Importing NHSD medication codelists from SNOMED refsets #233

Open chrisjwood16 opened 2 years ago

chrisjwood16 commented 2 years ago

Impact and Investment Fund business rules specify a number of medication codelists within SNOMED refsets.

The medication lists can be viewed by searching corresponding SNOMED code in SNOMED browser, (example) then selecting members tab. The list defaults to displaying only the first 100 items, an extra 100 items can be added at a time with further clicking but some items contain a few thousand items making this time consuming.

I'm not sure if there is already a way to import these into OpenCodelists? If not I'm wondering how much effort would be needed to setup a way to do this. I can do manually if complex/time consuming to implement. But there are likely to more of these requiring import in future:

My recollection is that there is another NHSD website that has .txt files that we imported

Ah great thanks Brian, Done some more digging - seems the following contains the info needed: https://isd.digital.nhs.uk/trud/users/authenticated/group/0/pack/26/subpack/105/releases

Full drug ref sets are contained in the file: der2_Refset_SimpleUKDGFull_GB1000001_20220706.txt

Relevant fields: refsetId contains SNOMED parent code as in table above. referencedComponentId contains SNOMED code for each drug within ref set. One row per component. active - needed to anything filter out anything marked as inactive

If there is a process in place to extra and import into OpenCodelist that would be great. Otherwise I can work with these files.
