Abstract
Health care reform and the use of electronic health record systems is dramatically changing the health care community. High adoption of health information technology has created an opportunity to improve population health by leveraging data collected by health systems. This project describes the informatics characteristics of current and emerging clinical data repositories among Minnesota health care providers. Results will provide a critical understanding of the status, challenges, and opportunities for leveraging the large investment in health care data systems to better support public health prevention programs, epidemiology, and surveillance to improve population health, identify health disparities, and advance health equity.
