In Chile, there are currently over 200,000 persons living with dementia (PLWD) and, by 2050, this number is forecasted to exceed half a million. The associated national cost of dementia is $183 Million per annum and, by 2050, this will reach $457 Million. Given the implications of dementia, the Chilean Ministry of Health launched ‘Plan Nacional de Demencia: 2017-2025’ (cost: $12.5 Million) and, to support implementation, this project will enhance dementia-specific Health Economics capacity for Chile (and for the wider BrainLat region). This BrainLat Seed Research Grant aims to estimate stage-specific Quality-Adjusted LifeYears (QALYs), and relevant costs, to allow adaptation of international economic models to inform resource allocation decisions in Chile. By providing proof-of-concept, this initiative also lays foundations to scale up dementia-specific health economic capacity to benefit the wider RedLat region.
