Cultural diversity in heart failure management: findings from the DISCOVER study (Part 2)

Self-management is a critical dimension in managing chronic conditions, particularly in heart failure (HF). Knowledge, attitudes and beliefs, relating to both illness and wellness, are strongly influenced by culture and ethnicity, impacting upon an individual's capacity to engage in self-care behaviours. Effective management of HF is largely dependent on facilitation of culturally informed, self-care behaviours to increase adherence to both pharmacological and non-pharmacological strategies. The Understanding the cultural experiences of individuals with chronic heart failure (CHF) in South East Health (DISCOVER) study is an exploratory, observational study investigating health patterns, information needs and the adjustment process for overseas-born people with HF living in Australia. An integrative literature review was augmented by qualitative data derived from key informant interviews, focus groups and individual interviews. A key finding of this study is that culture provides an important context to aid interpretations of attitudes, values, beliefs and behaviours, not only in illness but in health. While individual differences in attitudes and beliefs were observed among participants, common themes and issues were identified across cultural groups. Data from the DISCOVER study revealed the primacy of family and kinship ties. These relationships were important in making decisions about treatment choices and care plans. Participants also revealed the critical role of the 'family doctor' in assisting people and their families in brokering the health care system. In this study, heart disease was considered to be a significant condition but cancer was the condition that people both feared and dreaded the most, despite the high mortality rates of HF. This sample reported that religious and traditional beliefs became more important as people aged and considered their mortality. As HF is predominately a condition of ageing, the information derived from this study will assist clinicians to tailor health care service delivery for older people with HF, across multiple ethnic backgrounds.

Preparing for the worst while hoping for the best: the relevance of hope in the heart failure illness trajectory

BACKGROUND

Patients with heart failure have higher mortality rates than those with most malignant diseases. The heart failure illness trajectory is one of gradual decline characterized by unpredictable events such as acute decompensation of heart failure or a sudden cardiac death. Health professionals have an obligation to give patients and their families concise and honest information concerning their prognosis. The challenge exists to give what ostensibly may seem a bleak prognosis within a context of hope and optimism.

AIM

To explore the role of hope in heart disease and the potential utility of this construct in the development of nursing interventions.

METHODS

The electronic databases CINAHL, MEDLINE, EmBASE, and PSYCHlit were searched from 1982 to August 2004 using the key words "hope," "hopelessness," "heart disease," and "heart failure." Articles were subsequently sorted to meet the inclusion criteria of (1) a philosophical discussion of the construct of hope and/or (2) investigation of hope in heart disease.

RESULTS

This search retrieved 768 articles, and 24 met the inclusion criteria. Key findings from the review indicate that "hope" and "hopelessness" are underdeveloped, yet important constructs and conceptually linked with depression and spirituality. Intriguing findings from descriptive, observational studies have demonstrated the positive impact of expression of hope on cardiovascular outcomes. These findings need to be validated in randomized controlled trials.

CONCLUSIONS

This critical literature review has determined that "hope" is strongly associated with the individual's future orientation. Increased understanding of this concept may assist in refining patient-focused interventions and developing therapeutic strategies to enhance hope.

Maintaining hope in transition: a theoretical framework to guide interventions for people with heart failure

Theoretical frameworks provide a structure for the planning and delivery of nursing care and for research. Heart failure (HF), a condition of increasing prevalence in communities internationally, is responsible for high rates of morbidity, mortality, and great societal burden. The HF illness trajectory can be unpredictable and uncertain. Markers of transition, such as functional decline and increasing dependence, can signal the need for transition to a more palliative approach. This transition challenges clinicians to deliver information and interventions and to support patients and their families not only in relation to their physical status but also in the social, psychological, and existential dimensions. This article describes a theoretical framework, Maintaining Hope in Transition, informed by transition theory, to assist patients to cope with a diagnosis of HF and to guide development of nursing interventions. Transition theory provides a useful context to assist clinicians, patients, and their families adjust to the challenges inherent in a diagnosis of HF and negotiating the illness trajectory. Key factors acknowledged in the Maintaining Hope in Transition framework that determine its utility in models of care for HF patients are (1) acknowledging the changing of life circumstances, (2) restructuring reality, (3) dealing with vulnerability, (4) achieving normalization, and (5) resolving uncertainty. It is likely that incorporation of these factors in care planning, information, and interventions can facilitate patients' and their families' abilities to negotiate the HF illness trajectory, particularly in the advanced stages.

Residential aged care: the last frontier for palliative care

AIM

This paper is a report of an explorative study describing the perceptions and beliefs about palliative care among nurses and care assistants working in residential aged care facilities in Australia.

BACKGROUND

Internationally, the number of people dying in residential aged care facilities is growing. In Australia, aged care providers are being encouraged and supported by a positive policy platform to deliver a palliative approach to care, which has generated significant interest from clinicians, academics and researchers. However, a little is known about the ability and capacity of residential aged care services to adopt and provide a palliative approach to care.

METHODS

Focus groups were used to investigate the collective perceptions and beliefs about palliative care in a convenience sample of nurses and care assistants working in residential aged care facilities in Australia. Thematic content analysis was used to analyse the data, which were collected during 2004.

RESULTS

Four major themes emerged: (1) being like family; (2) advocacy as a key role; (3) challenges in communicating with other healthcare providers; (4) battling and striving to succeed against the odds. Although participants described involvement and commitment to quality palliative care, they also expressed a need for additional education and support about symptom control, language and access to specialist services and resources.

CONCLUSION

The residential aged care sector is in need of support for providing palliative care, yet there are significant professional and system barriers to care delivery. The provision of enhanced palliative care educational and networking opportunities for nurses and care assistants in residential aged care, augmented by a supportive organizational culture, would assist in the adoption of a palliative approach to service delivery and requires systematic investigation.

An exploration of the usefulness of motivational interviewing in facilitating secondary prevention gains in cardiac rehabilitation

Motivational interviewing is a client-centered, directive counseling approach aimed at promoting motivation in clients to change certain behaviors. Its effect is to reduce defensiveness and promote disclosure, engagement, and participation, thereby motivating the client to make behavioral changes. Motivational interviewing marries well with the principles of cardiac rehabilitation (CR) in terms of increasing motivation among CR clients, promoting a client-centered approach and in the cost- and time-effective practices of CR. Very little research has been conducted examining the effectiveness of motivational interviewing in enhancing CR outcomes. This article discusses research that has been conducted in motivational interviewing that relates to the components of CR, provides examples of how motivational interviewing can be applied to CR, and recommends further exploration, development, and investigation of the usefulness of motivational interviewing in the field of CR.

The relationships among workplace stressors, coping methods, demographic characteristics, and health in Australian nurses

Nursing is known to be stressful. Stress detrimentally can influence job satisfaction, psychological well-being, and physical health. There is a need for increased understanding of the stress that nurses experience and how best to manage it. Three hundred twenty Australian acute care public hospital nurses participated in a study by completing four questionnaires that examined (a) how various workplace stressors relate to ways of coping, demographic characteristics, and physical and mental health and (b) which workplace stressors, coping mechanisms, and demographic characteristics were the best predictors of physical and mental health. Significant correlations were found between stressors and physical and mental health. Multiple regression showed age to be the only significant predictor of physical health. The best coping predictors of mental health were escape-avoidance, distancing, and self-control. Other significant predictors of mental health were support in the workplace, the number of years worked in the unit, and workload. Mental health scores were higher for nurses working more years in the unit and for those who used distancing as a way of coping. Mental health scores were lower for nurses who used escape-avoidance, lacked workplace support, had high workload, and used self-control coping. The findings have implications for organizational management, particularly in terms of recommendations for stress management, social support, and workload reduction.

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.

Enhancing palliative care delivery in a regional community in Australia

Although access to palliative care is a fundamental right for people in Australia and is endorsed by government policy, there is often limited access to specialist palliative care services in regional, rural and remote areas. This article appraises the evidence pertaining to palliative care service delivery to inform a sustainable model of palliative care that meets the needs of a regional population on the mid-north coast of New South Wales. Expert consultation and an eclectic literature review were undertaken to develop a model of palliative care service delivery appropriate to the needs of the target population and resources of the local community. On the basis of this review, a local palliative care system that is based on a population-based approach to service planning and delivery, with formalised integrated network agreements and role delineation between specialist and generalist providers, has the greatest potential to meet the palliative care needs of this regional coastal community.

Correlates of self-rated successful aging among community-dwelling older adults

OBJECTIVE

There is no consensus on how to define successful aging. The authors sought to determine the correlates of self-rated successful aging as well as its correspondence with major researcher-defined criteria.

METHODS

Participants were 205 community-dwelling adults over age 60. A questionnaire survey asked the participants to rate their own degree of successful aging and inquired about demographic characteristics, medical history, activity levels, resilience, daily functioning, and health-related quality of life (Medical Outcomes study 36-item Short-Form [MOS-SF-36]). Participants' subjective ratings of successful aging were contrasted with sets of researcher-defined criteria, and correlates of subjectively rated successful aging were examined.

RESULTS

Ninety-two percent of the participants rated themselves as aging successfully. A majority of them also met other research criteria for successful aging such as independent living, mastery/growth, and positive adaptation but not those requiring an absence of chronic medical illness or physical disability. Higher SF-36 scores as compared with a published sample indirectly corroborated participants' subjectively rated successful aging. Subjective ratings of successful aging were significantly correlated with higher scores on health-related quality of life as well as resilience, greater activity, and number of close friends but not with several demographic characteristics.

CONCLUSION

Most community-dwelling older adults viewed themselves as aging successfully despite having chronic physical illnesses and some disability. Longitudinal studies of the reliability and validity of subjective ratings of successful aging are warranted.

The use of a systemic prime/mucosal boost strategy with an equine influenza ISCOM vaccine to induce protective immunity in horses

In horses, natural infection confers long lasting protective immunity characterised by mucosal IgA and humoral IgGa and IgGb responses. In order to investigate the potential of locally administered vaccine to induce a protective IgA response, responses generated by vaccination with an immunostimulating complex (ISCOM)-based vaccine for equine influenza (EQUIP F) containing A/eq/Newmarket/77 (H7N7), A/eq/Borlänge/91 (H3N8) and A/eq/Kentucky/98 (H3N8) using a systemic prime/mucosal boost strategy were studied. Seven ponies in the vaccine group received EQUIP F vaccine intranasally 6 weeks after an initial intramuscular immunisation. Following intranasal boosting a transient increase in virus-specific IgA was detected in nasal wash secretions. Aerosol challenge with the A/eq/Newmarket/1/93 reference strain 4 weeks after the intranasal booster resulted in clinical signs of infection and viral shedding in seven of seven influenza-naive control animals whereas the seven vaccinated ponies had statistically significantly reduced clinical signs and duration of virus excretion. Furthermore, following this challenge, significantly enhanced levels of virus-specific IgA were detected in the nasal washes from vaccinated ponies compared with the unvaccinated control animals. These data indicate that the intranasal administration of EQUIP F vaccine primes the mucosal system for an enhanced IgA response following exposure to live influenza virus.

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.

Issues and challenges in international doctoral education in nursing

Education is a driving force in improving the health and welfare of communities globally. Doctoral education of nurses has been identified as a critical factor for provision of leadership in practice, scholarship, research, policy and education. Since the genesis of doctoral education in nursing in the USA in the 1930s, this movement has burgeoned to over 273 doctoral programs in over 30 countries globally. The present article seeks to identify the issues and challenges in nursing doctoral education globally, and those encountered by doctoral program graduates in meeting the challenges of contemporary health care systems. Information was derived from a comprehensive literature review. Electronic databases and the Internet, using the Google search engine, were searched using the key words "doctoral education"; "nursing"; "International Network for Doctoral Education in Nursing"; "global health"; "international research collaboration". Doctoral education has been a critical force in developing nurse leaders in education, management, policy and research domains. An absence of consensus in terminology and of accurate minimum data sets precludes comparison and debate across programs. The complexity and dynamism of contemporary globalized communities render significant challenges in the conduct of doctoral programs. Addressing funding issues and faculty shortages are key issues for doctoral programs, especially those in developing countries, to achieve an identity uniquely their own. These challenges can also afford considerable opportunities for discussion, debate and the formulation of innovative and collaborative solutions to advance nursing knowledge and scholarship. In spite of discrete differences between countries and regions, the similarities in the issues facing the development of doctoral programs internationally are more striking than the differences. The harnessing of a global collective to address these issues will likely serve to not only forge the future viability of doctoral education of nurses but to improve the health and well-being of communities. This paper proposes international collaborative strategies to address a number of the challenges identified.

Immune responses and protective efficacy in ponies immunised with an equine influenza ISCOM vaccine containing an 'American lineage' H3N8 virus

Protective responses generated by vaccination with an immuno-stimulating complex (ISCOM)-based vaccine for equine influenza (EQUIP F), containing a new 'American lineage' H3N8 virus, were studied. Seven ponies in the vaccine group received two intramuscular injections of EQUIP F given 6 weeks apart. Aerosol challenge with an A/eq/Newmarket/1/93 reference strain 4 weeks after booster vaccination resulted in clinical signs of infection and viral shedding in 7 influenza-naive control animals whereas the vaccinated ponies were significantly protected from both clinical signs and virus excretion. Influenza virus-specific IgG responses in serum following immunisation with the ISCOM vaccine were predominantly of the IgGa and IgGb sub-isotypes, a pattern similar to that generated by equine influenza virus infection. However, in contrast to the response following infection, virus-specific antibody responses in nasal washes following immunisation were characterised by the presence of IgG but not IgA.These results demonstrated that an ISCOM-based vaccine containing A/eq/Kentucky/98 provides strong protective immunity against challenge with an 'American lineage' H3N8 reference virus.

Do Bone Marrow Micrometastases Correlate with Sentinel Lymph Node Metastases in Breast Cancer Patients?

BACKGROUND

Sentinel lymph node biopsies (SLNB) are used to detect axillary metastases as an important prognostic indicator for breast cancer patients. Bone marrow micrometastases (BMM) have also been shown to predict prognosis. This study examines whether SLNB and BMM are associated.

STUDY DESIGN

A retrospective analysis was performed on 124 stages I to III breast cancer patients treated with mastectomy or lumpectomy, SLNB, and bone marrow aspiration between 1997 and 2003. SLNB were examined for the presence of metastases by hematoxylin and eosin (H&E) stains and also by immunohistochemistry (IHC) for lymph nodes negative by H&E. The kappa statistic was used to evaluate the association (agreement) between SLNB and BMM.

RESULTS

In this study population, 36 patients (29%) had micrometastases detected in their bone marrow, and 51 patients (41%) had positive sentinel lymph nodes. Of the patients with positive BMM (n = 36), 53% (19 of 36) had positive SLNB (14 of 19 by H&E and 5 of 19 by IHC). In patients with negative BMM (n = 88), 36% (32 of 88) had a positive SLNB (27 of 32 by H&E and 5 of 32 by IHC). The kappa statistic and associated 95% confidence interval indicated poor agreement between SLNB and BMM (kappa = 0.15; 95% CI = -0.03, 0.32).

CONCLUSIONS

There was poor agreement between axillary metastases and micrometastases detected in the bone marrow. This study suggests that BMM and axillary metastases are not concordant findings in most patients.

Palliative care for end-stage dementia: a discussion of the implications for education of health care professionals

The increasing burden of chronic disease demands that palliative care clinicians address the needs of patients with non-malignant disease. This discussion document seeks to address some of the challenges to providing palliative care for end-stage dementia (ESD) and the need for skill enhancement in key providers of care. In spite of the intent, there is an apparent lack of appropriate, co-ordinated and comprehensive palliative care available for these individuals and their families. There is an absence of well-articulated models to assist health care providers of ESD clients. It would appear that the development and evaluation of guidelines, implementation of education programs and collaborative associations between palliative and aged-care providers of care are key strategies to facilitate palliative care for ESD clients.

Efficacy of a recombinant equine influenza vaccine against challenge with an American lineage H3N8 influenza virus responsible for the 2003 outbreak in the United Kingdom

Fifteen influenza-naive Welsh mountain ponies were randomly assigned to three groups of five. A single dose of a recombinant ALVAC vaccine was administered intramuscularly to five of the ponies, two doses, administered five weeks apart, were administered to five, and the other five served as unvaccinated, challenge controls. Two weeks after the completion of the vaccination programme, the ponies were all challenged by exposure to an aerosol of influenza virus A/eq/Newmarket/5/03. Their clinical signs were scored daily for 14 days according to a standardised scoring protocol, and nasal swabs were taken daily for 10 days to monitor the excretion of virus. The challenge produced severe clinical signs of influenza (fever, coughing, nasal discharge and dyspnoea) in all five control ponies, but the vaccinated ponies developed only mild disease, consisting of a serous nasal discharge lasting for only one day. The excretion of virus was almost completely suppressed in the vaccinated ponies, but the control ponies shed the virus for up to seven days after the challenge.

Role stress in nurses: Review of related factors and strategies for moving forward

The aim of this paper was to review the literature on factors related to role stress in nurses, and present strategies for addressing this issue based on the findings of this review while considering potential areas for development and research. Computerized databases were searched as well as hand searching of articles in order to conduct this review. This review identified multiple factors related to the experience of role stress in nurses. Role stress, in particular, work overload, has been reported as one of the main reasons for nurses leaving the workforce. This paper concludes that it is a priority to find new and innovative ways of supporting nurses in their experience of role stress. Some examples discussed in this article include use of stress education and management strategies; team-building strategies; balancing priorities; enhancing social and peer support; flexibility in work hours; protocols to deal with violence; and retention and attraction of nursing staff strategies. These strategies need to be empirically evaluated for their efficacy in reducing role stress.
