The Electronic Health Record (EHR) is a longitudinal electronic record of patient health information generated by one or more encounters in any care delivery setting. The EHR has the ability to generate a complete record of a clinical patient encounter - as well as supporting other care-related activities directly or indirectly via interface - including evidence-based decision support, quality management, and outcomes reporting. In this section you will find many resources that contribute to the ability for healthcare organizations to realize a longitudinal electronic record that spans across the continuum of healthcare.
