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: This study was developed to explore the use of seclusion in an acute in-patient unit for people with mental illnesses. Investigation into this issue was considered important due to an identified large increase in seclusion use over the previous two years. The study used a qualitative research methodology with a descriptive and interpretive approach. Data collection included a retrospective file audit of patients who had been secluded over the past seven years, and one-to-one staff interviews. It also includes the author's personal reflections of seclusion events. The principle reason for using seclusion was violence and aggression in the context of mental illness. It was also used for people who were at risk of, or who had previously absconded from the unit. A recovery approach and the use of the strengths model was fundamental to nurses' way of working with patients in the unit. Nurses believed that the strengths process should be adapted to the person's level of acuity and to their ability to engage in this approach in a tangible way. Seclusion continues to be a clinical management option in the unit that is the subject of this study. However, in many circumstances there are other options that could be explored so that the utmost consideration is given to the dignity, privacy and safety of that person.

Abstract: The aim of this research was to describe what factors contribute to people re-presenting to the emergency department (ED) within one week of a previous visit for intentional self-harm. Objectives identified were to describe the people using demographic and clinical features; describe and evaluate ED management; and identify possible personal or system reasons as to why people re-present to ED within one week. A retrospective observational design was selected for a period of one year. The data was collected from electronic clinical case notes. The sample consisted of 48 people with 73 presentations and re-presentations. Missing data limited the number of inferential analyses. Outcome measures were divided into information regarding the person and the presentation. This study made several discoveries: many representations (55%) occurred within one day; the exact number of people who represented many times to ED is unknown, but is far higher than reported in other studies; fewer support people were present for the second presentation; the documentation of triage and assessments by ED staff was often minimal, though frequently portrayed immense distress of this population; cultural input for Maori was missing; physical health complaints and psychosis were found with some intentional self-harm presentations; challenging behaviours occurred in at least a quarter of presentations; and the medical and mental health inpatient admission rates were approximately 50% higher for second presentations. Recommendations in regard to the use of a triage assessment tool, the practice of reviewing peoples' past presentations and the need for a mental health consultation liaison nurse in ED are made. Staff education, collaboration between services with consumer involvement and further research of this group are required. This study supports the need for holistic and expert care for people who present at emergency departments with intentional self-harm.

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: 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: The objective of this meta-analysis was to assess the effectiveness of pentoxifylline as an adjunct to compression bandaging in the treatment of venous leg ulcers. The CENTRAL registers of the Cochrane Peripheral Vascular Diseases and Wounds Groups were searched – each register is routinely updated by extensive searches of electronic databases, handsearching of relevant journals and conference proceedings, and contact with product companies and experts in the field. The drug's manufacturer was contacted and the references of review articles and all obtained trials were scrutinised for further citations. Randomised controlled trials published in any language comparing pentoxifylline and compression with placebo in adult participants with venous ulceration were included. Trials must have reported a meaningful objective outcome (rates of healing, proportions healed, time to healing). Details from eligible trials (independently selected by two reviewers) were extracted and summarised by one reviewer. A second reviewer independently verified extracted data. Eleven clinical trials were identified. Five trials compared pentoxifylline with placebo (compression standard therapy). Six trials were excluded. Pentoxifylline and compression was more effective than placebo and compression (RR 1.30, 95% C1 1.10-1.54) and was robust to sensitivity analyses. The greater number of adverse effects (46 reports) occurred in the pentoxifylline group, although this was not significant (RR 1.12, 95% C1 0.77-1.62); 34 percent of adverse effects were gastro-intestinal. Seven of 21 reported withdrawals were for adverse effects. In conclusion, pentoxifylline appears an effective adjunct to compression bandaging in the treatment of venous ulcers. The absence of cost-effectiveness data suggests it not be employed as a routine adjunct, but it could be considered as for those patients not responding to compression therapy alone. The majority of adverse effects are likely to be tolerated by patients.

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.
