Abstract: This qualitative thesis uses discourse analysis to examine parental resistance towards medical treatment of critically ill children. It is an investigation of the 'mobile and transitory' discourses at play in instances of resistance between parents, physicians and nurses within health care institutions, and an examination of the consequences of resistance through providing alternative ways of perceiving and therefore understanding these disagreements. The philosophical perspectives, methodology and methods used in this thesis are underpinned by selected ideas taken from the works of Michel Foucault and Pierre Bourdieu and supported by relevant literature in the fields of media, law, children, parenting, caring, serious childhood illness, medicine and nursing. It is argued that from an examination of interview based texts, parental resistance is an omnipresent but transitory occurrence that affects many of the interactions between the parents of seriously ill children and clinical staff. It is maintained that within these interactions, the seeds of this resistance are sown in both critical decision making situations and in everyday occurrences between doctors, nurses and parents within healthcare institutions. Contributing factors to parental resistance include the use of power games by staff, the language of medicine, forms of symbolic violence, the presence or absence of trust between parents and medical staff, the effects of medical habitus, and challenges to the parental role and identity. Overall, it is proposed in this thesis that parents who resist treatment for their seriously ill child are not exceptions to the normative patient-physician relationship.

Abstract: This study explored the perspectives of Pacific nurses on what it is like for them to work in a Pacific community mental health (PCMH) service within a district health board. Five Pacific Island nurses who worked in the three Pacific community mental health services based in the Auckland region participated in the project. The study employed narrative inquiry to gather data through focused storytelling method. The results of the study have indicated that PCMH nursing is a unique nursing field as well as highlighting significant practice issues for nurses. Complex service infrastructure and language have been found to be the major contributing practice constraints. The findings suggest the need for district health board authorities, Pacific mental health service management, professional nursing education and development programs to consider addressing these practice issues to prevent further increase in the problem of PCMH nurses shortage and enhance recruitment and retention of these nurses.

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: Critical Comparative Nursing Assessment (CCNA) is a theory about how the competence of completing Bachelor of Nursing students in New Zealand is determined. Semi-structured, audio-taped interviews and field notes were used to collect data from twenty-seven nurses with experience in undertaking competency assessment. A Glaserian grounded theory approach was used to guide the data collection and analysis. This utilised the processes of constant comparative analysis, theoretical sampling and saturation to generate a middle range substantive grounded theory. This is presented as a model consisting of four emergent categories that explain how nurses formulate professional judgements about competence. These are a) gathering, which describes the processes used to collect evidence of practice to inform decisions; b) weighing up, which explains how evidence is analysed using the processes of benchmarking and comparative analysis; c) judging brings into focus the tensions inherent in making professional judgements about competence and how nurses formulated these, and d) moderating, which describes the processes nurses use to validate decisions and ensure that professional responsibilities and public safety are upheld. The basic social psychological process of comparing integrates these categories to explain how nurses resolve the tensions associated with making decisions about competence. This research presents a new way of viewing and understanding how nurses assess competence. It identifies where the challengers and tensions related to the assessment of competence lie and suggests strategies that if implemented, the author suggests could further enhance the validity and reliability of assessment outcomes.

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 study investigated issues surrounding the high numbers of preventable admissions of young children with acute illnesses, particularly amongst Maori and Pacific children. It focuses on what happens once these children are discharged. Its aims were to find out what the expressed needs of parents were, as they cared for their child, once home. Whilst there has been a small amount of international research undertaken in this area, there is little known about expressed parent need in the New Zealand context. This exploratory descriptive study involved parents of under five year old children, who had been admitted to a hospital, with one of five acute illnesses. Eighteen parents were surveyed over the telephone. This study found the parents expressed a need for reassurance and advice once home, and that they worried about their child getting sick again. It highlighted gaps in discharge planning and support. None of the parents had received a written discharge plan for their child. Only five parents had received either a contact number for advice or a referral back to their primary care provider. This study found that whilst some parents considered their discharge needs had been met, others considered that they had not. Four local discharge practice opportunities to support these families were recommended, these included, providing parents and caregivers with an individualised written discharge plan, giving a contact number for advice after discharge, offering a follow-up phone call in the first 48 hours, and ensuring that all children have a referral back to their primary health care provider. Areas for further research were highlighted, including the need for a larger study to explore and compare the needs of rural and urban parents, and Maori and Pacific parents.

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.
