Dear colleagues,

*Apologies for cross posting – just wanted to ensure that we share these insights broadly…*

We recently passed the eleven-year anniversary for the first upload to the international CKM – the body temperature archetype. As Europe readies itself for summer holidays and the clinical review season slows down, it is a good time to review the progress of the openEHR clinical modelling program.

Roughly 6 weeks ago I created and downloaded a number of reports from CKM. I’ve spent some time analysing the data and thought I’d share what I learned with you.

This exploration was triggered by a tweet from Ewan Davis last December asking:

*“How many person hours do you think has gone in to creating the openEHR archetypes available via CKM - I think it must be in excess of 100,000 hours (40 person years)”*

It took a while to gather the data and propose reasonable assumptions so that we could make time and effort estimates, but here goes…
