Abstract: Using thematic analysis, this study explored the phenomenon of effective education for critical care nursing practice by asking: What does effective education for critical care nursing practice mean to nurses currently practising in the specialty? Eighty eight critical care nurses from the South Island provided written descriptions of what effective education for critical care nursing practice meant to them. Descriptive statements were analysed to reveal constituents, themes and essences of meaning. Four core themes of personal quality, practice quality, the learning process and learning needs emerged. Appropriateness or relevance for individual learning needs is further identified as an essential theme within the meaning of effective education for critical care nursing practice. Shared experiences of the phenomenon are made explicit and discussed with reference to education and practice development in the specialty. The study results lend support to education that focuses on individual learning needs, and identifies work based learning as a potential strategy for learning and practice development in critical care nursing.

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 thesis describes the maternity system in Wellington between 1950 and 1970 particularly from the perspectives of consumers and midwives. Four women consumers who experienced maternity in Wellington and two midwives who worked in Wellington's maternity hospitals during this period provided their oral testimonies as the main primary sources for this study. The author's experience of being a student nurse and a consumer in Wellington and other primary and secondary sources are used to substantiate, explore and explain the topic. The study traces the socio-political changes in New Zealand maternity from 1900 to 1970 creating a backdrop against which Wellington's maternity system, including the women, the hospitals, the workforce, maternity practices and the childbearing process are illuminated using the insights of women and midwives who experienced them. The oral testimonies of the six participants described positive and negative aspects of their maternity experiences, but the three strong themes that arose from their accounts included 'being alone', 'lack of autonomy' and 'uncaring attitudes'.

Abstract: This study, which is undertaken in the Southland area, explores the effect of the increasing specialisation of nursing services in what is a rural/urban environment. It is indicated in the literature that systemic changes in health, such as the health reforms, and the increase in the use of technology have meant that nurses are required to function in disease oriented roles rather than according to their more traditional generalist roots. A significant event, which also affected nursing scope of practice, was the transfer of nurse education to the tertiary education institutions environment from the hospitals in the mid 1970s. The traditional nursing hierarchy and its nurse leadership role disappeared and the adoption of specialist nurse titles increased, and identified with a disease or disorder, for example 'diabetes' nurse. The increase in specialist categories for patients contributed to the nurse shortage by reducing the available numbers of nurses in the generalist nursing pool. The nurses in this rural/urban environment require generalist nurse skills to deliver their nursing services because of the geographical vastness of the area being a barrier to specialist nurses. Workforce planning for nurses in the rural/urban then must focus on how to reshape the nursing scope of practice to utilise the existing resources. This study explores how key areas of health services could be enhanced by reclaiming the nurse role in its holistic approach, in mental health, public health, geriatric services and psychiatric services.

Abstract: This study explores the experience of being an orthopaedic nurse. As an orthopaedic nurse the author had concerns that the validity of orthopaedic nursing as a unique scope of practice was being questioned. In this thesis, the case for orthopaedic nursing is argued, by showing it as a specialty in its own right. A qualitative approach informed by the author's interpretation of philosophical hermeneutics as articulated by Heidegger (1927/1962) and Gadamer (1976; 1989) was undertaken. Phenomenology seeks to uncover 'taken-for granted' meanings in everyday experience and hermeneutic research recognises that the historical and cultural horizons of participants and researcher influence the interpretation. Eight nurses working in various orthopaedic settings were interviewed. Data was analysed using the interpretive thematic approach described by van Manen (1990). The nurses' stories from practice yielded two essential themes, 'being part', and 'gaining and maintaining integrity'. The author concludes that these themes interrelate and together reveal meanings and insights about being an orthopaedic nurse. 'Being part', shows the essential nature of relationships between orthopaedic nurses and others. 'Gaining and maintaining integrity' describes the embodied nature of the phenomenon. The overall thematic finding 'seeing the world through orthopaedic eyes' reveals the nature of orthopaedic nursing as a unique scope of practice.

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 research study examined the role of the public health nurse. Utilising community needs analysis method, 17 key informants and two focus groups were asked questions to determine perceptions of the public health nurse. Findings indicated that participants lacked knowledge regarding the role. Additional findings intimated that participants had difficulty in accessing public health nurse services and that 'knowing the system' was beneficial to receiving needed care. One of the major conclusions of this study was that many facets of care managed by public health nurses were invisible to the communities in which they work. Conclusions suggest that public health nurses need to enhance their service by improving accessibility to services and promoting their service in a more visible manner.

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.
