I am presently working on a project involving blood products and understand that a decision was made that blood products belong in device_exposure. We are using CDM6.0, as we started prior to the suspension of its development.
What is the protocol for revising a table under CDM6.0? I would like to use the device_exposure.unit_concept_id field added in 5.4.
I don’t know whether there are other groups using 6.0. Are they just abandoning attempts to keep to the standard and customizing ad hoc? We would like to stay as close to compliance with standards as we can.
