As the severity of dementia increases the decision-making capacity of a person with dementia has been shown to decrease. The person with dementia will eventually reach a stage where they are no longer able to make decisions for themselves. At this point, major decisions (e.g. moving into residential care, being transferred to hospital from residential care, consenting to an operation, and deciding on end-of-life care) become the responsibility of someone else, typically a family member or a legally appointed surrogate.

The research reported here explored: how surrogate decision-makers make decisions on behalf of a person with dementia (that is respecting the person’s precedent autonomy or determining their current best interests); whether they feel they need support in making these decisions and; if so, what types of support and means of support delivery are preferred.

The study was informed by Grounded Theory Methodology. Thirty-four semi-structured interviews were undertaken with surrogate decision-makers of a person with dementia (either legally appointed or else recognised as the ‘person responsible’) who had already made a major life decision on behalf of a person with dementia.

A mix of surrogate decision-making methods was reported, and included both the substituted judgement and the best interest standard, which were applied to a range of situations in which a major decision had been made.

Surrogate decision-makers use a variety of ways to make decisions on behalf of a person with dementia most often in the absence of an advance care directive. The research highlighted a need for greater support to assist surrogate decision-makers through what is often a complex and confronting process. This presentation will also discuss recommendations on how surrogate decision-makers of people with dementia can be better supported in their role.

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.
