  • Data Model Keys

    • Medication List Entry ID -- The internal database identifier (used, e.g., for joins and primary keys) for the medication list entry. (See also [URSA-CORE] Medication List Entry)
    • Patient ID -- The internal database identifier (used, e.g., for joins and primary keys) for the patient. This value is typically mastered, i.e., all records for the same patient, regardless of the source data system from which that record originated, should have the same Patient ID value. (Note that while the mastered Patient ID value might resemble a local identifier used in one of the upstream data sources, this does not indicate any special priority of that source system in determining the characteristics of the patient.) (See also [URSA-CORE] Patient)
    • Medication ID -- The internal database identifier (used, e.g., for joins and primary keys) for the medication. (See also [URSA-CORE] Medication)
