Which term describes a centralized data store designed to retrieve clinical information from multiple sources?

• A. Electronic Health Record
• B. Clinical Data Repository
• C. Health Information Exchange
• D. Master Patient Index

Answer: (B)

A centralized data store that brings together clinical information from multiple source systems is the Clinical Data Repository. This kind of repository collects data from various places—electronic health records, lab systems, radiology, medications, and more—then stores it in a unified structure so clinicians can pull up a complete, longitudinal view of a patient from one place. The key idea is integration and accessible retrieval across different care settings, which supports better care coordination, analytics, and decision-making. In contrast, an Electronic Health Record is typically the digital chart used within a single organization, focusing on the patient’s record in that setting rather than aggregating data across multiple sources. A Health Information Exchange refers to the network and processes that move data between organizations to enable sharing, rather than being the central store itself. A Master Patient Index handles consistent patient identification across systems, ensuring the right patient’s data are matched, but it does not serve as the centralized clinical data store.
