What is an Enterprise-Wide Master Patient Index?

In Health Information Management, using a Master Patient Index or MPI is important to healthcare facilities because it allows healthcare staff to access a previous patient's history quickly and effortlessly. This also helps healthcare workers identify patients with same names or other overlapping data. Healthcare facilities that share patients may use an Enterprise-Wide Master Patient Index or EMPI.

Types of data you would expect to see in an Enterprise-Wide Master Patient Index or EMPI or EMPI are the same as the  Master Patient Index or MPI:

• Hospital identification number
• Facility identification 
• Account / Visit number
• Name / Alias / Maiden name
• Date of birth
• Gender
• Race / Ethnicity
• Home Address
• Telephone or Cell phone number
• Social Security Number
• Admission date
• Discharge date
• Encounter service type / location
• Primary Physician
• Patient disposition
