This class points to an administration of the CAGE Assessment Instrument to the Patient. The VA's SCIDO system contains a number of Assessment Events which could conceivably be used in other systems (such as a Behavioral Health system). This class simply serves to link the CAGE assessments in SCIDO to the more general CAGE Assessments modeled in the Assessments package. Logically, neither this class nor the parent SCI_Assessment should exist, but rather the SpinalCordRegistration class should point directly to the relevant CAGE assessments.
