The Illinois Health Information Exchange helps providers meet Meaningful Use public health reporting. Connectivity to the ILHIE provides connectivity to the Public Health Node, allowing providers to submit their public health data to one central hub through a single interface. I-CARE, or Illinois Comprehensive Automated Immunization Registry Exchange, is a web based immunization record-sharing application developed by the Illinois Department of Public Health (IDPH). The application allows public and private healthcare providers to share the immunization records of Illinois residents with other physicians statewide.
