Chang Gung Research Database (CGRD)

The Chang Gung Research Database (CGRD), the largest multi‐institutional electronic medical records (EMR) collection in Taiwan, provides access to researchers with standardized patient‐level data. It is the first and largest EMR database encompassing multiple medical institutions, covering 6.1% of outpatients and 10.2% of hospitalized patients in Taiwan. The CGRD contains more detailed clinical information that is not available from claims databases, such as Taiwan's National Health Insurance Research Database (NHIRD). In addition to prescriptions, diagnoses, and procedure records, the CGRD includes information from pathological reports and laboratory results such as HbA1c, eGFR.
