Supplementary Material for: Health Economic Analysis on a Psychosocial Intervention for Family Caregivers of Persons with Dementia

<b><i>Background/Aims:</i></b> Psychosocial intervention has shown positive effects on the caregivers' burden and satisfaction. The aims of this study were to describe the cost and cost-effectiveness of such an intervention. <b><i>Methods:</i></b> We analyzed resource use and costs of formal care for 308 persons with dementia and their caregivers' health-related quality of life (HRQoL). <b><i>Results:</i></b> The costs of home help services were lower in the subgroup of spouse caregivers in the intervention group and the cost of nursing home placement was lower in the intervention group. While the person with dementia lived at home, caregivers in the intervention group reported a higher HRQoL (p &lt; 0.01). After the person with dementia had moved to a nursing home, spouses in the control group had a lower HRQoL (p &lt; 0.001). <b><i>Conclusion:</i></b> The result can be interpreted as a positive effect of the intervention focusing on the identified specific needs of the family caregivers.

**背景与目的**：社会心理干预对照料者的负担与满意度已展现出积极作用。本研究旨在阐明该类干预的成本与成本效益情况。
**研究方法**：本研究针对308名痴呆患者及其照料者，分析了正规照护的资源消耗与成本，以及照料者的健康相关生活质量（Health-Related Quality of Life, HRQoL）。
**研究结果**：干预组中配偶照料者亚组的居家辅助服务成本更低，且干预组的养老院入住成本也更低。当痴呆患者居家照护时，干预组照料者自评的健康相关生活质量更高（p < 0.01）。当痴呆患者入住养老院后，对照组的配偶照料者自评的健康相关生活质量更低（p < 0.001）。
**研究结论**：本研究结果可解读为，针对家庭照料者明确的特定需求实施的干预具有积极效果。
