Methods

- case-specific questions
• Additional interviews:
- nursing home physicians (12)
- relatives of people with dementia (9)
Results (1) - questionnaire
• Prevalence
-
On average 33 pg-patients
-
One or two have an advance directive
-
Less than half (47%) of the directives include a request for
euthanasia
Results (2) - questionnaire
• Attitudes of physicians
Do you consider it possible you would, in the future, perform euthanasia on
a patient with dementia who has an advance euthanasia directive?
Yes

Other factors:
- in 13% of the cases the patient did not want euthanasia
- in 15% of the cases relatives of patients did not want euthanasia
Results (4) - interviews
• Relatives who do not want euthanasia
‘ My father, yes, he would have never wanted this for her of course, but to
give her an injection, so to speak of, well, that he didn’t want either, you
know’ [relative]
• Difficulties in determining the ‘suffering’
‘The patient expressed discomfort at times she was aware of her
deterioration or when things happened she didn’t like. At other times there
was no awareness and the patient seemed ‘content’’ [physician]
‘we actually had the feeling, that despite the fact that she became
demented, eh she could still enjoy many things. It wasn’t really someone
who ehm who was suffering’ [relative]
Results (5) - interviews
• Absense of actual wish
‘..a patient with dementia who has an advance euthanasia directive but
does not ask for it, for actual life-termination, you know, or does not
specifically expresses all sorts of death-wishes and consistently does that,
then I wouldn’t even think about it [euthanasia]’
• Policy of nursing home often restricts euthanasia
‘I have indicated that it is not possible for me to end madams life in case
her situation is stable and she does not ask for it herself, only because she
lives in a nursing home’ [physician]
‘Take care of madam as well as possible and relief complaints if they occur,
but not to push it to the limit’ [physician]
Results (6) - questionnaire
•
According to physicians in 63% of the cases relatives wanted a restricted policy of
treatment instead of euthanasia
•
In 93% of cases decisions were made not to start or withdraw one or more lifeprolonging treatment(s)

Conclusions
• Positive attitudes towards advance directives in general
• Advance (euthanasia) directives do not seem to achieve
what they intend to achieve
• Reluctance to perform euthanasia in cases of dementia
• Questions can be raised regarding the effectiveness of
advance directives of people with dementia
• Reconsider the role of advance (euthanasia) directives
