I'm wondering how other sites are representing dates from NAACCR in i2b2. At UMN all our observation_fact records from NAACCR are loaded with a start_date of the date_of_diagnosis. We are also loading facts that have concept_cd values like "NAACCR:390|YYYYMMDD" for all 3 date fields.
I appreciate any input that can be provided. Thanks, -- Tim Meyer Programmer / Analyst Academic Health Center - Information Systems Phone: 612.624.8386 tme...@umn.edu
