A mechanism to reference non-QI-Core, non-US Core profiles will not be available for this publication and availability of such tooling is not clear. Further, no existing eCQMs have indicated need for information exceeding USCDI requirements as specified with US Core. Will add guidance in the QI-Core landing page after section 1.13 (I.e., a new 1.14 titled Identifying Occupational Data for Health) with the following language: The profile inherited from US Core Observation Occupation Profile is based upon the core FHIR Observation Resource and implements the US Core Data for Interoperability (USCDI) Occupation and Occupation Industry requirements. That profile's Example Usage Scenarios include: Query for a patient’s work history Record or update past or present jobs belonging to a patient To obtain information regarding other Occupational Data for Health (ODH)-specific concept as indicated in the ODH version STU 1.3 Artifacts Summary use the QI-Core SimpleObservation profile Observation.code element to reference the exact LOINC code referenced by the specific ODH element of interest (e.g., 74165-2 for History of employment status NIOSH; 11341-5 for History of Occupation, 87510-4 Date of Retirement, etc.).   I.e., what US Core Occupation Observation cannot deliver on, SimpleObservation can.
