Palliative Care Interventions for Caregivers of People With Advanced Dementia: A Meta‐Analysis

BACKGROUND: Palliative care reduces caregiver burden, alleviates patient symptoms, and supports treatment decision-making. However, despite these benefits, there is limited evidence on the effectiveness of palliative care interventions for caregivers of individuals with advanced dementia. AIMS: To integrate and analyze data on the effectiveness of palliative care interventions in improving caregiver outcomes in order to ensure that both patients and caregivers receive the support necessary for optimal care experiences, quality of life management, and advanced care planning. METHODS: A systematic search was conducted of six databases to identify relevant studies published from database inception to 12 December 2024. Randomized controlled trials (RCTs) investigating palliative care interventions for caregivers of people with advanced dementia were included. Version 2 of the Cochrane Risk of Bias tool was used to assess the risk of bias in the methodology of each study. Standardized mean differences (SMDs) between each intervention and control group were calculated. A random-effects DerSimonian and Laird model was applied to generate pooled SMD estimates for each outcome and assess its heterogeneity. A leave-one-out sensitivity analysis was performed to ensure the stability of the pooled effect sizes. FINDINGS: Eight RCTs were included in the final analysis. Palliative care interventions appeared to reduce conflict in decision-making among caregivers of people with advanced dementia. CONCLUSION: Palliative care interventions were successful in reducing conflict in decision-making of caregivers of people with advanced dementia. However, the modality's effects on caregiver satisfaction and caregiver distress need further investigation. LINKING EVIDENCE TO ACTION: Future palliative care interventions for caregivers of advanced dementia patients should focus on developing the contents of palliative care materials based on evidence-based evaluations and explore strategies to improve engagement between patients, caregivers, and healthcare professionals.
