  • The data are calculated from claims registered in the NDB. The data do not always reflect the precise antibiotic use because the data of patients who receive publicly funded health care are not always included. The numerical values are different from those of the surveillance of antibiotic sales (http://amrcrc.ncgm.go.jp/surveillance/020/20190902163931.html) due to the different data source.
  • The figures indicate drug utilization standardized by defined daily dose (DDD) per population and drug, called DID (DDDs/1,000
    inhabitants/day) (Reference:https://www.whocc.no/atc_ddd_index/). The DDD is according to data published on January 1, 2017.
  • The population is according to estimates published by the Statistics Bureau, Ministry of Internal Affairs and Communications, Japan. (https://www.stat.go.jp/data/jinsui/)
