A Clinical Data Repository (CDR) is a centralized database that collects and stores patient health information from various sources, such as hospitals, clinics, and laboratories. This repository allows healthcare providers to access comprehensive patient records, facilitating better decision-making and improved patient care. CDRs often integrate data from electronic health records (EHRs), medical imaging systems, and other clinical applications. By consolidating this information, a CDR supports research, quality improvement initiatives, and population health management, ultimately enhancing the efficiency of healthcare delivery and outcomes.
