Purpose of review To review the application of intersectionality to heart failure. Intersectionality refers to the complex ways in which disenfranchisement and privilege intersect to reproduce and influence health and social outcomes. Recent findings Intersectionality challenges approaches that focus on a single or small number of socio-demographic characteristics, such as sex or age. Instead, approaches should take account of the nature and effects of a full range of socio-demographic factors linked to privilege, including: race and ethnicity, social class, income, age, gender identity, disability, geography, and immigration status. Although credible and well established across many fields -- there is limited recognition of the effects of intersectionality in research into heart disease, including heart failure. This deficiency is important because heart failure remains a common and burdensome syndrome that requires complex pharmacological and nonpharmacological care and collaboration between health professionals, patients and caregivers during and at the end-of-life. Summary Approaches to heart failure clinical care should recognize more fully the nature and impact of patients' intersectionality- and how multiple factors interact and compound to influence patients and their caregivers' behaviours and health outcomes. Future research should explicate the ways in which multiple factors interact to influence health outcomes. [ABSTRACT FROM AUTHOR]

Communities of practice could contribute to transformations in health professions education to meet complex and emerging challenges. However, little is known about the underlying mechanisms of communities of practice in this setting, and how context influences outcomes. To understand when, why and how communities of practice with health professions education faculty work to facilitate higher education change. A realist synthesis according to the RAMESES standards and steps described by Pawson and colleagues. Early scoping of the literature informed the development of an initial program theory to describe underlying assumptions about how communities of practice in higher education, implemented with health professions education faculty, were likely to work. The theory was tested and further refined through a realist synthesis. A systematic search for evidence using search terms 'faculty', 'communities of practice' and 'higher education' and related terms was supplemented with citation tracking and hand searching of significant authors and journals. Following study appraisal, data were extracted and synthesised from 21 manuscripts describing 16 communities of practice. The realist synthesis focused on identifying patterns in context-mechanism-outcome interactions, and the alignment with substantive theory. From the included manuscripts, ten context-mechanism-outcome configurations were identified that describe a range of individual, interpersonal and institutional outcomes of communities of practice with health professions education faculty and context-mechanism interactions that contribute to achieving these outcomes. This study expands theoretical understandings of how and why communities of practice work. There is value in communities of practice in the higher education sector, primarily in the field of health professions education. Communities of practice implemented in the context of complex change with participants who have a desire to participate can facilitate change in health professions education, including institutional level changes, through reflection, experiential learning and creating a shared agenda for change. Findings from this study can be used by policy and decision-makers within health education to best apply communities of practice to achieve meaningful outcomes. [ABSTRACT FROM AUTHOR]

Background: Self-care adherence remains low in patients with heart failure (HF); little is known about the influence of patients' values on self-care decisions and behaviors. Objectives: The aim of this study was to explore how participants living with HF perceive their values and how those values are reportedly expressed in self-care decision making. Methods: The Interpretative Phenomenological Analysis approach was used. Semistructured interviews were conducted with 12 patients 60 years or older; with New York Heart Association class II and III HF; and able to speak, read, and understand English. Participants recruited via convenience sampling (January--December 2016) from 2 urban sites in Western Canada. Results: Values were reported to pivotally influence HF self-care decisions and behaviors. Overarching themes addressed aspects of values and decision making: notably, directness and complexity. Two main types of values, functional and emotional values, were involved in both adherent and nonadherent decisions. Values were often in flux, with the pursuit of these values being frequently in conflict with physical ability and changing over time. Conclusion: Two types of values serve influence self-care decisions and adherence. As HF and its self-care prevent patients from pursuing their prioritized values, patients are often nonadherent. Thus, patients with HF should be supported to find alternative ways to enact their values. [ABSTRACT FROM AUTHOR]

• Previous studies often refer to patients' values wrongly. • The concept of patients' values often has been used interchangeably with attitudes and preferences. • Values are core and abstract beliefs, and the priority of values depends entirely on context. • Nursing practice should go beyond asking patients' preferences. • Patients' values need to be explored as the foundation for making health-related decisions. Patients' values are everywhere and nowhere in nursing: frequently invoked and associated with effective nursing care but seldom explicitly defined or subject to dedicated analysis. Clarification of the concept of patients' values is pivotal because respecting and supporting patients' values are widely recognized as crucial for ethical nursing care. Despite this and the pervasive employment of the term patients' values in theories, approaches, and clinical guidelines, the concept remains ambiguous. We sought to understand the key elements of the concept by investigating its use in theoretical and empirical literature. This study used Rodgers' evolutionary concept analysis approach. We found that values are core individual beliefs that function in hierarchical systems; however, in the context of disease, the priority assigned to values by the individual may change. This is important, given that values play a foundational role in health-related decisions, such as in the context of chronic diseases. Values are influenced by both individual intrinsic needs and the social context, but importantly, are involved in guiding decision-making. The attributes of the values may vary according to the context of the disease, the type of disease, and the decision at hand. [ABSTRACT FROM AUTHOR]

Background: The role of exercise training modality to attenuate left ventricular (LV) remodeling in heart failure patients with reduced ejection fraction (HFrEF) remains uncertain. The authors performed a systematic review and meta-analysis of published reports on exercise training (moderate-intensity continuous aerobic, high-intensity interval aerobic, and resistance exercise) and LV remodeling in clinically stable HFrEF patients.Methods: We searched MEDLINE, Cochrane Central Registry of Controlled Trials, CINAHL, and PubMed (2007 to 2017) for randomized controlled trials of exercise training on resting LV ejection fraction (EF) and end-diastolic and end-systolic volumes in HFrEF patients.Results: 18 trials reported LV ejection fraction (LVEF) data, while 8 and 7 trials reported LV end-diastolic and LV end-systolic volumes, respectively. Overall, moderate-intensity continuous training (MICT) significantly increased LVEF (weighted mean difference, WMD = 3.79%; 95% confidence interval, CI, 2.08 to 5.50%) with no change in LV volumes versus control. In trials ≥6 months duration, MICT significantly improved LVEF (WMD = 6.26%; 95% CI 4.39 to 8.13%) while shorter duration (<6 months) trials modestly increased LVEF (WMD = 2.33%; 95% CI 0.84 to 3.82%). High-intensity interval training (HIIT) significantly increased LVEF compared to control (WMD = 3.70%; 95% CI 1.63 to 5.77%) but was not different than MICT (WMD = 3.17%; 95% CI -0.87 to 7.22%). Resistance training performed alone or combined with aerobic training (MICT or HIIT) did not significantly change LVEF.Conclusions: In clinically stable HFrEF patients, MICT is an effective therapy to attenuate LV remodeling with the greatest benefits occurring with long-term (≥6 months) training. HIIT performed for 2 to 3 months is superior to control, but not MICT, for improvement of LVEF. [ABSTRACT FROM AUTHOR]

Abstract Background The mechanisms contributing to the success of cardiac rehabilitation (CR) are poorly understood and may include assessment, monitoring and review activities enabled by continuity of care and this is investigated in this study. Objectives To identify active assessment components of CR. Methods A qualitative study using focus groups and individual interviews. CR staff (n = 39) were recruited via professional association email and network contacts and organised into major themes. Results CR staff assessment strategies and timely actions undertaken provided a sophisticated post-discharge safety net for patients. Continuity of care enabled detection of adverse health indicators, of which medication issues were prominent. Interventions were timely and personalised and therefore likely to impact outcomes, but seldom documented or reported and thus invisible to audit. Conclusion CR staff assessment and intervention activities provide an unrecognised safety net of activities enabled by continuity of care, potentially contributing to the effectiveness of CR.

Background: Cognitive impairment is prevalent in heart failure (HF) with severe consequences, including increased risk of mortality and reduced ability to self-manage HF symptoms. Identifying cognitive impairment through screening would assist clinicians in managing HF and comorbid cognitive impairment. However, the accuracy of cognitive screening instruments for HF has not been adequately determined. Objective: The aim of this study was to determine the diagnostic accuracy of cognitive screening instruments in screening for mild cognitive impairment (MCI) in HF patients. Methods: A systematic review of major electronic bibliographic databases was searched from January 1999 to June 2013. Inclusion criteria were as follows: primary studies examining cognitive impairment in HF, administration of a cognitive screening instrument and neuropsychological test battery, and cognitive impairment indicated by performance on neuropsychological tests 1.5 SDs less than that of normative data. Methodological rigor of included publications was evaluated using 2 bias risk instruments: QUality Assessment of Diagnostic Accuracy Studies and STAndards for the Reporting of Diagnostic accuracy studies. The precision, accuracy, and receiver operating characteristic curves of the Mini Mental State Examination were computed. Results: From 593 citations identified, 8 publications met inclusion criteria. Risk of bias included selective HF patient samples, and no study examined the diagnostic test accuracy of the cognitive screening instruments. The Mini Mental State Examination had low sensitivity (26%) and high specificity (95%) with a score of 28 or less as the optimal threshold for MCI screening. Conclusions: Screening for cognitive impairment in HF is recommended; however, future studies need to establish the diagnostic accuracy of screening instruments of MCI in this population.

BACKGROUND: Self-care is at the foundation for living with a chronic condition such as heart failure (HF). Patients with HF express difficulty with translating self-care knowledge into understanding "how" to engage in these activities and behaviors. Understanding the strategies that patients develop to engage in self-care will help healthcare providers (HCPs) improve support for unmet self-care needs of HF patients. The purpose of this systematic review was to highlight strategies that HF patients use to accommodate self-care recommendations into the reality of their daily lives. METHODS: A systematic review using qualitative meta-synthesis was carried out. Included studies had to contain a qualitative component and data pertaining to self-care of HF from adults older than 18 years and be published as full papers/theses beginning 1995. Ten databases were searched until March 19, 2012. RESULTS: Of 1421 papers identified by the search, 47 were included. Studies involved the following: 1377 patients, 45% women, mean age of 67 years (range, 25-98 years), 145 caregivers, and 15 HCPs. Approaches to self-care reflected both perception- and action-based strategies and were a means to effectively manage HF. Although HF patients often expressed difficulty on how to integrate self-care recommendations into their daily lives, they developed intentional, planned strategies that harnessed previous experiences. CONCLUSIONS: Healthcare providers must appreciate that patients view self-care as an "adaptation" that they undertake to maintain their independence and quality of life. In addition, HCPs must recognize that because self-care is a process of learning over time from experience, an individualized approach that emphasizes how to self-care must be adopted for patients to develop the necessary HF self-care skills.

Background: The aim of this work was to identify the main contextual factors and processes that influence patients' self-care of heart failure (HF). Methods and Results: A systematic review was conducted with the use of qualitative meta-synthesis. Ten databases were searched up to March 19, 2012. Of the 1,421 papers identified by the systematic search, 45 studies were included in this meta-synthesis. To be included, studies had to contain a qualitative research component, data pertaining to self-care of HF from adults (≥18 y) and be published as full papers or theses since 1995. These studies involved: 1,398 patients (mean age 65.9 y), 180 caregivers, and 63 health professionals. Six main types of contextual factors were found to influence HF self-care in the studies: caregivers; social networks and social support; place; finances and financial capacity; work and occupation; and HF support groups and programs. Conclusion: HF self-care is influenced by contextual elements that fall outside of traditional elements of a HF self-care program. Inclusion of these elements may help to address the current concerns about poor adherence to self-management programs. [ABSTRACT FROM AUTHOR]

Abstract: Cardiovascular disease is among the leading causes of mortality and morbidity in Canada. Cardiac rehabilitation (CR) has a long robust history here, and there are established clinical practice guidelines. While the effectiveness of CR in the Canadian context is clear, only 34% of eligible patients participate, and strategies to increase access for under-represented groups (e.g., women, ethnic minority groups) are not yet universally applied. Identified CR barriers include lack of referral and physician recommendation, travel and distance, and low perceived need. Indeed there is now a national policy position recommending systematic inpatient referral to CR in Canada. Recent development of 30 CR quality indicators and the burgeoning national CR registry will enable further measurement and improvement of the quality of CR care in Canada. Finally, the Canadian Association of CR is one of the founding members of the International Council of Cardiovascular Prevention and Rehabilitation, to promote CR globally. [Copyright &y& Elsevier]

Abstract: People of low socioeconomic status (SES) are prone to premature coronary heart disease (CHD) and tend to have more risk factors and worse health and mortality. Yet, little is understood about the specific challenges faced by people of low SES with CHD in changing behavior around the consumption of dietary risk factors, such as salt, fat, and cholesterol, and adding heart-healthy foods, such as fruit, vegetables, lean meat, and fish. The aim of this study was to understand factors promoting and reducing willingness and capacity to consume a healthy diet in people of low SES with CHD. Qualitative research via semistructured interviewing and a critical realist theoretic framework was used, along with a questionnaire to provide context for the interviews. Food consumption and diet were not principally related to knowledge but were constrained by an ever-present scarcity of resources and the need to prioritize other daily living expenses perceived as being more important than diet. Having use of a vehicle also promoted access to dietary support from physicians and cardiac rehabilitation. [Copyright &y& Elsevier]

Chronic heart failure (CHF) is an increasingly common condition in high-income countries that has a large and negative impact on life quality and expectancy, and is associated with high financial costs. In Canada, CHF has an especially large impact on rural settings because of the higher proportion of older adults (aged >65 years) in these settings, and because care and outcomes tend to be more adverse in rural parts of the country compared to urban settings. Much can be done to reduce these burdens in terms of pharmacological, behavioural and health service strategies. However, rural patients tend to have worse care and outcomes than urban patients. Realizing the benefits of these strategies in Canada's rural settings requires consideration of underlying reasons for poor care and outcomes. We propose the main reasons for adverse outcomes are related to the nature of CHF and the combined influence of demographics, health services and the rural context. Nurses remain under-used in CHF management in Canada and can play a vital and influential role in reducing the burden of CHF in rural settings. To increase and improve nurses' roles, we recommend that nurses should support the development and adaptation of disease management programs in rural settings and promote the centrality of nursing in these programs. Nurses in or working with rural settings should seek to support and use tele-health technologies effectively and provide better support to lay caregivers. It will also be vital to increase the nursing capacity regarding specialist roles for CHF management. [ABSTRACT FROM AUTHOR]

Background: Cardiac rehabilitation and secondary prevention programs can prevent heart disease in high-risk populations. However, up to half of all patients referred to these programs do not subsequently participate. Although age, sex, and social factors are common predictors of attendance, to increase attendance rates after referral, the complex range of factors and processes influencing attendance needs to be better understood. Methods: A systematic review using qualitative meta-synthesis was conducted. Ten databases were systematically searched using 100+ search terms until October 31, 2011. To be included, studies had to contain a qualitative research component and population-specific primary data pertaining to program attendance after referral for adults older than 18 years and be published as full articles in or after 1995. Results: Ninety studies were included (2010 patients, 120 caregivers, 312 professionals). Personal and contextual barriers and facilitators were intricately linked and consistently influenced patients'' decisions to attend. The main personal factors affecting attendance after referral included patients'' knowledge of services, patient identity, perceptions of heart disease, and financial or occupational constraints. These were consistently derived from social as opposed to clinical sources. Contextual factors also influenced patient attendance, including family and, less commonly, health professionals. Regardless of the perceived severity of heart disease, patients could view risk as inherently uncontrollable and any attempts to manage risk as futile. Conclusions: Decisions to attend programs are influenced more by social factors than by health professional advice or clinical information. Interventions to increase patient attendance should involve patients and their families and harness social mechanisms. [Copyright &y& Elsevier]
