Hi P?ria, archetypes model what clinicians would want to record about one discrete clinical idea/concepts. This is done in a maximum dataset fashion (meaning a single clincician would not need certain parts of the archetype) and forms the basis for semantic interoperability. Such archetypes are reused in many different use-cases. So the 'tobacco use' archetype does NOT aim at a certain disease. It should be used e.g. in a template of a lung cancer clinic and in a GP check-up template. This is why the maximum dataset is so important -> the archetype should include what the specialist and what the GP want to record. In the use-case specific template unnecessary archetype parts can be "stripped out".
What we did in the MIE session was to start the process of creating an archetype to record a patients tobacco use. Clinicians decide what goes in it (i.e. what they would normally as and note in narrative). Thus it contains statements about relevant past events like 'age commenced' and current facts e.g. 'average daily consumption' or the 'readiness to change the habit' (actually 'change' is another discrete concept and therefore modelled as a reference to another archetype). Here is the current 'tobacco use' archteype (is a specialisation of the more general 'substance use' archetype): http://svn.openehr.org/knowledge/archetypes/dev/html/en/openEHR-EHR-OBSERVATION.substance_use-tobacco.v1draft.html Your approach mentioned below seems reasonable. Step 1 would be the brainstorming (we often do this using mind-mapping software). As you correctly mentioned it is important to use existing archetypes if possible. This modularity and reusability is a strength of openEHR is what we think the main key for semantic interoperability (reusability on a large scale is only possible through the maximum dataset approach!). Hope this helped.
