Patient Enrollment

Clinical Alerts uses enrollment to determine which patients are eligible for alert generation. Your organization selects the enrollment model that fits its alerting strategy.

Enrollment Models

Clinical Alerts supports two enrollment models. Both models use a FHIR Group resource to represent eligible patients, but they differ in how group membership is established and maintained.

Limited Enrollment

Your organization controls which patients trigger alerts by adding them to a FHIR R4 Group resource that represents the enrolled population. Alerts are generated only for patients in that group. Use Limited Enrollment when you need explicit control over which patients are monitored.

All-Tenant Enrollment

All patients associated with your tenant are automatically enrolled through a FHIR R4 Group resource with an all-patients characteristic. New patients are included as they are added to the tenant. Use All-Tenant Enrollment when alerts should apply to your entire patient population without explicit membership management.

Enrollment Principles

Enrollment operates prospectively. Alerts are generated only for patients who are actively enrolled at the time qualifying document-driven activity is processed.

Enrollment alone does not generate alerts or initiate document retrieval. Qualifying document-driven activity must occur during an active observation window for an alert to be produced.

Timing Considerations

Clinical Alerts processes activity asynchronously. Enrollment changes may take several minutes to propagate, and a patient must be enrolled at the moment qualifying activity is processed. Retroactive alert generation does not occur, even if the patient is enrolled shortly after the activity is detected.

Responsibilities

Your organization is responsible for:

  • Selecting the enrollment model that fits your alerting strategy.
  • Maintaining Group membership with Limited Enrollment.
  • Ensuring enrollment reflects the patient population you want to monitor.
