Abstract: With the intention of decreasing emergency department demand, there has been a focus on determining those patients who do not require the services of the emergency department so they can be redirected away to an alternative health care provider or facility. Co-locating an after-hours primary health care facility near to the emergency department is a model under consideration in some district health boards. This model suggests that a substantial proportion of the patients currently managed in the emergency department can be assessed and managed in a general practice setting. It is envisaged that by redirecting the lower acuity patients away from the emergency department, overcrowding will be relieved. This is despite evidence demonstrating that low acuity patients are not the cause of emergency department overcrowding. Moreover, being treated at the emergency department is the only safety net for many people in the community who cannot afford alternative care. This research report discusses the literature regarding the practice of referring or redirecting patients away from the emergency department and the issues associated with this model. In doing this, it looks at the Australasian Triage Scale, the system used to ensure patients are seen in order of clinical urgency, because it has been suggested that this system could be used as a tool to refer patients away from the emergency department. The author concludes that even though some people could be seen by another health care provider, the triage system is not an appropriate tool for achieving this. While it is tempting to believe that patients in the lower triage categories are prime candidates for being referred away, there is evidence from hospital statistics that patients in these categories have a high number of hospital admissions and in-hospital death rates. Additionally, to complicate matters, there is no universal definition of what constitutes an 'appropriate' emergemcy department presentation and no consensus of opinion amongst health professionals in deciding patients' 'appropriateness'. For these reasons it is unethical to expect nurses who administer the triage system to use it for the purpose of referring people away from the emergency department.

Abstract: This thesis explores triage code as a predictor of direct nursing care time, thus its potential usefulness in a model for calculating and allocating nurse requirements in emergency departments. A framework for nursing work is proposed. This framework is based on the works of O'Brien-Pallas, Irvine, Peereboom, and Murray (1997) and Houser (2003). It suggests that the structures of environmental complexity, nursing characteristics, patient nursing complexity, and patient medical condition and severity, impact on the processes of direct and indirect nursing care to affect patient outcomes. A prospective, non-experimental study was undertaken to examine the relationship between direct nursing care time and triage code. Six potential confounding variables were selected for this study: length of stay, age, ethnicity, sex, complaint type, and discharge category. Data were collected for 261 visits over a three day period in one New Zealand emergency department. Patient visits averaged 200 minutes. The mean direct nursing care time per visit was 49 minutes. On average, patients with more urgent triage codes, longer length of stay, or who were not discharged, received more direct nursing care. The model developed predicted 49% of variation in direct nursing care time (p < .05) related to triage code (16%), length of stay (31%) and disposition category (2%). The author suggests that further exploration of the proposed framework has potential to develop a model allowing managers to identify nurse staffing required for optimal nursing care in emergency departments.

Abstract: This thesis explores the nature of the emergency department environment as it continues to challenge emergency nurses to meet the health needs of an increasingly complex emergency department population. The emergency nurse is also facing conflict and challenge with regard to workplace safety and patient rights. The author suggests that, until recently, very little debate or consideration has been given to the moral dilemmas raised in the ability of emergency department staff to deliver timely and appropriate care in an overcrowded environment. She goes on to say that, in New Zealand, there is no national consistency with regard to the waiting crisis, no national guidelines and no national consensus putting the emergency nurse at risk. This thesis argues the need to acknowledge waiting times as a significant safety issue at a national level as increasing waiting times continue to impact on patient outcomes and nursing practice. It challenges current practice, in particular the role of the emergency nurse and the potential to legitimise expansion of the role to improve the patient experience of waiting in the emergency department.

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: 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: This paper outlines some of the special health needs of people from refugee backgrounds who present in the emergency department, and the role of emergency department nurses in improving care for refugee and migrant peoples. Refugees and asylum seekers represent a significant proportion of attendees in emergency departments in Auckland Hospitals. Culture and ethnicity are a major factor to be considered in addressing the health care needs of this population. Other factors such as the physical and psychological sequelae of the refugee experience, health care experience prior to arrival in New Zealand, poverty, language, and the trauma of resettlement also have a major impact on health care seeking behaviours.

Abstract: This clinical case study takes an integrated approach to investigation and critical analysis of the complex physiological and pathophysiological treatment modalities instigated when a patient presents following acute traumatic head injury. A broad overview of the developmental physiology of the brain and an explanation of the mechanism of traumatic brain injury as it relates to alterations in cerebral blood flow, intracranial pressure and cerebral metabolism is presented. The author describes in narrative form the clinical presentation of a patient, her symptoms and initial treatment rationale. It concludes with analysis of the patients initial treatment priorities and symptom management during the first 48 hours of her care.

Abstract: This article looks at the role of technology in nursing, and the interaction between it and human compassion and caring. The interface between critical care technologies and caring is explored, along with the social and political issues facing critical care areas.
