Re: Archetype use for generic patterns and/or for real patient data

HI Jon

I think we have 4 levels in openEHR at the moment and you are proposing a 5th…

The openEHR Reference Model is how to represent data in the health record - all data conform to this

The openEHR Archetype Model is how to describe what data can be recorded in a health record - all archetypes conform to this

openEHR archetypes define what content can be recorded in health record

openEHR templates aggregate and refine archetypes to describe useful sets of data to record in the health record - these are for a particular purpose.

I think you are describing templates which are partially populated and have choices. This is even closer to the application space. The template constraints do allow for this sort of pre-population and it could be experimented with if you see these as valuable.

Cheers, Sam

There are numerous situations in EHR-systems, where a general pattern of what to do exists, and then is used for a patient in a given situation, resulting in EHR-records based on this pattern. It is unclear to me to what extent the archetypes may be used for modelling such patterns, and how to move from such general patterns to the archetypes containing the real patient related data.


The following example is meant to illustrate the issue:


Several patients may have the same medical condition and should (according to clinical guidelines) have care plans that are very similar. The care plan for each patient may be documented using the Care Plan Archetype. These care plans all come from a common “care plan” described for the medical condition in question. If this generic care plan also was described in the form of archetypes, f.i. using the Care Plan archetype also for generic patterns, some advantages may appear.  


My impression is that use of archetypes for such patterns is not described, investigated or advocated in the community. I may be wrong (being a newcomer) or there may be good reasons for this, of which I would be happy to be informed about. On the other hand, if this is a question waiting to be addressed, I would like to see the debate around this evolve. 


Best regards
