JMDC Claims Database

The JMDC Claims Database is an epidemiological receipt database that has accumulated receipts (inpatient, outpatient, dispensing) and medical examination data received from multiple health insurance associations since 2005. The cumulative dataset is approximately 7.3 million subjects (as of April 2020), and it is possible to follow the prevalence rate and incidence under a general population, including healthy individuals. Even if a subject transfers hospitals or uses multiple facilities, the data can be tracked. The database is used by major pharmaceutical and medical device manufacturers, life insurance companies, non-life insurance companies, government offices, and more than 50 universities in Japan.

Database that allows complete count surveys

The data source is all members of multiple contracted health insurance associations, and complete count surveys are possible, including healthy people who have not received a receipt.



Real World Data

The JMDC data is from the actual medical treatment (real world) that combines the receipt, medical examination data, and ledger information. All claims received at the insurance medical institution are collected by the insurer, so even if a single patient visits multiple medical institutions, all the details of the medical treatment can be captured. In addition, the database holds all attribute information (excluding personal information) including for subjects who have not received a receipt from the ledger information.

Health Insurance Claims Data
JMDC obtains all health insurance claims data (inpatient, DPC, outpatient, dispensing) of the observation group.
Medical Examination Data
We also collect the results of medical examinations conducted by the health insurance associations.
Ledger information
We also obtain ledger information that health insurance associations use to manage subscribers.

Time series analysis on patient axis is possible

All receipt information is converted into data and can be tracked on a patient basis, so that the flow of consultation and treatment can be comprehensively understood.
