Leveraging the Master Patient Index in Public Health Surveillance through Collaboration between Illinois Department of Public Health and the Illinois Health Information Exchange


Meaningful Use (MU) Stage 2 public health reporting for Eligible Professionals (EPs) included a menu option for ambulatory syndromic surveillance. Review of currently existing models lead to a collaboration between the Illinois Health Information Exchange (ILHIE) and IDPH to build services that would support the use of the MPI, a database that can uniquely match records across systems. The MPI providers a mechanism for public health to manage multiple data streams, while maintaining confidentiality of health information and supporting the mission of public health to identify patterns of illness, apply effective interventions and conduct program evaluation. This initiative will allow IDPH to extend the use of the MPI to other surveillance domains, including hospital discharge, communicable disease, cancer and extensively drug resistance organism reporting.


This presentation will describe public health efforts to improve data collection by utilizing technology that supports record linkage through the implementation of the Master Patient Index (MPI). The initial use case will be applied to ambulatory syndromic surveillance at Illinois Department of Public Health (IDPH). It will include applications for incorporating the MPI into currently existing public health surveillance data and benefits to data integration and bidirectional information exchange.
