The AMA licenses its Physician Masterfile to Database Licensees who make the database available to others. More information about licensing can be foud here. The process for acquiring data may vary by licensee. The remainder of this entry describes the process for accessing and using data provided through the licensee Medical Marketing Service, Inc. (MMS). Researchers can contact Tom Lorge ([email protected]) directly to request access to the data through MMS. As part of the application process, researchers must complete a data use agreement (DUA). MMS does not require IRB approval for data access.
Generally, only de-identified data are made available to researchers (i.e., data are provided without name and address). Identifiable data may be requested by detailing how the data will be used and why identifiable data are needed.
Lag time varies depending on the data licensee. Medical Marketing Service, Inc. advertises daily updates of their database.
