Addressing the burden of heart failure in Australia: the scope for home-based interventions

Efficacy of Eye Movement Desensitization and Reprocessing on the Quality of Life in Patients with Major Depressive Disorder: A Randomized Clinical Trial

Introduction

The present study was conducted with the aim of investigating the efficacy of eye movement desensitization and reprocessing (EMDR) on the quality of life (QOL) in patients with major depressive disorder (MDD).

Methods

This is a randomized clinical trial study that investigated the efficacy of EMDR on the QOL in patients with MDD. In this study, all patients suffered from psychological trauma were currently in a major depressive episode and had a history of depression. 70 patients with MDD were selected through convenience sampling. Patients were then assigned to two groups of intervention and control (35 patients in each group). The assignment was performed randomly. For the intervention group, EMDR were performed in eight 90 mins sessions over 3 weeks. For the control group, no intervention was considered. Data on the QOL were collected using the WHO Quality of Life-BREF instrument before and after the treatment, and analysed using descriptive tests, paired t-test, independent t-test, and chi-square with SPSS v19.

Results

This study showed that the QOL in all its domains (physical health, psychological health, social relationships and environments) was significantly improved in patients with MDD in the intervention group after 8 sessions of EMDR. The post-treatment effect for the EMDR condition was 2.11, with a confidence interval of 1.3 to 2.7. Another finding of this study was that there was a statistically significant difference in the QOL scores in patients in the control group before and after the treatment; however, the mean difference in the intervention group was more than the control.

Conclusion

The results of this study showed that EMDR were effective on the QOL in patients with major depressive disorder, and improved individuals' QOL and all its domains. Treatment team members may use this technique as an effective and supportive one to improve the QOL in patients.

Cost-Utility Analysis of Home-Based Telerehabilitation Compared With Centre-Based Rehabilitation in Patients With Heart Failure

BACKGROUND

Whilst home-based telerehabilitation has been shown non-inferior to traditional centre-based rehabilitation in patients with chronic heart failure, its economic sustainability remains unknown. This study aimed to investigate the cost-utility of a home-based telerehabilitation program.

METHODS

A comparative, trial-based, incremental cost-utility analysis was conducted from a health care provider's perspective. We collected data as part of a multi-centre, two-arm, non-inferiority, randomised controlled trial with 6 months follow-up. There were 53 participants randomised to either a telerehabilitation program (consisting of 12 weeks of group-based exercise and education delivered into the home via online videoconferencing) or a traditional centre-based program. Health care costs (including personnel, equipment and hospital readmissions due to heart failure) were extracted from health system records, and calculated in Australian dollars using 2013 as the base year. Health utilities were measured using the EuroQol five-dimensional (EQ-5D) questionnaire. Estimates were presented as means and 95% confidence intervals (CIs) based on bootstrapping. Costs and utility differences were plotted on a cost-effectiveness plane.

RESULTS

Total health care costs per participant were significantly lower in the telerehabilitation group (-$1,590, 95% CI: -2,822, -359) during the 6 months. No significant differences in quality-adjusted life years (0, 95% CI: -0.06, 0.05) were seen between the two groups.

CONCLUSIONS

Heart failure telerehabilitation appears to be less costly and as effective for the health care provider as traditional centre-based rehabilitation.

Australian women and heart disease: Trends, epidemiological perspectives and the need for a culturally competent research agenda

Heart disease commonly manifests as acute coronary syndromes (unstable angina pectoris, or myocardial infarction) and heart failure (HF). These conditions are major causes of morbidity and mortality in Australia and internationally. Australian faces particular challenges in health care delivery given the cultural and ethnic diversity of society and unique issues related to rurality. These factors have significant implications for health care delivery. Following an acute cardiac event women have poorer outcomes: higher mortality rates, higher incidence of complications and greater psychological morbidity compared with men. Language barriers, socioeconomic factors, psychological trauma related to migration and alternate health seeking behaviors and varying perceptions of risk are likely to impact adversely on health outcomes. Self-management in chronic cardiovascular disease underscores the importance of models of care that incorporate aspects related to self-care and promotion of adherence to primary and secondary prevention initiatives. Implicit in this statement is the inclusion of the individual in negotiating and developing their care plan. Therefore health professionals need to be aware of the patient's needs, values, beliefs and health seeking behaviours. These factors are strongly influenced by culture and ethnicity. The cultural diversity of Australian society mandates cultural competence in health care. This paper presents an overview of nursing science related to women and heart disease in Australia and suggests directions for culturally-competent research and development and evaluation of models of care to improve health outcomes for all Australians.

Outcomes and opportunities: a nurse-led model of chronic disease management in Australian general practice

The Australian government’s commitment to health service reform has placed general practice at the centre of its agenda to manage chronic disease. Concerns about the capacity of GPs to meet the growing chronic disease burden has stimulated the implementation and testing of new models of care that better utilise practice nurses (PN). This paper reports on a mixed-methods study nested within a larger study that trialled the feasibility and acceptability of a new model of nurse-led chronic disease management in three general practices. Patients over 18 years of age with type 2 diabetes, hypertension or stable ischaemic heart disease were randomised into PN-led or usual GP-led care. Primary outcomes were self-reported quality of life and perceptions of the model’s feasibility and acceptability from the perspective of patients and GPs. Over the 12-month study quality of life decreased but the trend between groups was not statistically different. Qualitative data indicate that the PN-led model was acceptable and feasible to GPs and patients. It is possible to extend the scope of PN care to lead the routine clinical management of patients’ stable chronic diseases. All GPs identified significant advantages to the model and elected to continue with the PN-led care after our study concluded.

Frequency of urinary incontinence in people with chronic heart failure

OBJECTIVES

The purpose of the study was to examine the frequency and severity of urinary incontinence in people with heart failure (HF). Secondary aims were to determine the differences in known risk factors for those who were continent and incontinent, to investigate the correlates of urinary incontinence in people with HF, and to examine the relationship between urinary incontinence with medication adherence, in particular, diuretics, and quality of life.

BACKGROUND

Urinary incontinence is a common condition affecting older adults. However, the frequency of incontinence in people with HF remains largely unknown.

METHODS

This was a descriptive study. A convenience sample of 181 people with HF were surveyed to determine frequency, severity and presence of risk factors of urinary incontinence and dosages of prescribed HF medications. Instruments included the Revised Urinary Incontinence Scale, Medication Adherence Report Scale and Incontinence Impact Questionnaire Short Form. Regression analyses were used to examine relationships between variables and presence of urinary incontinence.

RESULTS

Eighty-nine people responded (66% male, mean age 67 years), 44 (49%) self-reporting urinary incontinence. Of these, 30 (34%) respondents rated their incontinence severity as slight or moderate. More incontinent respondents took furosemide doses greater than 20 mg daily (P = 0.046) and low doses of beta-blockers compared with continent respondents (P = 0.002). Taking low doses of beta-blockers explained 23% of variance for urinary incontinence (r(2) = 0.23, P = 0.015). Incontinent respondents reported altering or missing a diuretic dose (P < 0.02) compared with those who were continent.

CONCLUSIONS

Frequency of urinary incontinence in this group of people with HF appears high. It appears that screening for urinary incontinence may be important as part of routine care in HF management programmes. In addition, awareness of dosages of furosemide and beta-blockers and in particular, adherence to diuretics also should be monitored. Prospective studies investigating these issues and the effect of targeted interventions are required.

Effectiveness of general practice nurse interventions in cardiac risk factor reduction among adults

Background  Cardiovascular disease is the leading cause of death for adults in Australia. In recent years there has been a shift in health service delivery from institutional to community-based care for chronic conditions, including cardiovascular disease. The general practice setting is seen to offer greater flexibility, higher levels of efficiency and more client focused healthcare delivery than is possible in the acute care sector. It has been suggested that practice nurses represent a useful adjunct to current models of cardiovascular disease management. To date, significant descriptive research has been conducted exploring the demographics, roles, educational needs and issues facing practice nurses. However, there is a need to evaluate the effectiveness of practice nurse interventions in terms of patient outcomes, clinician satisfaction and cost-effectiveness. Objectives  This review seeks to present the best available evidence regarding the efficacy of general practice nurse interventions for cardiac risk factor reduction in healthy adults, as well as those with established cardiovascular disease or known cardiac risk factors. Search Strategy  A systematic literature search was performed using Medline (1966 - 2005), CINAHL (1982 -2005), Cochrane Controlled Trials Register (Issue 4, 2005) and the Joanna Briggs Institute Evidence Library. In addition, the reference lists of retrieved papers, conference proceedings and the Internet, were scrutinised for additional trials. Selection Criteria  This review considered any English language randomised trials that investigated interventions conducted by the practice nurse for cardiovascular disease management or reduction of cardiac risk factors. Interventions conducted by specialist cardiac nurses in general practice were excluded. Outcomes measured included blood pressure, smoking cessation, total cholesterol, exercise, body weight/body mass index and cost-effectiveness. Results  Eighteen trials, reported in 33 papers, were included in the review. Ten trials investigated multifaceted interventions, while the remaining eight trials reported targeted interventions. Of the trials that reported multifaceted interventions, three trials investigated risk reduction in those with established cardiovascular disease, four trials focused on those with known cardiovascular disease risk factors and three trials included the general community. The eight trials which examined the efficacy of targeted interventions focused upon dietary intake (two trials), smoking cessation (three trials), weight reduction (one trial) and physical activity (two trials). The effect of both the multifaceted and targeted interventions on patient outcomes was variable. However, both the multifaceted and targeted interventions demonstrated similar outcome trends for specific variables. Improvements were demonstrated by most studies in blood pressure, cholesterol level, dietary intake and physical activity. The variation in outcome measures and contradictory findings between some studies makes it difficult to draw definitive conclusions. Conclusions  While interventions to reduce cardiovascular disease risk factors have produced variable results, they offer significant potential to assist patients in modifying their personal risk profile and should be developed. The public health importance of these changes is dependant upon the sustainability of the change and its effect on the health outcomes of these individuals. Further well-designed research is required to establish the effectiveness of practice nurse interventions for cardiovascular disease management and risk factor reduction in terms of patient outcomes and cost-effectiveness.

The evidence-based dentistry champions: a grassroots approach to the implementation of EBD

In order for evidence-based dentistry (EBD) to become part of decision making in practice, the most current and comprehensive research findings must be translated into practice. The use of Champions, influential individuals to support the transfer of knowledge among their peers, is one effective approach used by others in the health care field to successfully implement science research into clinical care. With the success of Champions in other health care areas, the American Dental Association (ADA) and the Journal of Evidence-Based Dental Practice, through an educational grant from Procter and Gamble, have launched a novel program to develop Evidence-Based Dentistry Champions. The EBD Champion program is developing a network of oral health care workers who will disseminate information about the application of an evidence-based approach to dental care and will serve as resources and mentors to their colleagues. The primary mechanism for developing the network of EBD Champions is through 3 annual EBD Champion Conferences, the first of which will be held at the ADA Headquarters in Chicago, IL, on May 2 and 3, 2008. The EBD Champion will serve as a resource to the practitioners in their communities, providing a grassroots approach to facilitating the implementation of an evidence-based approach to providing dental care.

Opportunistic screening for cardiovascular problems in rural and remote health settings

BACKGROUND

Cardiovascular disease is the leading cause of death in Australia and the United States. It is not known if routine electrocardiogram (ECG) assessment at the community level could identify a significant proportion of people with clinically relevant ECG anomalies who could benefit from intervention.

PURPOSE

This study aimed to elucidate the use of 3-lead ECG assessment by community nurses in rural and remote health settings. We report the findings obtained from 20-minute, lead II ECG recordings of 71 people who participated in a diabetes screening study.

RESULTS

Seven participants reported cardiac anomalies before screening. One or more ECG abnormalities were found in 45 participants. Of these, nine people who were otherwise asymptomatic showed abnormal ECG characteristics that warranted further investigation.

CONCLUSION

Although further research is needed, incorporating routine 3-lead ECG testing in rural and remote communities may improve general health in the community by providing early recognition of cardiac anomalies in otherwise asymptomatic individuals who may be amenable to treatment. This study has implications for community nurses on two levels: opportunistic screening, monitoring and evaluation.

Clinical leadership in contemporary clinical practice: implications for nursing in Australia

BACKGROUND

Leadership in the clinical practice environment is important to ensure both optimal patient outcomes and successive generations of motivated and enthusiastic clinicians.

AIM

The present paper seeks to define and describe clinical leadership and identify the facilitators and barriers to clinical leadership. We also describe strategies to develop clinical leaders in Australia. Key drivers to the development of nursing leaders are strategies that recognize and value clinical expertise. These include models of care that highlight the importance of the nursing role; evidence-based practice and measurement of clinical outcomes; strategies to empower clinicians and mechanisms to ensure participation in clinical decision-making.

KEY ISSUES

Significant barriers to clinical leadership are organizational structures that preclude nurses from clinical decision making; the national shortage of nurses; fiscal constraints; absence of well evaluated models of care and trends towards less skilled clinicians.

CONCLUSIONS

Systematic, strategic initiatives are required to nurture and develop clinical leaders. These strategies need to be collegial collaborations between the academic and health care sectors in order to provide a united voice for advancing the nursing profession.

Assessment of cognitive function in heart failure patients

BACKGROUND

Research on the cognitive capacity of heart failure patients is limited, with a paucity of benchmark information available for this population. It is highly likely that cognitive deficits affect patients' understanding of disease and treatment requirements, as well as limiting their functional capacity and ability to implement treatment plans, and undertake self-care.

AIMS

The purpose of this study was to establish a comprehensive neurocognitive profile of the heart failure patient through systematic neurocognitive assessment and to determine whether an association existed between severity of heart failure and cognitive abilities.

METHODS

Thirty-eight patients were recruited from the heart failure patient databases of two metropolitan hospitals in Melbourne, Australia. Participants were individually assessed using four standardised, internationally recognised neuropsychological tests that examined current and premorbid intelligence, memory and executive functioning.

RESULTS

Although there was no significant decline from premorbid general intellectual function, other specific areas of deficit, including impaired memory and executive functioning, were identified. There were no significant correlations between heart failure severity and the neurocognitive measures used.

CONCLUSION

The results support the need to recognise cognitive impairment in people with heart failure and to develop an abbreviated method of assessing cognitive function that can be easily implemented in the clinical setting. Identifying cognitive deficits in this population will be useful in guiding the content and nature of treatment plans to maximise adherence and minimise worsening of heart failure symptoms.

Activities of Home-Based Heart Failure Nurse Specialists: A Modified Narrative Analysis

• Background Heart failure nurse specialists strive to optimize patients’ outcomes in home-based settings.

• Objective To document the activities of home-based heart failure nurse specialists.

• Method A modified narrative analysis of clinical notes of home-based heart failure nurse specialists during a 12-month period was used.

• Results Data analysis revealed 7 key activities of home-based heart failure nurse specialists: (1) monitoring signs and symptoms and reinforcing patients’ self-management: identifying trends and appropriate action; (2) organization, liaison, and consultation with other health professionals to deal with changes in clinical status; (3) clarifying and reinforcing patients’ self-care strategies; (4) assisting patients in their desire to avoid institutionalized care; (5) identifying patients’ psychosocial issues: dealing with social isolation; (6) providing support: journeying with patients and patients’ families; and (7) helping patients and patients’ families deal with death and dying.

• Conclusions A major proportion of the activities of home-based heart failure nurse specialists are related to facilitating communication between health professionals and providing information and support to patients and patients’ families.

Australian nurses in general practice based heart failure management: implications for innovative collaborative practice

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.

Integrated, Collaborative Palliative Care in Heart Failure

BACKGROUND

Chronic heart failure (HF) is the only heart condition increasing in prevalence and is primarily a condition of aging. This condition has outcomes worse than many cancers; however, patients are often denied the benefits of palliative care with its important emphasis on symptom management, spirituality, and emotional health and focus on family issues.

AIM

To describe the development of a model of an integrated, consultative, palliative care approach within a comprehensive HF community-focussed disease management program.

METHOD

A collaborative model was developed following a systematic needs assessment and documentation of local resources. Principles underpinning this model were based upon fostering of communication, consultancy, and skill development. Within this model a health care system, based upon universal coverage, supported co-management of patients and their families. The place of death, level of social support available at home, and degree of palliative care involvement was documented in 121 consecutive deaths from 1999-2002.

FINDINGS

Following a period of skill sharing and program development, only 8.3% of HF patients in the collaborative program required specialized palliative care intervention for complex symptom management, carer support, and issues related to spirituality. Twenty percent of this cohort died in nursing homes underscoring the importance of supporting our nursing colleagues in this setting.

CONCLUSIONS

In spite of well-documented difficulties in determining prognosis, it is the St George experience that key principles of a palliative care strategy can be implemented in a HF disease management program with support and consultancy from expert palliative care services.

Synergizing acute care and palliative care to optimise nursing care in end-stage cardiorespiratory disease

Advances in the practice of medicine and nursing science have increased survival for patients with chronic cardiorespiratory disease. Parallel to this positive outcome is a societal expectation of longevity and cure of disease. Chronic disease and the inevitability of death creates a dilemma, more than ever before, for the health care professional, who is committed to the delivery of quality care to patients and their families. The appropriate time for broaching the issue of dying and determining when palliative care is required is problematic. Dilemmas occur with a perceived dissonance between acute and palliative care and difficulties in determining prognosis. Palliative care must be integrated within the health care continuum, rather than being a discrete entity at the end of life, in order to achieve optimal patient outcomes. Anecdotally, acute and critical care nurses experience frustration from the tensions that arise between acute and palliative care philosophies. Many clinicians are concerned that patients are denied a good death and yet the moment when care should be oriented toward palliation rather than aggressive management is usually unclear. Clearly this has implications for the type and quality of care that patients receive. This paper provides a review of the extant literature and identifies issues in the end of life care for patients with chronic cardiorespiratory diseases within acute and critical care environments. Issues for refinement of acute and critical care nursing practice and research priorities are identified to create a synergy between these philosophical perspectives.
