Abstract: A retrospective descriptive design was used to examine the records of all presentations to the emergency department of patients with COPD over a 3-month period to determine whether there is a subset group of people who present with hypercarbia. There were 114 presentations, amongst those there were 71 individuals, a number presenting more than once within the three months. 80% of the 71 individuals had a smoking history of which 53% were female. Of the 114 presentations, 76 had arterial blood gases taken during their emergency department presentation. Of these 76 presentations 30 had hypercarbia and 46 were non-hypercarbia. These 76 presentations involved 58 individuals, with some individuals presenting five times over the three-month period. Three groups emerged, some who were only hypercarbia (n= 18), some in the non-hypercarbia group (n=35) and 5 individuals who had presentations in both the hypercarbia and non-hypercarbia groups. Data showed that there was no definable subset group of hypercarbia patients within acute exacerbations of COPD presenting to the emergency department according to the variables. However the sample of presentations (with a blood gas) found within the study suffering hypercarbia was much higher (31.1%) than anticipated. Further analysis showed that the hypercarbia group had a significant lower forced expiratory volume in one second (FEV1) and a combination diagnosis of emphysema or asthma and congestive heart failure. An implication to the clinician is that identification of hypercarbia within COPD exacerbation is problematically difficult until the late signs are shown with the individual. By that time effective treatment patterns may have changed from the initial presenting problem. The author concludes that future areas of research within this field needs to lie within the community, and look at when these people start the exacerbation, what leads them to progression presentation to the emergency department, and whether these people are chronic sufferers of hypercarbia or presenting after a period of days exacerbation within their own home.

Abstract: The delivery of palliative care within contemporary New Zealand society is discussed, in the light of the recent publication of The New Zealand Palliative Care Strategy (2001). The viewpoint taken is largely descriptive rather than prescriptive, being based on a literature survey of international research and academic theory, which is also informed by the author's professionally gained knowledge. Four different perspectives, comprising a mix of providers and recipients of care are investigated: those of central government planning; specialist palliative care units; aged-care complexes; and patients, family and whanau. As an area of healthcare which current demographic projections indicate will become increasingly significant, the provision of palliative care to residents of and patients within aged-care complexes receives special attention. A metaphor of “parallel travellers” on “parallel journeys” is used to provide a thematic basis to the paper. The lived experiences and perceptions of each group of “parallel travellers” are explored. Difficulties in defining and evaluating palliative care, the implications of main-streaming, the scope of palliative care provision, the educative role of specialist palliative care providers and the current focus on mechanistic outcome measures are discussed. It is contended that the values and goals, both explicit and implicit, of the four specified groups may not at present be sufficiently congruent to optimise the effective provision of palliative care from the point of view of all concerned. While adequate resourcing and a genuinely collaborative approach among healthcare providers are both acknowledged to be critical, the potential for palliative care nurse practitioners to be appointed to the role of “care co-ordinator” alluded to within The New Zealand Palliative Care Strategy (2001), is also seen as pivotal. Insights from a postmodern perspective are offered as one possible way of achieving greater congruence.

Abstract: This thesis explores the issues surrounding the elderly remaining in their own environment and why remaining 'at home' becomes so essential for them. There are many elderly people who have moved to residential care settings on the advice of others. The author explores the implications of such moves through the stories of several elderly persons, and her own experiences as a nurse working with the elderly in institutional care.

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 observational study analyses the responses of 38 nurses from two similar units that use different patient handling systems to test the reliability and validity of the Safe Patient Handling Survey (TM) SPH Survey(TM), a perception survey and improvement tool for employees and employers. Currently there is a lack of tools for evaluating patient handling systems. The survey contains 55 questions divided into 6 clusters, staff and patient injury and violence questions, and picture questions depicting unsafe techniques. The data were analysed to see how the SPH Survey(TM) scores correlate with incidents, and its ability to detect differences between the two units. The results of the Pearson and Cronbach(TM) alpha tests show strong reliability, validity and consistency of the SPH Survey(TM). ANOVA comparison of means and Spearman(TM) rho tests shows that higher (better) scores on the SPH Survey(TM) clusters correlate with lower numbers of patient injuries, lower reports of verbal and physical violence episodes, and lower staff injuries. Differences were detected between the units with Unit 2 scoring higher than Unit 1 in all SPH Survey(TM) clusters and scoring lower in staff and patient injuries and violence incidents. Although the analysis was limited by the small sample size, the study has created a sound basis for further investigation. The SPH Survey(TM) is shown to be an easy way to reliably evaluate patient handling systems and workplace culture, target improvement initiatives, and continually monitor the level of patient handling risk in the workplace. Low-risk patient handling gives health care providers the means to focus on delivering high quality patient care, without endangering their own health and well-being.

Abstract: This study drew upon the theoretical insights of Michel Foucault to provide a discursive analysis of the term euthanasia, and the issues surrounding the “right-to-die”. It involved an analysis of primary texts from; nursing, general, and legal literature as well as the media between the years 2002-2004. Drawing upon data researched, the study analyses the main discourses regarding the practice of euthanasia for terminally ill individuals. The two competing discourses that emerged were what the author termed the sanctity-of life-discourse and the right-to-die discourse. The aim of the study was to uncover the discourses understanding of “truth” regarding the right-to-die. The analysis revealed that a small percentage of cancer sufferers (5%) die with their pain insufficiently treated and the right-to-die discourse claims that no individual should have to suffer needlessly, asserting the individuals right to autonomy. Directly opposing this is the sanctity-of life-discourse which states all life is sacred and nothing can justify euthanasia as an acceptable practice in society. These findings indicate the need for effective palliative care and pain management when caring for the terminally ill individual. The legal, ethical and moral implications of euthanasia are many and this study discusses the effects these may have on health professionals involved with the care of terminally ill patients. The study revealed an increasing deployment of the right-to-die discourse in the media and revealed concerns regarding the nursing profession's lack of preparation to deal with euthanasia if it becomes a legal option in end of life care.

Abstract: This paper is an analysis of the cultural and traditional factors that the author presents as essential considerations in the treatment of Samoan people who have been diagnosed with a mental illness. Just as important to any clinical diagnosis, is the spiritual nature of Samoan culture and traditions, which inform belief systems. A full understanding of these will explain how the traditional beliefs and cultural values of Samoan people have an impact on their perception of mental illness, its causes and cures. The thesis places emphasis on 'ma'i -aitu', the Samoan term for most ailments pertaining to the mind or psyche. The focus is on defining 'ma'i -aitu' as part of a Samoan world view and likewise a description of a similar type of manifestation in the Papalagi (western) context of a psychiatric disorder and how treatment and management is usually undertaken. The issues addressed in this paper aim to highlight the Samoan client's world view from a Samoan perspective of mental illness which then poses the question of how they can be managed holistically and appropriately under the Papalagi medical system. Furthermore, it questions if the traditional belief system of Samoans run deeper than originally thought and can the replacement thereof by a foreign culture be responsible for the increased mental problems in Samoans living in New Zealand? This paper emphasises the importance of integrating the western medical model and Samoan health models, for appropriate mental health service delivery to Samoan people.
