Suggestion for REL and RELA
It will always be the case that the value set designer knows whether the specified UI is a CUI or an AUI. Further, it will never be the case that a given UI matches both a CUI and an AUI. For these reasons, I'd suggest replacing REL and RELA with the following.
| Description | Property Name | Property Operators | Value | Comments | SQL clause for '=' operator |
|---|---|---|---|---|---|
| Relationship (A) | [REL] | in/= | [CUI:]Value | REL (:rel) is one of SY, SIB, RN, PAR, CHD, RB or RO, and Value is a RXCUI. | and RXCUI in (select RXCUI1 from rxnrel where REL = :rel and RXCUI2 = :value) |
| Relationship (A) | [REL] | in/= | AUI:Value | REL (:rel) is one of SY, SIB, RN, PAR, CHD, RB or RO, and Value is a RXAUI. | and RXCUI in (select RXCUI from rxnconso where RXAUI in (select RXAUI1 from rxnrel where REL = :rel and RXAUI2 = :value)) |
| Relationship (B) | [RELA] | in/= | [CUI:]Value | RELA (:rela) is one of the relationship types immediately below, and Value is a RXCUI | and RXCUI in (select RXCUI1 from rxnrel where RELA = :rela and RXCUI2 = :value) |
| Relationship (B) | [RELA] | in/= | AUI:Value | RELA (:rela) is one of the relationship types immediately below, and Value is a RXAUI | and RXCUI in select RXCUI from rxnconso where RXAUI in (select RXAUI1 from rxnrel where RELA = :rela and RXAUI2 = :value)) |
