The wording in the first line below should remove the word ‘consistently’. It is redundant with 'To avoid variation'. Also, ‘consistency’ is mentioned in the next line.:

To avoid variation in the use of FHIR Resources and metadata consistently across eCQMs and clinical decision support (CDS), a quality-related implementation guide based on a logical data model is essential.  In the US Realm, eCQMs SHALL use FHIR Quality Improvement Core (QICore) profiles as the data model to maintain consistency.
