Vault uses the following logic to populate this field:

Initial Case: Vault maps the date from one of the following Case fields, ordered by priority:

  1. New Info Date
  2. Initial Receipt Date

A Case is considered initial when it meets any of the following conditions:

  • For a report generated from a Transmission, the Transmission Reason field value must map to E2B Code I (Initial)
  • For a report preview generated from a Case, the Case Version must be less than or equal to 1.0

Follow-Up: Vault maps the date from the New Info Date field on the Case, if populated. A Case is considered follow-up when it meets any of the following conditions:

  • For a report generated from a Transmission, the Transmission Reason field value must not map to E2B Code I.

  • A Compounding Type
  • An FDA registration for a Product with a Compounding Type
5. If IND/PreANDA, Give Protocol # The Sponsor Study Number on the Case.
6. Type of Report Vault selects the appropriate checkbox based on the value in the FDA Report Type field, which is set based on the Due in Days reporting rule parameter. Otherwise, Vault selects checkboxes based on the following logic:
  • 5-day: When the Device Report Type field on the Case contains Public Health Risk.
  • 7-day: When the Case is tagged as a SUSAR and the Seriousness field on the primary Case Adverse Event contains Results in Death or Life-Threatening.
  • 15-day: Vault selects this checkbox using the following logic:
    • For an initial study Case, the Case is tagged as a SUSAR and does not qualify for the 7-day option (for example, the Seriousness field on the primary Case Adverse Event does not contain Results in Death or Life-Threatening).
    • For a postmarket spontaneous Case, whether initial or follow-up, the Seriousness field on the primary Case Adverse Event is populated and the Case Expectedness is set to No.
  • 30-day: For device malfunction-only reports.
  • Periodic: When any of the following conditions are met:
    • The Seriousness field on the primary Case Adverse Event is not populated.
    • The Seriousness field on the primary Case Adverse Event is populated and the Case Expectedness field is set to Yes .
    • The Case is a follow-up study Case tagged as a SUSAR.
  • Initial and Follow-up #: Vault selects these checkboxes using the following logic:
    • If a Transmission record exists for the Case and a value is populated in the Transmission Reason field:
      • If the Transmission Reason is Initial, Vault selects Initial.
      • If the Transmission Reason is populated with any other value, Vault selects Follow-Up #.
    • If there is no Transmission record associated with the Case:
      • If the Case New Info Date is on or before the Receipt Date, Vault selects Initial.
      • If the Case New Info Date is later than the Receipt Date, Vault selects Follow-Up #.

When no report type applies based on the above criteria, Vault selects the Periodic checkbox.

Vault populates the Follow-up # value from the Follow-up Number field on the Submission record.
7. Adverse Event Term(s) The Event (MedDRA) or the Event (Reported) - English on the primary Case Adverse Event.
8. Manufacturer Report Number

For device Cases, Vault exports the FDA Manufacturer Report Number on the Case Product on the Transmission. If blank, and only one Case Product on the Case related to the Transmission includes an FDA Manufacturer Report Number, Vault exports that value.

For non-device Cases and device Cases on which the FDA Manufacturer Report Number is blank, Vault maps the UID on the Case.
