Abstract: The objective of this paper is to outline a study firstly, assessing ICU nurses' ability in articulating respiratory physiology to provide rationale for their clinical decision-making and secondly, the barriers that limit the articulation of this knowledge. Using an evaluation methodology, multiple methods were employed to collect data from 27 ICU nurses who had completed an ICU education programme and were working in one of two tertiary ICUs in New Zealand. Quantitative analysis showed that nurses articulated a low to medium level of knowledge of respiratory physiology. Thematic analysis identified the barriers limiting this use of respiratory physiology as being inadequate coverage of concepts in some ICU programmes; limited discussion of concepts in clinical practice; lack of clinical support; lack of individual professional responsibility; nurses' high reliance on intuitive knowledge; lack of collaborative practice; availability of medical expertise; and the limitations of clinical guidelines and protocols. These issues need to be addressed if nurses' articulation of respiratory physiology to provide rationale for their clinical decision-making is to be improved.

Abstract: As carers of patients who are clinical research participants, nurses' contribution to the success of clinical trials is acknowledged in the literature. Ethical dilemmas and challenges that clinical trials may present for nurses are also recognised. Although there is some discussion regarding these issues, few studies explore and identify the perceptions of intensive care nurses regarding clinical trials and how they may impact on nursing practice. This thesis explores and describes the viewpoints and experiences of sixty intensive care nurses from a tertiary level referral centre in New Zealand engaged in clinical research activities. The descriptive study utilised a self-administered questionnaire to gather information regarding nurses' roles in clinical trials, associated issues encountered and contributory factors, and the impact of issues on nursing practice, stress and satisfaction levels. Suggestions for potential strategies to minimise the impact of issues on nurses' practice were also sought. Descriptive statistical and content data analyses identified three key areas in which nurses' encounter issues associated with clinical trials and their practice: nurses' workload; ethical concerns; educational preparation and support. The findings indicate that, when issues exist in these areas, routine patient care can be delayed, the enactment of nurses' patient advocacy role can be affected, and nurses' stress and satisfaction levels can be negatively impacted upon. The perceptions of a group of intensive care nurses who are enveloped in the daily balance of patient care, the need for clinical research, and their professional obligations are discussed in this thesis. While the study's findings are reflective of one group of nurses in a distinct practice setting, their experiences can prompt other nurses, research teams and clinical leaders to reflect upon their own clinical research environment.

Abstract: This article explores the application of professional practice models in nursing. Particular reference is made to the magnet hospital model and the concept of shared governance. Key principles from these models are explored in relation to the implementation of a professional practice model in an intensive care environment. Historical, cultural and professional factors that may be seen as barriers to the implementation of this professional practice model are also explored. In conclusion, the article identifies recommendations that may contribute to a successful implementation and duration of a model in practice.

Abstract: 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. The aim of this dissertation was to examine the benefits for the patient, family members and nurses of appropriate visiting practices within intensive care areas in order to establish if open visiting is the best regime for patients in the adult intensive care unit (ICU). This dissertation explores visiting practices in adult critical care unit settings. Specifically, the benefits of visiting for patients, and the factors that may impede or facilitate visiting practices within the ICU were critically discussed. These factors included the benefits and disadvantages of open visiting, and the nurse as an influential factor in visiting. These areas linked together to form the basis for consideration of visiting in the ICU. Review of existing literature pertaining to visiting in the ICU indicated that patients wanted open visiting hours yet also indicated that they would like some visiting restrictions. Nurses appeared to value family input into care and were aware of patient and family needs, even though they may restrict visiting to suit their own work practices. Family members can provide the patient with psychological support, provide important historical data, assist the nurse with selected aspects of physical care, and actively encourage the patient's efforts to recover. The outcome of this exploration is the recommendation of an open visiting policy tailored to individual patients, as, the author suggests, this would foster nursing practice and ultimately benefit patients and their families.

Abstract: Grounded theory methodology has guided the grounded theory methods used to explore the acute care paediatric nurses' perspective of what they do when a child has had a severe accident. The research was initiated from the experience of nursing children in the context of a rehabilitation centre and wondering how acute care nurses promoted a child's recovery after a severe unintentional injury. Many avenues were used to search international and New Zealand literature but the scarcity of literature related to what acute care paediatric nurses do was evident. Nursing children in the acute care ward after a severe accident is complex. It encompasses nursing the family when they are experiencing a crisis. It is critical that the acute care nurse monitors and ensures the child's physiological needs are met, and the nurse “works with” the child to maintain and advance medical stability. Nursing interactions are an important part of “working with”, communication is the essence of nursing. This research has focussed on the nurses' social processes whilst caring for the physical needs of the child and interacting with the family and multidisciplinary team when appropriate. An effective working-relationship with a nurse and family is founded on trust. Grounded theory methods supported the process of exploring the social processes of “building trust” whilst “working with” families in a vulnerable position. Nurses rely on rapport to be invited into a family's space to “work with” and support the re-establishment of the parenting role. The “stepping in and out” of an effective working-relationship with a family is reliant on trust. Nurses build trust by spending time to “be with”, using chat to get to know each other, involving and supporting the family to parent a “different” child and reassuring and giving realistic hope to help the child and parents cope with their changed future. A substantive theory of the concept of “building trust to work with” has been developed using grounded theory methods. The theory has been conceptualised using the perspective of seven registered nurses working in paediatric acute care wards that admit children who have had a severe traumatic accident.

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: Making the transition to an area of specialist nursing practice is challenging for both the learner and staff who are responsible for education and skill development. This study uses grounded theory methodology to explore the question: “How do nurses learn critical care nursing?” The eight registered nurses who participated in this study were recruited from a range of intensive care settings. The criteria for inclusion in the study included the participant having attained competency within the critical care setting. Data was collected from individual interviews. This study found that nurses focus on two main areas during their orientation and induction into critical care nursing practice. These are learning to do (skill acquisition) and learning to be (professional socialisation). The process of transition involves two stages: that of learning to do the tasks related to critical care nursing practice, and the ongoing development of competence and confidence in practice ability. The relationship of the learner with the critical care team is a vital part of the transition to competency within the specialist area. This study identifies factors that influence the learner during transition and also provides an understanding of the strategies used by the learners to attain competency. These findings are applicable to educators and leaders responsible for the education and ongoing learning of nurses within critical care practice. The use of strategies such as simulated learning and repetition are significant in skill acquisition. However attention must also be paid to issues that influence the professional socialisation process, such as the quality of preceptor input during orientation and the use of ongoing mentoring of the learner.
