Insufficient interoperability prevents effective use of health data across the facility or system and does not support continuity of care at the patient level. The National Quality Forum, at the request of the Department of Health and Human Services, has developed in the following summary report, a common framework and measure concepts to serve as a foundation to address the current gaps in the measurement of interoperability and its impact. Key informant interviews revealed the following themes and ideas: the creation of a comprehensive patient record that is accessible without logging onto multiple systems, allowing providers to attain access to a complete patient medical file, and making data in the clinical workflow, readily available in a protected format.
