Screening technology, citizens’ autonomy and public health

The use of technologies to screen for risk of non-communicable disease in asymptomatic people sits on the boundary between public health and clinical health care. This leaves open the question of whether principles from clinical ethics or public health ethics are more directly applicable to evaluating the offer and provision of such services. I will argue that, in the case of screening for non-communicable diseases, screening is only weakly public. If this is accepted, then the central principle from clinical ethics of respecting and/or supporting autonomy will become normatively relevant. What this requires, however, depends on how autonomy is conceptualised. Using the work of Catriona Mackenzie, I will argue that a unidimensional, decisional conception of autonomy is insufficient for the task of ensuring that screening technologies are offered to citizens in a justified way. A multi-dimensional, relational conception of autonomy encourages attention to a wider range of normatively relevant concerns, and is more appropriately restrictive of offers of technologically-driven screening services.


Stacy’s background is in public health, and her research focuses on public health ethics. She is currently working on: normative dimensions of screening, especially cancer screening; overdiagnosis and too much medicine; de-prescribing in older people; relational conceptions of paternalism; normative dimensions of health promotion; methodology for empirical bioethics; and deliberative methods. Stacy is a qualitative researcher, and supervises a range of empirical public health ethics projects. She has a particular interest and expertise in grounded theory. She is currently a chief investigator in Wiser Healthcare, an NHMRC-funded collaboration to reduce overdiagnosis and overtreatment ( She tweets sporadically @stacymcarter.

About the Association

The Australasian Association of Bioethics and Health Law (AABHL) was formed in 2009.

It encourages open discussion and debate on a range of bioethical issues, providing a place where people can ask difficult questions about ideas and practices associated with health and illness, biomedical research and human values.

The AABHL seeks to foster a distinctive Australasian voice in bioethics, and provide opportunities for international engagement through its membership, journal and conferences.

Members come from all the contributing humanities, social science and science disciplines that make up contemporary bioethics.

Many members have cross-disciplinary interests and all seek to broaden the dialogues in which all members of the wider community ultimately have an interest.

The AABHL is a supportive, creative and challenging community that provides a rich source of continuing academic refreshment and renewal.
