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: Mothers, whose children had undergone a liver transplant more than one year ago at time of interview and whose children were outpatients of Starship Children's Hospital, were invited to participate in this research. A Heideggerian hermeneutic phenomenological approach, informed by the work of van Manen (1990) was used. Three mothers of children who had received a liver transplant were interviewed to reveal the meanings of the phenomenon – what is the meaning of lived experience of mothers in caring for their child who has undergone and recovered following liver transplantation? Little previous study regarding mothers' lived experience of caring for their child, who had recovered from a liver transplant, was found in the literature. The emerging themes were punctuated with stress being a consistent feature. Utilising Ruddick's (1983) concepts of maternal thinking, the emerging themes were merged within the three interests governing maternal practice; preservation, growth and acceptability. The absolute capacity for attentive love draws the experience together. An essential theme identified out of the analysis was the concept of survival relating to the unique features of liver transplantation and the consequences of liver rejection and failure. The findings contribute to the understanding of the phenomenon, emphasising the need for good support systems for families of children who have undergone transplantation; assistance in the establishment of maternal coping strategies and regular feedback on the children's progress acknowledging the role and care provided by mothers.

Abstract: This study explores the phenomenon of dilemma in paediatric practice. Using a hermeneutic phenomenological method informed by the writings of Heidegger [1889-1976] and Gadamer [1900-2002] this study provides an understanding of the meaning of 'being in dilemma' from the perspective of predominantly paediatric health care professionals but also families in New Zealand. Study participants include four families who had a child requiring health care and fifteen health care practitioners from the disciplines of medicine, nursing, physiotherapy, play specialist and occupational therapy who work with families and children requiring health care. Participants' narratives of their experiences of 'being in dilemma' were captured via audio taped interviewing. These stories uncover the everyday realities facing health professionals and families and provide an ontological understanding for the notion of dilemma. The findings of this study suggest that experience of dilemma for health professionals reveals a world that is uncertain and questionable where they are thrown into having to make uncomfortable choices and must live with the painful consequences of their actions. The consequences of being in such dilemma are having to find ways of living with the angst, or risk becoming too sensitive or desensitizing. For families the experience of dilemma reveals a similar phenomenon most evident in circumstances where they feel totalized by the impact of heath care encounters. This study has uncovered that the perspectives that health professionals and families bring to the experience of dilemma reveal different concerns and commitments and may be hidden from each other. This thesis proposes that health professionals and families need support in living with their own personal encounters of enduring experiences of dilemma.

Abstract: This study explored what some New Zealand families believe constitutes the successful management of unsupervised childcare. It was designed to increase social understanding and practitioner knowledge of the issue by exploring families' beliefs, practices and perspectives. The researcher was concerned with the professional role nurses may play with this group of children. A qualitative descriptive approach was used to obtain a straight description of successful unsupervised childcare, using the everyday language of the participating families. Data was collected in semi structured interviews with five family groups, and subjected to content and thematic analysis. Findings suggest unsupervised childcare is both choice and solution, though parents are fearful of the legal and social consequences of using it. Context of the care is important, with the child's preference, community context and availability of adults through distal supervision critical components of its success. Trust between parent and child, the use of rules and boundaries to regulate child behaviour, the teaching of skills and strategies to build child competency, and parental support of children while unsupervised are identified by parents as factors linked to success. Parents identify increasing child independence and self responsibility as positive outcomes from the successful use of unsupervised childcare. This study has helped to identify positive factors resulting in good outcomes from which successful interventions could be developed, provides information that will be of particular interest to practitioners and policy makers, and provides a platform to launch larger studies into the issue of unsupervised children.

Abstract: ABSTRACT
BACKGROUND: Emergency nursing is a specialty concerned with the care of people of all ages, with either perceived or actual unwellness presenting to the emergency department(ED) for assessment, resuscitation, investigation, treatment and review of their illness or injury. Emergency nurses apply specialty knowledge and expertise in the provision, delivery and evaluation of emergency nursing care. Over recent decades social, political and professional changes have affected nursing care delivery and nursing education. In particular the 21st century has witnessed the development of state funded postgraduate nursing education programmes, developing nurses specialty or advanced nursing knowledge, quality patient/client care and nursing practice within the tertiary education system.
AIM: The aim of this study is to investigate emergency nurses? perceptions of the impact of postgraduate education on their practice in New Zealand (NZ).
METHODS: This study utilises critical social theory as the overarching framework, informed by the writing of Jürgen Habermas (b.1929- ). It is the three phases of
Habermas?s practical intent of critical social theory; namely enlightenment, empowerment and emancipation, that this study is concerned with. This descriptive research study employs both quantitative and qualitative methods and is therefore known as mixed-methods research. Data collection took place over 12 weeks, from August to November 2006, using a survey questionnaire obtained with permission from Ms Dianne Pelletier, Sydney, Australia. The sample included 105 emergency nurses from District Health Board (DHB) emergency departments in NZ, 10 respondents from this sample self-selected to be interviewed by telephone. Ethical approval for this study was obtained from the University of Otago Ethics Committee for research involving human participants. Data was analysed using the Statistical Package for Social Sciences (SPSS).
RESULTS: Two main themes arose from the thematic analysis; these being positive and negative, these themes were further divided into 10 sub-themes. The results indicate that postgraduate study (PGS) has increased nurses? perception of their knowledge; leadership and understanding on the quality of patient care delivered, increased their academic and research skills and increased their confidence/self-esteem and recognition by their colleagues and team. Therefore the majority of respondents perceive postgraduate education has been an instrument of liberation and a process of empowerment and emancipation. A smaller percentage of respondents perceived that PGS had no effect on various aspects of patient care and another significantly smaller percentage of respondents reported negative results from PGS. This research identified similarities between this study and that of Pelletier and colleagues? (2003; , 2005; , 1998a; , 1998b) Australian study.
CONCLUSION: This study adds to the existing literature on postgraduate studies undertaken by nurses. No known study has previously investigated solely emergency nurses?perceptions of the effects of PGS, either nationally or internationally. The results of this study offer enlightening information regarding emergency nurses? perceptions of their PGS within NZ and offers a platform from which other studies may be undertaken. It also has the potential to inform nurses contemplating PGS and educators facilitating these programmes,as well as provide implications for policy development by the Nursing Council of NZ, NZ Universities, DHBs and the Ministry of Health.

Abstract: Professional development is an ongoing requirement of nurses as a result of the Health Practitioners Competence Assurance Act. The Act?s principal purpose is to protect the health and safety of the public by ensuring health practitioners are fit and competent to practise. This survey was designed to explore the avenues nurses have taken, and would prefer to take, for their professional development. The questionnaire was sent to a random sample of the New Zealand Nurses Organisation's registered and enrolled nurse members. Nurses overwhelmingly favoured professional development in the workplace. More than half the respondents reported a conflict with other time commitments, while a number of respondents wrote of their desire for work-life balance. The cost of fees, ability to take time off work, and time and travelling distance were all hurdles to professional development. Nurses cited information technology, conflict resolution, managing challenging behaviour, and dealing with rostered & rotating shifts as aspects of their current work for which their nursing education (pre and post) had not adequately prepared them. Nurses also indicated that their pre-registration education in health systems and political processes was inadequate for their current work. As nurses aged, their interest in professional development increased, though many still preferred workplace options. The authors conclude that, in order for professional development opportunities to be accessible and relevant, resources and time must be made available. This is vital to achieve ongoing education of nurses and improved patient outcomes. Management support, combined with effective assessment of learning needs guiding professional development opportunities, are fundamental to ensuring nurse competence.
