Inspec treatment codes

Inspec assigns treatment codes to indicate the approach taken to a subject by the author of a source document.


Treatment codes are especially useful where a search has produced a large number of documents on the required subject. Treatment codes offer a means of selecting those records which are most relevant. A document may have more than one treatment code.
