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

The primary function of a Master Patient Index (MPI) is to serve as a permanent record of patients treated at a healthcare facility. This system is critical for maintaining accurate and complete patient identification and ensuring that healthcare providers have consistent access to patient information across different systems and departments within the institution. The MPI consolidates essential demographic information, linking patient records and supporting the continuity of care. By providing a central repository for patient identities, it helps reduce duplication of records and enhances the overall management of patient data, ultimately improving patient safety and care coordination.

While other functions listed, such as collecting patient insurance information, managing clinical trial data, and facilitating online patient scheduling, are important aspects of healthcare management, they do not specifically highlight the core role of the MPI in maintaining a comprehensive and accessible patient record across various healthcare services.
