What information is cross-referenced in a master patient index?

• A. Patient age and location
• B. Patient name and medical record number
• C. Patient diagnosis and treatment
• D. Patient insurance details

Answer: (B)

The master patient index (MPI) serves as a critical tool in healthcare information management by uniquely identifying individual patients within a healthcare facility. The primary purpose of the MPI is to ensure that each patient has a unique identifier, which is typically their medical record number, that allows for the accurate tracking of their health records over time. Cross-referencing patient name with medical record number is essential for maintaining an accurate and complete database of patient information. This cross-referencing enables healthcare providers to quickly and reliably retrieve patient records, reducing the incidence of errors that can occur when similar names exist or when patients have been treated in multiple facilities. The MPI also supports continuity of care by ensuring that all pertinent health information is consistently associated with the correct patient. While the other options may contain relevant patient data, they do not reflect the primary function of the master patient index. Patient age and location, diagnosis and treatment, or insurance details, while important in their own right, are not the elements that define the core purpose of the MPI, which focuses on the unique identification of patients through their names and medical record numbers.
