National members join IHTSDO and have rights and responsibilities that are set out in the Articles of Association (see Schedule 3). The IHTSDO has developed a Fact Sheet on Membership Benefits (August, 2009)
Affiliate Licenses to use SNOMED CT and related standards are available from each country's National Release Centre.
IHTSDO has two categories of national members. The Charter Members are those countries which together launched the IHTSDO in March 2007: Australia, Canada, Denmark, Lithuania, The Netherlands, New Zealand, Sweden, United Kingdom and the United States. Ordinary members are those countries which have joined IHTSDO subsequently – and are going to.
While remaining a member of IHTSDO, the national member is entitled, but not required:
The IHTSDO is established as an Association under Danish law and its governance and advisory structure can be viewed here.
We welcome new members.
Becoming a national member of IHTSDO is straightforward. To begin the process, simply contact us.
The first formal step is to send a letter to IHTSDO indicating:
A sample specification for this letter is available here.
Once received, application letters are sent to the Management Board of IHTSDO for approval. After approval, IHTSDO will invoice the prospective member for the joining and annual fees. These fees are established on a "fair share" basis, based on a country's national income and the cost of developing, maintaining, and supporting SNOMED CT and related standards.
At that point, IHTSDO will also ask for national contacts so that we can help to accelerate use of SNOMED CT and participation in its development, maintenance, and governance in the new member country.
