How do we decide the ethics of treatments that are not evidence based?

Recent issues of the Journal of Bioethical Inquiry have had several papers discussing the ethics of homeopathy. In this presentation I will argue that asking whether a treatment modality is ethical or not is unhelpful. Any treatment is always provided by a practitioner; homeopathic treatments are dispensed by homeopaths. It is well described that the placebo response applies to virtually all such therapeutic relationships and that there is sound evidence establishing the neurophysiological basis of this response. Conversely the assertion that conventional medical practice is evidence based does not bear up to examination with only between 6-15% of many guidelines being based on high level evidence. In particular there are many surgical procedures for which there is no good evidence, and for some, good evidence that the only benefit  is from the placebo response.

This paper will present a framework for considering whether any particular health practice can be seen as ethical and how we should respond to practitioners who are not part of the conventional medical world.

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.
