Meeting Notes July 30, 2019

Topics

• Rimma Belenkaya reviewed the latest draft of the ETL documentation including coverage for NAACCR numeric concepts.
  • The group discussed how to handle NAACCR items codes that represent numeric ranges. There is no current mechanism or convention within OMOP covering this use case. See forum discussion here:

    • The group agreed to test out Rimma's recommendation for representing numeric ranges as two entries within the MEASUREMENT table. Michael raised the issue that this will require manual curation by the OMOP vocabulary team that might not be scalable in the future – to make the necessary entries within the new CONCEPT_NUMERIC table. Michael also raised data quality concerns about creating duplicate non-connected entries within the MEASUREMENT table. The group agreed to reassess Rimma's recommendation after ETL testing.
