Figure HSR-3. Number of opioid maintenance treatment clients as rate per 100 of the estimated number of problem opioid users, 2004 and 2005


The graphic shows the estimated or reported number of opioid maintenance clients as a proportion of the number of problem opiod users, estimated by various methods, in each country with available data.

The symbol indicates a point estimate, a bar indicates an uncertainty interval. TM = treatment multiplier estimation; PM = police multiplier estimation; MI = Multivariate Indicator Method.

Based on countries' estimates of problem opiate use (POU), estimates or estimates of problem drug use and injecting drug use where case definitions in the country's estimates correspond to POU.

Austria: data are for 2004. Case definition used is problematic opiate use or poly-drug use, including opiates.

Malta: case definition used is 'daily heroin users'.

Norway: estimate of IDUs is based on mortality multiplier method for 2004 (drug-related deaths data in Norway shows 96% of deaths are opiod-related.)


See the data on number of clients in substitution treatment in Table HSR-7. Detailed information on substitution registries are provided in Table HSR-10. The problem opioid use estimates can be found in Table PDU-2 part(ii) and Figure PDU-1. See also 'General notes for interpreting data' on the Explanatory notes and help page.
