The document outlines a three-level approach to achieving meaningful use of an EMR system in an ambulatory care setting. Level one involves basic EMR adoption through standards-based systems, reliable documentation of health information, and e-prescribing for over 80% of prescriptions. Level two is an integrated EMR system where advanced functionality is incorporated into daily workflows and data is used to track performance and outcomes. Level three is an IT-enabled community where data drives initiatives like population health management and patients can access health information through portals.
