Clinicians for CARE: A Systematic Review and Meta-Analysis of Interventions to Support Caregivers of Patients With Heart Disease

Depression Onset After a Spouse's Cardiovascular Event

Importance

Although cardiovascular disease (CVD) is a known risk factor for depression, evidence is lacking regarding whether and to what extent a spouse's CVD is associated with the subsequent mental health of individuals.

Objective

To examine the association between CVD onset in spouses and subsequent depression.

Design, Setting, and Participants

This cohort study examined 277 142 matched married couples enrolled in the Japan Health Insurance Association health insurance program between April 2015 and March 2022, covering approximately 40% of the working-age population in Japan. Index individuals (primary insured) whose spouses (dependent) experienced incident CVD between April 2016 and March 2022 were 1:1 matched to controls whose spouses did not experience CVD. Matching was based on age, sex, income, or the onset date of the spouses' CVD. Data analysis was conducted from April 2016 to March 2022.

Exposure

Spousal onset of CVD between fiscal years 2016 and 2021. The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes were used to identify the composite CVD outcomes (stroke, heart failure, and myocardial infarction).

Main Outcomes and Measures

Multivariate Cox proportional hazards models were used to investigate the association between spouses' new-onset CVD and individuals' depression, adjusting for sociodemographic characteristics and comorbidities of index individuals (diabetes, hypertension, and CVD) and spouses (diabetes, hypertension, and depression). Subgroup analyses were conducted according to sex, age, income levels, and history of CVD.

Results

Among 277 142 matched pairs of married couples, 263 610 (95.1%) had a male index individual; the mean (SD) age of index individuals was 58.2 (10.2) years. A new onset of depression was observed in 4876 individuals (1.8%). In multivariable Cox models, there was an association between the spouse's CVD and the individuals' depression (hazard ratio, 1.13 [95% CI, 1.07-1.20]). The subgroup analysis found no evidence of heterogeneity in sex, age, income level, or CVD history. The results were consistent when additionally adjusted for health behaviors (smoking, alcohol consumption, physical activity, and use of antihypertensive drugs) and objectively measured physical health conditions (body mass index, blood pressure, cholesterol levels, glucose levels, and estimated glomerular filtration rate) (hazard ratio, 1.16 [95% CI, 1.06-1.28]).

Conclusions and Relevance

In this nationwide cohort study of matched couples, a spouse's onset of CVD was associated with an increased risk of an individual's depression. These findings highlight the importance of preventive care for mental health disorders in individuals whose spouses experience incident CVD.

Feasibility of a Multi-Component Strengths-Building Intervention for Caregivers of Persons With Heart Failure

Caregivers of persons with heart failure (HF) navigate complex care plans, yet support strategies often focus solely on meeting the needs of patients. We conducted a randomized waitlist control trial (N = 38) to test the feasibility and gauge initial effect size of the Caregiver Support intervention on quality of life, caregiver burden, and self-efficacy among HF caregivers. The intervention includes up to five remote, nurse-facilitated sessions. Components address: holistic caregiver assessment, life purpose, action planning, resources, and future planning. Caregivers were 93.3% female, 60% White, and 63.3% spouses. Average age was 59.4. Participants who completed the intervention reported high satisfaction and acceptability of activities. Between-group effect sizes at 16 and 32 weeks suggest improvement in quality of life (mental health) (.88; 1.08), caregiver burden (.31; .37), and self-efficacy (.63; .74). Caregivers found Caregiver Support acceptable and feasible. Findings contribute evidence that this intervention can enhance caregiver outcomes. Clinicaltrials.gov Identifier NCT04090749.

Preventing Heart Failure Readmission in Patients with Low Socioeconomic Position

PURPOSE OF REVIEW

This review aims to summarize the current burden of heart failure (HF) in the United States, specifically in patients with low socioeconomic position (SEP), and synthesize recommendations to prevent HF-related hospital readmissions in this vulnerable population.

RECENT FINDINGS

As treatments have improved, HF-related mortality has declined over time, resulting in more patients living with HF. This has led to an increase in hospitalizations, however, putting excess strain on our healthcare system. HF patients with low SEP are a particularly vulnerable group, as they experience higher rates of hospitalization and readmission compared to their high SEP counterparts. The Hospital Readmission Reduction Program (HRRP) was created to motivate interventions that reduce hospital readmissions across diseases, with HF being a primary target. Numerous readmission prevention efforts have been suggested to target the pre-hospitalization, hospitalization, and post-hospitalization phases, including addressing social determinants of health (SDoH), improving coordination of care, optimizing discharge plans, and improving adherence to follow-up care and medication regimens. Many of these proposed interventions show promise in reducing HF-related readmissions and issues surrounding adequate caregiver support may be particularly important to reduce readmissions among persons in low SEP. Reducing HF-related hospital readmissions is possible, even in vulnerable populations like those with low SEP, but this will require coordinated efforts across the healthcare system and throughout the life course of these patients. Caregiver support is a necessary part of optimized care for low SEP HF patients and future efforts should consider interventions that support these caregivers.

Caregiver Stress Is Improved and Sustained Following Transcatheter Aortic Valve Replacement

Background

Little is known about the impact of symptomatic aortic stenosis and subsequent transcatheter aortic valve replacement (TAVR) on stress and health for the caregiver. In this prospective cohort study, we measured caregiver stress before and after TAVR.

Methods

We interviewed 34 primary caregivers for patients undergoing outpatient TAVR at an academic institution. Caregiver stress was measured using the Kingston Caregiver Stress Scale (KCSS) and the Caregiver Self-Assessment Questionnaire (CSAQ) before TAVR and at one and six months after. Mean scores were compared pre- and post-TAVR using the Wilcoxon signed-rank test.

Results

There was significant improvement in KCSS caregiver stress at one month that was sustained at six months post-TAVR (mean change -1.91 ± 2.50 for six months, p-value 0.01). This was primarily driven by improvement in caregiving issues rather than family or financial issues. There was also significant improvement in CSAQ self-assessed health/illness at one and six months (mean change -2.78 ± 4.01 for six months, p-value 0.016).

Conclusions

Our findings support further investigation of caregiver outcomes in shared decision making before TAVR.

Caregiver Distress and Coronary Artery Disease: Prevalence, Risk, Outcomes, and Management

PURPOSE OF REVIEW

Caregivers of patients with coronary artery disease (CAD) are integral to the health care system and contribute substantially to patients' management. The purpose of this review is to provide a narrative synthesis of existing research on caregiving for patients who experienced an acute coronary syndrome (MI/unstable angina) and/or coronary revascularization (PCI/CABG).

RECENT FINDINGS

Thirty-one articles are included in this review. Overall, caregiver distress is low to moderate, ranging from 6 to 67% of caregivers, and seems to dissipate over time for most caregivers. Interventions have demonstrated success in reducing the distress of caregivers of patients with CAD. Due to the heterogeneity in study samples, measurements used, and timing of assessments and programming, these results are far from definitive. Although evidence is accumulating, further advancement in caregiving science and clinical care is required to adequately understand and respond to the needs of caregivers throughout the patient's illness trajectory.

What are the needs and experiences of caregivers of people with heart failure? A qualitative study

BACKGROUND

The global burden of heart failure is estimated to be around 64 million people, with many needing care and support for daily living activities. These needs are usually filled by close relatives, often a spouse, and therefore someone of a similar age to the person for whom they care.

OBJECTIVES

The aim of this study was to explore the needs and experiences of caregivers caring for a person with heart failure through a qualitative interview approach.

METHODS

A qualitative study was conducted in a large region in South England. 17 caregivers were interviewed using a semi-structured approach and the data analysed using thematic analysis.

RESULTS

Four themes were identified from the data: a) Taking on the role of caregiver with the sub-themes of: acceptance and life changes; b) Getting to grips with being a caregiver with sub-themes: carrying out the care and coping with the care; c) Impact on own health and wellbeing: sub-themes of physical health and mental and emotional health and finally: d) Need for information and Support with sub-themes: trying to get knowledge and making sense.

CONCLUSIONS

This study has shown that heart failure caregiving can have a negative impact on caregivers' own health and wellbeing and involves complex care delivery for which they receive little support. Caregivers of people with heart failure report having significant information needs in order to understand the reasons for the care they provide yet feel marginalised by health care professionals.

Strengths-building through life purpose, self-care goal setting and social support: Study protocol for Caregiver Support

Background

For caregivers of people with heart failure, addressing a range of care recipient needs at home can potentially be burdensome, but caregivers may also gain meaning from caregiving. The Caregiver Support Program, a multicomponent strengths-based intervention, is designed to improve outcomes of heart failure caregivers.

Objectives

1) Test the feasibility and gauge an initial effect size of the Caregiver Support Program to improve caregiver quality of life (primary outcome), and fatigue and burden (secondary outcomes) from baseline to 16 weeks, 2) test whether fatigue and caregiver burden are associated with objective measures of resilience (sweat inflammatory cytokines (Il-6 and IL-10) and self-reported resilience, 3) evaluate changes in heart rate variability, IL-6 and IL-10, pre- and post-intervention.

Methods

This is a single-blind, two group, waitlist control trial. Eligible caregivers are 1) ≥ 18 years, 2) English speaking, 3) live with the person with heart failure or visit them at least 3 days per week to provide care, 4) provide support for at least 1 instrumental activity of daily living (IADL), 5) live within a 1 h driving radius of the Johns Hopkins Hospital, and 6) the care-recipient has been hospitalized within the last 6 months. Trial participants are randomized into the immediate intervention (n = 24) or waitlist control group (n = 24). Data collection is at baseline, 16 weeks, and 32 weeks.

Conclusion

The Caregiver Support program has the potential to increase quality of life and decrease fatigue and caregiver burden for caregivers of people with heart failure and multiple co-morbidities.
