History

The HL7 Organization was formed in 1987 by a group of vendors and consultants.

These user groups and vendors share a common goal – to simplify the implementation of interfaces between computer applications.

Meetings are held approximately every four months in locations throughout the United States and internationally.

The HL7 organization has continued to grow over the years.
