Matching Records ! While it is relatively simple to get a computerized credit history for anyone who has had a credit card, obtaining a computerized medical history remains difficult if not impossible. There are many potential benefits of having a computerized medical history, including the elimination of duplicate tests and procedures, better access to patient histories for emergency use, elimination of reentry of historical data, and greater accuracy. To make all patients medical records in the U.S. accessible to care providers, electronic medical records need to be linked together using a massively distributed Master Patient Index (MPI). A MPI is a facility that correlates and crossreferences patient identifiers and performs a matching function with high accuracy in an unattended mode. The need to combine records from different organizations exists for many reasons, including patients moving and/or changing health care providers. A massively distributed MPI will provide links to encounter data resident on provider databases and provide a patient summary. The summary will list the links to the encounter documents distributed all over the network. This summary can be loosely considered the patient s home page or a table of contents for the patient s massively distributed health
