EHR Standards are the building blocks for the exchange of health information. They provide a common reference framework to promote uniformity in the definition and identification of health system components.

This includes messaging and data interchange standards which allow for consistent data flow among systems and organizations, specifying format, data elements and structure. It also includes terminology standards which provide specific codes for clinical concepts such as diseases, problem lists, allergies, medications, and diagnoses. These standards enhance data quality, reduce medical errors and reduce the need for customization of IT solutions across the health care system.
