Published Fields

  • Data Model Keys

    • 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)
    • Source ID -- The identifier for the original source data system from which the current record originated.

  • Source Local Keys

    • Source Local Patient ID -- The internal database identifier for the patient in the source data system this record originated from. (See also [URSA-CORE] Patient)
    • Source Local Patient Master Identity ID -- An identifier used to uniquely identify the patient in the original source data system; typically derived through a data mastering process that identifies duplicate Source Local Patient ID values for the same (real-life) patient.

  • Operations Support Fields

    • Patient Operational ID -- The user-facing value used by staff used to uniquely identify the Patient in their administrative systems and/or day-to-day operations. (See also [URSA-CORE] Patient)
