The complex nature of phenomena investigated by nurses demands the use of a multifaceted approach to develop nursing knowledge. Triangulation offers a rigorous methodological framework by which to achieve this aim. The authors describe the historical and philosophical underpinnings of triangulation and outline considerations in relation to applying it in contemporary nursing research.
BACKGROUND: The growing global burden of heart failure (HF) necessitates the investigation of alternative methods of providing co-ordinated, integrated and client-focused primary care. Currently, the models of nurse-coordinated care demonstrated to be effective in randomized controlled trials are only available to a relative minority of clients and their families with HF. This current gap in service provision could prove fertile ground for the expansion of practice nursing [The Nurse in Family Practice: Practice Nurses and Nurse Practitioners in primary health care. 1988, Scutari Press, London: Impact of rural living on the experience of chronic illness. Australian Journal of Rural Health, 2001. 9: 235-240]. AIM: This paper aims to review the published literature describing the current and potential role of the practice nurse in HF management in Australia. METHODS: Searches of electronic databases, the reference lists of published materials and the internet were conducted using key words including 'Australia', 'practice nurse', 'office nurse', 'nurs*', 'heart failure', 'cardiac' and 'chronic illness'. Inclusion criteria for this review were English language literature; nursing interventions for heart failure (HF) and the role of practice nurses in primary care. RESULTS: There is currently a paucity of data evaluating the potential role for practice nurses in a reconfigured, collaborative health care system. Those studies that were identified were, largely, of a descriptive nature. In addition to identifying the practice nurse as a largely unexplored resource, key themes that emerged from the review include: (1) current general practice services face significant barriers to the implementation of evidence-based HF practice; (2) there is considerable variation in the practice nurse role between general practices; (3) there are significant barriers to the expansion of the practice nurse role; (4) multidisciplinary interventions can effectively deliver secondary prevention strategies; (5) practice nurses can potentially facilitate these multidisciplinary interventions; and (6) practice nurses are favorably perceived by consumers although there is some confusion about the nature of their role. CONCLUSION: On the basis of this literature review, practice nurses represent a potentially useful adjunct to current models of service provision in HF management. Further research needs to comprehensively investigate the role of the practice nurse in the Australian context with a view to developing effective and sustainable frameworks for clinical practice. In particular, high-level evidence is required to evaluate the efficacy of the practice nurse role compared to current disease management strategies.
BACKGROUND: The success of biotechnology has created moral and ethical dilemmas concerning end-of-life care in the Intensive Care Unit (ICU). Whilst the competent individual has the right to refuse or embrace treatment, ICU patients are rarely able to exercise this right. Thus, decision-making is left to medical professionals and family/significant others. AIM: This study aimed to explore the lived experience of ICU nurses caring for clients having treatment withdrawn or withheld, and increase awareness and understanding of this experience amongst other health professionals. METHODS: Van Manens' (1990) phenomenological framework formed the basis of this study as it provided an in-depth insight into the human experience. A convenience sample of ten ICU Nurses participated in the study. Conversations were transcribed verbatim and analysed using a process of thematic analysis. RESULTS: Five major themes emerged during the analysis. These were: (1) comfort and care, (2) tension and conflict, (3) do no harm, (4) nurse-family relationships and (5) invisibility of grief and suffering. CONCLUSION: The experience of providing care for the adult having treatment withdrawn or withheld in the ICU represents a significant personal and professional struggle. Improvements in communication between health professionals, debriefing and education about the process of withdrawing or withholding treatment would be beneficial to both staff and families and has the potential to improve patient care and reduce burden on nurses.
BACKGROUND: This study investigated the validity of similar Injury Severity Scores (ISS) generated by different Abbreviated Injury Scale triplets. METHODS: A cohort of trauma patients admitted to a single major trauma service between 1995 and 2002 was studied retrospectively. Mortality rates were compared for groups with identical ISS scores but different triplets. RESULTS: For 2,223 of the 5,946 trauma patients studied, 12 ISS scores were generated by two different Abbreviated Injury Scale triplets. Six of these ISS totals showed significant differences in mortality depending on the triplet source. One of the most striking was ISS 25 (triplet 5,0,0), with a mortality of 20.6%, as compared with 0% for triplet 4,3,0 (p = 0.005). The other statistically significant mortality differences for ISS totals were ISS 27-28.6% (5,1,1) versus 7.4% (3,3,3) (p = 0.05); ISS 29-30.3% (5,2,0) versus 4.6% (4,3,2) (p = 0.002); ISS 33-50% (4,4,1) versus 6.7% (5,2,2) (p = 0.034); ISS 34-45.2% (5,3,0) versus 4.3% (4,3,3) (p = 0.0009); and ISS 41-60% (5,4,0) versus 11.1% (4,4,3) (p = 0.05). CONCLUSIONS: The mortality rates are significantly different between pairs of triplets that generate the same ISS total. Caution must be used in the interpretation of outcomes from ISS values generated by different triplets.
The aim of this systematic review was to critically analyse the literature and present the best available evidence relating to the significance of environmental factors, including equipment, in the transmission of methicillin resistant Staphylococcus aureus (MRSA) to hospitalised patients. Despite an extensive literature search only twenty studies that met the inclusion criteria were identified and analysed. There is evidence that the equipment and the inanimate environment are common reservoirs of MRSA, and that the rate of nosocommial transmission of the organism is influenced by occupancy rate and the design of clinical settings.
This paper seeks to highlight the utility of the Corbin and Strauss Chronic Illness Trajectory Framework in describing recovery from traumatic injury and encourages consideration of its implementation into contemporary trauma nursing (Corbin and Strauss, 1991; 1992). To date, few such frameworks have been proposed to sensitize health professionals to the path of recovery following traumatic injury. Although this framework was initially conceived for use in the domain of chronic illness, the lasting effects of severe traumatic injury have significant parallels to chronic conditions such as stroke (Burton, 2000) and multiple sclerosis (Miller, 1993) to which the framework has previously been applied. This paper demonstrates the Trajectory Framework as a useful structure to potentially enhance the development of post-discharge interventions for trauma survivors and encourages consideration of its implementation into the nursing management of this complex patient group.
Critical reflection upon nursing practice is pivotal in achieving optimal patient outcomes. Implicit in this statement is knowledge about and an understanding of the implementation of evidence-based practice (EBP). This study sought to evaluate baseline knowledge in order to assess and inform a multifaceted intervention to promote EBP in a multi-site facility in Western Sydney, Australia. On two consecutive days in February 2003, a convenience sample of 229 nurses were surveyed using a five-item, investigator developed, written survey tool. Data were analysed using descriptive statistics. Although the majority of respondents (n = 143: 62%) stated that they were aware of EBP, a considerable number (n = 86: 38%) stated they had not previously heard of the term. Of concern, 43% (n = 99) of respondents were unable to identify a source of information and resources about EBP. The results of this observational, descriptive survey underscore the importance of ongoing strategic interventions to improve knowledge, access and implementation of EBP amongst clinical nurses. This study also provides baseline data upon which to evaluate local interventions to promote knowledge of EBP amongst clinicians.
BACKGROUND: Contemporary health care systems are constantly challenged to revise traditional methods of health care delivery. These challenges are multifaceted and stem from: (1) novel pharmacological and non-pharmacological treatments; (2) changes in consumer demands and expectations; (3) fiscal and resource constraints; (4) changes in societal demographics in particular the ageing of society; (5) an increasing burden of chronic disease; (6) documentation of limitations in traditional health care delivery; (7) increased emphasis on transparency, accountability, evidence-based practice (EBP) and clinical governance structures; and (8) the increasing cultural diversity of the community. These challenges provoke discussion of potential alternative models of care, with scant reference to defining what constitutes a model of care. AIM: This paper aims to define what is meant by the term 'model of care' and document the pragmatic systems and processes necessary to develop, plan, implement and evaluate novel models of care delivery. METHODS: Searches of electronic databases, the reference lists of published materials, policy documents and the Internet were conducted using key words including 'model*', 'framework*', 'models, theoretical' and 'nursing models, theoretical'. The collated material was then analysed and synthesised into this review. RESULTS: This review determined that in addition to key conceptual and theoretical perspectives, quality improvement theory (eg. collaborative methodology), project management methods and change management theory inform both pragmatic and conceptual elements of a model of care. Crucial elements in changing health care delivery through the development of innovative models of care include the planning, development, implementation, evaluation and assessment of the sustainability of the new model. Regardless of whether change in health care delivery is attempted on a micro basis (eg. ward level) or macro basis (eg. national or state system) in order to achieve sustainable, effective and efficient changes a well-planned, systematic process is essential.
