Lately there has been a lot of discussions whether CCR will fade out and HL7 CDA CCD emerge as the victorious champion.
Why does there have to be a winner?
In my opinion they are both useful and each have their intended audience.
we should be thinking more about developing solutions that can aid in
converting from one document type to another rather than expecting one
or the Other to disappear.
CDA CCD was derived from CCR but
modeled from HL7’s RIM (Reference Information Model). HL7 is an
organization that is formed by large healthcare enterprises such as:
RHIOs, HIEs, Federated Healthcare Organizations, IDNs, vendors and
These large organizations are likely to follow HL7 standards since
they actively participate in defining them. The HL7 CDA CCD is more apt
to exchange complex healthcare information based on well defined
CCR was created by ASTM under the sponsorship of the AAFP (American
Academy of Family Physicians). CCR is simpler and more suited for
implementation by small software development companies. In my opinion
it is also a better way of sharing information with the consumer (e.g.,
Google adopted the CCR standard for the consumer health data
repository. Microsoft adopted both for HealthVault. I think Microsoft
was wiser since it’s the market that finally makes the choice and not
the SDOs, vendors or the government.

Both have good points but I tend to agree more with one of them. :-)
while back ago Dr. David Kibbe posted a blog on this topic as well. Dr.
