Dear All
In developing an ontology for health record recordings - an archetype
ontology - I have come to the idea that there is a great deal of utility in
the idea of an 'action specification'. This is the part of an instruction
that says what to do - not when (or under what conditions) to do it.
Let me give you an example:
A medication order is an instruction:
medication=Amoxycillin: dose=250mg: route=IV: frequency=three
times daily
The action specification is:
medication=Amoxycillin: dose=250mg: route=IV
The when part is:
frequency=three times daily
OR A Pap test notification instruction might consist of:
Action is Pap Test & send specimen to laboratory
When is two years since last pap test OR 1/1/03
The important thing is that the 'action specification' can be reused in the
EHR as a record of what was done. So a medication administration reuses the
action specification of a medication order - and has a record of who
administered it - likewise for the Pap test.
There may be no need to do this at the information model level - perhaps
leave it to the application. But there are some advantages - a consistent
description of what is to be done and what was done using the same
structure - guaranteed transformation from an instruction to recording an
action.
