Abstract: A retrospective descriptive design was used to examine the records of all presentations to the emergency department of patients with COPD over a 3-month period to determine whether there is a subset group of people who present with hypercarbia. There were 114 presentations, amongst those there were 71 individuals, a number presenting more than once within the three months. 80% of the 71 individuals had a smoking history of which 53% were female. Of the 114 presentations, 76 had arterial blood gases taken during their emergency department presentation. Of these 76 presentations 30 had hypercarbia and 46 were non-hypercarbia. These 76 presentations involved 58 individuals, with some individuals presenting five times over the three-month period. Three groups emerged, some who were only hypercarbia (n= 18), some in the non-hypercarbia group (n=35) and 5 individuals who had presentations in both the hypercarbia and non-hypercarbia groups. Data showed that there was no definable subset group of hypercarbia patients within acute exacerbations of COPD presenting to the emergency department according to the variables. However the sample of presentations (with a blood gas) found within the study suffering hypercarbia was much higher (31.1%) than anticipated. Further analysis showed that the hypercarbia group had a significant lower forced expiratory volume in one second (FEV1) and a combination diagnosis of emphysema or asthma and congestive heart failure. An implication to the clinician is that identification of hypercarbia within COPD exacerbation is problematically difficult until the late signs are shown with the individual. By that time effective treatment patterns may have changed from the initial presenting problem. The author concludes that future areas of research within this field needs to lie within the community, and look at when these people start the exacerbation, what leads them to progression presentation to the emergency department, and whether these people are chronic sufferers of hypercarbia or presenting after a period of days exacerbation within their own home.

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 paper presents research findings from a New Zealand study that explored emergency nurses' differentiation of non-cardiac chest pain from panic disorder and raised significant issues in the nursing assessment and management of such clients. The data were gathered from focus group interviews and were analysed thematically. Three themes, prioritising time, managing uncertainty and ambiguity, and the life-threatening lens, were identified. The findings confirm that a panic disorder is not always diagnosed when biomedical assessment is used in isolation from a psychosocial assessment. Emergency nurses are pivotal in reversing the cycle of repeat presenters with non-cardiac chest pain. Recommendations for assessing and managing this complex condition are presented.

Abstract: The aim of this paper is to compare the Emergency Nurse Practitioner role in the UK, Australia and New Zealand. Whilst geographically distant, the role of the Emergency Nurse Practitioner within these three countries shares fundamental similarities, causing the researchers to question, is this a time to implement international standards for the role? The Emergency Nurse Practitioner role in all three countries is gradually establishing itself, yet there are shared concerns over how the role is regulated and deficits in standardisation of scope of practice and educational level. Together these issues generate confusion over what the role embodies. The authors suggest that one method of demystifying the Emergency Nurse Practitioner role would be to progress towards international standards for regulation, education and core components of practice.

Abstract: Pain management practices within emergency departments require a more patient focused approach due to extended waiting times for analgesia. This dissertation questions current methods of providing timely and appropriate delivery of analgesia. Nurses represent the biggest resource in emergency departments therefore are in a position to be able to access patients in a timely fashion. A review of the literature pertaining to nurse initiated analgesia protocols has been evaluated and information relating to efficiency and safety utilised to discuss the processes for planning and implementation of a similar protocol. The author finds that the literature provides no evidence that nurse initiated analgesic practices prior to medical assessment compromises patient safety or delays diagnosis. A discussion of the benefits to patients, nurses and the institution has been included to highlight the appropriateness of extending nursing roles.

Abstract: Family violence is common and there are significant long-term negative health effects from victimisation. Health professionals are now recognised as key providers of family violence intervention. The Hawke's Bay District Health Board HBDHB) launched a Family Violence Intervention Programme in the emergency department in 2002, in accordance with national directives. The Family Violence Intervention Programme includes routine questioning for partner abuse within social history assessments for all women 16 years and over who seek healthcare services. Nurses assumed responsibility for implementing this programme into emergency department practice. Establishing partner abuse screening in practice requires an organisational and attitudinal change. Achieving and sustaining this change can be difficult. Evaluation was considered an essential aspect of the systems approach adopted within the HBDHB Family Violence Intervention Programme to support change. The aim of this study was to identify the enablers and barriers to routine questioning in the emergency department one year after the programme was launched and the strategies to address these barriers. The staff who have responsibility for routinely questioning women were considered well placed to provide this information. The methodology selected was evaluation research using semi-structured interviews. The design included member checking and triangulation of the findings. Eleven emergency department staff members participated in five (two group and three single) interviews. The interviews revealed that routine questioning for partner abuse is difficult in the emergency department setting. Barriers to questioning exist and enablers can eliminate or minimise these. Enablers such as policy and training support routine questioning. Barriers identified included the lack of privacy and time. Participants suggested strategies to overcome these. These barriers, enablers and solutions were either personal or organisational in origin and all had a common theme of safety. An outcome of the study was the development of a model of barriers and enablers to ensure safety when routinely questioning women for partner abuse. This evaluation has utility within the HBDHB as it informs programme progression. However, the evaluation has wider implications. The experiences of the emergency department staff led to the emergence of key themes that may inform the development of comparable programmes. Introducing routine questioning requires a practice change; a multifaceted approach focusing on safety can assist staff to achieve that change.

Abstract: To find an effective approach to managing or reducing waiting times for lower triage category patients processed through one particular metropolitan emergency department, an extensive search of the literature revealed several different patient flow processes. These approaches are discussed, in relation to suitability for the particular emergency department. The history of triage, including how and why it evolved, plus the realities of triage today are explored. Included are case examples of two patients on a journey through the department the way it is presently, and how it could be if particular approaches are introduced. Extending nursing practice by introducing nurse-initiated x-rays at triage and the introduction of a separate stream for minor category patients in a dedicated ambulatory care area is one approach that could improve waiting times for these patients. There would be the added advantage of improving triage compliance figures for category three patients. The additional costs involved in such a process could be offset by improved efficiency in terms of waiting times, improved triage compliance figures, happier patients and clinical staff, and an emptier waiting room.
