ABSTRACT

Studies using real-world data are recently increasing worldwide. Various types of real-world data are available in Japan. Administrative claims databases include the National Database (NDB) and other types of databases including several commercially available databases. This article describes the DeSC database, newly constructed by DeSC Healthcare Co., Ltd. in 2020. One of the features of the DeSC database is that it includes data from the National Health Insurance, Health Insurance, and Advanced Elderly Medical Service System. In the present article, we referred to our previous study on population representativeness of the DeSC database and explained its overview. Estimated prevalence of some diseases were described for each type of insurance. Furthermore, we discussed the use of the DeSC database for clinical epidemiology and pharmacoepidemiology research.
