The Master Patient Index (MPI) is a critical tool in the healthcare industry used to reference and track patient records across various departments and facilities. It serves as a comprehensive database that ensures each patient's medical record is accurately linked to their identity, thereby facilitating the gathering of complete medical records.

The MPI plays a vital role in maintaining the integrity and accuracy of patient information, enabling healthcare providers to efficiently access all relevant data associated with an individual patient’s care history. By having a centralized point of information, the MPI minimizes the risk of duplicate records and errors, thereby enhancing patient safety and care continuity.

The Notice of Privacy Practices outlines how patient information may be used and disclosed but does not assist in compiling medical records. The Information Management Plan typically relates to the processes and policies governing the management of health information rather than the tools used for record gathering specifically.
