Caregiver burden and health-related quality of life amongst caregivers of out-of-hospital cardiac arrest survivors

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.

Caregiver strain among relatives of out-of-hospital cardiac arrest survivors; the DANCAS relative survey

BACKGROUND

Knowledge about caregiver strain among relatives of out-of-hospital cardiac arrest (OHCA) survivors is limited. Thus, the objectives were to i) describe differences in self-reported mental well-being, mental health, and caregiver strain at different time points (1-5 years) post-OHCA and ii) investigate characteristics associated with caregiver strain.

METHODS

A national cross-sectional survey (DANCAS) from October 2020 to March 2021 with OHCA survivors and their closest relatives. The relative survey included the WHO-5 Well-being Index (WHO-5), the Hospital Anxiety and Depression Scale (HADS) and the Modified Caregiver Strain Index (M-CSI). Differences in scores between time groups were explored using descriptive statistics. Associations between characteristics and caregiver strain were investigated with multivariable logistic regression models, presented as odds ratios (OR) with 95% confidence intervals (CI), adjusted for gender, age, education status, relative affiliation, and time after OHCA.

RESULTS

Of 561 relatives, 24% (n = 137) experienced caregiver strain, with no significant differences in the relatives' mental well-being, mental health, or caregiver strain with time since OHCA. In the adjusted analyses, older age (OR 0.98 95% CI 0.96;0.99) and several self-reported outcomes, including reduced mental well-being (WHO-5 OR 7.27 95% CI 4.86;11.52), symptoms of anxiety (HADS-A OR 6.01 95% CI 3.89;9.29) and depression (HADS-D OR 15.03 95% CI 7.33;30.80) were significantly associated with worse caregiver strain.

CONCLUSION

Nearly one-quarter of relatives of OHCA survivors experience caregiver strain, with this proportion remaining unchanged with time. Several outcomes were associated with caregiver strain, emphasising the need to identify relatives at greater risk of burden following OHCA.

Caregiver burden and its predictors in adult epilepsy patients

OBJECTIVE

The aim of this study was to evaluate caregiver burden and factors associated with caregiver burden in caregivers of adults with epilepsy.

MATERIALS AND METHODS

This descriptive cross-sectional study was conducted with 107 patients with epilepsy and 107 their primary caregivers. Personal information form including sociodemographic data and Zarit Caregiver Burden Inventory (ZBI), were used for caregivers, and patient information form, Montreal Cognitive Assessment Scale (MoCA), Hospital Anxiety and Depression Scale (HADS), Epilepsy Quality of Life Scale (QoLIE-31) and Stigma Scale were used for patients.

RESULTS

Caregiver burden was found to be related to gender (p = 0.047), marital status (p = 0.008), income (p = 0.003), education level (p = 0.05) age at onset of epilepsy (p = 0.025) and type of therapy (p = 0.005). The scale scores for cognitive functions (p < 0.001), stigma (p < 0.001), anxiety (p = 0.001), depression (p = 0.005), and quality of life (p < 0.001) of the patient showed significant correlations with caregiver burden. In addition, caregiver burden was found to correlate with some caregiver characteristics such as caregivers' age (p = 0.041), gender (p < 0.001), education (p < 0.001), income (p = 0.001) and relationship with the patient (p = 0.016). Time spent on caregiving per day was also positively correlated with caregiving burden (p < 0.001). In regression analysis, the gender of the caregiver, the gender of the patient, the stigma level of patient, and the type of treatment were found to be predictors of care burden (p < 0.05, R2 = 0.61).

CONCLUSION

It was found that two-thirds of the families of patients with epilepsy experienced varying degrees of caregiver burden. In addition, it was determined that caregiver burden was associated with sociodemographic and numerous psychosocial factors of the patient as well as the caregiver. It is important that both the caregiver and the patient being cared for are closely evaluated in interventions to reduce the caregiver burden in patients with epilepsy.

Mediating effect of social support between caregiver burden and quality of life among family caregivers of cancer patients in palliative care units

PURPOSE

To identify factors influencing the quality of life of family caregivers with terminal cancer in Chinese palliative wards and to test whether social support mediates the relationship between caregiver burden and caregiver quality of life.

METHODS

A cross-sectional study design was used. Sociodemographic data were collected and the Quality of Life Scale, the Caregiver Burden Scale, and the Social Support Rating Scale were administered to Chinese family caregivers from December 2021 to December 2022. The factors influencing quality of life and caregiver burden were examined using the Mann‒Whitney U test and the Kruskal‒Wallis H test. The mediating role of social support was assessed using the bootstrap method.

RESULTS

Family caregivers' quality of life in Chinese terminal cancer palliative units was related to caregivers' daily care time, the caregiver-patient relationship, and patient age. Caregiver quality of life was negatively associated with caregiver burden and positively associated with social support. In addition, social support mediated the relationship between caregiver burden and caregiver quality of life.

CONCLUSION

Social support mediated the impact of caregiver burden on caregiver quality of life. Family, society, and palliative care institutions should be integrated to take actions to reduce family caregiver burden, increase social support, and transfer the positive aspects of specific cultural contexts to the culture of palliative care in general to collaboratively cope with various problems related to end-stage cancer.

Family experiences and health outcomes following a loved ones' hospital discharge or death after cardiac arrest: A scoping review

Aim

Synthesise the existing literature on experiences and health outcomes of family members of adult cardiac arrest patients either after hospital discharge or death and identify gaps and targets for future research.

Methods

Following recommended scoping review guidelines and reporting framework, we developed an a priori protocol and searched five large biomedical databases for all relevant studies published in peer-reviewed journals in the English language through 8/8/2022. Studies reporting either on the experiences or health outcomes of family members of adult cardiac arrest patients who survived to hospital discharge (i.e., co-survivors) or bereaved family members were included. Study characteristics were extracted and findings were reviewed for co-survivors and bereaved family members. We summarised practice recommendations and evidence gaps as reported by the studies.

Results

Of 44 articles representing 3,598 family members across 15 countries and 5 continents, 89% (n = 39) were observational. Co-survivors described caregiving challenges and difficulty transitioning to life at home after hospital discharge. Co-survivors as well as bereaved family members reported significant and persistent psychological burden. Enhanced communication, information on what to expect after hospital discharge or the death of their loved ones, and emotional support were among the top recommendations to improve family members' experiences and health outcomes.

Conclusion

Family members develop significant emotional burdens and physical symptoms as they deal with their loved ones' critical illnesses and uncertain, unpredictable recovery. Interventions designed to reduce family members' psychological distress and uncertainty prevalent throughout the illness trajectory of their loved ones admitted with cardiac arrest are needed.

Long-Term Outcomes after Non-Traumatic Out-of-Hospital Cardiac Arrest in Pediatric Patients: A Systematic Review

Long-term outcomes after non-traumatic pediatric out-of-hospital cardiac arrest (OHCA) are not well understood. This systematic review aimed to summarize long-term outcomes (1 year and beyond), including overall survival, survival with favorable neurological outcomes, and health-related quality of life (HRQoL) outcomes) amongst pediatric OHCA patients who survived to discharge. Embase, Medline, and The Cochrane Library were searched from inception to October 6, 2021. Studies were included if they reported outcomes at 1 year or beyond after pediatric OHCA. Data abstraction and quality assessment was conducted by three authors independently. Qualitative outcomes were reported systematically. Seven studies were included, and amongst patients that survived to hospital discharge or to 30 days, longer-term survival was at least 95% at 24 months of follow up. A highly variable proportion (range 10–71%) of patients had favorable neurological outcomes at 24 months of follow up. With regard to health-related quality of life outcomes, at a time point distal to 1 year, at least 60% of pediatric non-traumatic OHCA patients were reported to have good outcomes. Our study found that at least 95% of pediatric OHCA patients, who survived to discharge, survived to a time point distal to 1 year. There is a general paucity of data surrounding the pediatric OHCA population.

Long-term Outcomes of Post-Cardiac Arrest Patients with Severe Neurological and Functional Impairments at Hospital Discharge

BACKGROUND

Patients resuscitated from cardiac arrest who have severe neurological or functional disability at discharge require high-intensity long-term support. However, few data describe the long-term survival and health-care utilization for these patients.

METHODS

We identified a cohort of cardiac arrest survivors ≥ 18 years of age, treated at a single center in Western Pennsylvania from January 2010 to December 2019, with a modified Rankin scale (mRS) of 5 at hospital discharge. We recorded demographics, cardiac arrest characteristics, and neurological exam at hospital discharge. We characterized long term survival and mortality through December 31, 2020 through National Death Index query. We described survival time overall and in subgroups using Kaplan-Meier curves and compared using log-rank tests.We linked cases with administrative data to determine 30, 90 day, and one-year hospital readmission rate. For subjects unable to follow commands at discharge, we reviewed records from index hospitalization to the present to describe improvement in neurological status and return home.

RESULTS

We screened 2,687 patients of which 975 survived to discharge. We identified 190 subjects with mRS of 5 at hospital discharge who were sent to non-hospice settings. Of these, 43 (23%) did not follow commands at discharge. One-year mortality was 38% (n = 71) with a median survival time of 4.2 years (IQR 0.3-10.9). Duration of survival was shorter in older subjects but did not differ based on, sex, or ability to follow commands at hospital discharge. Within the first year of discharge, 58% (n = 111) of subjects had at least one hospitalization with a median length of stay of 8 days [IQR 3-19]. Of subjects who did not follow commands at hospital discharge, 5/43 (11%) followed commands and 9 (21%) were reportedly living at home on subsequent encounters.

CONCLUSIONS

Of survivors treated over a decade at our institution, 20% (n = 190) were discharged from the hospital with severe functional disability. One-year mortality was 38%, and hospital readmissions were frequent. Few patients discharged unable to follow commands regained the ability over the period of observation, but many did return to living at home. These data can help inform decision maker expectations for patient trajectory and life expectancy.
