Abstract: Respiratory nursing has, as a core clinical concern, the alleviation of distress and suffering associated with respiratory disease. This research describes the ways in which experienced New Zealand respiratory nurses understand, assess, manage and support patients suffering from chronic breathlessness. It reviews the professional context in which these nurses practice, and examines the experiences and beliefs that have lead them to, and maintain them in, this area of practice. This study has been stimulated by the realisation that the skills, understandings and practice wisdom exhibited by experienced Respiratory Nurses is poorly described in the published research literature. This qualitative, grounded theory research is based upon data gathered from in-depth interviews with six experienced New Zealand respiratory nurses. A constructivist research position is adopted. Analysis of these interviews revealed distinct phases of developing respiratory nurse practice including preparing and entering respiratory nursing practice, comprehension of the phenomena of chronic breathlessness and the effect upon the patient and the seeking of possibilities which may alleviate and modify the debilitating effects of chronic breathlessness. Consistent values and beliefs are identified, which are captured in the concepts of professional caring and the movement towards developing expertise in practice. The unifying concept of journeying is employed to draw together these conceptual elements and develop a substantive model describing the work of experienced respiratory nurses with patients with chronic breathlessness. Implications for practice and the health system, and suggestions for further research, are discussed.

Abstract: This study explored the experiences of hospitalised patients in methicillin resistant Staphylococcus aureus (MRSA) isolation in New Zealand and the meaning that those patients made of those experiences. The research question of this study was 'What is the lived experience of patients in MRSA isolation?' An interpretive phenomenological approach was undertaken for this research, informed by the philosophical hermeneutic tenets of Heidegger (1927/1962). Audio-taped, semi-structured interviews were used to collect data from a purposive sample of ten adults who were in MRSA isolation in various wards in a large acute care hospital in the central North Island. Three salient themes emerged from the data. The first, 'being MRSA positive', summarises the meaning of having an identity of being MRSA positive. The second theme, 'being with others', is concerned with the effect that being in isolation for MRSA has on interpersonal relations. 'Living within four walls' is the third theme and reveals the significance that the physical environment of the MRSA isolation room has on the experience of MRSA isolation. Within the discussion of these themes, excerpts from the interviews are provided to illuminate the meanings and interpretations made. Recommendations are made for nursing practice and education.

Abstract: This thesis contains a collection of stories gifted by four New Zealand Retrieval Team nurses who are experienced in the transport of patients. These nurses are commonly called flight nurses and they assist in the transport of patients via helicopter, fixed-wing aeroplane, large commercial aeroplanes and ambulances. While their practice is not exclusively in the helicopter there is an emphasis on this mode of transport in this thesis. Flight nursing is a scope of nursing practice where the use, and visibility, of nurses' stories is rare. The specific context of this research is positioned in one tertiary intensive care unit in New Zealand but it is anticipated that the stories from four flight nurses and the author's subsequent thoughts on them will resonate with flight nurses in other regions. The stories were collected using a storytelling methodology that has been informed by qualitative and feminist perspectives. The stories were either gathered and shaped using interview and transcription techniques with the storyteller and the researcher, or written by the storyteller. The thesis has been written as a narrative and chronicles the journey to the point of receiving the stories and the lines of inquiry in which they subsequently directed the author. The stories are central to this research and appear in their entirety. The reader is encouraged to create their own meaning from the stories. The stories themselves have several common threads, which are planning, communication, teamwork and the unexpected. The threads underpinning the stories are not unique to flight nursing practice and have been discussed in other scopes of practice. One area the author has chosen to explore in more depth is the impacts of technology, privacy, narrative pedagogy and disenfranchisement on the visibility of flight nurses' stories. The other area she has chosen for discussion is advanced and specialty nursing practice as it relates to flight nurses. As a result of this discussion she proposes her own view for advanced and specialty practice in flight nursing.

Abstract: The author reconsiders the meaning of expert, specialist and advanced practice. She proposes that they are distinctive and complementary aspects of every nursing role and suggests a set of attributes for each. Expertise is discussed in terms of the quality of performance, speciality in relation to particularity of performance, and advanced practice with regard to the level of performance.

Abstract: This aim of this thesis was to explore and describe registered nurses' experiences of undertaking the statutory role of Responsible Clinician under the Mental Health (Compulsory Assessment and Treatment) Act 1992. The role of Responsible Clinician has been available to nurses since 1992 yet to date there has been little research into nurses' experiences of undertaking this role. An exploratory descriptive approach was therefore used in this study. A convenience sample of four nurses who had been undertaking the role of Responsible Clinician was recruited. Their experiences were elicited through in-depth interviews. Analysis of the interview material revealed the themes of legitimacy, relationships, expanding practice, responsibility and accountability, approaches to care, nurses' responsiveness to the role and support of the role. The author points to this research being important to nurses who are working in the psychiatric mental health area so that they can understand the role more fully. In this way, more nurses may choose to undertake the role of Responsible Clinician.

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: This research is an exploration and interpretation of the lived experiences of family members since they lost a close family member to suicidal death. The findings have implications for nurses and counsellors working in the area of suicide bereavement. Heidegger's hermeneutic phenomenology was utilised and informed by van Manen's and Benner's work. Data from in-depth interviews with six participants, the researcher's journal entries and published literature were analysed. Findings gave rise to a grief model where suicide survivors moved through four modes of being-in-the-world characterized by 13 lifeworlds or themes. Surviving suicide was a transformative process that in time enabled survivors to discover new ways of understanding and relating to the world.
