Any reverse lookups that are configured to be shown as part of the Epic Integration will be displayed as part of the Scan to Multiple flows within Front Office Scanning (FOS) and Scan Acquisition Server (SAS). The Scan to Multiple flow allows users to use a reverse lookup to indicate which record documents should be indexed to. Both FOS and SAS will indicate which record is being indexed to after a selection is made.
For performance reasons, queries against all reverse lookups are executed at application startup. This allows instant load times when a user selects the reverse lookup that they would like to use to pick a record to scan to.
Reverse lookup is always executed based on the patient identifier, and on any other static filters that are configured. You do not manually enter filter criteria as you would with traditional reverse lookups.
Refer to the Integration for Epic documentation for information on executing reverse lookups when indexing in SAS or FOS.
