Abstract: Investigates the effects of participation in the Intensive Care Unit Randomised Trial Comparing Two Approaches to Oxygen therapy (ICU-ROX) randomised controlled trial, on attitudes and practices in relation to ICU oxygen therapy. Distributes a practitioner attitudes survey to 112 specialist doctors and 153 ICU nurses. Performs both inception and retrospective cohort studies using the Australian and NZ ICU adult patient database before, and post-publication of the ICU-ROX trial results.

Abstract: Examines the experiences of the patient, their family and healthcare professionals during the trajectory of a prolonged critical illness in an Intensive Care Unit (ICU). Conducts a qualitative, instrumental, multi-case study informed by the Chronic Illness Trajectory Framework. Analyses data from six linked cases (patient, family and clinicians) in four ICUs over a two-year period. Argues that identifying the sub-phases of a prolonged critical illness trajectory allows targeted interventions for each sub-phase.

Abstract: This research examines how nurses negotiate the context of the Intensive Care Unit (ICU) while working with families. The action research described in this thesis developed through a series of meetings and conversations where the conversations supported the reflexive intent of the research. In commissioning the research, the design of the meetings and conversations were as a series of overlapping actions. Data collection and data analysis occurred in the action research by meetings, reflective conversations, ad libitum observations, and in a research journal. Conceptual maps explain the progress and findings of the research in this thesis while categories distilled from the conversations also support the findings in the research. The Family Action Research Group that was established within this project proposed a Family Assessment Form for the family to provide an assessment of themselves and the patient. Implementing this assessment tool demonstrated that clear information was needed for the family in the ICU. Findings in this research focus on developing action research and family care in ICU. Findings also focused on the role of the researcher being of and not being of the context where action research is undertaken. Recommendations include staff examining relationships for potential asymmetries and seeking ways to address these to support families and staff. Suggested strategies for developing action research in a clinical context include detailed planning, clear focusing, transparency of data, and working to explain change initiatives through the research are also included.

Abstract: The author's art project “Posthuman Pathology” is a postmodern examination of the resolutely modernist culture of critical care medicine. She uses conceptual art practices in conjunction with the techniques of anti-aesthetics in order to dismantle, open out and critique ideas which are foundational to the culture of critical care.

Abstract: This study provides insight into the experience of being an ICU nurse and relative of a critically ill patient. Analysis of data from interviews of four ICU nurses who had experienced having a family member admitted to ICU brought up several themes. These included: a nurses' nightmare, knowing and not knowing, feeling torn, and gaining deeper insight and new meaning. Recommendations for organisational support for ICU nurse/relatives, and education for staff are made, based on the findings.
