We are working on a registry project where many of the Registry data elements are “made up” (think, “Favorite ice cream flavor”). We are then pulling data from the EHR that helps answer the registry question (think, SNOMED 3241314 “Addiction to Chocolate”).
So my question is, how would you set this up? Current working idea:
Create local Observation concepts for the registry questions and write the results of each question to the Observation table with value as string (eg “Chocolate”)
Write a condition_occurrence for the EHR finding (eg occurrence of “Addicted to Chocolate” on date xyz)
Create a FACT_RELATIONSHIP connecting the two (eg has_evidence)
Does this sound like the right way to go?
