Abstract
In this summary, we reviewed Japanese large databases available as pharmacoepidemiology data sources. In addition to the National Claims Database, two commercially available insurance claims databases are widely used: Japan Medical Data Center(JMCD) and JammNet.Three large pharmacy claims databases are also reviewed.The pharmacy claims database has unique characteristics in Japan because a prescription is valid only for four days and therefore the prescription records are believed to be almost identical to the dispensing records. Two large hospital-based databases are also available.In order to properly use these databases for the pharmacoepidemiological research questions, we need to learn first the medical practice and medical systems in Japan to have a better understanding for data source and data items. Automated large databases can be a powerful tool for pharmacoepidemiology studies by learning strengths and limitations of each database. (Jpn J Pharmacoepidemiol 2012; 17(2): 135-144)
