DHIEX is the regulatory framework that gives Ontario Health the ability to define and implement the health information standards and requirements for use in interoperability specifications. It regulates digital health information exchange in Ontario for consistent sharing of meaningful health information across health systems for the benefit of patients and health care providers.
