Time value of informal care of people with alzheimer’s disease in Spain: a population-based analysis

Abstract

AbstractThe aims of this paper are to estimate the monetary value of informal care for people with Alzheimer’s disease (AD) in Spain, to compare results with those obtained in 2008 and to analyse the main determinants of the time of the value of informal care. The Survey on Disabilities, Autonomy and Dependency carried out in Spain in 2020/21 was used to obtain information about disabled individuals with AD and their informal caregivers. Assessment of informal care time was carried out using two alternative approaches: the replacement method, and the contingent valuation method (willingness to pay & willingness to accept). The number of people with AD residing in Spanish households and receiving informal care rose to more than 200,000, representing an increase of 43% compared with 2008. The average number of hours of informal care per week ranged from 86 to 101 h, with an estimated value of between €31,584 - €37,019 per year per caregiver (willingness to accept) or €71,653 - €83,984 per year (replacement). The annual total number of caregiving hours ranged between 896 and 1,061 million hours, representing between 0.52 and 0.62 of GDP in 2021 (willingness to accept) or 1.19–1.40 of GDP (replacement). The level of care needs plays a central role in explaining heterogeneity in estimates. These results should be taken into account by decision-makers for long-term care planning in the coming years.
