BACKGROUND Besides the importance of estimating the global economic impact of care for persons with dementia, there is an emerging need to identify the key factors associated with this cost. The aim of this study was to analyze associations between the cost of care in community-dwelling persons with dementia and caregiver characteristics from both the healthcare third party payer perspective and the societal perspective. METHODS Several characteristics based on the cross-sectional data of 355 dyads of informal caregivers and persons with dementia living in Belgium were identified to include in a log-gamma generalized linear model and were used in a multiple linear regression model with bootstrapping to test robustness. RESULTS The mean monthly cost of care for a community-dwelling person with dementia was estimated at € 2339 (95% CI € 2133 - € 2545) per person from a societal perspective and at € 968 (95% CI € 825 - € 1111) per person from a third party payer viewpoint. Informal care accounted for the majority of the monthly costs from the societal perspective. Community based healthcare resource use represented the largest cost from the third party perspective. According to the regression analyses, a higher level of functional dependency of the person with dementia and a higher educational level of the caregiver were associated with a higher monthly cost from both a third party payer perspective and a societal perspective. In addition, being retired and a higher quality of life in the caregivers were associated with a lower monthly cost of care from the societal perspective. CONCLUSIONS Several characteristics of the caregiver and the person with dementia were associated with the monthly costs of care from a third party payer and a societal perspective. Despite the lack of clear causal relationships, the results of this study can assist policy makers in planning and financing future dementia care.

从第三方付款人和社会角度看，与痴呆症社区居民的护理费用相关的因素：横断面研究。

背景技术除了估计对痴呆症患者的护理对全球经济影响的重要性之外，还需要确定与该费用相关的关键因素。这项研究的目的是从医疗保健第三方付款人的角度和社会角度分析痴呆症社区居民的护理费用与护理人员特征之间的关联。方法根据比利时355个非正规照护者和痴呆症患者的dyad横断面数据，确定其几个特征，这些特征包括在对数伽玛广义线性模型中，并用于带有自举法的多重线性回归模型中，以检验稳健性。结果从社会角度看，痴呆症社区居民的平均每月护理费用估计为每人2339欧元（95％CI 2133-2545欧元），968欧元（95％CI 825-1111欧元）。从第三方付款人的角度来看每人。从社会角度看，非正式护理占每月费用的大部分。从第三方角度来看，基于社区的医疗保健资源使用是最大的成本。根据回归分析，从第三方付款人的角度和社会角度来看，痴呆症患者较高的功能依赖性和较高的护理人员教育水平均与较高的月度费用相关。此外，从社会的角度来看，退休后照料者的生活质量更高与每月照护成本降低有关。结论从第三方付款人和社会角度看，护理人员和痴呆症患者的一些特征与每月护理费用有关。尽管缺乏明确的因果关系，但这项研究的结果可以帮助决策者规划和资助未来的痴呆症护理。试验注册Clinicaltrials.gov NCT02630446，2015年12月15日。这项研究的结果可以帮助决策者规划和资助未来的痴呆症治疗。试验注册Clinicaltrials.gov NCT02630446，2015年12月15日。这项研究的结果可以帮助决策者规划和资助未来的痴呆症治疗。试验注册Clinicaltrials.gov NCT02630446，2015年12月15日。
