Master Patient Index (MPI) Policy Term Definition

This index identifies all patients who have ever been admitted to or treated by UTMB, or have been scheduled to receive treatment. It is the key to locating patient medical record information. It is not an index of legal identities but is an index of all identities used by patients.

The master index resides in Invision in an application called the PIDX (Patient Index); copies are maintained in MYUTMB and is named the Enterprise Patient Index (EPI), and in Epic.
