Background: Medical ethics is a central topic in the medical daily routine. Physicians have to make treatment decisions within the context of medical ethics every day. Therefore it is inevitable to train future doctors during their studies on topics concerning medical ethics to sensitize them adequately. The aim of this thesis is to inquire and investigate the attitudes of medicine students of the Medical University of Graz concerning selected aspects of medical ethics. Additionally, it should be explored of which importance medical ethics within their studies are.Methods: This master thesis is divided into a theoretical framework followed by an empirical part. Hence, the focus of the thesis lies on the conducted observation study. 327 students filled in a questionnaire concerning selected aspects of medical ethics between February and July 2014. The range of topics within the empirical part refers to decision-making at the end of life, biopolitics and eugenics, justice within the health system, patients autonomy and ethics education at university. The selected topics are going to be presented as an overview in the theoretical part in order to provide basic knowledge about the different parts. A second emphasis of the survey was put on authority measurements of students and the relation between attitudes and behavior. Results: Students showed a general agreement on active euthanasia (50,8 %), physician-assisted suicide (65,7 %) and passive euthanasia (95,1 %). However, it has to be noted that gender does not play any role in these findings. Religious and authoritarian students tend to be against life shortening steps of any kind. 89,3 % of the respondents attach importance to training on medical ethics within their studies. Apart from that 47 % think that courses on medical law are more important than courses on medical ethics. Conclusion: With regard to the field of tension of medical ethical decision-making it is crucial to encourage academic teaching in the field of medical ethics or rather to extent it, for a reflected handling in physicians daily routine. Hence, students consider focused training in this field to be desirable. Another emphasis should be put on medical law, because it seems that students show a factor of uncertainty concerning the legal framework.
