What is the primary purpose of a Master Patient Index (MPI)?

The primary purpose of a Master Patient Index (MPI) is to maintain patient identity and activity log. The MPI serves as a critical database that holds unique identifiers for patients, ensuring the accurate tracking of patient demographics and their interactions within the healthcare system. This includes linking various records, appointments, and treatment histories to the correct individual, thereby preventing duplication and ensuring that all patient information is correctly attributed to the right person.

By maintaining a comprehensive and accurate log, the MPI supports healthcare providers in delivering consistent and coordinated care. It facilitates access to patient information by different departments and systems within a healthcare organization, allowing for better patient outcomes and a more efficient healthcare delivery process.
