Hospital data management information systems designed to provide a common patient database for use throughout the healthcare facility (i.e., a master patient index or MPI). These systems typically establish a patient record and an MPI number for each patient during the patient\'s first visit (regardless of the type of visit or admission). The common MPI may be used through the entire healthcare facility independent of any records created for a specific hospital department. MPI hospital information systems include hardware (e.g., a local network including workstations, servers, and links) and firmware and/or software; they may be operated as stand-alone systems or can be assembled into an integrated hospitalwide information system.
