ENCOUNTER_MAPPING Table
The ENCOUNTER_MAPPING table maps the i2b2 ENCOUNTER_NUM to an encrypted number, ENCOUNTER_IDE, from the source system (the 'e' in "ide" is for encrypted).
The ENCOUNTER_IDE_SOURCE contains the name of the source system.
The ENCOUNTER_IDE_STATUS gives the status of the patient number in the source system. For example, if it is Active, Inactive, Deleted, or Merged.

The information on this schema is incorrect as of v1.7.12a.
