Abstract

To integrate patient-centric data from multiple, separate sources, individual patient records must be accurately identified and linked. The absence of a universally applied unique patient identifier as well as heterogeneity of data format, availability, quality, and completeness across different eHealth systems and organizations hinders consistent patient identification. A client registry implements matching algorithms using available, unique patient identifiers and demographic attributes to link patient records residing in separate health care organizations within a health information exchange. The linkage process provides a single coherent, longitudinal health record for each patient, supporting tasks such as care coordination and research efforts. This chapter focuses on the issues related to developing unique patient identifiers, matching patient records, and the role the client registry plays in the process.
