2 Acknowledgments My sincere thanks go to the families whose voices are characterised within this thesis. I cannot thank you enough for your courage and generosity in entrusting me to represent your experience. I must also acknowledge the many patients and families I have cared for who have taught me much about the human spirit, especially forgiveness, resilience and love. I have been exceptionally fortunate in my supervisors. My deepest thanks go to Professor Mary Cruickshank for her professional expertise, wisdom, kindness and continual belief in me. I am also extremely grateful to Dr Gylo (Julie) Hercelinskyj and Dr Kristen Ranse for their support, humour and care.

12 Glossary Death The Australian Law Reform Commission (1977) defined death as the a) irreversible cessation of all function of the brain of the person or b) irreversible cessation of circulation of blood in the body of the person. Deep hope This idea is drawn from palliative care literature. Deep hope is defined as: a layer of hope that underlies this experience and may continue to exist, or even thrive, during a time when the patient[and their family] has very few somethings left to hope for (Coulehan, 2011, p. 144). Empathic neutrality Patton (2002) uses this term to describe an interview technique whereby the interviewer uses a nonjudgemental approach which demonstrates attentiveness, openness, sensitivity, respect, awareness, and responsiveness (p. 40) to establish a vicarious understanding of the participant experience. Family Family was defined as those that self-select as family of the deceased, that are recognised as family in the naturalistic setting, and were involved in the family decision-making process. Consistent with realworld experiences, family may include people without a legally recognised relationship. Depending on jurisdictional clinical practices, these people may or may not be involved in the formal decision-making action of providing written consent for organ donation. Hope Hope Theory was defined by Snyder (2002) as the perceived capability to derive pathways to desired goals, and motivate oneself via agency thinking to use those pathways (p. 249). Moral Discernment A concept discussed by Christians (2005) that sees an unfolding alignment of a common moral understanding which takes place in the interaction and collaboration of the researcher with the researched. Christians (2005) argues this is a radical alternative to the individualism of modernity (p.155) and is an idea that aligns with the philosophical stance of this study. Trust The definition for trust used in this study combines rational and relational trust and is defined by Barber (1983) as social learned and social confirmed expectations that people have of each other, of the organisations and institutions in which they live, and the natural and moral social orders, that set the fundamental understandings of their lives (p. 28). xii

13 Abstract The therapeutic, social and economic benefits of organ transplantation are irrefutable; however, organ shortages contribute to avoidable patient deaths and burgeoning health care costs. This problem can be addressed by increasing family consent to deceased organ donation. There are high levels of community support for deceased organ donation in Australia and yet, almost fifty percent of families decline the request to donate. Increasing the number of families who agree to deceased organ donation is key to increasing national and international transplantation rates. The purpose of this study was to identify the major factors that influence a family to agree or decline deceased organ donation during the process of decision-making. The aims of the study were three-fold: to identify the key stages and the major influencers in the decisionmaking process; to determine if hope, deep hope and trust played a role in the decision, and to explore families perceptions of their decision-making experience. The study utilised an exploratory case study approach to examine the family decisionmaking process of deceased organ donation. Following ethics approval, recruitment was conducted utilising a qualitative purposive snowball strategy across Australia. A pilot study was conducted to test the study procedures prior to the main data collection, and 22 participants who had been involved in a deceased organ donation decision from nine families were interviewed. In five deaths family members had agreed to organ donation, and in four deaths the family declined. A theoretical framework based on the Precaution Adoption Process Model of decision-making was applied to propose trust, hope and deep hope underpin family organ donation decisions. xiii

14 Thematic analysis was conducted and three key themes comprising In the fog drowning, Harvesting humanity, and It s all up to Mum were revealed. The study found women, and in particular mothers, played a significant role in organ donation decision-making, and that the decision-making is bounded by family needs of trust, hope and deep hope across the continuum of time. It also found families who had their trust, hope and deep hope needs met expressed satisfaction about their decision-making experience and agreed to organ donation. Some families perceived that organ donation was a sacrifice that was too great to endure, even if the deceased had previously indicated intent to donate, and therefore declined donation. This study found that families ideas of a peaceful death and organ donation are not mutually exclusive. It concludes that when decision-makers trust and deep hope needs are met they are more willing to agree to donation. This study recommends that the idea of a right to a peaceful death should be aligned with deceased organ donation practices and normalised. xiv
