Tom and others The idea of age as a complex notion - post-conception, gestational (LMP) ie it can involve pre-birth periods - even well into life. This apperas to be important for decision support.
I wonder if we need to model this as an archetype for demographics - but it needs to be in the EHR - age crops up in lots of evaluations (problem, family history) so we might need to have it as a formal TYPE! That is - we can use it consistently in various settings. I would argue that gender is of the same nature - with social gender, physical gender and genetic gender as the key concepts. No doubt there are others but these two are worth thinking about carefully. Sam - If you have any questions about using this list, please send a message to d.lloyd at openehr.org
