All-Cause Mortality Among Men Whose Cohabiting Partner Has Been Diagnosed with Cancer

Protocol for 'Resilient Caregivers': a randomised trial of a resilience-based intervention for psychologically distressed partner caregivers of patients with cancer

INTRODUCTION

Intimate partners of patients with cancer often experience significant distress, but there is a lack of psychological interventions that specifically target this population. 'Resilient Caregivers' is a novel resilience-based intervention for distressed partner cancer caregivers. The intervention was developed according to a resilience framework focusing on meta-reflective skills, coping strategies and value clarification. The aim of this study is to evaluate the effectiveness of this intervention in a randomised trial.

METHODS AND ANALYSIS

Eighty participants will be invited through the Oncology Department at Herlev Hospital, Denmark and randomised to either the intervention or usual care. Participants are eligible if they are partners (married or unmarried) of patients diagnosed with cancer and experience distress (>4 on the distress thermometer). 'Resilient Caregivers' consists of seven manualised group sessions (2.5 hours each), focusing on resilience in relation to being a partner caregiver of a patient with cancer. The primary outcome is symptoms of anxiety, while secondary outcomes include distress, depression, quality of life, sleep quality and resilience. Data will be collected at baseline, 3, 6 and 12 months follow-up using validated scales, and analysed using mixed models for repeated measures.

ETHICS AND DISSEMINATION

This study will follow the ethical principles in the Declaration of Helsinki and has been reviewed by the Ethics Committee of the Capital Region of Denmark (Journal no. 18055373). Written informed consent will be obtained from all participants. Results will be reported through scientific peer-reviewed journals and relevant conferences.

All-cause mortality for cohabiting spouses of stroke survivors: Evidence from Swedish national registries

BACKGROUND/OBJECTIVES

Spousal concordance for cardiovascular risk factors and lifestyle behaviors may affect prevalence rates of diabetes, hypertension, and stroke. Spouses of stroke survivors, therefore, would be expected to have elevated mortality rates, but this has not been established. Thus, the aim of this study was to investigate whether cohabitant spouses of stroke survivors have higher mortality rates compared to a matched reference cohort.

METHODS

Data for this population-based cohort study were extracted from Swedish national registries from 2010 to 2016. The national sample consisted of 13,049 spouses of first ever stroke survivors and a reference cohort of 51,685 cohabitant individuals from the general population matched by age, gender, and place of residence. Effects on mortality were analyzed using Cox proportional hazard survival analyses.

RESULTS

Female and male spouses of stroke survivors were found to have 5-year hazard ratios of death of 1.26 (95% confidence interval 1.17, 1.36) and 1.24 (95% confidence interval 1.16, 1.33), respectively, when compared to the reference cohort. Both female and male spouses had higher mortality from diseases in the circulatory system compared to the reference cohort.

CONCLUSION

Spouses of stroke survivors have higher mortality rates than a matched reference population that persist for a minimum of 5 years. Policy-makers should acknowledge and address the health status of spouses when evaluating and planning the health and social care of stroke survivors.

Employment transitions for spouses of stroke survivors: evidence from Swedish national registries

BACKGROUND

The sudden occurrence of stroke often leads to impaired physical, emotional, and cognitive abilities. Many stroke survivors therefore require support from their family members. However, little is known about the effects of a stroke event on the spouses' employment transition probabilities. The aim of this study was twofold 1) to investigate whether a first ever stroke has an effect on employment transition probabilities for employed and unemployed spouses and 2) to analyze whether heterogeneity with respect to age, gender, education and comorbidities influence the size of the effect.

METHOD

Data for this population-based cohort study were extracted from Swedish national registries from 2005 to 2016. The national sample consisted of 1818 spouses of first ever stroke survivors during 2010 and 2011, and 7399 matched controls that were employed or unemployed during 5 years prior stroke onset. Effects of stroke on spousal employment transitions were analyzed using linear regression, stratified by employment status prior to stroke onset.

RESULTS

Employed spouses prior stroke onset reduced their employment by - 1.3 percentage points (95% CI, - 2.4, - 0.2). The data also indicated that employed spouses with lower age, comorbid conditions, and low educational attainment may be at even greater risk of transitioning to unemployment. On the other hand, stroke events appear to have limited impact on spouses that were unemployed prior to stroke onset.

CONCLUSION

The risk of transitioning to unemployment appears to increase after stroke onset for spouses of stroke survivors, and disadvantaged groups may be at even greater risk. Thus, it is important for policy-makers to implement interventions to ensure that these groups of spouses have the possibilities to combine their caregiving role and remaining in the labor market.

Spouse's functional disability and mortality: The Ohsaki Cohort 2006 Study

Aim

Caregiver burden is known to negatively affect a partner's health. Given the important role of physical and mental stress in mortality, a higher caregiver burden might be associated with an increased incidence of fatal events. However, previous studies of the effects of the partner's caregiving on mortality have shown inconsistent results. Thus, the purpose of the present longitudinal study was to determine if there is an association between a spouse's functional disability and mortality in the older Japanese population.

Methods

A baseline survey was carried out with 7598 participants in 2006. Information on the date of functional disability, death or emigration was retrieved from the Ohsaki City government. Functional disability was defined as receiving a certification for long‐term care insurance in Japan. After a follow‐up period of a maximum of 87 months, 1316 of the participants died and Cox regression analysis with adjustment for confounding factors was used to assess mortality after the incidence of functional disability in a spouse.

Results

The multivariate adjusted hazard ratio for mortality was 1.78 (95% confidence interval 1.52–2.08, P < 0.01) in those whose spouses had functional disabilities compared with those with spouses who did not have functional disabilities. The mortality was consistently higher, irrespective of age group or sex.

Conclusions

These results imply that caregiver burden might increase stress responses and lead to increased mortality; therefore, enhancement of support systems, including long‐term care, housing and livelihood support services, for those with disability and their spouses might be important for preventing deaths.

All-cause mortality among Japanese whose cohabiting partners are diagnosed with cancer: the Ohsaki Cohort 2006 study

BACKGROUND

It has been noted that not only adverse psychosocial health effects but also mortality might increase for a person living with a spouse with cancer. This study examined the association between a partner's cancer diagnosis and mortality among a Japanese population.

METHODS

In December 2006, a survey was conducted on participants aged 40 years or older who were residing in northeastern Japan. We identified couples using municipality-specific household ID numbers by searching public records and confirmed partner's cancer diagnosis after the baseline measurement using regional cancer registration information. After following up for a maximum of 4.0 years with the participants regarding mortality and emigration by reviewing the Residential Registry Record, we used Cox's proportional hazards regression to estimate the hazard ratio (HR) of all-cause mortality.

RESULTS

We identified 25,938 participants (12,969 pairs) and included them in the analyses. A total of 1,308 (5.0%) participants had partners with a cancer diagnosis after baseline. The study found no association between a partner's cancer diagnosis and all-cause mortality; multivariable HRs of all-cause mortality for individuals in exposed subjects compared with those in unexposed subjects were 1.35 (95% confidence interval [CI] = 0.99-1.83; p = .055). Contrarily, sensitivity analyses of mortality attributed to having partners diagnosed with cancer based on the time since entry showed that all-cause mortality significantly increased only within one year from spouse cancer diagnosis; HR = 2.18 (95% CI = 1.44-3.30; p < .01).

CONCLUSIONS

Our findings reveal that the mortality rate from partner's cancer diagnosis was significantly high during the early period of diagnosis and multidisciplinary teams for cancer treatment might be important for preventing death among the partner.
