    • Strength Description -- A natural language description of the medication strength. For medications with multiple active ingredients, the standard convention is to list strength values in the alphabetical order of the active ingredients. (See also [URSA-CORE] Medication Strength)
    • Strength Numeric -- The numeric component of medication strength, expressed as a number, including non-integer values, if applicable. For medications with multiple strengths, this field should take the value of the first ingredient's numeric strength. (See also [URSA-CORE] Medication Strength)
    • Strength Unit Description -- The natural language description of the unit component of medication strength; e.g., mg, mg / 5 ml. (See also [URSA-CORE] Medication Strength)
    • Active Ingredients Description -- A natural language description of the medication's biologically active ingredient(s). For medications with multiple active ingredients, the active ingredients should be listed in alphabetical order.
    • Primary Agent Description -- The primary active ingredient in the medication. In medications with multiple active ingredients, this identifies by name only the primary agent.
    • AHFS Therapeutic Class Code 6-Digit -- The standard 6-digit AHFS Pharmacologic-Therapeutic Class Code, representing the first 3 tiers of the AHFS Pharmacologic-Therapeutic Classification system. The code is expressed as 6 numbers, without special characters delimiting the tiers, with leading and trailing zeros as needed.

The GFC is not manufacturer or package size specific, and can therefore be used in preparation of drug utilization reports and analysis of generic alternatives for substitution and formulary development. The GFC may also be used within pharmacy and claims administration systems as an efficient means of linking NDC numbers to clinical screening functions. (See also [URSA-CORE] Red Book Generic Cross Reference Code)

  • Metadata Fields

    • Other EMR Comments -- Any other annotations or comments associated with the current record entered into the EMR.
    • Record Last Updated Datetime -- The date and time the current record was last updated in the original data source.
    • Source Data Effective Datetime -- The "as of" date and time of the original source data system at the moment the current record was extracted. For example, if a snapshot of the data in a production system is taken at 12:05 AM on the first of each month and used to generate a package of flat files that are eventually loaded into the Ursa Studio client database later that month, the Source Data Effective Datetime of all records in that month's package will be 12:05 AM on the first. Not to be confused with Record Last Updated Datetime. (See also [URSA-CORE] Record Last Updated Datetime)
