In order to be able to combine research data from several projects or studies and assign them to a single person, so-called record linkage is necessary. It requires both a duplicate procedure and a unique system-wide identifier, to which both the person-identifying data and individual local identifiers of the source system (e.g. laboratories, study centres, etc.) are assigned. Since this must be done in a fault-tolerant and traceable manner even in the case of incomplete or incorrect person-identifying data, a sustainable Record Linkage and Identity Management is required.
E-PIX enables probabilistic record linkage and implements the concept of a Master Patient Index. The integrated identity concept allows potential synonym errors to be detected automatically and supports their resolution using a user-friendly graphicalinterface. The recognition of duplicates is based on freely definable parameters and the Levensthein distance. Consequently, possible synonym errors are logged automatically and can be resolved using the corresponding functions.

Recording persons

Person-identifying data can be recorded and processed including a variety of demographic characteristics, different contact addresses and project-specific parameters.

Resolving duplicates

Configurable algorithms enable the a) detection and b) resolution of duplicate person-datasets either automatically or manually using the graphical user interface.

Processing lists

The configurable import and export of Excel lists supports researchers in transferring legacy data into E-PIX® and in working with other software products.
