The societal costs of dementia in Sweden 2012 - relevance and methodological challenges in valuing informal care

In this study, we sought to estimate the societal cost of illness in dementia in Sweden in 2012 using different costing approaches to highlight methodological issues. We conducted a prevalence-based cost-of-illness study with a societal perspective. The societal costs of dementia in Sweden in 2012 were SEK 62.9 billion (approximately €7.2 billion, approximately US$9.0 billion) or SEK 398,000 per person with dementia (approximately €45,000, approximately US$57,000). By far the most important cost item is the cost of institutional care: about 60% of the costs. In the sensitivity analysis, different quantification and costing approaches for informal care resulted in a great variation in the total societal cost, ranging from SEK 60 billion (€6.8 billion, US$8.6 billion) to SEK 124 billion (€14.1 billion, US$17.8 billion). The societal costs of dementia are very high. The cost per person with dementia has decreased somewhat, mainly because of de-institutionalisation. The majority of the costs occur in the social care sector, but the costing of informal care is crucial for the cost estimates.
