This "ballot for comment" has been provided to solicit feedback on changes we would like to incorporate in the CDA R2.1 standard.  As it has been 12 years since the CDA R2.0 standard was published, and it seemed appropriate to incorporate a wider discussion on CDA Implementation Guides and templates in general.  As a result, we have added a new section, "Section 4 - CDA Implementation Guides".

As we indicated in the CDA R2.1 project scope statement, we have pre-adopted the new vocabulary binding syntax, where  CWE has been replaced with "Open" and CNE are replaced with "Closed" and Fixed indicates a single code binding that can not be changed in implementation guides. Refer to "Section 2.3 - Vocabulary Use in CDA" for more on these changes. And likely the most notable change in this new version of the CDA standard, is "Section 5 - CDA Design", where we have included a series of CDA RMIM diagrams and updated class attribute and value set tables to assist readers in understand the CDA's design and capabilities.  We are interested in all feedback, but thought it important to call out these sections and content for your review.

This "May 2018 Normative Ballot" has been provided to solicit feedback on a number of substantive changes made to the CDA R2.1 since the Sept. 2017 Normative Ballot.

The scope of this ballot will be limited to the following substantive changes:

  1. In section 5.3.6.8 SubstanceAdministration, SubstanceAdministration.consumable relationship shall be 0..1 rather than 1..1 (or declared conditional).
  2. In section 5.2.3.5.4 HealthCareFacility the binding on it's class code should not be fixed to SDLOC, but rather SDLOC should be defaulted out of the V:RoleClassServiceDeliveryLocation value set. In the CDA R2.0 schema this was a defaulted and not a fixed binding.
  3. In the datatypes.xsd schema, a definition has been created for the IVL_RTO data type. This was originally supported by the Normative standard for Data Types R1, but not expressed in the schema provided with CDA R2.0. It has been added to CDA R2.1 package to support ObservationRange use cases.
  4. In section 2.1 HL7 Reference Information Model, the binding has been changed back to RIM 2.35 as data types R1 were not supported in parts of the V3 tooling for RIM 2.36c.

Note: The publication is now generated from the V3 publication process. Tables, text and formatting may appear somewhat different. Every attempt has been made to ensure that the content is consistent with the previous versions of the CDA R2.1 ballot. There is a known issue with the generated table of contents, where links with the same names will link to the first item with that name. This issue will be resolved prior to final publication.

Any inadvertent content omitted from the previous CDA R2.1 ballot that is identified, will also be considered in scope for this ballot.
