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 article provides a background to the development of cognitive therapy and cognitive therapeutic skills with a specific focus on the treatment of a depressive episode. It discusses the utility of cognitive therapeutic strategies to the model of crisis theory and initial crisis assessment currently used by the Community Assessment & Treatment Team of Waitemata District Health Board. A brief background to cognitive therapy is provided, followed by a comprehensive example of the use of the Socratic questioning method in guiding collaborative assessment and treatment of suicidality by nurses during the initial crisis assessment.

Abstract: In 2004, Plunket nurses from eight areas around New Zealand participated in collecting data for a research project on health needs assessment practices. This project aimed to examine risk factors identified by Plunket nurses, what areas of health need considered to be priorities; grading of health needs; and how closely the results of health need assessment aligned with the individual clients' deprivation score. The researchers examine the assessment of health needs against the use of the Deprivation Index, which indicates a specific population in a specific area, as a funding model. This study appeared to show there are two distinct groups of clients assessed as high needs: those with risk factors such as family violence and severe parental mental illness, and who may live in an area of 1-7 deprivation; and those with multiple risk factors which include poverty, low education, and/or reluctance to access services and support, and who usually live in dep 8-10 areas. This research supports the anecdotal evidence that significant health needs exist outside the lower deprivation areas.

Abstract: Examines the pain management practices of nurses, and identifies barriers and facilitators to the assessment and management of pain for older people, within the acute hospital setting.

Abstract: Current New Zealand health policy encourages collaborative health promotion in all sectors of health service delivery. The integrated approach to the acute management of coronary heart disease in a coronary care unit, combining medical therapy and lifestyle change, supports clinical health promotion. The aim of this study was to use the grounded theory approach to discover the main concerns of nurses' promoting health in an acute coronary care setting and to explain the processes that nurses used to integrate health promotional activities into their practice. Seventeen registered nurses from three coronary care units within a large metropolitan city in New Zealand were interviewed. Data were constantly compared and analysed using Glaser's emergent approach to grounded theory.The main concern for nurses promoting health within coronary care was ritualistic practice. In this study, ritualistic practice concerns the medically-based protocols, routines, language and technology that drives nursing practice in coronary care. This concern was resolved via the socio-cultural process of attitudinal shifting that occurs over time involving three stages. The three conceptual categories, environmental pressures, practice reality and responsive action are the main components of the theory of attitudinal shifting. In environmental pressures, nurses experience a tension between specialist medically-dominated nursing practice and the generalist nursing role of promoting health. In practice reality, nurses become aware that the individual needs of patients are not being met. This causes role conflict until the nurse observes colleagues who role model possibilities for practice, working with patients to promote health. Responsive action sees the nurse engaging in self-development, also focusing on the nurse-patient relationship, thereby enabling active patient involvement in individual health-promoting decisions. The author suggests that the findings from this research have implications for nursing practice and education. With the increasing specialisation in nursing practice, these findings may be of interest to nurses working in delegated medical roles where the reality of everyday practice precludes nurses from undertaking their essential nursing role. Health care facilities also need to ensure that there are opportunities for the personal and professional development of nursing staff. The place of health promotion within nursing undergraduate curricula needs to be examined, as many nurses found that they were ill prepared for undertaking health promotional activities.

Abstract: Reports the findings of a review of the literature that sought to identify key barriers for indigenous tertiary nursing students in NZ. Reveals the barriers to recruitment and retention of nursing students, and strategies to overcome them. Stresses the need for partnerships between academic institutes and indigenous communities to ensure the provision of a culturally-safe environment for Maori nursing students.
