The Classification Browser
| Sweden, in contrast to most other
European countries, has a tradition of using adjusted
versions of the International Classification of Diseases
(ICD) within primary health care. Along with the Swedish
version of the tenth revision (ICD-10), a primary health
care classification has been developed together with an
additional three-dimensional system for classification of
diagnoses according to location, origin, and type. The
new codes correspond to either the three or four
character level of the ICD-10, and the total number of
categories (disparate diagnoses) is 972, i.e.
approximately one tenth of the contents of the ICD-10.
The Classification Browser is a World Wide Web accessible interface to a database containing the computerized version of the classification. The aim of the project, which is a cooperation with the Medical Informatics Council of the ??????? is to present a clinically more relevant view of the classification than the original chapter structure taken from the ICD-10. The system is based on concept representation implemented by means of a data model developed within the Spriterm project. It enables representation of hierarchical as well as semantic relations such as rules for relative priority within the classification. Entities corresponding to disparate levels of the classification are implemented as concepts within the model, and corresponding terms are assigned a "used as" property to reflect their usage within it. These can, for instance, be preferred terms, diagnostic codes, or chapter titles. Thanks to the additional three-dimensional system, code selections suitable for medical audit and quality assurance, such as identification of encounters with respiratory tract infections, musculoskeletal symptoms, and infectious diseases, can be done with combinations of concepts. These combinations can be performed without respect to the structure of the original classification. You can find a working release of the Classification Browser
