Abstract: Healthcare systems in New Zealand and the western world are grappling with changes with an aging population; increased use of technology resulting in shorter inpatient stays, increasing chronic illness rates and people with complex health needs. Supporting people through the health system and meeting their needs is an aim of all services. Trying to support seamless transition and manage complex care requirements has become important for community health services. In the district health board, where the author works, the role of Liaison Nurse/Complex Coordinator was established to support this. This role has become important in reviewing what the best model of care for Community Health Services is and how to describe the current practices in this context in an appropriate way. The first section of the report reviews the literature and current practice in relation to liaison nursing. This section explores how to make the role clear and identify its clinical and organisational effectiveness, drawing out the key elements and aspects for this role that will contribute to a model of care. The second section progresses onto the clinical work related to managing patients with chronic illness and complex needs. Utilising literature to inform current practice when supporting patients through health transitions to achieve seamless care and identifying key aspects required to manage this and adding these aspects to the model of care. Following this, a review of current care models available and in use in the health care systems is undertaken. There are some elements and aspects similar in these models and those explicated in the previous sections. Finally a model of care is developed bringing all the key aspects and elements together. This model describes the practice of Liaison/Complex Coordination role in community health service in New Zealand and identifies the need for care, provision of care, outcomes of care provided and impact for the service and organisation. The author suggests that this model is relevant for any liaison or complex coordination role and could be a basis for other models of care to expand upon the specific needs for their services.

Abstract: The process of describing her scope of practice led the author to become interested in just how she has advanced her practice and the journey that unfolded. The author was introduced to a number of models or frameworks and these frameworks have been critiqued within this dissertation.

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.

Abstract: Over the last century the nursing profession has drawn from numerous theories and disciplines to construct its own theoretical foundations. While this diversity and flexibility may be one of the nursing profession's strengths it may have contributed to nurses' difficulty in explaining the complexities of their every day clinical work. This is a particular challenge for the domain of mental health nursing. This dissertation discusses how nursing models that have credibility at a clinical level can contribute to informing and advancing nursing practice. Models can achieve this by assisting nurses to conceptualise and articulate what it is they do that makes a difference to patient outcomes. Through this process nurses can maintain a distinct professional identity and establish themselves as effective members of multidisciplinary health team. Specifically, the application and limitations of Godkin's (2001) proposed model of a 'healing presence' to the author's own practice in a one-to-one nurse-adolescent client relationship in the mental health nursing is examined. It is claimed that a 'healing presence' provides a meaningful way to understanding the author's own practice. The proposed model of a 'healing presence' embraces the diversity of her background, and allows the author to maintain a nursing identity by providing a nursing framework to critique her practice, furthering her understanding of what it is that 'expert' nurses do and how this impacts on patient outcomes. Also suggested is that a 'healing presence' can contribute to the author's own and other nurses advanced nursing practice by making nursing visible to the multidisciplinary health team and to articulate “what it is that I do 'when I am nursing'”. Through presenting this dissertation, the author wishes to inspire other nurses to examine and understand their own practice.

Abstract: This thesis describes the journey of a practicing independent nurse practitioner and naturopath through the stories of five clients. The thesis is presented as a narrative and begins with an account of the events in the practitioner's life that lead to the specific study of natural therapies and the development of a cohesive practice using holistic health practices from a nursing perspective. The text essentially describes the process of establishing a private practice combining two disciplines of nursing and naturopathy in New Zealand. The study reveals how a nurse and naturopath's practice is based on the premise that it is crucial to recognise that the personal life and professional life of the nurse inform and influence each other and are always part of the process of care in such a practice. Three healing modalities that are central to the practice are described in detail. The description is informed by theory and research from nursing, the social sciences and the natural sciences. The study reveals the practical value of postmodern nurse theorists, Jean Watson and Margaret Newman to this practice. This study also briefly discusses the concepts from quantum theory, evolutionary theory and psychoneuroirnmunology that are used in the practice.
