Value assessment of new interventions for Alzheimer's disease dementia in Japan based on literature review and group interview.

There are several limitations to how QOL is measured, particularly for patients with ADD. Public long-term care costs represent a substantial proportion of total costs and should be included in the assessment and decision-making of ADD, even from the payer's perspective. Following that, a process is required to take informal care costs into account in decision-making, regardless of whether they are included or not in a base-case analysis. The importance of other elements of care burden that cannot be quantitatively measured should also be recognized and reflected in decision-making.
