It was discussed that this task is only confined to treatment variables. But that other leading zero problems might exist as well for other NAACCR variables. Dymtry will manually fix the NAACCR treatment variables.
The 'NAACCR Proc Schema' entries do not have all the necessary relationships to ICDO codes via 'Proc Schema to ICDO'.
Dymytry said that the building of these Metadata concepts is part of the vocab release process. Since the DDL for the extension tables is not part of an official release, these concepts don't get created. For the time being, Dymytry will provide script in the OncologyWg repository that ETLers will need to run.
Move NAACCR Treatment 'did not happen' concepts into the Observation domain.
It was agreed that for the time being only Treatment NAACCR item codes describing flavors of 'did not happen' or 'unknown' will be moved into the Observation domain. Diagnosis and Treatment modifiers could possibly in the future also be placed in the Observation table. Jermey Warner raised the possibility of adding a 'Plan' domain to OMOP to represent these kinds expectational/intentional data.
Create new 'Regimen' domain, move all the Hemonc.org regimens into the new domain, create entries in the new domain for NAACCR high-level drug concepts and non-standardize existing drug NAACCR item codes.
It was agreed to move Hemong.org 'Regimen Type' classification concepts into the new 'Regimen' domain. It was recognized that Hemong.org 'Regimen Type' are exact matches for new high-level Drug NAACCR concepts and that this is OK for the time being.
Disambiguate the Hemonc.org “OR” regimens into multiple regimens.
