Abstract: A dissertation submitted in partial fulfilment of the requirements of the degree of Master of Nursing at Otago Polytechnic, Dunedin, New Zealand.
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. Analysis of the growing body of research can now be reviewed to enable existing visiting policies to be revised.

Abstract: The objectives of this research were to determine how many registered nurses are working as 'responsible clinicians', under what phases of the legislation they are functioning, and to describe the enabling processes and barriers to nurses undertaking this statutory role. An anonymous descriptive survey was distributed to the 11 nurses who were currently responsible clinicians as well as five senior nurses selected from each of the 21 district health boards and the Auckland Regional Forensic Psychiatry Services (n=121). The response rate was 88.4% (n=107). The survey questioned respondents on statutory roles currently undertaken. Respondents were asked whether the responsible clinician role was a legitimate one for nurses and whether they were motivated to attain it. They were also asked which competencies of the role they believed they met, their perceptions of credentialing processes and the educational requirements needed to achieve the role. Of the approximately 395 responsible clinicians nationally, 11 (2.8%) are nurses. Most nurses viewed the role as legitimate. However, many were unaware of competencies for the role and credentialing processes, and were somewhat ambivalent about achieving the role due to current workload, role conflict and lack of remuneration. Competency deficits were highlighted. The authors conclude that there are grounds to encourage nurses as responsible clinicians given the intent of the legislation. This will require the promulgation of appropriate mental health policy, and a concerted effort by major stakeholders in mental health service delivery.

Abstract: The low numbers of nurses attracted to work in mental health is a concern particularly with the increased demand for mental health services. Strategies are required to increase recruitment to this less popular area of nursing to ensure that a high quality of care is provided for people suffering from mental illness. The World Health Organisation is aware that this area of health has been neglected and that it is time to promote mental health. This study aimed to examine the influences involved in nurses choosing to work in this area. A descriptive survey using a questionnaire was given to seven groups of new graduates enrolled in the New Graduate Mental Health Nursing programme through five educational institutes. At the time of writing there were no published studies around this topic in New Zealand. This study will attempt to inform nurses, the Nursing Council of New Zealand, tertiary institutions and the government of New Zealand that there is evidence of a need to develop and change practices to address the predicted workforce decline.

Abstract: A community based registered nurse from Waikato District Health Board's Older Persons Assessment Team (OPAT) presents her experiences of working with older people with dementia. She uses a case study approach to highlight the issue of wandering, behaviour which can be difficult to modify and can cause carer distress. She outlines a team approach to the condition which requires good communication and co-ordination. Key aspects of management included a risk assessment plan, support for caregivers, and encouraging activity.

Abstract: The prevalence of allergic disease has increased significantly in western countries over the last decade. However, the author points to the availability of specialist allergy services in New Zealand being limited to the large cities, resulting in a lack of, or fragmentation of, the allergy-related services in smaller regions. As a public health nurse in Otago working with a rising number of families with severely food allergic children, the author had become aware of the challenges many parents face in accessing accurate information about their child's allergy and the negative impact this has had on them and their child. The purpose of this dissertation is to explore how an Allergy Nurse Specialist (ANS) led service could improve the experiences and health outcomes of the families and children with severe food allergies living in Otago. A critical analysis of the literature on allergy nursing, advanced nursing roles, and related food allergy issues was conducted and applied to the Otago region. Drawing on the 'Nurse with a Special Interest in Allergy' model of nurse-led allergy care outlined by Cross (2005) and the existing Otago District Health Board's (2004) clinical nurse specialist role, the author proposes that an ANS-led model of care, incorporating advanced nursing practice, primary care access and multidisciplinary collaboration could complement the existing allergy related services in Otago. The focus of the ANS's care will be on facilitating timely access to accurate assessment and advice for families regarding the management of their child's food allergies.

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 reports on a scholarly journey to better understand the processes of clinical decision-making by nurses. It begins by identifying the various terms used to describe a clinical decision, its components and the contexts within which clinical decisions are made. Two philosophies of decision-making are summarised. Some insight into the history of the phenomenological and the rationalist theories of decision-making is offered. The author notes that it became evident that both of these theories are applicable to all nurses and their clinical decision making competencies. Four studies that were undertaken to analyse the decision-making methods of nurse practitioners are critiqued. Of the studies two are British, one is American and one is Australian. The author has summarised the combined findings that identified that the nurses were using a blend of decision-making processes that involved rational decision making as well as the use of intuition. The studies identified that sound clinical decision-making is determined by appropriate educational and clinical preparation and supported by a formal mentoring process and the use of critical reflective practice. In conclusion, the author reflects on her knowledge of decision making prior to embarking on the dissertation and states her intent to facilitate and support advanced decision-making by her colleagues. She goes on to say that uppermost is the need for an institutional and managerial environment that encourages advanced and independent decision-making by nurses.

Abstract: This study explores how registered nurses working within the acute surgical ward environment of a New Zealand hospital communicate changes in a patient's condition. The purpose of this research study was to examine the processes, communication techniques and behaviours that nurses use, in order to determine the critical requirements for registered nurses to effectively communicate changes in patients' conditions to doctors. The critical incident technique developed by Flanagan (1954) was adapted and used to explore incidents that occurred when six registered nurses working in acute surgical wards communicated a change in a patient's condition to a doctor. Communication is an integral part of everyday activity. This study has shown an assessment process occurs before communication can take place. A nurse's concern for a patient's condition initiates the assessment process. A judgement is formed from the nurse's concern that a patient's condition has changed. Judgements take into account multiple ways of knowing including pattern recognition, empirical knowing and intuition. Institutional protocols also affect judgements and the ability of a nurse to ensure support is received for the patient's well being. The communication process is initiated for two reasons, to support the patient, and to support the nurse in providing care for the patient. Significant in determining the need for support is the action required that might be outside the nurse's scope of practice. The response should address the nurse's concern and take into account the importance of the relationship, trust between all parties, respect of each other's positions and knowing team members and their capabilities. Understanding these aspects of the communication process should enhance nurses and doctors abilities to effectively communicate regarding a change in a patient's condition.
