Hi Pariya, I agree with Denis's description of the use of Item_tree archetypes, as embedded archetypes which act as the whole contents of a parent archetypeand can be reused in a different parent archetype, Medication being the best example.
We are finding that it is much more common to want to reuse only *parts* of an archetype and I think you might be better to think of using CLUSTER archetypes. I am currently working on some lab_test archetypes and have developed a CLUSTER.specimen archetype which is reused within archetype slots in a number of different lab-related archetypes, and in different slots within the same parent archetype: this reflects different relationships of specimen descriptions to the lab_test result - sometimes the specimen relates to the whole test and sometimes to a partial sun-result.
