GLOSSARY: Clinical Data Management (CDM)

Clinical Data Management (CDM), or Clinical Data Management System (CDMS), is used in clinical research to manage the data of a clinical trial. The clinical trial data gathered at the investigator site in the case report form are stored in the CDMS. To reduce the possibility of errors due to human entry, the systems employ different means to verify the entry. The most popular method is double data entry. Once the data has been screened for typographical errors, the data can be validated to check for logical errors. Another function that the CDMS can perform is the coding of data. Currently, the coding is generally centered on two areas; adverse event terms and medication names.
