Examining the Relationship Between Patient Fatigue-Related Symptom Clusters and Carer Depressive Symptoms in Advanced Cancer Dyads: A Secondary Analysis of a Large Hospice Data Set

Understanding and addressing factors affecting carers' mental health during end-of-life caregiving: synopsis of meta synthesis of literature and stakeholder collaboration

Background

Family carers provide crucial support to patients nearing end of life. This can affect carers' own mental health negatively. It is important to understand what factors may affect carers' mental health and convey this information to stakeholders who can effect change. We conducted reviews of the qualitative, observational and intervention carer literature and worked with carer advisors and other stakeholders to make findings useful and accessible.

Aim of the synopsis

To provide a synopsis of (1) project methods, (2) findings and implications from the evidence syntheses, (3) outcomes of our carer Review Advisory Panel collaboration and (4) feedback from wider stakeholder consultation.

Method

Searches of MEDLINE, Cumulative Index to Nursing and Allied Health Literature, PsycInfo, Social Sciences Citation Index, EMBASE, Cochrane Central Register of Controlled Trials and Database of Abstracts of Reviews of Effects 1 January 2009-24 November 2019. Studies included adult family carers for adult patients at the end of life cared for at home, considering any factor related to carer mental health. Collaboration with the Review Advisory Panel over nine meetings helped map review findings into a framework, shape their presentation and create Review Advisory Panel recommendations. Four workshops, two discussion groups and a survey with stakeholders (carers/patients, practitioners and policy-makers/commissioners) informed output formats and suggested actions.

Results

Thirty-one qualitative, 60 observational, 12 intervention and 3 mixed-methods studies were identified. Factors associated with carer mental health were: (1) patient condition, mainly psychological symptoms and quality of life; (2) impact of caring responsibilities, mainly life changes, workload and carer burden; (3) relationships, particularly carer-patient; (4) finances, whether sufficient; (5) internal processes, particularly self-efficacy; (6) support, particularly adequacy and quality; and (7) contextual factors, mainly age and gender. The Review Advisory Panel comprised five carers and a carer chair. They created recommendations for supporting carers based on syntheses findings, including: awareness raising for carers and practitioners; a road map to help carers navigate caregiving; bespoke carer support through carer assessment; assessment of patient's actual rather than 'managed' needs; co-ordinated care through a single contact point; addressing basic practical needs. Other key recommendations included holistic, co-ordinated patient care and cover of basic carer financial needs. Thirty-six stakeholders participated in workshops and discussion groups and 43 in the survey, to review synthesis findings and Review Advisory Panel recommendations. Stakeholders generally valued the qualitative evidence and recommendations over the quantitative evidence, although all outputs resonated with them. There was little consensus regarding where responsibility for carers may lie, pointing to a need for bespoke carer support roles. Some issues may require systemic-level changes.

Limitations

Findings are from Organisation for Economic Co-operation and Development country English-language publications on adult carers and patients within home care, and carer advisors and stakeholders were based in the United Kingdom, which may limit the transferability of findings.

Conclusions

Findings provide some clear indicators of factors affecting carer mental health and recommendations. Improvements may require investment in bespoke carer support roles (e.g. carer support nurses) and systemic change (e.g. improving carer identification and assessment, and financial security). Given the enormous contribution carers make to health and social care, they deserve such investment to support them in their work.

Lessons Learned Establishing the Palliative Care Research Cooperative's Qualitative Data Repository

Data sharing is increasingly an expectation in health research as part of a general move toward more open sciences. In the United States, in particular, the implementation of the 2023 National Institutes of Health Data Management and Sharing Policy has made it clear that qualitative studies are not exempt from this data sharing requirement. Recognizing this trend, the Palliative Care Research Cooperative Group (PCRC) realized the value of creating a de-identified qualitative data repository to complement its existing de-identified quantitative data repository. The PCRC Data Informatics and Statistics Core leadership partnered with the Qualitative Data Repository (QDR) to establish the first serious illness and palliative care qualitative data repository in the U.S. We describe the processes used to develop this repository, called the PCRC-QDR, as well as our outreach and education among the palliative care researcher community, which led to the first ten projects to share the data in the new repository. Specifically, we discuss how we co-designed the PCRC-QDR and created tailored guidelines for depositing and sharing qualitative data depending on the original research context, establishing uniform expectations for key components of relevant documentation, and the use of suitable access controls for sensitive data. We also describe how PCRC was able to leverage its existing community to recruit and guide early depositors and outline lessons learned in evaluating the experience. This work advances the establishment of best practices in qualitative data sharing.

Self-report of symptom cluster experiences in cancer patient-caregiver dyads

PURPOSE

Symptom clusters have important health implications in the context of cancer, but the symptom cluster experiences of cancer caregivers and patient-caregiver dyads are not well studied. To date, most studies report statistically derived symptom clusters among patients and fail to consider the caregivers' experience. This study aimed to assess and characterize self-reported symptom cluster experiences in cancer patient-caregiver dyads.

METHODS

We recruited 30 patient-caregiver dyads from the outpatient oncology clinics at a Comprehensive Cancer Center in the Midwestern U.S. Participants completed web-based surveys reporting their symptom clusters at weekly intervals over 8 weeks of cancer treatment.

RESULTS

Among 48 eligible dyads, 30 (63%) agreed to participate, 29 provided data, and ≥ 80% (24 patients, 26 caregivers) completed the study. Twenty-eight patients (97%) and twenty-two caregivers (76%) reported experiencing symptoms in clusters. There was substantial variability in the symptoms reported, perceived causality, and directional relationships among symptoms, however both patients' and caregivers' frequently described symptom clusters with psychoneurologic components (co-occurring pain, fatigue, sleep disturbance, anxiety, depression, lack of appetite and/or cognitive disturbance). Symptom clusters were perceived to have a moderate impact on patients' daily lives and a mild-to-moderate impact on caregivers' daily lives.

CONCLUSION

Dyad members experienced and successfully self-reported symptom clusters, with psychoneurologic symptom clusters prevalent among both patients and their caregivers. Self-report of symptom cluster experiences provides unique insight relevant to clinical management. Findings provide foundational support for development and testing of dyad-based interventions to mitigate symptom clusters and their negative impact on daily life among cancer-patient caregiver dyads.

Xerostomia in patients with advanced cancer: a scoping review of clinical features and complications

BACKGROUND

The aim of this project was to review the literature on dry mouth / xerostomia in patients with advanced cancer, with the objectives being to determine its prevalence, clinical features, and complications.

METHODS

Standard methodology was used to conduct this scoping review. Detailed searches of the Medline, Embase, CINAHL, and PsycInfo databases were conducted to identify relevant studies: eligible studies had to include patients with advanced cancer, and to contain details of clinical features and/or complications of xerostomia. Commercial bibliographic / systematic review software was used to support the process.

RESULTS

Forty-three studies were discovered from the database and hand searches. The studies included 23 generic symptom studies, eight "symptom cluster" studies, nine oral symptom / problem studies, and three xerostomia-specific studies. In depth data is described on the clinical features and complications of xerostomia, and on the "symptom clusters" including xerostomia, in this cohort of patients.

CONCLUSION

This review discovered a relatively small number of focused studies (involving a similarly small number of patients). Nonetheless, it demonstrates that xerostomia is a very common problem in patients with advanced cancer and is often associated with significant morbidity (and impairment of quality of life).

Symptom clusters among breast cancer patients in relation to chemotherapy cycles: a longitudinal study

PURPOSE

The aim of this study was to identify symptom clusters in breast cancer patients undergoing adjuvant chemotherapy.

METHODS

A prospective longitudinal study was conducted. And a sample of 620 breast cancer patients receiving adjuvant chemotherapy was recruited using convenience sampling from May 20, 2020, to March 31, 2021. Data were collected eight times: the first chemotherapy cycle (T1) to the eighth cycle of chemotherapy (T8). Exploratory factor analysis was used to explore the composition of symptom clusters.

RESULTS

Symptoms with an incidence of less than 20% were deleted and the remaining symptoms were included in the factor analysis. Three common factors were extracted in T1, including gastrointestinal symptom cluster, emotional and psychological symptom cluster, and menopausal symptom cluster. Five common factors were extracted from T2 to T7, including gastrointestinal symptom cluster, emotional and psychological symptom cluster, neurological symptom cluster, menopausal symptom cluster, and self-image disorder symptom cluster. Four common factors were extracted at T8, including gastrointestinal symptom cluster, emotional and psychological symptom cluster, neurological symptom cluster, and menopausal symptom cluster.

CONCLUSION

Breast cancer patients undergoing adjuvant chemotherapy experience multiple symptoms and different symptom clusters in different chemotherapy cycles. It is a benefit for health care providers to better understand and care for breast cancer patients. It will also help such women to manage concurrent symptoms ahead to promote their quality of life.

Family Caregiver Reports of Their Own and Patient Symptoms in Cancer Home Hospice Approaching End-of-Life

Context: Family caregivers assume the primary responsibility of assessing and managing hospice cancer patient symptoms while simultaneously managing their own wellbeing and symptoms. Objectives: Describe caregivers' assessment of hospice cancer patient and their own symptoms during the last 60 days of patient life, and assess the relationship between patient and caregiver symptoms over time. Methods: Caregiver symptom report of self and cancer home hospice patient symptom data were collected via telephone in the final 60 days of patient life. Descriptive data on symptom severity and prevalence were summarized. Exploratory Factor Analysis was used to group individual symptoms. Factors representing patient symptoms, caregiver symptoms, and caregiver outlook were analyzed using mixed-effects analysis to determine relationships between factors and change in relationship between factors over time. Results: Data from 61 patient-caregiver dyads are presented. At least 1 day of moderate-to-severe symptoms were reported in the majority of dyads. Significant auto-regressive associations were found, namely previous factor scores for an individual positively predicted the next factor scores for that individual. Previous caregiver report of patient symptoms was also positively associated with the next report of caregiver symptoms; previous caregiver report of their own symptoms were negatively associated with their next report of patient symptoms. Patient and caregiver symptoms and caregiver outlook worsened over time and the relationship between patient and caregiver symptoms strengthened closer to death. Conclusion: Our findings may guide hospice care team responses to caregiver and patient symptoms to promote individual level and unit level functioning.

Predictors of psychoneurological symptoms in cancer caregivers over time: Role of caregiving burden, stress, and patient symptoms

PURPOSE

In cancer patients, stress is associated with a psychoneurologic (PN) symptom cluster of depressed mood, anxiety, pain, fatigue, and sleep disturbance. The stress of caregiving may trigger similar symptoms among caregivers and warrants investigation. The purpose of this analysis was to characterize correlates of PN symptom burden in cancer caregivers.

METHODS

Cancer patient-caregiver dyads (n = 29) provided eight weekly symptom reports using a web-based survey. Primary and secondary stressors of caregiving were also assessed. Mixed models accounting for repeated measurement were used to assess the between- and within-dyad predictors of caregiver PN symptom burden. The interaction of patient PN symptom burden and stress was tested. Exploratory cross-lagged Actor-Partner Interdependence Models were used to assess the week-to-week interdependence between patient and caregiver symptoms.

RESULTS

Caregivers most frequently reported feeling anxious (44% on average across timepoints), sleep problems (31%), fatigue (25%), and depressed mood (24%). Mixed models indicated that within dyads, greater hours of care and more patient symptoms were associated with greater caregiver PN symptom burden. Greater baseline perceived stress was also associated with higher caregiver PN symptom burden and moderated the association between patient and caregiver PN symptom burden. Cross-lagged Actor-Partner Interdependence Models indicated longitudinal interdependence among survivor and caregiver symptom burden.

CONCLUSIONS

The findings provide preliminary evidence of the interrelationship of PN symptom burden in caregivers and patients and the potential for stress to amplify this interrelationship, with implications for symptom management and supportive care practice.

The efficacy of psychosocial interventions for cancer caregiver burden: A systematic review and meta-analysis of randomized controlled trials

Caregivers of adults with cancer often provide prolonged demanding assistance (e.g., physical, emotional) to their loved ones, resulting in caregiver burden. This meta-analytic review examined the efficacy of psychosocial interventions in reducing caregiver burden in caregivers of adults with cancer. Randomized controlled trials (RCTs) were identified from six electronic databases and clinical trial registries. Random-effects meta-analyses were conducted for subgroups of interventions and control conditions. Overall, 90 records describing 50 RCTs showed that psychosocial interventions reduced caregiver burden compared to passive controls (e.g. wait-list) at post-intervention (g = 0.26, 95%CI [0.12, 0.40]), but not at the first follow-up (g = 0.10, 95%CI [-0.05, 0.24]). Subgroup analyses showed that compared to passive controls, therapeutic counseling and skills training interventions significantly reduced caregiver burden at post-intervention, whereas psycho-education/support interventions did not significantly reduce burden. Very few RCTs examined intervention efficacy compared to active controls (e.g., psycho-education/support). The evidence grade ranged from very low to moderate due to inconsistency and imprecision of the results. Therapeutic counseling and skills training interventions appear efficacious in improving caregiver burden at post-intervention, although these improvements attenuate over time. Rigorous trials examining intervention effects on long-term outcomes are needed to better understand the effective mechanisms to sustain reduction in caregiver burden.

Psychometric Properties of the Spanish Version of the Fatigue Assessment Scale in Caregivers of Palliative Care Patients

Symptoms of fatigue and lack of energy are very common in caregivers of palliative care (PC) patients, traditionally associated with variables such as burden or depression. There are no Spanish-language instruments validated for assessing fatigue levels in this population. The Fatigue Assessment Scale (FAS) is a useful and simple instrument for assessing fatigue in this group. The aim of this study was to examine its psychometric properties (factor structure, reliability and validity) in a sample of caregivers of PC patients. Instrumental design for instrument validation was performed. One hundred and eight caregivers of PC patients participated and completed measures of fatigue, family functioning, life satisfaction, caregiver burden, anxiety, depression, resilience and quality of life. A confirmatory factor analysis was performed; non-linear reliability coefficient and Pearson correlations and t-tests were conducted to assess evidence of reliability and validity. The Spanish version of the FAS was found to have a one-dimensional structure. Reliability was 0.88. Validity evidence showed that FAS scores were positively associated with levels of burden, anxiety and depression. They were negatively associated with family functioning, life satisfaction, resilience and quality of life. The Spanish version of the FAS in caregivers of PC patients shows adequate psychometric properties.

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.

The pre-efficacy phase testing for PAfitME™-A behavioral physical activity intervention to manage moderate and severe symptoms among advanced stage cancer patients

Fatigue and pain are the most frequently reported symptoms among advanced-stage cancer patients. Although physical activity (PA) is known to improve the aforementioned symptoms, few patients demonstrate the physically active behavior that adheres to the clinical guidelines regarding PA. The current article presents an exemplar that used the National Institute of Health's Obesity-Related Behavioral Intervention Trial (ORBIT) model and developed a behavioral intervention known as the personalized Physical Activity intervention with fitness graded Motion Exergames (PAfitME™). There were two phases of testing in the ORBIT model presented in the current paper. In Phase I testing, a standardized exergame prescription was evaluated by an advisory board and a single-case study was used to evaluate the personalized exergame prescription with personalization of the fitness levels. In Phase IIa, a within-group pre- and posttest design was used to evaluate the personalized exergame prescriptions with personalization of the fitness levels, self-efficacy, and variation in fatigue/pain. Subsequently, a complete intervention package was developed in accordance with a logic model, driven from the result of the Phase IIa testing with clinically significant findings. Currently, PAfitME™ is under Phase IIb testing in a randomized clinical trial with a control group. PAfitME™ employs a personalized approach to initiate and promote physically active behavior, to facilitate the management of fatigue and pain in cancer patients. Positive results from an efficacy trial would support the use of PAfitME™ in the management of fatigue and pain in advanced-stage cancer patients.
