Validation of two short versions of the Zarit Burden Interview in the palliative care setting: a questionnaire to assess the burden of informal caregivers

Understanding and alleviating informal caregiver burden through the development and validation of a caregiver strain index-based model in Taiwan

BACKGROUND

Quantifying the informal caregiver burden is important for understanding the risk factors associated with caregiver overload and for evaluating the effectiveness of services provided in Long-term Care (LTC).

OBJECTIVE

This study aimed to develop and validate a Caregiver Strain Index (CSI)-based score for quantifying the informal caregiver burden, while the original dataset did not fully cover evaluation items commonly included in international assessments. Subsequently, we utilized the CSI-based score to pinpoint key caregiver burden risk factors, examine the initial timing of LTC services adoption, and assess the impact of LTC services on reducing caregiver burden.

METHODS

The study analyzed over 28,000 LTC cases in Southern Taiwan from August 2019 to December 2022. Through multiple regression analysis, we identified significant risk factors associated with caregiver burden and examined changes in this burden after utilizing various services. Survival analysis was employed to explore the relationship between adopting the first LTC services and varying levels of caregiver burden.

RESULTS

We identified 126 significant risk factors for caregiver burden. The most critical factors included caregiving for other disabled family members or children under the age of three (β = 0.74, p < 0.001), the employment status of the caregiver (β = 0.30-0.53, p < 0.001), the frailty of the care recipient (β = 0.28-0.31, p < 0.001), and the behavioral symptoms of dementia in care recipients (β = 0.28-2.60, p < 0.05). Generally, caregivers facing higher burdens sought LTC services earlier, and providing home care services alleviated the caregiver's burden.

CONCLUSION

This comprehensive study suggests policy refinements to recognize high-risk caregivers better early and provide timely support to improve the overall well-being of both informal caregivers and care recipients.

Implementing Dementia Care Management into routine care: protocol for a cohort study in Siegen-Wittgenstein, Germany (RoutineDeCM)

INTRODUCTION

Dementia Care Management is an evidence-based model of care. It has proven its efficacy and cost-effectiveness and has been applied to different settings and different target groups. However, it is not available in routine care in Germany. The scientific evidence has influenced the National Dementia Strategy, in which one measure is to examine the possibility and requirements to implement it into routine care. The aim of this study is to implement Dementia Care Management into routine care in a selected region in Germany and evaluate the effect on participants.

METHODS AND ANALYSIS

For the duration of 12 months, n=90 patients and their informal caregivers with cognitive impairment are recruited in different routine settings in primary care (general hospital, physicians' network, ambulatory nursing service, counselling service) by partners in primary care. They receive an adapted Dementia Care Management (DeCM) to the specific setting using participatory methods. DeCM is delivered by specifically qualified dementia care managers and consists of a comprehensive assessment of healthcare needs followed by algorithm-based and person-based support in healthcare planning, implementing and monitoring. The duration of the intervention is 6 months and data assessments are conducted prior to (baseline), at the end of (follow-up 1, FU1) and 6 months after the end of the intervention (follow-up 2, FU2). Primary outcomes are unmet needs at FU1 and FU2. Secondary outcomes are antidementia drug treatment, neuropsychiatric symptoms and caregiver burden at FU1 and FU2. Further outcomes are cognition, frailty and health-related quality of life. A separate process evaluation accompanies the implementation.

ETHICS AND DISSEMINATION

The Ethics Committee of University Medicine Greifswald, Germany, has reviewed and approved the study (registration number BB110/22). All participants provide written informed consent prior to participation. The results will be disseminated in regional workshops, press, online media and talks. They will be submitted to international peer-reviewed scientific journals for publication and presented at scientific meetings and conferences. Furthermore, results will be discussed with the funder and presented to the steering committee of the National Dementia Strategy.

Self-Assessment Instruments for Supporting Family Caregivers: An Integrative Review

Family caregivers take on a variety of tasks when caring for relatives in need of care. Depending on the situation and the intensity of care, they may experience multidimensional burdens, such as physical, psychological, social, or financial stress. The aim of the present study was to identify and appraise self-assessment instruments (SAIs) that capture the dimensions of family caregivers' burdens and that support family caregivers in easily identifying their caregiving role, activities, burden, and needs. We performed an integrative review with a broad-based strategy. A literature search was conducted on PubMed, Google Scholar, Google, and mobile app stores in March 2020. After screening the records based on the eligibility criteria, we appraised the tools we found for their usefulness for family care and nursing practice. From a total of 2654 hits, 45 suitable SAIs from 274 records were identified and analyzed in this way. Finally, nine SAIs were identified and analyzed in detail based on further criteria such as their psychometric properties, advantages, and disadvantages. They are presented in multi-page vignettes with additional information for healthcare professionals. These SAIs have proven useful in assessing the dimensions of caregiver burden and can be recommended for application in family care and nursing practice.

A Characterization of Central Auditory Processing in Parkinson's Disease

Background

Research indicates that people with Parkinson's disease (PwPs) may experience challenges in both peripheral and central auditory processing, although findings are inconsistent across studies. Due to the diversity of auditory measures used, there is a need for standardized, replicable hearing assessments to clarify which aspects of audition are impacted in PWPs and whether they are linked to motor and non-motor symptoms.

Objective

To characterize auditory processes and their possible alteration in PwPs. To address this, we collected a comprehensive set of standardized measures of audition using PART, a digital testing platform designed to facilitate replication. Additionally, we examined the relationship between auditory, cognitive, and clinical variables in PwPs.

Methods

We included 44 PwPs and 54 age and education matched healthy controls. Assessments included detection of diotic and dichotic frequency modulation, temporal gaps, spectro-temporal broad-band modulation, and speech-on-speech masking.

Results

We found no statistically significant differences in auditory processing measures between PwPs and the comparison group (ps > 0.07). In PwPs, an auditory processing composite score showed significant medium size correlations with cognitive measures (0.39 < r<0.41, ps < 0.02) and clinical variables of motor symptom severity, quality of life, depression, and caretaker burden (0.33 < r<0.52, ps < 0.03).

Conclusions

While larger datasets are needed to clarify whether PwPs experience more auditory difficulties than healthy controls, our results underscore the importance of considering auditory processing on the symptomatic spectrum of Parkinson's disease using standardized replicable methodologies.

Nursing Support for Caregiver Burden in Family Caregivers of Patients With Cancer: A Scoping Review

Purpose: To identify nursing support for caregiver burden in family caregivers of patients with cancer. Methods: This scoping review was guided by Arksey and O'Malley's six-stage scoping review framework. All available published articles from database inception to July 31, 2023 were systematically searched through PubMed, CINAHL, CENTRAL, and Ichushi-Web of the Japan Medical Abstract Society databases with additional relevant studies from the article list. Each key journal was manually searched. Results: Overall, 502 articles were screened, and 34 were finally included. The results of the qualitative thematic analysis were categorized into 7 components of nursing support: psychological and educational support, psychological and educational support using mainly non-face-to-face (Information and Communication Technology), psychological and educational support mainly using non-face-to-face (telephone) methods, mindfulness to support, support aimed at reducing caregiver stress, support for both patients and caregivers, and others. Of the 34 studies, 23 were randomized controlled trials (RCT), and the remaining 11 were non-RCTs. Conclusion: The results of the scoping review categorized nursing support for caregiver burden in the family caregivers of patients with cancer into 7 components. Future research should examine the feasibility of implementing these components.

Developing a supportive and palliative care intervention for patients with allogeneic stem cell transplantation: protocol of a multicentre mixed-methods study (allo-PaS)

INTRODUCTION

Although allogeneic stem cell transplantation (allo-SCT) is a curative treatment for many haematological malignancies, it is often associated with a high morbidity and mortality. Yet, little is known about the needs for supportive and palliative care among allo-SCT recipients. Moreover, targeted interventions that reduce symptom burden and suffering are still lacking. The present study aims to inform a supportive-palliative care intervention for patients with allo-SCT and their informal carers by exploring their experience and assessing their needs, especially their existential concerns, regarding four research topics: symptom burden and quality of life; coexistence of a chance for cure and a relevant risk of dying; change in goals of care; dying phase.

METHODS AND ANALYSIS

This is a descriptive mixed-methods study in progress with a convergent parallel design. Data on the four research topics will be collected and analysed separately in three steps: (1) qualitative semi-structured interviews among 20 patients, 20 informal carers and 12 healthcare providers (HCPs) and focus groups among 12-24 HCPs; (2) a quantitative cross-sectional survey with validated questionnaires and self-developed questions among 100 patients, 100 informal carers and 50 HCPs; (3) a retrospective case analysis of all deceased patients who underwent an allo-SCT between 2010 and 2019, with collection of quantitative and qualitative data. The qualitative and quantitative data sets will be finally merged for comparison and interpretation. Results will serve to develop a supportive-palliative care intervention.

ETHICS AND DISSEMINATION

The Ethics Commission of the Faculty of Medicine of the University of Cologne approved this study (20-1370_2). The study results will be published in peer-review journals, be presented at congresses and will be translated into clinical practice through the development of the palliative-supportive care intervention.

Insomnia Symptoms Among Hospice Family Caregivers: Prevalence and Association with Caregiver Mental and Physical Health, Quality of Life, and Caregiver Burden

BACKGROUND

Poor sleep exacerbates mental health problems and reduces quality-of-life (QOL) but prevalence of insomnia symptoms among hospice family caregivers and associations of poor sleep with caregiver health and QOL outcomes are not known.

OBJECTIVE

To describe prevalence of insomnia symptoms among hospice family caregivers and compare anxiety, depression, self-rated health, QOL, and caregiver burden between hospice family caregivers with and without insomnia symptoms.

METHODS

Descriptive sub-study using data collected during baseline interviews of hospice family caregivers involved in a randomized clinical trial in Midwestern United States (xxxxxxxx). Caregivers were dichotomized based on Insomnia Severity Index (ISI) scores (8+ indicated insomnia symptoms).

RESULTS

Among 57 hospice family caregivers, the mean ISI score was 8.2; nearly half (49.1%) experienced insomnia symptoms. Compared to caregivers without insomnia symptoms, caregivers with insomnia symptoms reported 2.4 times greater mean anxiety scores (4.7 vs 11.4); 3.5 times greater mean depression scores (3.1 vs 10.7); 2.1 times greater caregiver burden scores (5.6 vs 11.8); and 1.3 times lower self-rated health (3.5 vs 2.8); 1.3 times lower total QOL scores (29.3 vs 22.6); including differences in emotional QOL (7.9 vs 2.2), social QOL (7.2 vs 3.0), and physical QOL (7.4 vs 5.3).

CONCLUSIONS

Hospice family caregivers experience high prevalence of insomnia symptoms; caregivers with insomnia symptoms report worse anxiety, depression, caregiver burden, QOL, self-rated health. Clinicians must screen hospice caregivers for poor sleep and mental health and offer supportive interventions that improve their sleep and health. Policy makers must expand hospice benefits to better support family caregivers.

Spirituality and Caregiver Burden of People with Intellectual Disabilities: an Empirical Study

In recent years, interest in topics related to disabilities has grown. However, little attention has been devoted to people who constantly care for family members with an intellectual disability (ID). Thus, this study evaluated the relationship between the caregiver burden of people with intellectual disabilities and spirituality. The applied method was quantitative, exploratory, descriptive, and cross-sectional. The instruments used to collect data were a sociodemographic questionnaire, including questions extracted from the WHOQOL-100 (spiritual domain), and the following scales: Centrality of Religiosity; Brief Spiritual Religious Coping; Religious and Spiritual Struggles; Zarit Burden Interview and Satisfaction with Life Scale. One hundred twenty-nine people participated in the study. The sample was categorized as “highly religious” (57.3%), and 61.24% had an overload classified between moderate (36.43%) and severe (24.81%). The use of positive spiritual/religious coping methods was considered medium (M  = 3.44), and religious and spiritual struggles were low (M  = 1.71). Results show that those who considered themselves “spiritual and religious” highly use positive spiritual religious coping and score light burden and more life satisfaction. Such results indicate the importance of being attentive to the role of this dimension when planning emotional, psychological, and existential/spiritual support assistance. Public policies should consider the spiritual and religious dimension of those exclusively caring for people with intellectual disabilities. Studies focusing on how spiritual care can be provided to this population should be intensified.

Zarit Caregiver Burden Interview: Psychometric Properties in Family Caregivers of People with Intellectual Disabilities

Caregivers of people with intellectual disabilities may feel overburdened in their work and experience negative psychological consequences. The purpose of this instrumental study was to determine the evidence of internal structure and reliability of the Zarit Caregiver Burden Interview scale. A total of 398 family caregivers, including women and men, participated (M = 47.33, SD = 10.44). The structure of the scale was evaluated by factor analysis and the McDonald Omega coefficient was used to estimate reliability. Sixteen models of the scale were tested, differing in number of items and factor structures. A model of 15 items and 4 dimensions (overload, competence, social relationship, and interpersonal relationship) obtained acceptable fit (χ² = 184.72; p < 0.001; CFI = 0.95; TLI = 0.94; RMSEA = 0.055; SRMR = 0.05) and reliability coefficients above 0.70 in their dimensions. It is concluded that the Zarit scale is valid and reliable for use in caregivers of people with intellectual disabilities.

Care partner support

Palliative care focuses on improving the quality of life of people living with serious illness and their family carers. However despite policy, clinical, and research evidence underpinning the importance of a family approach to care, as well as justification for early palliative care integration, systemic inadequacies have impeded the quality of family support. This chapter provides an overview of common concepts in caregiving, a framework through which carer well-being can be understood, and an overview of disease specific considerations for care partners. There are several main needs that are relevant to care partners across disease settings include (1) information and guidance to prepare them for the role; (2) how to alleviate discomfort for the person with illness; (3) enhancing skills for the physical tasks of the role; (4) strategies for managing the psychological, and financial implications of the care partner role; and (5) assistance in advance care planning and on preparing for the care recipient's death. Care partner coping is a result of complex interactions between stressors and mediators as they navigate chronic illness, but palliative providers with an understanding of these factors are well-positioned to address carer risk factors and provide appropriate support.

Integrating patient- and caregiver-reported outcome measures into the daily care routines of specialised outpatient palliative care: a qualitative study (ELSAH) on feasibility, acceptability and appropriateness

Background

The use of patient-reported outcome measures (PROM) and caregiver-reported outcome measures can raise the patient centeredness of treatment and improve the quality of palliative care. Nevertheless, the everyday implementation of self-report in patients and caregivers is complex, and should be adapted for use in specific settings. We aimed to implement a set of outcome measures that included patient and caregiver self- and proxy-reported outcome measures in specialised outpatient palliative care (SOPC). In this study, we explore how the Integrated Palliative Outcome Scale (IPOS), IPOS Views on Care (IPOS VoC) and the Short-form Zarit Caregiver Burden Interview (ZBI-7) can be feasibly, acceptably and appropriately implemented in the daily care routines of SOPC.

Methods

Five SOPC teams were trained, and used the outcome measures in daily practice. Team members were mainly nurses and physicians. To investigate their feedback, we used a multi-method qualitative design consisting of focus groups with SOPC-team members (n = 14), field notes of meetings and conversations with the SOPC teams. In an iterative process, we analysed the findings using qualitative content analysis and refined use of the outcome measures.

Results

We found that integrating patient and caregiver outcome measures into daily care routines in SOPC is feasible. To improve feasibility, acceptability and appropriateness, the resulting burden on patients and relatives should be kept to a minimum, the usefulness of the measures must be understood, they should be used considerately, and administration must be manageable. We removed ZBI-7 from the set of measures as a result of feedback on its content and wording.

Conclusions

SOPC-team members have reservations about the implementation of PROM in SOPC, but with appropriate adjustments, its application in daily care is feasible, accepted and perceived as appropriate. Previous to use, SOPC-team members should be trained in how to apply the measures, in the design of manageable processes that include integration into electronic documentation systems, and in ongoing evaluation and support. They should also be taught how useful the measures can be.

Anxiety, Depression, Quality of Life, Caregiver Burden, and Perceptions of Caregiver-Centered Communication among Black and White Hospice Family Caregivers

Background: Anxiety, depression, and reduced quality of life (QOL) are common problems for hospice family caregivers, but it is unknown if disparities in these experiences exist among Black and White caregivers. Objectives: To compare anxiety, depression, QOL, caregiver burden, and perceptions of caregiver-centered hospice team communication between Black and White hospice family caregivers. Design: Secondary analysis of baseline data from two randomized clinical trials. Setting/Subjects: Seven hundred twenty-two Black and White hospice family caregivers ages 18+ from Midwestern and Northeastern United States. Measurements: Measures included the Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire (PHQ-9), Caregiver Quality-of-Life Index-Revised (CQLI-R), Zarit Burden Interview (ZBI-7), and Caregiver-Centered Communication Questionnaire (CCCQ). Results: Black and White caregivers differed across demographic and socioeconomic variables. Nearly one-third of hospice family caregivers reported moderate-to-severe anxiety (32.1%) and moderate-to-severe depressive symptoms (32.0%). White caregivers reported lower QOL than Black caregivers (p = 0.04), specifically in emotional (p = 0.02) and social (p = 0.0005) domains. In multiple regression analyses controlling for caregiver and patient factors, we found no racial differences in depression, anxiety, QOL, caregiver burden, or perceptions of caregiver-centered hospice communication. Conclusions: Despite demographic and socioeconomic differences, Black and White hospice family caregivers experience similarly high levels of anxiety, depression, burden, and perceptions of hospice communication. Interventions to support hospice family caregivers across racial groups and research that identifies factors that mediate social determinants of health in this population are needed. The development and validation of culture-concordant mental health screening tools in racially diverse populations is recommended.

Understanding and Supporting Informal Cancer Caregivers

Informal caregivers invest a significant amount of time and effort to provide cancer patients with physical, psychological, information, and social support. These challenging tasks can harm their own health and well-being, while a series of social-ecological factors may also influence the outcomes of cancer caregiving. Several instruments have been developed to help clinicians and researchers understand the multi-dimensional needs and concerns of caregivers. A growing body of evidence indicates that supportive interventions including psychoeducation, skills training, and therapeutic counseling can help improve the burden, information needs, coping strategies, physical functioning, psychological well-being, and quality of life of caregivers. However, there is difficulty in translating research evidence into practice. For instance, some supportive interventions tested in clinical trial settings are regarded as inconsistent with the actual needs of caregivers. Other significant considerations are the lack of well-trained interdisciplinary teams for supportive care provision and insufficient funding. Future research should include indicators that can attract decision-makers and funders, such as improving the efficient utilization of health care services and satisfaction of caregivers. It is also important for researchers to work closely with key stakeholders, to facilitate evidence dissemination and implementation, to benefit caregivers and the patient.

Unsolved problems and unwanted decision-making in the last year of life: A qualitative analysis of comments from bereaved caregivers

OBJECTIVES

Patients in their last year of life, as well as their relatives, often feel that existent care structures of the healthcare system do not adequately address their individual needs and challenges. This study analyzes unmet needs in terms of unsolved problems and unwanted decision-making in the health and social care of patients in their last year of life from the perspective of bereaved caregivers.

METHODS

This qualitative study is based on free-text comments from informal caregivers of deceased patients collected as part of the Last-Year-of-Life-Study-Cologne (LYOL-C) using a postal survey. With qualitative content analysis, a category system with main and subcategories was developed in a multi-step process.

RESULTS

Free-text commentaries and demographic data were collected from 240 bereaved caregivers. Particularly outside of hospice and palliative care services, study participants addressed the following unsolved problems: poor communication with medical and nursing staff, insufficient professional support for informal caregivers, inadequate psycho-social support for patients, and poor management of pain and other symptoms. Respondents often stated that their relative had to be cared for and die outside their own home, which the relative did not want.

SIGNIFICANCE OF RESULTS

Our findings suggest the necessity for greater awareness of patients' and their relatives' needs in the last year of life. Addressing individual needs, integrating palliative and hospice care in acute hospitals and other healthcare structures, and identifying patients in their last year of life and their caregivers could help to achieve more targeted interventions and optimization of care.

Instruments to assess the burden of care for family caregivers of adult palliative care patients

BACKGROUND

A primary caregiver shares the illness experience of the patient and undertakes vital care work, alongside managing the patient's emotions, and is actively involved in care process without being paid. When faced with the palliative care patient's needs, caregivers are affected on multiple levels (physical, psychological and socio-economic), thereby experiencing a moderate or severe burden of care.

AIM

To identify assessment instruments for the burden of care for family caregivers that are suitable to be used in clinical practice.

METHOD

A narrative review was conducted using an electronic search in Pubmed, PsychINFO, CINAHL of articles published in English between 2009-2019, using the search terms: 'caregiver/family, caregiver/carer and burden and palliative care/hospice/end of life'. An assessment grid was developed to appraise the clinical use of identified instruments.

RESULTS

Of the 568 articles identified, 40 quantitative studies were selected using 31 instruments to measure the caregiver burden of cancer, noncancer and terminally ill patients. Most instruments 23 (74.11%) evaluate the psycho-emotional and, 22 (70.96%) the social domain, 12 instruments (38.7%) focused on the physical domain, three (9.67%) on the spiritual field and six instruments (19.35%) on economic aspects. For the multidimensional instruments, the assessment grid scored highest for the Burden Scale for Family Caregiver (BSFC).

CONCLUSION

The BSFC is the tool that seems to meet the most requirements, being potentially the most useful tool in clinical practice.

Evaluating the efficacy of an Advanced Care Planning Program for Health Decisions in patients with advanced heart failure: protocol for a Randomized Clinical Trial

Background

An Advanced Care Planning (ACP) program of health decisions is the result of a process of reflection and relationship-building between the patient, their relatives and health professionals. It is based on respect for patients’ autonomy, involving them in making decisions about their disease in a way that is shared between the medical team, the patient and their relatives. Up until now, the efficacy of an ACP has not been measured in the existing literature, and therefore it is unknown if these programs reach their goal. The main objective of our study is to evaluate the efficacy of an ACP program for decision-making in patients with advanced heart failure (HF) in comparison to usual follow up and care. This objective will be evaluated by the Patient Activation Measure test, which measures the participation and self-management of the patient in decision-making. Secondary objectives: to evaluate the effect of the program on quality of life, to know if the patients wishes expressed through the ACP program are fulfilled, to measure the impact of the program on patients’ caregivers, to determine the satisfaction of patients included in the program and to evaluate the effect on quality of death.

Methods

Randomized multicentre clinical trial at four hospitals in Madrid. Once they are included in the study, patients’ allocation to groups (control vs intervention) will be made by alternative sampling. ACP will be applied to the intervention group, whereas in the Control Group usual follow-up will be carried out in HF units. All patients will fulfil questionnaires and tests related to the objectives of the study again after a 12-month follow-up period in order to gauge the effect of ACP in patients with advanced HF.

Discussion

The characteristics of patients with advanced HF make them a model for designing ACP programs, given the high prevalence of this disease, the progressive increase in its incidence and it’s clinical characteristics. Until now, the efficacy of this type of program has not been measured, so this Clinical Trial can provide relevant data for future ACP projects.
