A CDR adds complexity by adding another system, a database and storage system, that provider organizations must own and operate. In most cases the additional system stores information that already exists in electronic form on an ancillary system.

Managing such large data repositories is expensive. As the CDR grows and becomes “The” warehouse for all clinical data more effort (time, people, money) is invested to ensure the data is safe, reliable, and always available. This is the “Achilles Heal” of the CDR EMR model.

The idea of placing clinical results in a single system so that policies and procedures can be put in place to ensure adequate back-up, archiving, and redundancy has great appeal. The downsize is the repository becomes very large and the database very complex, and these factors drive the cost of keeping the CDR available 24/7 higher and higher over time.
