Health Information Exchange (HIE)  

Master Patient Index (MPI)

The Master Patient Index identifies patients across separate clinical, financial and administrative systems and is needed for information exchange to consolidate the patient list from the various RPMS databases.

The MPI contains records for all the patients from all of the IHS facilities. They are supplied by RPMS in HL7 messages. Each facility record belongs to an enterprise record, which is created by the MPI. Two facility records that represent the same real-life person belong to the same enterprise record. An enterprise record contains its own set of patient demographics called the Single Best Record, which is calculated from the demographics data of its facility records. The MPI generates a unique patient ID, called an EUID, for each enterprise record.

The MPI Enterprise Record consists of one or more facility records.  The best demographic information for the patient will be used to create the Single Best Record.

Facilities - What does this mean to you and how do you get started?

You can participate in patient summary exchange with confidence that you are getting highly qualified matches of patient data utilizing current standards and technology and therefore the best opportunity for patient care based on the most complete picture possible.

Each site will actively participate in the management of the MPI data, by evaluating and resolving any uncertainties in the matches.

To get started using the IHS MPI, please reach out to your local site manager.
