[Attitudes on euthanasia and medical advance directives].
BACKGROUND: With regard to medical decisions and measures at the end of life, the values and attitudes of those concerned are crucial. However, they have hardly been taken into account so far in German empirical studies on euthanasia and medical advance directives. METHOD: Between October 2003 and May 2004, a mail survey of a representative group of internists, anaesthetists and general practitioners from Bavaria, Westphalia-Lippe and Thuringia was conducted. RESULTS: Of 1,557 mailed questionnaires 727 were returned (rate of returns: 46 %). The survey showed, high of appreciation for medical advance directives and, at the same, time scepticism regarding surrogate decision-making by legal guardians and authorized representatives. Furthermore, the survey revealed a considerable amount of uncertainty in the physicians about the application of certain measures at the end of life to the different forms of euthanasia. In practice, many physicians do not comprehend the juridical differentiation between (illegal) active and (legal) passive or indirect euthanasia. CONCLUSIONS: In training and further education more scope should be given to the reflection of medical decisions at the end of life. At the same time, the usual, partly counterintuitive legal definitions should be brought more into line with medical decision making, while taking into account developments in English speaking areas. A transdisciplinary discourse is indispensable for the development of medical ethical and legal justifications suitable as guidance for action.
