Background. Nurses in a graduate programme in Australia are those who are in the first year of clinical practice following completion of a 3-year undergraduate nursing degree. When working in an acute care setting, they need to make complex and ever-changing decisions about patients' medications in a clinical environment affected by multifaceted, contextual issues. It is important that comprehensive information about graduate nurses' decision-making processes and the contextual influences affecting these processes are obtained in order to prepare them to meet patients' needs.
Aim. The purpose of this paper is to report a study that sought to answer the following questions: What are the barriers that impede graduate nurses' clinical judgement in their medication management activities? How do contextual issues impact on graduate nurses' medication management activities? The decision-making models considered were: hypothetico-deductive reasoning, pattern recognition and intuition.
Methods. Twelve graduate nurses who were involved in direct patient care in medical and surgical wards of a metropolitan teaching hospital located in Melbourne, Australia participated in the study. Participant observations were conducted with the graduate nurses during a 2-hour period during the times when medications were being administered to patients. Graduate nurses were also interviewed to elicit further information about how they made decisions about patients' medications.
Results. The most common model used was hypothetico-deductive reasoning, followed by pattern recognition and then intuition. The study showed that graduate nurses had a good understanding of how physical assessment affected whether medications should be administered or not. When negotiating treatment options, graduate nurses readily consulted with more experienced nursing colleagues and doctors.
Study limitations. It is possible that graduate nurses demonstrated a raised awareness of managing patients' medications as a consequence of being observed.
Conclusions. The complexity of the clinical practice setting means that graduate nurses need to adapt rapidly to make sound and appropriate decisions about patient care.

Alternative health care delivery models such as HITH facilitate the care of patients requiring acute treatments in their own homes. There are over 570 Diagnostic Related Groups managed in HITH programs and many of these are known to have associated physical pain. The impact of the home environment on patients’ experience of pain or how pain is managed is poorly understood. The purpose of this presentation is to
present the background and preliminary findings of a study that aims to increase our understanding of the issues related to providing optimal pain management for acute care patients who are transferred to Hospital in the Home. This knowledge will enable the development of effective practice guidelines to improve patient outcomes. More specifically, the aims are:
• To identify whether patients are transferred to HITH in pain or develop
   significant pain while in the program
• To identify the frequency and intensity of pain experienced by patients in 3      HITH programs.
• To describe patients’ experience of pain in the home environment.
• To investigate whether patients receive adequate pain relief once                      transferred to HITH.
• To explore the strategies patients use to manage pain at home.

The study will be carried out over 12 months in three HITH units in Victoria: Box Hill Hospital, Alfred Hospital and Epworth Hospital. The design is a descriptive survey of patients’ experience of pain and pain management using a modified version of The American Pain Society’s Patient Outcome Questionnaire. 360 consecutive surgical patients transferred to HITH care in the three participating programs will be interviewed by telephone between 48 and 72 hours of admission to the program.

The findings of this study will identify issues in providing optimum pain management for patients receiving acute care in non-traditional treatment environments.

Background : The benefits of cardiac rehabilitation (CR) programs are well established. Despite these benefits their utilisation remains sub-optimal, with an average of 24% of eligible cardiac patients attending outpatient CR programs across Victoria.
Aims & rationale/Objectives : The objectives of this study were to (a) identify local barriers and enablers to the uptake of hospital-based CR programs, and (b) identify preferred alternatives for the delivery of CR.
Methods : Six hospital-based CR programs within the region agreed to participate in this study. A consecutive series of patients referred to the programs were surveyed by the CR coordinators to identify the local barriers and enablers influencing CR program attendance. In addition, focus groups with CR participants and health professionals were conducted at two hospitals in order to ascertain their views on current programs, suggestions for improvements and alternative methods of CR delivery.
Principal findings : Survey data was obtained from a total of 97 patients referred to the CR programs during the study period, 27 (28%) females and 70 (72%) males. Main reasons given for CR non-attendance were related to distance to travel, cost of petrol, reliance on others for transport and lack of interest or motivation to attend. For CR attenders, main enablers included encouragement by family, medical and other health professionals, and having someone else to drive them. Suggestions for alternative methods of CR delivery included more programs in outlying communities, home and GP based programs, telephone support and a patient manual or workbook.
Discussion : The results of this study provide valuable information for designing strategies to increase utilisation of existing CR programs as well as pilot testing alternative modes of CR program delivery for cardiac patients in rural areas unable to access hospital-based CR.
Implications : These findings suggest that many of the barriers identified could be addressed by a more creative use of existing resources and the provision of CR services in primary care settings.

Objectives: The current study was designed to evaluate the knowledge, skills and self-efficacy of care providers from the perspective of professionals working in the aged-care industry.

Method: Participants were 21 professional carers, 10 General Practitioners and 7 aged-care managers. Focus groups, which involved the completion of a semi-structured interview related to knowledge, recognition, confidence, referral procedures and use of screening tools for the detection of depression, were conducted.

Results:
The results showed that all groups of respondents recognised significant gap in the knowledge and awareness of depression among professional care staff working with older people in both the community and residential care-settings. Skills in the detection and monitoring of depression and the self-efficacy of these care staff were also seen to be a problem.

Discussion:
The implications of these findings in terms of training programmes for professional carers working in the aged health care sector are discussed.

Nursing handover is a common part of nursing practice that is fundamental to safe patient care. Despite this, the literature provides little direction on the best way to conduct handover. This project aimed to examine nurses' perceptions of handover and to determine the strengths and limitations of the handover process. A staff survey was distributed to nurses in all inpatient wards at a metropolitan tertiary hospital. A total of 176 nurses responded to the staff survey. The findings revealed conflicting opinions about the effectiveness of the handover process; although a number of nurses were positive about current handover practice, indicating they were provided with sufficient information about patients and given opportunity to clarify patient care information, other nurses identified aspects of handover that could be improved. These included: the subjectivity of handover information, the time taken to conduct handover, repetition of information that could be found in the patients' care plans, and handing over of information by a nurse who has not cared for the patient. Some attention needs to given to addressing the perceived weaknesses associated with the handover process.

Aims and objectives. To explore nurses' understandings and expectations of rehabilitation and nurses' perceptions of patients' understandings and expectations of rehabilitation.
Background.
Within the context of a broadening appreciation of the benefits of rehabilitation, interest in the nature of rehabilitation is growing. Some believe that rehabilitation services do not adequately meet the needs of patients. Others are interested in the readiness of patients to participate in rehabilitation.
Design. Qualitative.
Method.
Grounded theory using data collected during interviews with nurses in five inpatient rehabilitation units and during observation of the nurses' everyday practice.
Findings. According to nurses working in inpatient rehabilitation units, there is a marked incongruence between nurses' understandings and expectations of rehabilitation and what they perceive patients to understand and expect.
Conclusion. Given these different understandings, an important nursing role is the education of patients about the nature of rehabilitation and how to optimise their rehabilitation.

Relevance to clinical practice.
Before patients are transferred to rehabilitation, the purpose and nature of rehabilitation, in particular the roles of patients and nurses, needs to be explained to them. The understandings of rehabilitation that nurses in this study possessed provide a framework for the design of education materials and orientation programmes that inform patients (and their families) about rehabilitation. In addition, reinforcement of the differences between acute care and rehabilitation will assist patients new to rehabilitation to understand the central role that they themselves can play in their recovery.

Background: Mental illness is an escalating concern worldwide. The management of disorders such as anxiety and depression largely falls to family doctors or general practitioners (GPs). However, GPs are often too time constrained and may lack the necessary training to adequately manage the needs of such patients. Evidence-based Internet interventions represent a potentially valuable resource to reduce the burden of care and the cost of managing mental health disorders within primary care settings and, at the same time, improve patient outcomes.
Objective: The present study sought to extend the efficacy of a therapist-assisted Internet treatment program for panic disorder, Panic Online, by determining whether comparable outcomes could be achieved and maintained when Panic Online was supported by either GPs or psychologists.
Methods: Via a natural groups design, 96 people with a primary diagnosis of panic disorder (with or without agoraphobia) completed the Panic Online program over 12 weeks with the therapeutic assistance of their GP (n = 53), who had received specialist training in cognitive behavioral therapy, or a clinical psychologist (n = 43). Participants completed a clinical diagnostic telephone interview, conducted by a psychologist, and a set of online questionnaires to assess panic-related symptoms at three time periods (pretreatment, posttreatment, and 6 month follow-up).
Results: Both treatments led to clinically significant improvements on measures of panic and panic-related symptomatology from pretreatment to posttreatment. Both groups were shown to significantly improve over time. Improvements for both groups were maintained at follow-up; however, the groups did differ significantly on two quality of life domains: physical (F1,82 = 9.13, P = .00) and environmental (F1,82 = 4.41, P = .04). The attrition rate was significantly higher among those being treated by their GP (χ21 = 4.40, P = .02, N = 96).
Conclusions: This study provides evidence that Internet-based interventions are an effective adjunct to existing mental health care systems. Consequently, this may facilitate and enhance the delivery of evidence-based mental health treatments to increasingly large segments of the population via primary care systems and through suitably trained health professionals.

Background: Time pressure and, occasionally, suboptimal assessment decisions are features of nursing in acute care.

Objectives: To explore the effect of generic and specialist clinical experience on the ability to detect the need to take action in acute care and the impact of time pressure on nurses' decision-making performance.

Methods: Experienced acute care registered nurses (n = 241) were presented with 50 vignettes of real clinical risk assessments. Each vignette contained seven information cues. In response to these vignettes, nurses had to decide whether to intervene or not. The 26 vignettes were time limited and mixed randomly into the 50 cases. Signal detection analysis was used to establish nurses' performance, personal decision thresholds ([beta]), and their abilities (d') to distinguish a signal of clinical risk from the clinical noise of noncontributory information.

Results: Nurses had significantly lower d' and were significantly less likely to indicate intervening under time pressure. For ability-but not threshold-there was a significant interaction of time pressure and years of experience in acute care. With no time pressure, d' increased in line with years of experience. Under time pressure, there was no effect.

Discussion: Time pressure reduced nurses' ability to detect the need and the tendency to report intervening. Thus, there were more failures to report appropriate intervention under time pressure, and the positive effects of clinical experience were negated under time pressure. More and larger scale research on the effect on clinical outcomes of time pressured nursing choices is required.

Objective: To determine whether nutrition interventions widen dietary inequalities across socioeconomic status groups.

Design: Systematic review of interventions that aim to promote healthy eating.

Data sources: CINAHL and MEDLINE were searched between 1990 and 2007.

Review methods: Studies were included if they were randomised controlled trials or concurrent controlled trials of interventions to promote healthy eating delivered at a group level to low socioeconomic status groups or studies where it was possible to disaggregate data by socioeconomic status.

Results: Six studies met the inclusion criteria. Four were set in educational setting (three elementary schools, one vocational training). The first found greater increases in fruit and vegetable consumption in children from high-income families after 1 year (mean difference 2.4 portions per day, p<0.0001) than in children in low-income families (mean difference 1.3 portions per day, p<0.0003). The second did not report effect sizes but reported the nutrition intervention to be less effective in disadvantaged areas (p<0.01). The third found that 24-h fruit juice and vegetable consumption increased more in children born outside the Netherlands ("non-native") after a nutrition intervention (beta coefficient = 1.30, p<0.01) than in "native" children (beta coefficient = 0.24, p<0.05). The vocational training study found that the group with better educated participants achieved 34% of dietary goals compared with the group who had more non-US born and non-English speakers, which achieved 60% of dietary goals. Two studies were conducted in primary care settings. The first found that, as a result of the intervention, the difference in consumption of added fat between the intervention and the control group was –8.9 g/day for blacks and –12.0 g/day for whites (p<0.05). In the second study, there was greater attrition among the ethnic minority participants than among the white participants (p<0.04).

Conclusions: Nutrition interventions have differential effects by socioeconomic status, although in this review we found only limited evidence that nutrition interventions widen dietary inequalities. Due to small numbers of included studies, the possibility that nutrition interventions widen inequalities cannot be excluded. This needs to be considered when formulating public health policy.

Aims. To explore and explain nurses' use of readily available clinical information when deciding whether a patient is at risk of a critical event.

Background. Half of inpatients who suffer a cardiac arrest have documented but unacted upon clinical signs of deterioration in the 24 hours prior to the event. Nurses appear to be both misinterpreting and mismanaging the nursing-knowledge 'basics' such as heart rate, respiratory rate and oxygenation. Whilst many medical interventions originate from nurses, up to 26% of nurses' responses to abnormal signs result in delays of between one and three hours.

Methods. A double system judgement analysis using Brunswik's lens model of cognition was undertaken with 245 Dutch, UK, Canadian and Australian acute care nurses. Nurses were asked to judge the likelihood of a critical event, 'at-risk' status, and whether they would intervene in response to 50 computer-presented clinical scenarios in which data on heart rate, systolic blood pressure, urine output, oxygen saturation, conscious level and oxygenation support were varied. Nurses were also presented with a protocol recommendation and also placed under time pressure for some of the scenarios. The ecological criterion was the predicted level of risk from the Modified Early Warning Score assessments of 232 UK acute care inpatients.

Results. Despite receiving identical information, nurses varied considerably in their risk assessments. The differences can be partly explained by variability in weightings given to information. Time and protocol recommendations were given more weighting than clinical information for key dichotomous choices such as classifying a patient as 'at risk' and deciding to intervene. Nurses' weighting of cues did not mirror the same information's contribution to risk in real patients. Nurses synthesized information in non-linear ways that contributed little to decisional accuracy. The low-moderate achievement (Ra) statistics suggests that nurses' assessments of risk were largely inaccurate; these assessments were applied consistently among 'patients' (scenarios). Critical care experience was statistically associated with estimates of risk, but not with the decision to intervene.

Conclusion. Nurses overestimated the risk and the need to intervene in simulated paper patients at risk of a critical event. This average response masked considerable variation in risk predictions, the need for action and the weighting afforded to the information they had available to them. Nurses did not make use of the linear reasoning required for accurate risk predictions in this task. They also failed to employ any unique knowledge that could be shown to make them more accurate. The influence of time pressure and protocol recommendations depended on the kind of judgement faced suggesting then that knowing more about the types of decisions nurses face may influence information use.

Relevance to clinical practice. Practice developers and educators need to pay attention to the quality of nurses' clinical experience as well as the quantity when developing judgement expertise in nurses. Intuitive unaided decision making in the assessment of risk may not be as accurate as supported decision making. Practice developers and educators should consider teaching nurses normative rules for revising probabilities (even subjective ones) such as Bayes' rule for diagnostic or assessment judgements and also that linear ways of thinking, in which decision support may help, may be useful for many choices that nurses face. Nursing needs to separate the rhetoric of 'holism' and 'expertise' from the science of predictive validity, accuracy and competence in judgement and decision making.

‘Health literacy’ refers to accessing, understanding and using information to make health decisions. However, despite its introduction into the World Health Organization's Health Promotion Glossary, the term remains a confusing concept. We consider various definitions and measurements of health literacy in the international and Australian literature, and discuss the distinction between the broader concept of ‘health literacy’ (applicable to everyday life) and ‘medical literacy’ (related to individuals as patients within health care settings). We highlight the importance of health literacy in relation to the health promotion and preventive health agenda. Because health literacy involves knowledge, motivation and activation, it is a complex thing to measure and to influence. The development of health literacy policies will be facilitated by better evidence on the extent, patterns and impact of low health literacy, and what might be involved in improving it. However, the current lack of consensus of definitions and measurement of health literacy will first need to be overcome.

Pressure ulcers are serious problems within hospital and aged care settings and are associated with adverse health outcomes and high treatment costs. Because of a high incidence of pressure ulcers in the health system, attention is now being directed to not just preventing, but also more effectively treating them. Nutrition plays a fundamental part in wound healing, with malnutrition, dehydration and recent weight loss identified as independent risk factors for the development of pressure ulcers. While the optimal nutrient intake to promote wound healing is unknown, increased needs for energy, protein, zinc and vitamins A, C and E have been documented. There is reasonable evidence to show that nutritional support, mostly by high-protein oral nutritional supplements, is effective in significantly reducing the incidence of pressure ulcers in at-risk patients by 25%. Intervention studies using high-protein or specialised disease-specific nutritional supplements support a trend to increased healing of established pressure ulcers. Such specialised supplements are typically based on defined amounts of arginine, vitamin C and zinc. Mechanisms by which nutritional support can aid in pressure ulcer prevention and healing are likely related to addressing macro- and/or micro-nutrient deficiencies arising from either poor oral intake or increased nutrient requirements related to the wound healing process. With much more research still to be done in this area, nutrition support appears an efficacious and costeffective adjunct to current medical and nursing approaches in the prevention and treatment of pressure ulcers.

Background: By providing information on the relative merits and potential harms of the options available and a framework to clarify preferences, decision aids can improve knowledge and realistic expectations and decrease decisional conflict in individuals facing decisions between alternative forms of action. Decision-making about prenatal testing for fetal abnormalities is often confusing and difficult for women and the effectiveness of decision aids in this field has not been established. This study aims to test whether a decision aid for prenatal testing of fetal abnormalities, when compared to a pamphlet, improves women's informed decision-making and decreases decisional conflict.

Methods/design: A cluster designed randomised controlled trial is being conducted in Victoria, Australia. Fifty General Practitioners (GPs) have been randomised to one of two arms: providing women with either a decision aid or a pamphlet. The two primary outcomes will be measured by comparing the difference in percentages of women identified as making an informed choice and the difference in mean decisional conflict scores between the two groups. Data will be collected from women using questionnaires at 14 weeks and 24 weeks gestation.

The sample size of 159 women in both arms of the trial has been calculated to detect a difference of 18% (50 to 68%) in informed choice between the two groups. The required numbers have been adjusted to accommodate the cluster design, miscarriage and participant lost – to – follow up.

Baseline characteristics of women will be summarised for both arms of the trial. Similarly, characteristics of GPs will be compared between arms.

Differences in the primary outcomes will be analysed using 'intention-to-treat' principles. Appropriate regression techniques will adjust for the effects of clustering and include covariates to adjust for the stratifying variable and major potential confounding factors.

Discussion: The findings from this trial will make a significant contribution to improving women's experience of prenatal testing and will have application to a variety of maternity care settings. The evaluation of a tailored decision aid will also have implications for pregnancy care providers by identifying whether or not such a resource will support their role in providing prenatal testing information.

Definitions of family and disclosure of family configuration are important themes for understanding the experiences of contemporary lesbian-parented families. Drawing on multi-generational family interviews with 20 lesbian-parented families in Victoria, Australia, we explore how participants describe and present their families in public contexts. We found a marked difference in experience between lesbian-parented stepfamilies and lesbian-parented de novo families where children are conceived and raised by lesbian parents from birth. Family members adopted a variety of strategies when disclosing parents’ sexual orientation in mainstream social institutions such as health care settings and schools. Some chose a proud, open strategy; while others were more private; yet others chose a passive strategy, particularly when dealing with health care providers, and a selective strategy when dealing with schools. These strategies demonstrate
the fine balance that families must strike between being publicly authentic and creating safety by protecting themselves from negative attitudes.

There is growing awareness of the benefits of rehabilitation both in Australia and overseas. While the provision of rehabilitation services is not new, recognition of this type of health service as an integral part of health care has been linked to changes in the provision of acute care services, advances in medical technology, improvements in the management of trauma and an ageing population. Despite this, little attention has been paid to nursing's contribution to patient rehabilitation in Australia. The aim of this grounded theory study, therefore, was to collect and analyse nurses' reports of their contributions to patient rehabilitation and to describe and analyse contextual factors influencing that contribution. Data were collected during interviews with registered and enrolled nurses working in five inpatient rehabilitation units in New South Wales and during observation of the nurses' everyday practice. A total of 53 nurses participated in the study, 35 registered nurses and 18 enrolled nurses. Grounded theory, informed by the theoretical perspective of symbolic interactionism, was used to guide data analysis, the ongoing collection of data and the generation of a substantive theory. The findings revealed six major categories. One was an everyday problem labelled incongruence between nurses' and patients' understandings and expectations of rehabilitation. Another category, labelled coaching patients to self-care, described how nurses independently negotiated the everyday problem of incongruence. The remaining four categories captured conditions in the inpatient context which influenced how nurses could contribute to patient rehabilitation. Two categories, labelled segregation: divided and dividing work practices between nursing and allied health and role ambiguity, were powerful in shaping nursing's contribution as they acted individually and synergistically to constrain nursing's contribution to patient rehabilitation. The other two categories, labelled distancing to manage systemic constraints and grasping the nettle to realise nursing's potential, represent the mutually exclusive strategies nurses used in response to segregation and role ambiguity. From exploration of the relationship between the six categories, the core category and an interactive grounded theory called opting in and opting out emerged. In turn, this grounded theory reveals nursing's contribution to inpatient rehabilitation as well as contextual conditions constraining that contribution. The significance of these findings is made manifest through their contribution to the advancement of nursing knowledge and through implications for nursing practice and education, rehabilitation service delivery and research.
