1. 1 TDI &Prevalence First results of pilotproject A.W.Ouwehand W.Kuijpers Lisbon: TDI meeting september 2006

2. 2 TDI & Prevalence Flash back at the project The project The First Data First Analysis Questions /First Answers Comments experts Lisbon: TDI meeting september 2006

3. 3 TDI Measures New treatments. Repeated treatments after an administrative break.

4. 4 Definitions All Treatments: All clients started in reference period. (EMCDDA) Total Treatments: All clients in treatment in reference period (Pilot)

5. 5 TDI does Not Register continuous treatment relations. Give a total view of treatment demand. Give a clear view on trends in addiction and treatment demand. Compare to national reports.

6. 6 Proposal in Scientific Board ….. memo to extend the TDI to total prevalence In its current form, however, the TDI does not give insight into the total treatment demand. Especially chronic clients that have been registered for longer periods are not reported by TDI-figures. Addiction being a chronic disease, chronic clients consequently form a substantial part of the total treatment demand. To give an impression about a country's total treatment demand and the number of drug addicts that are being reached by treatment, it is therefore proposed to extend the TDI to all drug treatment cases for a given reporting year. Comparing incidence cases to existing cases will also give further insight into the division between new and old drug problems in Member States of the European Union.

7. 7 Questions to start Would it be possible to deliver the total treatment demand besides the 2005 TDI data? Could it eventually be done at a later date (year)? How can we advice the EMCDDA (Management Board/Scientific Board)? Will it be possible for all/some countries? In what way does this effect the figures of the EMCDDA and the presentation of TDI data?

17. 17 Questions/First Answers Would it be possible to deliver the total treatment demand besides the 2005 TDI data? Several countries are able to deliver these data Could it eventually be done at a later date (year)? Yes How can we advice the EMCDDA (Management Board/Scientific Board)? To continue and widen up the experiment on voluntary base Will it be possible for all/some countries? Has to be further discussed/investigated In what way does this effect the figures of the EMCDDA and the presentation of TDI data? Most likely significantly
