HL7 Vision

To create the best and most widely used standards in healthcare.

HL7 Mission

HL7 provides standards for interoperability that improve care delivery, optimize workflow, reduce ambiguity and enhance knowledge transfer among all of our stakeholders, including healthcare providers, government agencies, the vendor community, fellow SDOs and patients. In all of our processes we exhibit timeliness, scientific rigor and technical expertise without compromising transparency, accountability, practicality, or our willingness to put the needs of our stakeholders first.

HL7 - What Does it Mean?

"Level Seven" refers to the seventh level of the International Organization for Standardization (ISO) seven-layer communications model for Open Systems Interconnection (OSI) - the application level. The application level interfaces directly to and performs common application services for the application processes. Although other protocols have largely superseded it, the OSI model remains valuable as a place to begin the study of network architecture.

HL7 Strategic Initiatives

The HL7 Strategic Initiatives document is a business plan for our products and services and was designed specifically to meet the business needs of our members and stakeholders. Derived from collaborative efforts with our members, government and non-government agencies and other standards development organizations, the Strategic Initiatives are comprised of five high-level organizational strategies that are supported by a detailed tactical plan with clearly defined objectives, milestones, and metrics for success.
