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.

Current Challenges and Issues Facing Nursing in Australia

This column is a discussion of nursing in Australia. The authors present current challenges and issues related to recruitment and retention, an aging workforce, violence and bullying, diversity, undergraduate and graduate education, professional development, information technology, clinical pathways, models of care delivery, and funding models. They also present what is happening in Australia in relation to nursing’s scope of practice, development of the nurse practitioner role, nursing leadership, and nursing research.

An insight into Australian nurses’ experience of withdrawal/withholding of treatment in the ICU

BACKGROUND

The success of biotechnology has created moral and ethical dilemmas concerning end-of-life care in the Intensive Care Unit (ICU). Whilst the competent individual has the right to refuse or embrace treatment, ICU patients are rarely able to exercise this right. Thus, decision-making is left to medical professionals and family/significant others.

AIM

This study aimed to explore the lived experience of ICU nurses caring for clients having treatment withdrawn or withheld, and increase awareness and understanding of this experience amongst other health professionals.

METHODS

Van Manens' (1990) phenomenological framework formed the basis of this study as it provided an in-depth insight into the human experience. A convenience sample of ten ICU Nurses participated in the study. Conversations were transcribed verbatim and analysed using a process of thematic analysis.

RESULTS

Five major themes emerged during the analysis. These were: (1) comfort and care, (2) tension and conflict, (3) do no harm, (4) nurse-family relationships and (5) invisibility of grief and suffering.

CONCLUSION

The experience of providing care for the adult having treatment withdrawn or withheld in the ICU represents a significant personal and professional struggle. Improvements in communication between health professionals, debriefing and education about the process of withdrawing or withholding treatment would be beneficial to both staff and families and has the potential to improve patient care and reduce burden on nurses.

Validation of the Alder Hey Triage Pain Score

AIMS

To describe the validation and reliability of a new pain tool (the Alder Hey Triage Pain Score, AHTPS) for children at triage in the accident and emergency (A&E) setting.

METHODS

A new behavioural observational pain tool was developed because of dissatisfaction with available tools and a lack of confidence in self-assessment scores at triage. The study was conducted in a large paediatric A&E department; 575 children (aged 0-16 years) were included. Inter-rater reliability and various aspects of validity were assessed. In addition this tool was compared to the Wong-Baker self-assessment tool. The children were concurrently scored by a research nurse and triage nurses to assess inter-rater reliability. Construct validity was assessed by comparing the research nurse's triage score with the research nurse reassessment score after intervention and/or analgesia. Known group construct validity was assessed by comparing the research nurse's score at triage with the level of pain of the condition as judged by the discharge diagnosis. Predictive validity was assessed by comparing the research nurse's AHTPS with the level of analgesia needed by each patient. The AHTPS was also compared to a self-assessment score.

RESULTS

A high level of inter-rater reliability, kappa statistic 0.84 (95% CI 0.80 to 0.88), was shown. Construct validity was well demonstrated; known group construct validity and predictive validity were also demonstrated to a varying degree.

CONCLUSIONS

Results support the use of this observational pain scoring tool in the triage of children in A&E.

Community health nursing in Australia: a critical literature review and implications for professional development

BACKGROUND

Increasing emphasis on community-based mandates an examination of the community health nurse (CHN).

AIM

A critical literature review of the CHN role internationally, with an emphasis on Australia, was undertaken in order to understand historical precedents and inform policy and strategic directions for the CHN.

METHOD

A search of the CINAHL, EMBASE, and COCHRANE electronic data-bases from 1982 to June 2002 using community' and 'nursing' as key words and hand searching of books and government reports was undertaken.

FINDINGS

This search strategy revealed a lack of literature compared with other areas of nursing. Key themes emerging from this review are: (1) an absence of clear role definitions and lack of clarity of roles; (2) variability in educational requirements for CHNs; (3) diminished CHN power in policy decision making; (3) conflicting role expectations between different facets of the health care system; (4) underutilisation and untapped potential of the role of the CHN in the contemporary health care system; (5) the emerging influence of specialist nurses in community based-care; (6) uptake of traditional nursing roles by non-nurses and (7) an absence of a cohesive model of professional development of CHN that is able to articulate with contemporary social, political and economic trends in health care delivery.

CONCLUSIONS

Community health nursing in Australia has a low professional profile when compared to other nursing specialties. An emerging issue, gleaned from the literature review is the tension and debate between specialist and generalist services. It is apparent from this review that CHN have to more actively participate in research and peer reviewed debate in order to have their voice heard and promote their unique and valuable contribution to the nursing profession and the health care system.

Patient-centered Needs Assessment

Determining an individual's unique perspective of an illness experience remains a challenge for clinicians, administrators, and researchers. A range of concepts and psychometric measures have been developed and evaluated to capture this information. These include patient satisfaction, quality of life, and utility measures. Needs assessment as a tool for evaluating perceptions of health status and determining patient satisfaction and treatment plans has been explored in oncology. Studies have demonstrated that a high proportion of patients have unmet needs in relation to activities of daily living, information sources, and comfort. Heart failure (HF), a condition with significant individual and societal burden, mirrors the illness of experience of cancer, as individuals process issues related to prognosis, treatment regimens, and decreased functional status. A needs-based assessment of health status, expectations, and perceptions is patient-centered and has the capacity to not only evaluate current health status but also plan and project care plans. Needs assessment is a dynamic construct rather than a point in time consistent with other assessment modalities, such as quality of life. Multidimensional needs assessment allows for planning and projection of needs, not only on an individual but also a population basis. Implicit in the exploration of needs is an expectation of level of care to be provided, from both the provider and recipient of care. In many instances a misalignment may exist between services and resources available to the individual. This article seeks to provide a theoretical justification for the development of a needs assessment instrument for patients with HF and to discuss the rationale of this method of assessment to create better alignment and resources with patients needs and expectations.

Non-valvular atrial fibrillation and stroke: Implications for nursing practice and therapeutics

Atrial fibrillation (AF) is the most common sustained cardiac rhythm disturbance and is increasing in prevalence due to the ageing of the population, and rates of chronic heart failure. Haemodynamic compromise and thromboembolic events are responsible for significant morbidity and mortality in Australian communities. Non-valvular AF is a significant predictor for both a higher incidence of stroke and increased mortality. Stroke affects approximately 40,000 Australians every year and is Australia's third largest killer after cancer and heart disease. The burden of illness associated with AF, the potential to decrease the risk of stroke and other embolic events by thromboprophylaxis and the implications of this strategy for nursing care and patient education, determine AF as a critical element of nursing practice and research. A review of the literature was undertaken of the CINAHL, Medline, EMBASE and Cochrane Databases from 1966 until September 2002 focussing on management of atrial fibrillation to prevent thrombotic events. This review article presents key elements of this literature review and the implications for nursing practice.

Traditional Chinese Medicine and heart disease: what does Western medicine and nursing science know about it?

BACKGROUND

Interest in Traditional Chinese Medicine (TCM) is growing rapidly beyond China. This interest is driven by a combination of factors including recognition of potential benefits of TCM; dissatisfaction with the traditional Western medical model; an increasing commitment to holistic care and increasing evidence for the interaction of psychological factors and outcomes of disease and treatment and health consumer demand.

AIMS

This review article was prompted by the need to understand and interpret the increasing trend towards the use of TCM in heart disease. In particular, this article defines and describes TCM, and analyses implications and challenges for Western health care delivery models.

LITERATURE SEARCH

This article provides a review of accessible evidence, to English speaking health care professionals. The CINAHL, MEDLINE, HealthSTAR, Academic ASAP and Cochrane databases were searched, identifying literature published from 1982. Search engines on the Internet were also used. Examples of keywords used were "Traditional Chinese Medicine" and "heart".

CONCLUSION

Difficulties in accessing information regarding TCM have implications for health education in coronary heart disease and patient safety. The rapid uptake of TCM in both Western and Chinese societies mandates an understanding of the principles and potential interactions when TCM is complemented with Western medical treatment for heart disease. Development of this knowledge and understanding is essential in order to provide safe and effective health care to patients who use combination therapies.

Comparison of a Commercial Reversed Passive Latex Agglutination Assay to an Enzyme Immunoassay for the Detection of Shiga Toxin-Producing Escherichia coli

A multicenter study was performed to compare the performance of a prototypic reversed passive latex agglutination assay (VTEC Screen "Seiken"; Denka-Seiken, Japan) with the Premier EHEC Enzyme Immunoassay (Meridian Diagnostics, USA) for the detection of Shiga toxin in 554 diarrheal stool samples. Standard culture on sorbitol MacConkey agar and the use of latex agglutination reagents were included to identify the Escherichia coli O157, O26 and O111 serotypes. There was 99% agreement between the VTEC screen and enzyme immunoassay (kappa=0.823). Seventeen samples were positive for toxin by one or both assays. One toxin-positive sample using the enzyme immunoassay and four positive samples using the VTEC Screen could not be confirmed. Serotypes identified included: O157:H7 (n=8), O26 (n=2), O111 (n=1) and O45:H2 (n=1). The VTEC screen is easy to perform and comparable to the Meridian EHEC test for detection of Shiga toxin in clinical samples.

Optimising vaccination strategies in equine influenza

A stochastic model of equine influenza (EI) is constructed to assess the risk of an outbreak in a Thoroughbred population at a typical flat race training yard. The model is parameterised using data from equine challenge experiments conducted by the Animal Health Trust (relating to the latent and infectious period of animals) and also published data on previous epidemics (to estimate the transmission rate for equine influenza). Using 89 ponies, an empirical relationship between pre-challenge antibody and the probability of becoming infectious is established using logistic regression. Changes in antibody level over time are quantified using published and unpublished studies comprising 618 ponies and horses. A plausible Thoroughbred population is examined over the course of a year and the model is used to assess the risk of an outbreak of EI in the yard under the current minimum vaccination policy in the UK. The model is adapted to consider an alternative vaccination programme where the frequency of vaccination in older horses (2-year-olds and upwards) is increased. Model results show that this practical alternative would offer a significant increase in protection. Spread of infection between yards is also considered to ascertain the risk of secondary outbreaks.

Impact of stem cell donation modality on normal donor quality of life: a prospective randomized study

As part of a previously reported trial comparing granulocyte-colony stimulating factor (G-CSF) stimulated bone marrow and peripheral blood stem cells (PBSCs) in allogeneic stem cell transplantation, we included a questionnaire to compare donor morbidity and long-term complications between the two donation procedures. Bone marrow donation was associated with significantly more donors experiencing localized pain at the donation site compared to PBSC collection. However, this was not associated with any increased delay in returning to normal activity. Although a minority of bone marrow donors suffered chronic pain at the donation site, no serious long-term side effects relating to G-CSF stimulated stem cell donation were identified.

Cardiorespiratory Nurses’ Perceptions of Palliative Care in Nonmalignant Disease: Data for the Development of Clinical Practice

Nurses lack a comprehensive body of scientific knowledge to guide the palliative care of patients with nonmalignant conditions. Current knowledge and practice reveal that nurses in many instances are not well prepared to deal with death and dying. Focus groups were used in an exploratory study to examine the perceptions of palliative care among cardiorespiratory nurses (n = 35). Content analysis was used to reveal themes in the data. Four major themes were found: (1) searching for structure and meaning in the dying experience of patients with chronic disease, (2) lack of a treatment plan and a lack of planning and negotiation, (3) discomfort in dealing with death and dying, and (4) lack of awareness of palliative care philosophies and resources. The information derived from this sample of cardiorespiratory nurses represents a complex interplay between personal, professional, and organizational perspectives on the role of palliative care in cardiorespiratory disease. The results of the study suggest a need for nurses to be equipped on both an intellectual and a practical level about the concept of palliative care in nonmalignant disease.

A prospective study of circulating mutant KRAS2 in the serum of patients with colorectal neoplasia: strong prognostic indicator in postoperative follow up

BACKGROUND AND AIMS

Mutant tumour derived DNA has been detected in the sera of colorectal cancer patients. We investigated if mutant serum KRAS2 was detectable preoperatively in a large group of patients with colorectal neoplasia. A prospective study of 94 patients who underwent putative curative resection for colorectal carcinoma (CRC) was performed to ascertain if serum mutant KRAS2 could be used postoperatively as a disease marker.

METHODS

Preoperative sera from 78 patients were analysed (group A). Sera from 94 patients were obtained three monthly for up to three years during the postoperative period (group B). Codon 12 and 13 KRAS2 mutations were analysed in matched tumour and serum samples.

RESULTS

In the preoperative group (group A), KRAS2 mutation was found in 41/78 (53%) tumours and in 32/78 (41%) preoperative sera. Of 41 tumour KRAS2 mutation positive cases, 31/41 (76%) had an identical serum mutation detectable. In group B, the postoperative follow up group, 60/94 cases were primary tumour KRAS2 mutation positive. Of these 60, 16/60 (27%) became persistently serum mutant KRAS2 positive postoperatively. Ten of 16 (63%) of these developed a recurrence compared with only 1/44 (2%) patients who remained serum mutant negative (odds ratio 71.7 (95% confidence interval 7.7-663.9; p=0.0000). None of 34 tumour mutation negative cases became serum mutant KRAS2 positive postoperatively, despite recurrence in 9/34 patients. The relative hazard of disease recurrence in postoperative serum mutant KRAS2 positive patients was 6.37 (2.26-18.0; p=0.000).

CONCLUSIONS

Serum mutant KRAS2 can be detected preoperatively in all stages of colorectal neoplasia. Postoperatively, serum mutant KRAS2 is a strong predictor of disease recurrence, stronger even than Dukes' stage of disease, and thus shows potential for use in clinical practice as a marker of preclinical disease recurrence.

A continuing educational initiative to develop nurses' mental health knowledge and skills in rural and remote areas

At a time of ever increasing mental health problems in Australian society, the nursing profession is beset by problems of an insufficient workforce specialising in this area. Not only is there a shortage of suitable trained specialist mental health nurses, but undergraduate nursing programs inadequately prepare students for practical mental health nursing. Fewer students are enrolling in mental health nursing, and many nurses are leaving the workforce. A particular problem in rural Australia is that there is a lack of specialist mental health services, and nurses are being increasingly relied upon to perform the role of mental health nurse despite lacking the necessary qualifications and experience.This paper aims to describe the development, implementation and evaluation of a mental health continuing education program for nurses employed in rural and remote areas of New South Wales (NSW), Australia. This was a collaborative educational initiative mounted by the NSW Health Department (who funded the project), a rural university and a number of regional health service partners. The paper includes information on how this program was conceived, developed and conducted through distance education mode. It also evaluates the efficacy of this program as perceived by 202 out of 303 participants. Overall the project was rated very favourably, and represents a cost-effective, convenient method of enabling rural and regional nurses to update and improve their skills in mental health nursing.

Cultural aspects of adjustment to coronary heart disease in Chinese-Australians: a review of the literature

BACKGROUND

The burden of illness associated with Coronary Heart Disease (CHD) has determined this as a key focus for research at a basic science, individual and population level. Although considerable research has been conducted on specific aspects of the experience of CHD, such as anxiety or depression, there is a lack of research investigating the global aspects of the illness experience from the individual's perspective. Furthermore, there is a paucity of research examining the cross-cultural experiences of patients from Non-English Speaking Backgrounds (NESB). Given the multicultural nature of Australian society, and that health and illness are culturally constructed experiences (Manderson 1990), it is important to include the perspectives of people from minority cultures in health related research in order to provide culturally sensitive and appropriate health care and information during an illness. Further, the potential to prevent and modulate the course of CHD, by strategies such as smoking cessation and lipid management, mandate a health promotion agenda based on equity and access for all members of society.

AIMS

This article discusses cultural aspects of CHD in relation to nursing and allied health care during the recovery phase of an acute cardiac event. It reviews the research that has been conducted in this area, focusing on the Chinese-Australian population.

LITERATURE SEARCH

The CINAHL, MEDLINE, FAMILY (Australian Family and Society Abstracts Database), PsychINFO, and Multicultural Australian and immigration Studies (MAIS) databases were searched, identifying literature published from 1982. Keywords used were Chin* (Chinese, China), Asia* (Asia, Asian), experience, adjustment, psychological, heart, coronary, cardiac, health and services. Reports not written in English were excluded. Australian Government reports were also searched, as well as hand searching of nursing and medical textbooks. These searches resulted in over 1000 articles. However, only around 50 were relevant for this review.

IMPLICATIONS

Chinese-Australians are one of the fastest growing populations in Australia, and are at increased risk of CHD upon settling to Australia. Recommendations for future research and for the practice of nursing are provided.

Barriers to participation in and adherence to cardiac rehabilitation programs: a critical literature review

Despite the documented evidence of the benefits of cardiac rehabilitation (CR) in enhancing recovery and reducing mortality following a myocardial infarction, only about one third of patients participate in such programs. Adherence to these programs is an even bigger problem, with only about one third maintaining attendance in these programs after 6 months. This review summarizes research that has investigated barriers to participation and adherence to CR programs. Some consistent factors found to be associated with participation in CR programs include lack of referral by physicians, associated illness, specific cardiac diagnoses, reimbursement, self-efficacy, perceived benefits of CR, distance and transportation, self-concept, self-motivation, family composition, social support, self-esteem, and occupation. Factors associated with non-adherence include being older, female gender, having fewer years of formal education, perceiving the benefits of CR, having angina, and being less physically active during leisure time. However, many of the studies have methodologic flaws, with very few controlled, randomized studies, making the findings tentative. Problems in objectively measuring adherence to unstructured, non-hospital-based programs, which are an increasingly popular alternative to traditional programs, are discussed. Suggestions for reducing barriers to participation and adherence to CR programs, as well as for future research aimed at clearly identifying these barriers, are discussed.

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.
