Hi all,
I’m currently working on mapping transfusion and blood donation events into the OMOP CDM, and I’ve run into a few challenges I’d love to get some advice on.
Specifically:
- Mapping Donations and Transfusions:
- For blood donations, it doesn’t seem to be a rich set of standard procedure or observation codes in SNOMED or other vocabularies that clearly capture the act of donation (e.g., blood, plasma, platelets). I use generically the SNOMED code 4097300.
- Transfusions are mapped in the device exposure table.
- Linking Donations to Devices:
- I’m wondering how to approach this — especially using the
device_exposure
table in OMOP, and how/if links between person-level procedures (like donation or transfusion) and devices can be established meaningfully.
Given the limited standard codes in this domain, I’m curious:
- If anyone have worked on modelling blood donations and transfusions?
- Any advice on using custom concepts in this particular case?
- Any best practices for representing the relationship between donation events and devices?
Any advice would be very much appreciated!
