A problem the community has been looking at in openEHR for some time is
how to deal clearly with order-related meta-data (typically: requestor
and receiver ids of various sorts). The topic of 'orderables' has been
mentioned in some recent discussions in CIMI
<http://wiki.hl7.org/index.php?title=Proposed_CIMI_Reference_Model>, and
as a result, some model changes proposed. One is the addition of an
'ENTRY_GROUP' class. A similar idea may be useful in openEHR. The
problems it could address include the following:
* provide a clear place to put order-related information
* better match for Panel/Analytes in Lab data
* provide a container structure that matches Order Sets
See this page
<https://openehr.atlassian.net/wiki/display/spec/RM+additions+for+workflow+process>with
some modelling ideas on this topic.
