Abstract: This thesis concerns an investigation of the tripartite arrangements between the government, the nursing and the medical sectors in New Zealand over the period 1984 to 2001 with a particular focus on primary health care. The start point is the commencement of the health reforms instituted by the Fourth New Zealand Labour Government of 1984. The thesis falls within a framework of critical inquiry, specifically, the methodology of depth hermeneutics (Thompson, 1990), a development of critical theory. The effects of political and economic policies and the methodologies of neo-liberal market reform are examined together with the concept of collaboration as an ideological symbolic form, typical of enterprise culture. The limitations of economic models such as public choice theory, agency theory and managerialism are examined from the point of view of government strategies and their effects on the relationships between the nursing and medical professions. The influence of American health care policies and their partial introduction into primary health care in New Zealand is traversed in some detail, together with the experiences of health reform in several other countries. Post election 1999, the thesis considers the effect of change of political direction consequent upon the election of a Labour Coalition government and concludes that the removal of the neo-liberal ethic by Labour may terminate entrepreneurial opportunities in the nursing profession. The thesis considers the effects of a change to Third Way political direction on national health care policy and on the medical and nursing professions. The data is derived from various texts and transcripts of interviews with 12 health professionals and health commentators. The histories and current relationships between the nursing and medical professions are examined in relation to their claims to be scientific discourses and it is argued that the issue of lack of recognition as a scientific discourse is at the root of nursing's perceived inferiority to medicine. This is further expanded in a discussion at the end of the thesis where the structure of the two professions is compared and critiqued. A conclusion is drawn that a potential for action exists to remedy the deficient structure of nursing. The thesis argues that this is the major issue which maintains nursing in the primary sector in a perceived position of inferiority to medicine. The thesis also concludes that the role of government in this triangular relationship is one of manipulation to bring about necessary fundamental change in the delivery of health services at the lowest possible cost without materially strengthening the autonomy of the nursing or the medical professions.

Abstract: The purpose of this thesis has been to explore the discursive production of delirium in people over the age of 65 years. The philosophical approaches underpinning the study were derived from the field of critical gerontology, postmodernism and the utilisation of a Foucauldian understanding of discourse and power/knowledge. Data sources included published documents on delirium, interviews with people over the age of 65 years who had been delirious (as well as their clinical notes), family members, registered nurses and a doctor. Textual analysis revealed the presence of two contesting and contradictory discourses that impacted on being an older person who had delirium. These were identified as the discourse of delirium as a syndrome and a personal discourse of delirium. The discourse of delirium as a syndrome is underpinned by the biomedicalisation of the ageing process. This process utilises scientific methods as the foundation from which to understand, research and provide a health service to older people with delirium. Any personal perspectives on delirium are rendered unimportant and relegated to marginalised positions. Nursing through its vicarious relationship to medicine is interpellated into deploying the discourse of delirium as a syndrome and has largely ignored the personal dimensions associated with this phenomenon. Consequently, the older delirious 'body' is known and inscribed as unruly, problematic, physically unwell, cognitively impaired and at risk. Conversely, a personal discourse of delirium privileges the individual narratives of people who have been delirious and provides a different perspective of delirium. The deployment of a personal discourse of delirium offers another position that views this group of older people as bringing to the health care setting a rich tapestry of life experiences that are more than a cluster of signs and symptoms. It is these varied life experiences that need to be included as a legitimate source of knowledge about delirium. This thesis demonstrates how nursing needs to espouse a critical gerontological position when working with older people who have delirium. Critical gerontology provides nurses with the theoretical tools to challenge the status quo and uncover the multiple, varied, contradictory and complex representations of delirium in older people.

Abstract: Accountability has been described by nurses as an elusive concept or myth. The author suggests that this elusive concept or myth can partly be attributed to accountability becoming visible usually following a critical incident. The overall goal of this project is to provide nurses working within mental health with the incentive to raise their awareness and explore what their roles and responsibilities are within the accountability process in a more positive scenario. This research paper reports on an exploration of the key components of accountability within the New Zealand mental health environment. It describes significant influences that affect accountability. This is achieved by the means of a literature review, sharing of the author's experience of being involved in a national inquiry, and the adaptation of a who what and how framework, in conjunction with a diagram displaying accountability levels and lines for mental health nurses. The author points out that the domains of accountability for nurses will continue to evolve and expand but what remains important is that consumers have access to good quality mental health care.

Abstract: This study uncovers the experience of being ethical from the perspective of pre-registration nursing students. Using the qualitative methodology of phenomenology, specifically that outlined by van Manen, it seeks to show how students act ethically within everyday practice. Providing nursing care is an ethically charged undertaking and despite ethics taking an increasingly important place in nursing education, the author suggests that few studies show the contextual nature of ethical practice from the perspective of students. This study aims to partly redress this situation. In this study the author has interpreted the experiences of twelve pre-registration students. Using seventeen stories shared by the student participants, the author's personal understandings and literature, the meaning of being ethical has been illuminated. Three themes emerged from the interpretation. These include 'keeping things 'nice'', 'being true to yourself' and 'being present'. This thesis asserts that the overarching theme within these themes is that of 'being constrained and enabled'. Being constrained shows the experiences of students as they live through the tensions of being and doing as they strive to be ethical. Being enabled shows the experience of self-determination. Finally the study maintains that the shaping of ethical practice for undergraduate students may be enhanced when their reality is positioned and valued within educational processes.

Abstract: The aim of the study was to determine the practice of nurses employed in integrated care projects in New Zealand from late 1999 to early 2001. Integrated care was a major health reform strategy that emphasised primary health care as a means to improve service provision between the health sectors. An investigation of nurses' practice sought to determine the extent to which primary health care principles had been adopted in practice, as a comprehensive primary health care approach has been advocated globally in the management of chronic conditions; the leading cause of disability throughout the world and the most expensive problems faced by health care systems. The philosophical basis of the research was postpositivism. The study employed a quantitative non-experimental survey design because it allowed numeric descriptions of the characteristics of integrated care projects to be gained for the purpose of identifying nurses' practice. The unit of inquiry was the integrated care project, and 80 comprised the study population. Data were obtained on projects from expert informants (n=27) by telephone survey using a structured interview questionnaire developed by the researcher. Data obtained from interviews were statistically analysed in two stages. First, data were produced to comprehensively describe the characteristics of integrated care projects and nurses practice. The 'Public health interventions model' was used as a framework to analyses the interventions (activities) and levels of population-based practice of nurses. Following this, the social values embedded in nurses' practice were determined using 'Beattie's model of health promotion' as a framework for analysis. A strong association was found between nurses' practice in projects and strategies used in integrated care, such as information sharing, guideline development and promotion, and case management, and projects with an ethnic focus, low income focus, chronic condition focus, and well-health focus. Whilst nurses undertook interventions most frequently at the individual practice level they were also strongly associated with the small proportion of interventions that were undertaken at the community level. The majority of interventions by nurses reflected the health promotion value of health persuasion, indicating a paternalist and individual-oriented philosophy. Nurses were engaged in two interventions that indicated a collective-oriented philosophy – coalition building and community development, the latter reflecting health promotion values of negotiation, partnership and empowerment. The study demonstrated that nurses' practice in projects was predominantly centred on individual-focused population-based practice suggesting the need for a framework to assist nurses to transition their practice to include more activity at the community and systems levels. Without a reorientation of practice, nurses will remain limited in their ability to achieve health gains for populations. In response to this conclusion, and drawing on research results and reviewed literature, a new model, The 'Primary Health Care interventions model' was constructed. Recommendations include advocacy for the acceptance of the model by the health funder, professional nursing bodies, health organisations, educational institutions, nurses, communities, and individuals.
