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: The aim of this research was to explore patients' educational experiences and the usefulness and benefits of this health education in the rehabilitation period, when undertaking a total joint replacement. An exploratory, qualitative descriptive study method was used to describing patients' experiences of health education. Five participants, convenience sampled, were interviewed eight to twelve weeks post surgery following unilateral total joint replacement in a tertiary hospital. Participants valued the education they received pre operatively, which included written material, video and individual interaction with varied health professionals. Although this was provided in a timely manner, evidence showed limited post operative reinforcement and follow up of given education and preparation for discharge. Three 'partnership' themes were identified from data, Communicative, Subservient and Knowledge. 'Communicative Partnership' conceptualised the participants' experiences of the nurse-patient relationship, whilst 'Subservient Partnership' captured the participants' experiences of 'being' patients. 'Knowledge Partnership' combined the participants' ideas about knowledge and their retention of this knowledge to assist with their rehabilitation post surgery. The needs and experiences of patients after total joint replacement reflect on transitional change – changes in roles, behaviour, abilities and relationships. Educational contents need to reflect a realistic recovery process to assist with this transitional period, delivered by health care professionals in a manner best suited for patients.

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: 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.

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.
