The Netherlands Drug Situation 2010 - Trimbos-instituut

tient treatment merged with the regular organisations for inpatient treatment within theirregion. As a result of these mergers, the majority of clients are now registered at a centralintake location. Some private clinics, those institutes for mental health care that havenot yet merged with an organisation for addiction treatment, and the addiction units ingeneral psychiatric hospitals are not yet represented in the LADIS.The data in this paragraph are based on the protocol for the Treatment Demand Indicator(TDI) as established by the EMCDDA (Standard Tables TDI_2009_NL_03 andTDI_2010_NL_01). This means that only those clients who have had at least a secondface-to-face contact with an addiction counsellor are included. Moreover, the main part ofthe TDI only includes clients who subscribed in the year of registration. This main part ofthe TDI does not include subscriptions from a previous year that were continued in theregistration year. Subscriptions within the registration year include clients that subscribedfor the first time in their life for a drug problem (first treatments), as well asclients that resubscribed in the registration year. The TDI controls for double counting ofpersons. These criteria are more restrictive than the criteria applied by the holder of theLADIS, the Organization Care Information Systems (IVZ), to assess the annual LADISKey Figures (Ouwehand et al. 2010). The figures presented here will therefore deviatefrom the figures reported elsewhere. The LADIS Key Figures are also reported in theEMCDDA Standard Table 24 (ST24_2010_NL_02).Some further observations should be made: Data will be reported from 1994 onwards, since this is the first year for which IVZ isable to control for double counting. The coverage of the system in terms of participating services has improved over theyears. The small relative increase in opiate clients from 2000 to 2001 is mainly due tothe participation of the Municipal Health Service Amsterdam (GGD Amsterdam) in theLADIS since 2001. "Cocaine" refers to both "cocaine HCL" and "crack cocaine". For 2008, the data have been extrapolated for four missing institutes that were notable yet to deliver data to the LADIS.TrendsBetween 1994 and 2009, the annual number of new clients applying for help at the drugtreatment services varied between eight and eleven thousand, with no clear trend overthe past years. Figure 5.3.1 shows the distribution of the new clients from 1994 to 2009for the drug that was the primary problem for these clients.72
