We should maybe revisit the current modelling patterns for medication amounts and their units. Currently, we have amounts expressed as a DV_QUANTIY with units constrained to ‘1’, and an additional DV_TEXT element for the unit. This undermines the DV_QUANTITY data type, and doesn’t work particularly …

Yes . It was due to Quantity originally not supporting non-UCUM units.

I’m glad you agree! I’ve created new revision branches for each of the archetypes: INSTRUCTION.medication_order CLUSTER.medication CLUSTER.dosage CLUSTER.medication_supply_amount There are additional change requests for some of these, but can we go forward with these changes, in addition to any …

I’ve a similar question relating to units. We’ve a need to describe a quantity of Grays (Gy) in centigrays cGy) and also to a lesser extent volts (V) in kilovolts (kV). We’re using dv_quantity, but there doesnt seem to be an option for these two, or a prefix option on dv_quantity. I think Uuom note…

Reposting to a new thread on tooling - Adding to the DV_QUANTITY units options

I’m going forward with these proposed changes, since there has been no negative feedback in the month that has passed since the above was posted. The INSTRUCTION.medication_order and CLUSTER.medication and CLUSTER.dosage all have open and unresolved change requests though. Could I ask those who have…

I scanned the CRs. Most seem uncontroversial. We currently only implement the medication cluster (for covid vaccin and wound treatment medications). But at first glance I don’t see any problems with this proposal or the CRs. Keeping the archetypes aligned with FHIR would be valuable to us, since our…

My preference is to keep ‘Route’ at the current level but also add it lower down the tree to be associated with specific dose instructions, which is the gap we have now, mostly for fairly obscure Mental health examples. The vast majority of mixed-route instructions are readily handled by the current…

[image] ian.mcnicoll: fairly obscure Mental health examples Do we have these examples available? Seeing them would help a lot with understanding how to model this well.

From Christine Wadsworth who isa Pharmacist and Better’s UK Clinical Lead. Olanzapine oral vs IM may have the same dose ranges and maximum daily dose but would have different instructions e.g. If olanzapine IM is given then must wait >1 hour before administering lorazepam Haloperidol oral vs IM –…

There is already very high alignment with FHIR in themed models, and I agree we need ot keep that close, where possible.

One issue that we might want to try to resolve
