300) and requested to complete an anonymous questionnaire. The response was 67%. The entire body of Dutch family doctors practices euthanasia or assisted suicide about 2000 times per annum; 48% have never engaged in these practices. An average of 40% of all requests are complied with. We conclude that far fewer family doctors are involved in euthanasia and assisted suicide than was previously supposed. Euthanasia or assisted suicide was administered to 1 in 25 persons who died in their own homes.

Euthanasia and assisted suicide. II. Do Dutch family doctors act prudently?

We conducted a survey among two random samples of Dutch doctors in order to determine whether they acted prudently with regard to euthanasia and assisted suicide. The doctors completed an anonymous questionnaire and those who at one time or another had applied euthanasia or assisted suicide (52%) were asked about several aspects of the requirements for prudent practice. 'Pointless suffering' was the most important and most common reason for requesting euthanasia or assisted suicide; 'pain' was rarely the most important reason. In 7% of the cases alternative forms of treatment were still available; these were hardly ever therapeutic. A total of 12% of the doctors had applied euthanasia or assisted suicide without having had any kind of consultation or discussion with a colleague, a nurse or any other health care professional; 26% had not issued a certificate testifying to death from natural causes. We conclude that some of the family doctors do not observe the procedural requirements, but that the majority satisfies the material requirements for prudent practice.

[Euthanasia and assisted suicide by physicians in the home situation. I. Diagnoses, age and sex of patients].

In order to map out morbidity, age and sex of patients with whom family doctors participated in euthanasia or assisted suicide, an exploratory, descriptive, retrospective study was carried out primarily regarding the period 1986-1989. Data were collected via an anonymous written injury among an at random sample of family doctors in North Holland (n = 521), and family doctors in the rest of the Netherlands (n = 521). In addition, police reports of euthanasia/assisted suicide administered by family doctors in North Holland (n = 263) were analysed. The inquiry included among others questions about the last case doctors had encountered. Diagnoses were classified according to the ICD-9. The results were compared with compiled mortality data relating to persons who died in their own homes. Correlations and differences were analysed by means of the chi2-test. The response to the inquiry was 67% (non-responders did not otherwise differ from responders): 228 (North Holland), 160 (rest of the Netherlands) and 263 (police reports) cases could be analysed. Of the patients, 85% suffered from a malignant neoplasm. The average age at which euthanasia or assisted suicide was practised was 63.4 years (men) and 66.1 years (women). Under the age of 30 and above 85 euthanasia or assisted suicide was administered only rarely. Proportionally these procedures were applied to the same extent to men as to women. In about 20% of the cases an important secondary diagnosis was present. In conclusion, it is especially the malignant neoplasms that cause such suffering that euthanasia or assisted suicide are practised. The average age at which they are applied is considerably lower than that of the total of people who die in their own homes.(ABSTRACT TRUNCATED AT 250 WORDS)

[Euthanasia and assisted suicide by physicians in the home situation. 2. Suffering of the patients].

In order to assess the suffering of patients who died at home and with whom family doctors participated in euthanasia or assisted suicide, an exploratory, descriptive, retrospective study was carried out regarding primarily the period 1986-1989. Data were collected via anonymous written inquiry among an at random sample of family doctors in North Holland (n = 521), and family doctors in the rest of the Netherlands (n = 521). With reference to the last case of euthanasia or assisted suicide they had encountered questions were included about physical and emotional suffering, signs and symptoms and life expectation. Correlations and differences were analysed by means of the chi2-test. The response to the inquiry was 67% (non-responders did not otherwise differ from responders): 228 (North Holland), 160 (rest of the Netherlands) cases could be analysed. Most patients suffered physically as well as emotionally. The most frequently mentioned aspect was 'general weakness or tiredness'. Also 'dependence or being in need of help', loss of dignity, humiliation' and 'pain' were often present to a (very) large extent. At the time the procedure was carried out the life expectation in almost two-thirds of the cases was less than 2 weeks; in 10% of the cases it was more than 3 months. For several reasons, this investigation reduces the possibilities of extrapolation. Further investigation is necessary to determine whether this picture of suffering is specific of this category of patients.
