Predictors of the attitudinal and health outcomes of aged care nurses

This study examines the predictive capacity of the Demand-Control-Support (DCS) model in combination with organizational justice variables on attitudinal- and health-related outcomes for aged care nurses. Multiple regression analyses of aged care nurses (n=168) from a medium to large Australian healthcare organization. The DCS model explains the largest amount of variance across both the attitudinal and health outcomes with 27% of job satisfaction and 44% of organizational commitment, and 33% of psychological distress and 35% of wellbeing, respectively. Additional variance was explained by the justice variables for job satisfaction, organizational commitment and psychological distress. The addition of the organizational justice variables to the DCS model proved to be a valuable step in understanding the work conditions of aged care nurses. The inclusion of curvilinear effects clarified the potentially artefactual nature of certain interaction variables. The results provide practical implications for managers of aged care nurses in developing and maintaining levels of job control, support and fairness, as well as monitoring levels of job demands. The results particularly highlight the importance of the nurses’ supervisor.

Neck muscle activation and head postures in common high performance aerial combat maneuvers

Introduction: Neck injuries are common in high performance combat pilots and have been attributed to high gravitational forces and the non-neutral head postures adopted during aerial combat maneuvers. There is still little known about the pathomechanics of these injuries.

Methods: Six Royal Australian Air Force Hawk pilots flew a sortie that included combinations of three +Gz levels (1, 3, and 5) and four head postures (Neutral, Turn, Extension, and Check-6). Surface electromyography from neck and shoulder muscles was recorded in flight. Three-dimensional measures of head postures adopted in flight were estimated postflight with respect to end-range of the cervical spine using an electromagnetic tracking device.

Results: Mean muscle activation increased significantly with both increasing +Gz and non-neutral head postures. Check-6 at +5 Gz (mean activation of all muscles = 51% MVIC) elicited significantly greater muscle activation in most muscles when compared with Neutral, Extension, and Turn head postures. High levels of muscle co-contraction were evident in high acceleration and non-neutral head postures. Head kinematics showed Check-6 was closest to end-range in any movement plane (86% ROM in rotation) and produced the greatest magnitude of rotation in other planes. Turn and Extension showed a large magnitude of rotation with reference to end-range in the primary plane of motion but displayed smaller rotations in other planes.

Discussion: High levels of neck muscle activation and co-contraction due to high +Gz and head postures close to end range were evident in this study, suggesting the major influence of these factors on the pathomechanics of neck injuries in high performance combat pilots.

Blood glucose meters : an independent head to head comparison

A new generation of blood glucose meters is now available for use by people with diabetes and health professionals, but little independent evaluation data is available. Previous models are prone to a variety of errors. We compared the accuracy, precision and features of the six latest meters available in Australia as of 1996. Meters studied were the Mini-Accutrend and Advantage (Boehringer Mannheim), Precision QID and Companion 2 (MediSense), Glucometer Elite (Bayer) and Lynx (National Diagnostic Products). We measured the blood glucose levels of 50 people with diabetes with these meters, and compared them to a reference method (YSI glucose analyser). Error grid analysis confirmed that accuracy of all meters was sufficient for their intended use as patient monitors. Precision was assessed using 25 samples from control solutions provided for each meter, and the coefficient of variation calculated. Improvements in strip and meter technology in some models have increased ease of use and reduced the likelihood of user error. This study, when considered with individual preferences for various features and price should assist patients in choosing a new blood glucose meter.

Patients and nurses' perspective on oxygen therapy : a qualitative study

Aim. This paper is a report of a study to describe patients' and nurses' perspectives on oxygen therapy.
Background. Failure to correct significant hypoxaemia may result in cardiac arrest, need for mechanical ventilation or death. Nurses frequently make clinical decisions about the selection and management of low-flow oxygen therapy devices. Better understanding of patients' and nurses' experiences of oxygen therapy could inform clinical decisions about oxygen administration using low-flow devices.
Methods. Face-to-face interviews with a convenience sample of 37 adult patients (17 cardio-thoracic: 20 medical surgical) and 25 intensive care unit nurses were conducted from February 2007 to September 2007. Interviews were audio-taped, transcribed verbatim and then analysed using a thematic analysis approach.
Findings. The patients identified three key factors that underpinned their compliance with oxygen therapy: (i) device comfort; (ii) ability to maintain activities of daily living; and (iii) therapeutic effect. The nurses identified factors, such as: (i) therapeutic effect, (ii) issues associated with compliance, (iii) strategies to optimize compliance, (iv) familiarity with device, (v) triggers for changing oxygen therapy devices, as being key to the effective management of oxygen therapy.
Conclusion. Differences between the patients' and nurses' perspective of oxygen therapy illustrate the variety of factors that impact on effective oxygen administration. Further research should seek to provide a further in-depth understanding of the current oxygen administration practices of nurses and the patient factors that enhance or hinder effectiveness of oxygen therapy. Detailed information about nurse and patient factors that influence oxygen therapy will inform a sound evidence base for nurses' oxygen administration decisions.

Processes for disciplining nurses for unprofessional conduct of a serious nature : a critique

Aims: This paper critiques the deliberative processes used by the discipline panels of an Australian statutory nurse regulating authority when appraising the alleged unprofessional conduct of nurses and determining appropriate remedies.

Background: Little is known about the nature and effectiveness of the deliberative processes used by nurse regulating authorities (NRAs) disciplinary panels established to appraise and make determinations in response to allegations of unprofessional conduct by nurses.

Methods: A qualitative exploratory descriptive/pragmatic research approach was used. Data were obtained from two case-orientated sampling units: (1) 84 Reasons for Determination made between 1994 and 2000 and (2) a purposeful sample of 12 former and current nurse regulating authority members, nurse regulating authority staff and a nurse regulating authority representative who had experience of disciplinary proceedings and/or who had served on a formal hearing panel. Data were analysed using content and thematic analysis strategies.

Results: Attitudinal considerations (e.g. whether a nurse understood the 'wrongness' of his or her conduct; accepted responsibility for his or her conduct; exhibited contrition/shame during the hearing; was candid in his or her demeanour) emerged as the singularly most significant factor influencing discipline panel determinations. Disciplinary action is taken appropriately against nurses who have committed acts of deliberate malfeasance. NRAs may not, however, be dealing appropriately with nurses when disciplining them for making honest mistakes/genuine practice errors.

Conclusion: Traditional processes used for appraising and disciplining nurses who have made honest mistakes in the course of their work need to be substantially modified as they are at odds with the models of human error management that are currently being advocated and adopted globally to improve patient safety and quality of care in health care domains.

Clinical risk management and patient safety education for nurses : a critique

Nurses have a pivotal role to play in clinical risk management (CRM) and promoting patient safety in health care domains. Accordingly, nurses need to be prepared educationally to manage clinical risk effectively when delivering patient care. Just what form the CRM and safety education of nurses should take, however, remains an open question. A recent search of the literature has revealed a surprising lack of evidence substantiating models of effective CRM and safety education for nurses. In this paper, a critical discussion is advanced on the question of CRM and safety education for nurses and the need for nurse education in this area to be reviewed and systematically researched as a strategic priority, nationally and internationally. It is a key contention of this paper that without ‘good’ safety education research it will not be possible to ensure that the educational programs that are being offered to nurses in this area are evidence-based and designed in a manner that will enable nurses to develop the capabilities they need to respond effectively to the multifaceted and complex demands that are inherent in their ethical and professional responsibilities to promote and protect patient safety and quality care in health care domains.

Critical care nurses' haemodynamic decision making

For cardiac surgical patients, the immediate 2-hour recovery period is distinguished by potentially life-threatening haemodynamic instability. To ensure optimum patient outcomes, nurses of varying levels of experience must make rapid and accurate decisions in response to episodes of haemodynamic instability. Decision complexity, nurses’ characteristics, and environmental characteristics, have each been found to influence nurses' decision making in some form. However, the effect of the interplay between these influences on decision outcomes has not been investigated. The aim of the research reported in this thesis was to explore variability in critical care nurses' haemodynamic decision making as a function of interplay between haemodynamic decision complexity, nurses' experience, and specific environmental characteristics by applying a naturalistic decision making design. Thirty-eight nurses were observed recovering patients in the immediate 2-hour period after cardiac surgery. A follow-up semi-structured interview was conducted. A naturalistic decision making approach was used. An organising framework for the goals of therapy related to maintaining haemodynamic stability after cardiac surgery was developed to assist the observation and analysis of practice. The three goals of therapy were the optimisation of cardiovascular performance, the promotion of haemostasia, and the reestablishment of normothermia. The research was conducted in two phases. Phase One explored issues related to observation as method, and identified emergent themes. Phase Two incorporated findings of Phase 1, investigating the variability in nurses' haemodynamic decision making in relation to the three goals of therapy. The findings showed that patients had a high acuity after cardiac surgery and suffered numerous episodes of haemodynamic instability during the immediate 2-hour recovery period. The quality of nurses' decision making in relation to the three goals of therapy was influenced by the experience of the nurse and social interactions with colleagues. Experienced nurses demonstrated decision making that reflected the ability to recognise subtle changes in haemodynamic cues, integrate complex combinations of cues, and respond rapidly to instability. The quality of inexperienced nurses' decision making varied according to the level and form of decision support as well as the complexity of the task. When assistance was provided by nursing colleagues during the reception and recovery of patients, the characteristics of team decision making were observed. Team decision making in this context was categorised as either integrated or non integrated. Team decision making influenced nurses' emotions and actions and decision making practices. Findings revealed nurses' experience affected interactions with other team members and their perceptions of assuming responsibility for complex patients. Interplay between decision complexity, nurses' experience, and the environment in which decisions were made influenced the quality of nurses' decision making and created an environment of team decision making, which, in turn, influenced nurses' emotional responses and practice outcomes. The observed variability in haemodynamic decision making has implications for nurse education, nursing practice, and system processes regarding patient allocation and clinical supervision.

Metamemory training for memory disorders in adults with a closed head injury

The purpose of the present study was to investigate the efficacy of a memory and metamemory training program on memory performance and metamemory judgement accuracy in adults with a closed head injury. A multiple baseline across subjects design was used with six subjects. All subjects were seen at least two years post-injury. Training included general metamemory information about the nature of memory, use of a specific memory strategy to assist verbal recall (to Preview, Question, Read, State and Test- PQRST), specific metamemory information about the strategy, and a self instruction procedure (WTSC- What is the task, Select a strategy to use, Try out strategy, Check to evaluate strategy effectiveness). During the training period all subjects recalled greater than fifty percent of paragraph ideas while using PQRST. Follow-up tests showed that five of the six subjects maintained recall levels but a gradual decrease in slope was observed over eight weeks post-training. Tests of recall, recognition and metamemory judgements on Sentence and Action Tasks were used to evaluate generalisation of training. Two subjects showed improved recall and two subjects showed improved recognition performance. In addition, four subjects demonstrated greater metamemory judgement accuracy about recognition performance following training. Improved performance post-training was also observed for three subjects on the Rivermead Behavioral Memory Test and the Logical Memory subtest of the Wechsler Memory Scale-Revised, greater than that expected for repeated testing. Several factors were identified as having a role in subjects’ ability to benefit from training.

Nursing work and nursing knowledge : exploring the work of women's health nurses, patterns of power and praxis

The majority of women's health nurses in this study work in generalist community health centres. They have developed their praxis within the philosophy and policies of the broader women's health movement and primary health care principles in Australia. The fundamental assumption underlying this study is that women's health nurses possess a unique body of knowledge and clinical wisdom that has not been previously documented and explored. The epistemological base from which these nurses' operate offers important insights into the substantive issues that create and continually shape the practice world of nurses and their clients. Whether this represents a (re)construction of the dominant forms of health care service delivery for women is examined in this study. The study specifically aims at exploring the practice issues and experience of women's health service provision by women's health nurses in the context of the provision of cervical cancer screening services. In mapping this particular group of nurses practice, it sets out to examine the professional and theoretical issues in contemporary nursing and women's health care. In critically analysing the powerful discourses that shape and reshape nursing work, the study raises the concern that previous analyses of pursing work tend to universalise the structural and social subordination of nurses and nursing knowledge. This universalism is most often based on examples of midwifery and nursing work in hospital settings, and subsequently, because of these conceptualisations, all of nursing is too often deemed as a dependent occupation, with little agency, and is analysed as always in relation to medicine, to hospitals, to other knowledge forms. Denoting certain discourses as dominant proposes a relationship of power and knowledge and the thesis argues that all work relations and practices in health are structured by certain power/knowledge relations. This analysis reveals that there IX are many competing and complimentary power/knowledge relations that structure nursing, but that nursing, and in particular women's health nurses, also challenge the power/knowledge relations around them. Through examining theories of power and knowledge the analysis, argues that theoretical eclecticism is necessary to address the complex and varied nature of nursing work. In particular it identifies that postmodern and radical feminist theorising provide the most appropriate framework to further analyse and interpret the work of women's health nurses. Fundamental to the position argued in this thesis is a feminist perspective. This position creates important theoretical and methodological links throughout the whole study. Feminist methodology was employed to guide the design, the collection and the analysis. Intrinsic to this process was the use of the 'voices' of women's health nurses as the basis for theorising. The 'voices' of these nurses are highlighted in the chapters as italicised bold script. A constant companion along the way in examining women's health nurses' work, was the reflexivity with feminist research processes, the theoretical discussions and their 'voices'. Capturing and analysing descriptive accounts of nursing praxis is seen in this thesis as providing a way to theorise about nursing work. This methodology is able to demonstrate the knowledge forms embedded in clinical nursing praxis. Three conceptual threads emerge throughout the discussions: one focuses on nursing praxis as a distinct process, with its own distinct epistemological base rather than in relation to 'other' knowledge forms; another describes the medical restriction and opposition as experienced by this group of nurses, but also of their resistance to medical opposition. The third theme apparent from the interviews, and which was conceptualised as beyond resistance, was the description of the alternative discourses evident in nursing work, and this focused on notions of being a professional and on autonomous nursing praxis. This study concludes that rather than accepting the totalising discourses about nursing there are examples within nursing of resistance—both ideologically and X in practice—to these dominant discourses. Women's health nurses represent an important model of women's health service delivery, an analysis of which can contribute to critically reflecting on the 'paradigm of oppression' cited in nursing and about nursing more generally. Reflecting on women's health service delivery also has relevance in today's policy environment, where structural shifts in Commonwealth/State funding arrangements in community based care, may undermine women's health programs. In summary this study identifies three important propositions for nursing: • nursing praxis can reconstruct traditional models of health care; • nursing praxis is powerful and able to 'resist' dominant discourses; and • nursing praxis can be transformative. Joining feminist perspectives and alternative analyses of power provides a pluralistic and emancipatory politics for viewing, describing and analysing 'other' nursing work. At the micro sites of power and knowledge relations—in the everyday practice worlds of nurses, of negotiation and renegotiation, of work on the margins and at the centre—women's health nurses' praxis operates as a positive, productive and reconstructive force in health care.

The story of fable : a narrative analysis of the experience of four registered nurses in their first year of practice

This research explores the transition from student to registered nurse from the perspective of the new graduate. This interpretive study uses narrative analysis as the methodology. Individual stories were collected and processed using the method of core story creation and emplotment (Emden 1998). Four newly registered nurses were invited to share stories related to how they were experiencing their role. Participants were encouraged to tell their stories in response to the open question 'what is it like to be a registered nurse?' In the final step of the analysis one honest and critical story has been crafted (Barone 1992) using a process termed emplotment thus disclosing the themes that allow the stories to be grasped together as a single story (Polkinghorne 1988, Emden 1998). The final story of 'Fable' gives insight into the ways in which newly registered nurses experience their role. Becoming a registered nurse is not easy however, Fable finds that nursing is more than just a job and describes many rewarding experiences. It is hoped that the outcomes of this research will be valuable to students, graduates, nurse academics and the profession of nursing generally by enhancing understandings of the relationship between the graduate and the actual employment experience.

Women clinical nurses' constructions of collegiality : an ethnomethodological study

This research is about a shared journey of being together. It involved thirteen women nurses (including myself) in a process approach to working with data collected through audio transcriptions of conversations during group get-togethers, field notes and journalling over twelve months. The project was conducted in a large acute care metropolitan hospital where the ward staff interests lie in a practice history of the medical specialty of gynaecology and women's health. Prior to commencement ethical approval was gained from both the University and hospital ethics committees. Accessing the group was complicated by the political climate of the hospital, possibly exaggerated further by the health politics across the state of Victoria, at a time of major upheaval characterised by regionalism, rationalisation and debt servicing. In order to ascertain women clinical nurses' constructions of collegiality I adopted an ethnomethodological approach informed by a critical feminist lens to enable the participants to engage in a process of openly ideological inquiry, in critiquing and transforming practice. I felt the choice of methodology had to be consistent with my own ideological position to enable me to be myself (as much as I could) during the project. I wanted to work with women to illuminate the ways in which dominant ideologies had come to be apprehended, inscribed, embodied and/or resisted in the everyday intersubjective realities of participants. The research itself became a site of resistance as the group became aware of how and in what ways their lives had become distorted, while at the same time it collaboratively transformed their individual and collective practice understandings, enabling them to see the self and other anew. Set against the background of dominant discourses on collegiality, women's understandings of collegiality have remained a submerged discourse. Revealed in this work are complex inter-relationships that might be described by some as collegial!, but for others relations amongst these women depict alternative meanings in a rich picture of the fabric of ward life. The participants understand these relations through a connectedness that has empathy as its starting point. In keeping with my commitment to engage with these women I endeavoured to remain faithful to the dialogical approach to this inquiry. Moreover I have brought the voices of the women to the foreground, peeling away the rhizomatic interconnections in and between understandings. What this has meant in terms of the thesis is that the work has become artificially distanced for the purposes of academic requirements. Nevertheless it speaks to the understandings the participants have of their relationships; of the various locations of the visible and invisible voices; of the many landscapes and images, genealogies, subjectivities and multiple selves that inform the selves with(in) others and being-in-relation. Throughout the journey meanings are revealed, revisited and reconstructed. Many nuances comprise the subtexts illuminating the depths of various moral locations underpinning the ways these women engage with one another in practice. The process of the research weaves through multiple positions, conveying the centrality of shared goals, multiple identities, resistances and differences which contribute to a holding environment, a location in which women value one another in their being-in-relation and in which they stand separately yet together.

Bridging the divide: a survey of nurses' opinions regarding barriers to, and facilitators of, research utilization in the practice setting

Background. Many researchers have explored the barriers to research uptake in order to overcome them and identify strategies to facilitate research utilization. However, the research–practice gap remains a persistent issue for the nursing profession.

Aims and objectives. The aim of this study was to gain an understanding of perceived influences on nurses' utilization of research, and explore what differences or commonalities exist between the findings of this research and those of studies that have been conducted in various countries during the past 10 years.

Design. Nurses were surveyed to elicit their opinions regarding barriers to, and facilitators of, research utilization. The instrument comprised a 29-item validated questionnaire, titled Barriers to Research Utilisation Scale (BARRIERS Scale), an eight-item scale of facilitators, provision for respondents to record additional barriers and/or facilitators and a series of demographic questions.

Method. The questionnaire was administered in 2001 to all nurses (n = 761) working at a major teaching hospital in Melbourne, Australia. A 45% response rate was achieved.

Results. Greatest barriers to research utilization reported included time constraints, lack of awareness of available research literature, insufficient authority to change practice, inadequate skills in critical appraisal and lack of support for implementation of research findings. Greatest facilitators to research utilization reported included availability of more time to review and implement research findings, availability of more relevant research and colleague support.

Conclusion. One of the most striking features of the findings of the present study is that perceptions of Australian nurses are remarkably consistent with reported perceptions of nurses in the US, UK and Northern Ireland during the past decade.

Relevance to clinical practice. If the use of research evidence in practice results in better outcomes for our patients, this behoves us, as a profession, to address issues surrounding support for implementation of research findings, authority to change practice, time constraints and ability to critically appraise research with conviction and a sense of urgency.

Nurses' perceived barriers to the implementation of a Fall Prevention Clinical Practice Guideline in Singapore hospitals

Background

Theories of behavior change indicate that an analysis of barriers to change is helpful when trying to influence professional practice. The aim of this study was to assess the perceived barriers to practice change by eliciting nurses' opinions with regard to barriers to, and facilitators of, implementation of a Fall Prevention clinical practice guideline in five acute care hospitals in Singapore.
Methods

Nurses were surveyed to identify their perceptions regarding barriers to implementation of clinical practice guidelines in their practice setting. The validated questionnaire, 'Barriers and facilitators assessment instrument', was administered to nurses (n = 1830) working in the medical, surgical, geriatric units, at five acute care hospitals in Singapore.
Results

An 80.2% response rate was achieved. The greatest barriers to implementation of clinical practice guidelines reported included: knowledge and motivation, availability of support staff, access to facilities, health status of patients, and, education of staff and patients.
Conclusion

Numerous barriers to the use of the Fall Prevention Clinical Practice Guideline have been identified. This study has laid the foundation for further research into implementation of clinical practice guidelines in Singapore by identifying barriers to change in acute care settings.

Collaborative care : the role of practice nurses

Background
Comorbid depression can occur with diabetes and heart disease. This article reports on a feasibility study focusing on additional roles for practice nurses in detecting and monitoring depression with other chronic diseases.
Method
A convenience sample of six practices in southeast Australia was identified. Practice nurses received training via a workshop, which included training in the use of the Patient Health Questionnaire, to detect depression.
Results
The 332 patients who participated in the project each received a comprehensive health summary to assist with self management. Depression was identified in 34% of patients in this convenience sample. After 18 months implementation, practice nurses were strongly in favour of continuing the model of care. General
practitioners gave highly favourable ratings for effectiveness and willingness to continue this model of care.
Discussion
Practice nurses can include depression monitoring alongside systematic care of diabetes and heart disease. A randomised trial is currently underway to compare the clinical outcomes of this model with usual care.

Agency-nursing work : perceptions and experiences of agency nurses

This paper explores agency-nursing work from the perspective of agency nurses to gain in-depth understanding of their clinical practice, their relationships with the employing agency, hospitals and permanent nurses, and their professional status. For this study, individual interviews were conducted with ten agency nurses who were registered with one of three nursing agencies in Melbourne, Australia. Five major themes emerged from interview data: orientation, allocation of agency nurses, reasons for doing agency-nursing work, experiences with hospital staff, and professionalism. The findings reveal that the primary reason for nurses engaging in agency-nursing work is for the flexibility it offers. While agency nurses described a commitment to professionalism, the findings emphasise the need to establish effective communication networks between agency nurses, nursing agencies and hospital institutions. Such communication between stakeholders is important to facilitate discussion of issues such as appropriate notification of shift availability, appropriate assignment of work and recognition of the agency nurse as a valuable member of the health care team. In particular, the findings highlight the importance of comprehensive orientation and education for agency nurses to shift the focus of their daily work from task completion to more comprehensive patient care.
