HL7: Health Level Seven

HL7, Health Level 7, is a nonprofit organization that develops and publishes standards providing a framework for interoperability of health information. Headquartered in Ann Arbor, United States, HL7 standards are used by its approximately 500 corporate members, representing over 90% of information systems vendors serving healthcare worldwide. HL7 standards have since been adopted by several other countries on a national level, as well as by ISO (International Organization for Standardization). Standards from HL7 are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: [email protected] or 1-212-642-4980 or Request Proposal Price.
