About Auto-Calculated Age Fields
This article clarifies how Vault Safety calculates the following Age fields:
- Age (normalized) (
age_normalized_year__v) - Age at Onset (
age_value__v) - Age Group (
age_group__v)
Age (Normalized)
Vault Safety automatically calculates the Age (normalized) field in the Case Patient section when the required data points are available:
- The Case Date of Birth
- The Case Adverse Event Event Onset. If an Event Onset is not available, the system uses the Case Receipt Date.
Note If there are multiple Case Adverse Events, the system uses the earliest event to calculate the age. For fetal adverse events, the system uses the event closest to the birth date.
If an Age at Onset value and unit already exists on the Case (for example, from E2B import), the system uses this value to populate the Age (normalized), converted to years.
Note The Age (normalized) field does not appear by default and an administrator must add it to the Case page layout.
Age at Onset
Once the system automatically calculates Age (normalized), it populates the equivalent value to Age at Onset.
Age Group
The system determines and automatically populates the patient’s Age Group depending on the Age at Onset:
| Age Group | Age at Onset |
|---|---|
| Fetus | 0 weeks/days/hours/minutes old |
| Neonate | More than 0 to less than 4 weeks old |
| Infant | 4 weeks to less than 12 months old |
| Child | 1 year to less than 12 years old |
| Adolescent | 12 years to less than 18 years old |
| Adult | 18 years to less than 65 years old |
| Elderly | 65 years and older |
How to Trigger Auto-Calculation of Age Fields
When you add or update the relevant fields on the Case or the Case Adverse Event, the system recalculates the Age (normalized).
Once Age at Onset is populated, the system calculates the Age Group based on this field.
Age (Normalized), Age at Onset, and Age Group Diagrams
The following diagrams show how the system auto-calculates the Age (normalized), Age at Onset, and the Age Group fields using the date intervals between the patient’s Date of Birth and the Adverse Event Event Onset.
Scenario 1: Age (Normalized) Populates Age at Onset
The Case contains a Date of Birth and Event Onset value but no Age at Onset.
The system automatically calculates Age (normalized) and uses this value to populate Age at Onset. The system then uses the Age at Onset value to calculate Age Group.
Scenario 2: Age at Onset Populates Age (Normalized)
- The Case contains an Age at Onset value (from E2B import) and no Date of Birth or Event Onset value.
- The system automatically uses the Age at Onset field value to populate Age Group and Age (normalized), converting it into “years” if not already.
Scenario 3: Override Age at Onset
- The Case contains a Date of Birth and Event Onset value but no Age at Onset.
- The system automatically calculates Age (normalized) and uses this value to populate Age at Onset. The system then uses the Age at Onset value to calculate Age Group.
You can override the Age at Onset by manually entering a value in this field. After saving the Case, the system retains this Age at Onset value and uses it to re-populate Age (normalized) and Age Group.
Scenario 4: Override Age (Normalized)
- The Case contains an Age at Onset value (from E2B import) as well as a Date of Birth and Event Onset value.
- The system automatically uses the Age at Onset field value to populate Age Group and Age (normalized), converting it into “years” if not already.
- You can override the Event Onset by manually entering a value in this field.
After saving the Case, the system re-calculates the Age (normalized) field and re-populates the Age at Onset with this value. The system then uses the Age at Onset value to calculate Age Group.
Note that overriding the Date of Birth value in step 3 also results in the system re-calculating Age (normalized).
