Harmonization of Data Elements

• Harmonization of the Data elements was coordinated by the ACC and DCRI via a governance group that consisted of practicing cardiologists

• Data was collected from all over the USA• DCRI also has international clinical studies• The focus of the harmonization effort was from the following

registries (from 23,000 hospitals across the country) using >10.5 million records (data several years old):

– Cath PCI (CAD) – Action(STEMI) – ICD (Devices) – ACC top 100 data elements

HL7 Balloting• We needed 27 affirmative votes to pass ballot and we received 35• We received very constructive comments from several voters.  • At the HL7 working group meeting in San Diego, the team reviewed the

comments and determined they would add considerable value to the model.  

• Our team in collaboration with members of the HL7 Clinical Interoperability Council,  decided to incorporate the revisions into an updated version of the DAM and submit it as CV DAM version V2.1 for review later this fall.  

• A follow-up review or ballot cycle is customary when structural changes to the model and/or changes to the clinical content of the model are made.  

• This cycle will give all stakeholders an opportunity to review and accept the updates before the model is published as an informative standard.
