Requirements

This is required so the CRO knows which patients have consented to their PKB clinical trial teams. This query is per PKB clinical trial team, and each trial team has its own HL7 team-level credentials.

You'll use an HL7 A19 Query with a timestamp filter to retrieve patient records. You should dynamically update the timestamp to match the last time you checked. This ensures that each query only returns patients added since the last request, preventing duplicate data and ensuring completeness.
