Determinants of Caregiver Burden Among Spouses of Patients With Kidney Failure: A Qualitative Study.

Rationale & Objective: Spousal caregivers participate extensively in the care of patients with kidney failure. Although previous studies suggested that these caregivers experience a high burden, a comprehensive understanding of the determinants of this burden and strategies to alleviate it are needed. Therefore, this study sought to explore the contributing and alleviating determinants of burden in spousal caregivers of patients with kidney failure.

Study Design: A qualitative interview study with 15 spousal caregivers.

Setting & Participants: Dutch-speaking, adult spousal caregivers were recruited and interviewed by the Dutch Kidney Patients Association for the Kidney Decision Aid.

Analytical Approach: A directed qualitative content analysis using the stress-appraisal model of caregiver burden as a framework to inform a disease-specific model on spousal caregiver burden for kidney failure that characterizes the impact of care provision on all aspects of spousal caregivers' lives, the burden associated with it, and possible mitigating factors.

Results: Providing care for patients with kidney failure is complex and burdensome for spousal caregivers and results in many lifestyle changes, which is largely caused by kidney failure-specific tasks and the shifting responsibility for daily life tasks. Spouses identified disease-specific determinants of burden including the impact of kidney disease on afflicted spouses as well as the associated caregiver tasks, e.g., adjusting to dietary restriction and attending dialysis appointments. Dialysis options (e.g., the choice for home or in-center dialysis) were kidney failure-specific moderators of burden. Support of spousal caregivers by healthcare providers plays a key role in preventing overburdening.

Limitations: Potential limited transferability owing to the study of only Dutch-speaking spouses willing to be interviewed and videotaped.

Conclusions: This comprehensive overview of the contributing and alleviating determinants of burden experienced by spousal caregivers of patients with kidney failure highlights four principal areas; 1) personal and relational, 2) social environment, 3) healthcare, and 4) work and legislation, in which such burdens occur and may be alleviated.
