Data Flow (High Level)

The flow is centered around the use of the FHIR "ServiceRequest" resource to initiate follow-ups in the community.

1. Requesting system determines which patients need follow-up
2. Requesting system creates a ServiceRequest for each patient and sends the ServiceRequest to HIE
3. CHIS queries the HIE to determine if there are any patients to follow-up with
4. Requesting system returns results of CHIS' query
5. CHIS determines where or not to claim the service request
6. CHIS "claims" the ServiceRequest to confirm that they will be following up with the patient
7. CHIS tasks the appropriate CHW with finding and advising the patient
8. CHIS records the results of the CHW's efforts
9. CHIS updates the ServiceRequest
10. Requesting system receives update
11. Requesting system updates itself accordingly
