There are certain specific standards initiated, developed and implemented by the organization viz. HL7 v2.x, v3.0, HL7 RIM etc. Version 2.x messaging standards are used not only in USA but also worldwide typically between information systems inside the same hospital, between hospitals and external laboratories and diagnostic centres.
