Master patient index (MPI) solutions are built to match patient data in healthcare organizations and are usually built into an EHR system. MPIs cannot match identities outside of the EHR and therefore limit the accessible information on a patient.
EMPIs are standalone products that are deployed in addition to EHRs. Their more sophisticated algorithms make matches across siloed data sources that MPIs can’t make. Still, as standalone solutions, EMPIs lack the support to manage patients, providers, and consumers with one platform. To learn more about the difference between EMPI and MPI, read our comparison.
