Abstract: This thesis reports a mixed methods study, longitudinal in nature, of consenting Age Related Residential Care (ARRC) hospitals in the upper half of the North Island, which was conducted to examine several factors, including AARC hospital efficiency at producing adverse event free days for residents. An interpretativist approach examined what best practice strategies were implemented by the ARRC hospitals that were identified to be most successful at producing adverse event free days for the residents.

Abstract: This study explored the potential for extending the contribution nurses make in managing patients with chronic kidney disease as they progress to end stage kidney failure. In the context of a shortage of nephrologists and an escalating patient population suffering from kidney disease, the potential to include advanced nephrology nursing in early disease management was postulated. The literature was reviewed with regard to initiatives to reduce the progression of kidney failure and the prevention of associated complications. Local and international literature on advanced nursing practice and the nurse practitioner role was examined in relation to the management of chronic kidney disease. The introduction of the nurse practitioner in New Zealand could provide an ideal framework for independent nephrology nursing. Well-established nursing practice in dialysis, transplantation and pre-dialysis provide distinct scopes of practice in these areas for independent nursing in the future. It seems likely that these sub-specialties in nephrology nursing will be the first to experience the value of the nurse practitioner. The creation of early interventionalist nurse practitioners in nephrology health care would allow nurses to step outside these well-established sub-specialties, and provide new resources to help manage chronic kidney disease. A model of care was proposed that outlines how a nephrology nurse practitioner could work collaboratively with community health providers and the local nephrology health care team to manage the early stages of kidney disease.

Abstract: This descriptive case study was undertaken to provide an account of chemotherapy practice in a nurse-led clinic located within a rural New Zealand area. The researcher, an oncology nurse specialist, worked alongside colleagues for thirteen months to enable practice development. This clinic developed out of a need to have services closer to rural patients in order to address issues of equity, access, care integration and the fiscal and social constraints associated with the cancer burden of care. Capturing the range of data applicable to this case; the ability to conceptualise it as a service within its context was possible using case study research methods. Four nurses involved in the chemotherapy clinic were participants in this study. The findings of this study reveal that what could be perceived as barriers to outcomes and practice can in essence be turned into opportunities to develop new ways of caring for the patient and supporting nursing practice. These nurses view their practice as safe within the clinic despite resource constraints. They work in many ways to support each other and to cushion the patient from the impact of situational and contextual influences. Nursing practice was shown to evolve as a direct result of internal and external influences which were the impetus for nurses taking responsibility for their own competency. This study also explored what it meant to be an experienced nurse but novice in a speciality practice. It challenges previously held assumptions that, to deliver chemotherapy successfully, a nurse needs to be operating from a previously held body of oncology nursing knowledge. Many challenges are faced on a day to day basis in a rural practice environment to just maintain consistent care and promote good patient outcomes. The nurses are well aware of their role in contributing to patients' quality of life and the roles they take to meet the growing needs of the patient as a consumer. This study delves into the multifarious nature of this nurse-led clinic and discusses the processes and relationships that are forged to deliver care.

Abstract: This study originates from the author's practice experience working for the New Zealand Fire Service back in the late 1980's and early 1990's as an Occupational Health Nurse where she piloted a Critical Incident Stress Peer Support programme in the No.4 Region. The author identified work-related stress and related it to Critical Incident Stress (CIS) from firefighters exposure to critical incidents. This study explores four firefighters experience of Critical Incident Stress Debriefing (CISD) within a Region of the New Zealand Fire Service. It explores the application of CISD as one component of Critical Incident Stress Management (CISM), and the Nurse Researcher's philosophy of Clinical Nurse practice in relation to the application of CISD. The knowledge gained from the analysis of the data has the potential to influence professionals understanding of their experience and affect future practice and that of others working in the field of CISM. Much of the literature that supported CISD appeared to offer a rather superficial understanding of the firefighters experience in relation to CISD. A narrative approache was chosed as the methodology, utilising four individual case studies as a method of social inquiry in order to explore the experience of CISD. The narratives were able to creatively capture the complexity and the dynamic practice of CISD. An overall pattern of the formalised process was uncovered through the participants' narratives. Eight dominant themes were highlighted from the narratives which included safe environment; ventilating the stress reaction; similar feelings; getting the whole picture; peer support; bonding and resolution. While these themes were common to all the participants, each participant had a particular theme/s which was unique to their experience.

Abstract: This thesis reports on a retrospective observational study that examined the complication rate of peripherally inserted central catheters (PICCs) within a regional cancer centre. PICCs are increasingly used for delivery of chemotherapy and other intravenous therapies in oncology patients. A literature review revealed that almost all published research on PICC complications reported on silicone (Groshong(TM)) catheter use, rather than the polyurethane (Arrow(TM)) PICCs used at Christchurch Hospital. Also, much literature referred to PICCs being inserted by non-nurses, whereas the Christchurch service uses specially-trained nurses to insert them. The purpose of the study was to identify the nature, incidence and rates of polyurethane (Arrow(TM)) PICC complications in an adult oncology cohort. Ethics Committee approval was gained to retrospectively follow all PICCs inserted in adult oncology patients at Christchurch Hospital over a 13-month period from 1st March 2006 until 31st March 2007. Data collected were analysed utilising the statistical computer package SPSS. One hundred and sixty-four PICCs were inserted into 156 individual oncology patients over this period. The median dwell time was 68 days for a total of 14,276 catheter-days. Complications occurred in 25 (15%) out of 164 PICC lines, in 22 (15%) of the 156 patients for an overall complication rate of 1.75 per 1000 catheter-days. However, only 16 of the 25 PICCs with complications required early removal (9.75% of the cohort) for a favourably low serious complication rate of 1.12 per 1000 catheter-days. The three commonest complications were infection at 4.3% (7/164) or 0.49 infection complications/1000 PICC-days, PICC migration at 3% (5/164) or 0.35/1000 catheter days, and thrombosis at 2.4% (4/164) or 0.28/1000 catheter days. The median time to complication was 41 days. Those with complications were more likely to have a gastro-intestinal or an ovarian cancer diagnosis, and less likely to have colorectal cancer. These findings provide support for the safe and effective use of polyurethane (Arrow(TM)) PICCs for venous access within the adult oncology context. Furthermore, it suggests that cost effective nurse-led (Arrow(TM)) PICC insertions can contribute to a low complication rate.

Abstract: Traditionally the use of advanced physical assessment skills when assessing a patient or client has been the domain of the medical profession. The last few decades has seen many changes in health provision that have influenced nursing practice, as a result of the social and economic trends impacting on New Zealand society. A notable change in nursing practice has been an increased emphasis on the use of advanced physical assessment skills by registered nurses, as an expected part of the registered nurse's health assessment. Nurses in the United States, and more recently Canada and Australia, readily include these skills as an expansion of their health assessment into their nursing practice. The purpose of this research is to investigate whether New Zealand registered nurses have done the same. The factors that influence the registered nurses' use of these skills are also explored. This descriptive design was chosen in order to focus on exploring and describing this phenomenon in a holistic fashion. Data collection involved one hour semi- structured interviews with seven participants who all completed the same postgraduate advanced health assessment educational course. Three themes were identified as influencing the use of advanced physical assessment skills; the registered nurse's work environment, the registered nurse's attributes and the registered nurse's original nursing education. The findings from this research have implications for nurses in practice and nurse educators, in both undergraduate and postgraduate education.

Abstract: The development and role of the clinical nurse specialist in New Zealand is the focus of this dissertation. It is an area that has not clearly been documented previously and the author hoped that by articulating this role to nurses, educators, and administrators that the role of the clinical nurse specialist will be more clearly defined and perhaps recognised for the contribution it provides to health care in New Zealand. At present, it is difficult to justify the clinical nurse specialist position in New Zealand, when individuals have been left to define and develop their own positions. This has led to widely differing practice modes and role confusion, and therefore a varying degree of success in achieving improved nursing practice. Without title protection and some form of accreditation process to ensure standard of practice throughout the country it is not possible for post-holders to move from position to position throughout the country. The role and definition of the clinical nurse specialist must be clarified in order to reduce confusion. Restriction of the title to those who meet the defining characteristics will strengthen the role, improve collaboration with other members of the team as well as making it easier for the public to understand the role.
