In a questionnaire study on organ allocation 348 students of medicine (102) and economics (246) at the universities of Halle (114 students) and Hannover (234 students) responded to questions concerning their basic attitudes toward alternative criteria of organ allocation. Medical criteria were widely accepted by the respondents. Considerations concerning the patient's value to society were seen as being of minor importance. With respect to reciprocity, we could detect a high share of respondents who would favor former living donors and discriminate (...) against murderers. Among considerations of fairness, the criterion of waiting time gained the highest support. Furthermore, majorities favored the view that health-compromising behavior and differences in age should play a role. Economic considerations were strongly rejected as criteria of organ allocation.
