How Age Fields are Calculated

Vault Safety automatically calculates and populates the Age (normalized), Age at Onset, and Age Group fields

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)

By default, the system uses the Date of Birth (dob_idate__v) on the Case to calculate the following:

• Age (age_value_v) and Age Unit (age_unit_v)
• Age (normalized)
• Age Group

If the Date of Birth is not provided, the Age and Age Unit fields can be populated on the Inbox Item or Case through data entry or import. When provided, the system calculates Age (normalized) and Age Group based on these values. If an initial Case includes Age and Age Unit values, when a Follow-up Case is created those values are populated from the initial Case.

If the Date of Birth, Age, and Age Unit fields are blank on the Inbox Item, the system cannot auto-calculate.

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.

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.

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	1 month to less than 24 months old
Child	2 years 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

1. The Case contains a Date of Birth and Event Onset value but no Age at Onset.
2. 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)

1. The Case contains an Age at Onset value (from E2B import) and no Date of Birth or Event Onset value.
2. 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

1. The Case contains a Date of Birth and Event Onset value but no Age at Onset.
2. 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.
3. 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)

1. The Case contains an Age at Onset value (from E2B import) as well as a Date of Birth and Event Onset value.
2. The system automatically uses the Age at Onset field value to populate Age Group and Age (normalized), converting it into “years” if not already.
3. You can override the Event Onset by manually entering a value in this field.
4. 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. Overriding the Date of Birth value in step 3 also results in the system re-calculating Age (normalized).
