Patterns, relevance and predictors of heart failure dyadic symptom appraisal

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.

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.

Effects of the family customised online FOCUS programme on patients with heart failure and their informal caregivers: a multicentre, single-blind, randomised clinical trial

Background

Living with heart failure can severely affect the physical and mental health of patients with heart failure and their caregivers. Available dyadic self-care interventions for heart failure are scarce, especially in China. We aimed to develop and test the family FOCUS programme.

Methods

This single-blind, randomised, controlled study was conducted at four hospitals in Tianjin, China. Patients with heart failure (aged at least 18 years) and their caregiver (dyads) were randomly assigned to either the intervention (n = 71) or control (n = 71) group in a 1:1 ratio. The primary outcomes of this study were patient self-care, with three specific dimensions (self-care maintenance, symptom perception, and self-care management), and caregiver contribution to self-care, mirroring these three dimensions. The outcomes were assessed at baseline (T0) and 4 (T1), 12 (T2), and 24 (T3) weeks post-discharge, respectively. This work is registered on ChiCTR, ChiCTR2100053168.

Findings

Between May 20, 2022, and September 30, 2022, 142 dyads with heart failure were enrolled. The intervention group exhibited dropout rates of 6%, 8.5%, and 18.3% at 4, 12, and 24 weeks after discharge, while the control group showed 9.9%, 12.3%, and 25.4%. Compared with the control group, patients in the intervention group reported improved self-care maintenance (β: 8.5, 95% CI: 0.7, 16.4) and management (β: 7.2, 95% CI: 0.1, 14.3) at T1, as well as improved symptom perception at both T1 (β: 9.7, 95% CI: 1.5, 17.9) and T2 (β: 9.6, 95% CI: 0.6, 18.6). Furthermore, caregiver contributions to self-care maintenance, self-care management, and symptom perception (excluding T3) exhibited significant improvements at all timepoints.

Interpretation

Although the significant improvements in patients' self-care were not long-lasting, this study suggested that the family FOCUS programme consistently enhanced caregivers' contributions to self-care. Future work could explore the effect of the family FOCUS programme on families with multiple chronic conditions.

Empowered But Isolated: A Qualitative Research on Experiences of Family Caregivers of Patients With Acute Heart Failure in China

BACKGROUND

Family caregivers play crucial roles in the self-management of patients with heart failure (HF). However, little is known about caregiving experiences of Chinese family caregivers during acute HF.

OBJECTIVE

The aim of this study was to describe Chinese family caregivers' experiences in symptom management and care-seeking during acute HF.

METHODS

This is an exploratory, qualitative study using the Consolidated Criteria for Reporting Qualitative Research guidelines. Data were collected through semistructured interviews and analyzed with thematic analysis.

FINDINGS

A total of 21 family caregivers of patients with acute HF were enrolled in this study. "Empowered but isolated" was identified as the overarching theme during data analysis, including 3 themes and 6 subthemes: (1) "Responsible symptom managers: leading the home-based symptom management," including 2 subthemes, "Proxy in symptom management" and "Only knowing the surface, instead of the truth"; (2) "Powerless anchors: care-seeking is a torturous journey," including 2 subthemes, "Facing discrepancies in care-seeking" and "Seeing a doctor is the last choice"; (3) "Carrying the weight forward: responsibility combing with emotional burnout," including 2 subthemes, "Living on tenterhooks" and "Submitting to fate."

CONCLUSIONS

In this study, we described Chinese family caregivers' experiences in symptom management and care-seeking during acute HF. Although empowered as proxy, they were also isolated bearing a great burden, receiving insufficient support from patients, family, and the medical system.

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.

Taking Care of Us© (TCU) study protocol: feasibility and acceptability of a dyadic intervention for couples living with heart failure

BACKGROUND

There are more than 1 million hospital admissions and 3 million emergency visits for heart failure in the USA annually. Although spouse/partners make substantial contributions to the management of heart failure and experience poor health and high levels of care strain, they are rarely the focus of heart failure interventions. This protocol describes a pilot randomized controlled trial that tests the feasibility, acceptability, and preliminary change in outcomes of a seven-session couple-based intervention called Taking Care of Us© (TCU). The TCU© intervention is grounded in the theory of dyadic illness management and was developed to promote collaborative illness management and better physical and mental health of adults with heart failure and their partners.

METHODS

A two-arm randomized controlled trial will be conducted. Eligible adults with heart failure and their co-residing spouse/partner will be recruited from a clinical site in the USA and community/social media outreach and randomized to either the TCU© intervention or to a control condition (SUPPORT©) that offers education around heart failure management. The target sample is 60 couples (30 per arm). TCU© couples will receive seven sessions over 2 months via Zoom; SUPPORT© couples will receive three sessions over 2 months via Zoom. All participants will complete self-report measures at baseline (T1), post-treatment (T2), and 3 months post-treatment (T3). Acceptability and feasibility of the intervention will be examined using both closed-ended and open-ended questions as well as enrollment, retention, completion, and satisfaction metrics. Preliminary exploration of change in outcomes of TCU© on dyadic health, dyadic appraisal, and collaborative management will also be conducted.

DISCUSSION

Theoretically driven, evidence-based dyadic interventions are needed to optimize the health of both members of the couple living with heart failure. Results from this study will provide important information about recruitment and retention and benefits and drawbacks of the TCU© program to directly inform any needed refinements of the program and decision to move to a main trial.

Effectiveness of a family customised online FOCUS programme aimed on building resiliency in dyad relationship to support dyadic illness management in persons with heart failure and their informal caregiver: a randomised clinical trial protocol

INTRODUCTION

Living with heart failure (HF), is a shared journey and arduous work for patients and their informal family caregivers. Given the key role and limited evidence of dyad illness management in improving dyad health in the context of HF, we developed a customisable, relationship focused, family online dynamic disease management programme-FOCUS programme-to improve dyad health for HF patients and their informal caregivers in China.

METHODS AND ANALYSIS

Based on the Theory of Dyadic Illness Management and the Systemic Transactional Model of Stress and Coping, the family customised online FOCUS programme has five modules: (1) family participatory; (2) open communication; (3) coping effectiveness; (4) uncertainty reduction and 5) shared dyad life stories. HF family dyads will be recruited in the cardiology wards of four university-affiliated hospitals in China. The dyads (N=142) will be randomly allocated to the intervention group that will receive the family customised online FOCUS programme, and the attention control group that will not receive elements of the FOCUS programme. Dyadic coping, HF somatic perception, self-care, anxiety and depression for patients and family caregivers and all-cause mortality and hospital admission for patients will be measured at baseline, 4 weeks (after the discharge, T1), 12 weeks (after the discharge, T2) and 24 weeks (after the discharge, T3). Statistical analysis will be performed using SPSS V. 22.0 software.

ETHICS AND DISSEMINATION

The study protocol was approved by the ethics committees of Tianjin Medical University (Reference number TMUHEC2019002) that covers all the centres enrolled in this study. The findings of this study will be published in scientific journals and will be presented at scientific conferences.

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.

Patterns and predictors of dyspnoea following left ventricular assist device implantation

AIMS

Dyspnoea is a common symptom of heart failure (HF) that often prompts patients to seek treatment. Implantation of a left ventricular assist device (LVAD) has been associated with reduced dyspnoea but it is unclear if all patients experience similar improvements in dyspnoea over time following LVAD implantation. Our aim was to identify distinct trajectories of dyspnoea symptoms over time following LVAD implantation and predictors of dyspnoea trajectory. We hypothesized that at least two, distinct trajectories of dyspnoea would be observed following LVAD implantation.

METHODS AND RESULTS

This was a secondary analysis of data from the Profiling Biobehavioral Responses to Mechanical Support in Advanced Heart Failure study. In the parent study, sociodemographic and clinical data were collected prior to LVAD implantation and at 1, 3, and 6 months following LVAD implantation from a sample (n = 101) of patients with advanced HF. Latent growth mixture modelling was performed to identify distinct trajectories of dyspnoea symptoms. Backwards stepwise logistic regression was used to identify predictors of dyspnoea trajectory. Two, distinct trajectories of dyspnoea symptoms were identified: sustained improvement and unsustained improvement. Participants who experienced sustained improvement (86.7% of sample) demonstrated large, significant improvement in dyspnoea from pre-implantation to 3 months post-implant followed by smaller, non-significant improvement from 3 to 6 months. Participants who experienced unsustained improvement (13.3% of sample) demonstrated initial improvement from pre-implantation to 3 months post-implantation followed by worsening of dyspnoea from 3 to 6 months. Greater depressive symptoms at baseline and living alone were significant predictors of unsustained improvement.

CONCLUSION

Patients experience different patterns of dyspnoea over time following LVAD implantation. Clinicians should inquire about living arrangements and depressive symptoms at each visit to determine risk of unsustained improvement in dyspnoea.

Caregiver subjective and physiological markers of stress and patient heart failure severity in family care dyads

Greater family caregiver exposure to uncontrolled patient symptoms is predictive of greater caregiver psychological and physiological stress in dementia and other chronic illnesses, but these phenomena have not been well-studied in heart failure (HF) - a disease with high symptom burden. The purpose of this study was to test the hypothesis that worse patient functional status (as reflected by increasing HF symptoms) would be associated with elevated psychological and physiological stress for the caregiver. This was a secondary analysis of data from 125 HF caregivers in the Caregiver Opportunities for Optimizing Lifestyle (COOL) study. Psychological stress was measured on four dimensions: care-related strain/burden (Oberst Caregiving Burden Scale), depression (Center for Epidemiological Studies Depression Scale), anxiety (State-Trait Anxiety Index), and general stress (Perceived Stress Scale). Physiological stress was measured by markers of HPA axis function (elevated cortisol awakening response [CAR]), endothelial dysfunction (increased PAI-1), and inflammation (increased IL-6, hsCRP). HF patient functional status was quantified by caregiver assessment of New York Heart Association (NYHA) Class. Generalized linear models were used to test associations between patient NYHA Class and stress (one model per indicator). NYHA Class (ordinal) was backwards difference coded in each model to examine caregiver stress in relation to increasing levels of HF severity. Caregivers were mostly female and in their mid-fifties, with a slight majority of the sample being African American and the patient's spouse. Overall, patient functional status was associated with greater caregiver psychological and physiological stress. In terms of psychological stress, higher NYHA Class was significantly associated with greater caregiver anxiety and general stress, but not with caregiver burden or depression. In terms of physiological stress, higher NYHA Class was associated with elevated markers in all models (elevated CAR and higher IL-6, hsCRP, and PAI-1). Across models, most associations between NYHA Class and stress were present at relatively early stages of functional limitation (i.e. Class II), while others emerged when functional limitations became more severe. To inform timing and mechanisms for much-needed caregiver interventions, research is needed to determine which aspects of HF symptomatology are most stressful for caregivers across the HF trajectory.

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.

A pilot randomized clinical trial of a teamwork intervention for heart failure care dyads

BACKGROUND

Dyadic heart failure (HF) management can improve outcomes for patients and caregivers and can be enhanced through eHealth interventions.

OBJECTIVE

To evaluate the feasibility, acceptability, and preliminary efficacy of an eHealth dyadic teamwork intervention, compared to an attention control condition.

METHODS

We recruited 29 HF patient-caregiver dyads from inpatient units and randomized dyads to an intervention or a control group. We calculated enrollment and retention rates, described acceptability using interview and questionnaire data, and computed intervention effect sizes.

RESULTS

37% of eligible dyads agreed to participate and 93% of randomized participants completed follow-up questionnaires. Participants found both study conditions to be acceptable. Between-group effect sizes suggested that the intervention led to improvements in relationship quality, self-efficacy, and quality of life for patients and caregivers.

CONCLUSIONS

Dyadic recruitment from acute care settings is challenging. Findings provide initial evidence that our intervention can contribute to better health outcomes for HF dyads.

Patterns of Dyadic Appraisal of Decision-Making Involvement of African American Persons Living With Dementia

BACKGROUND AND OBJECTIVES

Greater everyday decision-making involvement by persons living with dementia (PLWD) and congruent appraisal between PLWDs and their caregivers have been associated with a better quality of life (QOL) for both members of the dyad. However, no study has examined the association between the appraisals of everyday decision-making involvement of PLWDs and their QOL among African Americans.

RESEARCH DESIGN AND METHODS

A secondary analysis of cross-sectional data from 62 African American dementia dyads was conducted. Multilevel and latent class mixture modeling was used to characterize dyadic appraisal of the decision-making involvement of African American PLWDs and identify distinct patterns thereof.

RESULTS

Three distinct patterns were observed. "Incongruent, PLWD Low Involvement" labeled 19.4% of the sample, 53.2% were labeled "Incongruent, PLWD Moderate Involvement," and 27.4% were labeled "Congruent, PLWD High Involvement." The Congruent, PLWD High Involvement pattern consisted of PLWDs who were significantly younger and had significantly less cognitive impairment than PLWDs in the other patterns. In the Incongruent, PLWD Moderate Involvement pattern, PLWDs had significantly better QOL than PLWDs in the Incongruent, PLWD Low Involvement pattern, but QOL did not significantly differ from PLWDs in the Congruent, PLWD High Involvement pattern.

DISCUSSION AND IMPLICATIONS

There is a need to tailor strategies to optimize QOL in African American dementia dyads. While increasing everyday decision-making involvement for PLWDs in the Incongruent, PLWD Low Involvement pattern is an important goal, other strategies may be needed to improve the QOL of PLWDs in the remaining patterns.

The role of symptom appraisal, concealment and social support in optimizing dyadic mental health in heart failure

Objectives: Heart failure patients and their family care partners experience poor mental health, yet the majority of the research focuses on patients and care partners separately. Guided by the Theory of Dyadic Illness Management, the purpose of the current study was to identify distinct patterns of dyadic mental health in heart failure and identify the individual, dyadic and familial factors associated with group membership.Method: Fifty nine heart failure community-dwelling patients and their spouse care partners were recruited from an outpatient heart failure clinic. Mental health was operationalized by depressive symptoms, measured with the Patient Health Questionnaire-9 (PHQ-9) measure of depression. Distinct groups of dyadic mental health were determined by categorizing depression scores within dyads.Results: Three groups of dyadic mental health were identified: an optimal dyadic mental health group (31%), a poor dyadic mental health group (32%) and an incongruent dyadic mental health group (37%). Patient age, patient fatigue, patient concealment, incongruent dyadic appraisal of pain interference and social/familial support were significantly associated with group membership.Conclusion: Findings underscore the salience of a dyadic approach to health and the clinical relevance of identifying patterns of dyadic mental health so we may determine those most in need of intervention.

Patterns of Heart Failure Dyadic Illness Management: The Important Role of Gender

BACKGROUND

The ways in which patients with heart failure (HF) and their care partners work together to manage HF are often overlooked.

OBJECTIVE

The aim of this study was to identify and compare different patterns of HF dyadic illness management.

METHODS

This was a secondary analysis of data on HF dyads. Heart failure management was measured using patient and care partner versions of the Self-Care of HF Index and European HF Self-care Behavior Scale. Latent class modeling was used to identify patterns of HF dyadic management.

RESULTS

The mean age of the 62 patients and their care partners was 59.7 ± 11.8 and 58.1 ± 11.9 years, respectively. A majority of patients (71.0%) had class III/IV HF, and a majority of the couples (95.2%) were married. Two distinct dyadic patterns were observed, 1 collaborative management type (n = 42, 67.7%) and 1 autonomous management type (n = 20, 32.3%). Dyads in the autonomous pattern were mostly female patients with male care partners; patients in this pattern also were more anxious and depressed, and reported worse relationship quality compared with collaborative dyads.

CONCLUSION

There is an engendered spectrum of collaboration in how HF patient-care partner dyads work together to manage HF that needs to be considered in clinical care and research.

Identifying unique profiles of perceived dyspnea burden in heart failure

BACKGROUND

Dyspnea is a common symptom of heart failure (HF) but dyspnea burden is highly variable.

OBJECTIVES

Identify distinct profiles of dyspnea burden and identify predictors of dyspnea symptom profile.

METHODS

A secondary analysis of data from five studies completed at Oregon Health and Science University was conducted. The Heart Failure Somatic Perception Scale was used to measure dyspnea burden. Latent class mixture modeling identified distinct profiles of dyspnea burden in a sample of HF patients (n = 449). Backwards stepwise multinomial logistic regression identified predictors of latent profile membership.

RESULTS

Four profiles of dyspnea burden were identified: no dyspnea/not bothered by dyspnea, mild dyspnea, moderate exertional dyspnea, and moderate exertional dyspnea with orthopnea and PND. Higher age was associated with greater likelihood of not being bothered by dyspnea than having moderate exertional dyspnea with orthopnea and PND. Higher NYHA class, anxiety, and depression were associated with greater likelihood of greater dyspnea burden.

CONCLUSIONS

Burden of dyspnea is highly variable among HF patients. Clinicians should account for the nuances of dyspnea and the activities that induce dyspnea when assessing HF patients.

Dyadic appraisals, dyadic coping, and mental health among couples coping with stroke: A longitudinal study protocol

AIM

The aim of this study is to describe a longitudinal research protocol for exploring the relationship of dyadic appraisal, dyadic coping (DC), and dyadic mental health among stroke survivors and their spouses and its action path.

BACKGROUND

Stroke can be considered as a dyad phenomenon which affects the mental health of both the survivors and their spouse caregivers. Studies based on dyadic theories are needed to examine the roles of dyadic appraisal and DC on the mental health of stroke dyads.

DESIGN

Longitudinal study.

METHODS

Stroke survivors and their spouse caregivers will be recruited from hospital, when the survivors are stable and about to discharge. Follow-up assessments will take place in 3, 6, 9, and 12 months after participants discharge. The structural equation modelling will be used for statistic analysing.

DISCUSSION

Our study seeks to expand the theory of Developmental-Contextual Model to examine the association among variables including dyadic appraisal, DC, and mental health for the couples coping with stroke.

Correlation between quality of life of cardiac patients and caregiver burden

Background

Caregivers experience high strain related to care giving. There is increasing interest in examining the caregiver burden of cardiac patients and studying the characteristics of caregivers.

Purpose

To explore the correlation between quality of life cardiac patients and caregiver’s burden.

Methods

A cross-sectional design using a convenience sample of caregivers and patients with cardiac conditions. Sociodemographic sheet, Dutch Objective Burden Inventory (DOBI), and Quality of Life (QLI-Cardiac 4). Linear regression was used to explore the predictors.

Results

200 caregivers and 200 patients with cardiac diseases completed the study. The overall mean scores of both DOBI and QLI-4 indicated moderate results 1.51(SD 0.4), 19.8 (SD 4.7) respectively. Predictors of caregiver burden were young, less educated caregivers and high QoL of cardiac patients.

Conclusion

Caregivers should receive more support and training from healthcare providers to develop their coping and resilience skills in a way that decreases their care burden and improves their quality of care and self-confidence.

Heart Failure Care Dyadic Typology: Initial Conceptualization, Advances in Thinking, and Future Directions of a Clinically Relevant Classification System

BACKGROUND

Heart failure (HF) dyadic self-care science is advancing rapidly, as evidenced by recent theoretical work, literature reviews, and multiple empiric studies. Typologies, once considered archaic, are now viewed as person-oriented classification systems that allow a whole-system view of information patterns. This whole-system view is particularly needed to understand complex tasks like dyadic HF self-care.

PURPOSE

The purpose of this article is to review the initial conceptualization of an HF care dyadic typology and the present advances in our thinking and suggest future directions for this clinically relevant classification system.

CONCLUSIONS

Development and testing of the typology across 5 studies resulted in a well-characterized, pragmatic and parsimonious, person-oriented classification system for understanding how patients and informal caregivers conduct patients' HF self-care at home. The 4 types are characterized as 2 individually oriented types-type I, patient oriented; type II, caregiver oriented; and 2 relationally oriented types-type III, collaboratively oriented; and type IV, incongruently oriented. We have devised a single-item measure of typology group that can be assessed in the clinical setting. Once this information is ascertained, the clinician can personalize the plan of care to the realities of the dyad.

IMPLICATIONS

Dyads that disagree on who is responsible for self-care may forego or delay action, resulting in self-care failures with subsequent HF advancement, hospitalization, and mortality. As the HF dyadic self-care science has advanced, we have come to appreciate the complexity that arises when 2 individuals work together on 1 complex task-HF self-care.

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.

Understanding the family care dyad: A comparison of two multilevel models

Although there has been increasing attention on a dyadic perspective of illness, contemporary dyadic research methods are still rarely utilized in cardiovascular disease. The focus of this paper is to describe the advantages of two types of multilevel dyadic models (the matched pairs model and the lesser known incongruence model). Data exemplars in a sample of heart failure family dyads are used to illustrate the distinct advantages of these two related multilevel dyadic models with particular emphasis on alignment with research questions. The more commonly known matched pairs model examines separate outcomes for each member of the dyad, controlling for the interdependent nature of the data. By re-parameterizing this model into a univariate dyadic outcomes model, researchers can address distinct, and sometimes more appropriate, research questions (e.g. incongruent appraisals of the illness experience). This paper promotes greater application of these methods in cardiovascular research to further understanding of the dyadic experience and more appropriately target interventions.

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.

Care Values in Dementia: Patterns of Perception and Incongruence Among Family Care Dyads

BACKGROUND AND OBJECTIVES

Persons with dementia (PWDs) often place greater importance on their care values (i.e., maintaining autonomy and social relations, choosing caregivers, avoiding being a burden) than family caregivers (CGs) perceive, which can detract from dementia care planning (e.g., care arrangements or surrogate decisions). Notable variability has been found across family care dyads (PWD and CG) in their perceptions of care values, suggesting that there may be multiple patterns of perception. The purpose of this study was to characterize distinct patterns of perception of care values in family care dyads.

DESIGN AND METHODS

Using cross-sectional data from 228 community-dwelling family care dyads, we quantified dyads' average perceptions and incongruence in perceptions of the importance of everyday care values using multilevel modeling. These scores were then used in a latent class analysis to identify distinct patterns of perception, with the dyad as the unit of analysis.

RESULTS

Two distinct patterns of care value perception were identified. 25% of dyads were labeled as "CG underestimating" due to lower average estimations of the importance of PWDs' care values, and a significant amount of dyadic incongruence. Underestimating dyads were characterized by a confirmed diagnosis of dementia, lower cognitive function, and younger age in PWDs, and higher relationship strain in the dyad.

IMPLICATIONS

Care dyads that fall into an underestimating pattern may be at greater risk for inadequate dementia care planning. Interventions to improve care planning in this higher-risk group may include care values identification with the PWD, strategies for alleviating relationship strain, early-stage planning, and disease education.

Heart Failure Self-care Within the Context of Patient and Informal Caregiver Dyadic Engagement: A Mixed Methods Study

BACKGROUND

Recent heart failure (HF) patient and informal caregiver (eg, dyadic) studies have either examined self-care from a qualitative or quantitative perspective. To date, the 2 types of data have not been integrated.

OBJECTIVE

The aim of this study was to understand HF self-care within the context of dyadic engagement.

METHODS

This was a cross-sectional, mixed methods (quantitative/qualitative) study. Heart failure self-care was measured with the Self-care of Heart Failure Index (v.6) dichotomized to adequate (≥70) or inadequate (<69). Dyadic symptom management type was assessed with the Dyadic Symptom Management Type scale. Interviews regarding self-care were conducted with both dyad members present. Content analytic techniques were used. Data were integrated using an information matrix and triangulated using Creswell and Plano Clark's methods.

RESULTS

Of the 27 dyads, HF participants were 56% men, with a mean age of 77 years. Caregivers were 74% women, with a mean age of 66 years, representing spouses (n = 14) and adult children (n = 7). Quantitatively, few dyads scored as adequate (≥70) in self-care; the qualitative data described the impact of adequacy on the dyads' behavior. Dyads who scored higher, individually or both, on self-care self-efficacy and self-care management were less likely to change from their life course pattern. Either the patient or dyad continued to handle all self-care as they always had, rather than trying new strategies or reaching out for help as the patient's condition deteriorated.

CONCLUSIONS

Our data suggest links that should be explored between dyadic adequacy and response to patients' symptoms. Future studies should assess dyadic adequacy longitudinally and examine its relationship to event-free survival and health services cost.

Patterns, relevance, and predictors of dyadic mental health over time in lung cancer

OBJECTIVE

To identify distinct patterns of dyadic mental health in a sample of lung cancer dyads over 12 months and associations with other health characteristics and individual, dyadic, and familial predictors.

METHODS

A sample of 113 patient-care partner dyads living with nonsmall cell lung cancer were examined five times over 12 months. An integrative multilevel and mixture modeling approach was used to generate dyadic mental health summaries and identify common dyadic patterns of mental health over time, respectively.

RESULTS

Three distinct patterns of dyadic mental health were observed: a congruent pattern (32.7%) characterized by almost identical mental health between members of the dyad, a disparate pattern (29.2%) characterized by better mental health of the patient compared with the care partner, and a parallel pattern (38.1%) characterized by care partner patterns of improvement and greater similarity in mental health over time. Membership of patterns was associated with physical health characteristics of both patient and care partner, levels of patient concealment regarding worries and concerns, and relationship quality reported by the care partner. Patterns did not differ by patient gender, care partner strain, or levels of social support.

CONCLUSIONS

Findings emphasize the importance of examining patterns of dyadic mental health to identify dyads most at risk so we may optimize the health of the dyad in tailored ways.

Patient and Caregiver Determinants of Patient Quality of Life and Caregiver Strain in Left Ventricular Assist Device Therapy

BACKGROUND

Although current guidelines emphasize the importance of social support to the success of left ventricular assist device (LVAD) therapy, few studies examine the influence of the caregiver on patient outcomes or quantify the impact of LVAD caregiving on caregiver outcomes. The purpose of this analysis was to identify patient and caregiver determinants of patient quality of life (QOL) and caregiver strain in response to LVAD therapy.

METHODS AND RESULTS

Data on patients receiving LVAD therapy and their caregivers (n=50 dyads) were prospectively collected pre-implantation and 1, 3, and 6 months post-implantation. Growth curve modeling was used to describe change in patient QOL (Kansas City Cardiomyopathy Questionnaire) and caregiver strain (Multidimensional Caregiver Strain Index). Patient QOL improved most in the first month (β=23.22±3.76, P<0.001), followed by gradual gains over 6 months (β=1.90±0.64, P<0.01). Caregivers experienced worsening of strain in the first month (β=4.30±1.42, P<0.01), followed by gradual resolution to pre-implantation levels by 6 months (β=-0.71±0.23, P<0.01). Worse pre-implantation patient symptoms were associated with greater improvement in patient QOL (β=0.53±0.19, P<0.01) but worsening caregiver strain (β=0.15±0.07, P=0.04). Better relationship quality was associated with greater improvement in patient QOL (β=14.39±5.85, P=0.01) and less pre-implantation caregiver strain (β=-9.31±2.28, P<0.001). Nonspousal caregivers experienced less pre-implantation strain (β=-8.60±3.10, P=0.01), and patients with nonspousal caregivers had less improvement in QOL (β=-3.70±1.62, P=0.02).

CONCLUSIONS

A combination of patient and caregiver characteristics predicts patient and caregiver response to LVAD therapy. Including caregiver factors in future studies may be helpful in developing interventions that improve patient and caregiver outcomes, together.

The Theory of Dyadic Illness Management

Despite the importance of both members of the adult patient-care partner dyad, a majority of research on illness management is focused on the patient or the care partner. The basic principle of the Theory of Dyadic Illness Management is that illness management is a dyadic phenomenon; the theory focuses extensively on the dyad as an interdependent team. The way dyads appraise illness as a unit influences the ways in which they engage in behaviors to manage illness together in a recursive fashion that influences dyadic health. Optimizing the health of both members of the dyad is a goal of the theory. In turn, the health of the dyad can feedback to influence how they appraise and manage illness together. Finally, dyadic illness management is an inherently variable process that is influenced by several contextual factors. Supportive evidence and implications for practice and future research are presented.

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

BACKGROUND

Patient's knowledge about heart failure (HF) contributes to successful HF self-care, but less is known about shared patient-caregiver knowledge.

OBJECTIVES

The purpose of this analysis was to: 1) identify configurations of shared HF knowledge in patient-caregiver dyads; 2) characterize dyads within each configuration by comparing sociodemographic factors, HF characteristics, and psychosocial factors; and 3) quantify the relationship between configurations and patient self-care adherence to managing dietary sodium and HF medications.

METHODS

This was a secondary analysis of cross-sectional data (N = 114 dyads, 53% spousal). Patient and caregiver HF knowledge was measured with the Atlanta Heart Failure Knowledge Test. Patient dietary sodium intake was measured by 3-day food record and 24 h urine sodium. Medication adherence was measured by Medication Events Monitoring System caps. Patient HF-related quality of life was measured by the Minnesota Heart Failure Questionnaire; caregiver health-related quality of life was measured by the Short Form-12 Physical Component Summary. Patient and caregiver depression were measured with the Beck Depression Inventory-II. Patient and caregiver perceptions of caregiver-provided autonomy support to succeed in heart failure self-care were measured by the Family Care Climate Questionnaire. Multilevel and latent class modeling were used to identify dyadic knowledge configurations. T-tests and chi-square tests were used to characterize differences in sociodemographic, clinical, and psychosocial characteristics by configuration. Logistic/linear regression were used to quantify relationships between configurations and patient dietary sodium and medication adherence.

RESULTS

Two dyadic knowledge configurations were identified: "Knowledgeable Together" (higher dyad knowledge, less incongruence; N = 85, 75%) and "Knowledge Gap" (lower dyad knowledge, greater incongruence; N = 29, 25%). Dyads were more likely to be in the "Knowledgeable Together" group if they were White and more highly educated, if the patient had a higher ejection fraction, fewer depressive symptoms, and better autonomy support, and if the caregiver had better quality of life. In unadjusted comparisons, patients in the "Knowledge Gap" group were less likely to adhere to HF medication and diet. In adjusted models, significance was retained for dietary sodium only.

CONCLUSIONS

Dyads with higher shared HF knowledge are likely more successful with select self-care adherence behaviors.
