In computing, an enterprise[-wide] master patient index is a form of customer data integration (CDI) specific to the healthcare industry.
An EMPI will typically provide an application programming interface (API) for searching and querying the index to find patients and the pointers to their identifiers and records in the respective systems.
An EMPI may additionally work with or include enterprise application integration (EAI) capabilities to update the originating source systems of the patient records with the cleansed and authoritative data.
EMPI can be used by organizations such as hospitals, medical centers, outpatient clinics, physician offices and rehabilitation facilities.
The attributes a match engine is configured to use can typically include name, date of birth, sex, social security number, and address.
