Preventing loss of autonomy has become a public health issue due to the increase in healthcare costs associated with ageing. It has become even more pressing with the arrival of the baby-boomer generation. This has given rise to several initiatives. This is the background to the VIVADOM project. The project provides a complete kit for older adults aged 60 years and over living at home. First, the kit includes a technological package (telecare, light path and digital tablet). Then, these older adults benefit from personalised human support provided by postal workers trained in gerontology. The aim of this study will be to carry out a health economic assessment (HEA) of the VIVADOM project as part of the prevention of frailty and/or dependency (by comparing beneficiaries of the complete kit with non-beneficiaries). The comparator will be the fact of not benefiting from the complete kit. In addition, the efficiency of the project in preventing falls and cognitive problems will be studied. We will calculate three incremental cost-effectiveness ratios (ICER) for these three issues.
The economic model used will be the Markov model. Transition probabilities, average costs and average quality-adjusted life year (QALY) will be calculated for the two groups being compared. The ICER will be obtained by dividing the difference in average costs by the difference in average QALYs. Finally, ICERs will be compared with willingness-to-pay (WTP) to assess the efficiency of the system. Thus, the VIVADOM project will be efficient when these ICERs are lower than the WTP. Univariate and probabilistic sensitivity analysis will be carried out to ensure the robustness of the analysis results.
The HEA of the VIVADOM project has been approved by the research unit of the University of Limoges in France. The results will be published in a peer-reviewed journal and presented at relevant national and international conferences.
由于与老龄化相关的医疗保健成本增加，预防自主性丧失已成为一个公共卫生问题。随着婴儿潮一代的到来，这一问题变得更加紧迫。这引发了多项举措。这就是VIVADOM项目的背景。该项目为60岁及以上居家老年人提供一套完整的工具包。首先，该工具包包括一个技术包（远程护理、光路和数字平板电脑）。然后，这些老年人受益于由接受老年医学培训的邮政工作人员提供的个性化人文支持。本研究的目的是对VIVADOM项目进行健康经济评估（HEA），作为预防衰弱和/或失能的一部分（通过将完整工具包的受益者与非受益者进行比较）。对照将是未受益于完整工具包这一事实。此外，将研究该项目在预防跌倒和认知问题方面的效率。我们将针对这三个问题计算三个增量成本效益比（ICER）。
所使用的经济模型将是马尔可夫模型。将为被比较的两组计算转移概率、平均成本和平均质量调整生命年（QALY）。ICER将通过平均成本差异除以平均QALY差异获得。最后，将ICER与支付意愿（WTP）进行比较，以评估该系统的效率。因此，当这些ICER低于WTP时，VIVADOM项目将是有效的。将进行单变量和概率敏感性分析，以确保分析结果的稳健性。
VIVADOM项目的HEA已获得法国利摩日大学研究单位的批准。研究结果将发表在同行评审期刊上，并在相关的国家和国际会议上展示。
