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 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.

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: In New Zealand, the physical assessment of a patient has traditionally been the domain of the medical profession. Recent implementation of advanced practice roles has expanded the scope of practice and nurse practitioners may now be expected to perform physical assessments. The aim of this literature review was to discover what could be learnt from the experiences of Western countries. Nurses from the USA, Canada and Australia readily incorporate physical assessment skills into their nursing practice as a component of health assessment. The international literature identified that any change to the nurse's role in health assessment, to include physical assessment skills, requires strategies that involve the regulatory, educational and practice components of nursing.

Abstract: In 2004, Plunket nurses from eight areas around New Zealand participated in collecting data for a research project on health needs assessment practices. This project aimed to examine risk factors identified by Plunket nurses, what areas of health need considered to be priorities; grading of health needs; and how closely the results of health need assessment aligned with the individual clients' deprivation score. The researchers examine the assessment of health needs against the use of the Deprivation Index, which indicates a specific population in a specific area, as a funding model. This study appeared to show there are two distinct groups of clients assessed as high needs: those with risk factors such as family violence and severe parental mental illness, and who may live in an area of 1-7 deprivation; and those with multiple risk factors which include poverty, low education, and/or reluctance to access services and support, and who usually live in dep 8-10 areas. This research supports the anecdotal evidence that significant health needs exist outside the lower deprivation areas.

Abstract: The aim of this paper is to detail the practical application of the Delphi technique as a culturally and clinically valid means of accessing expert opinion on the importance of clinical criteria. Reference is made to a bicultural New Zealand mental health nursing clinical indicator study that employed a three-round reactive Delphi survey. Equal proportions of Maori and non-Maori nurses (n = 20) and consumers (n = 10) rated the importance of 91 clinical indicator statements for the achievement of professional practice standards. Additional statements (n = 21) suggested by Delphi participants in round 1 were included in subsequent rounds. In round 2, participants explained the rating they applied to statements that had not reached consensus in round 1, and summarised responses were provided to participants in round 3. Consensus was considered to have been achieved if 85% of round 3 ratings lay within a 2-point bracket on the 5-point Likert-scale overall, or in one of the Maori nurse, non-Maori nurse, or consumer groups. A mean rating of 4.5 after round 3 was set as the importance threshold. Consensus occurred overall on 75 statements, and within groups on another 24. Most statements (n = 86) reached the importance benchmark. The authors conclude that when rigorous methods of participant selection, group composition, participant feedback, and determination of consensus and importance are employed, the Delphi technique is a reliable, cost-effective means of obtaining and prioritising experts' judgements.

Abstract: This paper explores, through the use of a case study, an evidence-based diagnostic reasoning process utilising the framework followed by Dains, Baumann and Scheibel (1998). This framework, as described by these authors, involves an inductive process of reasoning, which leads to formulation of a hypothesis that is then analysed using an evidence-based approach. From this analysis, a likely diagnosis can be made and appropriate therapeutic intervention initiated. This research demonstrates that although an evidence-based approach is the ideal, sometimes clinical intuition is equally important to the clinical outcome.
