A '''Clinical Data Repository''' (CDR) is a real-time [[database]] that consolidates data from a variety of clinical sources to present a unified view of a single [[patient]]. It is optimized to allow [[clinician]]s to retrieve data for a single patient rather than to identify a population of patients with common characteristics or to facilitate the management of a specific clinical department. Typical data types which are often found within a CDR include: clinical laboratory test results, patient [[demographics]], pharmacy information, [[radiology]] reports and images, [[pathology]] reports, hospital admission, discharge and transfer dates, [[ICD-9]] codes, discharge summaries, and progress notes.

CDRsA addCDR 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.
