Abstract: Principles for understanding and evolving nurse practitioner practice, politics and policy are distilled from 40 years of experience in the United States and Australia. The issues in all countries are remarkably similar. The author suggests that some historical and conceptual grounding may assist the continuing development of this expanded role for nursing in New Zealand.

Abstract: The purpose of this research has been to trace the development of the nurse practitioner role in New Zealand. Using a discourse analytical approach informed by the work of Michel Foucault, the study foregrounds the discourses that have constructed the nurse practitioner role within the New Zealand social and political context. The author suggests that discourses of nursing and of medicine have established systems of disciplinary practices that produce nurses and physicians within defined role boundaries, not because of legislation, but because discourse has constructed certain rules. The nurse practitioner role transcends those boundaries and offers the possibility of a new and potentially more liberating identity for nurses and nursing. A plural approach of both textuality and discursivity was used to guide the analysis of texts chosen from published literature and from nine interviews conducted with individuals who have been influential in the unfolding of the nurse practitioner role. Both professionally and industrially and in academic and regulatory terms dating back to the Nurses Registration Act, 1901, the political discourses and disciplinary practices serving to position nurses in the health care sector and to represent nursing are examined. The play of these forces has created an interstice from which the nurse practitioner role in New Zealand could emerge. In combination with a new state regime of primary health care, the notion of an autonomous nursing profession in both practice and regulation has challenged medicine's traditional right to surveillance of nursing practice. Through a kind of regulated freedom, the availability of assessment, diagnostic and prescribing practices within a nursing discourse signals a radical shift in how nursing can be represented. The author concludes that the nurse practitioner polemic has revolutionised the nursing subject, and may in turn lead to a qualitatively different health service.

Abstract: This research paper reports on the findings of a literature review conducted to establish and analyse the international magnitude, context and effectiveness of nurse-led heart failure initiatives. The research revealed that the underlying philosophy in establishing nurse-led disease management programmes of care is that, by treating chronic heart failure as a continuum, it is possible to decrease exacerbations and improve patient outcomes. Regardless of the type of heart failure management programme, critical components of care include a collaborative supportive approach that educates and empowers the patient (including family/whanau) to recognise the early indicators of exacerbation, access expedient care, and to adhere to evidence based treatments. The author points to significant evidence to support the establishment of nurse-led heart failure programmes. The positive outcomes associated with this model of care delivery include decreased readmissions, reduction in mortality, and cost efficiencies. However, the organisational model of care, or programme components that are the most effective in optimising patient outcomes, need to be selected on the basis of local healthcare infrastructure, services and resources. The author suggests that New Zealand has a unique opportunity to encompass the recent emergence of the Nurse Practitioner role in facilitating, coordinating and monitoring of heart failure programmes across the continuum of care. The delivery of evidence-based, cost effective, heart failure programmes is a prerequisite to improving the delivery of optimal treatment and ensuring that heart failure patients have the opportunity to attain quality care outcomes.

Abstract: The introduction of nurse practitioner registration into New Zealand in 2001 was heralded as a move that would open up a wealth of opportunities for registered nurses to extend their practice into more independent roles and to provide a client-centred health service. It was also seen as a way to retain experienced registered nurses in the clinical practice area by providing a credible clinical career pathway. If nurse practitioner's are to meet these expectations, then, the author suggests, it is important to understand the processes that encourage or discourage nurses from advancing their practice. One of the early scopes of practice to be introduced was nurse practitioner with an endorsement in aged care scope of practice. Grounded theory was the method used to generate an explanation of how registered nurses working in aged care were preparing for the introduction of nurse practitioner roles. An analysis of early data highlighted codes around registered nurses in aged care extending and advancing their practice rather than preparing specifically for the nurse practitioner role. The research question for this study was: 'How are registered nurses in aged care advancing their nursing practice?' Semi-structured interviews were used to collect data from ten experienced registered nurses working in aged care clinical practice settings ranging from secondary hospital facilities, to community settings and residential care villages. Dimensional analysis of the data eventually generated three major conceptual categories: 'ownership of nursing', 'extending practice', and 'moving out of a comfort zone'. Of these, 'ownership of nursing' was identified as the core construct that linked the other categories together. The substantive theory that explains how registered nurses in aged care advance their clinical practice is 'developing autonomous ownership'. Nurses who develop autonomous ownership of nursing are more likely than other nurses to move out of a current comfort zone and advance their practice into more independent roles that suit their autonomous ownership of nursing. This study identified important contextual factors and conditions that support the development of an autonomous ownership of nursing and that subsequently facilitate advancing nursing practice. These include creating supportive environments, organisational commitment to advanced nursing practice roles, visible nursing leadership, congruence between organisational and nursing philosophies, interdisciplinary collaboration and participating in postgraduate education. The author suggests that the significance of this study is that it generated a theory about the processes that encourage or discourage nurses from preparing for, and progressing into, advanced nursing practice roles such as nurse practitioner.

Abstract: This thesis examines the forces influencing the development of contemporary advanced nursing practice in New Zealand. It begins with an historical approach to explore the various meanings of advanced nursing practice from the late 1800s through the first years of the 21st century. Seven historical understandings of the meaning of 'advanced' nursing practice emerge. The author's analysis of the broad scope of New Zealand nursing history, including a case study of the development and implementation of the nurse practitioner, draws on theoretical perspectives from sociology, political science, and nursing. She develops a “framework of critical factors for nursing to take into account when considering how to ensure the profession is able to deliver on its great potential to improve the health of New Zealand communities”. Examining the work of a range of nursing leaders, past and present, and drawing on the work of political scientist, John Kingdon, the author describes the work of several nurses as “policy entrepreneurship.”

Abstract: This dissertation reports on a scholarly journey to better understand the processes of clinical decision-making by nurses. It begins by identifying the various terms used to describe a clinical decision, its components and the contexts within which clinical decisions are made. Two philosophies of decision-making are summarised. Some insight into the history of the phenomenological and the rationalist theories of decision-making is offered. The author notes that it became evident that both of these theories are applicable to all nurses and their clinical decision making competencies. Four studies that were undertaken to analyse the decision-making methods of nurse practitioners are critiqued. Of the studies two are British, one is American and one is Australian. The author has summarised the combined findings that identified that the nurses were using a blend of decision-making processes that involved rational decision making as well as the use of intuition. The studies identified that sound clinical decision-making is determined by appropriate educational and clinical preparation and supported by a formal mentoring process and the use of critical reflective practice. In conclusion, the author reflects on her knowledge of decision making prior to embarking on the dissertation and states her intent to facilitate and support advanced decision-making by her colleagues. She goes on to say that uppermost is the need for an institutional and managerial environment that encourages advanced and independent decision-making by nurses.
