HL7 and International Standardisation

What does HL7 stand for?

HL7 stands for Health Level Seven. Health is self-explanatory, while Level 7 refers to the seventh layer of the International Standard Organisation (ISO) Open System Interconnect (OSI) basic reference model (ISO 7498:1984). OSI is the standard model for networking protocols and distributed applications, which became a standard in 1983. HL7 was formed in 1987, at about the same time that EDIFACT (ISO 9735:1987) and SGML (ISO 8879:1986) became international standards.

What is a Standard?

The ISO definition of a standard is a document, established by consensus and approved by a recognised body, that provides for common and repeated use, rules, guidelines or characteristics for activities or their results aimed at the achievement of a maximum degree of order in a given context.

Is HL7 a recognised body?

Yes. Since 1994 HL7 has been an accredited Standards Development Organisation affiliated to ANSI (American National Standards Organisation). HL7 procedures are audited by ANSI.
