Dear Tom: You write OIDS: "I have never seen a convincing argument for their use."
In the case of the Austrian EHR (www.elga.gv.at) OIDs are used to enforce authenticy as part of the "forensic" issues. Everything (organisations, codelists, guidelines, numbering systems, single patient IDs, really every entity that appears in the Austrian EHR) is tracable via its OID. As you correctly say, an online tool is therefore necessary. In Austria this has gone operative last year and here it is: https://www.gesundheit.gv.at/OID_Frontend/ It has a tree view (among others) and enables everybody to trace every entity back to the origin. The use of OIDs does not dictate that the OID of every entity is actually registered in the central OID server. The OID server keeps track of the root OIDs. Organisations put leaves to the tree as needed in many cases. The agreement in Austria was that full-scale identification of "everything in the EHR" is indeed a core requirement. This is satisfied by OIDs in Austria. Hope this helps, greetings, Stefan On 07.12.2012 18:18, Thomas Beale wrote: > On 07/12/2012 12:14, Stefan Sauermann wrote: >> Dear Ian, >> OIDs are a requirement in some legislations, including the Austrian >> EHR space. >> Can you please explain why they "become a nightmare"?
