Enterprise Master Patient Index (eMPI)

Description

Enterprise Master Patient Index (“eMPI”) is a system to aid the identification of patients and minimise the number of duplicate health records held for each patient. It achieves this by collecting key data from NHS Wales’ clinical systems, including name, address, date of birth and sex, from across NHS Wales Health Boards. This then creates one “gold standard” patient identity record that is intended to best represent the individual. The eMPI is used by all the national systems and services delivered by NWIS, therefore is the key solution to ensuring that the patient information required by the other national solutions is accurate.
