About Latency
Vault Safety automatically calculates the First Dose Latency and Last Dose Latency fields on the Case Assessment when the required data points are available.
The following list summarizes the dates that the system uses to calculate the latency period:
- The Onset field on the Case Adverse Event
- The First Admin Date field on the Case Product Dosage
- The Last Admin Date field on the Case Product Dosage
Note The above fields must specify a minimum precision to the day in order for auto-calculation to occur.
How to Trigger Latency Auto-Calculation
When you add or update fields on the relevant Case Product Dosage or Case Adverse Event, the system recalculates the latency fields.
Dose Latency Diagrams
The following diagrams show how the system auto-calculates the First Dose Latency and the Last Dose Latency fields using the date intervals between the Onset date and the First and Last Admin Date, respectively.
Diagram A: First Dose Latency Calculation with Date Precisions to the Day
The First Admin Date and Onset date are populated with a precision to the day (YYYY/MM/DD).
Upon saving the Case Product Dosage and Case Adverse Event records, the system automatically calculates the First Dose Latency with a precision to the day.
Diagram B: Last Dose Latency Calculation with Date Precisions to the Day
- The Last Admin Date and Onset date are populated with a precision to the day (YYYY/MM/DD).
- Upon saving the Case Product Dosage and Case Adverse Event records, the system automatically calculates the Last Dose Latency with a precision to the day.
Diagram C: Latency Calculation with Precisions to the Time of Day
- The First Admin Date, Last Admin Date, and Onset date are populated with a precision to the time of day (YYYY/MM/DD HH:MM).
- Upon saving the Case Product Dosage and Case Adverse Event records, the system automatically calculates the First Dose Latency and Last Dose Latency with even more precision.
Note For the system to calculate the Latency fields with this precision, both the Onset date and the Admin Date must be specified with a precision to the time of day.
