Outline of Final Research Achievements

Recently a lot of expensive healthcare technologies are developed, however medical expenditure is limited because of rapid aging and low economic growth. Therefore, the role of economic evaluation becomes more important. In this research, I surveyed the influence of disease characteristics on the people’s (or doctors’) preference. In addition, I evaluated population norms of QOL score and explored the factors which is related to QOL scores.
