Master Patient Index (MPI)
An identity index that matches patients uniquely and accurately across systems.
Master Patient Index (MPI) is a system that matches and de-duplicates a patient's records created in different systems and institutions under a single unique identity.
MPI detects duplicate records belonging to the same patient and ensures that the data is correctly associated with the right patient; this is critical for patient safety and data quality.
