Sleep disturbances in caregivers of patients with advanced cancer: A systematic review

Protocol of Brief Behavioral Treatment for insomnia intervention for adult patients with cancer and their sleep-partner caregivers

Background

Sleep disturbance is common and problematic among both patients with cancer and their sleep-partner caregivers. Although one's sleep affects the partner's sleep, existing psychobehavioral interventions have targeted patients' and caregivers' sleep problems independently.

Methods

We adapt the Brief Behavioral Treatment for Insomnia (BBTI) for both adult patients and their sleep-partner caregivers in the context of cancer. This protocol is to test the feasibility and acceptability as well as to provide preliminary efficacy of the BBTI for Couples with Cancer (BBTI-CC) intervention, which is to reduce sleep disturbance and improving sleep quality of both adults with cancer and their sleep-partner caregivers. The intervention will be delivered weekly for 4 weeks. Questionnaire and daily sleep logs will be collected at baseline (T1) and one-week after conclusion of the intervention (T2). Satisfaction with the intervention will be assessed weekly for 4 weeks.

Results

We estimate 18 dyads will be enrolled (18 patients and 18 caregivers). We expect >75 % of eligible and screened dyads will enroll within the enrollment period, >80 % of enrolled dyads will complete the intervention, and >80 % of participants will report satisfaction across all acceptability measures. We also expect BBTI-CC will reveal a small-to-medium effect on sleep efficiency (primary outcome), overall sleep disturbance, subjective sleep quality, and insomnia severity (secondary outcomes).

Conclusions

Results will inform the feasibility and acceptability of conducting a dyadic sleep behavioral intervention, and provide preliminary efficacy data to guide further refinement of intervention content and procedure for adult patients with cancer and their sleep-partner caregivers.

Longitudinal Analysis of Cancer Family Caregiver Perception of Sleep Difficulty During Home Hospice

BackgroundSleep difficulty in caregivers is associated with poor physical and psychological outcomes. The purpose of this study was to describe family caregivers' perception of sleep difficulty through the hospice trajectory after a cancer diagnosis as predicted by age, sex, self-report of anxiety or depression, and cohabitation.MethodsWe conducted a secondary analysis of longitudinal data using multilevel modeling with nested model comparisons. Beginning with an unconditional growth model, predictors were added to nested models to test differential impact.ResultsCaregivers (n = 164) were predominately white (n = 160; 97%) and female (n = 113, 69%). We hypothesized that age, sex, history of anxiety or depression, and cohabitation would predict sleep difficulty. The cohabitation predictor model was a statistically significant model for caregiver perception of sleep difficulty that worsened throughout hospice caregiving (b = .184, χ 2 = 7.199, P = 0.027) but age, sex, and history of depression or anxiety did not improve model fit.ConclusionOur findings indicate that family caregivers who cohabitate exhibit increased perception of sleep difficulty over the course of hospice. Future studies and interventions for hospice family caregivers' sleep should consider cohabitation between the patient and the caregiver as a significant predictor of sleep difficulty to observe and potentially mediate the negative outcomes associated with caregiver sleep difficulty. Further, determining the underlying reasons for sleep difficulty in cohabitation (e.g., patient symptoms or treatments) should be explored.

Non-pharmacological interventions for sleep disturbance ("insomnia") in patients with advanced cancer: a scoping review

PURPOSE

Sleep disturbances are a common yet overlooked symptom in patients with advanced cancer. Pharmacological interventions have been widely used to manage sleep disturbances; however, concerns related to their adverse effects have resulted in a need for alternative interventions. The purpose of this scoping review is to appraise the published literature on the non-pharmacological management of sleep disturbances in patients with advanced cancer.

METHODS

This scoping review was completed using the recommended methodological framework. An extensive literature search was completed using five electronic databases (Medline, CINAHL, Embase, APA PsycINFO, CENTRAL) and the Cochrane library. There were no restrictions applied to the search in relation to the years published. Only studies published in the English language were included.

RESULTS

We identified 9 studies published between 2010 and 2023 which focused on non-pharmacological management of sleep disturbances in patients with advanced cancer. Specific interventions included cognitive behavioural therapy, mindfulness-based therapies, bright light therapy, sleep hygiene, and other non-standard interventions. Improvements in sleep disturbance were noted in all studies, but only some studies showed statistical significance.

CONCLUSION

This scoping review identified a relatively small number of relevant studies, involving a relatively small number of participants. Moreover, the studies involved very different interventions, with very different methodologies (including type/time of assessments). Thus, it is difficult to recommend any particular non-pharmacological intervention at this time. Nevertheless, non-pharmacological interventions undoubtedly have a role to play in the management of sleep disturbance in patients with advanced cancer.

The impact of unpaid caring on cognitive function: a rapid review

OBJECTIVES

Our review aimed to examine the role of unpaid care in influencing cognitive function independently or via risk factors for dementia.

METHOD

This rapid review, registered in PROSPERO and following PRISMA guidelines, searched EMBASE, MEDLINE, and APA PsycINFO databases for longitudinal studies comparing dementia, cognitive function and associated risk factors for dementia between carers and non-carers. Studies were assessed for quality. Data were synthesised narratively.

RESULTS

Five studies looked at cognitive function directly; others examined risk factors: depression, social isolation, physical activity, body-mass index, type 2 diabetes, high blood pressure, educational attainment, and alcohol consumption. Unpaid carers have increased risk of depression and social isolation, and younger carers have lower educational attainment. Studies evaluating the link between unpaid caring and cognitive decline suggest that caring at low and moderate intensities may act as a protective factor against cognitive decline, but not at higher intensities. Female gender and high-intensity caring significantly influence the strength of association between unpaid care and dementia risk factors.

CONCLUSION

The impact of unpaid caring on cognitive health is complex, influenced by factors like intensity of care and social and cultural context. Across all studies, high-intensity caring negatively impacts carers physical and mental health, which in turn affect their cognitive health.

An Integrative Review of the Support Needs of Informal Caregivers of Hematological Cancer Patients in the Period Immediately Following Discharge From Inpatient to Outpatient Care

BACKGROUND

Preparing informal caregivers for a patient's transition to outpatient care is an important component of safe, quality hematological cancer care. The development of many novel therapies and emerging treatments has created opportunities to address the needs of informal caregivers following the discharge of patients from inpatient settings.

OBJECTIVE

To review and synthesize the literature on the needs of informal caregivers of patients with a hematological malignancy postdischarge from inpatient care.

INTERVENTIONS/METHODS

Integrative review methodology was used to explore the body of evidence available. This included a quality appraisal of qualitative, quantitative, and mixed-methods research findings, subsequent data extraction, and inductive thematic synthesis.

RESULTS

One thousand eight articles were screened with 10 included in the review. Key insights into the needs of caregivers entering the outpatient setting were identified and grouped into key subheadings: Encountering complex emotions knowing what to know, little time for yourself, and collateral impact.

CONCLUSION

Findings convey the complex and multiple needs of informal caregivers of hematological cancer patients. With a growing population of people with hematological malignancies and innovations in outpatient cancer therapies, there is a pressing need to codesign interventions to support their caregivers.

IMPLICATIONS FOR PRACTICE

This review has identified a need for more robust research to coproduce interventions in collaboration with caregivers. In addition, interventions developed from further research should be tested in quality implementation science studies to determine their feasibility, sustainability, and impact on outcomes that matter to hematological cancer caregivers.

Examination of the relationship between the empathic tendencies and sleep quality of caregivers of cancer patients

PURPOSE

The present study aims to reveal the relationship between the empathic tendencies and sleep quality of caregivers of cancer patients.

MATERIAL AND METHOD

This cross-sectional study was conducted with caregivers of cancer patients registered in the oncology unit of a hospital between May and July 2024 (n = 346). The study data were collected using a sociodemographic information form, the Empathic Tendency Scale, and the Pittsburgh Sleep Quality Index. The data were analyzed using the Pearson correlation and hierarchical regression analyses as well as descriptive statistics.

FINDINGS

59.5% of the participants were female and 88.2% lived with patients. 62.7% of the cancer patients were male and 61.1% were partially dependent in daily life activities. The caregivers had a mean total score of 70.58 ± 16.85 on the Empathic Tendency Scale and a mean total score of 4.40 ± 3.94 on the Pittsburgh Sleep Quality Index. It was found that there was a negative, strong, and statistically significant relationship between the mean total scores on the Empathic Tendency Scale and the Pittsburgh Sleep Quality Index (r = - 0.924; p < 0.001). According to the hierarchical regression model, certain sociodemographic features of the caregivers explained the variance in empathic tendency (Adj. R2 = 0.607; p < 0.001), whereas when sleep quality components were added to the model, the variance in empathic tendency was explained (Adj. R2 = 0.896; p < 0.001).

CONCLUSION

The caregivers of cancer patients were found to have high empathic tendencies, which was associated with high sleep quality. Furthermore, low empathic tendencies among the caregivers were found to be primarily associated with increasing length of care and advancing patient age. The findings underscore the pivotal role that empathic approaches play in enhancing the quality of care, underscoring the necessity for augmented interventions that prioritize a compassionate approach, and the management of empathy in caregivers of cancer patients.

Symptom burden and quality of life among patient and family caregiver dyads in advanced cancer

PURPOSE

Symptom management among patients diagnosed with advanced cancer is a high priority in clinical care that often involves the support of a family caregiver. However, limited studies have examined parallel patient and caregiver symptom burden and associations with their own and each other's quality of life (QOL). This study seeks to identify patient and caregiver symptom clusters and investigate associations between identified clusters and demographic, clinical, and psychosocial factors (cognitive appraisals and QOL).

METHODS

This study was a secondary analysis of self-reported baseline survey data collected from a randomized clinical trial of 484 adult advanced cancer patients and their caregivers. Latent class analysis and factor analysis were used to identify symptom clusters. Bivariate statistics tested associations between symptom clusters and demographic, clinical, and psychosocial variables.

RESULTS

The most prevalent symptom for patients was energy loss/fatigue and for caregivers, mental distress. Low, moderate, and high symptom burden subgroups were identified at the patient, caregiver, and dyad level. Age, gender, race, income, chronic conditions, cancer type, and treatment type were associated with symptom burden subgroups. Higher symptom burden was associated with more negative appraisals of the cancer and caregiving experience, and poorer QOL (physical, social, emotional, functional, and overall QOL). Dyads whose caregivers had more chronic conditions were more likely to be in the high symptom burden subgroup.

CONCLUSION

Patient and caregiver symptom burden influence their own and each other's QOL. These findings reinforce the need to approach symptom management from a dyadic perspective.

Dyadic Investigation of Posttraumatic Stress Symptoms and Daily Sleep Health in Patients With Cancer and Their Caregivers

OBJECTIVE

Cancer can be a traumatic experience affecting multidimensional aspects of sleep among patients and caregivers. This study examined the differential associations of cancer-related posttraumatic stress symptoms (PTSS) with various sleep markers in this population.

METHODS

Patients newly diagnosed with colorectal cancer ( n = 138, mean age = 56.93 years, 31.88% female, 60.14% Hispanic, 6.53 months after diagnosis) and their sleep-partner caregivers ( n = 138, mean age = 55.32 years, 68.12% female, 57.97% Hispanic) completed questionnaires assessing the four PTSS clusters (intrusion, avoidance, alterations in arousal and reactivity, negative alterations in cognitions and mood). Participants also completed daily sleep diaries for 14 consecutive days, from which sleep onset latency (SOL), wake after sleep onset (WASO), and sleep duration were derived.

RESULTS

Actor-partner interdependence model revealed that caregivers' greater alterations in arousal and reactivity were associated with their own longer SOL ( b = 15.59, p < .001) and their patients' longer sleep duration ( b = 0.61, p = .014), whereas patients' arousal and reactivity were associated with their caregivers' shorter SOL ( b = -8.47, p = .050). Patients' and caregivers' greater negative alterations in cognitions and mood were associated with patients' longer SOL ( b = 9.15, p = .014) and shorter sleep duration ( b = -0.41, p = .050), respectively. Caregivers' greater intrusion was related to their own shorter SOL ( b = -10.14, p = .004).

CONCLUSIONS

The four PTSS clusters, particularly arousal and reactivity and negative cognitions and mood, have distinct associations with sleep markers individually and dyadically in patients and caregivers affected by cancer. Investigations of psychosocial and biobehavioral pathways underlying these relations are warranted. Tailored trauma treatments and sleep interventions may improve the well-being of this population.

Effects of heart rate variability biofeedback (HRVBFB) on sleep quality and depression among methamphetamine users

Methamphetamine is garnering concern due to its increasing use worldwide. Depression and sleep quality are major mental health issues in substance users. Heart rate variability biofeedback (HRVBFB) has shown promising results in terms of reducing depression and increasing sleep quality. The present study aimed to explore the effects of HRVBFB on these two issues in methamphetamine users. Sixty-one methamphetamine users were enrolled and allocated randomly into a treatment as usual (TAU) group and a HRVBFB plus TAU group. The levels of depressive symptoms and sleep quality were assessed at intake, end of the intervention, and end of follow-up. Compared with baseline, the levels of depressive symptoms and poor sleep quality were decreased at the end of the intervention and follow-up in the HRVBFB group. The HRVBFB group exhibited a greater decrease in depressive symptoms and a better improvement in sleep quality than the TAU group. The associations of HRV indices with levels of depressive symptoms and poor sleep quality were different in the two groups. Our results showed that HRVBFB is a promising intervention for reducing depressive symptoms and improving sleep quality in methamphetamine users. The benefits with respect to depressive symptoms and poor sleep quality can extend beyond the end of HRVBFB 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.

Insomnia Symptoms and Associated Factors in Caregivers of Adult Hospitalized Patients

Caregivers experience high levels of emotional stress and must cope with several clinical and hospital-related environmental factors that seriously impact their night’s rest. The purpose of this study was to establish the prevalence of insomnia symptoms in a sample of caregivers of adult hospitalized patients and to examine the relationships between insomnia symptoms and patient and caregiver-associated factors. A total of 152 caregivers were enrolled from the two main hospitals in Granada, Spain. Sociodemographic, economic, and care-related data were collected. Insomnia symptoms, burden, anxiety and depression, social support, and resilience were assessed. Information on patients’ hospital admission, dependence, and neuropsychiatric symptoms was also obtained. Most caregivers were middle-aged women caring for their spouses. Self-reported insomnia prevalence was set at 45.4%. Comparison analyses between caregivers suffering from insomnia symptoms and non-insomniacs showed significantly higher burden, anxiety and depression and patients’ neuropsychiatric symptoms (p < 0.05) and lower resilience and social support in the former (p < 0.01). A regression analysis showed that anxiety (ORa = 1.15; p < 0.05) and higher caregiver education level (ORa = 5.50; p < 0.05) were factors significantly associated with insomnia symptoms. Patients’ neuropsychiatric symptoms showed a trend toward statistical significance as well (ORa = 1.09; p = 0.06). There is an acute need to address, prevent and treat insomnia problems in caregivers.

Depression, anxiety, and sleep quality of caregivers of children with spinal muscular atrophy

BACKGROUND

The aim of this study was to evaluate the prevalence of anxiety, depression, sleep, and associated factors in caregivers of children with spinal muscular atrophy (SMA).

MATERIALS AND METHODS

Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory-State (STAI-S), the State-Trait Anxiety Inventory-Trait (STAI-T), and Pittsburgh Sleep Quality Index (PSQI) were used to assess the anxiety, depression, and sleep quality of the caregivers of children with SMA. Higher scores indicated worse outcome for all three questionnaires.

RESULTS

Fifty-six caregivers of children with SMA were included in the study. Median age of children was 6 (3.2-10) years and mean age of the caregivers was 37.0 ± 6.5 years. Median scores of the BDI, STAI-S, STAI-T, and PSQI were 12 (7.2-17), 35.5 (31-44), 40.5 (35-48), and 7.0 (5.0-10.0), respectively. There was a positive correlation between BDI and PSQI scores (p < 0.05). There was a negative correlation between the age of the caregivers and PSQI, BDI, STAI-T scores (p = 0.01, r = -0.341; p = 0.006, r = -0.364; p = 0.003, r = -0.395, respectively). There was a negative correlation between the age of the patients and the PSQI scores of the caregivers (p = 0.01, r = -0.33). There was a negative correlation between BDI scores and household income (p = 0.01, r = -0.34).

CONCLUSION

Caregivers of children with SMA had elevated depression and anxiety levels and they also had decreased sleep quality. Economic and social support resources are needed to help caregivers of those children.

Protocol of a dyadic sleep intervention for adult patients with cancer and their sleep-partner caregivers

Background

Sleep disturbance is common and problematic among both patients with cancer and their sleep partner caregivers. Although 70% of the general adult population sleep in the same bed with a significant other, as do adult cancer patients and their spousal/partner caregivers, and one's sleep affect the partner's sleep, existing psychobehavioral interventions have targeted patients' and caregivers' sleep problems independently.

Methods

We developed a new sleep intervention, My Sleep Our Sleep (MSOS), for both adult patients with cancer and their sleep-partner caregivers together. This protocol is to test the feasibility and acceptability as well as to provide preliminary efficacy of the MSOS intervention, which is a dyadic intervention designed to reduce sleep disturbance and improving sleep quality of both adult cancer patients and their sleep-partner caregivers (dyads). The intervention will be delivered weekly for 4 weeks. Questionnaire and daily sleep logs will be collected at baseline (T1) and one-week after conclusion of the intervention (T2). Satisfaction with the intervention will be assessed weekly for 4 weeks.

Results

We estimate 43 dyads be enrolled (43 patients and 43 sleep-partner caregivers). We expect >75% of eligible and screened dyads will enroll within the enrollment period, >80% of enrolled dyads will complete the intervention, and >80% of participants will report satisfaction across all acceptability measures. We also expect MSOS will reveal a small-to-medium effect on sleep efficiency (primary outcome), overall sleep disturbance, subjective sleep quality, and insomnia severity (secondary outcomes).

Conclusions

Results will inform the feasibility and acceptability of conducting a dyadic sleep intervention, and provide preliminary efficacy data to guide further refinement of the intervention content and procedure for adult patients with cancer and their sleep-partner caregivers.

Caregiving burdens of family members of patients living with hepatocellular carcinoma

BACKGROUND

Caregiving burden is common among family caregivers (FCs). In Taiwan, no reports have compared caregiving burden according to disease stage, or explored the comprehensive factors of caregiving burden in the FCs of patients with hepatocellular carcinoma (HCC).

AIM

The aim of the study was to investigate caregiving burden at different diagnosis stages and its potential predictors in the FCs of patients with hepatocellular carcinoma.

METHODS

This descriptive, cross-sectional study included 192 FCs. Caregiving burden was measured using the Caregiver Reaction Assessment tool. The predictive factors of caregiving burden in the FCs of patients with HCC were identified using a linear regression model.

RESULTS

The global caregiving burden had no significant differences between the four disease stages. The lack of family support and impact on schedule were significantly higher at the terminal stage than at the earlier stage. The risk factors of caregiving burden were high depression, high financial demand, heavy caregiving tasks, advanced age and frequent patient contact, which obtained a variance of 47.8% in the regression model.

CONCLUSION

Healthcare providers need to proactively identify and assess FCs with risk factors of caregiving burden and provide appropriate interventions specific to individual needs at different disease stages.

Impact of acceptance and commitment therapy on physical and psychological symptoms in advanced gastrointestinal cancer patients and caregivers: Secondary results of a pilot randomized trial

Patients with advanced gastrointestinal cancer often experience high symptom burden, which is associated with heightened distress in both patients and their family caregivers. Few interventions have been tested to jointly address patient and caregiver symptoms in advanced gastrointestinal cancer. In a randomized pilot trial, telephone-based, dyadic acceptance and commitment therapy (ACT) was found to be feasible in this population. The present secondary analyses examined the impact of this intervention on patient and caregiver physical and psychological symptoms. Patients and caregivers (N = 40 dyads) were recruited from clinics in Indianapolis, Indiana and randomized to either six weeks of telephone-based ACT or education/support, an attention control condition. Outcomes were assessed at baseline and at 2 weeks and 3 months post-intervention. Study group differences in outcomes were not statistically significant. However, when examining within-group change, only ACT patients experienced moderate reductions in pain severity and interference at 2 weeks post-intervention (effect size [ES]=-0.47; -0.51) as well as moderate reductions in depressive symptoms at 2 weeks (ES=-0.42) and 3 months (ES=-0.41) post-intervention. ACT caregivers experienced moderate reductions in sleep disturbance (ES=-0.56; -0.49) and cognitive concerns (ES=-0.61; -0.85) across follow-ups. Additionally, caregivers in both conditions experienced moderate reductions in fatigue (ES=-0.38 to -0.70) and anxiety (ES=-0.40 to -0.49) across follow-ups. Findings suggest that ACT may improve certain symptoms in dyads coping with advanced gastrointestinal cancer and warrant replication in a larger trial.

"It was terrible, I didn't sleep for two years": A mixed methods exploration of sleep and its effects among family caregivers of in-home hospice patients at end-of-life

BACKGROUND

Due to overnight caregiving demands; exacerbation of high rates of anxiety, depression, and distress; and inadequate support, millions of family caregivers of patients receiving in-home hospice are at risk of poor sleep and negative health effects.

AIM

To describe sleep experiences of family caregivers of in-home hospice patients and perceptions of these experiences on caregivers' wellbeing in the context of caregiver health and live-in status.

DESIGN

Developed using the Symptom Management Model, this mixed methods study featured a concurrent nested design prioritizing qualitative reflexive thematic analysis.

SETTING/PARTICIPANTS

About 47 family caregivers of in-home hospice patients from two randomized clinical trials (NCT03712410, NCT02929108) were interviewed (United States, 2021). Anxiety (GAD-7), depression (PHQ-9), quality-of-life (QOL) (CQLI-R), and self-rated health and energy were reported prior to interviews.

RESULTS

Qualitative analysis revealed three themes: compromised sleep quality, factors influencing sleep, effects of sleep. 72.5% of hospice family caregivers described "fair" or "poor" sleep quality, with "interrupted" sleep and frequent night-waking due to "on-call" "vigilance" and anxiety. Negative effects included exhaustion, mental and physical health decline, and reduced caregiver function. Live-in caregivers reported higher mean depression scores (8.4 vs 4.3, p = 0.08), higher mean anxiety scores (7.7 vs 3.3, p = 0.06), and lower mean QOL scores (24.8 vs 33.6, p < 0.001) than live-out caregivers. Anxiety, depression, and QOL worsened as self-reported caregiver sleep quality decreased. Few caregivers had adequate support.

CONCLUSION

End-of-life family caregivers experience disrupted sleep with negative effects and inadequate support. Clinicians must assess sleep, offer sleep interventions, and provide more supports to hospice family caregivers.

Effect of Carnatic raga-Bilahari based music therapy on anxiety, sleep disturbances and somatic symptoms among caregivers of cancer patients

Carnatic raga-Bilahari based intervention is a music therapy technique that enhances relaxation and positivity by reducing anxiety. With extensive empirical evidence pointing out the detrimental challenges faced by the caregivers of cancer patients, the present study intends to find out the effectiveness of a Carnatic raga based music therapy on reducing anxiety, sleep disturbances, somatic symptoms and distress level among this population A single group pre-post research design was was used to conduct the study. General Health Questionnaire (GHQ-28) was used as a screening tool to select participants, and 30 participants were chosen using the purposive sampling. These individuals received instruction in listening to Carnatic music (raga-Bilahari), 5 days a week. The vocal and instrumental recordings were given on alternative days with each session lasting 15–30 min over a month of standard care. From the findings it is observed that there is significant decrease in the anxiety (p < 0.001), sleep disturbances (p < 0.001), somatic symptoms (p < 0.001) and distress level (p < 0.001) after the intervention.The study result thus indicates that Carnatic raga-Bilahari-based music intervention is effective among caregivers of cancer patients to reduce anxiety, sleep disturbances, somatic symptoms presentation, and their distress level.

Sleep quality, anxiety and depression in advanced lung cancer: patients and caregivers

OBJECTIVE

To investigate the clinical implications of sleep quality, anxiety and depression in patients with advanced lung cancer (LC) and their family caregivers (FCs).

METHODS

A total of 98 patients with advanced LC and their FCs (n=98) were recruited from the Oncology Department in Nanfang Hospital. The Pittsburgh Sleep Quality Index (PSQI), consisting of seven components that evaluate subjective sleep quality, sleep latency, duration of sleep, sleep efficiency, sleep disturbances, sleep medication usage and daytime dysfunction, was used to assess sleep quality. Using the tool of Zung Self-rating Anxiety Scale (SAS) and Zung Self-rating Depression Scale (SDS), we tested the patients' status of anxiety and depression, respectively.

RESULTS

The prevalences of poor sleep quality, anxiety and depression in patients were 56.1%, 48.9% and 56.1%, respectively, while those in FCs were 16.3%, 32.6% and 25.5%, respectively. Patients had higher PSQI, SAS and SDS scores than did FCs (p<0.05). Significant correlations were found between the patients' and FCs' scores of PSQI/SAS/SDS (p<0.05). Multivariate Cox regression analyses indicated that sleep disturbances in patients (HR 0.413, 95% CI 0.21 to 0.80, p=0.01) and the global PSQI score of FCs (HR 0.31, 95% CI 0.14 to 0.71, p=0.00) were independent risk factors for patients' first-line progression-free survival (PFS). Moreover, patients' sleep latency (HR 2.329, 95% CI 1.36 to 3.96, p=0.00) and epidermal growth factor receptor mutations (HR 1.953, 95% CI 1.12 to 3.38, p=0.01) were significant prognostic factors for their overall survival (OS).

CONCLUSIONS

We demonstrated that presence of sleep disturbances in patients with advanced LC and the global PSQI Score of their FCs may be risk predictors for patients' poor first-line PFS. Patients' sleep latency was a potential risk factor for their OS.

Needs assessment instruments for family caregivers of cancer patients receiving palliative care: a systematic review

PURPOSE

Family caregivers of palliative cancer patients experience various supportive care needs. Appropriate self-reported instruments with robust psychological properties are required to identify these needs of family caregivers. Therefore, we conducted a systematic review to identify self-reported supportive care needs assessment instruments for family caregivers of palliative cancer patients and assess their contents, psychometric properties, and applicability.

METHODS

Systematic searches were conducted in six English databases and four Chinese databases from inception to October 2020 and updated in June 2021. The instruments identified were evaluated using an 18-item checklist consisting of six domains: conceptual model, content validity, reliability, construct validity, scoring and interpretation, and respondent burden and presentation.

RESULTS

Six articles, describing four self-reported needs assessment instruments, were included in the review. These instruments varied significantly in terms of contents, constructs, scoring methods, and applicability. Three of these instruments were developed to assess the comprehensive supportive care needs of family caregivers, while one was specifically developed to assess the spiritual needs of family caregivers. With respect to psychometric properties, none of the instruments identified met all the criteria. Three major shortcomings were identified, namely, lack of longitudinal validity, lack of a strategy for interpreting missing data, and lack of a description of the literacy level required to understand the questions. Additionally, the instrument development processes assessed in this study lacked qualitative elements.

CONCLUSIONS

End-users need to consider contents, psychometric properties, and applicability when choosing an appropriate needs assessment instrument according to individual purpose and context. Further evaluation or development of needs assessment for the family caregivers of palliative cancer patients is needed, with a particular emphasis on caregivers' perspectives.

Supporting Family Members in Palliative Phases of Cancer: A Qualitative Study Comparing Health Care Professionals and Non-Health Care Professionals

This comparative and exploratory multicenter study explored the experiences of 2 groups of family members caring for relatives in palliative phases of cancer: caregivers practicing health care professionals (doctors/nurses) and caregivers who were not health care professionals. The ill family members of the 2 groups were also interviewed. Twenty-seven volunteer caregiving relatives (including 16 health professionals) and 18 cancer patients participated in psychologist-conducted semistructured interviews exploring psychological experiences of the support (including daily, personal, and medical care) and, for caregivers, of the interactions with medical teams. Interviews were recorded and transcribed for inductive thematic analysis. Caregiving relatives, irrespective of their profession, all reported developing closer bonds with their relative since the cancer diagnosis and being highly involved in the palliative care. They also all reported psychological stress with additional stress linked to health care professionals' acute knowledge of the disease and treatments often experienced as a burden. Whereas non-health care professional caregivers reported hope for favorable disease progression, health professional caregivers did not. Interactions with the health care team were generally described as satisfactory. A minority of health care professional caregivers reported difficulties when the health care team perceived their investment in the patient's care as negative. Patients' perceptions were consistent with caregiver perceptions.

Sleep, depression, and anxiety in family caregivers of nasopharyngeal carcinoma patients before therapy

Sleep disturbance, anxiety, and depression are frequently observed in cancer patients. There have fewer studies about the sleep and emotional status of nasopharyngeal carcinoma (NPC) patient family caregivers (FCs) before treatment. We explored the sleep, depression, and anxiety in NPC patient FCs before therapy, compared sleep quality between caregivers with and without depression and anxiety, and examined and related factors of sleep disturbance in FCs of NPC patients before therapy. FC-patient dyads included from two centers were 92 in total. The proportions of poor sleep, anxiety, and depression in NPC patient FCs were 45.7%, 43.5%, and 54.3%, respectively. FCs with anxiety or depression were more inclined to report decreased sleep quality. Depressed caregivers were 11.11 times more to be poor quality sleep before patients treatment (OR = 11.11, 95%; CI = 2.94-42.05). NPC patient FCs before treatment are at high risk of sleep disturbances, depression, and anxiety, especially those already experiencing anxiety and depression symptoms.

The influence of symptom severity of palliative care patients on their family caregivers

Background

This study anlyzed whether family caregivers of patients with advanced cancer suffer impaired sleep quality, increased strain, reduced quality of life or increased care burden due to the presence and heightened intensity of symptoms in the person being cared for.

Method

A total of 41 patient-caregiver dyads (41 caregivers and 41 patients with advanced cancer) were recruited at six primary care centres in this cross-sectional study. Data were obtained over a seven-month period. Caregiver’s quality of sleep (Pittsburgh Sleep Quality Index), caregiver’s quality of life (Quality of Life Family Version), caregiver strain (Caregiver Strain Index), patients’ symptoms and their intensity (Edmonton Symptom Assessment System), and sociodemographic, clinical and care-related data variables were assessed. The associations were determined using non-parametric Spearman correlation.

Results

Total Edmonton Symptom Assessment System was significantly related to overall score of the Pittsburgh Sleep Quality Index (r = 0.365, p = 0.028), the Caregiver Strain Index (r = 0.45, p = 0.005) and total Quality of Life Family Version (r = 0.432, p = 0.009), but not to the duration of daily care (r = -0.152, p = 0.377).

Conclusions

Family caregivers for patients with advanced cancer suffer negative consequences from the presence and intensity of these patients’ symptoms. Therefore, optimising the control of symptoms would benefit not only the patients but also their caregivers. Thus, interventions should be designed to improve the outcomes of patient-caregiver dyads in such cases.

Development and palliative care staff reactions to a sleep regulation educational intervention

Background

In palliative care, sleep and circadian rhythm problems are common symptoms. Nonpharmacological interventions are available; however, health care providers are not aware of these or lack the knowledge to effectively implement in practice. This study reports the content and design development of the PRIME™ (Program for Improving & Managing Environments for Sleep) sleep online educational intervention as well as the evaluation of the intervention by practicing nurses with a focus on perceived acceptability and satisfaction.

Methods

Development of the education employed a multi-step process that assesses the current state of the science in this area (literature reviews), the needs of regional target recipients (hospice/palliative care staff), expert recommendations and views of a national pool of hospice/palliative workers. A cross-sectional, descriptive study with key staff informants evaluated the acceptability and usability of the modules using both scale-response items to rate the content and design of the modules and overall satisfaction and five open-response questions to suggest changes to the educational intervention.

Results

Among 31 palliative care professionals, most rated the content and design favorably. A total of 20 participants provided suggestions to improve the educational intervention. Their comments were categorized into six themes: Integration into Practice; Content, Exercises and Material Provided by Modules; User Interface and Design; and Adapt and Expand Modules for Public, Family and Caregivers.

Conclusions

The data suggest that the PRIME™ educational intervention can be an effective tool to train direct-care palliative care professionals on interventions for use in their daily practice. We also demonstrated that the educational intervention is feasible to deliver online and that the online modules appealed to respondents, suggesting that future delivery of the educational intervention can use the same or similar modes of presentation.

Symptom distress and quality of life among Black Americans with cancer and their family caregivers

OBJECTIVE

Black Americans are disproportionately affected by cancer and chronic diseases. Black patients with cancer and their family caregivers may concurrently experience symptoms that influence their wellbeing. This study investigates the influence of mental and physical symptom distress on quality of life (QOL) among Black Americans with cancer and their family caregivers from a dyadic perspective.

METHODS

One hundred and fifty-one dyads comprised of a Black American with breast, colorectal, lung or prostate cancer and a Black family caregiver were included in this secondary analysis of pooled baseline data from three studies. Self-reports of problems managing 13 symptoms were used to measure mental and physical symptom distress. Descriptive statistics and the actor-partner interdependence model were used to examine symptom prevalence and the influence of each person's symptom distress on their own and each other's QOL.

RESULTS

Fatigue, sleep problems, pain and mental distress were prevalent. Patients and caregivers reported similar levels of mental distress; however, patients reported higher physical distress. Increased patient mental distress was associated with decreased patient QOL (overall, emotional, social, functional). Increased patient physical distress was associated with decreased patient QOL (overall, physical, emotional, functional) and decreased caregiver emotional wellbeing. Increased caregiver mental distress was associated with decreased caregiver QOL (overall, emotional, social, functional) and decreased patient overall QOL. Increased caregiver physical distress was associated with decreased caregiver QOL (overall, physical, functional), decreased patient emotional wellbeing, and better patient social wellbeing.

CONCLUSIONS

Supporting symptom management in Black patient/caregiver dyads may improve their QOL.

Check your sleep before you start: A secondary analysis of a stress management intervention for caregivers of stem cell transplant patients

OBJECTIVE

Caregiving for hematopoietic stem cell transplant (HSCT) patients is associated with significant physical and psychological sequelae. While psychosocial interventions may reduce caregiver burden, knowledge regarding which caregivers may benefit the most from such interventions is limited. The purpose of this secondary analysis was to examine whether HSCT caregivers' peritransplant sleep moderated the effect of a psychosocial intervention on depression and anxiety posttransplant.

METHODS

Participants included 135 caregivers (mean age = 54.23) who participated in randomized controlled trial and were assigned to receive either 8 weeks of Psychoeducation, Paced Respiration, and Relaxation (PEPRR) or treatment as usual (TAU). Sleep, depression, and anxiety were assessed using the Pittsburg Sleep Quality Index, the Center for Epidemiologic Studies Depression Scale, and the State-Trait Anxiety Inventory, respectively. Caregiver symptoms were assessed at baseline (e.g., peritransplant period) and 6-month posttransplant.

RESULTS

Baseline sleep quality (∆R²  = 0.04, p = 0.002), sleep efficiency (∆R²  = 0.03, p = 0.02), and sleep onset latency (∆R²  = 0.07, p < 0.001) independently moderated the effect of group assignment on depression outcomes at the 6-month follow-up. Specifically, caregivers with poor sleep at baseline who received PEPRR reported significantly lower depression scores at follow-up compared to caregivers with poor sleep who received TAU. By contrast, only sleep quality (∆R²  = 0.02, p = 0.01) and sleep onset latency (∆R²  = 0.02, p = 0.005) moderated the effect of the group assignment on anxiety.

CONCLUSIONS

Psychosocial interventions for HSCT caregivers may buffer against psychological morbidity, particularly among caregivers with poor sleep quality.

Interventions that Improve Sleep in Caregivers of Adult Care-Recipients: A Systematic Review

The purpose of the present review was to compile and analyze all interventions aimed at improving the sleep-rest pattern of adult caregivers. A database search was performed in PubMed, Embase, Scopus, CINAHL and PsycINFO. Twenty-four papers published between 1998 and 2020 met the inclusion criteria. Informal caregivers can benefit from various types of sleep interventions, including (a) cognitive-behavioral sleep interventions (CBIs), (b) caregiver health interventions (CHIs), and (c) exercise programs. Other types of interventions such as acupressure, back massage, reflexology, music, and heart rate variability biofeedback sessions may have beneficial effects on the sleep of caregivers. Yet, studies on this topic are heterogeneous and often have considerable methodological shortcomings. Few clinical trials have explored sleep problems as a dyadic caregiver-patient relationship. It is necessary to conduct new clinical trials to determine the viability and level of evidence of the various strategies aimed at improving sleep of informal caregivers.

Predictors of sleep disturbances in caregivers of patients with advanced cancer receiving home palliative care: A descriptive cross-sectional study

PURPOSE

To evaluate the quality of sleep in caregivers of patients with advanced cancer receiving home palliative care, basing the analysis on subjective and objective measures, and to develop a predictive model of sleep disturbances among this population.

METHOD

A descriptive cross-sectional study was conducted in six clinical management units within primary healthcare centres. Data were obtained during a period of six months, from a sample population of 41 caregivers. The Pittsburgh Sleep Quality Index (PSQI) and a 7-day accelerometry evaluation were performed to assess sleep quality. Daytime sleepiness, caregiver strain and quality of life were also evaluated.

RESULTS

According to the PSQI, 90.2% of participants had poor sleep quality. The average duration of night-time sleep, measured by accelerometry and the PSQI, was 6 h. Taking PSQI as the dependent variable, the study model predicted 40.7% of the variability (p < 0.01). The variables "Caregiver strain" and "Daily hours dedicated to care" produced the following results: B coefficient 0.645; p = 0.001; and B coefficient 0.230; p = 0.010, respectively.

CONCLUSIONS

The caregivers presented significant health-related alterations, including sleep disturbances, which were directly related to two variables: the index of caregiver strain and the number of hours per day dedicated to providing care.

Intervention to improve quality of sleep of palliative patient carers in the community: protocol for a multicentre randomised controlled trial

BACKGROUND

Sleep disorders are commonly experienced by community caregivers for persons with cancer, with at least 72% reporting moderate to severe disorders. A consequence of this condition, which is associated with the presence of overload in the caregiver, is the increased risk of clinical depression. The aim of this study is to evaluate the effects of music on the sleep quality achieved by informal caregivers for cancer patients receiving home palliative care. In addition, we will assess the influence of specific variables that could modify these effects, analyse the correlates related to nocturnal wakefulness and consider the diurnal consequences according to the sleep characteristics identified.

METHODS

This single-blind, multicentre, randomised clinical trial will focus on informal providers of care for cancer patients. Two samples of 40 caregivers will be recruited. The first, intervention, group will receive seven music-based sessions. The control group will be masked with seven sessions of therapeutic education (reinforcing previous sessions). Outcomes will be evaluated using the Pittsburgh Sleep Quality Index, a triaxial accelerometer, EuroQol-5D-5L, the Caregiver Strain Index, the Epworth Sleepiness Scale and the Client Satisfaction Questionnaire. The caregivers' satisfaction with the intervention performed will also be examined.

DISCUSSION

This study is expected to extend our understanding of the efficacy of music therapy in enhancing the sleep quality of caregivers for patients receiving home palliative care. To our knowledge, no reliable scientific investigations of this subject have previously been undertaken. Music is believed to benefit certain aspects of sleep, but this has yet to be proven and, according to a Cochrane review, high-quality research in this field is necessary. One of the main strengths of our study, which heightens the quality of the randomised clinical trial design, is the objective assessment of physical activity by accelerometry and the use of both objective and subjective measures of sleep in caregivers. Music therapy for the caregivers addressed in this study is complementary, readily applicable, provokes no harmful side effects and may produce significant benefits.

Sex-specific and gender-specific aspects in patient-reported outcomes

Patient-reported outcomes (PROs) are important tools in patient-centred medicine and allow for individual assessment of symptom burden and aspects of patients’ quality of life. While sex and gender differences have emerged in preclinical and clinical medicine, these differences are not adequately represented in the development and use of patient-reported outcome measures. However, even in personalised approaches, undesirable biases may occur when samples are unbalanced for certain characteristics, such as sex or gender. This review summarises the current status of the literature and trends in PROs with a focus on sex and gender aspects.

Effectiveness of Self-administered Acupressure for Family Caregivers of Advanced Cancer Patients With Insomnia: A Randomized Controlled Trial

BACKGROUND

Sleep disturbances are common among family caregivers (FCs) of patients with advanced cancer. Self-administered acupressure can combat insomnia, but no study has been conducted to evaluate its efficacy in caregivers of patients with advanced cancer.

OBJECTIVE

The aim of this study is to investigate whether self-administered acupressure improves sleep quality for FCs of patients with advanced cancer.

METHODS

Family caregivers of patients with advanced cancer who reported sleep disturbance (Pittsburgh Sleep Quality Index scores >5 in recent months) were recruited. The experimental group self-administered acupressure at the Baihui (GV20), Fengchi (GB20), Neiguan (PC6), and Shenmen (HT7) points over a 12-week period, whereas the comparison group received sleep hygiene education. Sleep quality was assessed subjectively at 4, 8, and 12 weeks after the intervention using the Pittsburgh Sleep Quality Index and objectively using actigraphy measurements. Improvements in sleep quality were analyzed using a generalized estimating equation.

RESULTS

Compared with the control group, the experimental group demonstrated significantly lower sleep latency (Wald χ2 = 11.49, P = .001) and significantly better sleep efficiency (Wald χ2 = 5.24, P = .02) according to actigraphy measurements, but Pittsburgh Sleep Quality Index scores did not differ significantly between the groups.

CONCLUSIONS

Self-administered acupressure did not demonstrate favorable effects on subjective sleep quality, but did reduce sleep latency and improve sleep efficiency, according to actigraphy measurements. Self-administered acupressure may help relaxation and sedation and promote sleep in FCs.

IMPLICATIONS FOR PRACTICE

Healthcare providers may consider advising FCs to apply this self-administered acupressure to improve their sleep latency and sleep efficiency.

Sleep problems in advanced cancer patients and their caregivers: Who is disturbing whom?

Background The aims of the study were to understand sleep problems and their effects in advanced cancer patients and spousal and intimate partner caregivers and to examine the directionality of the link between patients' and caregivers' sleep problems. Methods Fifty-four advanced cancer patients and their spousal and intimate partners were administered a battery of questionnaires that included the Pittsburgh Sleep Quality Index and the Center for Epidemiological Studies at the patients' cancer diagnosis and at 2, 4, and 6 months after diagnosis. Results Patients' and caregivers' sleep duration was significantly related. Using cross-lagged panel analyses, caregivers' sleep quality significantly predicted patients' sleep quality and patients' sleep quality subsequently predicted caregivers' sleep quality. Patients' sleep latency significantly was found to significantly predict caregivers' sleep latency. Conclusion Patients diagnosed with cancer and their intimate partners have poor sleep quality and sleep patterns are related.

Concomitant Benefits of an Auricular Acupressure Intervention for Women With Cancer on Family Caregiver Sleep Quality

BACKGROUND

Sleep disturbance is a frequent and significant problem challenge for family caregivers of patients with cancer. A previously tested 6-week auricular acupressure intervention was found to reduce symptom burden in women with cancer. It is possible that such an intervention has a concomitant benefit for family caregivers.

OBJECTIVES

The aim of this study was to explore if the effects of an auricular acupressure intervention on major symptoms experienced by women with ovarian cancer improves the sleep quality of family caregivers.

METHODS

A quasi-randomized controlled trial with a repeated-measures design was used. Family caregivers (n = 68) of cancer patients were recruited and completed the Pittsburgh Sleep Quality Index on 4 occasions. Demographic information included age, sex, duration of caring role, and relationship to the patient.

RESULTS

Family members with a longer duration of caregiving reported more sleep disturbance at baseline. As the symptom burden of treated women decreased, their family caregivers reported improved Pittsburgh Sleep Quality Index scores at 4 weeks (time 2; Cohen d = 1.075) and 6 weeks (time 3; Cohen d = 1.022).

CONCLUSIONS

Reducing the symptom burden of patients with cancer can improve the sleep quality of family caregivers.

IMPLICATIONS FOR PRACTICE

Auricular acupressure is a noninvasive and easy-to-apply intervention that can be applied by caregivers to assist their family member. Nursing staff can implement and test the acupressure intervention into their clinical practice and better support family-based strategies and interventions. Further studies with larger samples are needed to confirm our findings.

Caregiving burden and sleep quality amongst family caregivers of Chinese male patients with advanced cancer: A cross-sectional study

PURPOSE

To examine the level of caregiving burden and sleep quality as well as their interrelationship amongst family caregivers of Chinese male patients with advanced cancer.

METHOD

A cross-sectional study was conducted in Hong Kong. The Caregiver Reaction Assessment (CRA) and the Pittsburgh Sleep Quality Index (PSQI) were used to measure caregiving burden and sleep quality of the family caregivers.

RESULTS

A total of 96 family caregivers were recruited. Disrupted schedule (3.8; SD = 0.8) was rated as the most affected consequence of caregiving burden. Around 78.1% of the caregivers suffered from sleep problems. Hierarchical multiple regression revealed that health problems due to caregiving burden was independently associated with poor sleep quality after controlling for socio-demographic characteristics of both patients and caregivers (regression coefficient, B = 2.09, P = 0.012).

CONCLUSIONS

Caregiving burden amongst family caregivers of male patients with advanced cancer was remarkably high and associated with poor sleep quality. Strategies aiming to alleviate caregiving burden of caregivers may help break this vicious cycle to enhance the sleep quality of caregivers. Results also underscore the need to assess and develop intervention to relieve caregiving burden for family caregivers of cancer patients.

Complementary music therapy for cancer patients in at-home palliative care and their caregivers: protocol for a multicentre randomised controlled trial

Background

Patients with advanced cancer, receiving at-home palliative care, are subject to numerous symptoms that are changeable and often require attention, a stressful situation that also impacts on the family caregiver. It has been suggested that music therapy may benefit both the patient and the caregiver. We propose a study to analyse the efficacy and cost utility of a music intervention programme, applied as complementary therapy, for cancer patients in palliative care and for their at-home caregivers, compared to usual treatment.

Method

A randomised, double-blind, multicentre clinical trial will be performed in cancer patients in at-home palliative care and their family caregivers. The study population will include two samples of 40 patients and two samples of 41 caregivers. Participants will be randomly assigned either to the intervention group or to the control group. The intervention group will receive a seven-day programme including music sessions, while the control group will receive seven sessions of (spoken word) therapeutic education. In this study, the primary outcome measure is the assessment of patients’ symptoms, according to the Edmonton Symptom Assessment System, and of the overload experienced by family caregivers, measured by the Caregiver Strain Index. The secondary outcomes considered will be the participants’ health-related quality of life, their satisfaction with the intervention, and an economic valuation.

Discussion

This study is expected to enhance our understanding of the efficacy and cost-utility of music therapy for cancer patients in palliative care and for their family caregivers. The results of this project are expected to be applicable and transferrable to usual clinical practice for patients in home palliative care and for their caregivers. The approach described can be incorporated as an additional therapeutic resource within comprehensive palliative care. To our knowledge, no previous high quality studies, based on a double-blind clinical trial, have been undertaken to evaluate the cost-effectiveness of music therapy. The cost-effectiveness of the project will provide information to support decision making, thereby improving the management of health resources and their use within the health system.

Effect of Heart Rate Variability Biofeedback Sessions With Resonant Frequency Breathing on Sleep: A Pilot Study Among Family Caregivers of Patients With Cancer

Heart rate variability biofeedback (HRV-BF) is used as a skill in psychosomatic medicine, but is not yet established in the field of sleep. The present study aimed to evaluate the effect of HRV-BF with resonant frequency breathing (RFB) on sleep performed once every 2 weeks and the usefulness of practice of RFB using a portable device at home before bedtime. Participants were 69 family caregivers of patients with cancer that felt burdened by nursing care. We conducted a randomized controlled trial with an HRV-BF+Home practice group and an HRV-BF group. HRV-BF with RFB was administered to both groups at our medical institution for up to 30 min on the experiment days. Home practice involved RFB using a portable device, which was performed at home each day within 20 min before bedtime. Evaluation items were: change ratio of total score of the Pittsburgh Sleep Quality Index (PSQI) at 28 days after the trial started. In total, 52.2% of participants had insomnia. The two HRV-BF groups had decreased PSQI total scores, which indicated an improvement in PSQI total score near 5.5 on Day 28. The two HRV-BF groups had significantly increased HRV scores on Day 28, and there was correlation between the variation of PSQI total score and the variation of HRV score. The quality of sleep assessed by PSQI scores in the HRV-BF+Home practice group was significantly improved compared with the HRV-BF group on Day 28 (p = 0.001). This suggests HRV-BF may be a useful skill for enhancing sleep among family caregivers of patients with cancer, as well as supporting their autonomic nervous function. Additional actual regular practice of RFB (using a portable device at home before bedtime) may further enhance the effect.

From bystander to enlisted carer - A qualitative study of the experiences of caregivers of patients attending follow-up after curative treatment for cancers in the pancreas, duodenum and bile duct

PURPOSE

Caregivers of patients with cancer play an important role throughout the treatment trajectory. This can be challenging and might infer health and psychosocial problems. This may especially be the case in caregivers of patients with cancers that carry a high risk of recurrence such as cancers of the pancreas, duodenum and bile duct. This study therefore explored the experiences of caregivers of patients attending follow-up after completion of treatment with curative intent for cancers of the pancreas, duodenum and bile duct.

METHODS

A qualitative study using semi-structured, individual interviews. Data were analysed using content analysis.

RESULTS

Ten caregivers of patients attending follow-up after completed curative treatment for cancers of the pancreas, duodenum and bile duct in a specialized gastro-surgical center at a tertiary hospital in the Capital Region of Denmark participated. We identified three themes: "From bystander to enlisted carer", inferring that caregivers felt enlisted as carers during treatment and follow-up, however without sufficient instruction or assessment of their needs. "Lonesome worrying" meaning that caregivers hid their feelings of concern and foreboding, and finally, "Keeping a stiff upper lip" indicating that caregivers outwardly maintained a positive face when interacting with the patient.

CONCLUSION

Caregivers described taking on a substantial burden of care without feeling competent. They experienced distress and emotional isolation which affected their relationship with the patient and their mutual coping. The results indicate a need for health care professionals to facilitate reflection on the needs and roles of both patients and caregivers throughout the treatment trajectory.

The Psychobiology of Bereavement and Health: A Conceptual Review From the Perspective of Social Signal Transduction Theory of Depression

Losing a spouse is considered one of the most stressful life events a person can experience. Particularly in the immediate weeks and months after the loss, bereavement is associated with a significantly increased risk of morbidity and mortality. Despite an abundance of research aimed at identifying risk factors for adverse health outcomes following marital death, the mechanisms through which mental and physical health problems emerge following bereavement remain poorly understood. To address this issue, the present review examines several pathways that may link bereavement and health, including inflammation and immune dysregulation, genetic and epigenetic changes, gut microbiota activity, and biological aging. We then describe how these processes may be viewed from the perspective of the Social Signal Transduction Theory of Depression to provide a novel framework for understanding individual differences in long-term trajectories of adjustment to interpersonal loss. Finally, we discuss several avenues for future research on psychobiological mechanisms linking bereavement with mental and physical health outcomes.

Dyadic effects of distress on sleep duration in advanced cancer patients and spouse caregivers

OBJECTIVE

Short sleep duration is a common problem for both advanced cancer patients and their spouse caregivers. Sleep and distress have been shown to be interdependent in patient-caregiver and spouse dyads, yet virtually, no work has explored the dyadic effects of psychological distress on sleep in advanced cancer patients and spouse caregivers. The goal of the present study was to examine the dyadic impact of anxiety and depression on sleep duration in a sample of advanced cancer patients and their spouse caregivers. It was hypothesized that, for both patients and caregivers, anxiety and depression in individuals would be associated with sleep duration in both themselves (actor effects) and in their spouses (partner effects).

METHOD

Advanced cancer patients and their spouse caregivers (N = 87 dyads) completed cross-sectional questionnaires assessing demographic variables, subjective health, subjective sleep duration, and anxiety and depression symptoms.

RESULTS

Controlling for sex, age, and subjective health, individuals' anxiety was negatively associated with their own and their partner's sleep duration. No significant actor or partner effects were found for depression.

CONCLUSIONS

Results provided partial support for hypotheses. Although past work has demonstrated links between subjective sleep disturbance and anxiety/psychological distress, this is one of the first studies to examine partner effects of distress on sleep disturbance in advanced cancer patients and spouse caregivers.

Sleep problems in advanced disease

Sleep problems are relatively common in patients with advanced disease, and are associated with significant morbidity in these groups of patients. The focus of this article is sleep problems in patients with advanced cancer, and specifically insomnia, 'vivid' dreams and nightmares. However, other sleep problems are also relatively common in this group of patients, including sleep-related breathing disorders and circadian rhythm sleep-wake disorders. Healthcare professionals should screen all patients with advanced diseases for sleep problems and, equally, initiate appropriate (evidence-based) interventions when they are discovered.

Role of poor sleep in determining distress in caregivers of individuals with early psychosis

AIM

Looking after someone in the early stages of psychosis can have a negative impact on caregivers, but there is little clarity about which interventions, if any, caregivers should be offered. This study investigated sleep disturbances in early psychosis caregivers and the relationship between their sleep quality and distress.

METHOD

In all, 79 caregivers of patients with a recent first episode of psychosis completed self-report measures including the Pittsburgh Sleep Quality Index (PSQI), the RAND 36-item Health Survey 1.0 (SF-36) and the Experiences of Caregiving Inventory (ECI).

RESULTS

All caregivers were living with their relatives with psychosis and had been providing support since the onset of illness (mean duration = 92.5 weeks, SD = 84.0); 60% (47/79) obtained a global PSQI score that exceeded the established cut-off score for clinically significant sleep problems (>5). Low "sleep duration" and "sleep disturbances" contributed the most to elevated PSQI scores, with 17.7% of participants reporting regular wakening at night due to "stress" or "worries." When predicting psychological distress (SF-36) from negative appraisals of caregiving (ECI) and poor sleep (PSQI), a significant unadjusted regression model was obtained, F(2,73) = 29.440, P = .000, R² of .447. An estimation of the indirect effect of negative thoughts about caregiving on mental distress through poor sleep was also significant (ab = -.05, 95% CI [-.09, -.02], P_M  = .39).

CONCLUSION

Caregivers of people with psychosis may have significant problems with sleep, which relates to distress and negative appraisals about caregiving. Health services need to ask caregivers directly about such issues and consider offering brief interventions to improve sleep quality.

Impact of Penny Brohn UK's Living Well Course on Informal Caregivers of People with Cancer

OBJECTIVES

This study evaluated the change in the concerns, wellbeing, and lifestyle behaviors of informal caregivers of people with cancer attending Penny Brohn UK's Living Well Course (LWC), a self-management education intervention.

DESIGN

A pre-postcourse design collected self-reported quantitative and qualitative data from informal caregivers attending a LWC.

SETTING/LOCATION

Penny Brohn UK is a United Kingdom-based charity (not-for-profit) providing specialist integrative, whole person support, free of charge, to people affected by cancer.

SUBJECTS

Informal caregivers taking part in a Penny Brohn UK LWC between June 2014 and May 2016 attending alongside the person with cancer.

INTERVENTION

The LWC is a structured 15 h, multimodal group self-management educational course, designed to help people affected by cancer learn tools and techniques to help build resilience. Trained facilitators deliver LWCs to around 12 people with various types and stages of cancer and their informal caregivers.

OUTCOME MEASURES

Measure Yourself Concern and Wellbeing (MYCaW) completed precourse and at 6 weeks postcourse; and bespoke 6-week follow-up Patient Reported Experience Measure.

RESULTS

Four hundred eighty informal caregivers attended a LWC June 2014 to May 2016. One hundred eighteen completed a 6-week follow-up MYCaW: MYCaW Concerns 1 and 2 showed statistically significant improvements (p < 0.0001), there was no significant improvement in wellbeing. Informal caregivers' most reported concerns relating to themselves were psychological and emotional issues (59%). The primary concern of the caregiver for the care recipient was related to the physical health of the person with cancer (40%). Eighty-seven percent of responding informal caregivers stated that the LWC enabled health self-management.

CONCLUSIONS

The LWC was followed by an improvement in informal caregivers' concerns, and increased self-management of their own health needs. More studies, with larger sample size, are needed to explore if better self-management by informal caregivers may also lead to improvements in patients' health and wellbeing.

Whole body vibration exercise in the management of cancer therapy-related morbidities: A systematic review

The purpose of this systematic review was to investigate the effects of whole body vibration (WBV) exercise in the management of cancer therapy-related morbidities. The PubMED and PEDro databases were used to access publications published in English about the use of whole body vibration (WBV) exercises in cancer patients until February 22^nd 2017. The studies included were classified according to the level of evidence (LE) by the National Health and Medical Research Council Hierarchy of evidence and the methodological quality (MQ) by the PEDro scale. The four included studies (2 of them with "high" LE-II and MQ) were performed in patients with different types of cancer (i.e. breast, lung, prostate, solid or hematological), treated with WBV exercise to counteract the cancer therapy-related morbidities. The variables evaluated were muscle activity, subjective rate of perceived exertion, exercise capacity, muscle strength, quality of life, resting urinary incontinence and severity of peripheral neuropathy. Although WBV exercise appears to be a potential treatment procedure of cancer therapy-related morbidities, further additional studies are required to determine specific and tailored protocols to be used in the different stages of the disease.

Sleep Pattern and Predictors of Sleep Disturbance Among Family Caregivers of Terminal Ill Patients With Cancer in Taiwan: A Longitudinal Study

Background:

Sleep disturbance commonly has a negative impact on the well-being of family caregivers (FCs) of terminally ill patients with cancer. The effect of sleep disturbance on FCs has not been explored through long-term follow-up studies in Taiwan.

Objective:

The purposes of this study were to (1) identify the trajectory of sleep quality of FCs of terminally ill patients with cancer in Taiwan and (2) examine the determinants of sleep disturbance through a longitudinal follow-up until patient death.

Methods:

A prospective, longitudinal study was conducted among 95 FCs of terminally ill patients with cancer. The FCs’ sleep quality was measured subjectively by using the Pittsburgh Sleep Quality Index and objectively by wearing a wrist actigraphy for 48 hours each month during the 6-month follow-up assessments. The trajectory and determinants of sleep quality were identified using a generalized estimation equation approach.

Results:

The FCs’ sleep quality significantly decreased as the patient’s death approached. Family caregivers who were women or older, had a relative with a longer survival period after diagnosis, reported higher levels of depression and fatigue, and provided lower levels of assistance to their relatives experienced more sleep disturbance.

Conclusion:

The sleep quality of Taiwanese FCs significantly deteriorated as the death of the terminally ill patients with cancer approached. Early detection of the FCs’ sleep disturbance, increasing their self-awareness of sleep problems, and providing nonpharmacological interventions and psychosocial support may be helpful for FCs to improve their quantity and quality of sleep.

Informal Care and Sleep Disturbance Among Caregivers in Paid Work: Longitudinal Analyses From a Large Community-Based Swedish Cohort Study

STUDY OBJECTIVES

To examine cross-sectionally and prospectively whether informal caregiving is related to sleep disturbance among caregivers in paid work.

METHODS

Participants (N = 21604) in paid work from the Swedish Longitudinal Occupational Survey of Health. Sleeping problems were measured with a validated scale of sleep disturbance (Karolinska Sleep Questionnaire). Random-effects modeling was used to examine the cross-sectional association between informal caregiving (self-reports: none, up to 5 hours per week, over 5 hours per week) and sleep disturbance. Potential sociodemographic and health confounders were controlled for and interactions between caregiving and gender included. Longitudinal random-effects modeling of the effects of changes in reported informal caregiving upon sleep disturbance and change in sleep disturbance was performed.

RESULTS

In multivariate analyses controlling for sociodemographics, health factors, and work hours, informal caregiving was associated cross-sectionally with sleep disturbance in a dose-response relationship (compared with no caregiving, up to 5 hours of caregiving: β = 0.03; 95% CI: 0.01, 0.06, and over 5 hours: β = 0.08; 95% CI: 0.02, 0.13), results which varied by gender. Cessation of caregiving was associated with reductions in sleep disturbance (β = -0.08; 95% CI: -0.13, -0.04).

CONCLUSIONS

This study provides evidence for a causal association of provision of informal care upon self-reported sleep disturbance. Even low-intensity care provision was related to sleep disturbance among this sample of carers in paid work. The results highlight the importance of addressing sleep disturbance in caregivers.

Propiedades psicométricas del cuestionario general del salud de Goldberd – QHQ-28 – en cuidadores primarios informales de pacientes con cáncer
