Worldwide growth in the number of people living with dementia will continue over the coming decades and is already putting pressure on health and care systems, both formal and informal, and on costs, both public and private. One response could be to make greater use of digital and other technologies to try to improve outcomes and contain costs. We were commissioned to examine the economic case for accelerated
investment in technology that could, over time, deliver savings on the overall cost ofcare for people with dementia. Our short study included a rapid review of international evidence on effectiveness and cost-effectiveness of technology, consideration of the conditions for its successful adoption, and liaison with people from industry, government, academic, third sector and other sectors, and people with dementia and carers. We used modelling analyses to examine the economic case, using the UK as context. We then discussed the roles that state investment or action could play, perhaps to accelerate use of technology so as to deliver both wellbeing and economic benefits.
