CINA will assist HealthBridge, one of the nation's largest community Health Information Exchanges, in a data extraction and aggregation project to satisfy the requirements of a federally funded community-wide project to be initiated throughout regions of Cincinnati, OH. This initiative will attempt to demonstrate that data extracted from physician-based electronic medical records and practice management systems throughout the HealthBridge service area can be successfully integrated with HealthBridge's own clinical data for quality improvement purposes.
