Abstract
The Read Thesaurus is a comprehensive user-led clinical vocabulary developed from
earlier, and structurally simpler, versions of the Read Codes, with substantial input
from United Kingdom health care professionals. A constituent template table underpins
a range of functions, including semantic definition of concepts using object-attribute-value
triples. Concept representation for surgical procedures has been investigated by a
number of groups and a standard European structure has been proposed. Over 50% ofthe
surgical procedures in the Read Thesaurus have been fully characterised using a number
of attributes each with a defined concept field. We report progress to date and, based
on our large-scale experience, examine the applicability of the European model to
a user-defined terminology.
