Shared heart failure knowledge and self-care outcomes in patient-caregiver dyads

Do Interventions Meet the Needs of Caregivers of Cardiac Patients?: A Scoping Review

BACKGROUND

Interventions targeting the needs of caregivers of cardiac patients are few, and in most cases, no effect is found on caregivers' well-being. A closer look at the existing interventions will provide a solid foundation for future efforts to develop effective interventions targeted at caregivers of cardiac patients.

OBJECTIVE

The study's objective was to scrutinize and discuss interventions targeting caregivers of cardiac patients and contribute to reflections that will improve future interventions.

METHODS

Systematic scoping of the literature within the field was conducted through a literature search in PubMed, EMBASE, CINAHL, PsycINFO, and Cochrane Library from January 2011 to May 2022. The development of search terms and inclusion criteria was inspired by the Patient problem/population, Intervention, Comparison/Control, and Outcome approach, and the Medical Research Council framework for developing and evaluating complex interventions served as the underlying basis for the analysis.

RESULTS

Eleven articles were included. The interventions reported in the articles were generally not systematically developed and did not include field-specific, methodological, and theoretical reflections. Furthermore, the development process behind the studies seemed not to be transparent.

CONCLUSIONS

Lack of systematic methodology and methodological transparency in the reviewed studies hinders further testing of interventions and might explain lack of evidence for effective interventions within the field. More systematic, needs-based, and well-documented interventions targeting caregivers of various kinds of cardiac patients are needed to develop the field to the benefit of caregivers, patients, and society.

Dyadic relationships between informal caregivers and older adults with chronic heart failure: a systematic review and meta-synthesis

AIMS

To synthesize the qualitative evidence on dyadic relationships between informal caregivers and older adults with chronic heart failure (HF).

METHODS AND RESULTS

A systematic review and meta-synthesis were conducted. Eight databases were searched for English peer-reviewed studies and grey literature published from inception to 27 February 2024. Qualitative and mixed-method studies involving older adults ≥55 years old with chronic HF and discussing patient-caregiver relationships in community settings were included. Data were synthesized using Sandelowski and Barroso's two-step framework. A meta-summary was developed using thematic analysis, and findings were synthesized using the Theory of Dyadic Illness Management. Twenty-four studies from 2008 to 2024 were included (n = 580 participants). The meta-summary consisted of four themes and nine subthemes: (i) Characteristics of dyad relationships, (ii) How both parts of the dyad care for each other, (iii) Chronic HF and dyad relationships, and (iv) Knowledge of managing chronic HF. These were reorganized into the meta-synthesis: dyadic appraisal, dyadic management behaviours, dyadic health, contextual factors affecting dyadic relationships and management behaviours, and illness management as a dyadic phenomenon.

CONCLUSION

Investigating relationship dynamics and their impact on dyads and chronic HF self-care is vital. Where possible, healthcare providers should prioritize dyadic care when caregivers are involved and deliver individualized care to improve patient and caregiver outcomes. Assessing and optimizing dyadic relations, addressing individual perceptions and needs as part of clinical care, and before implementing self-care interventions in research may help ensure that self-care is appropriately tailored and would not be hindered by relationship conflicts.

Management of a Dual Low Sodium and Diabetic Diet by Patient-Caregiver Dyads: A Qualitative Descriptive Study

PURPOSE

The purpose of the study was to explore factors surrounding management of simultaneous dietary recommendations for heart failure and type 2 diabetes among patient-caregiver dyads.

METHODS

Qualitative description was used to explore dyad experiences managing a dual diet. Semi-structured interviews were conducted with patients with a concurrent diagnosis of type 2 diabetes and heart failure and their family caregiver. Each 60-minute interview was conducted virtually. Interviews were audio recorded and transcribed verbatim. Thematic analysis was conducted with coding used for themes at dyadic-and individual levels.

RESULTS

Twelve patient-caregiver dyads (N = 24) were interviewed. The mean age was 57 years (±15 years). Most participants were white (75%); patients were predominantly male, and caregivers were predominantly female (83.3% for both). Dyadic-level themes that emerged included factors that influence simultaneous management of dual diet recommendations. Themes included shared barriers, facilitators, motivators, and strategies for dual diet management. Individual-level themes discussed by patients were barriers and motivators to dual diet management, and caregivers discussed barriers to supporting dual diet management.

CONCLUSIONS

Findings from the study highlight that patients and caregivers often work together and share similar barriers, facilitators, motivators, and strategies for adhering to a dual diet. The results provide insight into chronic disease management at the family level and can guide health care providers' efforts to promote family involvement with dietary recommendations for patients with multiple comorbidities.

Status quo and factors influencing dyadic disease appraisal in chronic heart failure based on latent profile analysis in Northern Sichuan Province, China

PURPOSE

This study explored potential categories of dyadic disease appraisal differences among patients hospitalized with chronic heart failure (CHF) in China and analyzed the main factors influencing these categories.

METHODS

A survey was conducted using various tools and scales, including the Chinese version of the Memorial Heart Failure Symptom Appraisal Scale, Heart failure self-care index scale, Social Support Rating Scale, Zarit burden interview, and Self-rating anxiety scale. The data was collected from patients who were hospitalized with CHF in the cardiology department of one of two tertiary hospitals in Nanchong City, China. The dyadic disease appraisal categories were identified using latent profile analysis (LPA). Multiple logistic regression analysis was also employed to analyze the factors influencing the formation of potential categories of differences in dyadic disease appraisal in CHF patients.

RESULTS

A total of 262 pairs of hospitalized CHF patients and their caregivers participated in this study. The dyadic disease appraisal of CHF patients was potentially categorized as the "negative difference group" (28 individuals, 10.7%) and the "positive or convergence group" (234 persons, 89.3%). The results showed that the factors influencing the categorization of dyadic disease appraisal differences included the patient's social support, disease progression, and Caregivers anxiety level, burden, gender, educational attainment, and age (p < 0.05).

CONCLUSION

The study findings demonstrated heterogeneity between the two groups of CHF patients in the dyadic disease appraisal. Therefore, it is necessary to focus on patients who have a brief duration of illness and limited social support. Specifically, it is important to prioritize support for female caregivers who are 65 years or older, have lower levels of educational attainment, and experience a significant burden and anxiety. Regular implementation of support person-bilateral co-management strategies can effectively reduce differences in how the disease is perceived and enhance the overall well-being of both caregivers and patients.

A predictive model for medication adherence in older adults with heart failure

AIMS

Although many studies have examined the predictors of medication adherence (MA), further empirical research is required to clarify the best model for predicting MA for older adults with heart failure (HF). Thus, we hypothesized a model in which information (knowledge), motivation (social support and depressive symptoms), and behavioural skills (barriers to self-efficacy) would be associated with MA in patients with HF.

METHODS AND RESULTS

Using a cross-sectional survey, 153 adults aged ≥ 65 years taking medication for HF were recruited from a university hospital in Korea. Data were collected based on the information-motivation-behavioural skills (IMB) model constructs and MA. In the hypothesized path model, self-efficacy was directly related to MA (β = -0.335, P = 0.006), whereas social support was indirectly related to MA through self-efficacy (β = -0.078, P = 0.027). Depressive symptoms were directly related to MA (β = 0.359, P = 0.004) and indirectly related to MA through self-efficacy (β = 0.141, P = 0.004). The hypothesized MA model showed a good fit for the data. Knowledge, social support, and depressive symptoms accounted for 44.3% of the variance in self-efficacy (P = 0.004). Left ventricular ejection fraction, knowledge, social support, depressive symptoms, and self-efficacy explained 64.4% of the variance in MA (P = 0.004).

CONCLUSION

These results confirmed the IMB model's suitability for predicting MA in older adults with HF. These findings may guide and inform intervention programmes designed to alleviate depressive symptoms in older adults with HF and enhance their HF knowledge, social support, and self-efficacy, with the ultimate goal of improving their MA.

The feasibility of motivational interviewing on adherence to care practices, emotional intelligence, and dispositional optimism among patients with permanent pacemakers

AIMS

Motivational interviewing (MI) has been recognized as highly effective for treating chronic diseases and various conditions, with encouraging results demonstrating its effectiveness in promoting health behaviour change. The current study was proposed to evaluate the feasibility of MI on adherence to care practices, emotional intelligence (EI), and dispositional optimism among patients with permanent pacemakers.

METHODS AND RESULTS

This study was a parallel arm randomized controlled trial. Seventy clients with permanent pacemakers were randomly allocated to a six-session MI intervention (n = 35) or a waiting list control group (n = 35). A statistically significant improvement in the mean scores of adherence to care practices, EI, and dispositional optimism, along with a significant reduction in pessimism, was registered among the study group compared with the control group.

CONCLUSION

Following the intervention for 1- and 2-month follow-up measurements, there were statistically significant improvements in self-care practice adherence. After 1 month of intervention, there were statistically significant gains in EI and dispositional optimism, but at the 2-month follow-up measurement, this improvement had somewhat lessened. The findings suggest that MI may be a feasible and practical approach for improving adherence to care practices, EI, and dispositional optimism in patients with permanent pacemakers.

Self-care Problems and Management Strategies Experienced by Rural Patient/Caregiver Dyads Living With Heart Failure: A Qualitative Study

BACKGROUND

Rural patients with heart failure (HF) have higher mortality and hospitalization rates compared with their urban counterparts. Although research supports the inclusion of informal caregivers in daily self-care activities, data are limited regarding the problems encountered by rural patient/caregiver dyads living with HF in managing HF in the home and how these problems are managed.

OBJECTIVE

The aim of this study was to identify and describe HF self-care problems experienced by rural dyads in the home and how these problems are managed.

METHODS

Using a descriptive qualitative design, data were collected from rural patient/caregiver dyads living with HF via individual, semistructured, telephone interviews and analyzed using schematic content analysis. Interviews and data analysis occurred concurrently until data saturation was reached.

RESULTS

Thematic data saturation was obtained with 11 dyads. On average, patients were 65.3 (±13.9) years old, and caregivers were 62 (±12.37) years old. Four themes illustrating dyadic HF self-care problems and management strategies emerged: (1) HF self-care components, namely, maintenance, symptom monitoring, and management (diet, exercise, activities, strategies); (2) environment (rural barriers, COVID-19); (3) caregiver contributors (confidence, role); and (4) dyadic contributors (dyadic relationship). Dyads described various self-care problems, with the type of relationship and presence of mutuality influencing the problem-solving process and development of management strategies.

CONCLUSIONS

The identified themes emphasize the self-care problems experienced by rural dyads living with HF and the contributions of both dyad members to effectively manage these challenges. Findings support the need for culturally sensitive, tailored interventions targeting self-care in rural dyads living with HF.

Impact of Caring for Individuals With Heart Failure in the United States: A Systematic Literature Review

BACKGROUND

Given the functional impairments and complex care routines associated with heart failure (HF), patients often rely on the support of informal caregivers. Although the importance of caregivers' roles is widely recognized, the intensity and time required for care duties may negatively impact caregiver health and well-being, potentially precipitating their own need for care.

OBJECTIVE

The aim of this study was to synthesize estimates of economic, clinical, burden, and health-related quality-of-life impact among caregivers of those with HF in the United States.

METHODS

A systematic review was conducted to identify studies reporting estimates of caregiver impact. Abstract and full-text review as well as data extraction were performed according to established guidelines. Patient and caregiver characteristics were summarized, as well as estimates of impact of caring for those with HF.

RESULTS

From 3680 abstracts, 44 studies reporting caregiver burden estimates were included. Mean caregiver age ranged from 41.4 to 71.4 years; caregivers were primarily female (range, 49%-100%) and the patient's spouse/partner (21%-100%). Time spent caregiving (6 studies) ranged from 2 to 52 h/wk, and depression was identified in up to 40% of caregivers (9 studies). Numerous instruments were used to measure burden, which consistently documented the high impact of caregiving.

CONCLUSIONS

This review demonstrates the multifaceted impact of caregiving for patients with HF. Despite limited data, notable findings included the considerable burden to caregivers, variability in time spent caregiving, and frequent experience of depression among caregivers, possibly leading to increased healthcare resource use. Future research is needed to better characterize the caregiving impact in HF, including evaluating the drivers of burden.

Predictors of self-care behaviors in individuals with heart failure in Brazil

OBJECTIVE

To identify the predictors of self-care behaviors in individuals with heart failure.

METHOD

A cross-sectional study including 405 patients with heart failure. Self-care behaviors were assessed by the Self-Care of Heart Failure Index. Sociodemographic and clinical characteristics were investigated as predictors of self-care maintenance, management and confidence through logistic regressions.

RESULTS

The predictors of self-care maintenance were number of children (p<0.01), left ventricular ejection fraction (p<0.01), positive feeling about disease (p=0.03), obesity (p=0.02) and dialytic chronic kidney disease (p<0.01). The predictors of self-care management were having married children (p<0.01) and sleep apnea (p<0.01). The predictors of self-care confidence were family income (p<0.01), number of hospitalizations in the previous 12 months (p=0.01), number of daily medication doses (p<0.01) and sedentarism (p<0.01).

CONCLUSION

Some predictors related to the self-care behaviors were found, so some intensified education and social aid should be aimed at patients with these specific characteristics.

Person with Heart Failure and Care Partner Dyads: Current Knowledge, Challenges, and Future Directions: State-of-the-Art Review

Over the past decade, there has been substantial growth in heart failure (HF) research that focuses on persons with HF and their care partners (family members or other close friends that provide unpaid support) as an interdependent team, or care dyad. In this state-of-the-art review, we use a dyadic lens to identify and summarize current research on HF care dyads, from qualitative studies, to nonexperimental quantitative studies, to randomized controlled trials. Although much work has been done, this literature is younger and less well-developed than care dyad literatures from other conditions (eg, cancer, Alzheimer's disease). We discuss the substantial challenges and limitations in this body of work, with an eye toward addressing common issues that impact rigor. We also look toward future directions, and discuss the promise dyadic research holds for improving patient, care partner, and relationship health.

Motivational Interviewing for Enhancing Self-care in Patients With Heart Failure: Protocol for a Randomized Controlled Trial

BACKGROUND

Heart failure (HF) is characterized by an increasing prevalence, representing a public health problem and a significant cause of morbidity and mortality. Self-care is a cornerstone approach for optimizing therapy for patients with HF. Patients play a crucial role in managing their condition, given that several adverse health outcomes might be avoided with adequate self-care. In this regard, the literature describes motivational interviewing (MI) as highly favorable for treating chronic diseases, with promising results supporting its efficacy in enhancing self-care. Moreover, caregivers' availability constitutes a fundamental supporting factor among the strategies to improve self-care behaviors in people with HF.

OBJECTIVE

The primary study aim is to test the efficacy of a structured program, including scheduled MI interventions, in improving self-care maintenance in the 3-month follow-up from the enrollment. Secondary aims comprehend the assessment of the effectiveness of the above intervention on secondary outcomes (eg, self-care monitoring, quality of life, sleep disturbance) and the corroboration of the superiority of caregivers' participation to the intervention over the program administrated only to individual patients in enhancing self-care behaviors and other outcomes at 3, 6, 9, and 12 months from the enrollment.

METHODS

This study protocol designed a prospective, parallel-arm, open-label, 3-arm, controlled trial. The MI intervention will be administered by nurses trained in HF self-care and MI; the education program will be provided to nurses by an expert psychologist. Analyses will be performed within the framework of intention-to-treat analysis. Comparisons between groups will be based on an alpha of 5% and 2-tailed null hypotheses. In the case of missingness, analyzing the extent of the missingness and identifying underlying mechanisms and patterns will guide imputation methods.

RESULTS

The data collection was started in May 2017. We completed the data collection with the last follow-up in May 2021. We plan to perform data analysis by December 2022. We plan to publish the study results within March 2023.

CONCLUSIONS

MI enhances potential self-care practices in patients with HF and their caregivers. Although MI is effectively largely employed either alone or combined with other treatments and is administered in different settings and ways, face-to-face interventions seem to be more effective. Dyads with higher shared HF knowledge are more efficient in promoting self-care adherence behaviors. Moreover, patients and caregivers may perceive proximity with health care professionals, resulting in a better ability to follow the received health professionals' directions. The scheduled in-person meetings with patients and caregivers will be exploited to administer MI, respecting all the safety regulations for infection containment. The conduction of this study may support changes in clinical practice to include MI to improve self-care for patients with HF.

A State-of-the-Art Review of Teach-Back for Patients and Families With Heart Failure: How Far Have We Come?

BACKGROUND

Heart failure (HF) prevalence has risen for more than a decade. Effective patient and family education strategies for HF are needed on a global scale. One widely used method of education is the teach-back method, where learners are provided information, then their understanding assessed by "teaching it back" to the educator.

PURPOSE

This state-of-the-art review article seeks to examine the evidence focusing on the teach-back method of patient education and patient outcomes. Specifically, this article describes (1) the teach-back process, (2) teach-back's effect on patient outcomes, (3) teach-back in the context of family care partners, and (4) recommendations for future research and practice.

CONCLUSIONS

Study investigators report the use of teach-back, but few describe how teach-back was utilized. Study designs vary widely, with few having a comparison group, making conclusions across studies challenging. The effect of teach-back on patient outcomes is mixed. Some studies showed fewer HF readmissions after education using teach-back, but different times of measurement obscure understanding of longitudinal effects. Heart failure knowledge improved across most studies after teach-back interventions; however, results related to HF self-care were mixed. Despite family care partner involvement in several studies, how they were included in teach-back or the associated effects are unclear.

CLINICAL IMPLICATIONS

Future clinical trials that evaluate the effect of teach-back education on patient outcomes, such as short- and long-term readmission rates, biomarkers, and psychological measures, are needed, as patient education is the foundation for self-care and health-related behaviors.

The effectiveness of self-care management in treating heart failure: A scoping review

Introduction: Heart failure is a common chronic disease associated with increased mortality and rehospitalization rates. Self-care management provided in various ways is one approach to avoiding the need for rehospitalization by lowering recurrence rates. Therefore, this study aims to determine the most effective self-care management interventions for heart failure patients. Design and Methods: The databases Science Direct, Google Scholar, and PubMed were used to conduct literature reviews over ten years. In September 2021, a full-text article search was conducted using the keywords "Self-Care," "Self-Management," "Intervention," "Heart Failure Patients," and "Randomized Control Trial" in PubMed ScienceDirect and Google Scholar databases. The inclusion and exclusion criteria were determined using the PICOS technique. After the screening, 39 articles met the criteria. Results: Self-care management is provided through education programs, training programs, and the utilization of apps and websites to improve its self-care abilities. Conclusions: Therefore, one way to provide self-care management during the COVID-19 pandemic was through the program's website, which is viewed "remotely" and used to track patient progress.  

Associations of perceived and common dyadic coping with self-care in older couples with cardiovascular disease: A dyadic analysis

BACKGROUND

Dyadic engagement of patients and caregivers in self-care is essential for management of heart disease. However, little is known how dyadic coping at individual and partner levels is associated with self-care in couples living with cardiovascular disease.

OBJECTIVE

This study examined whether dyadic coping at self, partner, and common levels was associated with patients' engagement in self-care and spouses' contribution to self-care in older couples living with cardiovascular disease.

METHODS

In this cross-sectional study, 288 older patients and spouses were recruited from outpatient heart clinics in Qazvin, north of Iran. Data were collected using the Dyadic Coping Inventory, the Self-care of Coronary Heart Disease Inventory, and the Caregiver's Contribution to Self-care of Coronary Heart Disease. Dyadic data were analyzed using the actor-partner interdependence model.

RESULTS

The results showed that patients' engagement in self-care maintenance was associated with partner dyadic coping in patients, self and common dyadic coping in spouses. Patients' engagement in self-care monitoring was only associated with self dyadic coping in spouses. Dyadic analysis also showed that self-care confidence in patients was only associated with by partner dyadic coping in spouses.

CONCLUSIONS

This study revealed that self-care was associated with dyadic coping employed by each member of the dyad at self, partner and common levels. Findings of this study suggest that perceived and provided levels of dyadic coping can be employed for maintaining or restoring self-management in older couples living with cardiovascular disease.

The Situation-Specific Theory of Heart Failure Self-care: An Update on the Problem, Person, and Environmental Factors Influencing Heart Failure Self-care

Many studies of heart failure (HF) self-care have been conducted since the last update of the situation-specific theory of HF self-care.

OBJECTIVE

The aim of this study was to describe the manner in which characteristics of the problem, person, and environment interact to influence decisions about self-care made by adults with chronic HF.

METHODS

This study is a theoretical update. Literature on the influence of the problem, person, and environment on HF self-care is summarized.

RESULTS

Consistent with naturalistic decision making, the interaction of the problem, person, and environment creates a situation in which a self-care decision is needed. Problem factors influencing decisions about HF self-care include specific conditions such as cognitive impairment, diabetes mellitus, sleep disorders, depression, and symptoms. Comorbid conditions make HF self-care difficult for a variety of reasons. Person factors influencing HF self-care include age, knowledge, skill, health literacy, attitudes, perceived control, values, social norms, cultural beliefs, habits, motivation, activation, self-efficacy, and coping. Environmental factors include weather, crime, violence, access to the Internet, the built environment, social support, and public policy.

CONCLUSIONS

A robust body of knowledge has accumulated on the person-related factors influencing HF self-care. More research on the contribution of problem-related factors to HF self-care is needed because very few people have only HF and no other chronic conditions. The research on environment-related factors is particularly sparse. Seven new propositions are included in this update. We strongly encourage investigators to consider the interactions of problem, person, and environmental factors affecting self-care decisions in future studies.

Needs and problems related to sociodemographic factors of informal caregiving of people with heart failure: A mixed methods study in three European countries

AIMS

To explore caregivers' needs and problems in three European countries and associate the clusters of caregivers' needs with their sociodemographic characteristics.

DESIGN

A qualitative focused mixed methods design was used.

METHODS

In total, 52 caregivers of heart failure (HF) people were interviewed in three European countries between March 2017 and December 2018. Transcripts were analysed using the seven-phase method of the exploratory multidimensional analysis according to Fraire with Reinert lexical classes findings were organized in dendrograms. Mayring's content analysis was also performed.

RESULTS

Three clusters of caregivers were identified: spouses, adult children and non-family members. Caregivers not only provide HF patients with vital unpaid support for their physical and emotional needs, but they are continually trying to cope with their social isolation and deteriorating health.

CONCLUSIONS

Informal caregiving emerged as a complex process influenced by various sociodemographic factors. Gender, relationship type and economic status are the important factors to be considered planning to develop approaches to address the needs of caregivers serving people with heart failure.

IMPACT

A comprehensive understanding of the nature of informal caregiving of individuals with heart failure, the complexity of the real-world sociodemographic and cultural factors is warranted. The use of the EMDA method gave us the possibility of processing large masses of qualitative data through rapid, complex calculations. In detail, AATD allowed us to study in deep the significant fuzziness of what caregivers expressed and to analyse the content of the entire interviews and to produce global knowledge by using multi-dimensional statistical methods to grasp the fundamental sense of the interviews, beyond the simple words. Three clusters were identified in the samples, including spouses, adult children and non-family members. This study demonstrated that some sociodemographic characteristics could lead to everyday needs. Therefore, these demographic characteristics should be considered in developing targeted interventions. The research was conducted in Europe, but the technique shown can be replicated everywhere. The findings not only impact nursing but can be extended to all those stakeholders who concur with a public health educational mission.

PATIENT OR PUBLIC CONTRIBUTION

Carers were involved in this study after the discharge of their loved ones or at the time of the outpatient visit. They were involved after they had been observed in their dynamics of involvement in caring of the familiars or friends with heart failure.

Disease-related knowledge in people with chronic obstructive pulmonary disease and their informal caregivers: A multilevel modelling analysis

AIMS AND OBJECTIVES

To assess the level of chronic obstructive pulmonary disease (COPD)-related knowledge within patient and informal caregiver dyads, and to identify factors influencing the knowledge level considering the interdependence within the dyads.

BACKGROUND

Patients with COPD and their informal caregivers present poor disease knowledge and different characteristics are associated with their level of knowledge. Disease knowledge and related characteristics have been assessed separately in patients and informal caregivers, without considering possible influence within the dyads.

DESIGN

Cross-sectional study.

METHODS

A convenience sample of dyads was recruited in outpatient and inpatient settings in Central and South Italy. The Bristol COPD Knowledge Questionnaire was used to measure disease knowledge. Sociodemographic, clinical and caregiving characteristics, self-efficacy and depression were measured in patients and caregivers. Multilevel modelling was used to analyse COPD knowledge at the level of the dyad to control for interdependency between patients and informal caregivers. The STROBE guidelines for cross-sectional studies were followed for study reporting.

RESULTS

We recruited 133 dyads. The total level of correct knowledge shared by dyads was 32.89%. Dyads presented higher levels of correct knowledge about disease symptoms, smoking cessation and vaccination, and lower about COPD treatment. Younger patients with greater self-efficacy, who attended pulmonary rehabilitation and were cared for by a spouse/partner with low levels of depression, and informal caregivers who were patients' spouse/partner were more likely to have higher levels of disease-related knowledge.

CONCLUSIONS

Our study advances dyadic research in COPD. Future studies should investigate the effects of shared knowledge and incongruent knowledge (where one member knows more than the other) on patient self-care and caregiver contribution to patient self-care.

RELEVANCE TO CLINICAL PRACTICE

Our study shows what knowledge nurses should provide in educational programmes directed at patients and caregivers, and which dyads have greater knowledge deficits, to whom offer targeted educational interventions.

Review the factors associated with dietary sodium adherence in patients with heart failure from selected research-based literatures

Background

Low-sodium dietary is an important measure to avoid heart failure patient’s body fluid volume overload. There are still more than 50% of heart failure patients who are incapable of complying low-sodium dietary. This study utilized the systematic literature review method, with the purpose to understand the related factors towards the compliance behavior of low-sodium dietary of patients with heart failure.

Methods

This study typed keywords (congestive heart failure, adherence, compliance, low sodium diet, low salt diet, dietary sodium restriction) from computer databases (CINAHL, Cochrane, Medline, ProQuest Nursing Allied Health, PubMed, and ScienceDirect) and according to inclusion criteria were as follows: (1) Research objects were adult patients admitted to HF, (2) Research content were related to sodium diet compliance behavior. (3) Non-intervention research. Exclusion criteria were as follows: (1) participants who was pregnant women, (2) qualitative research, (3) studies on development of tool, (4) poster. Select needed 14 articles that meet the purposes of this study. In addition, the study also collected 4 more studies with the same purpose from the references that were included in the retrieved articles, and finally a total of 18 studies were included in the analysis of this study. Data analysis uses descriptive statistics (percentage, frequency distribution) and content analysis method.

Results

This study use a systematic literature review method, it was found that the results of the studies use nonintervention method, which explored the relevant factors of low-sodium dietary compliance in heart failure patients over the past 20 years, could be summarized in 4 dimensions as social and economic conditions, patient conditions, disease conditions and therapy conditions.

Conclusions

Heart failure patients’ compliance behavior toward low-sodium dietary is multi-dimensional. Therefore, this study recommends when the health care providers evaluating patients’ compliance behavior of low-sodium dietary, it is necessary to consider more different aspects.

A Socioecological Model of Heart Failure Self-Care

Heart failure is a chronic, progressively worsening condition afflicting more than 64 million individuals worldwide. Heart failure outcomes are influenced by self-care, a naturalistic patient-centered decision-making process. The situation-specific theory of heart failure self-care addresses how this decision-making process determines actions and outcomes. However, little is known about the impact of socioecological determinants of health on heart failure self-care. A theoretical synthesis could advance the situation-specific theory of heart failure self-care through the inclusion of socioecological determinants of health. Thus, socioecological determinants of health related to heart failure self-care can be better explored, understood, and overcome through research and health promotion.

Heart Failure Care: Testing Dyadic Dynamics Using the Actor-Partner Interdependence Model (APIM)-A Scoping Review

Self-care behaviors are essential for the effective treatment of heart failure (HF), and poor self-care may lead to adverse clinical events in patients with HF. A growing body of literature addresses the need to analyze the characteristics of both patient and caregiver since they are in mutual, long-term interaction, and their reactions to events are dependent on each other. One of the most common approaches for analyzing data on HF self-care dyads is the Actor-Partner Interdependence Model (APIM). The purpose of this study was to conduct a scoping review to answer the following question: what did we learn from HF dyadic studies based on the APIM approach? Medline, Academic Search Ultimate, and CINAHL Complete databases were searched, using the terms "dyad," "dyadic," and "heart failure," for studies published between 2009 and April 2021. Fifteen studies were reviewed from a pool of 106 papers. Studies using the APIM approach revealed interrelated patient and caregiver characteristics that influence self-care and explain many complex dyadic behaviors. Our analysis provided evidence that (1) APIM is a useful analytical approach; (2) a family-oriented approach can improve the functioning of a patient with HF; and (3) social support from caregivers significantly enhances patients' adaptation to illness.

Literacy critical to heart failure management: a scoping review

Heart failure is a complex clinical syndrome most commonly encountered among older adults. This complex clinical syndrome is associated with poor health outcomes such as frequent admissions and mortality. These adverse outcomes are commonly associated with poor self-care and lower health literacy. Literacy is a combination of knowledge and skills and often reflected by appropriate interaction with the community, while health literacy is the cognitive and social skills reflected by accessing and comprehending health information and making appropriate health decisions. These decisions are common and challenging to patients with heart failure. Poor outcomes are said to be reduced by adequate self-care, which is associated with health literacy among heart failure patients. Better self-care was also shown to be associated with self-efficacy and self-confidence that were in turn associated with health literacy. Hence, enhancing health literacy among patient with heart failure is critical to enable them to increase control over their disease by better understanding and participating in health care, while being empowered to take part in designing health care services and even tailoring research to serve their needs and consequently improve outcome at the individual and community level. In clinical practice, assessing health literacy, measuring health literacy, and identifying patients at risk of low nutrition literacy is important to enhance health literacy and health outcomes. Hence, developing reliable and valid methods and tools for assessment and developing tailored and targeted interventions is of critical importance.

The of effect of partnership-based education on adherence to the treatment plans in open heart surgery

BACKGROUND

Adherence to the treatment plans is one of the most effective conducts to prevent and reduce postoperative side effects. Partnership-based education is one of the most efficient ways to shape health behaviors. The aim of the present study was to determine the effect of partnership-based education on adherence to the treatment plans in open heart surgery.

MATERIALS AND METHODS

This quasi-experimental study was conducted in 2019-2020 on the patients undergoing open heart surgery in Tehran (Capital of Iran). Sampling was done in one educational hospital. A total of 86 patients and their caregivers participated in the study. Sampling was done nonrandomly by tossing a coin, and patients were allocated into the odd week in the intervention group and the even week in the control group (n = 43 in each group), and data were collected before and after intervention using the Treatment Adherence Questionnaire concerning dietary, physical activity, and medication aspects. The educational intervention was carried out after the pretest analysis in five 20-45 min sessions (two individual and three group educations). Data were analyzed with Chi-square, independent t-test, and paired t-test using SPSS 19 at a significance level of P < 0.05.

RESULTS

Patients and caregivers in both groups did not have a significant difference in terms of demographic variables (P > 0. 05). In addition, there was no significant difference in the mean of dietary, physical activity, and medication plans before the intervention in both groups; however, after the intervention, the mean of the three aspects in the intervention group was significantly higher than that of control (P < 0.001).

CONCLUSION

Implementing partnership-based education with participation of patients and caregivers is influential in improving patients' adherence to the treatment plans and it is recommended as a clinical dynamic educational strategy.

Associations between self-efficacy, distress and anxiety in cancer patient-relative dyads visiting psychosocial cancer support services: Using actor-partner interdependence modelling

BACKGROUND

Patients with cancer and their relatives often suffer from psychosocial burdens following a cancer diagnosis. Psychosocial cancer support services offer support for cancer patients and their relatives. Only a few studies have focused on associations of psychological factors within patient-relative dyads. This study aims to assess associations between the patients' or relatives' self-efficacy and their levels of distress and anxiety who seek help together at psychosocial cancer support centres.

METHODS

Participants were recruited at two psychosocial cancer support centres in a major city in Germany. Patients with cancer and their relatives seeking support together received the questionnaire before their first support session. Self-efficacy was assessed with the Pearlin sense of mastery scale, distress with the distress thermometer and anxiety with the General Anxiety Disorder questionnaire (GAD-7). For the analysis, the actor-partner interdependence model was applied.

RESULTS

The data analysis was based on 41 patient-relative dyads (patients: 39% women, mean age 53.5; relatives: 66% women, mean age 52.16). A significant actor effect from self-efficacy to distress was found for patients (r = -0.47) but not for relatives (r = -0.15). Partner effects from self-efficacy to distress were not significant (r = -0.03, r = -0.001). The actor effect from self-efficacy to anxiety for patients (r = -0.61) as well as relatives was significant (r = -0.62), whereas the partner effect was significant for patients (r = 0.16) but not for relatives (r = -0.46).

CONCLUSION

The results suggest that patients' and relatives' self-efficacy is associated with their distress and anxiety. Partner effects were visible for patients' self-efficacy and relatives' anxiety. These findings suggest that self-efficacy is an important factor for the psychological well-being of patients and relatives and that it may additionally be associated with the partners' well-being. Longitudinal research with larger samples is needed to support the findings.

Validity and Reliability of the Caregiver Contribution to Self-Care of Heart Failure Index Version 2

BACKGROUND

Lay caregivers are important in contributing to self-care of patients with heart failure (HF). The Caregiver Contributions to Self-Care of Heart Failure Index (CC-SCHFI) measures these contributions, but after developing the Situation-Specific Theory of Caregiver Contributions to Heart Failure Self-Care, the CC-SCHFI needed updating to reflect the theory.

OBJECTIVE

The aim of this study was to test the psychometric characteristics of the CC-SCHFI 2 that measures caregiver contributions (CC) to HF self-care with 3 scales: CC to self-care maintenance, CC to symptom perception, and CC to self-care management.

METHODS

This is a cross-sectional study. We tested the CC-SCHFI 2 with confirmatory factor analysis, internal consistency, item-total correlations, and test-retest reliability. With the CC-SCHFI 2, we also administered the Self-Care of Heart Failure Index v.7.2 to patients and the Caregiver Contribution to Heart Failure Self-Care Scale to caregivers to assess concurrent validity.

RESULTS

A sample of 277 caregivers was enrolled (mean [SD] age, 52.7 [14.9] years; 70.4% female). In confirmatory factor analysis, each CC-SCHFI 2 scale had supportive fit indices: comparative fit index ranged between 0.94 and 0.95, and root mean square error of approximation ranged between 0.05 and 0.07. Internal consistency of the 3 scales was evident with a Cronbach α between .81 and .83 and a global reliability index between 0.79 and 0.86. Item-total correlations were all greater than 0.30. In concurrent validity testing, there were significant correlations between the CC-SCHFI 2 and the Self-Care of Heart Failure Index v.7.2 and the Caregiver Contribution to Heart Failure Self-Care Scale. Test-retest reliability showed intraclass correlation coefficients between 0.72 and 0.91.

CONCLUSIONS

Testing of the CC-SCHFI 2 supported validity and reliability, indicating that the instrument can be used in clinical practice and research to evaluate CC to the self-care of patients with HF.

Experiences of and factors associated with dietary sodium adherence in heart failure from patients' and their caregivers' perspectives: A qualitative study

This study explored experiences of dietary sodium adherence among patients with heart failure and their caregivers. Qualitative data were collected from 22 patients and 18 caregivers using an interview guide and were analyzed using content analysis. Four themes were (1) lack of adherence to low-sodium diet, (2) several barriers to dietary sodium adherence, (3) a few facilitators of dietary sodium adherence, and (4) distorted perceptions of dietary education from healthcare providers. The majority of patients had poor dietary sodium adherence. Distorted perceptions, insufficient knowledge, disadvantages of dietary sodium adherence, and lack of family support were barriers to dietary sodium adherence, and family support was a facilitator. The majority of patients received dietary education from their healthcare providers but had little knowledge about the detailed content and the connection to heart failure management. More effective interventions reflecting patients' and caregivers' dietary experiences need to be developed and delivered.

The influence of dyadic congruence and satisfaction with dyadic type on patient self-care in heart failure

BACKGROUND

Chronic illness management is increasingly carried out at home by individuals and their informal caregivers (dyads). Although synergistic in concept, the nuances of dyadic congruence in caring for patients with heart failure are largely unexamined.

AIMS

The purpose of this study was to examine the role of dyadic-type congruence on patient self-care (maintenance, symptom perception, and management) while controlling for actor and partner effects.

METHODS

This secondary data analysis of 277 dyads consisted of a series of multilevel models to examine the impact of dyadic congruence on a patient's self-care maintenance, symptom perception, and self-care management. Patient-level and caregiver-level data were input into each model simultaneously to account differential appraisals of factors related to the dyad.

RESULTS

Bivariate analyses yielded dyad congruence which was associated with better patient self-care maintenance, symptom perception and management. However, after multilevel models were constructed, dyad congruence was found to be a significant predictor of patient's symptom perception scores, but not self-care maintenance or management scores. Caregiver's satisfaction with the dyad was differentially and significantly associated with self-care - it was inversely associated with patient self-care maintenance and positively associated with patient self-care management.

CONCLUSION

This is the first study, to our knowledge, reporting that congruence in heart failure dyads is associated with better patient symptom perception and this advances our prior hypothesis that dyad typologies could be used to predict patient self-care performance. Since symptom perception is the key to preventing heart failure exacerbation, screening heart failure patient and caregiver dyads for congruence is important in clinical settings.

Dietary Sodium Restriction for Heart Failure: A Systematic Review of Intervention Outcomes and Behavioral Determinants

The 1500 mg/d dietary sodium restriction commonly recommended for patients with heart failure has recently been questioned. Poor adherence to sodium-restricted diets makes assessing the efficacy of sodium restriction challenging. Therefore, successful behavioral interventions are needed. We reviewed sodium restriction trials and descriptive studies of sodium restriction to: 1) determine if sodium restriction was achieved in interventions among heart failure patients; and 2) characterize predictors of successful dietary sodium restriction. Among 638 identified studies, 10 intervention trials, and 25 descriptive studies met inclusion criteria. We used content analysis to extract information about sodium restriction and behavioral determinants of sodium restriction. Dietary sodium was reduced in 7 trials; none achieved 1500 mg/d (range 1938-4564 mg/d). The interventions implemented in the interventional trials emphasized knowledge, skills, and self-regulation strategies, but few addressed the determinants correlated with successful sodium restriction in the descriptive studies (eg, social/cultural norms, social support, taste preferences, food access, self-efficacy). Findings suggest that incorporating determinants predictive of successful dietary sodium restriction may improve the success of interventional trials. Without effective interventions to deploy in trials, the safety and efficacy of sodium restriction remains unknown.

An Integrative Review of the Symptom Perception Process in Heart Failure

BACKGROUND

Accurate symptom perception is a fundamentally essential component of self-care for patients with heart failure (HF) so they can make appropriate decisions about their symptoms.

OBJECTIVE

The purpose of this integrative review was to describe the pathways of the symptom perception process and its contributing factors in patients with HF.

METHODS

A comprehensive literature search was conducted using PubMed, EMBASE, and PsycINFO databases to identify studies describing the symptom perception process (symptom detection, comprehension, and response) in adult patients with HF.

RESULTS

Two pathways of the symptom perception process were identified from 42 articles: ideal and undesirable pathways. Patients in the ideal symptom perception pathway had a comprehensive understanding of HF and a firm belief in the importance of self-care, were vigilant, and possessed good decision-making skills. They also were able to successfully use their experiences for future care. However, patients in the undesirable symptom perception pathway had a limited understanding of HF with poor symptom monitoring skills and inaccurate judgments about symptoms. Diverse factors contributing to the symptom perception process were identified (eg, levels of understandings of HF and social support).

CONCLUSION

Our review indicated that symptom perception was likely to diversify the pathway of HF management. A variety of contributing factors to the symptom perception process were found to be intertwined. The findings of our review can inform the development of best patient education practice, although further research needs to be conducted to understand why and how patients can follow the most appropriate path from their past experiences.

Knowledge about heart failure and self-care persists following outpatient programme- a prospective cohort study from the Faroe Islands

Objectives: Longer life expectancies imply increased prevalence of heart failure. Blittle is known about the maintenance of disease specific knowledge following patient education. Our aim was to investigate if self-care and heart failure knowledge persists at 9 month follow up among patients with heart failure after an outpatient programme in the Faroe Islands.

Methods: A prospective cohort study with patients recently diagnosed with heart failure were recruited and evaluated by questionnaire at baseline, after 3 and 9 months using The European Heart Failure Self-Care Behaviour Scale and the Dutch Heart Failure Knowledge Scale. Clinical and demographic information was collected.

Results: Seven (15%) women and 40 (85%) men with heart failure and NYHA > 2 were included. There was an overall improvement in patients’ self-care from baseline 25 (8) to 3 months 15 (5) and to 9 months (16 (45); both p < 0.001). Mean knowledge score 10 (3) improved to 13 (2) at 3 months and 12 (2) at 9 months (both p < 0.001).

Conclusions: Disease specific patient education is applicable to heart failure patients, which can produce persistent improvements in self-care and knowledge after multidisciplinary outpatient programme.

Practice Implications: Multidisciplinary outpatient programmes are beneficial for patients with heart failure and alters disease specific knowledge and self-care.

Hospitalized patients with heart failure: the impact of anxiety, fatigue, and therapy adherence on quality of life

Introduction

Heart failure (HF) is a major global health problem associated with increased morbidity and mortality and reduced quality of life (QoL). The aim of the study was to assess the impact of anxiety, fatigue and adherence to therapeutic guidelines on HF patients' QoL.

Material and methods

A hundred and twenty hospitalized HF patients were enrolled in the study. Data collection was performed by completion of the Minnesota Living With Heart Failure Questionnaire (MLHFQ), the Greek version of the Modified Fatigue Impact Scale (MFIS-Greek), the Zung Self-Rating Anxiety Scale (SAS) and a questionnaire that measured adherence to therapeutic guidelines.

Results

Data analysis showed moderate levels of anxiety and high levels of adherence to therapeutic guidelines as well as moderate to large effects of HF on patients' fatigue and QoL. A statistically significant positive linear association was observed between anxiety and QoL (rho > 0.6) as well as fatigue and QoL (rho > 0.3). An increase in the anxiety or fatigue score indicated an increase also in the QoL score, meaning that the more anxiety and fatigue a patient felt the worse the QoL also was. Moreover, a statistically significant negative linear association was observed between adherence to therapeutic guidelines and QoL (rho < -0.2). An increase in adherence score indicated a decrease in QoL score, meaning that the more adherent a patient was the better was the QoL.

Conclusions

The present findings suggest that QoL may be improved when adherence to therapy is increased and fatigue and anxiety are alleviated.

Identifying subgroups: Part 1: Patterns among cross-sectional data

Non-experimental designs are common in nursing and allied health research wherein study participants often represent more than a single population or interest. Hence, methods used to identify subgroups and explore heterogeneity have become popular. Latent class mixture modeling is a versatile and person-centered analytic strategy that allows us to study questions about subgroups within samples. In this article, a worked example of latent class mixture modeling is presented to help expose researchers to the nuances of this analytic strategy.

Predictors of rehospitalization for community-dwelling older adults with chronic heart failure: A structural equation model

AIMS

To examine the effects of health literacy, activities of daily living, frailty and self-care on rehospitalization for older adults with chronic heart failure using a structural equation model.

DESIGN

This was a cross-sectional study.

METHODS

Two hundred and seventy-one older patients with chronic heart failure were recruited using a convenience sampling method from three community healthcare centres in Guangzhou, Southern China. The data were collected using a questionnaire survey between April 2018 and October 2018 by three research assistants.

FINDINGS

The proposed model revealed a good fit to the data (χ² /d.f. = 2.39, root mean square error of approximation = 0.06, goodness of fit index = 0.93, comparative fit index = 0.91, normed fit index = 0.91). Health literacy (β = 0.21), activities of daily living (β = 0.43), frailty (β = 0.29) and self-care (β = 0.40) directly affected the rehospitalization of older patients with chronic heart failure. Health literacy (β = 0.19), activities of daily living (β = 0.36) and frailty (β = 0.33) indirectly affected rehospitalization through self-care. Frailty (β = 0.16) indirectly affected rehospitalization by activities of daily living. Activities of daily living had the highest direct and total effects on rehospitalization; the effect values were 0.43 and 0.57, respectively.

CONCLUSION

Community-dwelling older adults with chronic heart failure who had limited health literacy, frailty, declined activities of daily living and lower self-care were eligible for rehospitalization. Self-care and activities of daily living were considered mediators between rehospitalization and its predictors. A future longitudinal study is required to validate the results.

IMPACT

Tailored and targeted measures aiming to enhance self-care and activities of daily living have been developed for older patients with chronic heart failure because they are not only predictors but also mediators. Assessment of health literacy level of this population is the first step before developing health education. Frailty of patients with chronic heart failure should be reduced to a minimum level.

Evaluating emotional distress and health-related quality of life in patients with heart failure and their family caregivers: Testing dyadic dynamics using the Actor-Partner Interdependence Model

PURPOSE

1) To compare levels of emotional symptoms and health-related quality of life between patients with heart failure and their family caregivers; and 2) to examine whether patients' and caregivers' emotional symptoms were associated with their own, as well as their partner's health-related quality of life.

METHOD

In this cross-sectional study, 41 patients-caregiver dyads (78% male patients, aged 68.6 years; and 83% female caregivers, aged 65.8 years) completed all nine dimensions of the Brief Symptom Inventory and the Minnesota Living with Heart failure Questionnaire. Dyadic data were analysed for 6 sub-scales of the Brief Symptom Inventory, using the Actor-Partner Interdependence Model.

RESULTS

There were no statistically significant differences in emotional symptoms and health-related quality of life between patients with heart failure and their caregivers. Patients' and caregivers' emotional symptoms were associated with their own health-related quality of life. Caregivers' anxiety, phobic anxiety, obsession-compulsion, depression and hostility negatively influenced their partner's (i.e. the patient's) health-related quality of life. There were no partner effects of patients' emotional symptoms on the health-related quality of life of caregivers.

CONCLUSIONS

The results of this study suggest that patients may be particularly vulnerable to the emotional distress, i.e. thoughts, impulses and actions of their caregivers. It may be possible to improve patients' health-related quality of life by targeting specific detrimental emotional symptoms of caregivers.

Pediatric Heart Transplantation: Transitioning to Adult Care (TRANSIT): Feasibility of a Pilot Randomized Controlled Trial

BACKGROUND

Young-adult heart transplant recipients transferring to adult care are at risk for poor health outcomes. We conducted a pilot randomized controlled trial to determine the feasibility of and to test a transition intervention for young adults who underwent heart transplantation as children and then transferred to adult care.

METHODS

Participants were randomized to the transition intervention (4 months long, focused on heart-transplant knowledge, self-care, self-advocacy, and social support) or usual care. Self-report questionnaires and medical records data were collected at baseline and 3 and 6 months after the initial adult clinic visit. Longitudinal analyses comparing outcomes over time were performed using generalized estimating equations and linear mixed models.

RESULTS

Transfer to adult care was successful and feasible (ie, excellent participation rates). The average patient standard deviation of mean tacrolimus levels was similar over time in both study arms and < 2.5, indicating adequate adherence. There were no between-group or within-group differences in percentage of tacrolimus bioassays within target range (> 50%). Average overall adherence to treatment was similarly good in both groups. Rates of appointment keeping through 6 months after transfer declined over time in both groups.

CONCLUSIONS

The feasibility of the study was demonstrated. Our transition intervention did not improve outcomes.
