Hi
Documentation of the COST table in CDM v5.4 is somewhat lacking. There are no user guide descriptions for the various fields.
Found some outdated documentation here which seems to still be fairly accurate so that could be quickly added to the CDM v5.4 documentation fairly easily.
In terms of conventions, would like to suggest that the cost_domain_id be specified as the name of the event table containing the event record with which the cost is associated (e.g. “drug_exposure” instead of domain “drug”)
