Updating Metrics
Several jobs in Vault update Subject Metrics. These metrics are critical for managing studies and are leveraged across the system, including on the Study Manager and CRA home pages, within features that link Monitoring and Complex Trials, and in the separate Payments application. The jobs function as follows:
| Job | Dependencies | Scheduled Start Time | Description | Supported Metrics Calculation |
|---|---|---|---|---|
| Update Metrics | Runs when you add a new Subject, remove a Subject, or update a subject’s Study, Study Country, Study Site, Subject Status, Subject Group or, if calculating Date-Based metrics, Subject Status dates, such as Enrolled Date. Does not run for archived studies. | Starts one hour after the first change to a subject | The job runs independently for each Study and only updates Metrics and, if applicable, Metrics Over Time records for areas that you added or changed. For example, if you add an Enrolled Date to a subject, only the Total Enrolled metric/metric over time is updated. This job will also update or create Enrollment Status Logs. Does not update metrics for archived studies. Vault notifies you if the Update Metrics job fails. | * Status Snapshot * Date-Based |
| Update Monitored Metrics | Runs when you add a new Monitored Subject, remove a Monitored Subject, or update a Monitored Subject’s Subject Status or, if calculating Date-Based metrics, Subject Status dates, such as Enrolled Date. | Starts five minutes after the first change to a Monitored Subject. | Vault creates a set of monitored metrics the first time this job runs. Vault keeps monitored metrics in sync with changes you make to monitored subjects. | * Status Snapshot * Date-Based |
| Recalculate Enrollment Metrics | Runs when you execute the Recalculate Enrollment Metrics user action on a Study. | User determined | Recalculates all Actual Metric values (Actual Total Enrolled, Actual Completed, etc.) on all Metrics and, if applicable, Metrics Over Time-related object records at the Study, Study Country, Site, and Subject Group levels. If calculating Date-Based metrics, Vault will also recalculate Enrollment Status Logs. For studies using the Metrics Only , the job resets all Metrics values to zero. When you run the job for a Study with the Transferred Metrics setting, Vault displays an error. | * Status Snapshot * Date-Based * Metrics Only |
| Update Metrics (Metrics Only) | Runs when a study has a Metrics Calculation value of Metrics Only | Starts one hour after the first change to a metric | This job runs independently for each Study and updates metrics changes automatically from Study Sites to Study Countries and Study Countries to Study level. It also creates Enrollment Status Log records for days with changes. Vault notifies you if the Update Metrics (Metrics Only) job fails. | * Metrics Only |
