Health Level Seven


Health Level Seven (HL7) is an ANSI-accredited Standards Developing Organization which develops and publishes protocol specifications for application level communications among diverse health data acquisition processing and handling systems.

Having began in 1987, HL7 now has thousands of members from all over the world. HL7 also has six different international affiliates outside the United States: Australia, Canada, Finland, Germany, The Netherlands, and New Zealand, with several other countries pending organization and approval.

The HL7 v 2.3 Standard supports information exchange for patient administration, financial management, orders, observation reporting, scheduling, patient referral, patient care, master file updates, information queries, medical records, and information management.

The use of HL7 in health care information exchange can save time and money while increasing the accuracy and timeliness of healthcare information.
