Modelling and encoding Therapeutic Guidelines: applying ICD-10-AM and European Article Number codes

This article reports on the assignment of ICD-10-AM and EAN codes to 2500 topics in Therapeutic Guidelines (TG). The analysis of the assignment of ICD-10-AM codes in this project has revealed that ICD-10-AM is not capable of describing the complete clinical information in the guidelines series. It is not likely that any existing single classification scheme will be capable of this and that a combination of schemes will be necessary. The TG data model was integrated with the prototype MCCA data model for drug products. This integration indicates that the representation of drugs, while not ideal, is an appropriate means of linking clinical drug reference information to drug product information.
