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 investigates the way that medical, nursing and institutional discourses construct knowledge in the specific context of Not-for-resuscitation (NFR)in a New Zealand general hospital where NFR guidelines are available in the wards and from the regional ethics committee. The thesis argues that there are ranges of techniques that staff use to construct NFR knowledge, enacted through various forms of speech and silence, which result in orderly and disorderly experiences for patients nearing death. The study was conducted through a critical analysis of the talk of health professionals and the Chairperson of the Regional Ethics Committee.

Abstract: This study used a non-experimental correlational design to research the relationship between the experience of the nurse, with the application of continuous positive airway pressure therapy (CPAP) to patients presenting to a metropolitan emergency department with cardiogenic pulmonary oedema (CPO), and to establish what difference, if any, CPAP made to outcomes. A retrospective audit of records was used to extract data on all 54 patients that received CPAP over a 12-month period. The primary outcome measures were off CPAP within two hours, transfer to intensive care unit or cardiac care unit, and secondary outcome measures were length of hospital stay and death. There was a trend towards more experienced nurses attending patients who required immediate treatment or treatment within 10 minutes. These patients were more likely to be recognised at triage as requiring CPAP therapy. The early application of CPAP reduced hospital mortality, length of stay, and the need for intubation and ventilation. Attention needs to be given on how best to educate nurses so that more patients presenting with acute respiratory failure can benefit from nurses' decision-making regarding the commencement of CPAP.

Abstract: The authors share the evolution of innovative ways to explore, 'unpack' and re-frame clinical issues that exist in everyday practice. The elements of these processes, which they call 'puzzling practice', and the techniques associated with them, were delineated over a two year period by the authors using action theory based processes. The authors have evolved several different frameworks for 'puzzling practice' which they draw on and use in their practice development work and in research practice. This paper pays attention to a particular form of puzzling practice that they found to be useful in assisting individual clinicians and teams to explore and find workable solutions to practice issues. In this example 'puzzling practice' uses seven different elements; naming the issue; puzzling the issue; testing the puzzle; exploring the heart of out practice; formulating the puzzle question; visualising the future; and generating new strategies for action. Each of the elements is illustrated by the story and the key foundations and ideas behind each element is explored.

Abstract: The author explores possible approaches to the ethical dilemma confronting nurses of critically ill premature infants with an uncertain or futile outcome despite aggressive neonatal intensive care. A case history illustrates the issues. The morality of nursing decisions based on deontological and utilitarian principles is examined, as are the concepts of beneficence and non-maleficence. A fusion of virtue ethics and the ethic of care is suggested as appropriate for ethical decision-making in the neonatal intensive care environment.

Abstract: This paper reports on a literature review that examines how health professionals (mainly nurses) recognise the signs of physical deterioration in their patients. It includes discussion of how nurses' clinical decision making skills influence how physical deterioration is identified and determines what changes in the delivery of care could have an impact on emergency department patients at risk of life threatening deterioration.

Abstract: The aim of this study was to test the hypothesis that triaging certain emergency department patients through a rapid assessment clinic (RAC) improves the waiting times, and times in the department, for all patients presenting to the emergency department. For ten weeks an additional nurse and doctor were rostered. On the odd weeks, these two staff ran a RAC and on even weeks, they did not, but simply joined the other medical and nursing staff, managing patients in the traditional way. During the five weeks of the RAC clinic a total of 2263 patients attended the emergency department, and 361 of these were referred to the RAC clinic. During the five control weeks a total of 2204 patients attended the emergency department. There was no significant difference in the distribution across triage categories between the RAC and non-RAC periods. The researchers found that the rapid management of patients with problems which do not require prolonged assessment or decision making, is beneficial not only to those patients, but also to other patients sharing the same, limited resources.
