Fogarty, K. (2005). The assessment of competence in the novice nurse in the adult intensive care unit. Ph.D. thesis, , .
Abstract: This dissertation explores the assessment of nurses' clinical competence in the adult ICU setting. Specifically, methods for the assessment of competence are critiqued for their practical application to the novice nurse with less than six months experience in ICU. The assessment methods considered are continuous clinical assessment, self-assessment, peer review, objective structured clinical examination (OSCE), portfolio and computer assisted assessment. Several criteria are applied to the methods including the ability of each method to assess skills, knowledge and attitudes or values. Each method is critiqued for its implications in terms of cost and staffing resource, benefits and barriers to implementation. In addition, reliability and validity issues are considered for each method. The outcome of this exploration is the recommendation of a combination of methods; namely, portfolio and OSCE, for the assessment of competence in the ICU novice. The author concludes that this finding enhances current understanding within the ICU specialty of the multidimensional nature of competence assessment.

Fahey, M. (2003). Family centred care in the newborn intensive care unit: Creating a supportive environment. Ph.D. thesis, , .
Abstract: The environment of the Newborn Intensive Care Unit (NICU) is a stressful one for families and is often designed to provide technical care for the infant rather than facilities that would enable and support parental and family participation in infant care. Furthermore, the author notes that the environment of the NICU emerged in literature as an obstacle to meaningful family involvement in care. However, she goes on to say that a philosophy of Family Centred Care in the NICU can offer a framework of care that supports family involvement in the infant's care and family presence in the NICU. It also promotes parental participation in decision-making for the infant and gives recognition to the importance of perspectives provided by the family. This dissertation explores the difficulties associated with the practice of Family Centred Care in the environment of the NICU. It offers recommendations for features of unit design that can promote Family Centred Care by supporting and sustaining the presence of families in the NICU and therefore facilitating their involvement in the care of their infant.

Cook, D. (2006). Open visiting: Does this benefit adult patients in intensive care units? Ph.D. thesis, , .
Abstract: As the healthcare system moves toward a consumer-driven paradigm, visiting hours for family and significant others of the intensive care unit patient have become a topic of interest and discussion. Research since the 1970s has generated controversy and speculation over the ideal visiting practices in the adult intensive care unit. The aim of this dissertation was to examine the benefits for the patient, family members and nurses of appropriate visiting practices within intensive care areas in order to establish if open visiting is the best regime for patients in the adult intensive care unit (ICU). This dissertation explores visiting practices in adult critical care unit settings. Specifically, the benefits of visiting for patients, and the factors that may impede or facilitate visiting practices within the ICU were critically discussed. These factors included the benefits and disadvantages of open visiting, and the nurse as an influential factor in visiting. These areas linked together to form the basis for consideration of visiting in the ICU. Review of existing literature pertaining to visiting in the ICU indicated that patients wanted open visiting hours yet also indicated that they would like some visiting restrictions. Nurses appeared to value family input into care and were aware of patient and family needs, even though they may restrict visiting to suit their own work practices. Family members can provide the patient with psychological support, provide important historical data, assist the nurse with selected aspects of physical care, and actively encourage the patient's efforts to recover. The outcome of this exploration is the recommendation of an open visiting policy tailored to individual patients, as, the author suggests, this would foster nursing practice and ultimately benefit patients and their families.

Evans, S. (2006). Silence kills: Communication around adverse events in ICU. Ph.D. thesis, , .
Abstract: The aim of this dissertation is to assess the preventability or reduction of adverse events in the intensive care unit (ICU) through a literature review. Research shows the ICU is at high risk for errors, nevertheless there is a huge gap between knowing something should be done and applying this knowledge to practice. That being the case, this dissertation identifies and discusses several proven and transferable quality improvement proposals. These include: instituting anonymous error reporting; documentation of a daily goal-of-care; a nurse as ICU team co-ordinator; conflict resolution processes and communication training for all ICU staff. NThe author concludes that nurse-doctor collaboration requires the support of medicine, with recognition of the unique contribution nurses make to patient safety.

Marshall, K. (2007). Enteral nutrition within 72 hours after spinal chord injury: Complexities and complications. Ph.D. thesis, , .
Abstract: Good nutrition is essential following acute spinal cord injury. Poor nutrition can lead to the deleterious effects of protein-calorie induced hypermetabolism and poor functional and rehabilitation outcomes. Nutritional management for patients with acute cervical or high thoracic spinal cord injury admitted to the Canterbury District Health Board's Burwood Spinal Unit and Christchurch Hospital's Department of Intensive Care Medicine (CHDICM) differ. The Burwood Spinal Unit has a delayed approach to nutritional management in contrast to the implementation of early enteral feeding by CHDICM. This prompted a literature review to critically consider the evidence underpinning clinical practice in this field. Literature revealed that nutritional management in the first 72 hours after spinal cord injury is a complex process. The complexities of when to commence, the method of delivering, and the target dose of enteral nutrition in the first 72 hours after spinal cord injury are due to the perceived risk of a spinal ileus and the ensuing, such as adverse effects on abdominal and respiratory function, resulting from enteral feeding intolerance. Literature revealed that delayed nutrition is largely based on expert opinion, while early enteral feeding has limited but stronger scientific research evidence. Nevertheless, it is desirable to use the best evidence currently available to develop, implement and evaluate an evidence-based, protocol driven, clinical pathway for nutritional management of patients within 72 hours of an acute cervical or high thoracic SCI. The author concludes that to ensure an acute spinal cord injury clinical pathway is based on scientific evidence, prospective, multi-centre, randomised controlled trials are needed to substantiate early enteral feeding and identification of the degree of and risk of complications from spinal ileus after acute cervical or high thoracic spinal cord injury.

Brookes, K. (2001). Moving stories from nurses in flight. Ph.D. thesis, , .
Abstract: This thesis contains a collection of stories gifted by four New Zealand Retrieval Team nurses who are experienced in the transport of patients. These nurses are commonly called flight nurses and they assist in the transport of patients via helicopter, fixed-wing aeroplane, large commercial aeroplanes and ambulances. While their practice is not exclusively in the helicopter there is an emphasis on this mode of transport in this thesis. Flight nursing is a scope of nursing practice where the use, and visibility, of nurses' stories is rare. The specific context of this research is positioned in one tertiary intensive care unit in New Zealand but it is anticipated that the stories from four flight nurses and the author's subsequent thoughts on them will resonate with flight nurses in other regions. The stories were collected using a storytelling methodology that has been informed by qualitative and feminist perspectives. The stories were either gathered and shaped using interview and transcription techniques with the storyteller and the researcher, or written by the storyteller. The thesis has been written as a narrative and chronicles the journey to the point of receiving the stories and the lines of inquiry in which they subsequently directed the author. The stories are central to this research and appear in their entirety. The reader is encouraged to create their own meaning from the stories. The stories themselves have several common threads, which are planning, communication, teamwork and the unexpected. The threads underpinning the stories are not unique to flight nursing practice and have been discussed in other scopes of practice. One area the author has chosen to explore in more depth is the impacts of technology, privacy, narrative pedagogy and disenfranchisement on the visibility of flight nurses' stories. The other area she has chosen for discussion is advanced and specialty nursing practice as it relates to flight nurses. As a result of this discussion she proposes her own view for advanced and specialty practice in flight nursing.

Johnson, H. (2008). Clinical trials in the intensive care setting: A nursing perspective. Ph.D. thesis, , .
Abstract: As carers of patients who are clinical research participants, nurses' contribution to the success of clinical trials is acknowledged in the literature. Ethical dilemmas and challenges that clinical trials may present for nurses are also recognised. Although there is some discussion regarding these issues, few studies explore and identify the perceptions of intensive care nurses regarding clinical trials and how they may impact on nursing practice. This thesis explores and describes the viewpoints and experiences of sixty intensive care nurses from a tertiary level referral centre in New Zealand engaged in clinical research activities. The descriptive study utilised a self-administered questionnaire to gather information regarding nurses' roles in clinical trials, associated issues encountered and contributory factors, and the impact of issues on nursing practice, stress and satisfaction levels. Suggestions for potential strategies to minimise the impact of issues on nurses' practice were also sought. Descriptive statistical and content data analyses identified three key areas in which nurses' encounter issues associated with clinical trials and their practice: nurses' workload; ethical concerns; educational preparation and support. The findings indicate that, when issues exist in these areas, routine patient care can be delayed, the enactment of nurses' patient advocacy role can be affected, and nurses' stress and satisfaction levels can be negatively impacted upon. The perceptions of a group of intensive care nurses who are enveloped in the daily balance of patient care, the need for clinical research, and their professional obligations are discussed in this thesis. While the study's findings are reflective of one group of nurses in a distinct practice setting, their experiences can prompt other nurses, research teams and clinical leaders to reflect upon their own clinical research environment.

Evans, S. (2003). Improving nursing care of infants and children ventilated with uncuffed endotracheal tubes. Pediatric Intensive Care Nursing, 4(2), 7.
Abstract: The author draws on her experience as the 'Paediatric Link Nurse' in an Intensive Care Unit (ICU) within a metropolitan area in New Zealand to examine the proposed changes to ventilation practice. Currently, due to ventilator availability and medical and nursing practice, the usual mode of mechanical ventilation is volume-limited with pressure breath triggering. The author suggests this mode can compromise effective ventilation of paediatric patients, due to air leaks around the uncuffed endotracheal tubes of infants and small children. This air leak makes a guaranteed tidal volume almost impossible and can cause ventilator breath stacking and volutrauma. This can impact on the patient's comfort, sedation requirements and airway security, and affects how these patients are nursed. Thus the ventilation of these paediatric patients by the current volume-limiting mode may be not always be optimal for the infant/child. A new ventilator will be available to the unit, with a pressure-controlled, flow breath-triggering mode available. The author critiques the possibility of using this mode of ventilation, suggesting how this will impact on nursing practice in ICU, and of the education and knowledge that will be required. She suggests this change to ventilation practice may improve comfort and safety for the intubated child/infant, through the delivery of an optimal mode of ventilation.

Pirret, A. M. (2007). The level of knowledge of respiratory physiology articulated by intensive care nurses to provide rationale for their clinical decision-making. Intensive & Critical Care Nursing, 23(3), 145–155.
Abstract: The objective of this paper is to outline a study firstly, assessing ICU nurses' ability in articulating respiratory physiology to provide rationale for their clinical decision-making and secondly, the barriers that limit the articulation of this knowledge. Using an evaluation methodology, multiple methods were employed to collect data from 27 ICU nurses who had completed an ICU education programme and were working in one of two tertiary ICUs in New Zealand. Quantitative analysis showed that nurses articulated a low to medium level of knowledge of respiratory physiology. Thematic analysis identified the barriers limiting this use of respiratory physiology as being inadequate coverage of concepts in some ICU programmes; limited discussion of concepts in clinical practice; lack of clinical support; lack of individual professional responsibility; nurses' high reliance on intuitive knowledge; lack of collaborative practice; availability of medical expertise; and the limitations of clinical guidelines and protocols. These issues need to be addressed if nurses' articulation of respiratory physiology to provide rationale for their clinical decision-making is to be improved.

Tweed, C., & Tweed, M. (2008). Intensive care nurses' knowledge of pressure ulcers: Development of an assessment tool and effect of an educational program. American Journal of Critical Care, 17(4), 338–347.
Abstract: The aim of this study was to assess intensive care nurses' knowledge of pressure ulcers and the impact of an educational programme on knowledge levels. A knowledge assessment test was developed. A cohort of registered nurses in a tertiary referral hospital in New Zealand had knowledge assessed three times: before an educational programme, within two weeks after the programme, and 20 weeks later. Completion of the educational programme resulted in improved levels of knowledge. Mean scores on the assessment test were 84% at baseline and 89% following the educational programme. The mean baseline score did not differ significantly from the mean 20-week follow-up score of 85%. No association was detected between demographic data and test scores. Content validity and standard setting were verified by using a variety of methods. Levels of knowledge to prevent and manage pressure ulcers were good initially and improved with an educational programme, but soon returned to baseline.

Rose, L., Nelson, S., Johnston, L., & Presneill, J. J. (2008). Workforce profile, organisation structure and role responsibility for ventilation and weaning practices in Australia and New Zealand intensive care units. Journal of Clinical Nursing, 17(8), 1035–1043.
Abstract: The aim of this research is to provide an analysis of the scope of nursing practice and inter-professional role responsibility for ventilatory decision-making in Australian and New Zealand intensive care units (ICU). Self-administered questionnaires were sent to nurse managers of eligible ICUs within Australia and New Zealand. Survey responses were available from 54/180 ICUs. The majority (71%) were located within metropolitan areas and categorised as a tertiary level ICU (50%). The mean number of nurses employed per ICU bed was 4.7 in Australia and 4.2 in New Zealand, with 69% (IQR: 47-80%) of nurses holding a postgraduate specialty qualification. All units reported a 1:1 nurse-to-patient ratio for ventilated patients with 71% reporting a 1:2 nurse-to-patient ratio for non- ventilated patients. Key ventilator decisions, including assessment of weaning and extubation readiness, were reported as predominantly made by nurses and doctors in collaboration. Overall, nurses described high levels of autonomy and influence in ventilator decision-making. Decisions to change ventilator settings, including FiO(2) (91%, 95% CI: 80-97), ventilator rate (65%, 95% CI: 51-77) and pressure support adjustment (57%, 95% CI: 43-71), were made independently by nurses. The authors conclude that the results of the survey suggest that, within the Australian and New Zealand context, nurses participate actively in ventilation and weaning decisions. In addition, they suggest, the results support an association between the education profile and skill-mix of nurses and the level of collaborative practice in ICU.
