Clinical data repositories (sometimes called Clinical Data Warehouses) are real-time databases that combine patient data from multiple sources into one easily readable document or application. An abbreviation for a Clinical Data Repository is CDR. Information found within the dataset include laboratory results, patient information, preferred pharmacy information, and ICD-9 codes. CDRs are primarily used by larger hospitals or for education and/ or research. These systems are not flexible. When the organization grows or shrinks CDRs are unable to adjust to the specific organization’s needs and function simply to query and retrieve information.


CDRs can be used during medical trials to mine medical data quickly and efficiently. The data can be monitored and aggregated in real-time. The ability to have in depth data analysis and ability to filter data you do and don’t want to see.
Clinical data repositories are not without any faults though, as most are not interoperable with other hospital technologies. These systems aren’t completely secure as each source it draws data from security is compromised in the combination of the data. The report formats as well as contributing tools aren’t standardized, so it can be a challenge just finding compatible technologies.
