Relationship between alcohol abuse upper gastro-intestinal haemorrhage and nutritional status during acute hospital admission

This thesis is concerned with the effect of alcohol consumption on the pathogenesis of bleeding from the upper gastrointestinal tract via nutritional pathways. Altered nutritional status is a frequently recognised clinical accompaniement of heavy alcohol consumption in hospitalized patients. Similarly, upper gastrointestinal bleeding is frequently accompanied by the presence of heavy alcohol consumption. Nevertheless, the clinical quantification of alcohol intake is often descriptive, so that a link between alcohol use and upper gastrointestinal haemorrhage via nutritional mechanisms has been only generally defined. In the literature review, the methods of defining alcohol use and abuse, using interview, biochemical and haematological techniques are noted. The relationship between alcohol abuse and nutrient imbalances is reviewed, especially in relation to possible effects on the gastrointestinal tract, appetite and eating habits. A further section reviews the relationship between alcohol use and anatomical lesions of the upper gastrointestinal tract likely to lead to bleeding. Following the chapter in which the methods used in this thesis are described. Chapter 4 seeks to describe the study population and its subgroups in this thesis in relation to interview, biochemical and haematological methods. Alcohol use is defined in relation to (1) a clinical classification of heavy or light drinking, based on a questionnaire administered in Casualty, (2) a quantified method of determining alcohol consumption during a subsequent ward dietetic assessment, (3) in relation to a biochemical definition (recent drinking and non-drinking), and a classification of (1) and (2) called, for the purposes of this thesis, 'alcohol abusers' and 'nonabusers'. Heavy, regular and recent drinkers and alcohol abusers tend to be male and younger than light, infrequent and nonrecent drinkers and nonabusers. Chapter 5 relates the nutritional status of those patients admitted acutely to hospital in relation to the groups defined in Chapter 4, Nutritional status is defined in terms of food intake, anthropometry, biochemical and haematological parameters. Different methods of defining alcohol use give rise to different patterns of nutritional impairment. Chapter 6 relates the nutritional status of those patients admitted acutely to hospital in relation to the presence or absence of an endoscopically defined site of upper gastrointestinal bleeding. A difference is seen between those bleeding from a Mailory-weiss tear and other sites of bleeding, similarly, biochemical differences in nutritional status emerge between those patients who presented in shock, and those who did not. Chapter 7 explores the relationships between biochemical markers of nutritional status and haemostatic variables in the groups of abusers/non-abusers, the various sites of primary bleeding/controls, and shock/non-shock. Serum copper appears to be related to altered haemostasis in a manner not apparently described elsewhere.

Geelong community's priorities and expectations of public health care

Abstract This thesis set out to achieve the following objectives: (1) To identify the priorities and expectations that the Geelong community has of its public health care system. (2) To determine if there is a common view on the attributes of a just health system. (3) To consider a method of utilising the data in the determination of health care priority setting in Barwon Health. (4) To determine a model of community participation which enables ongoing input into the decision making processes of Barwon Health. The methodology involved a combination of qualitative and quantitative research. The qualitative work involved the use of focus groups that were conducted with 64 members of the Geelong community. The issues raised informed the development of the interview schedule that was the basis of the quantitative study, which surveyed a representative sample of 400 members of the Geelong community. Prior to reporting on this work, the areas of distributive justice, scarcity and community participation in health care were considered. The research found that timely access to public hospitals, emergency care and aged care services were the major priorities; for many people, the cost was less relevant than a quality service. Shorter waiting times and increased staffing levels were strongly supported. Increased taxes were nominated as the best means of financing the health system they sought. Community based services were less relevant than hospital services but health education was supported. An egalitarian approach to resource distribution was favoured although the community was prepared to discriminate in favour of younger people and against older people. There was strong support for the community to be involved in decision making in the public health care system through surveys or focus groups but very little support was given to priorities being determined by politicians, administrators and to a lesser extent, medical professionals.

Mothers' transition back to work and infants' transition to child care : does work-based child care make a difference?

The overall aim in this study was twofold: to compare the use of work-based (WB) and non-work-based (NWB) child care on the transition back to the workplace for women after a period of maternity leave, and on the transition into child care for the infants of these women. Thirty-five mothers with infants in WB centres and 44 mothers with infants in NWB centres completed a battery of questionnaires, retrospectively, in relation to their first four weeks of resuming work and their infant’s transition into child care. We first explored whether the mothers of infants in WB centres were less stressed and anxious
about separating from their infant, were more satisfied with their child care, and whether they felt more productive and supported at work than mothers of infants in NWB child
care centres. Our findings revealed no differences between mothers using WB centres and NWB centres in their transition to work. In exploring whether infants placed in WB centres settled faster and more easily than infants placed in NWB centres, the findings, once again, revealed no differences in the infant’s affective states at child care and maintenance of their routines, such that all infants were equally settled and happy irrespective of the type of care used. The theoretical and practical implications of our findings are discussed.

Lesbian and gay experiences of primary care in one borough in North London, UK

This paper reports the findings of a research study which explored the experiences of lesbians and gay men in relation to primary care services in general practice in a multiracial borough in North London, UK. The research took a qualitative approach and used several methods including a literature review, interviews with stakeholders (n = 6), focus group discussions (n = 27) and completion (n = 42) of a survey distributed to lesbians and gay men locally. The process facilitated the development of a grounded theory. The important themes to emerge were finding a GP and coming out, sexual health issues, mental health issues and communication with the GP. Given the high level of mobility among this population, there were problems in maintaining continuity of care, and a lack of protocols to facilitate the sharing of knowledge between patients and practitioners while reducing reliance on heterosexual assumptions. There were clear differences between the treatment of women and men in relation to sexual health, and neither approach could be said to be patient centred or inclusive of diversity of need. The fact that many informants accessed alternative sources of healthcare indicated that they were concerned to promote and maintain their health and wellbeing in a holistic manner. The lack of transparent protocols within general practice inhibited some informants from being as open and honest about their sexuality with their GPs as they were with their families or their employers. The findings highlight (1) the need for organisational development within primary care to improve sensitivity to the needs of lesbians and gay men; (2) the value of research to engage with the social experiences of lesbians and gay men; (3) the importance of engaging with the differing experiences of lesbians and gay men in relation to sexual health concerns.

Use of restraint in residential care settings for children and young people

An international movement promoting the reduced use of physical restraint and other coercive practices has brought into focus the ways in which those who are responsible for the care of children and young people respond to problematic behaviour. The topic generates emotive discussion, with proponents advancing the argument that the use of coercive measures enhances the quality of care and protects young people from harm, and civil libertarians who argue that restraint is never an appropriate way of managing behaviour. Despite such debates there is an absence of good research and scholarly activity on restraint practices, leading to uncertainty about the immediate and long-term effects of particular practices on both staff and young people. Consequently, it has been difficult for agencies to develop clear, consistent, and definitive policies. Drawing on international perspectives, the aim of this article is to discuss issues relevant to the practice of restraint in residential care facilities for children and young people in Australia, highlighting a number of issues that require resolution prior to the development of practice guidelines.

A comparative analysis of directors' duty of care, skill and diligence in South Africa and in Australia

The South African and Australian law regarding directors' duty of care, ski ll and diligence were influenced considerably by English precedent of the late 1800s and early 19005. Originally both jurisdictions adopted a conservative approach towards directors' duty of care, skill and diligence. This resulted in very low standards of care, skill and diligence expected of directors. In Australia, the standards of care and diligence expected of directors changed drastically with the case of Daniels v Anderson, where objective standards were used to determine a breach of directors' duty of care and diligence, and when objective standards of care and diligence were introduced in Australian corporations legislation. In this article it is submitted that if the opportunity arose for a South African court to consider whether a director is in breach of his or her common law duty of care, skill and diligence, the form of fault that will be required will be negligence as judged against the standards of a reasonable person. This means that in actual fact objective standards of care and diligence are expected of directors in South Africa. Although section 76(3) of the South African Companies Act 71 of 2008 does not introduce purely objective standards of care, skill and diligence, the section is defended in this article. It is pointed out that encouraging emerging entrepreneurs to become directors of South African companies provides justification for keeping subjective elements as part of the test to determine whether a director was in breach of his or her statutory duty of care, skill and diligence.

Environmental mastery and depression in older adults in residential care

This study investigated the association between environmental mastery and depression in a sample of 96 older adults (aged 64–98 years) in residential care. The participants completed a scale that assessed depression along with measures for risk factors for depression such as functional capacity, self-evaluated physical health, bereavement experiences and environmental mastery. The results showed that 49 per cent of the variance in participants’ scores in depression could be attributed to their self-reported level of environmental mastery. Given the complexity of depression and the likelihood of reduced environmental mastery among older adults in residential care, the construct was further assessed as a mediating variable between the risk factors and depression. With environmental mastery taken as such, the explained variance in depression increased to 56 per cent. It was concluded that environmental mastery may be one of the more important factors affecting the mental health of older adults living in residential care and that strategies for increasing the residents’ environmental mastery are important to their psychological wellbeing. The discussion notes that among the questions needing further investigation are whether older adults who experience high environmental mastery make the transition from community living to residential nursing home care more successfully than others, and whether perceived mastery diminishes over time or occurs at the point of transition from community independent living to dependent supported living.

Communication at the bedside to enhance patient care : a survey of nurses’ experience and perspective of handover

Strategies to support continuity of care and improve patient safety during clinical handover have been developed. The aims of this study were to identify the strengths and limitations in current practice of nursing clinical handover and implement a new bedside handover process. A total of 259 nurses completed a cross-sectional survey at change of shift on 1 day, which was followed by an audit of the pilot implementation of bedside handover. The survey results showed great variation in the duration, location and method of handover with significant differences in the experience of nurses employed part-time compared with full-time. Following implementation of standardized bedside handover on two wards, the audit revealed significant improvement in the involvement of patients, use of Situation-Background-Assessment-Recommendation, active patient checks and checking of documentation. These findings suggest the use of standardized protocols and communication tools for bedside handover improve continuity of patient care

MAAGs: the next generation. A study of the development of medical audit advisory groups and the arrangements for supporting clinical audit in primary care

Background: MAAGs have, historically, been disparate organisations with a lack of central direction, albeit with the same goal: to develop and support the performance of audit in primary care. This goal has been (and is being) achieved in a number of ways all over the country. In the last two years, MAAGs have witnessed many changes in primary care and are adapting themselves to suit these new arrangements at a local level.

Aim: To formalise our knowledge of where MAAGs are going, how they are getting there and the support they are receiving.

Method: A postal questionnaire to the 104 MAAGs in England and Wales, addressing 6 main issues of relevance to the development of MAAGs and the support they are receiving.

Results: At least two MAAGs have dissolved, leaving a possible total of 102 still in existence. Of these, 76 (74.5%) responded to the survey. The composition of the MAAG committee has changed dramatically since the inception of MAAGs in 1990, and staffing levels appear to have risen substantially. MAAGs appear to be more adequately funded by their health authorities than has previously been reported and many are actively seeking additional sources of funding. There is still large variation in levels of MAAG funding. Furthermore, funding is unrelated to the number of GPs or practices served. Security for MAAG staff appears to have been addressed in many areas, with 84% of MAAGs having at least one member of staff on a permanent employment contract. Many MAAGs are developing rolling programmes in an attempt to eliminate the short-sighted approach to the development of clinical audit that has existed since MAAGs were first set up.

Conclusion: Many MAAGs (with the obvious exception of those that have been dissolved) appear to be thriving without central direction or initiative. It is now evident that we were a little hasty in our concerns for the future of MAAGs beyond April 1996. It would seem that many organisations have taken the situation which arose two years ago as an opportunity to grow and develop in ways that may not have been possible within the confines of the Health Circular.

Improving care for people with osteoarthritis of the hip and 'knee : how has national policy for osteoarthritis been translated into service models in Australia?

There is strong rationale for improving care for people with chronic conditions, including osteoarthritis (OA). Successful implementation of healthcare reform requires new concepts and directions that are strongly supported by policy, new models of care (service redesign) and changes in day-to-day practice (healthcare provider and patient practice). In this paper we discuss the extent to which policy about management of OA of the hip and knee has been translated into new service models in Australia. A structured search of government and other key health websites in Australia was performed to identify policy, funding initiatives and new services models for managing OA of the hip and knee. This search was supported by a literature review. Musculoskeletal conditions were designated a National Health Priority in Australia in 2002. Under the Better Arthritis and Osteoporosis Care initiative, Australia has developed a national policy for OA care and national evidence-based clinical practice guidelines for management of OA of the hip and knee. Only two well described examples of new chronic disease management service models, the Osteoarthritis Clinical Pathway (OACP) model and the Osteoarthritis Hip and Knee Service (OAHKS) were identified. Primarily focused within acute care public hospital settings, these have been shown to be feasible and acceptable but have limited data on clinical impact and cost-effectiveness. While policy is extant, implementation has not been systematic and comprehensive. Clinicians have evidence-based recommendations for OA management but are poorly supported by service models to deliver these effectively and efficiently.

Family-centred practice : empowerment, self-efficacy, and challenges for practitioners in early childhood education and care

Family-centred practice has been included in the Victoria, Australia Early Years Learning and Development Framework as a key practice principle for professionals working across all early years programs in that state. While this model of partnership for engaging and collaborating with families has long been used in the early intervention sector, the efficacy of adopting this model more widely across the wider early childhood education and care sector has not been explored. This article presents a discussion on family-centred practice as a model for engaging with families in the care and education of their children. Through an analysis of the underlying philosophy and an examination of the core principles and characteristics, the article explores family-centred practice as it sits within a broader theory of partnership. This analysis identifies that while there are essential principles and characteristics that position the model within a partnership framework, it is the notion of empowerment, an underpinning philosophy guiding the model, that adds another dimension to the way practitioners in early childhood education and care settings collaborate with families. In examining the broader early childhood context, the capacity of many early childhood practitioners to effectively implement empowering behaviours is challenged.

Bioethics, cultural differences and the problem of moral disagreements in end-Of-life care : a terror management theory

Cultural differences in end-of-life care and the moral disagreements these sometimes give rise to have been well documented. Even so, cultural considerations relevant to end-of-life care remain poorly understood, poorly guided, and poorly resourced in health care domains. Although there has been a strong emphasis in recent years on making policy commitments to patient-centred care and respecting patient choices, persons whose minority cultural worldviews do not fit with the worldviews supported by the conventional principles of western bioethics face a perpetual struggle in getting their care needs met in a meaningful, safe, and healing way. In this essay, attention is given to exploring why cultural differences exist, why they matter, and how health care providers should treat them in order to reduce the incidence and impact of otherwise preventable harmful moral outcomes in end-of-life care. In addressing these questions, a novel application of the renowned terror management theory will be made.

Non-face to face consultations and communications in primary care : the role and perspective of general practice managers in Scotland

Background Practice managers play an important role in the organisation and delivery of primary care, including uptake and implementation of technologies. Little is currently known about practice managers’ attitudes to the use of information and communication technologies, such as email or text messaging, to communicate or consult with patients.

Objectives To investigate practice managers’ attitudes to non-face-to-face consultation/communication technologies in the routine delivery of primary care and their role in the introduction and normalisation of these technologies.

Methods We carried out a mixed-methods study in Scotland, UK. We invited all practice managers in Scotland to take part in a postal questionnaire survey. A maximum variation sample of 20 survey respondents participated subsequently in in-depth qualitative interviews.

Results Practice managers supported the use of new technologies for routine tasks to manage workload and maximise convenience for patients, but a range of contextual factors such as practice list size, practice deprivation area and geographical location affected whether managers would pursue the introduction of these technologies in the immediate future. The most common objections were medico-legal concerns and lack of perceived patient demand.

Conclusion Practice managers are likely to play a central role in the introduction of new consultation/communication technologies within general practice. They hold varying views on the appropriateness of these technologies, influenced by a complex mix of contextual characteristics.Managers from areas in which the ethos of the practice prioritises personalised care in service delivery are less enthusiastic about the adoption of remote consultation/ communication technologies.

Implementation of a quality care management system for patients with arthritis of the hip and knee

The Orthopaedic Unit of the Repatriation General Hospital (RGH) in Adelaide, South Australia has implemented a quality care management system for patients with arthritis of the hip and knee. The system not only optimises conservative management but ensures that joint replacement surgery is undertaken in an appropriate and timely manner. This new service model addresses identified barriers to service access and provides a comprehensive, coordinated strategy for patient management. Over 4 years the model has reduced waiting times for initial outpatient assessment from 8 to 3 months and surgery from 18 to 8 months, while decreasing length of stay from 6.3 to 5.3 days for hips and 5.8 to 5.3 days for knees. The service reforms have been accompanied by positive feedback from patients and referring general practitioners in relation to the improved coordination of care and enhanced efficiency in service delivery.

What is known about the topic? Several important initiatives both overseas and within Australia have contributed significantly to the development of this model of care. These include the UK National Health Service ‘18 weeks’ Project, the Western Canada Waiting List Project, the New Zealand priority criteria project, the Queensland Health Orthopaedic Physiotherapy Screening Clinic, and most importantly the Melbourne Health–University of Melbourne Orthopaedic Waiting List Project where a wide range of models were explored across Victorian hospitals from 2005 and the Multi-Attribute Prioritisation Tool (MAPT) was developed, validated and tested. This project became the Osteoarthritis Hip and Knee Service (OAHKS) and was operationalised in the Victorian healthcare system from 2012. These initiatives examined and addressed various aspects of management systems for patients with arthritis of the hip and knee in their particular setting.

What does this paper add? The development of this system is an extension of what is already known and is the first to encompass a comprehensive and coordinated strategy across all stages of the care management pathway for this patient group. Their management extends from the initial referral to development and implementation of a management plan, including surgery if assessed as necessary and organisation of long-term post operative follow up as required. By detailing the elements, key processes and measurable outcomes of the service redesign this paper provides a model for other institutions to implement a similar initiative.

What are the implications for practitioners? An important aspect of the design process was practitioner acceptance and engagement and the ability to improve their capacity to deliver services within an efficient and effective model. Intrinsic to the model’s development was assessment of practitioner satisfaction. Data obtained including practitioner surveys indicated an increased level of both satisfaction with the redesigned management service, and confidence in it to deliver its intended improvements.

Nursing care practices following a percutaneous coronary intervention : results of a survey of Australian and New Zealand cardiovascular nurses

Background: Although there is high-level evidence to guide optimal medical care for percutaneous coronary interventions, there are less explicit guidelines to support nurses in providing care. Aim: This study describes the practice standards and priorities of care of cardiovascular nurses in Australia and New Zealand. Method: Item generation for the survey was informed by an integrative literature review and existing clinical guidelines. A 116-item Web-based survey was administered to cardiovascular nurses, via electronic mail lists of professional cardiovascular nursing organizations, using a secure online data collection system. Results: Data were collected from March 2008 to March 2009. A total of 148 respondents attempted the survey, with 110 (74.3%) completing all items. All respondents were registered nurses with an average of 12.3 (SD, 7.61) years of clinical experience in the cardiovascular setting. A range of practice patterns was evident in ambulation time after percutaneous coronary intervention, methods of sheath removal, pain relief, and patient positioning. Respondents consistently rated psychosocial care a lower priority than other tasks and also identified a knowledge deficit in this area. Conclusion: This survey identified diversity of practice patterns and a range of educational needs. Increasing evidence to support evidence-based practice and guideline development is necessary to promote high-quality care and improved patient outcomes.
