Objective To analyze the chronological change in social burden of dementia in Japan for policy implications of appropriate resource allocation and quality improvement.Design National, population-based, observational study from 2002 to 2014.Setting Seven nationwide data sets from Japanese official statistics.Method Comprehensive Cost of Illness method.Main outcome measures The outcome variables included healthcare services, nursing care services, informal care (unpaid care offered by family and relatives), mortality cost and morbidity cost.Results The number of patients with dementia increased 2.50 times from 0.42 million in 2002 to 1.05 million in 2014. While the number of patients living in homes and communities increased by 3.22 times that of patients living in nursing care facilities increased by 1.42 times. The total social burden increased 2.06-2.27 times from JPY 1.84-2.42 to 3.79-5.51 trillion (JPY 1 trillion = US$ 100 billion). Regarding the total burden, the proportion of informal care provided increased from 36.6-51.9% to 37.7-57.2%. Furthermore, the proportion of primary caretakers aged >= 70 years increased from 27.6% to 37.6%.Conclusions Owing to the promotion of Deinstitutionalization' (shift of nursing care site from in-facilities to in-home and in-community), Elderly care by the elderly,' and Earlier diagnosis of dementia,' the average cost per patient reduced by 0.82-0.91 times from JPY 4.37-5.77 to 3.60-5.24 million. Therefore, the management of informal care in a manner that does not exceed the acceptable limit of the patients' caretakers, while maintaining patient safety and quality of care, is imperative.
