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.

Abstract: This study provides insight into the experience of being an ICU nurse and relative of a critically ill patient. Analysis of data from interviews of four ICU nurses who had experienced having a family member admitted to ICU brought up several themes. These included: a nurses' nightmare, knowing and not knowing, feeling torn, and gaining deeper insight and new meaning. Recommendations for organisational support for ICU nurse/relatives, and education for staff are made, based on the findings.

Abstract: This dissertation considers the implications of the relationship between nurses and the patient's family, when family members visit intensive care units (ICUs) following the acute admission of a relative there. In particular it explores the issues of power and control, nurses might have in this setting, the culture that supports that, and the implications this has for practice in the New Zealand context. A comprehensive literature review on the perspective of nurses in relation to relatives visiting adult intensive care units was conducted. The author concludes that nurses modify policies related to visiting access for family members to suit themselves, and the needs of their patient. Nurses use a variety of tactics to maintain a position of power and control by looking out for themselves first, their patient second, and relatives third. The need of the patient and their families is not well understood by nurses, and nurses feel they have inadequate skills to cope with the needs and stresses of visiting relatives. The author suggests that for nurses to provide family focused care in ICU they must develop a therapeutic relationship with all concerned. ICU nursing culture affects nurses ability to focus on caring for their patients and their families. Nurses in ICU appear to need to maintain power and control over their environment but further research is needed to identify the current situation in New Zealand ICUs.

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.

Abstract: This study is an extension of a previous study by Riker, Picard and Fraser (1999) to determine whether doctors and nurses rate patients similarly using the Sedation-Agitation Scale (SAS) in a natural Intensive Care Units (ICU) setting. The author notes that it is essential to establish whether these different professionals provide consistent scores and have a mutual understanding of the SAS and its constituent levels. This will help ensure that clinical decisions relating to sedation-needs can be made appropriately and consistently. This quasi-experimental reliability study was set in a 12-bed tertiary general ICU in New Zealand. The SAS had recently been introduced into this unit and a convenience sample of 42 nursing and medical staff performed paired ratings on 69 randomly selected adult ICU patients over an eight week time frame. The mean patient age was 58 years, and 79% of patients were on continuous infusions of Propofol. Intubated patients made up 91% of the sample. 74% of patients were given the same SAS score by the doctor-nurse pair. The weighted kappa score for inter-rater agreement was 0.82 indicating very good agreement. Of the 26% of scores where there was a difference, the two readings were only one score apart. Most of the difference occurred around SAS scores of 1-2 and 3-4. Further analysis found no staff or patient variables to be statistically significant in impacting on the ratings. The SAS was found to be a reliable sedation-scoring tool in a general ICU when used by nurses and doctors of varying experience.

Abstract: The author's art project “Posthuman Pathology” is a postmodern examination of the resolutely modernist culture of critical care medicine. She uses conceptual art practices in conjunction with the techniques of anti-aesthetics in order to dismantle, open out and critique ideas which are foundational to the culture of critical care.

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.
