What does the MPI serve as in a healthcare facility?

The Master Patient Index (MPI) serves as a permanent record of all patients treated in a healthcare facility. It is a critical component of health information management that ensures accurate patient identification and helps maintain the integrity of patient records. The MPI contains key demographic information for every patient who has received care, linking all data related to that patient across various encounters, departments, and services within the facility. This comprehensive record can include names, addresses, date of birth, and other identifying details, allowing for effective tracking and management of patient information over time.

Having a well-maintained MPI is essential for ensuring continuity of care, supporting patient safety initiatives, and aiding in the management of healthcare services. It acts as a central resource for reference and verification, which is crucial for clinical and administrative functions within the healthcare environment. By serving as the foundation of the patient's electronic health record (EHR) and facilitating the coordination of care, the MPI plays a vital role in health information governance.
