Autonomy plays a central role in bioethics, but there is no consensus as to how we should understand this concept. This paper critically considers three different conceptions of autonomy: the default conception prevalent in bioethics literature; a broader procedural account of autonomy drawing on moral philosophical approaches; and a substantive, perfectionist account. Building on Rebecca Walker's critique of the default conception of autonomy, we will argue that a substantive, perfectionist approach both fulfils Walker's criteria for a conception of autonomy in bioethics and lends itself to application in practical scenarios. In so doing, we draw on scenarios from genomic medicine to show that a substantive, perfectionist approach not only offers a more conceptually adequate understanding of autonomy in more complex cases, but also lends itself to practical application by helping health professionals identify how they can maximize people's capacity to exercise their autonomy.
Reproductive genetic carrier screening (RCS) is increasingly being offered more widely, including to people with no family history or otherwise elevated chance of having a baby with a genetic condition. There are valid reasons to reject a prevention-focused public health ethics approach to such screening programs. Rejecting the prevention paradigm in this context has led to an emphasis on more individually-focused values of freedom of choice and fostering reproductive autonomy in RCS. We argue, however, that population-wide RCS has sufficient features in common with other public health screening programs that it becomes important also to attend to its public health implications. Not doing so constitutes a failure to address the social conditions that significantly affect people’s capacity to exercise their reproductive autonomy. We discuss how a public health ethics approach to RCS is broader in focus than prevention. We also show that additional values inherent to ethical public health—such as equity and solidarity—are essential to underpin and inform the aims and implementation of reproductive carrier screening programs.
Background: Biobanks provide an important foundation for genomic and personalised medicine. In order to enhance their scientific power and scope, they are increasingly becoming part of national or international networks. Public trust is essential in fostering public engagement, encouraging donation to, and facilitating public funding for biobanks. Globalisation and networking of biobanking may challenge this trust. Methods: We report the results of an Australian study examining public attitudes to the networking and globalisation of biobanks. The study used quantitative and qualitative methods in conjunction with bioethical analysis in order to determine factors that may contribute to, and threaten, trust. Results: Our results indicate a generally high level of trust in biobanks and in medical research more broadly. Key factors that can reduce perceived trustworthiness of biobanks are commercialisation and involvement in global networking. Conclusions: We conclude that robust ethical oversight and governance standards can both promote trust in global biobanking and ensure that this trust is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
