We have a feature called “Patient Listing Queues”. The UI for data integrity is just a patient listing page which is driven through a SQL query. The feature can be found here. The SQL query that is used to populate this page is available as a liquibase migration here. I don’t think there is a straight forward way to port it into ref app. This UI is not built specifically for Data Integrity. Its used as a tool for implementers to configure the views by themselves driven through a sql query.
