Our Mission

“To provide a comprehensive framework and related standards for the exchange, integration, sharing, and retrieval of electronic health information that supports clinical practice and the management, delivery and evaluation of health services. Specifically, to create flexible, cost effective standards, guidelines, and methodologies to enable healthcare information system interoperability and sharing of electronic health records. 

These efforts enable effective, efficient communication between the constituents of the healthcare community as represented by our membership, which consists of an international community of healthcare organizations, vendors, healthcare information systems developers, consultants, systems integrators, and related public and private health services agencies. 

The mission of HL7 encompasses the complete ‘life cycle’ of a standards specification – development, adoption, market recognition, utilization and adherence. The HL7 specifications are unified by shared reference models of the healthcare and technical domains.”
