Over 270 million occupational accidents happen each year. These cause high costs and losses in work time. An active therapy management approach is therefore important The Weller system offers a comprehensive model for accident insurer case handlers. The Weller guide contains 170 principal diagnoses with over 450 diagnosis templates ordered by degree of seriousness. ? There are standard prognoses for the length of time a person will be unable to work for each injury type This takes account of the type of activity. Any overrun against a target time indicates specificities in the course of a therapy and the need for individual case support. The Weller guide is also used for improved communication between all actors in a therapy process.

The Weller system also comprises a central database (UVCD) with details of length of time and cost for closed cases that have been entered by all involved insurers. A good basis for evaluations and improvements.

Users in Germany have achieved an average of 25 per cent lower incapacity time with the Weller therapy management system against unmanaged therapy approaches.

• Weller system as a sophisticated IT proposal, not requiring great technical efforts, for integration in a variety of user systems (XML data format, web app, web service);
   
• integration of Weller into tertiary level courses (bachelor's degree - German Statutory Accident Insurance).
