Abstract
AIMS: To synthesize the qualitative evidence on dyadic relationships between informal caregivers and older adults with chronic heart failure (HF). METHODS AND RESULTS: A systematic review and meta-synthesis were conducted. Eight databases were searched for English peer-reviewed studies and grey literature published from inception to 27 February 2024. Qualitative and mixed-method studies involving older adults ≥55 years old with chronic HF and discussing patient-caregiver relationships in community settings were included. Data were synthesized using Sandelowski and Barroso's two-step framework. A meta-summary was developed using thematic analysis, and findings were synthesized using the Theory of Dyadic Illness Management. Twenty-four studies from 2008 to 2024 were included (n = 580 participants). The meta-summary consisted of four themes and nine subthemes: (i) Characteristics of dyad relationships, (ii) How both parts of the dyad care for each other, (iii) Chronic HF and dyad relationships, and (iv) Knowledge of managing chronic HF. These were reorganized into the meta-synthesis: dyadic appraisal, dyadic management behaviours, dyadic health, contextual factors affecting dyadic relationships and management behaviours, and illness management as a dyadic phenomenon. CONCLUSION: Investigating relationship dynamics and their impact on dyads and chronic HF self-care is vital. Where possible, healthcare providers should prioritize dyadic care when caregivers are involved and deliver individualized care to improve patient and caregiver outcomes. Assessing and optimizing dyadic relations, addressing individual perceptions and needs as part of clinical care, and before implementing self-care interventions in research may help ensure that self-care is appropriately tailored and would not be hindered by relationship conflicts.
