The current web application Decision Table Editor is an instrument which allows the controlled revision of the decision tables. The decision tables are annually revised for the inclusion of the WHO updates and for the correction of errors. This revision is a very complex process which needs to be highly controlled and documented. In fact the current decision tables include about 30 million of relationships between codes.

The objectives of the Decision Table Editor are:

• to handle the simultaneous and coordinated access to the tool of experts from different countries for updating decision tables;
• to document the annual updates;
• to check duplications and inconsistencies;
• to avoid manual intervention on the tables;
• to produce the decision tables used by the IRIS system and by manual coders;
• to store and retrieve annual version of the tables.

The Decision Table Editor has been developed in the framework of the collaboration with the IRIS Institute. The Iris Institute emerged from an international cooperation for the deployment, maintenance and development of the Iris software, an electronic system for automated coding of causes of death. The Iris Institute is hosted at the DIMDI (German Institute for Medical Documentation and Information) and the current cooperating partners are from France, Germany, Hungary, Italy, and Sweden.

This application was used to produce the 2014 tables. Previous versions are available at the Iris Institute website.
