What is the suggested IHE strategy for the communication between a
report creator and the image display actor, if they are not grouped,
as suggested in the reporting workflow Integration Profile?

When the report creator retrieves the reporting worklist from the
report manager, it must inform the image display about the studies
that need to be retrieved from the archive. After completion of the
report, the image display should be informed so that it knows that
certain cases are no longer needed. Complication no.1: Work items can
vanish from the reporting worklist without ever being claimed by the
report creator which is "close" to the image display, e. g. because
multiple workplaces work off the same worklist, or in case of "no
shows".

I don't see if any of the IHE Integration Profiles addresses this
scenario?
