Abstract: Psychiatric consultation liaison (PCL) nursing is an evolving specialist area of mental health nursing in the USA, UK, Australia and New Zealand. The aim of this dissertation is to explore models of PCL nursing practice in order to develop and discuss a PCL nursing model applicable to the New Zealand context. The role of the PCL nurse was of particular interest to the author as a new practitioner in this specialist area. While there have been PCL nurses in practice for over 50 years, the literature does not offer much clarity about models of PCL nursing. From a review of the literature, four themes were recurrent in the work of PCL nurses. These themes represent four functions which are vital to the role of the PCL nurse: partnership, expertise of the PCL nurse, therapeutic relationship and organisational consultation. The needs of the patient are the core of this model and the primary objective is to improve the quality of care of patients in the general hospital with co-existing physical and psychological problems. It is imperative that PCL nurses evaluate their practice and embark on research to investigate clinical outcomes, cost effectiveness and the impact of PCL nurse practice on patients and staff. This PCL nursing model provides a beginning for this process. It also clarifies and articulates the role of the PCL nurse which enables the service to be promoted to colleagues. This PCL nursing model represents a critique of the author's understanding of the role of the PCL nurse. As expertise develops, the model will continue to be tested and refined.

Abstract: Rural nursing in the remote context of South Westland is shaped by factors common to rural nursing practice world-wide including geographical and professional isolation, living and working in a small community, providing health care to rural people and the broad, generalist and advanced scope of nursing practice. Tourism is a major industry in the townships in the proximity of the two accessible glaciers in South Westland. The practice of the nurses in these areas is significantly affected by tourists seeking health care and by providing a health service for the large number of migrant seasonal workers who service the tourist industry. Tourists seek health care from the nurses across the full spectrum of health problems and their expectations of the health care required may exceed the service that can be provided. The nurses are challenged to advance their practice to find the personal and professional resources to provide a safe service. This includes the challenge of cultural safety and personal safety. The tourist industry brings significant numbers of young people as seasonal/temporary workers to the glacier areas. This imposes a youth culture onto the existing rural culture. Nursing practice has expanded to include the specialist practice of youth health care that includes the problems of alcohol and drug misuse, sexual and reproductive health, and youth mental health. This work is drawn from the experience of the nurses working in the glacier communities. The impact of the tourism industry on their rural nursing practice includes the increasing volume of work that challenges the viability of the service, the advanced scope of practice required to meet the health needs of tourists and the seasonal tourist industry workers, and challenges to personal and professional safety.

Abstract: Effective nursing prioritisation of the patient need for care is integral to daily nursing practice but there is no formal acknowledgement or study of this concept. Utilising the retroductive research strategy of critical realism, this thesis explores the nursing literature for the tacit knowledge of the discipline about nursing prioritisation and proposes a 'fit' for nursing prioritisation of the patient need for care within the bigger picture of nurse clinical decision-making. The tacit knowledge discerned within the literature indicates that nurses use discretionary judgment and ongoing assessment to determine the relative importance of the many aspects of individual patient situations as they unfold. Such nursing prioritisation takes place concurrently between the competing or even conflicting needs of the several individual patient presentations within the nurse's caseload. Varied frames of reference within different practice settings create specific imperatives on this dynamic and non-sequential process. Starting with an initial set of studies in the 1960s, study of clinical decision-making in nursing has created a significant body of knowledge encompassing a range of approaches. Nursing prioritisation of the patient need for care is most readily discerned in the interpretive perspective and in the plain language descriptions of nurse decision-making. Within the selected literature it is apparent that nursing prioritisation of the patient need for care is an advanced skill of nursing that is developed in practice and honed through experiential learning.

Abstract: The last twenty years, particularly the early 1990s, ushered in major mental health sector reforms inclusive of deinstitutionalisation policies and subsequent development of community services. Concurrent changes to student nurses' education left registered nurses as the workforce mainstay on inpatient units. However, the author suggests, an emerging global shortage of nurses and implementation of the Employment Contracts Act (1991) negatively impacted on recruitment and retention of registered nurses. Inpatient nurses either left nursing or moved to community positions for better money and increased job status. The author suggests that, as a consequence, the 'critical mass' of experienced and skilled nurses who traditionally provided nursing leadership disappeared resulting in compromised standards of care for patients. As the manager of an inpatient unit, the author proposed the establishment of advanced nursing practice roles as one initiative to provide nursing leadership in order to attract and retain nurses. This study explored five inpatient nurses' perceptions of advanced practice and whether these roles could assist to provide leadership and improve standards of care. The research was a qualitative exploratory descriptive study using a focus group interview as the data collection method. A thematic analysis of the group discussion transcription revealed three key themes: 1) the 'makeup' of advanced nursing practice, 2) moving forwards: establishing roles, 3) moving sideways: barriers to role development. The themes are critically discussed in relation to selected literature. The thesis includes recommendations that could be used by nurses responsible for planning and implementing advanced practice roles on inpatient units.

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.
